Creation Moment 11/21/2025 - The yoyo universe nonsense

Yes, they knew God, 
but they wouldn’t worship Him as God 
or even give Him thanks. 
And they began to think up foolish ideas of what God was like. 
As a result, their minds became dark and confused. 
Romans 1:21 NLT

"Oscillating (yoyo) universe ideas were popularized by atheists like the late Carl Sagan and Isaac Asimov, solely to avoid the notion of a beginning, with its implications of a Creator

But the laws of thermodynamics undercut that argument, as each one of the hypothetical cycles would exhaust more and more usable energy. 

This means every cycle would be larger and longer than the previous one, so looking back in time there would be smaller and smaller cycles. 
So the multicycle model could have an infinite future, but can only have a finite past. 
Also, there is far too little mass to stop expansion and allow cycling in the first place, and no known mechanism would allow a bounce back after a hypothetical ‘big crunch’."
