Dark matter is a mysterious substance that physicists believe makes up most of the universe. At the same time, dark matter cannot be detected using direct observations, only its gravitational effect on ordinary matter, writes futurism.com.
Over the decades, this hypothetical material has spawned a slew of theories.
For example, it is believed that dark matter hides an extra dimension, was created as a result of the second Big Bang, or is an information layer. There are also skeptics who completely refute the existence of dark matter.
Astrophysicist Paul Sutter of the Flatiron Institute has put forward another exotic theory about dark matter new paper.
He suggested that dark matter resides in a warped mirror universe in our own. The difference between the two is that atoms could be formed in our universe.
According to the astrophysicist, his theory is based on a number of intriguing coincidences. Available observations indicate that roughly comparable amounts of normal and dark matter exist, with a slight preference for dark matter.
Second, neutrons and protons have almost the same mass, which allows them to form stable atoms – another arbitrary but extremely important property. Otherwise there would not be a single star, planet or ourselves in our universe.
Based on this, the new theory proposes that there exists a shadow universe in which neutrons and protons have no mass symmetry, meaning that only a ‘soup’ of subatomic particles exists in this dimension. They interact little with each other, which explains why dark matter doesn’t seem to clump together much.
The new paper, which has not yet been peer-reviewed, is yet another theory attempting to explain the long-standing mystery of dark matter.
