Exactly. Before dark matter/energy were discovered to be accelerating expansion. There was a prevailing/plausible theory that the universe may endlessly cycle through Singularity > Big bang > Expansion > Contraction > Singularity > Big bang etc due to gravity.
This isn’t a new theory at all, this was first proposed not long after the BBT was.
