TL;DR
This paper discusses the multiverse concept arising from cosmic inflation, exploring its origins, potential observational tests, and implications for the universe's beginning and end.
Contribution
It introduces a new cosmological worldview based on inflationary bubble formation and discusses possible ways to empirically test this multiverse hypothesis.
Findings
Most bubbles are beyond observational reach
Inflationary multiverse impacts cosmological theories
Potential observational signatures are proposed
Abstract
Recent developments in cosmology suggest that much of the universe is in a state of explosive, accelerated expansion, called inflation. We live in a "bubble" where inflation has ended, and other bubbles with diverse properties are constantly being formed. Most, if not all, of these bubbles are beyond our cosmic horizon and cannot be directly observed. I discuss the origin of this new worldview, its possible observational tests, and its implications for the beginning and the end of the universe.
