TL;DR Summary
Since the universe exploded (big bang) the velocity of objects in it changed, could the same be true for our arrow in time (relativity aside).
Is it theoretically possible that the whole universe is decelerating in time?

My question originates from the discovery, that objects further away accelerates away faster.
Is that acceleration measured from us or from the center of the big bang?

Please define what you mean by this.

Is that so? What's our velocity now then, and what was it earlier?

The arrow of time is a binary thing. This way is the future, the other way being the past. There's no magnitude to it.

Is it theoretically possible that the whole universe is decelerating in time?
You seem to be referring to the rate at which time flows, in which case I'd again ask you what rate it runs now, and what rate it ran earlier? It makes no more sense than saying a meter is a different size at this end of the field than at the other end.

They don't. The rate of expansion is not a speed or velocity. Different units (1/sec), vs m/sec.

It did not explode.

There is no such thing. You have quite a lot of misconceptions to clear up :smile: Please use our "search" option to find some topics about Big Bang, where most of this misconceptions were discussed.

Thank you for the quick answers. It is quite tricky to understand these concepts, not alone knowing some parts were explained to me incorrectly. I will look into the forums.
 
I asked a question here, probably over 15 years ago on entanglement and I appreciated the thoughtful answers I received back then. The intervening years haven't made me any more knowledgeable in physics, so forgive my naïveté ! If a have a piece of paper in an area of high gravity, lets say near a black hole, and I draw a triangle on this paper and 'measure' the angles of the triangle, will they add to 180 degrees? How about if I'm looking at this paper outside of the (reasonable)...
Thread 'Relativity of simultaneity in actuality'
I’m attaching two figures from the book, Basic concepts in relativity and QT, by Resnick and Halliday. They are describing the relativity of simultaneity from a theoretical pov, which I understand. Basically, the lightning strikes at AA’ and BB’ can be deemed simultaneous either in frame S, in which case they will not be simultaneous in frame S’, and vice versa. Only in one of the frames are the two events simultaneous, but not in both, and this claim of simultaneity can be done by either of...
