Why space ships cannot travel the speed of light, or faster....
e=mc2 thus c2=e/m thus c=the square root of e/m. To make a ship go as fast as c, the energy required becomes infinite, as does the mass, because m=e/c2. It is impossible to achieve infinite energy. The length of the ship would shrink to 0. And finally there is time to consider....
If you take two identical twins, born at exactly the same time(don't ask me how) and put one on a spaceship that travels the speed of light and returns five years later... which twin is older? the one on earth, because when you travel at the speed of light, time stops.
So, my point is, William Shatner aka James T Kirk, should not have lost all that hair and gotten older. Time on the Enterprise stopped.
So does this mean we can never reach the far reaches of the universe? Well this waits to be seen. Some say, what if you could bend space even more than it already is. What if you could bend two pieces that are distant closer together? Then obviously you wouldn't have to travel as fast to reach it in the same amount of time! Kind of exciting... I think.
Maybe i should have posted this in an astrophysics thread? I hope all conversation doesn't come to an end now.. ;-)
