Thank you very much for all the answers

OK I have just got a few questions. They have probably been asked before, but I have looked and can't find the answers... Question 1: I understand that if something is completely stationary, then it moves through the time dimension at the speed of light..? So if I was sitting stationary, at the centre of the universe (assuming that the universe is all that there is, and its not itself moving in some other body), then all I am traveling through time as fast as is possible? Now my question is, when I stand still on earth, I am no longer stationary relative to the universe (because of the earths movement/rotation). So what percentage of my speed of light "allocation" is used up in movement when I am stood still on earth...? A pretty pointless question I guess, but I have always wondered... Question 2: Imagine a train is traveling is traveling at exactly 500,000,000 MPH (the number isn't important, just very fast) in a perfect straight line. Imagine on that train, there is a person with a torch. Now imagine there is someone standing on a platform watching this train. Because the train is traveling so fast, everything in the train would appear to be happening in slow motion as he observes it from his stationary perspective (as the man waves to him, he would see the wave in slow motion)...? So, from the stationary mans perspective, when the torch is turned on, would he see light traveling in slow motion too? Would he see the light traveling away from the torch slower than if he were to turn on a torch himself, stood on the platform? Question 3: This might be a stupid, pointless question, but it has always puzzled me. I am under the assumption that nothing can travel faster than the speed of light. Light travels 299,792,458 meters in a second. So imagine that I have an infinitely strong steel bar that is 300,000,000 meters long. It cant bend or warp. It cant be compressed in any way. Now, if I push one end of the bar, the other end will move instantaneously 300,000,000 meters away at the other end? If that is the case, has a force just been transmitted faster than the speed of light...? Thanks for taking the time to read my questions I look forward to hearing the answers Thanks everyone
