Last I heard, FTL travel was about spacetime shortcuts, not FTL velocities.

In ME, we have two means of getting around: 1) using the ship's FTL drive, to drive around planetary systems and star clusters, and 2) using the mass relays, for long-distance travel. Why would they call the ship's FTL drive "FTL" if it didn't move the ship faster-than-light?

Because it is a mean of FTL travel? You may have heard of the Alcubierre drive, imagine something similar. http://en.wikipedia....lcubierre_drive

From ME Wiki (that site reliable? they say it's all from codex):

"FTL, an abbreviation of faster-than-light, is a method of traveling faster than the speed of light which does not involve the use of mass relays."

Not much room for ambiguity there.

Why? It still says traveling.

Mass Relays just do a better job than FTL drives, that's all.

Element Zero is the big part.

Something with Zero mass is no longer bound by the speed of light, which is pretty much what the space travel in the ME universe is all about.

Could it possible? Of course. You'd have to be insane to think we've discovered everything there is to know about the physical universe. We hardly know a thing about quantum mechanics.

I think maybe they're being a little loose on some things here.  Technically, an object with no rest mass will have a max speed of lightspeed, c.  Assuming you don't do other things such as folding space, for example.  I think that the relays do that.

Element Zero would be classified as what, today, is called exotic matter.  Most present day theories for FTL travel rely on the use of exotic matter.

Actually there is no way to show that moving at the speed of light is the fastest speed ever attainable without the use of folding space and wormholes.  Theoretically the universe expands at faster than the speed of light and therefore something in the universe moves faster than the speed of light without the use of sub-space travel.  Therefore, this shows, to some extent, that speed is purely relative and that faster than light speed travel is attainable.

It says traveling faster than the speed of light, which was my whole point before I forgot what this argument was about. So if you're one of those guys who must have the final word, I'll just let you have it.

Doesn't QM say that some particles can reach FTL velocities?

What about: Tachyons? etc.

But anyway, the intro text seems to imply that "mass effect" alters spacetime.

Tachyons are a purely mathematical concept. And for a particle to reach FTL velocities, it would have to have some sort of "infinite mass"; as mass breaks down with increased speed and the only way to overcome that would be to have an infinite supply of mass, which, of course, is impossible according to our current understanding. It's also the reason we will never be able to create a wormhole.

Isn't it the other way around? The faster you go the heavier you get, so only things with no mass to start with could reach 3000000m/s

E = mc^2, and E = 1/2mv^2. Mass tends towards infinity as speed increases, reason why its pretty much impossible to reach the speed of light as mass increases the amount of energy needed increases with it, so theorectically the amount of energy needed to get at the speed of light is infinity. Even if you did reach the speed of light or close to it you're still going to run into time dialation. Time slows down closer to the speed of light and distances contract. 30 secs for the person going at the speed of light is like a few hundred years for the person on earth. They recently proved that large masses warp space-time. Interesting stuff Special Relativity and General Relativity.
