Summary

However, according to some advances, it would now be impossible to assume "an infinity of universes in the past", despite the many theories pointing in this direction. This is the position of Michel-Yves Bolloré and Olivier Bonnassies after their three-year survey of renowned scientists for their bestseller Dieu, la science, les preuves (2021).

Quotes

“the work of Hawking and Penrose at the end of the 20th century led to the demonstration of "singularity theorems" establishing that every universe must include an initial singularity. A few years later, in 2003, Alan Guth, Arvind Borde and Alexander Vilenkin established in a theorem the absolute necessity of a global "initial singularity": (...) "Cosmologists can no longer hide behind the possibility of an eternal universe in the past. There is no way out; they must face up to the problem of a cosmic beginning." (A. Vilenkin, Many Worlds in One, Hill and Wang, New York 2006, p. 176). It now also seems established by cosmology that an infinity of cycles in the past is impossible.”
