Conformal Cyclic Cosmology (CCC) is a scientific theory and cosmological model advanced by the physicist Sir Roger Penrose.[1] In CCC, the universe undergoes a repeated cycle of death and rebirth, with the horizon at infinity of each previous universe being identified with the Big Bang singularity of the next.[2]
In 2010, Penrose and V. G. Gurzadyan published a preprint of a paper claiming that observations of the cosmic microwave background observed by the WMAP satellite were consistent with his CCC hypothesis, with a low probability of the null hypothesis that the observations in question were caused by chance.[3]
