Is the present acceleration of the Universe caused by merging with other universes?

TL;DR

This paper proposes that the current acceleration of the Universe can be explained by merging with other universes, leading to modified Friedmann equations that eliminate the need for a cosmological constant.

Contribution

It introduces a novel model where universe merging modifies cosmological equations, offering an alternative explanation for acceleration.

Findings

Modified Friedmann equations derived from universe merging

Explains acceleration without cosmological constant

Provides a new perspective on multiverse interactions

Abstract

We show that by allowing our Universe to merge with other universes one is lead to modified Friedmann equations that explain the present accelerated expansion of our Universe without the need of a cosmological constant.
