Edward Witten and the Mathematical Multiverse?

[Suekdccia]

TL;DR Summary

Has Edward Witten made any theory or model that proposes (or is compatible with the proposal) that all mathematically possible universes exist (as Max Tegmark did)?

Physicist Max Tegmark proposed that every mathematically possible universe exists [1]. According to Tegmark himself, when he published such ideas, he received mostly positive feedback from Edward Witten and David Vogan [2].

Due to this, I was wondering whether Witten has made reference to Tegmark's work in any of his papers or talks?. Or, to put it in another way, I was wondering if Witten has made any model or theory in any of his works that would be compatible with this hypothesis that every mathematically possible universe may physically exist?[1]: https://arxiv.org/abs/0704.0646

You can check on scholar.google Tegmark's paper and see who has cited it. If Witten has done something on the topic, most likely he would have cited Tegmark.

That depends upon whether the Kosmos is exogenous or endogenous...if the latter, no--every imaginable mathiverse could not exist.
