A new study published in the Monthly Notices of the Royal Astronomical Society has revealed an unexpected behavior in primordial black holes (PBHs). Scientists found that PBHs, which were formed in the early universe, may have been frozen in time due to the extreme density of the universe in its earliest stages.

This phenomenon could have a major impact on our understanding of the universe and the role of dark matter. PBHs are believed to be small, dark objects that formed in the first moments after the Big Bang. While they are incredibly small, they are thought to make up a significant amount of the universe’s dark matter.

Until now, scientists believed that PBHs could grow over time as they absorb more and more matter. However, this new study suggests that PBHs may have been frozen in time due to the extreme density of the early universe. This could mean that PBHs may have stayed the same size since the Big Bang, and may have played a more influential role in the formation of the universe than previously thought.
