Universe Generation from Black Hole Interiors

TL;DR

This paper explores the idea that our universe could originate from black hole interiors, potentially resolving key cosmological problems without relying on inflation, and discusses implications for information loss.

Contribution

It proposes a novel scenario where universe creation from black holes addresses major cosmological issues independently of specific models.

Findings

Horizon problem may be naturally resolved

Flatness problem can be addressed without inflation

Structure formation could occur without a long inflationary period

Abstract

We point out that scenarios in which the universe is born from the interior of a black hole may not posses many of the problems of the Standard Big-Bang (SBB) model. In particular we demonstrate that the horizon problem, flatness, and the structure formation problem might be solved naturally, not necessarily requiring a long period of cosmological inflation. The black hole information loss problem is also discussed. Our conclusions are completely independent of the details of general models.
