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 center of the Milky Way has puzzled researchers for decades. They have tried to determine whether the light comes from colliding particles of dark matter or quickly spinning neutron stars.
According to new research published in the journal Physical Review Letters, both theories are equally likely. If the excess gamma light is not from dying stars, it could become the first proof that dark matter exists.
The mysterious glow could be a compelling clue in the ongoing hunt to prove the existence of dark matter.
The research may tilt the scales for competing theories about excess gamma ray light at the center of the galaxy.
