As space expands the gravitational potential Energy increases. So does the potential energy between Atoms and quarks and so on. I have read several times that these effects are so minuscule that they are negligible. However, it does not seem so to me when considering the large timeframes of the universe. The Hubble constant is about 2.2x10^-18 s^1. 13 billion years are 4x10^17 s . Ignoring the fact that the expansion is not constant over time (though slower in the past nonetheless accelerating) when talking about the origin and future of the universe these numbers are too much in the same ballpark as to being ignored. What am I missing? Thanks in advance
This is too basic of a thought to speculate about its implications on my behalf. But an increase in pot energy and hence increase in mass is somehow desirable concerning dark matter.
