What's New in Science With Sabine and Lawrence

I’m excited to announce the fourth episode of our new series, What’s New in Science, co-hosted by Sabine Hossenfelder. Once again, Sabine and I each brought a few recent science stories to the table, and we took turns introducing them before diving into thoughtful discussions. It’s a format that continues to spark engaging exchanges, and based on the feedback we’ve received, it’s resonating well with listeners. It was a bit of a slow month for science news, but we did find six stories worth examining, including what sounds like a preposterous claim, turning rain into electricity! It turns out it doesn’t violate any laws of physics, but is not likely to address our energy needs. The Hype of the Month award goes to the claim of biosignatures on planet K2-18, which got worldwide coverage, even though experts were pretty certain it was wrong from the get go, and subsequent analysis finds no such evidence. A claim that gravity is just a computation is examined, and dismissed, while evidence for exotic antimatter nuclei at CERN is sound science, even if it is not earth shattering. It reminds us that exotic physics must be considered in exotic locations like the early big bang, or the cores of neutron stars. Sabine was excited about a new result regarding laser fusion, even if it is more likely to be useful for weapons production than commercial energy production, and this time, I was the one to bring up a new result in Quantum Computing, this time using ‘qu-quints’ to simulate an actual physics system, although a simple one in two dimensions. It was another lively and thoughtful exchange, and I hope you’ll enjoy it as much as we did. As always, an ad-free video version of this podcast is also available to paid Critical Mass subscribers.
