On the conformal cyclic evolution of the universe, two ideas are proposed. With the help of loop quantum gravity, loop quantum cosmology and conformal cyclic cosmology these postulates are proven to exist. To support the postulates a full universe hypothesis is also proposed. Without facing big rip singularity, a phantom dominated conformal cyclic universe is discussed. The article is written in simplest possible manner for everyone to understand it.

Report 1 by Rathinam Chandramohan on 2021-12-16 (Invited Report)


The author proposed two Cosmological postulates based on conformal cyclic cosmology. He has correlated loop quantum gravity and conformal cyclic cosmology in this work.

But For these postulates, proofs sketched by the authors is unsatisfactory.

The following questions arises which are not addressed.

1. Is there any possible consequences from string theory in this model?
2. In postulate 1, the authors suggested that the big bang may not be the actual beginning of the universe. But how does the time-reversal happen beyond t<0?
3. What is the role of inflation in these postulates?

The work " Proposals on Conformal Cyclic Evolution of The Universe " is rejected for publication in SciPost.
