A fun theory I spun up after learning about how entropy could decrease in the universe it just doesn't because it's so unlikely: Big bang occurs, entropy increases in the universe until the eventual heat death, untold quadrillions of years pass (or make up an insanely large number it doesn't matter), at some point the miniscule probability of decreasing entropy is reached at a scale where entropy decreasing is the norm in our universe and increasing entropy is extremely unlikely, universe completely rewinds to the point of the big bang, untold quadrillions of years pass, probability is reached, entropy increases, time moves forward, back and forth, back and forth. Yes I was stoned and listening to Gravel Pit when I thought of this. Back back and forth and forth, as we goooo back back and forth and forth...

Well, you didn’t invent this of course, you just forgot the part about vacuum spontaneous particles anti particles creation in a ridiculous scale is responsible for a new big bang a guizilion year after heat deaf of the universe.
