Show HN: Throw Alice and Bob into Sagittarius A* https://ift.tt/e8OGIzu

Show HN: Throw Alice and Bob into Sagittarius A* Black Hole Lab is an open source physics simulation of a rotating black hole and two observers, Alice and Bob. You can launch Alice and Bob on paths around or into the black hole and watch events play out. The simulation lets you see a slice of the physics with one or two dimensions of space plus one of time. As a fun extra, Alice and Bob each have a beacon that can transmit a radio wave in all directions. The simulation calculates and shows the wavefront of these signals, accounting for the warping of space and time by the black hole. The simulation also records whenever Alice and Bob receive each other's transmission. The simulation takes pains to respect Einstein's equations of general relativity. To the precision of the numerical integration, the effects shown in Black Hole Lab are really what the math of general relativity says will happen. Black Hole Lab specifically uses the Kerr metric, which is an exact solution to Einstein's equations of general relativity for a rotating mass. That said, physicists agree that general relativity cannot be the final word on black hole physics. Nobody can say what would really happen to Alice and Bob. My original goal for black hole lab was to try to understand the strange time compression effects at the inner horizon, which physicists call infinite blueshift. IMHO, Black Hole Lab succeeds in showing this effect in an understandable way. I added a specific discussion of infinite blueshift in the readme. https://ift.tt/9VyfaBO October 11, 2026 at 02:58AM

Show HN: A functioning Celery Man computer Hi HN! It dawned on me that the latest AI models (Minimax H3 Max / Audio, GPT-6 Luna) can finally recreate the computer from the classic Tim & Eric Celery Man sketch. I spent a few days creating it: it has 100% parity with the original script, plus anything you ask for (doggy woof woof man or potato boy). Happy to answer any questions about the pipeline! https://celeryman.fun/ October 10, 2026 at 11:38PM

Latine Heritage Month Spotlight: Supporting Spanish-Speaking Communities

Latine Heritage Month Spotlight: Supporting Spanish-Speaking Communities
By Glennis Markison-Busi

Beatriz Flórez Huertas shares information about SFMTA programs. This Latine Heritage Month, we are celebrating the work of SFMTA Community Liaison Beatriz Flórez Huertas. At the heart of her job: helping Spanish-speaking communities get around San Francisco. And Flórez Huertas is especially sensitive to what newcomers might be facing. Starting with empathy When Flórez Huertas came to the U.S., she had no connections. She had to learn how to navigate transit, find housing and build a career all on her own. “When you don’t have family here, who do you rely on?” Flórez Huertas had to ask. “Who...
