Does time stop at the speed of light?

[Wombat]

If you traveled into space for three months and then came back to earth everyone that you knew would be dead. Time does change as speed increases. It doesn't require that you travel the speed of light to get it. Even at 50,000 MPH there will be a slight change in time. This has been tested with 2 atomic clocks and a rocket. They set one in the rocket and sent it up and left one on the ground. The one in the rocket was about 2 seconds slower.

Besides all that traveling at the speed of light is impossible. F=MA would be the reason why. Once you hit the speed of light your mass becomes infinite so you would then be required to have infinite thrust to go that speed which is impossible.

A Newtonian way of thinking is all that makes sense to me. I give up. If you all won't read all of the thread, and quit posting the same thing over and over, and not answer my questions, then I just give up. I would love to debate over physics with you all, but not when it's just some people posting stuff and ignoring my posts.

Nothing wronge with you all's idea of the defintion of time, just is illogical in Newton's Laws of Physics.
