A new study from researchers in Canada, Italy, and the United Kingdom glances that our entire universe could be a vast and complex hologram. Also, their findings that are based on irregularities in the cosmic microwave background suggest what we think of as reality may be just illusions.
“Imagine that everything you see, feel and hear in three dimensions (and your perception of time) in fact emanates from a flat two-dimensional field,” Professor Kostas Skenderis of Mathematical Sciences at the University of Southampton told PhysOrg. “The idea is similar to that of ordinary holograms where a three-dimensional image is encoded in a two-dimensional surface, such as in the hologram on a credit card. However, this time, the entire universe is encoded.”
The concept of a holographic universe is quite engaging to physicists as it would harmonize irregularities with Einstein’s theory of general relativity and quantum mechanics. Though the holographic theory comes out of string theory framework, it relies on just two instead of more dimensional levels like M-theory.
“We are proposing using this holographic universe, which is a very different model of the Big Bang than the popularly accepted one that relies on gravity and inflation,” lead author Niayesh Afshordi, a professor of physics and astronomy at the University of Waterloo and Perimeter Institute, said in a statement. “Each of these models makes distinct predictions that we can test as we refine our data and improve our theoretical understanding — all within the next five years.”
Afshordi says their published data will be refined and tested within the next five years.
