The coincidence problem and the Swampland conjectures in the Ijjas-Steinhardt cyclic model of the universe
In the Ijjas-Steinhardt cyclic model, the universe passes through phases dominated by radiation, matter, and a dark energy scalar field, with the value of the scale factor increasing with each cycle.Since each cycle terminates in a finite time, it is straightforward to calculate the fraction of time click here that the universe spends in a state fo
