A new research paper issued in Physical Review Letters has shown evidence which backups up the theory of a holographic universe that stands up nearly as well as the standard cosmological model presently acknowledged by astronomers. The idea that the universe is a hologram doesn’t suggest that you, your cat, and everything that lies in your daily and experience and understanding, is not real or physical. The holographic principle suggests that all the properties of our three-dimensional (plus time) cosmos are programmed on a two-dimensional surface.
Senior author of the research paper, Professor Kostas Skenderis from the University of Southampton said in a statement:
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. 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.
Physicists tested a sequence of holographic models in contradiction of observations of the very early cosmos made by the European Space Agency’s Planck space observatory. Researchers were able to eliminate some of the models, but others were observed to fulfill the observations.
This is quite a stimulating conclusion as it offers a superior direction for researchers to examine the credibility of the holographic universe theory. The models they tried, however, did marginally worse than the standard model, which suggests that the universe is made of dark energy and dark matter and a minor fraction of visible matter.
Professor Kostas Skenderis said:
Einstein's theory of general relativity explains almost everything large scale in the universe very well, but starts to unravel when examining its origins and mechanisms at a quantum level. Scientists have been working for decades to combine Einstein's theory of gravity and quantum theory. Some believe the concept of a holographic universe has the potential to reconcile the two. I hope our research takes us another step towards this.
The holographic principle was established while studying black holes and it has been also used a lot in string theory.
