Astronomers think there should be 5 times as much dark matter as ordinary matter – a shadow universe that makes up most of the mass in the universe. But after decades of trying, no experiments have found any trace of dark matter – except one.

A massive thanks to the wonderful people at the ARC Centre of Excellence for Dark Matter Physics for showing us around and being on camera – Fleur Morrison, A/Prof Phillip Urquijo, Prof Elisabetta Barberio, Madeleine Zurowski and Grace Lawrence.
Thanks to Leo Fincher-Johnson and everyone at the Stawell gold mine for having us.
Massive thanks to Prof. Geraint Lewis – Geraint has been Veritasium’s go-to expert for anything astrophysics and cosmology related. Please check out his website, and buy his books, they’re great –
Thanks to Prof. Timothy Tait for the help to make sure we got the science right.
