Unveiling the Cosmic Mystery: Dark Matter May Originate from Primordial Black Holes
A groundbreaking theory suggests that dark matter, the unseen substance making up 85% of the universe, could be composed of black holes from a previous cosmic cycle, shedding new light on the origins of our universe.
In a remarkable development, scientists have proposed a novel hypothesis that dark matter, the elusive substance that makes up the majority of our universe, may have its origins in a previous cosmic cycle. This intriguing theory, based on the model of a cyclic universe, could provide valuable insights into the nature of dark matter and the formation of our universe as we know it.
The concept of a cyclic universe, which suggests that the universe expands and contracts in an endless cycle, has long been explored by cosmologists. Now, a team of researchers has taken this idea a step further, hypothesizing that the black holes formed in a previous cycle could be the key to understanding the mystery of dark matter.

This intriguing proposition challenges the traditional view that dark matter is composed of undiscovered subatomic particles, opening up a new avenue of exploration for scientists.
"If this model is correct, it would mean that dark matter is not made of the same stuff as the ordinary matter we're familiar with," explained one of the study's authors, Tommi Tenkanen, a postdoctoral fellow at Johns Hopkins University. "Instead, dark matter consists of the remnants of black holes from the previous cycle of the universe."

This would explain the elusive nature of dark matter, as these black holes would not interact with ordinary matter in the same way as hypothetical subatomic particles.
"One of the nice things about this model is that it can be tested," Tenkanen said. "We predict certain signatures from primordial black holes that we can look for to see if this model is correct."

As the scientific community continues to grapple with the mysteries of the cosmos, this innovative theory offers a tantalizing new perspective on the fundamental nature of our universe.
