And you don't fix something if it's not broken, and as of today there is no evidence that General Relativity is broken. * *By contrast, if there's a way to explain the arrow of time without postulating that the universe started out in a very low entropy state nobody has found that explanation yet; if anybody ever does we can drop that axiom because you should never have more axioms then you absolutely require. * * John K Clark See what's on my new list at Extropolis <https://groups.google.com/g/extropolis>* d'a > > -- You received this message because you are subscribed to the Google Groups "Everything List" group.
