Scientists have identified a sub-atomic particle that could have formed the “dark matter” in the Universe during the Big Bang.

Up to 80% of the Universe could be , but despite many decades of study, its physical origin has remained an enigma. While it cannot be seen directly, scientists know it exists because of its interaction via gravity with visible matter like stars and planets. Dark matter is composed of particles that do not absorb, reflect or emit light.

Now, nuclear physicists at the University of York are putting forward a new candidate for the mysterious matter—a particle they recently discovered called the d-star hexaquark.
