At the footnote of the chapter "Large-Scale Structure of the Universe" in Julian Babour new book The Janus Point is this passage:
"Besides a Janus-point origin, there are now several proposals—involving bouncing universes or ones that expand after a long quasi-stable period—in which the universe does not explode into existence. These have often been created with properties tailored to be rivals for inflation.".
What are the official rivals for inflation? What must be the characteristics of the rivals that can also explain the horizon problem, flatness problem, and the origin of galaxies and clusters of galaxies? (What else?)
