It's amazing how resilient KSP is. Someone on the KSP subreddit showed an image taken just before a crash after some crazy modding, and the altimeter read "999 999 Y".... That's yottametres. 1 Ym = 10^24 m. I think this makes the observable universe look tiny. AFAIK KSP doesn't have all space available at once (because otherwise no computer in the universe could handle it), rather space is generated in "blocks" as and when an object in KSP interacts with it. The crazy modder traveled through space so quickly that the space couldn't be generated and stored in memory fast enough, which lead to KSP asking for illegal memory access - BOOM. IT CRASHED. But this is IMO a great example of KSP's durability.

I'm mildly disappointed that KSP doesn't take special relativity into account. Not that it's likely to be relevant to any craft legitimately built in the game, but.. still.

[@RurikLoderr]

+YouCubed22 At the velocities present playing the game without cheating for infinite fuel or using mods, relativity has such a negligible effect that it isn't worth adding anything related to it. You've got to be going damn near .5c(149,896,229 m/s) before you start really noticing anything. For example, at .5c the apparent length of the ship due to the lorentz contraction would still be 86.6% of its true length. At .1c, which Scott's ship almost reaches in this video, the apparent length of the ship is still 99.5% of it's true length and a day of travel on the ship is only equal to a day plus about 20 minutes or so on earth. So.. again.. no reason to make those changes until they add interstellar travel and technology that doesn't exist.

[@petroleus]

+Matthew Hennes Special relativity would be fun, but has only a very small effect in the end. The effect of gravity, from general relativity, is a far more dominant effect when the difference in gravity is appreciable (such as between an on-surface object and an orbital/deep-space object). Sadly, even so, the only thing you would notice, is a difference in the on-board clock and the on-ground clock, since the whole point of 'relativity' is that everything is relative, and you simply can not notice it, or even measure it in any way, other than that it is different from another observer. Really this is the founding principle of the theory, so there's no way around it.

[@0xf7c8]

+YouCubed22 It would not take much extra code, as you said. You only have to take linear Galileo transformation and replace it with lorentz transformation. But this calculation is a bit more dificult. The machine can do it without a problem, but if you have to repeat that for every particle moving in the game a lots of times per second and transform between every particle, and doing this only to get that the contraction of time or space is les than 0,005% at most, its not worth it.

relativity is like flying plane and sound wave . except( with relativity ) we perceive sound wave as a light. in front of the plane sound wave is compressed and behind is decompressed so that explains time dilation . so the relativity on it's basics is misleading(as you can see in video above) . so what he actually tried to do is to make the plane's sound wave to compress infinitely(singularity) and decompress infinitely(across observable universe) so the time dilation could be infinite .

The only hit box in the whole game is the small patch of land below the craft which also doesn’t move, and everything else are just skyboxes. So in fact every craft you build doesn’t move at all.

i don't think so. at least not in any way useful in KSP. gravity assists inside a solar system help you change your velocity relative to the sun. so a slingshot around the sun could only provide a boost from an interstellar perspective, but i'd expect that to be far beyond the scope of KSP (and it's velocity readings). edit: you could of course take advantage of the oberth effect which would probably be quite significant near the sun.

They've gone to plaid!

[@jaredhardegree8377]

I've had pieces travel at the speed of light out of the solar system after an explosion on Kerbin. It happened not once, not thrice, but twice.

[@notgreg123]

Not three times, not FOUR times, but two times

[@Thewaterspirit57]

That number is about 100 + the length of the universe. way over 9000.

[@VectorJW9260]

Is lightspeed in KSP a tenth of our universe’s lightspeed

[@b.g.1764]

danny reached almost 7 times the speed of light after he crashed (I think) in Jool! :D

[@brysonfrank6476]

Jeb's face is fun to watch

[@mrmoore2050]

I have come upon one of the ancient KSP tomes...

[@Seviexe]

I was expecting a dull Kerbal video, maybe slightly quirky at best, got one of the most original explainations regarding the speed of light barrier I've heard.

[@MBitzDE]

so i am at 3:15 now and i wonder: why is he using 9.81 m/s^2 for the gravitation, while the video shows him flying through the Space where it actually is way smaller (i'd guess it is even smaller than 0.1 m/s^2 which has a huge effect) can someone explain that?

[@scottmanley]

It's a conversion factor used so that scientists working in Imperial and Metric would agreekzbin.info/www/bejne/pJ_MpIebjrF_ndU

[@madwomansinsight]

+Scott Manley commenting on a near 4 year old video, nice remembering.

[@harryrushton5270]

Scott manly turn a savage when you question his maths

[@thatfinnishguy1571]

What the ****/pug does smart A.S.S mean

[@Dcook85]

Coming from a person who, when first playing KSP, launched a rocket into space, and pointed it directly at the Mun and thought he could get to it by just blasting "towards" it. Yes I can attest Scott is in a different league entirely than I am.

[@elireloaded]

Yet I can make something go the speed of light with a "D" cell battery and a mag light.

[@blue_kobolt1785]

Light often travels at the speed of light. Funny how that works...

[@loopysausage]

:( The moment you realise that your secondary school didn't give you a chance to learn this. Basically, School didn't give me the option to choose physics when I really wanted to learn it. -_-

[@cameronmcallister7606]

But thank your lucky stars you learnt Pythagorean theorems!

[@AdrasHoriaGaming]

loopysausage go to a university of physics, easy peasy

[@loopysausage]

Adras and Horia Gaming Are you sure it's that easy? The closest thing to physics I've learned in school was simple algebra. :/

[@AdrasHoriaGaming]

not rly but if you are really passionate you can learn it very fast, you just need a good professor

[@BladezAndrew]

Same here.... My school changed its curriculum so instead of having physics they made the people in my grade take biology..... For 3 years in a row "LEARNING" THE SAME FUCKING SHIT EVERY YEAR!!!! Oh yeah and they changed math as well..... I never had geometry also because I've always been in classes 1 year up and with the change, that was impossible...... So yeah thanks Obama! So when I started to try to play Kerbal Space Program..... I had no idea... Not even the slightest clue.... What anything meant! :D Luckily it gave me the initiative to learn that stuff myself! But it's still ridiculous that it seems like school is a giant fucking joke -____-

[@sumdumbmick]

so based on this, with a mass of fuel roughly equivalent to Mimas, and an ISp of 800,000 you could accelerate a classic VW bug + passenger to c.

[@Spartan536]

There are 3 other inherent issues that people often overlook when it comes to reaching or attempting to break the speed of light in raw speed (not Warp). 1. Deceleration to target - you briefly touched on this, using conventional methods it would take just as long to decelerate in a straight line and that is assuming that your velocity is not affected by other gravitational forces in the vicinity. 2. Sensor detection of spatial bodies..... on the earth there is a saying for pilots like me, "speed is life, altitude is life insurance". In space altitude is relevant to an extent, however say you make it to 90% light speed, are you 100% sure your sensor data is correct or will you suddenly cease to exist because you hit a rogue/undetected spatial body, that would take your velocity to 0 m/s in microseconds. 3. How slow is the speed of light? What, light slow, nah.... well yeah, it is slow in the grand scheme of things in the universe and even in our galaxy. From one end of our galaxy to the other it takes light around 1000 years to travel that distance, either you are about to sleep longer than Rip Van Winkle and become the oldest human in history with some super suspended animation technology or you and your entirely families genealogy will be so different no one will recognize you or even have a DNA profile similar to you. Light is slow, and even if you went faster than light speed and managed to keep #2 above in check there is a special relativity clause that states anything that goes faster than light is incapable of slowing down below the speed of light, so have fun with that. This leads back to the good old "Warp Drive and the Alcubierre Drive" solution where you enter a fold in space time to cut your travel distance from hundreds of trillions of miles to potentially a few miles or whatever distance you want or can sustain with the drives power. I would like to point out 1 theory I believe in, and that is that light is not the fastest speed, it is a speed like the sound barrier but with much more complicated issues. The fastest speed in the universe is the speed at which the universe itself is expanding. How do you know or theorize the speed of universal expansion? If you take 2 spatial bodies that are moving away from each other and compare that to other spatial bodies exhibiting the same pattern but at different distances you will find that the further they separate the faster they separate. In fact some spatial bodies have already been calculated and observed to be moving away from each other at FTL speeds. This does NOT mean the planets are moving faster than light, its just their rate of "repulsion" to each other is faster than light. This observation works with the theory that at the very edge of the Universe, the composition that makes up whatever the Universe is (this is currently called Dark Matter and Dark Energy as we have no clue what it is comprised of in basic terms) is expanding faster than light as we will never see the edge of the universe for that reason, and the universe can do this because it has infinite mass.

[@techHmrk]

+Spartan536 Its way more coplicated than you present.

[@naphackDT]

+Spartan536 About point 3: There is relaticistic effects fixing that specific point for you.

[@ibot9776]

Try not to type that much. No one will read it.

[@naphackDT]

***** But space does expand all the time. How else can an infinitely large universe keep expanding?

[@techHmrk]

***** My english is not so good, but I have no idea what you are talking about :D Of course space is expanding, thats given and we can measure it. Only we dont know why. It has something to do with "dark energy", but no one knows what is it.

[@Fuguerrero]

i know how,hit jool really really fast with phisics warp and boom you are 15x the speed of light

[@raikkappa23]

150000x*

[@Soliy87]

My Head Hurts :)

[@hypochondriac3194]

I got 10x the speed of light with no mods, i hit the moon at an immense speed which launched a radial parachute casing (parachute already used) which has no mass/drag after begin taken of rocket so it launched into interstellar space at speeds past light

[@gabrielmaisonet2843]

Liar.

[@hypochondriac3194]

Truth tho

[@zombievideos247]

Prove it. It's impossible and unfeasible to reach faster than light without a K-Drive.

[@hypochondriac3194]

How do you think light gets to the speed of light? a K-drive? it uses the fact that light doesn't have mass or drag. My para-pac was massless and dragless, and had force propelling it. As for the theory of relativity, it wasn't factored into KSP

[@zombievideos247]

Andloo Yunty How did you make your Parachute not have any mass?

[@andymanson3836]

for all of you people that don't know these two parts of what he said in the video, here is it explained:Everybody knows about Bytes, Kilobytes, Megabytes, Gigabytes, etc. Well the Petabyte is I think the second term after Terabyte. And remember:Kilobyte=1,000 Bytes.Megabyte=1,000,000 Bytes.Gigabyte=1,000,000,000 Bytes.Well, a Petabyte is 1,000,000,000,000,0000 Bytes (1 Quadrillion)which is nothing compared to the Yottabyte which is about 1 or 2 terms above Petabyte, when the Yottabyte was first thought about/discovered, the storage unit needed to fit all of the data would be as big as half of Rhode Island's size.As for the googolplex, a googol is a 1 with 100 0's behind it, and a googolplex is a 1 with a googol of 0' behind it. Go to, I believe the website is, to find out how big a googol/googolplex is, go to Googolplexia.com

[@nautalyst2996]

Or you could joust with Jool and go 8.5 times the speed of light...

[@CanyonF]

But that's not realistic. Although why not?

[@nautalyst2996]

Canyon Fuchs Why? Cause KSP, thats why

[@CanyonF]

JimtheCreeper Thats a great reason!

[@ThePizzabrothersGaming]

for i thought he was close, then i took a closer look and he was going a 10th of the speed of light 0_0

[@g43654]

I'll just zoom all the way out and click on two distant galaxies on either sides of my screen. Ha, beat that light!

[@mwbgaming28]

how to beat the speed of light with only a laser pointer shine a laserpointer at the moon and flick your wrist congratulations you just moved light across the moon faster than light

[@mwbgaming28]

you must be fun at parties

[@temmie621]

All it takes to accelerate to the speed of light in kerbal space program is just a tiny physics glitch

[@zarokaleon4974]

I wonder what would happen if you crashed that into a moon

[@TheLiamIanto]

in ksp i think you would go through it, in reality i think we'd have a problem with our waves afterwards xD

[@GeneralDolphinMedia]

Liam Ianto actually... more like a problem with our entire solar system

[@VelociraptorsOfSkyrim]

JimmyJamesKirk The Moon really only affects the tides on Earth.

[@GeneralDolphinMedia]

well... if something of that speed hit anything at all... it would cause the atoms to split and result in the moon going super nova

[@VelociraptorsOfSkyrim]

JimmyJamesKirk Not exactly. If anything it would be a very large Nuclear Explosion. Earth would be sterilized and burned to a crisp but the rest of the system would be okay. Remember, light particles hit us at the speed of light everyday.

[@davidmolnar975]

[@pauljs75]

Thats why reactionless propulsion (like the Em-drive) is pretty interesting if it's legit. You're no longer worrying about throwing that ridiculous amount of mass out the back and you're not hauling it around either.

[@g79support10]

Em-drive is legit, i saw that nasa tested it in a generated vacum and it worked, the shot a laser trought it and calculated the time it took for the laser to travel from the start to finish aannnnd it was faster than light.... So yeah... Space warp

[@thomasfudge99]

That's when you realize the magic of dark matter

[@orestasvanagas9572]

dark matter is everywhere even in your body . but i will make more sense if i rephrase the phrase. your body is in dark matter . but why we don't tear apart? because our body atoms are more closely related than the 1000 million light year apart galaxies. by the way scientists don't need to create it at all because dark matter is always around us.scientists should pay attention how to contain and compress it to use it in alcubierre drive

[@orestasvanagas9572]

+Rúben Pais because it do and there is no explanations only observations

[@Mernom]

+Orestas Vanagas how does dark matter ties to the warp drive? Last time I checked they were two diffrent things.

[@jedimann7468]

here is something I found... neat... Matter is the stuff you are made of.Antimatter is the same as matter in every way, looks the same, behaves the same, except its particles have electrical charges opposite to matter. E.g., our electrons are negatively charged, whereas a positron (an antimatter "electron") is positively charged. The positron is the "anti-particle" of the electron.When a particle meets its anti-particle, they "annihilate": the two particles disappear, and gamma photons are released carrying off their energy. For this reason, should a lump of matter touch a lump of antimatter, they would annihilate, and a giant explosion would result because of the huge energy released (E=mc^2).Matter and antimatter are definitely related: same thing, but with opposite signs. Twins, but opposites.It is not clear why, but it seems like there isn't that much antimatter out there, more like trace amounts. Definitely not as much as regular matter as far as we can tell. This is puzzling to physicists and cosmologists, because you'd expect the Big Bang to make roughly equal amounts of matter and antimatter. Scientists agree that the paradox of "excess matter" will advance physics even further once it's solved.Dark matter - we don't really know what it is. It's not even sure it's "matter" in a conventional sense, or related to it in any way. We just know that galaxies are rotating in such a way that indicates there's a lot more mass out there, but it is mass that we cannot see and cannot be accounted for in the usual ways. Hence the name "dark" (as in invisible) matter.Dark matter doesn't seem to interact much with regular matter, except gravitationally. Right now dark matter could be passing through you and you wouldn't notice. Dark matter also does not interact with light, so you can't see it. It doesn't seem to interact much with itself either, so for this reason dark matter cannot form "clumps" such as planets or stars. Instead, it probably exists in a diffuse form. Bottom line, dark matter interacts pretty much only via gravity.The shape of galaxies is a proof of the existence of dark matter, and is a result of the interaction between matter and dark matter. Without dark matter, galaxies would be much less massive, and the outer parts would rotate much more slowly compared to the center. Due to dark matter, galaxies are quite massive, and they rotate almost as solid objects - the outer parts rotate approximately as fast as the central parts.Estimates vary, but it seems like there's something like 5x to 6x more dark matter out there compared to regular matter.

I know he used cheats and I'm probably wrong but wouldn't be impossible to go the speed of light since he has mass and light doesn't. But like I said I'm probably so if I am wrong can somebody tell me.

[@andyyudiche]

vivagable12 Did you take into consideration of the fact that he will most likely be using a stage rocket that loses mass as it goes?

[@retrofan42]

Hey Scott. I really enjoy your videos about KSP. I have been using that "other" great space flight program for PC computers (Orbiter) simply because mine did not have at least a dual core processor (it's kinda highly recommended) but I just got a new system so hopefully I will be able to try KSP myself. If you have ever used Orbiter, that will allow you to do faster than light speed with the stock program, but you won't be able to control where you go. There is a quirk in the program that renders the Sun as a 2D object instead of a 3D object, so if you try to land on the Sun, you instantly get sent in "nether" space at speeds exceeding the equivalent of the Star Trek TOS warp 3. That's kinda fast. :-)
