It doesn’t even move with lightweight.

The explore for the substance particle has been a probe for scientists since the Nineteen Thirties. Today, there area unit quite one hundred groups around the world grappling with however we will prove it exists.

Astrophysicist Katherine Freese is one in all those that have dedicated their lives to attempting to seek out the solution. Thirty years past, her theories on the existence of dark stars that exert AN invisible influence on the Universe light-emitting diode to the building of particle accelerators underground. within the video higher than, she explains, however, may|we'd |we would} notice these stars – and the way their discovery might modification everything we all know concerning the Universe we tend to sleep in.
