It’s a cosmic mystery! Up to 80 per cent of the Universe could be invisible ‘dark matter’ - but despite decades of scientific research, astronomers are still searching for clues.
Composed of particles that do not absorb, reflect or emit light, dark matter cannot be seen directly. But scientists know it exists because of its interaction via gravity with visible matter like stars and planets.
In this special live episode of the Syzygy podcast, York astronomer Emily Brunsden and her co-host Chris Stewart delve into the dark matter enigma with nuclear physicists Mikhail Bashkanov and Dan Watts.
Mikhail and Dan are part of a team at the University of York that recently put forward a new candidate for the mysterious matter - a particle they discovered called the d-star hexaquark, possibly created in large quantities soon after the Big Bang.
Could this exciting new discovery unlock the secrets of dark matter? Join us to find out more!
