Unexpected LIGO events and the Mirror World
Revaz Beradze, Merab Gogberashvili

TL;DR
This paper explores the hypothesis that certain LIGO gravitational wave events could originate from mirror world binaries, which are more probable due to earlier star formation and higher matter density in the mirror universe.
Contribution
It proposes a novel explanation for unusual LIGO events by linking them to mirror world binaries, highlighting the increased likelihood in such scenarios.
Findings
Mirror world binaries can account for LIGO events in mass gaps.
Star formation in the mirror world occurs earlier, increasing merger probabilities.
Matter density in the mirror world can be over five times higher than in our universe.
Abstract
We consider the possibility that LIGO events GW190521, GW190425 and GW190814 may have emerged from the mirror world binaries. Theories of star evolution predict so called upper and lower mass gaps and masses of these merger components lie in that gaps. In order to explain these challenging events very specific assumptions are required and we argue that such scenarios are order of magnitude more probable in mirror world, where star formation begins earlier and matter density can exceed 5 times the ordinary matter density.
