Dark matter could come from the mirror universe, according to physicists

There are many theories about the creation of dark matter: some believe that it is hidden in an extra dimension, others are sure that the mysterious substance was created during a second big bang, and some even fundamentally doubt its existence.

new Stadylocated on the preprint server arXiv It suggests that for every physical interaction in normal matter, there could be a corresponding action in the dark matter world. Exotic matter – so the theory goes – could come from the “dark mirror universe” linked to our universe since the beginning of time.

how Paul M. Sutterastrophysicist from Flatiron Institute In New York, on Live Science ReportsThe study's assumptions are based on two strange coincidences.

Coincidence No. 1: The amount of dark matter and normal matter are at the same level

Coincidence #1: Observations indicate that the amounts of dark and regular matter in the universe are approximately equal.

Dark matter behaves As defined by the Max Planck Institute for Nuclear PhysicsLike ordinary matter, only the form is “dark”. This means that the substance is imperceptible in the visible, radio or X-ray range. However, astronomical and cosmological observations such as the orbital velocities of stars or the kinetic energies of galaxies in galaxy clusters indicate the existence of dark matter.

Although regular and dark matter have completely different properties and operate according to different sets of rules, no matter dominates the other. To explain this fact, researchers have come to the conclusion that there must be a hidden connection.

Coincidence #2: Protons and neutrons have approximately the same mass

Coincidence #2: In ordinary matter physics, protons and neutrons have approximately the same mass. This enables the formation of stable atoms.

But what if protons and neutrons had no practical mass uniformity? In this case, stars and planets, among other things, cannot form.

According to theory, this could apply to the shadow universe. In this mirror universe, the assumption is that subatomic particles may not have much interaction. This would explain why dark matter appears less clumpy.

This study is a work that has not yet been peer-reviewed, and is an addition to existing theories about dark matter. It therefore remains to be seen how the study will be received in the wider world of physics.
