Researchers from Johns Hopkins University may have found a clue to prove the existence of dark matter.
A diffuse glow of gamma rays near the Milky Way's center has puzzled researchers for decades. They have tried to determine whether the light comes from colliding dark matter particles or quickly spinning neutron stars.
New simulations suggest that both theories are equally likely, according to research published in Physical Review Letters.
If excess gamma light is not from dying stars, it could become the first proof that dark matter exists.
