Some scientists, who conducted a new study published in the academic journal Physical Review Letters, came up with a very interesting theory. Researchers stated that they think there is a ‘mirror world’ that affects gravity in our universe, although there is no information about what it looks like.
This study, published by three researchers, is based on problems with the Hubble Constant. If you ask what is the Hubble Constant; Named after the famous astronomer Edwin Hubble, this concept is called the constant number representing the expansion rate of the universe. However, studies on the subject may lead to different results for this constant.
Hubble Constant mismatch may be due to a ‘mirror world’ we can’t see
In a recently published study, scientists aimed to investigate the reason behind the discrepancy in the constant. Experts stated that the reason for this may be a ‘mirror world’ consisting of particles we have not yet seen. In the explanations regarding this hypothesis, “In most of the observations we make in cosmology, we point out that the universe as a whole contains a natural symmetry in the case of rescaling. “This may provide a way to understand why there is a discrepancy between different measurements of the expansion rate of the universe.”
According to the explanations, researchers discovered a mathematical feature that had not been noticed before in standard cosmological models. It was stated that this allows for a higher expansion rate and hardly changes the other predictions in the standard model. The study revealed that a uniform scaling of the gravitational freefall velocity and the photon-electron dispersion velocity does not alter most dimensionless cosmological observations.
So, experts tackled the discrepancy in the Hubble Constant by trying to create a model that does not violate the cosmological rules learned so far. It was stated that the use of this symmetry by the universe in some way may indicate the existence of an invisible mirror world, where we can only see the gravitational effect. It was stated that this ‘mirror earth’ would allow the scaling of the free fall rates, while not violating the average photon density measured exactly today.
Finally, researcher Francis Yan Cyr-Racine said that this is a parallel universe with copies of particles, adding: “This may seem crazy; however, these mirror worlds have an important physics literature. Our work also links this vast literature to a very important problem in cosmology.”
