The Science of Mass Effect - Dark Energy and Worm Holes - Extra Credits

Wanna learn more about 80's sci-fi? Please go support the "In Search of Tomorrow" documentary over at www.kickstarter.com/projects/...
Thanks to the help of guest writer and astrophysicist Erin Macdonald, writer of the Science of Sci Fi (adbl.co/2yRxVWK), this Extra Credits is going to be a little unusual. Have you ever wondered how rooted the science in scifi really is? Well in Mass Effect's case, there's actually some very solid ground. We'll be talking about how the Mass Effect relays work and what the theoretical working behind element zero is, and how, if we could replicate those effects using real elements like dark energy, we might also be able to date some aliens. ... What do you mean that wasn't the point of Mass Effect?

Mass Effect has always been my favorite science fiction setting, largely because of its very grounded scientific explanations of its workings with Element Zero. Their explanations of FTL travel, artificial gravity, shielding, biotics, weaponry (how their guns shave off tiny slivers of a material), all their technology, and of course the wonderful characters and incredible lore of the various races, etc., just makes it so fantastic.

@@freakymoejoe2 Space Opera has nothing to do with hardness of Sci-fi, it's just a subgenre that focuses on epicness, war, politics and romance in contrast to sci-fi that focuses on social satire and application of technology like the works of Ray Bradbury, H.G. Wells or Phillip k. Dick. There is space opera on the harder side, like Mass Effect, which tries to explain the physics, and there is fantasy IN SPACE like Star Wars with knights, princesses and samurai dragons in a breather mask. Any sci-fi that tells of epic heroics between bedding bleu-skinned babes and space wars on a large scale is Space Opera by default.

Maybe no entirely on topic, but Subnautica had this effect on me. Both the underwater terrain and creatures are (for the most part) portrayed and described in such a way that you get the impression they could really exist. As for the terrain, I often find myself looking at it and thinking, "hmm, I think I know how this landscape formation came to look like this", as if it had really been formed by tectonic shifts or volcanic activity over countless millenia.

[@danvzare6201]

And then there's Sci-Fi that makes you amazed that the writer managed to predict rocket launchers, drones, and even online shops, all before World War 2. Armageddon 2419 A.D. is a truely incredible book. A good read too.

[@dbrokensoul]

I remember being blown away by their Codex about Mass Effect itself and the Eezo. The idea is really sound and makes a good sense. I'm really amazed by the fact that simply by inventing one fictional Elements they could make the whole space society exist. Telekinesis? Eezo. FTL travel? Eezo. guns? Eezo. Artificial gravity? Eezo. And it's not lazy writing too, since the explaination of eezo does make sense for all those application. I tip my hypothetical hats to the writers who came up with the idea.

[@dajolaw]

6:30 - I'm assuming this is an intentional attempt to avoid spoilers and not a mistake about the lore.

[@templar684]

Considering the depiction of prothean is from me3, you can assume it is to avoid spoilers and spending ten more minutes explaining the plot.

[@TheDakkaman]

dajolaw *SPOILERS* . . . . . Regarding the “Protheans did it”, to be fair that is one of the better twists in the first game, so them not wanting to spoil is acceptable since it doesn’t end up affecting the mechanics one way or another. Regarding the “it’s wormholes” hand-wave, from the perspective of someone unfamiliar with the series (you know, tasteless heathens) the mechanics of the Relays are close enough to a wormhole that using that common knowledge concept is much faster than an explanation that would tack on at least another minute and likely a few expensive pieces of art, so the shortcut is understandable. Amusingly enough though, this video did make me realize that the mini-relay from the first game doesn’t makes sense without wormholes, unless there was somehow a straight line from the surface of Ilos all the way to an atmospherically-sealed point on the Citadel, which means Shepard was already some bullshit kind of luck for that alone.

[@TheDakkaman]

Joshua Chambers As Juan Paolo says, you are correct in that there is a tunnel created between relays, but in physics and sci-fi the term ‘wormhole’ normally only applies to such a connection when the tunnel itself exists outside the normal fabric of reality, so the fact that ME ships (and that one badass tank) travel through every single inch of the intervening space is generally considered to be a disqualifier for the title of ‘wormhole’. That said, the concepts are similar enough that the term is useful for the sake of avoiding a digression like this one.

I'm so happy extra credits is doing Mass Effect stuff, one of my favourite video game fictions of all time.

[@talideon]

Beside Eezo, the other "big lie" of Mass Effect is the idea that there's a real thing called "negative current". There isn't. The closest you could get to this _maybe_ being a thing would be if the 'negative' and 'positive' bits referred to the charge carrier, with one referring to electrons and the other to positrons, but then you're not longer dealing with an _electrical_ current.

[@MoiMagnus1er]

An easier explanation would be to have Eezo be a profoundly asymmetric particle, that with all the Eezo particles naturally aligning themselves in the same direction and orientation when near each others, like small magnets. Then "negative current" and "positive current" would just be "current upward" and "current downward" with respect to this direction.

[@TheDakkaman]

Considering how the Relays aren’t a thing in that one, it’s understandable from more than a ‘corner of shame’ perspective too.

[@tehbeard]

Don't the mass relays work as an upscaled version of a starship eezo FTL core, not as wormhole generators? (something about them generating a mass-free corridor between the relays? ) I'm not sure how the lore/fluff deals with interstellar medium or larges masses on the "flight path" though.

[@swordsman1_messer]

Got Mass Relays wrong. They aren’t wormholes; they’re literally mass drivers that massively boost the acceleration (and thus travel distance) of ships in the universe. The cutscenes used when traveling between system clusters in game clearly show the relays pouring energy into the ships. So, in actuality, relays act like supercapacitors, adding additional negative charge to ships (there are civilian shuttles that are FTL capable but would certainly not have power generation on par with military ships), and allowing them to reach FTL much easier.

[@Gala-yp8nx]

I’m Commander Shepard and this is my favorite video on KZbin.

[@ViolosD2I]

What I found even more remarkable than explaining all their science fu with the introduction of the mass effect was that they also thought realistically about space battles. From stealth being about masking heat radiation and the biggest issue for combatants being to get rid of heat in "cold" empty space to the fact that you need to force engagements near important targets because you can't track or intercept anyone when moving at relativistic speeds.

[@andrewgutmann9432]

3:28 No, nuclear bombs do not work this way. They are fusion/fission reactions, not matter annihilation reactions. They release the nuclear bonding energy (the energy equal to the rest mass lost when protons and neutrons bind) of nuclei, not the entire mass energy. That would require antimatter, and would be orders of magnitude more powerful.

[@placeholder1308]

i think he meant that a teaspoon of mass contains as much energy as a hydrogen bomb

[@Darasilverdragon]

I'm fairly sure they know that - the amount of fusible material in a thermonuclear bomb is considerably more than a teaspoon, or whatever they said in the video. That teaspoon measurement is intended to represent the aggregate mass lost by all the quadrillions of atoms participating in the reaction process - because at the end of the day, you are in fact seeing particles lose some small fraction of mass, and getting more energy output than the strong nuclear force can account for. There IS mass-energy conversion going on in fusion and fission.

[@Dr.CaveCurinas]

@@placeholder1308 Assuming Uranium as the material in the teaspoon, this would give a total mass energy of ~8.56*10^15 Joules

[@yalelingoz6346]

Great video It feels like Erin Macdonald is explaining about 50% of the reason I fell in love with Mass Effect, that under the fun space opera is solid speculative fiction. Starting with a few changes in reality like "what if Eezo exists and works this way" and following it to it's conclusions: FTL travel; personal and ship shielding; the Mako; artificial gravity; guns being just mass drivers (so the ammunition is just a block of stuff, and the amount used to small as to be negligible over the time period of the game); heavy weight drones.

[@Dramatic_Gaming]

The 'glued-down bowling ball' analogy is actually a good description of how the mass relaus work rather than calling them wormholes. The relays create tunnels of negative mass space that ships can fly through at FTL speed rather than simply teleporting from one point to another. It's pointed out repeatedly that FTL travel still takes time, and it's why multiple relay jumps are needed to travel the galaxy rather than pointing right at your target and blasting you off. Gotta avoid stars or hitting planets & proving why Sir Isaac Newton is the deadlieat son of a bitch in space.

[@jaydenliberty9536]

General Luigi Andromeda, No Man’s Sky, and a bunch of other games suffered from an unfortunate situation. The short version is that they are functional and even very, very good games today. But people don’t tend to even consider giving games that launch with problems like they had a second chance. (Or in other words, people make final judgements VERY QUICKLY after creating first impressions, and games that are good *now*, that don’t *launch* good, will always be hated as a buggy and broken game, even if every break has been patched and every bug has been squished since then)

[@adrienconverset6571]

Short version : technically meh for a AAA game. Story is meh too. Menus seem to be good for console but between meh and shitty for pc. Mechanics ... let's just say it has little to no replay value, even though it's technically a RPG (spells, inventory and weaponry-wise) Only two powers available at any time, no more class, and so on. Bosses are just big health sacks, no real outplay or "logic" behind them. The most annoying part imo is the triggers that spawn enemies for no reason. Story-wise it's weak. Mechanics-wise, it feels off about itself, kinda like BioShock Infinite. Technically it's ok but nothing amazing. So ... yeah.

[@RialuCaos]

Andromeda was alright. It had potential and could've been much better, but I believe it was managed poorly, which translated into a relatively subpar product. I do think all of the criticism of it is a bit overdone, and most people avoided playing it just because of that.

[@kevinwilliamenriquez2641]

This made me so happy. :)

[@tobys7026]

Nice video extra credits team!

"When did you become a Ezo Masa Effect physics expert?" "Last night"

[@archerbascha8757]

I noticed a certain lack of Tali in this video. I mean, she is a engineer who worked on the Ezo core. Also, Tali is best girl.

[@michaelalangordon6120]

Ash/Jack for me.

Cant wait for waiting for 5+ years for ME5! :D

[@morthasa]

6:44 - Awesome Innerspace reference! (Maybe. Even if not, it's really reminescent of that movie)

[@patrickstar1723]

Can we talk about how hyperspace weapons in Star Wars is terrifying or sci fi plagues like blackwing virus or the flood.

[@requiemlul3140]

Can we talk about your pfp? A true man of culture!

I appreciate your remixed Sonic level theme at the end.

This video is 50% lore 50% dating sim

[@laszlokaszas1003]

IDK if anyone will read this but here we go: I don't know anything about Mass Effect lore (shame on me) but I understand a little bit physics. I don't want to underestimate the writters but they were so close to be accurate that it bugs me. Using dark to gain "negative mass" isn't a bad idea (thought Im pretty sure the spaceship would break to atoms or even smaller) but using dark energy AND dark matter is a potencail way to travel FTL, and some scientist speculate that it can be done in our universe. First, you put the zero element in the top and bottom of the spaceship. In the front you generate dark matter, in the back you gererate dark energy. Second, the dark matter "pulls space-time in", so the planets "get closer". Dark energy "push space-time away" so the planets in the "farter away". Third, this this would create a "wave" in space-time and the spaceship basicly surfs in it. And lastly space-time can exptend FTL (like in the Big Bang) so if you create a big enough wave the ship can travel FTL. If someone is more educated and I wrote some BS comment. Grammar error due to English not being my first language.

[@SeanCrosser]

AFAIK a lot of this is basically countered by narrative in the games. Eezo is quite scarce (and I presume either volatile?), so you can't make entire things out of them. They're only ever used as mass effect field generators, and ship propulsion still relies on fuel drives. Dark energy is a handwavey explanation for why Eezo works, the tech doesn't actually manipulate dark energy or dark matter. And most importantly: all of the near-light speed travel options and most of the derivative technology is based upon being compatible with what amounts to pre-existing space railroads. The races don't make airplanes because they have railroads, so they make trains.

[@Fu3R4]

Mass effect is my favorite game series. Yes I even liked Andromeda but I am biased. Shame we never got a second. Extra points to you guys for not spoiling anything while exploring the mechanics of the universe!

[@SuperboyLilly]

ME5 is being made as we speak.

[@HeavensSeeker1]

1:43 That battery connection though lol

[@safe-keeper1042]

Extra Credits staff: no, we're not doing more Extra Sci-Fi. Now if we can get back on topic, what should our next episode be about? Disgruntled Extra Sci-Fi writer: er, um... oh, Mass Effect! And our angle will be how this sci-fi game portrays science! Extra Credits staff: ...wait a sec.

[@zmbates99]

Erin McDonald!! You go! I've got to remember to say awesome job next time I see her.

[@VersusMadrid]

Oh man! And so much more science to talk about that they got right! Like using Quantum Entanglement for instant galaxy spanning communication!

[@Sheamu5]

I'm so glad you only called it a trilogy and didn't mention Andromeda.

[@BTNMNKI]

I kinda love how lazily the Krogans are drawn 😄

8:09 [Faint cries of 'This City' in the background intensify]

[@TheGrimmGamer]

The Mass Effect trilogy was/is so damn good. I still mention it from time to time because it had that much of a positive impact on me.

[@The-rc9cm]

AAAHHH YES UPLOAD

[@charlieputzel7735]

I'd love to see you guys do an explanation of the warp drive in star trek, especially since some of the key principles were recently proven to be real.

[@Oh_Nanners]

You don't run a current through something by only connecting one side of a battery you silly goose ;)

[@Yao-fz6ie]

5:17 When the Calibrations are just right

[@mistertizio4094]

How do you define positive and negative current? Electric current is produced by the flow of electrons, it's nor positive or negative. Maybe you mean positively or negatively charged.

[@BlueDog241]

I came for a discussion about video games. I stayed for a lesson in science!

[@TheCreepypro]

man this game sounds dope well now that I have all this time I might as well play them

[@SuperboyLilly]

GAMES, it's a trilogy.

[@TheCreepypro]

@@SuperboyLilly sweet the more the better!

LONG LIVE TALI'ZORAH VAS NORMANDY NAR RAYYA!!! 😍❤😍❤😍❤😍❤😍

[@EmporerAaron]

I was just playing Mass Effect Andromeda when I saw this.

[@OmniSzron]

Didn't even mention the quantum entanglement communication. Still a great watch.

[@PureAwesamness]

Everyone who played the Mass Effect games heard EC hoping for Mass Relays and immediately broke out in a cold sweat because their existence would imply the existence of something a lot spookier. XD

[@sErgEantaEgis12]

Liara drawn in the Extra Credits art style is pure cute.

[@fullmetalkahn]

Dude, I just started Mass Effect for the first time this week! What are the odds?

[@OmusKnowsAll]

YES!

[@Plankensen]

WELL. It was the Reapers who made the mass relays, if i remember right.

[@booniebound7793]

More history videos please!

[@fiddleriddlediddlediddle]

I love that you chose raisins in raisin bread instead of the balloon analogy. Edit: Scratch that.

[@rodefshalom]

0:09 - Don’t spoil the whole ending!

[@LordAlchemist]

Indoctrination ending.

[@thetipoftheweek200]

Whoa, hang on. Protheans didn’t make the Mass Relays, the Reapers did...

[@sta697]

spoiler alert!!!
