For decades, science and the average person have both rightfully theorized that the universe is three-dimensional. With vast research having supported this for quite some time, there had been no reason to second-guess this theory. However, recent calculations have now shown that this original theory may not be the best way to sum up the universe. And that, as a matter of fact, the universe actually requires fewer dimensions than previously calculated.
Up until now, three-dimensional space was how we knew to describe the universe. However, recent studies suggest that the universe may actually exist in two dimensions, albeit holographically so. This newly revisited calculation is called the “holographic principle” which asserts that a mathematical description of the universe actually requires one fewer dimension than it would have previously seemed.
Although this principle hasn’t been widely studied within the science community up until this point (although it has in smaller scientific communities), it has now brought light to a previously closeted angle.
The theory suggests that although the universe may appear as three-dimensional to you and I, it only requires two dimensions. “In 1997, the physicist Juan Maldacena proposed the idea that there is a correspondence between gravitational theories in curved anti-de-sitter spaces on the hand and quantum field theories in spaces with one fewer dimension on the other”, says Daniel Grumblier (TU Wien, Vienna).
This theory has been calculated twice now with the same result happening each time. This is good news, and shows that the principle can hold strong in stringent scientific testing environments. “If quantum gravity in a flat space allows for a holographic description by a standard quantum theory, then there must be physical quantities, which can be calculated in both theories – and the results must agree”, exclaims Grumillers.
“This calculation affirms our assumption that the holographic principle can also be realized in flat spaces. It is evidence for the validity of this correspondence in our universe”, another physicist, Max Riegler of the same team explains.
As much evidence that has been pouring in from their studies, this doesn’t, however, proven that we indeed live in a two-dimensional, holographic universe – rather than a three-dimensional once. But with some more research and proper calculative studies behind this hypotheses and we may soon reposition what we know about the universe we live in.
