This can work hypothetically, but you need a supra-conductor, a light-bulb that doesn't get hot and a perfect solar panel.
[QUOTE=Ali Legend;28196945]I've never got my head around this concept to be quite frank. Your eye 'works' because of light, right?

The funny thing about light is that even if you're travelling at the speed of light, light will still hit you at the speed of light, whether looking forwards or back.
You cannot go faster then the seed of light fool

[QUOTE=Rad McCool;28205692]You can't literally travel faster, or as fast as light. But you can create the same effect (getting from A to B):
[B]a)[/B] You can stretch space, the "space-fabric", in a way that you wouldn't have to move at all. You rather manipulate the space to "get to you".
[B]b)[/B] You can rip space, opening a wormhole.
(Wormholes and black holes might very well also be used for backwards time traveling)
Both are physically possible, but they require enourmous amounts of energy and the practical problems are over-whelming.
[B]Bonus)[/B] Simply travel close to c and time dilation will make your trip to the stars pass in seconds. Though the stars in question might have very well blown up by the time you get there (again, time dilation), that's why options a) and b) are preferable.[/QUOTE]
You hit the nail on the head

True dat
I thought when you go faster than light your perception of time is normal, say a second passes but to everyone else you and other people travelling at the same speed would have been gone for years.

Nice one.
Anyway, there is no reason why you can't go faster than the speed of light. Other than that you can't accelerate without hitting something. Remember Newton's laws. One of them is: An object will not loose it's monumentum without another force influencing it. Now what happens if you push a rock for several years? At some point it has to go as fast as the speed of light. If it will go faster? No Idea, because it's energy tends to be really high.

It still wouldn't work moron, you'd be getting the same amount of energy that you put into it.

Man you dumb. Speed /=/ acceleration

To travel faster than light (and survive), you would have to exist in a section of space that is not traveling faster than light. That's why a lot of fictional FTL travel uses 'warp' or 'hyperspace' or 'subspace' bubbles.

Time dilates and slows as you approach the speed of light, but no one has any idea what would happen if you actually exceeded it. Basically, if you have a positive mass (and as no such thing as negative mass, that means everything we know of), you cannot exceed the speed of light, because the energy required is infinite.
You can 'effectively' make things travel faster than light, but these virtual particles and you can't send information anyhow (via the Hartman effect).
The only other thing that we know of, that moves at FTL speeds (or least we're pretty sure it is), is the objects outside the Hubble Sphere, which move away from Earth at a velocity faster than the speed of light, but that it is due to the expansion of space.
for fucks sake man we're not even at TL1 yet
[QUOTE=Clever_Balls;28207012]Man you dumb. Speed /=/ acceleration[/QUOTE]
Ugh, what is the problem?
Maybe when Half-life 3 comes out we'll be able to travel faster then the speed of light.
Isn't light speed just to fast to measure or something?
[QUOTE=commander204;28206671]Nice one.

There is reason. The energy required would have to be [I]more[/I] than [I]infinite[/I].

Basically, (even though relativistic mass, and Newtonian mass are different, it's good enough to get the point across), as the energy of an object increases, it becomes more difficult (requires more energy) to increase its velocity.
To reach the speed of light, an object must have an infinite amount of energy, just the same as the relationship between energy input of a car traveling 100 metres per second, and 0.50c would not be linear.
But what about light? If something requires an infinite amount of energy to move at the speed of light, how can photons travel at that speed?
They can travel at the speed of light, because photons have no (rest) mass, which is why the speed of light is deemed as the absolute maximum speed a non-negative mass particle can travel.
Ok thanks, for clearing that up.
That said, if we find/create particles of negative mass, fuck yes, galaxy here we come!
Just hope the reapers aren't out there waiting.
One should perhaps also mention Tachyons. They are particles which travel faster than light. And the more energy you give them, the [I]slower[/I] they go. And lightspeed is their slowest possible state. Tachyons are believed to exist in 3-time dimensions and 1-space dimension (sort of inverted from our common world). But they have never been found or proven so their existance is much debatable.

It's okay, our universe is actually ridiculously whacky, and 90% of quantum mechanics would be dismissed as crazy if it wasn't validated both mathematically and experimentally.
For example, everything exhibits qualities of being both a wave and a particle at the same time, superposition and so on.
Here's a link explaining a bunch of interesting effects.

The problem is that if special relatively holds true, then true FTL travel is impossible, including tachyons, because the particles would be traveling back in time, violating causality.
So even if tachyons did exist, we would not be able to interact with them, and vice versa.
Of course, that doesn't make FTL travel impossibl, by means of contracting/taking shortcuts in space.
Interesting.
[QUOTE=Hazard Fox;28197737]You could essentially just go 1,000 LY away then come back and skip all the advancements we've made right?
Say you leave in the PS2 era, you'd come back in a Neuro-net or something like that era and the moon would be colonized....it would be like time travel right?
Or is this totally incorrect?[/QUOTE]
Light =/= Time
[QUOTE=Murkat;28207811]Light =/= Time[/QUOTE]
He's right though, you can time travel forward, just go in circles at 0.99c, and barely any time will pass on your end, whereas time will pass normally from Earth's frame of reference.
what if we made a rocket and put it very very far away from earth and point it to Berlin, then launch it at multiple times of lightspeed that it hits Berlin at exactly 30 january 1939
that way ww2 might've ended very quickly
If we do get light speed we need light speed donuts.
hmm interesting concept, but we would have to go a long way, and have extremely powerful telescopes to see back 65 million years.
My god this is genius.

[QUOTE=geoface;28208001]hmm interesting concept, but we would have to go a long way, and have extremely powerful telescopes to see back 65 million years.[/QUOTE]
And it wouldn't be 65 million years, because space has been expanding the whole time.
Simple answer, no.
Long answer, no.
It just sucks that we can't even see humans from the geostationary orbit which is only 36 000 km away. At least with normal light-cameras, because we hit the visible light wavelength before that.
[QUOTE=LuaChobo;28208341]God damn these threads, they are epic but always remind me of people saying they have "super sonic hearing" so they hear at the speed or faster than the speed of sound, so they can hear, or hear things before the sound is emitted causing several paradoxes for the latter.
Or I'm just retarded and tired[/QUOTE]
You can hear things faster than the speed of sound, you just have to convert the sound into another form of energy that travels faster, and then back.
Waiting for aVon to come and actually say something intelligent and actually correct.
[QUOTE=Zeke129;28197017]If we went faster than light wouldn't time around us pass by infinitely fast and we'd instantly die as the universe would end[/QUOTE]
I hope not.
