Now imagine you have a swimming pool inside a moving train -- what is the difference? <br />That is why they have swimming pools on moving cruise ships and it never happened that somebody would miss the swimming pool while jumping into it due to ship movement. <br /><br />BTW this is how Newtonian and Relativistic mechanics differ: the light behaves in some sense similarly to the man on the picture.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6234783319349274920.post-78752439959871641382020-06-10T18:12:35.703-04:002020-06-10T18:12:35.703-04:00Odd - While I write "g", right here and ...Odd - While I write "g", right here and right now, it looks just like #1.
