The quest to understand dark matter remains a challenging puzzle for scientists worldwide. They are now considering alternative explanations for why it remains undetected.
One intriguing hypothesis suggests that dark matter might exist in a parallel “dark mirror” universe. This universe, unlike ours, did not see the formation of atoms after the Big Bang.
According to this theory, every event in our universe is mirrored by a corresponding event in the dark matter universe. This concept introduces a new form of symmetry across universes.
The notion of a “dark mirror” universe might sound like something out of a science fiction story, complete with authoritarian officers and distinctive facial hair. However, this theory is a serious scientific proposition aimed at solving the mystery of dark matter, which is believed to constitute about 85% of the universe’s mass.
Various theories have been proposed to explain the elusive nature of dark matter. Some suggest it could be the result of a second big bang, while others propose it as a self-interacting particle linked to a dark force. Theories also explore the possibility of axions or particles hidden in extra dimensions as potential explanations. Despite the lack of direct evidence, scientists are exploring a wide range of ideas. A recent study suggests that dark matter might be hiding in a “dark mirror” universe where atomic formation failed to occur.
This paper is not the first to propose the existence of a “mirror” universe as a potential hiding spot for dark matter. Researchers from the University of Toronto have theorized the possibility of observing “dark matter” stars from such a universe if they contain normal matter clusters. These mirror stars, if they interact with the gas in a nebula, could reveal themselves through their unique gravitational influence on normal matter. However, the longevity of dark matter stars post-Big Bang is still a topic of debate among scientists.
Thus, the search for dark matter, whether in our universe or a parallel “dark mirror” one, continues as a complex game of hide-and-seek.
