00:04Mankind has long looked towards the cosmos in search of life elsewhere in the universe,
00:09but 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,
00:16multiverse theory 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,
00:26each verse in 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,
00:34but rather horizontally to these parallel multiverses?
00:37Well, according to Lewis, that means we have to break down the fundamentals of what life needs.
00:41We know we need water and oxygen to survive.
00:44When 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,
00:51but that source needs massive amounts of gravity to produce extreme temperatures
00:54and 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,
01:05but which ones might be habitable,
01:06allowing humanity to perhaps find life or even a new place for us to live.
