Woohoo for classical physics then! But are you telling me then, Coelho, that if I push the end of the bar the other end won't move for something like a million years? And if so, how can you have the first (lets say) 100 lightyears of bar bent, and the rest of it still strait because the waves haven't reached it yet? Wouldn't this have to result in the iron bar bending a good deal at the mere push of my finger, or breaking altogether?
Gandalf_The_Grey Reviewed by Gandalf_The_Grey on . I need somebody knowledgeable in physics So I have a little quandary that's been on my mind (on and off) for a good while now, hoping somebody can explain this. Now as we all know, the speed of light is currently considered the "universal speed limit", the fastest matter or energy can travel. So we'll keep that in mind. So, imagine that I have an iron bar (we'll just take away gravity for convenience) that's so long, it stretches from one end of the galaxy to the other. By this I mean the longest end to the other longest end, Rating: 5
