There is no infinite energy baseball bat I think we can all agree on that. But this particular question is answered now I feel, and I can move on to understanding how it's possible that light travels at the speed of light regardless of the observers' relative speed to each other and light.

Yes, I have understood the classical mechanics, but was wondering about this particular fact. Using an infinite energy baseball bat, and striking a ball with it, would keep the ball moving forever at light speed in a vacuum, so to speak.

Alright, so theoretically anything with mass could travel at almost the speed of light forever without any thrust applied to it after it had reached a certain speed. This has bothered me for a while, and I wasn't sure if something other than Newtonian physics was going on at this speed, when it...

Hello everyone! Let's say that you were to attempt to go as fast as possible on a spaceship with the mass of an average car in an absolute perfect vacuum. What I am wondering is, that if you were to reach a certain speed, and stop applying energy to this imagined spaceship, would the spaceship...
