Here:
We are accelerating in our expansion.
If this is the case, the universe 50 trillion years ago, would be much, much, much tinier than compared to today, yet it would still contain all the same amount of energy and mass.
50 trillion years from now, if this acceleration is a constant rate of accleration, our entire universe will appear to have the same exact properties as teh universe 50 trillion years ago appears to us today.
I wonder what the intelligent consciousnesses that inhabited that super tiny (in our perception) universe that existed 50 trillion years ago, thought about the universe that existed 50 trillion years before them.
If time is also accelerating, this makes the passage of time, (in our perception), of the universe 50 trillion years ago, go very, very, very slow indeed. Every electron disappearing and re-appearing at a much, much slower rate. Perhaps all that compressed energy was actually disappated by the slower movement of time, as amount of energy, and time are inextricably linked.
