There was a time when there was controversy relating to Big Bang, Steady State, & Alternating Bangs/Crunches. I was fond of Steady State & sorry when it lost out to the Big Bang. I do not remember why Bang Crunch lost to the Big Bang. Steady State aka Continuous Creation was my favorite. It was given up when Quasars were discovered. They were from the distant past; None were more recent than circa 5-6 billion years. Steady State predicted a universe which was unchanging except for small details.
