AI Thread Summary
The discussion explores the potential fate of the universe, particularly regarding black holes and their role in consuming ordinary matter. It raises the question of whether all matter will eventually end up in black holes, with references to Sean M. Carroll's views on the topic. Participants debate the nature of dark matter and dark energy, suggesting they may not be actual forms of matter but placeholders for unknown phenomena. The conversation also touches on the long timescales involved in cosmic evolution and the implications of black holes on galactic structures. Ultimately, the fate of the universe remains uncertain, with various theories and speculations presented.

Yes I think I mentioned something about that with the Feynman diagrams.

I *think* Chronos is referring specifically to a physical mechanism rather than a mathematical model.

Mathematical models are not guaranteed to be inherently true for physical mechanisms, if you take relativity and input speed values that exceed c and end up with a negative value for time this is not really indicative of physical reality.

Ergo chunk that model and come up with something realistic which actually explains physical reality. If you're going to misuse or abuse the mathematical model it won't be very useful.

Yes I agree you should stop doing this. The onus of the burden of proof is on you here - I am not refuting the standard model, nor I am trying to promote that anything can travel back in time without any proof which you seem intent on doing.

So as both me and Chronos have now requested - apart from diagrams/mathematical abstractions - give us a physical mechanism for time reserval? My guess is you cannot and that is why you are skirting around the issue, now if youre in a little over your head then fine, but don't keep pushing this idea forward.

Sorry I didn't mean to be pushy. The physical mechanism is described well by Feynman but I don't want to push the issue so I'll let you investigate that if it bothers you.
