**BLACK HOLES AND REVELATIONS**

Black holes
are the source of a major quandary when it comes to our understanding of
physics; either they can destroy information, which contradicts what we know
about quantum mechanics, or they seemingly disregard Einstein’s theory of
relativity. However, it’s now thought by some that the many worlds
interpretation might help explain the situation.

Black holes
have long since presented something of a contradiction considering our current
understanding of physics. Now, the many worlds interpretation offers a
convincing explanation.

It suggests
that each one of the multiple possible outcomes of a quantum event splinters
off into its own discrete world.

Now, a team
of researchers at the California Institute of Technology led by Sean Carroll
has suggested that this interpretation can explain away inconsistencies
pertaining to black holes. They say that general relativity is upheld within
each single possible world, while information is preserved across the entire
global wave function, if not among individual branches.

**MANY WORLDS**

Aidan
Chatwin-Davies, a member of Carroll’s team, told Futurism that other scientists
have already suggested applying the many worlds theory, also known as
Everettian, to the black hole information problem. “Cosmetically, we’re perhaps
the first to cleanly label our perspective as Everettian,” he said. “More
substantively, we wanted to perform some concrete calculations to mathematize
otherwise abstract ideas.”

“Previous
attempts considered statements of general relativity and quantum mechanics to
be applicable to the same world,” Yasunori Nomura, professor of physics at the
University of California, Berkeley told Futurism. “My approach separates the
two – quantum mechanics allows for a quantum state to be a ‘superposition’ of
many classical worlds; statements of quantum mechanics apply to the entirety of
these many worlds while those of general relativity apply only to each of these
worlds.”

This line of
thinking is important because it could potentially explain more about the
nature of gravity and spacetime. Nomura suggests that these ideas have a
broader relevance to how quantum gravity works at a fundamental level,
particular in relation to the origins of the universe.

“We know
that we need both general relativity and quantum mechanics to understand black
holes, and so they are a good starting point for testing out ideas about
quantum gravity,” explained Chatwin-Davies. “If we really understood how to
describe black holes, then we would be a great deal closer to being able to
describe quantum gravity in broad generality.”

By using the
many worlds interpretation, scientists and astronomers are finding new ways to
approach longstanding questions about black holes. With further study, this
research might offer up further information about the very fabric of our
universe that could fill in some persistent gaps in our knowledge.
