@ninjacolin I cannot prove you are wrong, but you can’t prove I am either. :-)
@RealEyesRealizeRealLies That’s an interesting point. For questions like this, it works best to think in thought experiemnt mode. So let’s allow a disembodied, intelligent point to be there in the far future to observe a universe approaching infinite entropy. Could that be the trigger of the next big bang. Quantum mechanics says it absolutely could—in fact, some top physicists assert that nothing else could possibly result. That gets us pretty close to your human body analogy. We’re still here, but none of what we were made of 7 years ago is here with us now.
@YARNLADY Amen to that.
@rexacoracofalipitorius The Big Bang isn’t a postulate, it’s a legitimate theory. The postulate predicted a large number of things, all of which have been independently confirmed by thousands of observers, many intent on proving the postulate wrong. The existence of the Cosmic Microwave Background Radiation, its exact temperature, its structure and location all flowed from relativistic equations calculating what would remain if there were a big bang.
I don’t know of any credentialed cosmologists who still subscribe to the cyclical expansion/contraction postulate. That’s been ruled out. But a big crunch is not the only thing that that could conceivably initiate another Big Bang. What appears to be a pure vacuum is actually a seething, boiling cauldron of quantum fluctuations in which particles poof into and out of existence continually at a bewilderingly rapid rate. So enough entropy could be just what it takes to touch of the next Big Bang. If so, then previous entropy of a Universe dying heat death might have triggered our Big Bang.
