the speed of light

if time stops at the speed of light then even if could go that fast! even 1 on the space ship could not move becase time has stops! i am wright or wrong love dr:)
 
The space shuttle Columbia didn't actually blow up.

It went back in time.

Mostly you're incoherent. Could you please form your words into a question?

Sounds like you're describing the time dilation effect when one travels closer to the speed of light, according to Einstein's Theory of Relativity (I forget which one ;) [The Special Theory - someone]). From an outside perspective, according to Einstein's theory, a clock travelling closer to the speed of light (or, in the General theory, a huge gravitational field [Thank you Wikipedia - someone else]) appears to tick over slower than a clock positioned from a stationary position looking at the moving clock. Whether they actually stop moving relative to your position I don't know.

I'm no physicist, but I can't really understand this sort of thing properly. Not unless I have a good sit down and think about it. [Or just look it up on Wikipedia - someone else again]
 
Time is relative. Saying that "time stops as you get to the speed of light" is like saying that the highway-makers on the side-of the road move faster as you press down on the gas more. Which isn't the case (since you are the one moving and not the markers.)

Time moves at different rates depending on how fast you are moving. In theory time moves slightly slower for someone on the highway driving at 70 miles an hour than for someone sitting on their couch at home. (Granting that it is an infinitesimal difference.)

So we get the "twin situation" common in discussions about travel at c. You have a set of twins. One twin stays at home on Earth while the other gets on a rocket-ship that travels at the speed of light.

If the twin planet-side could look into the rocket as it's moving away from the Earth he'd see events slow down inside the rocket as it speeds up until it reaches near c at which point everything in the rocket appears to stop.

The twin on the rocket, if they could look at events on Earth, would see the opposite effect. He'd see things speed up faster and faster on the planet as the rocket's speed increases when he reaches near c things appear to be moving very, very fast on the planet even though for him time is moving normally.

At 100% of c this gets... odd. In fact it's technically -on this front- not possible to be at c because at that speed time doesn't seem to exists -you enter a sort-of divide-by-zero situation ;).

"In theory" someone traveling at a significant rate of c could travel into the future, but technically never leave the present.

They don't, just as nothing can actually reach the speed of light in a vacuum. It's an asymptotic relation: the hyperboles can never touch its asymptote, even if it can get closer and closer. The same way, the relative time of a moving object with respect to another can never actually stop, even if it can get slower and slower.

The spaceship can't reach c. Time can't stop. Not in this universe, at least.
