The talk is free but registration is required: simonsfoundation.org/event/the-blac… In the meantime, you can find out more about the Black Hole Explorer mission here: blackholeexplorer.org

Interested in the future of black hole imaging? I will be giving a public talk in NYC next week on Wednesday (3/18) about "The Black Hole Explorer: Tracing an Edge of the Visible Universe". This is part of the Simons Presidential Lecture series hosted by the Simons Foundation.

It is blurring the line between tool and collaborator economist.com/science-and-te…

@SebastienBubeck That is one pretty unicorn

@marikgoldstein Thank you for your interest! My upcoming public talk at the Simons Foundation (simonsfoundation.org/event/the-blac…) will be focused on the future of space-based black hole imaging with the Black Hole Explorer (blackholeexplorer.org)

@ALupsasca I thought the takeaway is also about the graviton! looking forward to hearing about it if you discuss at your flatiron talk

We just posted a new preprint: “Single-minus graviton tree amplitudes are nonzero.” Yes: a helicity sector long assumed to vanish in quantum gravity can actually appear under well-defined kinematics. Preprint: cdn.openai.com/graviton/gravi…

@bigwersk @grok I should have also shared this blog post with an explanation in layman's terms: openai.com/index/extendin…

@ALupsasca @grok can you explain to me this thread in layman's terms please?

💥 AI accelerating high energy physics Just a few weeks after the gluon scattering paper, this morning we posted the more complicated graviton scattering analogue. See below for more from @ALupsasca 👇

Takeaway: this is strong evidence that AI can push the frontier of theoretical physics—and, even more importantly, that it compresses the discovery cycle by shifting effort toward checking and exposition! Lots more to come; feedback welcome in the meantime!

We’re sharing the receipts: a long chat transcript of the initial exchange that generated the core ideas and an early draft. Transcript: cdn.openai.com/graviton/gluon….

@dlouapre Thank you David for an excellent summary!

Link to the blog post where I will walk you through Yang-Mills theory, Feynman diagrams, perturbative expansion and single minus gluon scattering amplitudes ! huggingface.co/blog/dlouapre/…

OpenAI claims GPT-5.2 made a breakthrough in theoretical physics. Reactions ranged from "physics will never be the same" to "it's just a calculator" As a former theoretical physicist, I tried to understand what actually happened, and the physics relevance of the discovery⬇⬇

@doctor__romeo Thanks Romeo!!!

@ALupsasca Congratulations! 🎊

I have to postpone my public talk at Harvard today. My wife is about to give birth and I’m headed to the hospital! Hope to be back soon

@nasqret Hi Bartosz, in this case the physical question essentially reduces to a problem that is combinatorial in spirit, so yes there is a lot of interesting overlap!

Thanks Alex for this post. It is very interesting in comparison to see that some aspect of theoretical physics can be attacked by the same methodology as problems in computational algebra and number theory. There must be some deeper reasons related to AI training and the usability of LLMs that allow such techniques to work. Fascinating example.

Our recent preprint on gluon amplitudes has sparked a lot of discussion, so I want to share the backstory — including how AI helped crack a problem that had stumped us for a year. I'll also be giving a public lecture at Harvard this week. Details at the end.

@skominers Hahaha that's the spirit, Scott!

@fjrojasf Thank you, Francisco! GPT-5.2 Pro is publicly available. The scaffolded version that I used internally is not, but I expect that its capabilities will get into the public model before long.

@ALupsasca This is awesome. Thank you for the post Alex! By the way, is the ChatGPT version you guys used already available for everyone? If not, will it be available soon?
