Please join my mailing list here ๐Ÿ‘‰ https://briankeating.com/list to win a meteorite ๐Ÿ’ฅ A few weeks ago, I released a video about whether string theoryโ€™s biggest competitor, Loop Quantum Gravity, might have suffered a fatal blow. Catch it here https://youtu.be/krifXJLTfQk The video sparked a lively debate across YouTube, with creators like Sabine Hossenfelder and Phil Halpern making reaction videos and Carlo Rovelli even reaching out to me personally, asking me to take it down. Now, I want to clarify the situation and share my perspective on whether Loop Quantum Gravity is truly on its last legsโ€”or if thereโ€™s more to the story. Tune in to the Loop Quantum Gravity War! Key Takeaways: 00:00 Intro 00:46 My initial video on loop quantum gravity 03:25 Quick recap of my correspondence with Carlo Rovelli 04:20 The problem with string theory and loop quantum gravity 09:08 Reacting to Sabineโ€™s video 12:55 My final thoughts Additional resources: โžก๏ธ Check out the videos referenced: ๐Ÿ”” Sabineโ€™s video: https://www.youtube.com/watch?v=ZlHvW6k2bcM ๐ŸŽ™๏ธ Philโ€™s video: https://www.youtube.com/watch?v=S5CzrLuCRS4 โžก๏ธ Follow me on your fav platforms: โœ–๏ธ Twitter: https://twitter.com/DrBrianKeating ๐Ÿ”” YouTube: https://www.youtube.com/DrBrianKeating?sub_confirmation=1 ๐Ÿ“ Join my mailing list: https://briankeating.com/list โœ๏ธ Check out my blog: https://briankeating.com/cosmic-musings/ ๐ŸŽ™๏ธ Follow my podcast: https://briankeating.com/podcast โ€” Into the Impossible with Brian Keating is a podcast dedicated to all those who want to explore the universe within and beyond the known.

Sabine just dropped a blistering diss track

People should stop being offended. If someone said your theory sucks, it's up to you either to prove it does not suck or ignore him. But being emotionally offended is not an option.

As a Brit I would like to contribute some of my own expertise : "bollocks" are spherical objects usually seen in pairs that orbit one another in a kind of nebula-like sac that is gravitationally locked to the pillar of creation.

Sabine just published a video and brought the dilemma of modern physics to the point. I can just repeat what I wrote in her channel: I work with a couple of highly educated, PhD. holding physicists together at Siemens. They all complain about the situation you explain here and they are all pointing to the root cause: It's about the money. People construct fancy theories to pretent progress. Why would else one give them money? It starts at the universities. Modern physics is dead and that will remain till the system gets changed.

I have a theory it is called "gravity loop quantum string field" to satisfy both parties.

After watching Sabineโ€™s last and the latest video, I feel whoever disagree with her should try to point out the flaw in her argument, if there is any. As someone who studied a bit physics during undergrad, i feel her argument is pretty clean and conclusive.

I'm not a physicist, but an applied mathematician, which should make my bias obvious. Remember going to lots of talks on this topic during my PhD and postdoc. Even back then, I always thought how on earth all these labs pull in funding without even having a plan for verifiable results. My personal opinion is that creating new math is like creating art. It can be beautiful and elegant, and has value. But with limited funding, I'd rather see resources being put towards more practical endeavours.

What is the best candidate for a Theory of Quantum Gravity: String Theory or Loop Quantum Gravity? Or something else?
