Back in 2019, the gravitational wave observatories LIGO and Virgo detected major ripples in spacetime. While astronomers generally agree that the event, dubbed GW190521, was the result of two black holes colliding, a team of researchers at the Chinese Academy of Sciences has proposed a far more eyebrow-raising explanation. As detailed in a yet-to-be-peer-reviewed paper, first spotted by ScienceAlert, the researchers suggest that LIGO and Virgo instead picked up the signals of a black hole collision in a different universe than ours.

Imagine that someone gives you a list of five numbers: 1, 6, 21, 107 and-wait for it-47,176,870. Can you guess what comes next? If you're stumped, you're not alone. These are the first five busy beaver numbers. They form a sequence that's intimately tied to one of the most notoriously difficult questions in theoretical computer science. Determining the values of busy beaver numbers is a daunting challenge that has attracted a cult following among both professional and amateur mathematicians for over 60 years.

The excitement was palpable at their pop-up merch store at St Stephen's Green, Dublin, as fans eagerly awaited the band's upcoming performances at Croke Park.
