Neutrinos provide insight into why matter dominates the universe, celebrating the Hubble Space Telescope’s 30th birthday

23 Apr 2020 Hamish Johnston

One of the enduring mysteries of physics is why the universe appears to contain much more matter than antimatter. An important clue has just been unearthed by the T2K experiment in Japan, which found a difference in what happens to muon neutrinos and antineutrinos as they travel through nearly 300 km of solid rock. In this episode the Durham University particle physicist Silvia Pascoli discusses the implications of the T2K result with Physics World’s Hamish Johnston.

Tomorrow (24 April) is the 30th anniversary of the NASA’s Hubble Space Telescope and the astronomy writer Keith Cooper has done a series of blogs for Physics World describing his favourite images. In the podcast he joins Margaret Harris for a lively chat about all things Hubble. Their wide-ranging discussion begins with how the telescope was saved from ruin in its early days and ends by pondering the mission’s future.
