Black Holes: Saviours of the Universe?
In terms of what might be called \u201cpure science\u201d, there\u2019s one topic that tends to get people excited, and that's black holes. A few weeks ago, in February 2023, a pair of papers came out that linked theories about black holes to dark energy \u2013 something we really don\u2019t understand. If correct, this could mean that black holes, by their very nature, could explain the accelerating expansion of the Universe. Black holes, of course, are often mis-understood. To find out a little more about them, Chris spoke to Dr Becky Smethurst, from University of Oxford. We also get into a few of the details about what the research suggests might be is going on, with lead author Dr Duncan Farrah from the University of Hawaii. Finally, it's back to Becky, who is sceptical about these new results.
