I recently had this idea (which perhaps is not a new one, but I have never heard of it), that on the scale of the entire universe, time expands in all directions at once. I believe it can be proven or disproven with more knowledge, so I am posting it here.
If we look around us, we generally understand time as 'direction of changes' and everything we see moves in this same direction at the same 'pace'. An hour for me is an hour for you etc. Thanks to Mr Einstein we know this is not a precise description, but from what I understand, if we ceased all movement (relatively of course), time would 'flow' the same for all non-moving objects.
Now, I was thinking, maybe that is wrong. At least, on the scale of all universe. For some reason I can't attach any image, so if you are interested, look at this crudely drawn picture:

It is simplified, but the circle represents the universe as it is 'now'. It could be slightly better to imagine it as a 'bubble', but much harder to draw. Please have look and place our Sun and us at point 'A'.
The range between 'D' and 'J' is the observable universe - what's on the other side 'didn't happen' - 'isn't happening' for us. The strange thing is, though, that if we were a piece of matter at point C, we could see, and even be influenced by, points D and E which is 'invisible' for us.
This idea also fits nicely with the expansion of universe and even with the dark energy.
If it is right, then a galaxy 6 billion l. years away is not only 6 billion years younger. Time for this galaxy, relatively as we see it, would actually pass slower because of the distance. I am sure that all of you experts in cosmology will swiftly disprove me and my idea will degenerate into yet another fruitless mental exercise, but still, I thought it may be interesting. And I believe we have so little data about objects billions years away that proving how does the time pass there may be challenging.
Regards and have fun :) Sorry if my English wasn't perfect.
