Scientists have recorded a signal of dark matter: what this means for science.

According to ТСН: Scientists have reported the detection of a signal that could become the first direct evidence of the existence of dark matter.

Dark matter was first predicted in 1933 by astronomer Fritz Zwicky when he noticed a lack of gravitational mass in the visible galaxies of the Coma Cluster. Subsequent evidence emerged in the 1970s thanks to astronomer Vera Rubin and her colleagues, who studied the uniform rotational speeds of the outer and inner parts of spiral galaxies. All conclusions were indirect and based on gravitational influences, as dark matter does not emit or reflect light.

Gamma rays and dark matter

One theory suggests that dark matter particles may 'annihilate' upon collision, emitting gamma quanta.

A team of scientists led by Tomonori Totani from the University of Tokyo targeted the Fermi telescope on the central regions of the Milky Way—areas where, according to calculations, there should be the most dark matter. The researchers detected gamma rays with energies around 20 giga-electronvolts, forming a halo-like structure oriented towards the center of our Galaxy.

At this time, new hypotheses by physicist Stefano Profumo exist, according to which dark matter could have formed either in a 'mirror' universe or through quantum radiation of the cosmic horizon during the early stages of cosmic development.

The detection of possible gamma rays associated with dark matter opens new perspectives for studying this mysterious component of the universe. This could be an important step in understanding not only dark matter but also the nature of the Galaxy itself and its origin. Scientists hope that further studies will confirm these hypotheses and reveal even more secrets of the cosmos.
