"Boltzmann Brains" is a fanciful name for a dead-serious idea. I'm beginning to wonder whether the name hasn't caused the physics community to not spend nearly enough time thinking carefully about the problems that they pose. We have Boltzmann Brain Blindness. Long 🧵 coming. ⚛️ #cosmology (1/n)

Math proofs online, physics research accelerating—as much as could be said about any period in history, this really does feel like a pivotal moment for humanity. I’m just glad to be alive.

I'm sad to report that Mark Wise, theoretical physicist at Caltech, has passed away. He was my friend and collaborator, a giant of theoretical physics, and just one of my favorite people. RIP. www.pma.caltech.edu/people/mark-...

Mindscape 358 | Solo: Vacuum Energy and the Cosmological Constant. I start talking about why the universe is accelerating -- but there was too much to say, so next week we'll have a follow-up episode. #MindscapePodcast www.preposterousuniverse.com/podcast/2026...

An old fable for Dualities in Physics: Once, a group of blind men were asked to describe an elephant. As they reached out to touch it, the one who felt the trunk said it was a snake. Another touched the body and said it was a wall. But in reality, they were all trying to describe the same thing.

Episode 26 with Ashmeet Singh is now the most watched video of the Knowmads podcast. Check it out on YouTube if you missed it. Link in the previous post.

just overheard a 4th grader telling her friend, "if you ever need to distract some boys, literally just draw an X in the dirt. they'll stop to dig it up, they can't help it" which is the only gender metric I'll be using, moving forward

5 things I do as a PhD student so I don’t lose myself. 0/5

The paradoxical nature of our world has led to many discoveries and here’s one that’s still unresolved: The laws of quantum mechanics are perfectly reversible, yet the world we experience is irreversible. 0/7

As I near 5th yr of PhD in Physics, I reflect on lessons beyond eqns, papers & prob-solving. It has taught me patience, humility, resilience & comfort with uncertainty. If you’re considering PhD in fundamental science, I hope this aids honest entry with less fear. 0/5

We have created a world with previously unimagined material abundance, and yet we have organized society such that many people struggle with loneliness and alienation. Now we're offering tools that enhance delusion and paranoia. www.404media.co/delusion-usi...

Full house at @pattersonparkhtx tonight. I had so much fun talking about: Are we living in a Matrix! A big thank you to @after5society for the invite and organising this and a bigger thanks to each and everyone who showed up. Cheers 🥂

Mathematicians call prime numbers the building blocks, analogous to atoms. I find this weird. In physics, building blocks have a smaller scale associated with them, while prime numbers are at the same “scale” as all other numbers. How do you think about this?

This person on Twitter is taking my threads and posts and presenting them verbatim as his own.

Alright, will try to finish this masterpiece this winter.

Can’t wait to share this incredible conversation with y’all.

Recorded a podcast with @danielwhiteson.bsky.social and we talked about his New Book “Do Aliens speak Physics?” (Available November 4th) Stay tuned for a great conversation! @bhavaytyagi.bsky.social

New episode with @evevavagiakis.bsky.social is out now on the Knowmads Podcast @bhavaytyagi.bsky.social m.youtube.com/watch

Recorded a new podcast episode with @nikosarcevic.com Had so much fun and what a scintillating conversation! Can’t wait to share with y’all! @bhavaytyagi.bsky.social

Recorded an episode of The Knowmads Podcast with Eve Vavagiakis @evevavagiakis.bsky.social , Experimental Cosmologist from Duke University. It was one of the most refreshing conversations ever! We (@bhavaytyagi.bsky.social and I) can’t wait to share it with y’all.
