Please join my mailing list here 👉 https://briankeating.com/list to win a meteorite 💥 Is hype culture killing science?  In this episode of Into the Impossible, I welcome back physicist Lawrence Krauss for a candid conversation on hype, being wrong, and the impact of AI on the field of physics. Krauss is a theoretical physicist, award-winning NYT bestselling author, and host of The Origins Podcast. He shares how data forced him to change his mind on dark energy and the Higgs boson, and why science’s strength lies in its willingness to adapt. We explore the hype around quantum gravity, the limits of knowledge revealed by Gödel’s incompleteness theorems, and whether AI can ever truly discover new laws of physics. From black holes to the fate of cosmic intelligence, Krauss takes us to the edge of what we know, and beyond. Key Takeaways: 00:00 Intro  01:22 The energy of empty space 03:13 The recent DESI results 04:16 Quantum gravity as a theory of everything 11:07 The sunk cost fallacy  13:48 The impact of AI on physics  18:00 Advice to his younger self Additional resources:  📚 The War On Science by Lawrence Krauss: https://a.co/d/6ntEbll  ➡️ My new book: 📖 Into the Impossible Volume 2: Focus Like a Nobel Prize Winner: Lessons from Laureates to Concentrate Your Creativity and Ignite Your Career: ⁠⁠https://a.co/d/hi50U9U⁠⁠  ➡️ Follow me on your fav platforms: ✖️ Twitter:⁠⁠ ⁠⁠⁠⁠https://twitter.com/DrBrianKeating⁠⁠  🔔 YouTube:⁠⁠ https://www.youtube.com/DrBrianKeating?sub_confirmation=1⁠⁠  📝 Join my mailing list:⁠⁠ ⁠⁠⁠⁠https://briankeating.com/list⁠⁠  ✍️ Check out my blog:⁠⁠ ⁠⁠⁠⁠https://briankeating.com/cosmic-musings/⁠⁠  🎙️ Follow my podcast:⁠⁠ ⁠⁠⁠⁠https://briankeating.com/podcast⁠⁠  — Into the Impossible with Brian Keating is a podcast dedicated to all those who want to explore the universe within and beyond the known.

I always object to hype in science because it always comes back and bites you in the butt.

When scientists claim things that aren't the case, they're laid to be proved wrong. The hype about quantum gravity being a theory of everything, even if it were true, it's probably a theory of very little. Namely, it's a theory of the beginning of the universe in the center of black holes, but you don't have to know anything about quantum gravity to figure out how old me boils or to build your detectors for that matter. After the first time you were on the podcast, we've known each other for 32 years.

Really? Well, you were just a little, I was a wee lad. Just a little bit of noise in my life back that. That was quite noisy. By the way, do you know where the word, since you're an erudite Renaissance man, do you know where the word noise comes from, what its etymology is? Of noise? Yes.

1:09.4

No, I know some languages, but I know in French it's probably, so it doesn't come from that.

1:13.7

It's not going to lay. It isn't from Latin. It is from Latin. It's related to the root word nausea. It's related to the root word nausea. So now you know what we feel when we experimentalist encounter noise and what you felt when you first met me. me. Okay, Lance, here we go. This was a comment that I got after your first appearance.

1:29.8

It's been more than nausea. Go on. You write very beautifully, as usual. I enjoy reading your books, even when they depress me and caused me to go to the Prozac, Xanax, and Viagribin, all at the same time, Lawrence. But you write beautifully. You say, science works because it changes its mind.
