The multiverse hypothesis or theory holds that a group of multiple
universes (possibly infinite universes) comprise everything that exists: The
entirety of space, time, matter, energy, information, and the physical laws and
constants that describe them. The renowned astrophysicist Neil deGrasse Tyson
explains in detail the multiverse hypothesis.
However, prominent physicists are divided about whether any other
universes exist outside of our own. Some even go as far as to say that the
multiverse is not a legitimate topic of scientific inquiry. Because it can not
be empirically falsified. But Neil deGrasse Tyson among other prominent
cosmologists, thinks that given our understanding of quantum mechanics and the
thoery of General relativity, the possibility of the existence of the
multiverse is a legitimate scientific hypothesis.
Steven Weinberg said that if the multiverse existed, the hope of finding
a rational explanation for the precise values of quark masses and other
constants of the standard model that we observe in our Big Bang is doomed, for
their values would be an accident of the particular part of the multiverse in
which we live.
Some scientists analyzed the data from the Wilkinson Microwave
Anisotropy Probe, an uncrewed spacecraft operating from 2001 to 2010 that
measured temperature differences across the sky in the cosmic microwave
background, the radiant heat remaining from the Big Bang, and claimed they
found evidence suggesting that our universe collided with other parallel
universes in the distant past.
However, a more thorough data analysis from the Wilkinson Microwave
Anisotropy Probe and from the Planck Satellite, a space observatory operated by
the European Space Agency from 2009 to 2013, which mapped the anisotropies of
the cosmic microwave background, did not find any statistically significant
evidence of universe collisions. there was no evidence of any gravitational
pull of other universes on ours either. And to add insult to injury to the
proponents that the multiverse hypothesis has been backed up by statistical
evidence, the Planck satellite, has a resolution three times higher than the
WMA Probe.
Our brains are not evolutionarily equipped to intuitively understand
quantum mechanics and large scale cosmic phenomena. But Neil deGrasse Tyson
with his usual wits explains the multiverse hypothesis in layman's terms.
