Reality the holographic universe – New Scientist

In the holographic universe I discussed the possibility that we, and all around us, may be nothing more than holograms. Surprisingly, many mainstream scientists are currently researching this possibility. Imagine my delight when I discovered in the New Scientist existential issue of 23rd of July covers this very topic.

The paradox of black holes
In his article “Am I a hologram?” Marcus Chown says that indeed the theory of a hologramatic universe is accumulating positive evidence that shows it may actually be correct. The idea apparently is not new. It begins with Stephen Hawking’s work on black holes in the 1970’s. Apparently black holes, as they die, slowly radiate their mass away, without the information that described the original star being present. As physics holds firm to the theory that information cannot be destroyed then this should not be possible. What could be going on?

Information and event horizons
To précis, this paradox is then apparently solved by a Jacob Bekenstein, working at the Hebrew University of Jerusalem. This is all very difficult science, but as I understand it, the premise is that the information content of a black hole is proportional to the two dimensional surface area of it’s, so called, event horizon. An event horizon is the point of no return for falling light or matter. It then gets very complicated, and even involves string theory. It was discovered that the original star’s information could be encoded in tiny lumps and bumps on the event horizon. That is, a 3D object is encoded on a 2D surface, an event horizon.

Hologramatic universe?
This is, after all, basically how a hologram works. If this is possible for a black hole, then it could be possible for the whole universe. The universe is said to have have an event horizon of 42 billion light years. This is because that is the distance beyond which light would not have had time to reach us since the big bang. So we could all be holograms living in a hologramatic universe.

Testing the hypothesis
Strangely any proof rests in the suspected grainy nature of space time. Pixelation should be bigger than expected if a 3D image is hologramatic.
As I mentioned in my “Reality-the holographic universe” post, Mr Hogan at Fermilab is building a dedicated instrument to test this hypothesis. As Marcus Chown remarks; “A positive result would challenge every assumption we have about the world we live in.”

Aspects of reality
Could we really be just a projection from millions of miles away? What could that say about who and what we really are?
