As noted on the website Wall Street Pit, “a group of astrophysicists have found evidence that suggests a holographic universe is just as feasible as conventional theories about the origin of the universe.
As reported by Phys Org, a collaborative study involving researches from Canada, Italy and the UK may have provided the first detectable evidence indicating that our universe may in fact be a ‘vast and complex hologram’. It’s an idea that’s been around since the 1990s — that everything we see around us exists on a flat, 2D surface, but we see everything in 3D because the universe acts like one giant hologram.
To explain the concept better, the common analogy used is to imagine the holographic universe as if you were watching a 3D movie in a movie theater. As movie-watchers, we see images on the screen as having height, width, and depth, even if they’re being projected on a 2D screen. In the case of our universe, it’s a bit more complicated because we can’t just see things, we can touch things too, which makes our perceptions ‘real’.
A holographic universe is a concept that appeals to physicists because it can potentially reconcile inconsistencies between quantum mechanics and Einstein’s theory of general relativity. Because although Einstein’s theory can explain large-scale aspects of the universe, it breaks down at quantum levels. In other words, it can’t explain quantum mechanics. And that just won’t do when describing what the early universe was like.
According to the researchers, proof for their theory can be found in the Big Bang’s ‘afterglow’ or its cosmic wave background. Through telescopes, they were able to detect a huge amount of data hidden in the afterglow following the beginning of the universe. They then compared this data with data from quantum field theory.
What they found was that their equations appeared to reconcile irregularities between the Big Bang afterglow and quantum physics. And the only explanation for the universe working the way it does is that it must have been a hologram at that time, meaning, during the early stages when the universe was being formed, everything was being projected in 3D from 2D boundaries.
As University of Southampton Mathematical Sciences Professor Kostas Skenderis said: ‘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.’ [See his lecture on this subject here].
What exactly does the concept of a holographic universe mean for us? It might not have a direct impact that we can feel. But if it’s true, it will pave the way for the unification of two conflicting theories — general relativity and quantum mechanics. And that will in turn lead to a better understanding of how the universe began, and how time and space came about. Findings of the study have been published in the journal Physical Review Letters.”
