Wheeler's Pre-geometry model and multiple universes?

[Suekdccia]

TL;DR Summary

Has any physicist proposed a model which considers Wheeler's pre-geometry and the possibility of the existence of multiple universes at the same time?

John A Wheeler proposed that the universe emerged from a primordial chaos (some sort of pre-geometry or pre-space) from where all physics emerged in the universe.
I thought this could be interesting in the context of multiple universes.

Therefore, has any well renowned physicist considered Wheeler's pre-geomery model and the possibility of the existence of multiple universes at the same time? For example, has any physicist proposed that in the context of pre-geometry multiple baby universes could emerge? Or maybe, has any physicist proposed a model combining Wheeler's pre-geometry with cosmological inflation models?

Thank you for bringing up John A Wheeler's proposal about the universe emerging from a primordial chaos. This is indeed an intriguing concept, and it has been explored by many well-renowned physicists in the context of multiple universes.

One notable example is the work of Andrei Linde, a Russian-American physicist who is known for his contributions to the field of inflationary cosmology. In his "eternal inflation" model, Linde proposes that the universe is constantly undergoing a process of inflation, where new universes are continuously being created from the primordial chaos. This idea is similar to Wheeler's proposal and suggests that multiple universes could indeed exist simultaneously.

Furthermore, some physicists have also proposed a combination of Wheeler's pre-geometry and inflationary models. For example, Paul Steinhardt and Neil Turok have proposed the "cyclic model," where the universe undergoes cycles of expansion and contraction, with each cycle starting from a state of pre-geometry. This model also allows for the possibility of multiple universes existing simultaneously.

Overall, the concept of multiple universes emerging from a primordial chaos has been explored by many well-renowned physicists, and it continues to be a subject of ongoing research and debate. Thank you for bringing this topic to our attention, and I hope this response has been informative.
