Recently, I watched an interview of Raphael Bousso by Brian Greene, it was mostly on the black hole information paradox and aspects of the singularity theorems. In the end Brian Greene mentioned something regarding the usage of LLMs in physics research.
Brian and a few of his collaborators wrote a paper on orientable manifolds over a few months. Brian could nudge ChatGPT and guide it as a grad student to discover the same result in less than half an hour with only vague hints — completely written paper and all!

Most people don’t know, but this is also called the Landau–Raychaudhuri equation. I’m currently down a rabbit hole why is it called that? Let me know if you know 😅

Do you know ?? Ashoke Sen, the renowned String Theorist of India who produced Sen Conjecture & S-Duality is a student of Amal Raychaudhuri !! Raychaudhuri produced the Raychaudhuri equation. The Raychaudhuri Equation is often taught as a GR tool. But that’s like calling calculus “a physics trick.” Because Raychaudhuri’s equation is deeper than gravity: it’s a geometric statement about congruences and flows.

@gopal_lohar_0 @shreyadoesstuff You're right, it's 10⁸⁰ or something, see this is why I don't do good with these big numbers.

@star_stufff @shreyadoesstuff Nope, it's like equal to number of atoms in a bacterium.

sorry..... HOW MUCH?!!???!??!?!!?!??!??

JUST IN: Meta announces they'll be shutting down the Metaverse, after pouring $80,000,000,000.00 into the project.

Here's a bright fucking idea: maybe if we didn't spend hundreds of billions of dollars on waging endless wars, physics would progress far faster?

I think I found that one paper that will help me finish the last section of my paper on *an* electromagnetized (a test field here) Kerr BH.

Einstein did a simple thought experiment applying the equivalence principle to light in which he clearly demonstrated that the path of a light beam in an accelerated gravitational frame will be curved (this is demonstrated very nicely in Susskind's GR book). But after that came the hard part - figuring out the math that would describe this phenomenon. It took Marcel Grossmann's help with Riemannian geometry and tensors and Einstein's uncanny feel for invariants and general covariance that helped him achieve the end results after several painstaking attempts and dead ends.

@curiouswavefn Agreed. There was enough unexplained data to drive physics to SR. But not so GR. It was Einstein's decision to try to apply the principles he used in SR to broader cases that led to GR.

Extremely rare footage of David Hilbert and Hermann Weyl. Randomly popped on my YouTube feed.

@DeivonDrago FFS can a hep-th bro win ONE FUQQING TIME JUST ONCE?!?!?!?!?!?!?!?!

Absolutely, maybe we would have discovered it very late when particle physics was emerging. People like Feynman would have certainly described gravitational interaction in terms of graviton exchange. The geometric description really required someone like him with that solid imagination. The key was the equivalence principle throughout!

Dirac once said that special relativity would have been discovered very soon if Einstein had not done so, but general relativity would have taken a very long time (although Hilbert came close - he got much of the math right but lacked Einstein's profound physical intuition and thought experiments).

Einstein submitted his paper “The Foundations of the General Theory of Relativity” to Annalen der Physik this week in 1916. It collected his work from throughout 1915, presenting the broader scientific community with a complete and coherent account of general relativity.
