you know ive been thinking if matter/energy cannot be created nor destroyed?

Actually, as you travel towards the speed of light, time slows down and your mass actually increases. Because your mass has increased, the energy required to move you increases as well. What happens now is that by the time you get to light speed, in theory, your mass becomes infinite (no diet for this one :) ). Because your mass is infinite, the energy required to move you is infinite as well. As such, you cannot travel faster than light - can't have more energy than infinite eh :rasta:

We gonna talk about Star Trek next right?

For AppleD's sake, may as well mention I got a degree in maths/physics - yay me.:anon.sml:

Let me elaborate. If you travel half the speed of light you will have half the mass and age half as fast as a result. The closer you get to the speed of light the less and less mass you have. My question to you is, if when you reach the speed of light you have zero mass, what happens when you slow down?? does your mass come back or are all the molecules all scrambled around and such. Also if you went faster that the speed of light, although i think having a negative mass kind of destroys your existence, would have you traveling backwards in time. All relativley of course?? Woah! time to go smoke some sour diesle and really sit in this theory haha

Here's another one. If you build a spaceship that can go the speed of light, and you turn on the light inside the ship. Will the light reach the front of the ship? If so, wouldn't that make the light move at double the speed of light, and thus move backwards in time lighting up the front of the ship before you flipping the switch?

And would you flip the switch if the light were already on? If not, would the light stay on?

What if there is sub-dimension (or sub-space) that is readily accessible and has no physical limitations?

what if what if what if

Have you traveled at a speed of light?

It's only a theory.
Why would mass increase as you travel faster? This doesn't make sense to me at all.
 
The human mind is not capable of perception to the extent that would be necessary for us to understand the creation of matter.

You'd have to be going fast as hell. The universe is expanding at a rate which is impossible to get to. I'm not sure exactly how fast it's expanding, but if it's expanding at the speed of light, it'd be impossible to beat it, because going fast than the speed of light means going backwards in time :).

Actually, you'd be going forwards in time, and apparently scientists have broken the speed of light: http://www.cbc.ca/health/story/2000/07/20/speedlight000720.html
