hey there welcome to life noggin ooh 3d huh oh it went away according to marvel's doctor strange
the multiverse is a concept about which we know frighteningly little but it's not just a brain
breaking concept in marvel movies it's a brain breaking concept in real life too so what exactly
is the multiverse the multiverse refers to a hypothetical group of multiple universes which
means that our universe which includes all that we can see 14 billion light years in all directions
may not be the only one while some physicists have serious doubts about this possibility
others have many theories as to how this could be possible. one physicist and cosmologist Max Tegmark
arranged these theories into a hierarchy that gets progressively weirder in the first level
it's assumed that space is infinite expanding far beyond our own universe in theory this area
could contain parallel universes with the same physical laws as ours and because this region
is so expansive it's possible that things repeat leading to doppelgangers in level 2 there are an
infinite number of level 1 multiverses that exist in the same space time but may have different
physical laws according to the external chaotic inflation and cosmic inflation theories parts
of our universe are continuously expanding these pockets then sort of pinch off from our universe
becoming their own universes. Level 3 is perhaps the most popular in science fiction it's the many
worlds theory where new universes branch off from others whenever multiple outcomes could occur from
an event like the flipping of a coin or making any decision. this stems from a theory in quantum
mechanics called the copenhagen interpretation which says that a quantum particle doesn't exist
in one state or another but in all possible states known as a superposition that is until
it's observed. before then all the possible states of existence make up what we call a
wave function but when the particle is observed the wave function collapses and the particle
is forced into one state however in the many worlds theory there is no wave function collapse
every possible state exists just in different universes finally we have the level 4 multiverse
here anything is possible universes could exist anywhere have different cosmological properties
quantum states, and physical laws making them impossible to visualize although the animator
is still trying which shout out to you animator the basis for this theory is math. Any mathematical
structure that can be studied describes some sort of existing universe. Scientists have actually been
looking for physical evidence of other universes for instance collision remains of our universe
with another could appear as distortions in the cosmic microwave background or special black holes
could exist as the remains of pocket universes breaking off from our own so far no evidence
has been found and no multiverse theory has been proven, so while doctor strange may get to explore
the multiverse we'll just have to wait and see what's out there alright let's see what else is on
