Well basically, it's impossible for any object with a mass to travel at the speed of light; however, it is possible for any wave (such as light, obviously) that has no intrinsic mass to travel at the speed of light.
Theoretically and mathematically, science shows that the amount of energy required to accelerate an object to the speed of light tends towards infinity and therefore it would be impossible to take an object that is slower than the speed of light and accelerate it up to or past the speed of light.
Yes. The energy which an object has due to its motion will add to its mass; therefore, the apparent mass isn't actually constant as the body is accelerating =P Haha. In other words, the faster it is already moving, the more difficult it is to increase its speed. Because of the equivalence of mass and energy, by the time a body reaches the speed of light it would have an infinite mass, meaning it would have taken an infinite amount of energy to get it there. This is according to Newton's 2nd Law, where:
F = d(mv)/dt
Possibly it'll never happen if the scientists have got the forumula right.
True... but by definition, no theory can ever be known to be 100% correct until every contradictory theory is proven wrong =P
That brings me to the next point, if we cannot travel the speed of light, the human race is doomed earth cannot substain this population indefinate. Unless scientist comes up with a formula to create artificial wormholes to take us to other areas of the universe, so the human race can populate & carry on.
Haha not really. It would still take many generations to get to another planet somewhat similar to Earth, even if we traveled at the speed of light. Humans cannot physically (nor mentally, for that matter) tolerate being in outer space for that length of time.

Well, I'd say that's not a scientific problem, but a social or social psychology problem, along with a mix of politics (the Chinese try to limit family sizes) and other disciplines. I'd say don't lose any sleep over population growth either. Cultures and nations seem to have, perhaps, a built-in thermostat to a certain extent. For example, if it were not for immigration here, I think the stats show that we, and all Western European nations, would have a declining population. Our problem would be population shrinkage. If that happens within individual nations due to social, psychological and culteral factors, I reckon it'll happen globally in time. I've never been too worried about population expansion, believing that in time it'll self-regulate. I don't believe the corny science-fiction idea that "to survive we have to escape from the Earth". 🙂
How about staying on Earth, not fleeing from mistakes past, and learning to master ourselves and our lives on this planet?

If you were traveling in a car at the speed of light, and you turned on your headlights, would they do anything?
Ah, that old chesnut.
Answer, yes, because of the theory of Relativity. If you were in the car you would see the lights as you would expect, however an observer at a point where the car is travelling at the speed of light away from the observer will not see the light as it cannot relatively travel back to the observer.

You also then have to bear in mind that science tells us, the faster we travel the slower time goes. So if you consider that an object is travelling at a certain speed (which is measured in meters per second) and then consider that this causes time to slow for that object, it has actually travelled the same distance in less than a second, which means that it has a faster speed than you initially observed. If the speed is faster then the time is even slower which makes the speed even faster and thus the time slower again and so on and so on. This is something that was defined by Lorenz and other scientists and is along the lines of the Lorenz Contraction.
Hiye Energylz, was I allowed to pick up that paragraph and underline a fine thought? And then, will you read one more of mine, this time simply copied and posted?
'kay, back to the beginning, or forget about history (a bird talks like that!), open a new page, wo'ewwuh: In effect no problem, have sussed this out: accelerating eversofaster towards speech-'f-lite time is going t' slow down, presently space is shrinking! These findings were being discovered on one of those days and wekings says it's ow-Kay. Fact is, a light particle is all over the PaLACE in no time, the photon that is. Time dilatation has been described more than enough, though the identical approach to space got me a while to stumble upon once again.
This our world is fantasy with sheer insane possibilities, know this now. Put all fine ideas ever been conjured up, they are relatively nothing compared to that. Nature is even waiting for some daring, loving, freaky fans. .. when somnambulistic dreams encounter feasible wishes, easy.
ps- maybe on the brink of C (lite-velocity) the vacuum-energy, a quantum-jump or summing wreally weird is going to ..dunniouw.
