Dark Matter May Be Transforming Into Weird Particles That Fill the Universe with Gravity

Physicists have proposed a new indirect way to hunt dark matter: it could decay into hypothetical gravitons that then convert into gamma rays in cosmic filament magnetic fields.

The mechanism relies on the Gertsenshtein effect and shifts the search away from galactic centers toward the large-scale cosmic web.

Researchers suggest looking for an unexpected gamma-ray excess in data such as from the Fermi Gamma-ray Space Telescope.

If confirmed, the idea could open a new observational path to dark matter and offer a possible clue about gravitons.
