Must there be a single unified theory of physics?

Daniel and Kelly talk to Ethan Siegal (Ethan Siegel ) about whether we should expect physics to be explained by a single unified theory. iheart.com/podcast/105-da…

Today’s episode is exactly the kind I love: two experts in their fields debating the best way to uncover the universe's mysteries. Lately, I’ve been dabbling in poetry, and after listening to today’s episode, I felt inspired. The Physicist’s Waltz One counts the known, one

Can we make mental contact with aliens using our most universal science, physics? What if our physics is more human than we expect, alien science more alien? This is the topic of my book, "Do Aliens Speak Physics?" out next week! Here's what Seamus Blackley said about it:

Would aliens describe the Universe the same way we do? Many physicists think "obviously, yes!", but that confidence is built on lots of untested assumptions. My book, "Do Aliens Speak Physics?" unpacks the assumptions with a lot of dad jokes. Here's what Sean Carroll said:

Lovely listener email: "I love you both, even when your jokes are a bit corny, I suppose those a moments I realise I'm listening to nerds, but I'm a nerd too so that's not a criticism etc...you make me feel that I've been educated by friends. Thank you so much for what you do."
