Study: our universe may be one big hologram

We live in a giant hologram and everything we see around us is only a projection of a two-dimensional surface. This theory was proposed in 1997 by the Argentinean physicist Juan Maldacena.

Most people know holograms of credit cards and bank notes. They are two-dimensional, but the eye is three-dimensional. Our universe behaves in a similar manner.

Austrian scientists have for the first time demonstrated that the holographic principle also works in a realistic model of our cosmos.

According to the holographic principle, there is a two-dimensional surface that we can not see. This surface contains all the information necessary to describe a three-dimensional object, in this case our universe.

Data containing the description of a 3D object, such as the device that you read this article, can be hidden in a field in these flat, “real” version of the universe.

Maldacena came to this conclusion when he discovered that for mathematical descriptions of the universe one dimension less is needed than you would expect.

Until now, this principle was only tested in anti-de-sitter spaces (ADS), a space-time continuum that is negatively curved. The problem is that they are very different from the spaces in our own universe.

Scientists at the Vienna University of Technology have now discovered that the holographic principle holds out in a flat space time. While this does not prove that we are in a hologram life, the research does suggest more and more in that direction. The study is published in Physical Review Letters.
