Why The Multiverse Might Not Just Be a Marvel Fictional Concept?

Do other universes even exist?

Transcript

00:00Mankind has long looked towards the cosmos in search of life elsewhere in the universe,

00:08but now experts say we might be thinking about the whole thing all wrong.

00:12While space travel may have been impossible for the generations that came before us, multiverse

00:16theory has become a theoretical, albeit possible, endeavor now.

00:20Astrophysicist Geraint Lewis writes for The Conversation,

00:22The basic premise is that new universes crystallize out of the Big Bang expansion, each verse

00:27in this multiverse possibly even having its own laws of physics.

00:30Now they say, what if our search for life didn't look vertically up to the stars, but

00:34rather horizontally to these parallel multiverses?

00:37Well according to Lewis, that means we have to break down the fundamentals of what life

00:41needs.

00:42We know we need water and oxygen to survive, but when breaking that down to the fundamentals,

00:46that means we basically need to be within a particular proximity of a star.

00:49All elements we need come from that source, but that source needs massive amounts of gravity

00:53to produce extreme temperatures, and densities for star formation.

00:57Electromagnetism is a force then required to ignite a star in a nuclear reaction.

01:01Now experts need to figure out which theoretical universes could not only exist, but which

01:05ones might be habitable, allowing humanity to perhaps find life, or even a new place,

01:10for us to live.
