Japanese scientist discovers potential signs of dark matter

• Tomonori Totani has discovered possible signs of dark matter.
• Gamma-ray emissions may indicate its presence in the Galaxy.
• Additional research is necessary to confirm the discovery.

On November 25, 2025, Japanese astronomer Tomonori Totani announced that he may have discovered the first direct signs of dark matter. This discovery is based on data obtained from the Fermi space telescope, which recorded gamma-ray emissions that may indicate the existence of dark matter in the center of our Galaxy.

Dark matter was first hypothesized in the 1930s by Swiss astronomer Fritz Zwicky, who noted that galaxies are moving faster than their mass would allow. It is believed that dark matter makes up approximately 27% of all matter in the Universe, while ordinary matter, to which humans and stars belong, constitutes only 5%.

Totani found that the gamma-ray emissions he observed have similarities to previously predicted characteristics of dark matter. If these results are confirmed, it could be a significant achievement in the search for dark matter. However, according to some scientists, additional research is necessary to rule out other possible explanations for the detected signals.

Totani's research has been published in the Journal of Cosmology and Astrophysics. The scientist emphasized the importance of obtaining confirmation from other regions of the cosmos to strengthen the confidence in his observations.
