I'm not a scientist, but there is some school of thought that the universe is expanding (or did)quicker than the speed of light. If you subscribe to the Big Bang theory, the universe was a spec and one millisecond later, it was well, pretty big. And it continues to grow . . .wah, wah, wah

Ah yes, the "Big Bang" theory. what a load of crap. One guy in a wheelchair who loves to be an idiot (evolution? we evolved from monkeys and fish? Then why are there still monkeys and fish? What an idiot). Yes, the universe is expanding, but if I tell you why I'll be jumped by the surprising number of atheist in this website.

Oh lord...

Here's something for you to consider. We know that the universe is expanding. We know the rate at which it's expanding. If 5 minutes from now the universe will be larger, then the inverse must also be true and thus 5 minutes ago the universe must've been smaller. Since we can measure the rate of expansion, we can predict where it'll be tomorrow and also determine where it was yesterday. Using the awesome power of math, we can trace the rate of expansion back about ~13 billion years to where logic says that it must've originated from a single point in space-time.

But you're right; a magical bearded man in the sky "magiking" the universe into existence in 6 days is far more plausible.

And Jebus dude, at least make an effort to understand evolution before you try to mock people who've spent their entire lives studying and developing it. You sound like one of those people who stand outside schools and libraries with signs that read, "My gram'ma weren't no monkey!" Let me ask you a question: If evolution doesn't exist, why then are there over 150 different breeds of dog in the world and not just 1?

just out of curiosity and a theory of my own, but what if our universe started small but over the millions of years its expanding? we hear everyday on how its expanding the vastness of space...

Bad wording. Singularity is the word given to describe infinite density, zero volume. True, general relativity itself predicts the infinite denstity of black holes, but then breaks down once that infinite density is reached. As far as we know, when infinite density, or singularity,  is reached, space-time no longer exists. The only thing we can do with singularities is speculate.

Yup, you're correct. My apologies. Apparently, the singularity has infinite time-space curvature that breaks down from relativity, but apparently that's expected because now it's quantum.

Black holes seriously confuse the heck out of me.

Isn't FTL travel possible in the ME universe because Mass effect fields allow for mass to decrease to ridiculously low levels?
FTL travel is theoretically impossible according to Einstein's equations, but who knows what we'll discover when (if) the unified field/superstrings theory is resolved.
Anyways, travel through wormholes through space (and maybe time) is theoretically possible, it would require some "exotic matter" to stabilize the wormhole though, but it's still not FTl travel.

Yea my point about black holes and singularities is that they are unknowable. Since man can not observe or experiment on a black hole, and all current mathematical modeling breaks down upon singularity, we only have speculation left.

Edit: We are trying to figure out black hole type problems with the Hadron Collider.

The majority of  physicists, astronomers and whoever else in the scientific community accept the universe expanding as a fact. Not many people are debating it. There are however debates on whether or not it will expand for eternity.

Making a metal object is impossible.
Leaving the atmosphere is impossible.
Reproducing tissues artificially is impossible.
etc,

The point is, a lot of things are considered to be impossible before they are proven possible.
We know so little about the world and it's own rules that we can only guess.

[ScepticMatt]

not completely true with general relativity. You cannot travel ftl compared to your local spacetime, but that doesn't mean that the spacetime around you couldn't be bent so much that you travel ftl compared to an outside observer. So even if you use a Alcubierre drive ("real world" warp drive) or wormholes, you aren't ftl locally.

#Edit: Quote from Wikipedia:

On the other hand, what some physicists refer to as "apparent" or "effective" FTL[1][2][3][4] is the hypothesis that unusually distorted regions of spacetime might permit matter to reach distant locations faster than it would take light in the normal or undistorted spacetime. Although, according to current theories, matter is still required to travel subluminally with respect to the locally distorted spacetime region, apparent FTL is not excluded by general relativity. Examples of apparent FTL proposals are the Alcubierre drive and the traversable wormhole, although the physical plausibility of these solutions is uncertain.

Okay, let's start with the fact that Einstein's relativity prohibits anything with mass to travel at or faster than c. Mass Effect gets around this problem by claiming that "eezo" can alter the mass of objects when subjected to electric charge. Positive charge increases mass allowing artificial gravity, while negative charge decreases mass allowing FTL. Now, obviously, no such substance like element zero exists in our universe. We would've discovered it by now in particle accelerators. Furthermore, the entire dark energy phenomena is ludicrous in the context of the game. Dark energy is simply a phrase used by physicists and astronomers to describe the "missing" mass that must exist in the universe. Baryonic matter, or light matter that we can see, makes up less than 5% of the energy/matter in the universe. We know this from the effects of gravity on the motions of galaxies.

As far as relativity is concerned, the best way to think about the speed of light is this: light moves at c for a very specific reason- it cannot move at any other speed. In fact, you and I and everything that exists also moves at this same speed. The difference is, photons are massless and never move through the dimension of time (the fourth dimension), whereas particles with mass move through both time and space. That is why as your velocity increases time slows down! And that has been experimentally verified beyond any reasonable doubt. GPS is the perfect ongoing experiment for relativity. So, Mass Effect never says Einstein is wrong, it just skirts around the issue with an unlikely solution. Technically speaking, wormholes (mass relays) are not prohibited in physics, but they're most likely impossible to create and hold open.

The point is, if Bioware decided to use our world as their universe, Mass Effect would be boring. We'd be stuck in our solar system. Or at the very least, to nearby stars. Suspend disbelief... the game is too fun not to!

° K is the absolute zero. Neutrinos seems to travel a tiny bit faster than the speed of light though.

UKStory135 wrote...

The reason that you can't travel the
speed of light is because as an object with mass accelerates toward the
speed of light, their mass approaches infinity. Thus, it would take an
infinite amount of energy to move just one atom at the speed of light.

There is also the problem of acceleration. "Instant acceleration" would be fatal, and how much acceleration can you be subject to anyway? For how long? Because it's not just the intensity, but the time you are subject to it. I tried something some time ago, and according to the FTL speed from the codex, if I took a decent value of different Gs (without knowing if someone could die from it after all the time) and every time they ship would've reached the 12 l-y thing looong before attaining FTL speed.

There's different kinds of science fictions. Those bending on the f(antasy)iction side of things, and the one bending on the science side. Mass Effect is kinda in-between, it tries to explain things, but by coming up with everything rather than trying to use theories in a couple of places and known physics laws.

[I...AM...KROGAN]

Space is expanding and evolution is happening. Both are observed facts. Scientific theory attempts to explain why they are occurring; what mechanisms are involved. That is where Big Bang cosmology and Darwinian Evolution come into play... not that they have anything to do with one another. One is physics, one is biology. I don't, however, think this is the place to discuss such topics. This thread is about whether ME should use FTL as canon.

[JKoopman]

Technically speaking, the mass effect would account for a spacecraft being capable of traveling AT the speed of light. But reducing a ship's mass--even to zero--wouldn't allow it to travel FASTER than light. You'd need some kind of wormhole for that to occur, and that's not really FTL so much as it is teleportation.

Completely hypothetical particle. It's in the same book as wormholes, string theory, alternate universes, and unicorns.

Did you just compare Wormholes and String Theory to alternate universes and unicorns? Now you're just harshin' on my science.
Side note: stop acting like science and religion are mutually exclusive. They're not, and you are moron if you think they are. This isn't a science v. relgion thread anyway. Can we just get back to telling the OP that he's an idiot please?

Hmm wormholes.  Mathematically possible/allowed in general relativity thanks to (possibly) the wonderful casimir effect .  They are in effect the only way to travel faster than the speed of light (but require negative energy densities to exist).  

Not to be rude, but hasn't a debate on the scientific accuracy of ME already been repeatedly discussed?

Im sorry, but your wrong. Your kind are the ones who ignore the truth like the way most homosexuals are atheist (what a coincidence......). And yes, there is an all powerful being in a third dimension controlling everything. When you die, you'll be in front of him, he'll tell you that you were wrong all your life and then toss your sorry ass to hell (BBQ!).

But seriously, "people whu study this"? No, those are people looking for excuses to be atheist and support they're own made up beliefs like so many before them. Why are there 150 breeds of dog? They always existed and 30% of them were breeded by us Humans to make new breeds (Rottweiler I think is one of those cases). Evolution those not exist. Many people say that those who live in cold ares grow thicker hair; that's bull, there is no such thing as that. Go to Antarctica and see for yourself. But of course, this won't change your mind, so just waint and you'll see Im right, hope you remember me when the hour is upon you.

But yes, the wormhole theory seems like the sure way to do it for now, we'll have to wait until we can actually control negative energy, which seems deadlier then radiation in my eyes.
