How many dimensions are our universe formed?Human perception leads us to think that we are evolving in a 4 -dimensional environment.Precisely, three dimensions of space and a dimension of time.The scientific community does not necessarily agree on this point.When some theories are actually based on four dimensions, others, such as string theory, go so far as to imagine a universe at 10, 11, or even 26 dimensions.Today a team of researchers from the University of Mainz is looking for a fifth dimension.According to their hypotheses, the discovery of it could explain the nature of dark matter.
The fifth dimension, possible key to understanding dark matter
Javier Castellano, Adrián Carmona and Matthias Neubert hunt for this fifth dimension.They are looking for "a hypothetical particle which can act as a portal towards a fifth invisible dimension which brings together the cosmic kingdoms of light and darkness".Just that.
The discovery of this hypothetical fifth dimension would answer many questions.The Swedish physicist Oskar Klein declares that "the fifth dimension is invisible for humans, where gravitational force and electromagnetism meet".Thanks to this "portal", scientists could be able to discover the nature of dark matter.This represents one of the current greatest mysteries in our universe.This possibility could allow spectacular advances both from a scientific point of view and in the understanding of the universe.
According to the scientific team, the dark matter could "be transferred since the fifth dimension through portals, creating relics of black matter and firm black matter through the fifth dimension".In reality, dark matter poses a major problem for scientists.We do not know where she is, nor what she is.Only its existence is generally accepted by scientists.Thus, according to the team, "we know that there is no viable candidate in the standard model of physics, so this fact requires the presence of a new physics".
The fifth dimension, a possibility already theorized in physics by the Randall-Sundrum model
In reality, the existence of a hypothetical fifth invisible dimension has already been theorized by the Randall-Sundrum model in 1999.By trying to simplify as much as possible, this theory suggests that we live in a five -dimensional universe.The fifth would be invisible, and made up of particles which could interact with the other four, the gravitons.
Imagine the dimensions of our universe being like the folds of a shower curtain, which scientists call "branes".According to this theory, we would be drops of water that would move in a straight line from one point to another on a brane.Without ever being aware of another brane, nor being able to see it.In parallel, hypothetical particles, gravitons, would be on another brane.These gravitons would be able to partially interact with our Brane, and would be responsible for the gravitational forces.This would explain in particular why gravitational force is lower than electromagnetic strength.It would simply be partially interaction with our brane.Obviously, no one has yet discovered Graviton to confirm this theory.
