Does dark matter still matter?
Scientists have been searching for dark matter for decades, and think there\u2019s six times more of it in the universe than the stuff we can actually see, like stars and planets. But they still don\u2019t know what it is. So how can we be sure dark matter really exists? And why does it matter, anyway? \n \nBack in 2018, armed with a boiler suit, hard hat and ear defenders, Marnie Chesterton travelled over a kilometre underground into a hot and sweaty mine to see how scientists are valiantly trying to catch some elusive particles \u2013 in the hope of settling things once and for all. \n \nSeveral years on we return to the problem, tackling a few more CrowdScience listeners\u2019 questions about dark matter, and hearing whether we\u2019re any closer to uncovering its mysteries. We\u2019re joined in our quest by Dr Chanda Prescod-Weinstein, physicist and author of The Disordered Cosmos: A Journey into Dark Matter, Spacetime, and Dreams Deferred.
With Professor Malcolm Fairbairn, Dr Chanda Prescod-Weinstein, Dr Chamkaur Ghag and Professor Katherine Freese.
