Space Engineers - Centre Of The Planet Drilling

Now many of you have been asking about drilling through or to the centre of the planet now after a lot of drilling and tons of explosive we can finally find out what happens.
Disclaimer We have been having some big issues in survival mode we are still working to fix them.

Space Engineer is like a mixture between Minecraft and Kerbal Space Program.
The main purpose of the game seems to be building a space fleet and fight/ally with the other factions. You build your ships piece by piece and the only know limit for the size of your ship is what you computer can handle.

[@busteraycan]

Continue drilling with your hand drill. See you in 5 years.

[@elmobarrethawk3566]

+Burak Baggins it gets deleted

[@sarund9441]

+Garrett MAGISTER “elmobarretthawk9100” hand drill, not ship

[@kabevo9186]

+sebas OBRUTSKY every block despawns in a deep of 10km. I tested it. But you can fly throw it with your suit

[@sarund9441]

SUIT DRILL, NOT BLOCKS STUPID

[@minu2910]

OH MY GOD HE DOESN'T AGREE WITH YOU. CAPS LOCK ENGAGE

[@brothyr]

this is a solid waste disposal method. A real way to get rid of that 2000k kg stockpile of stone.

[@Drives31forhalo]

+Adam R this is genius!

[@karakas9905]

+Adam R Brilliant

[@johnhmstr]

+Adam R Scifi "core waste dump" given form. :-)

[@tris1452]

Or just launch the waste into space...?

[@b2spiritnuke]

+TrisTechUK that creates lag for the server over time

[@Sadorath]

They allow you to drill through planets now.

[@andrasfogarasi5014]

The gravity decreasing as you approach the core is realistic. The further down you get, the less matter will be below you, pulling you down, and more matter above you pulling you up.

[@winddoggo9406]

But the pressure can eventually crush you

[@andrasfogarasi5014]

Christopher Lefont Pressure? Maybe in the future.

[@Sanman-ye9lu]

András Fogarasi well on earth you would die from the radiation from fusion and pressure but on a hollow earth yeah no gravity in the middle

[@anthonyfoster3786]

Stephen Prendergast I must add that matter does control gravity but... another to add in is time. try and study that up. time can change a lot of things even warp space. maybe make a anti- matter engine.

[@LimaHotel807]

Stephen Prendergast fusion? What are you talking about?

[@TuttyGaming]

They should put a "molten core" in the planet, that would make deleting objects much more reasonable. Basically just a spherical object with a lava texture.

[@harrybrohan4602]

TuttyGaming I want fluids like Magma and Lava planets, or gas planets and oceans on the earth.

[@joshuacordeiro207]

next objective: cut a planet in half

[@demonicpain10]

+CasualLetsPlay Also impossible, considering you can't even reach the core much less tunnel through the planet

[@SpecOpsFerret]

+CasualLetsPlay Cut the planet in third? lol

[@FEFELAND]

+Demonicpain10 You can with voxel hands, i just left a comment explaining my experience that i had just now

[@Tjb140]

+Jack Outside the Box I wonder if you removed a large portion of the planet, would it be noticable from orbit?

[@Shinzon23]

+Tjb140 Not really; I tried bombarding a planet for 3 hours with about 25 orbital strike platforms all dropping a constant stream of explosives that ended up blowing a hole roughly 3 km in radius and 1 km deep, but when I view the strike site from orbit I couldn't see it.

[@huub9009]

what are they hiding at 8km depth. a secret keen meme base?

[@Draco_Alpha]

That's actually where they translated Zero Wing.

[@servanious7796]

That's where they hide the Atari E.T. Games....

[@Fraggr92]

It's obviously where they hide the clang

[@extrnalsorce4974]

Huub900 or maybe they are hiding the birth catalyst of the old gods?

[@tommygunengineer9184]

Maybe that's the one and only place where you can see John Cena?

[@gownerjones2]

That sucks. I want to be able to drill *through* the planet and pop out the other end. Man, they need to get rid of the fucking speed limit anyway. 104 m/s are annoyingly dull.

[@samstokesphotovideo]

just download a mod, there's one that increases it to like 500m/s

[@gownerjones2]

***** Thanks, guys, I'll check that out. But the thing is, I want them to get rid of the speed limit altogether. I get that it's hard to do with the physics engine and all that but I really think it would add a big big bunch of goodness to the game if it were to work.

[@dumpygrimbo8623]

theres speed limit remover mods, buts a bitch to stop

[@gownerjones2]

***** That's really unfortunate. It's one of my biggest complaints about this game. I want to build giant ships and accelerate to ludicrous speeds and get in trouble because I didn't think of also decelerating. I want to build fancy mechanisms for quick deceleration, using gravity or maybe something like an aircraft carrier's cable. Basically I want to be able to play with speed in mind in this game and that's just not possible with a speed limit. It's like a hard limit on my inventor's spirit. :D

[@Gelfling66]

+HOLyPumpgun | Gaming again, theres mods that remove the speed limit. and "i get that it's hard to do with the physics engine and all" umm yeah... case and point.

[@Jack1rules]

Hi there, it’s me Jack the time traveler, I come from 3 years later and we now have the ability to drill all the way through the planet in space engineers

[@girf4233]

We do?

[@AfroMan187]

Ima wait to see how many likes this comment has in 3 years before i respond

[@Restilia_ch]

The lower gravity as you go down is actually very realistic. As you go down, you start having stuff above you exerting its own gravity to pull you back up. At the exact center of a perfectly spherical body, you would be in zero G as you are being pulled equally from all sides. This is also why a hypothetical "Tunnel to China" wouldn't need engines. Gravity starts pulling you down, acceleration slows the deeper you go and completely switches to deceleration once you pass the halfway point. Interestingly enough, such a tunnel would have the same travel time from New York to Los Angeles as it would New York to Sydney.

[@refreshfr]

+OtakuMage Wouldn't need engines if your entire tunnel was vacuum, otherwise air friction would slow you down and you'll eventually end up at the center. Plus you have the whole pressure and temperature and the mildly annoying issue of the metal core at the center of our planet... :p

[@gownerjones2]

+refreshfr That pesky, annoying metal core. Destroying dreams and ambitions since 4,540,000,000 BC.

[@Restilia_ch]

refreshfr I said hypothetical, it has many issue of which air pressure is not the least. Casual use ICBMs are a more likely alternative these days.

[@roadtrain_]

+refreshfr metal? i thought we had lava in the center... :/

[@Reivehn]

+Bart Wijshake Molten metallic core. Look up how it works, The lava is called magma in the earth with its gaseous component mixed in, The magma comes up from the mantle, a thin layer of semi-molten rock. We live on top of the earths crust. The crust is in sections called tectonic plates that rest on top of the mantle which flows via heat based pressure currents called convection currents, its all a mix of rocky minerals and metals, Eventually, you get deep enough to reach the outer core, A highly liquid like portion of the core which has heavy convection currents and has many elements including pretty much all metals from hydrogen to francium and even higher up the chain, its the flow of these convection currents in the outer core that give the earth its magnetic field, the north and south polar magnetic field. Then you have the inner core, which is made of the same substance as the outer core, but due to how much pressure is being forced onto it from the weight of the outer core, mantle, crust and even the air all around us, its squished into itself from all directions and acts more like a solid, due to mass compression. contrary to popular belief, the inner core is not what makes the earths magnetic field, but from what we can tell, it may spin. Also the outer layers of the inner core and inner layers of the outer core may sort of break away and reform into each other as they bridge the gap of liquid and solid. Thats geology for ya! :)

[@Pyrociraptor]

I was expecting some giant alien spider spawning as you reached the center...

[@the11382]

How about drilling diagonally to try to "dodge" the core?

[@giin97]

7k down, 60k total to the center. You really aren't getting very deep. You wouldn't be diagonal, you would eventually be horizontal.

[@Creaform003]

+Ryan Gunn any core dodging would by definition become horizontal.

[@giin97]

+Adam Boyd Lol, you make a good point :P

[@Noob-dj6pi]

+Adam Boyd no I think it would act more like a week spherical generator at the core just need to thing round

[@Creaform003]

Ian Fitzgerald It was a joke, sorta... Unless you go through the core, if you continue in a straight line as some point you are going to be moving perpendicular to the gravity field.

[@almightyeragon5265]

If there weren't a speed cap you could use this kind of tunnel as a slingshot for ships getting out of orbit

[@bewati1]

+Almighty Eragon The speed effect would be zero, since gravity works the other way when you go past the core.

[@BlackAnno3397]

There are mods increasing the speed limit

[@almightyeragon5265]

you would have to use thrusts to speed up as you go down, its just to make gravity and the distance help you reach escape velocity

[@ViniciusNegrao_]

+Almighty Eragon That's unecessary work, it's even more expensive to make it go through the center of Earth than just have it simply fly off, I can work the math for you if you want...

[@Masterofworlds]

it would't work as well as you're thinking. like frank said there's gravity on both sides of the planet... lets just say there was a perfect tunnel going straight through the center of the earth. you jump down... assuming no air is in the tunnel your acceleration would start becoming slower and slower till you reach the core, then you would start accelerating in the opposite direction (or decelerating). then once you reach the other side of the tunnel, your velocity would become 0 and you would just start the process all over again.

[@ZackRToler]

Should still do a race to see who can get to the deletion point first.

[@Thelothuo]

+ZackRToler You'll know when you win when your ship disappears and you're stranded in the bottom of a 7km hole.

[@Nickuncle]

+Thelothuo "I won!" "Congrats Tazoo!" "Thanks guys! Wait, where are you going?! Don't leave me!"

[@mikauanaki4866]

+Nickuncle *they begin filling in the hole*

[@Thelothuo]

Jacob Lewis Can't rebuild voxels in Survival at the moment, but dropping large quantities of small rocks would work.

[@alphamoonman]

+ZackRToler The winner doesn't exist.

[@MarekMoowi]

In reality deep inside planet gravity is lower, because mass of planet is surrounding object. In theory in planet core gravity should be almost 0g.

[@harrybrohan4602]

What? The gravity should grow. You would be compress in the middle of a planet (is speed=0m/s)

[@LutzDerLurch]

At the core, effectively zero

[@LutzDerLurch]

gravity has nothing to do with pressure. As you get deeper and deeper into a hole, there is more and more of the planet above you pulling you up, and less and lees of i underneath you, pulling you down. right at the centre, both are exactly equal, an you are net zero gravity.

[@harrybrohan4602]

LutzDerLurch What? No! Gravity is going to the center of the mass!

[@LutzDerLurch]

everything with mass has a gravitational effect. every little atom. The way gravity works, the math works just as well and is much easier to do calculations with, if we just assume the mass of the whole planet sits at the centre of mass at it, when thinking about it's effects on anything above the surface. Now, as soon as you are underneath the surface, there is mass above you. rocks, dirt, grampas 57 chevy convertible....it all has mass, and it effectively pulls you up a wee bit. So slightly younteracting the grav. pull of the rest of earth. If you're at the centre, half the planet pulls you up, half pulls you down...net effect = zero gravity For a diffrent approach, Look up shell theorem, to see, how at any given depth into a planet, you can basically exclude everything further from the centre of the planet as you, the wholce damn shell, as the geometry and the way gravity decreases with the square of the distance means the ent pull of the whole shell 'above' you is zero. The further you go towards the centre, the less stuff there acually is exerting a net grav pull on you. at the centre itself, it's zero.

[@jhfridhem]

This is quite GROUNDBREAKING

[@tallenrodriguez342]

jhfridhem NOOOOOOO OH GOD. NO

[@Notmuhrealname]

This joke was ROCK SOLID

[@vlogerandgamerparadise1292]

Da da tsh

[@deamontana596]

If I went to a planet I would probably dig a hole like that one for my base. I have always liked the idea of an underground tunnel network or city with one (or a few) central tunnels straight down like that, while the main bulk of the network is a series of branches at various depths.

[@CHarveyProductions]

+Darin Anderson So Zion then

[@Shinzon23]

+Chris Harvey or NORAD.

[@deamontana596]

Chris Harvey It rings a bell... what is Zion?

[@Shinzon23]

Darin Anderson The last free Human city in the Matrix films...referenced in the first matrix, showed to us in The Matrix Reloaded, and attacked in The Matrix Revolutions. It was a massive underground city that had been destroyed and rebuilt quite a few times, only, (spoiler) no one ever knew it HAD been destroyed and rebuilt

[@CHarveyProductions]

Lazurkri Also the 'real world' turns out to be another level of the matrix, designed to contain the 1% of people who rejected the matrix, to trick them into thinking they are really free. That's why there is no trace of Zion being destroyed before because they just reboot and start again.

[@nmills3]

You could use the hand drill or the voxel hands at the bottom of the hole

[@kabevo9186]

+Nicholas Mills yes you can and i did it with the voxel hands

[@MrNingaFilms]

+Nicholas Mills Hand drill disappears as well lol

[@nmills3]

rly?

[@DerpyPenguin4747]

+Nicholas Mills yes it does. I thoroughly tested this out in a bug report feature after they announced planets and said you could drill through.

[@kameronblott185]

trekie4747

[@nevercallmebyname]

they could use the center of the planet to add some of the more completely fantastical science fiction stuff in. Like every one in 100 planets has a hollow center with with some rare element to mine like a metal that allows your ship to defy gravity without being powered or a crystal that can be used as an infinite power source.

[@CrazyDutchguys]

+nevercallmebyname nah, SE is all about being realistic (without being too much of a sim). You can't defy gravity...ever. Some ore that is a very sustainable power source could work, but it should require you to have some form op top tier gear, or else it would be way too easy.

[@Spudcosmiccc]

+CrazyDutchguy In a hollow planet situation or at the core of a planet the net acceleration due to gravity will be zero. The gravity is still there, but you'll be floating about the middle.

[@CrazyDutchguys]

***** a hollow planet would collapse in on itself due to gravity and again form a sphere over time. Hollow planets are not possible.

[@Spudcosmiccc]

CrazyDutchguy It's a hypothetical situation. It can't exist but we can still model what would happen if it did.

[@nevercallmebyname]

I'm sorry for having a computer. Is it really so bad to want a little science fiction in my space gaming experience?

[@RyllenKriel]

Hahaha! Well done Aaron, I wondered when someone would try this. I'm impressed Keen allows us to drill that deep into planets. I guess 4.5-5 miles deep is far enough for an underground base to be safe from orbital bombardments.

[@constantinosladd51]

Hey Arron, i wanted to give you an idea for a hangar. Basically its a small ship with welders attached but at the same time connected to the station using advanced rotors and conveyors to link it directly into the stations storage. To do this you will need 2 rotors to allow it to point in any direction like in custom turret designs, and on that a zigzag kind of thing with rotors to allow it to move forwards and backwards. This would be soooooo useful so you don't run back and forth refilling your welding ship with stuff. Pls like this so he sees it.

[@NikolaZagorac]

The fact that the gravity is lowering is quite realistic.

[@maxireigl1919]

+Anonymous Gaming Why?

[@NikolaZagorac]

Science man. Look it up

[@maxireigl1919]

Anonymous Gaming F = G * (m1*m2) / s^2 with your distance (s) decreasing and all the masses the same the gravitational force gets stronger

[@NikolaZagorac]

Then explain how you get thrown back up after you are about at the middle of the way to the center...

[@maxireigl1919]

Anonymous Gaming Why you should get thrown back up? You enter your tunnel at a velocity v, accelerate until you've reached the masses centre then start deaccelerating until you reach the opposite surface (given you travelled through a perfect sphere and your mass didn't change) with a velocity v' that is exactly equal to v.

[@GLCxGLA]

ive been a long time subscriber of ur channel, your videos have always attracted me more and more to space engineers, i already own the game on steam, and i like it and everything, but everytime i see ur creations, it gives me the hype to build complex stuff in the game, once i go in the game, start with my invention, get brain tumors and then exit the game,... ur commentary and play shows how basic me and a couple of my friends are in the game ;P

[@wumbosaurus9121]

Back at it again Dr. Evil I see.

[@Wienerslinky]

Watched a few vids, subbed.

[@macroshaft5517]

Just wanna let you guys and +LastStandGamers know, this video is no longer accurate; not sure of when it was changed but as of october 8, 2016, i know for sure that it has changed, because i'm writing this comment on a tablet while my computer is busy proving it... :P i'm 16.92 km deep, at time of writing, and gravity is at .72g; there's been no signs of problems, thus far, and those numbers are increasing enough that i've needed to update them three times while typing this. For those wondering what i'm doing, i've got a macro pressing w for .1 seconds, every .5 seconds, while my usual .1 second rapid fire left click macro creates obscene amounts of small block warheads directly in front of me, to fall, explode, and do my digging for me. It's in what was about to be my vanilla testing world; stable branch, and the only mod in it is a speed limit remover, unlimited one by (Midspace? Mexpex? can't remember, but it's one those.) any chance you could investigate/update this further, Aaron?

[@jimmysgameclips]

This must have taken a long time! Thanks

[@Rayment1001]

Hey Aron, the reason for the decreasing gravity is that the part of the planet that is above you pulls you in its direction. So if u are in the middle u have equal amount of mass around u that pulls you in its direction so u wont feel gravity in the middle of a planet

[@simon5143]

Maybe in the future the Space Engineers developers will add heat so you can't digg depper because your ship and yourself will melt. Maybe diffrent materials can handle heat better and be able to digg depper and depper too. The depper you go and better ore quality you get.

[@honorguard7616]

Deeper

[@megapro125]

+Simon Engelholm heat would be very cool. also if a ship could melt from the reentry in the atmosphere or the player freezes to death in space if the ship interior has no heater. They could have the vents that allready are in the game collect N2 on the earthlike planet to use it as a coolant.

[@Ehnonamemoose]

+megapro125 I always assumed the suit kept you from freezing since you die without power

+Ano Namus yes it is, in planet when you are out of energy you dont die, just your tools dont work

[@JuicedPotato]

If they ever add active volcanoes w/ lava, then you will have a use for this.

[@jayc1139]

I've watched a few of your videos on space engineers for a while now, and it makes me wanna play it again haha. I got bored of it and haven't played it in almost a year because I got kind of bored trying to upkeep my asteroid base with constant mining, and I was singleplayer which got boring and lonely. Though I shall try it now that it has planets =D

[@cronic555]

Hey Arron, I'm surprised you haven't weaponized the monolith yet! Thing looks really dense...could probably do some serious penetration to heavy armor at a high relative velocity ;) I bet it would take a lot of G-force to accelerate it though assuming that it is even affected by gravity. Maybe one could use landing gears and a ship with a really long line of sight and hydrogen thrust to get it up to speed? Anyway thanks for the awesome vids, I always get super excited when I see new uploads from you! Have good one.

[@JorneDeSmedt]

Aww. So you can't build an intra-planetary rail system like in Total Recall.

[@ashtonsenko536]

Jorne De Smedt haha. I love that movie

[@vriskaserket8058]

2:40 You're joking right? this is primary school stuff. The closer you get to a planet's core the lower the effects of gravity are. Sitting at the center of a planet (assuming there was a temperate hollow there for you to do so) you'd be under "zero gravity" as the gravity of the planet is acting equally on you from all sides.

[@gazelle1467]

We didn't learn that in _high school_, let alone primary.

[@vriskaserket8058]

Gazelle Samyueru Well then your education was woefully remiss.

[@user-gf4kb7uk3p]

i never saw a school in my life which teaches anything about gravity :/

[@vriskaserket8058]

24 25 Are you kidding me? Gravity is a fundamental to any physics class. If you went to school and never even learned about gravity I'd have to say the quality of your whole education comes into question.

[@gazelle1467]

Vriska Serket Well no shit our education system is non functional.

[@Gottaculat]

It's probably to delete rogue ship parts that clip through the terrain upon impact at high speeds. I've noticed this happens as new grids are formed by a destroyed ship, and the "new" grids sometimes pop through the terrain. Since the gravity will pull everything to it, it makes sense to make a "kill zone" should the garbage collection system miss some grids that have clipped through the terrain.

[@12am55]

CONGRATULATIONS!!!! on your 700th video

[@RoqueTHEGAMER]

how about your character drill tool?

[@captrodgers4273]

underground hidden base to store stuff and ships

[@hottox8861]

Pretty good idea but how would you acces it? Gow would you get the ships out/in?

[@coach6710]

The gravity decrease is actually following real-physics. From infinity to the surface, acceleration due to gravity follows the inverse square law (proportional to 1/r^2) so gravity increases as r (which can be seen as distance) decreases. However, below the surface the gravity starts to follow a linear pattern that decreases the closer to the core you get. If I remember correctly, that is because the closer to the core you get, the more material there is around you that is exerting a gravitational force in all directions. Not to sure on that last bit, the explanation, but I know gravitational force (and thus acceleration since f=ma) decreases after you go below the surface.

[@quintoncraig9299]

Behold! Science and religion in harmony, thank you Jebus.

[@Zoms101]

Is that an intelligent KZbin comment? Has Hell frozen over?

[@xpgx1]

O.O You've build many crazy contraptions in the past .... but this? Is by FAR the most ambitious ;D

[@xpgx1]

Ambitious, not victorious ;D

[@kalemercer7053]

I only have to say it once, STARKILLER Base in Space Engineers

[@asphere8]

If you happen to clip your character through the terrain and fall to the centre of the earth (had this occur when a friend landed a ship on my head) the game becomes extremely glitchy. Gravity hits 0 as expected, but the closer the character gets to the actual centre of the planet, the glitchier the graphics become. It's the same type of graphics glitches that occur in some engines when the camera is outside of the skybox.

[@Platinum-rm4ce]

This is a certafied Dwarf Classic! Rock and Stone Brother✊🤟

[@dddddd2002]

They have been added this "disappear" thing. In first time i have played with planets, i did drop warheads down to my hole, and i've been reaced the "center". It was the empty sphere with strange gravity in it - thats all i can remember

[@siegesquirrel42]

Your warhead strategy is not unique to Space Engineers or a new idea - they've been doing that with TNT in Minecraft for years.

[@AtruePawn]

why? thats such a waste....

[@IrritatedBear]

Of course gravity decreases the further you go sown

[@IrritatedBear]

+Pan kurczak that's irrelevant, if you went to the centre of the earth, gravitational force will equal 0

[@mystagogue71]

+Pan kurczak Actually that IS how gravity works. As more of a planet's mass is above you, the less there is pulling you down. This isn't true for Earth only because Earth's density is not constant--but that has nothing to do with the physics of gravity. If it were the opposite, and most of the mass of Earth was at the crust, if you went down far enough you would be pulled back up.

[@lorenzvo5284]

+Manofiron norifonoM Thats exact

[@mortisCZ]

+Pan kurczak I can not agree with You. We consider gravity to work like that to ease our calculations but any given (well You have to make exception for some theoretical particles but protons, electrons even photons are o.k.) particle has its own gravity which means that center of mass is just a point where all those forces are in balance. If You place yourself (in shape of perfect ball of matter :-D ) in center of mass of huge perfect hollow sphere made of lead, walls would try pull You to them but all those forces would negate each other. You might imagine it as static version of a Lagrangian point. :-)

[@zensationalist]

+Pan kurczak Took long enough to find, but I'm glad the comment chain didn't devolve into this: gifsoup.com/view/2382683/angry-mob.html

[@Deresius17]

Hey, I don't know if you know this yet, but you can get to the center of the earth with voxel hands, and dig a tunnel just as wide. If you hold the button, you can usually fly straight ahead through the center at max speed. After the hole is cut, any thing can go straight through. It is 0 gravity at the center, and you can make really cool little orbits in the core with stones and things.

[@wolfyboy]

that was pretty awesome! thanks! :D

[@themikead99]

Aaron, you have stopped nothing. Drill through the opposite side of the planet and meet in the middle.

[@jasonrtz]

themikead99 the planet is 220 kilometers wide. He only made it 7000 kilometers. He still would not meet in the middle.

[@Ghostread]

7000 meters not kilometers

[@xflushestmean93x54]

I have a good idea, why don't you make a space elivotor?

[@xflushestmean93x54]

Elevator*

[@FEFELAND]

+Hayden Murphy did you see the latest patch video on the space engineers channel? someone did it and its awesome

[@TheAsylumCat]

+Fefeland Do it anyway.....

[@chuckydickens7258]

Aaron, now with this info, what if you dig, straight down, on the side of a planet, like, 7km north of the equator and dig down 'till you pop out 7km south of the equator? would that allow for a 14 km tunnel to ship goods through? How far from the equator could you go to still have that work? (assuming it works at all)

[@89josephje]

At the moment, you're better off using voxel hand to dig a hole through the planet. Its a pretty cool effect if you have a high speed mod on. Once you get the the center of the earth like planet, the screen goes white, black tears start to grow and eventually the screen goes black, and everything becomes lighter as you approach the surface of the other side of the planet.

[@IgorDz]

Can you destroy a planet then? Like trim it as much as you can until you have a little asteroid

[@noxabellus]

I imagine the amount of save data that'd generate would eventually halt your efforts

[@maccaronich]

Gravity will be 0 at the bottom, that's how real life works too

[@harrybrohan4602]

Vinn_mobile Stupit? Earth is flat. Chemtrails! Ok just kidding. Gravity pulls you to the center of the mass. If you are in the center of a planet, incredible gravity from every direction would affect you. You will be simply compressed.

[@jacopofantuzzi4334]

you can place some gravity generators along the tunnel sides to mantain the ship centered. Or wheels + suspension. Even a system that can balance the ship perfectly vertically (with gravity generators) would be enough to avoid collisions

[@dr.birbmd7266]

I like the idea of an elevator of sorts like in the new version of total recall, I wonder something Aaron, could you (will be a pain) some how get to the opposite side of the planet and dig another tunnel to meet it?

[@Skythedragon]

planetary annihilation: Ragnarok dig to the other side with this thing, and make a quick-travel device to get to the other side of the planet

[@Graystripe000]

+Skythedragon Did you even watch the video? He already covered that... You can't do it.

[@Skythedragon]

I watched the vid without sound, cuz I was listening to music

[@BirdsonBranches]

+Skythedragon So you are trying to add to a conversation without having listened to the conversation? Person A: Man, did you see the game last sunday? Person B: Yeah! Did you know it was the player's birthday? Person C: I like ketchup!

[@BirdsonBranches]

you are person C. Try to be person A. A is a social kind of guy.

[@faressdiri9857]

lol, love it!

[@perigrin2115]

I actually do know what happens at the center of the planets, as a friend of mine once fell through the surface of the earth when we were trying to reach it with huge amounts of explosives. I convinced him not to exit his game, and we found that you can fall through the weird void that exists until something is mined until gravity drops to around 0.1 G, at which point you freeze up and the game spasms out. We have not been able to replicate this yet, but it is interesting.

[@billyuno]

Just out of curiosity, have you considered going around to the opposite side of the planet, and doing the same thing to see if you can somehow make your tunnels meet up in the middle? What about going around the core? IE: Dig sideways and down until you've marked out the boundary of where you can no longer dig?

[@SnicerTenu]

Actually it does make sense that the gravity would begin to drop the deeper down you go. I believe vsauce had a video explaining travel through the center of the world, it's all mass based and once you go down so far you'll actually begin to slow up as you approach the core. This is because the further down you go the more mass is going to be above you, so once you get to the core (ignoring the pressures and heat) you'll probably just float there. Good job on the dev's part for thinking about that and doing their research.

[@artemisf125]

For anyone that's still curious: the gravity goes to 0.01g around the planets core (I assume 0 if you stand perfectly in the core) so you do just float around. Other than that there's nothing exciting down there. The lighting does go a bit strange because its day on one side and night on the other. And if you place a space station cube it seems to get a strange light in the corner that's right in the middle of the planet but I dont know what that is.

[@edkopik]

as you go under a planet there is less mass bellow you and more bass above you, so the gravity splits with part of the mass no pulling you up, so you have a smaller acceleration

[@professorthree]

Since planets are spheres, what would happen if you went around to the other side of the planet and dug your way toward the end of your first tunnel? Could you meet them in the middle or can you just not dig a tunnel long enough at all?

[@TheVergile]

figuring out the actual gravity acting on a drill going to the core of a planet is quite complex. There are three main considerations: a) the gravitational force due to the cores mass will increase, since you lessen the distance to the baricenter b) the deeper you got, the higher the amount of mass, which only contributes a small percentage towards downward force or even counteracts it, since it is "above" and "beside" you c) a planets mass isnt distributed evenly throughout its volume. So realistically speaking gravity would increase for a while, then drop until hitting perfect equilibrium once you reach the center of mass. All the way through youd experience fluctuations.

[@MineActivityHQ]

When planets first came out, using that weird drilling downwards bug where you fall through, I ended up slingshotting back and forth between the inside of a moon. When I got to the center there was no gravity, but because of the speed I was travelling I still got swung through it and to almost as far as where I entered the planet, sort of like a pendulum.

[@universefactsitaly-jack9287]

This is my favourite video ever

[@EmanuelMay]

Haven't seen it mentioned yet, so here it goes: Lower gravity deep beneath the earth actually makes sense, because a lot of the planets mass will be above you, when you are deep underground. As gravity comes from mass, this means that the earth above you starts to get so massive, it pulls back at you, so you would actually feel less gravity deep below.

[@Fusurugi]

The furthest down we drilled so far to my knowledge is 12066m (kola peninsula on russian soil), reaching 180°C on the bottom. Studies revealed through meassuring weight that gravity below ground is actualy lower as the mass above increases.

[@Avatar555555]

I've got to the center of earthlike planet, it took me 7 attempts to design a mole that works by gravity and not being damaged by bumps, no mods used. It's got to the center over 9 hours of drilling and got stuck in the center, because of zero gravity. It's actually was wobbling for about 10 meters up and down like a yo-yo.

[@Riftwalker_hpf3]

aron i think it would be a cool idea to have some bases connected by gravity trains(trains that go through tunnels that go through the planet in straight lines so that the train can essentially fall to its destination and uses mostly gravity for its acceleration and deceleration) you would just have to make sure to angle the tunnel so it doesn't hit the core

[@richfiles]

Is this a physics range issue, or could you drill an arc around the core. That, in and of itself, would still be an amazing feat.

[@thefiremarshall2727]

Would love to see you try this again but heads up when I tried to do it after about 5 km down I had to I had to restart the game and I lost my save

[@willgrasser1392]

On earth as you go farther down into the earth the gravity becomes less because you are being pulled up by the matter above as well as being pulled down by the matter below (you are also pulled by the stuff beside you) so when you reached the center of the Earth you would be truly weightless because all of the gravity cancels itself

[@daikhairai7194]

i use a combination of Long pistons gyro scopes thrusters and a rotor drill head allow more precise control in a hands free/autonomous way, my problem is that when i left one on apparently if there drilling going on for and extended time with out a player there you'll end up having a chance of the collision physics on the terrain glitching through and allowing something to pass through the ground as if the ground wasn't there. i fell through the planet you know what i did then? made a space station at the center of the planet cause why not?

[@TruthTheAntiVenom]

i think that the warheads were being scrubbed but the auto trash removal due to the distance from arron(i don't think that the spectator cam counts). If he moved his body closer he may have been able to continue. at least until he runs out of ram and CTD. and I did see the block disappear after he dropped down, but I think that is a case of blocks falling though planet.

[@001sharpshot]

Honestly I would dig down to create a under ground base with a like mini out post looking thing on top to disguise it or build into a mountain or similar. You could make a pretty extensive tunnel system with that.

[@wolfsgamingonline]

The gravity going down is actually realistic, when you get closer to the core the gravitational pull from the other side of the planet gets higher and in the middle it balances out. thus making you weightless. (Sorry for my bad English)

[@Skillfulist1]

Can totally see the developers adding a molten core to explain that deletion process.

[@johannes3057]

In one of the trailers for Space Engineers they digged throw the whole planet with a drilling ship.

[@marcusrumander6420]

What happens if you dig along the same line but from the other side of the planet? How far of eachother will the ends (bottoms?) of the holes be?

[@jameshuke354]

Cool idea, build a super well defended criminal base inn there. U could have turrets and blast doors in shaft

[@demondeity9816]

the gravity going down makes perfect sense ,gravity doesn't pull you too the center but to mass ,once you go down far enough the gravity of the mass above starts pulling you up so if you got to the center you would feel the gravity from every point around you ,making zero gravity

[@bikutoso]

Building a underground base at that depth would certainly keep you safe. Only you would have required to build a lift system to get people down. and it would probably require a stair case that reached the surface and was hidden in a cave in case of emergencies.

[@CountJeffula]

The gravity decreasing with great depth is wholly consistent with real life physics. At the center, there is a lot of pressure, but you are surrounded by mass in all directions, so you won’t accelerate in any direction. At the surface, there is only mass below, so gravity is higher.

[@Vindictator1972]

There are several reasons you would want to dig to/ through the core. Several of those reasons involve Bases. Some are Hangers and Ship Yards. And Lets not forget about SECRET BASES. And some good old fashioned Mining.

[@xKillerfeexDD]

whats about this plan: using an anetta in the whole then on the other side of the surface to see that distance and maybe drill from the other side??

[@DavisonIncorp]

Marek! you promised we could dig straight through!

[@kabrozkabroz]

@LastStandGamers it has to do with atmospheric pressure. as you dig further down, the pressure of the atmosphere is weighing down on you less. So it's not necessarily that the gravity has gotten lower. It's getting higher. but now the earth is holding up the atmosphere, instead of your shoulders, as an example.

[@elijahhmarshall]

idk how many of the comments you guys read, but i have a cool idea. What would happen if you used some sort of level editor to delete the whole planet except the middle part that deletes everything it touches? Would the gravitational field still be present? If so would that basically make the planet a space engineers black hole?

[@SgtGrave]

Did this on the alien world. 7 KM deep had the same deletion results. To get to the center, where it does hit Zero G we switched to the voxel tool in creative and simply deleted the ground as we fell for about and hour and a half to we reached the center.

[@THECHAOS111]

If you just use voxel-hands all the way to the center in creative it goes to 0 gravity, i was trying to hollow out a planet and do a sort of hollow earth thing with an underground city sized cavern and a single hidden exit and i came across this same problem of the blocks deleting.

[@NiquidFox]

To answer your question, yes gravity decreases as your depth increases (on Earth anyways). Eventually your gravity would be 0 at the core, due to a net gravitational force of 0, as all forces begin to point outwards (from varying masses on the surface/away from the core) and thus, zero gravity

[@macgabhann1108]

+LastStandGamers ive drilled manually in creative down to 0.3 G then when i keep going the gravity started going back up so im sure we could do a tunnel all the way through the planet if we wanted to but the center would probably have to be done by hand.

[@bubbles69138]

7km down... you could build one hell of an underground base with that!!! And being so deep, orbital bombardment would take forever to blast through into the base :D

[@danielconley911]

Would this work better with that ship you featured that shot through the asteroid with all those crazy beams

[@ergpedrowvski5712]

i've done it in vanilla yesterday so i was surprise (with a ogive auto builder/droper) just one more step and you could did it, the background of the hole is just a texture, you can cross it and just fall for ever in the void :D

[@BT-2013]

A true scientific experiement. "Hey, what happens if we do this?" "Idk, fuck it, let's do it!" Great video mate.

[@Anubis1101]

its funny im actually sitting in a mining crawler right now. i designed it poorly and it started to point further and further down so i figured, why not see what happens? i just passed the 1km mark a few moments ago. i dont even need to drive it, its pretty stable as it is. i might leave it there overnight and see how it looks in the morning.

[@emperorofthemankind7396]

Love his outro music so much.

[@Mikowmer]

Hmm... The gravity dropping is what would actually happen as you get closer to the core of a planet, because of the fact that there is enough mass behind you to counter the gravity of the mass in front of you. I commend the devs for actually getting that to work.
