Our universe may be a vast and complex 2D hologram
British, Canadian and Italian scientists have found the first evidence that our world is not what we thought it was. The astrophysicists studied the “afterglow” left over from the Big Bang, or the cosmic microwave background and found substantial evidence that the universe is holographic.
The concept of a holographic universe was first suggested in the 1990s. But it’s not until now that telescope data has been able to back it up.
The concept is similar to watching a 3D film in a cinema. Actually, Viewers see the pictures as having height, width and, crucially, depth when in fact it all originates from a flat 2D screen. The difference is that, in our 3D universe, we can touch objects and the “projection” is “real” from our perspective.
It’s a mind-blowing theory, we perceive everything around us to be 3D when they are actually flat, the theory suggests.
In recent decades, advances in telescopes and sensing equipment have allowed scientists to detect a vast amount of data hidden in the white noise or microwaves left over from the moment the universe was created.
Professor Kostas Skenderis, of mathematical sciences at the University of Southampton, said that, “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.”
He also said that, “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 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,” he added.
The researchers, from the University of Southampton (UK), University of Waterloo (Canada), Perimeter Institute (Canada), INFN, Lecce (Italy) and the University of Salento (Italy), have published their findings in the journal Physical Review Letters.
