A Holographic Universe
Throughout the years,
lots of theories on what our universe looks like have been formulated.
However,
recent studies conducted by Hyakutake and his colleagues in Ibaraki University
in Japan have strengthened (but not proved) the theory that our universe is
only a holographic projection. The holographic principle is a property of the
string theory that was first proposed by Gerard ‘t Hooft. The theory states that
the universe is a two-dimensional painting on the cosmological horizon and the
third dimension that we are able to perceive comes from the holographic
projection of the flat version of the universe.
When I
first read the article about the holographic universe, my first thought was:
are we real? If we are just holographs from a two-dimensional version of
ourselves, what makes us different from the cartoon characters we see on
television like Peter Griffin and Homer Simpson? It was really hard for me to
digest this information.

Upon
further understanding of the article, I found that the Holographic model of the
universe made a lot of sense. At black holes, there exists an inconsistency
between Albert Einstein’s theory of gravity and quantum physics. The
holographic principle was able to solve this conflict. Juan Maldacena (the one
who proposed a model of the universe where the gravity comes from infinitely
and vibrating thin strings) and Leonard Susskind (one of the first scientists
to propose the holographic principle) were thrilled to know that their theories
now have compelling evidence that support them.
