the transition of the universe from the degenerate era to the black hole era and finally to the dark era depends upon whether or not proton decay occurs. If it occurs, it will be relatively soon, if it doesn't occur, it will be much much longer.

"All predictions of the future of the Earth, the Solar System and the Universe must account for the second law of thermodynamics, which states that entropy, or a loss of the energy available to do work, must increase over time.[1]" True for time moving in the forward direction. It seems the opposite would hold for time moving backwards. The universe, being symmetrical, has to do both simultaneously. There is not an arrow of time, there are arrows of time, pointing inwards or outwards depending on your reference. Apologies to you standard model devotees. Call it heresy, or at least nonstandard, if you wish.

But, there are no observational examples where time appears to be moving backwards, which places your postulate in the realm of unsupported speculation.

Er, so do you have an actual observation to cite as opposed to theoretical possibilites?

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.

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 dont keep pushing this idea forward. Cosmo
