If I suddenly got faster than light, I would try to slow down! :V

[Darvi]

Oh, I know.

Play it!

[MaximumZero]

Oh, I know.

Play it!

I got nailed for someone already having made that joke on the second page, man.

[Darvi]

So?

[Sergius]

If you loot a chest in the past, it'll be empty in the future.

But if you loot it first in the future, it'll have even better stuff in the past!

Yeah man, gotta watch for those space cops, they got their radars everywhere.

[Roboboy33]

If I got my hand on FTL and had a ship with it, I would conduct research on photons, because if your moving at the speed of light there will be photons travelling beside you at the same speed as if it wasnt moving at all.

[TheBronzePickle]

I'm probably one of the few people who would try to apply the FTL principles to a computer system. Even if the only application would be to make data move faster, I'd imagine that would still give a decent boost to computer speeds. Alternately, you could have a hyper-fast coolant flow that could handle massively overclocked CPUs.

being able to use FTL computers might depend on the kind of FTL
if it is a warp kind of FTL, there might be problems of interaction between FTL signals, and also between those signals and the case.

what happens when you warp space on an object?

what happens when you warp space on an object?

Depending on which part of the warp drive's hitting it, it'll either be ripped apart or crushed together. Either way, obliteration. We're adding and removing empty space, here.

[mainiac]

Edit: Ok, let me clarify. FTL exists. You don't have your hands on it yet. What do you do?

Cease to exist.

FTL defies causality because any FTL device doubles as a time machine.  Now we don't know what the effects of a macro-scale defiance of causality would be but it seems to me that either the physics or abuse by some time traveler somewhere down the line means that pretty soon we'd all get erased from time, back to the future style.

[andrea]

not all FTL breaks causality.
alcubierre drives ( warp drives) don't, for example.
probably due to the fact that you aren't actually moving or accelerating the ship, but just riding a bubble of still space that moves... which somehow doesn't break many equations. ( it also requires a lot of some kind of matter that might not even exist, but that is beside the point)

the important thing is that you are subluminal in your local space.
I think.
this is what I understood from wikipedia anyway

In Star Trek: The Next Generation, computers are supposed to run inside some sort of... mini warp field, at FTL speeds, whatever that means.

[TheBronzePickle]

I don't see how breaking causality by going faster than light would be the same as time travel, anyway.

Time is the fastest thing in the universe, but it doesn't really travel at infinite speed. If you travel at superluminal speed, yes, you can outpace the light output from the supernova and probably tell someone far, far away, 'hey, look over here at such and such time and you'll see this awesome supernova' but if you turn around and go back, even superluminally, you won't suddenly pop up at the supernova before it happened.

[Eagle_eye]

You may not be able to, but you can communicate information to people before the event happens in their reference frame.
