I fed it Carlo's recent papers and asked for the argument, the counterargument, and the evidence that would support or refute each side. Some of the questions and animations in this interview came out of that. It runs the top frontier models in one place, turns a dense PDF into a research report or a presentation with charts, builds interactive dashboards off a spreadsheet, and takes API access if you want it wired into your own tools.

The physicist who built loop quantum gravity says the second law does not say what you were taught it says, and that freedom does not require breaking a single law of nature. Order builds itself. Your head is older than your feet. And neither one is the strangest thing here.
Carlo Rovelli founded the loop quantum gravity program and wrote the relational interpretation of quantum mechanics.
We cover: why oil separating from water is not a violation of entropy, what Galileo got wrong about the one discovery he is most famous for, the paper Einstein published denying gravitational waves, why a chess program that deliberates tells you what your own freedom actually is, and what Rovelli would build with ten years and unlimited money.
“To imagine that to be free you have to violate the laws of nature is stupid.” — Carlo Rovelli

Forecasters gave AI under 2% odds of helping solve a millennium-level math problem by September 2026. It happened. Ethan Mollick has been measuring what AI actually does to real work with field experiments, not forecasts, and his answer is not what most people expect.

Is there alien technology in our skies, or just birds, balloons and bad video?
When two people are vibing, their brainwaves synchronize and so do their heartbeats. That is not a metaphor. It is a measurable physiological event, and organizational psychologist Adam Grant has spent his career figuring out how to make it happen on purpose.

Roman Yampolskiy says keeping a superintelligence safe forever is as impossible as building a perpetual motion machine. Joscha Bach says today's AI is more controllable than anyone expected, and that shutting it down would doom us anyway.
The physicist who turned a cubic kilometer of Antarctic ice into a telescope says the most exciting moment of his career was not the discovery. It was the first atmospheric neutrino. Before that, he was deep in debt to NSF and his own university with no neutrino to show for it.
