Expanding time?

I believe you have to get rid of certain assumptions if you want to get the "whole" picture of how everything fits together in the universe from the smallest constituent parts to the largest(that's what most physicists say anyway).I know this might cause more confusion than understanding but unless we drop certain kinds of realism and locality, all the effects seen in experiments in different fields of physics cannot be explained. Take the photon for example. Andromeda is now 2.4 mln. light years away but in the past, theory says, it was closer. Regardless of this, a photon emitted from a star within the galaxy, will not travel any distance towards the Milky Way, from its frame of reference. This is because at c, time dilation becomes infinity so any distance within the universe from the photon's frame of reference is zero, whether there is metric expansion or not. What's even more mind-boggling is that every emitted photon is everywhere in the universe at once, while in transit. The enigma lies in the question - what is "everywhere" for the photon? And what is the "universe"?You cannot grasp this while holding onto to realism and locality. Those 2 notions are characteristic of our experience, not of how the universe is. Space and time are relative concepts, not fixed ones. They utterly depend on the observer's frame of reference.

Length, time, colour and even mass depend on the observer's frame of reference. When you know how relative these concepts are, i am sure you'll be able to make sense of most of what he was saying in the post below: See also here:Special Relativity Simulator - About No, you won't. That's one of the postulates of the theory you are describing. Nothing can travel FTL and no material object with mass can travel at the speed of light. One day, if we could utilise energy in quantities like that of the Sun, maybe we could get near the speed of light. But that's pure speculation. They don't believe, they are certain. Yes, but time is relative. It may seem like time passed at its conventional rate for you, but your grand-children might have already died of old age. Right, time is relative. c? Distance, straight line, time, colour, mass. Edited by Agobot, : No reason given.
