Gamma rays emerging from neutron stars at the hearts of supernova explosions could solve the mystery of dark matter — in just 10 seconds. That is, if dark matter is composed of axions, which are hypothetical lightweight particles that are currently the leading candidates for dark matter.
The University of California, Berkeley team behind this theory thinks that if it's true, a supernova erupting close enough to Earth would allow us to detect its emissions of high-energy light, confirm the mass of axions and therefore wrap up the whole dark matter puzzle.
