An international team of physicists proposes a new link in the theory of dark matter , a type of matter that would explain certain behaviors observed in our cosmos, such as the way light bends as it moves from far away places to reach our ground-based telescopes.
In their article published in the journal Physical Review Letters , the researchers suggest that dark matter comes from ordinary or regular matter and that dark matter is capable of creating more dark matter from this matter, which makes up 3-5% of everything in our universe.
According to the work, at some point, dark matter particles began to produce more dark matter particles from ordinary particles, and new dark matter particles were also able to create new dark matter particles from ordinary particles. What looks like a tongue twister shows that there would be nothing left in the universe except dark matter particles. And the reason this is not the case is because of the rapid expansion of the universe.
The expansion slowed the conversion of regular matter into dark matter, leaving us with the amount that is believed to exist today.
