It gives a spacetime picture of the complexity roadblock and builds on earlier foundations like Complexity = Action and the Second Law of Quantum Complexity, which treat complexity as a physical resource that tends to grow.

Since then Brown and collaborators introduced Python’s Lunch, a wormhole geometry where a central bulge flags exponentially hard decoding of Hawking radiation.

If recovering the message demands resources that blow up exponentially, the ‘experiment’ may be out of reach in practice.

A few years ago, FQxI funded Adam Brown for Complexity, Black Holes, and Observers. The aim was to show that maybe the real barrier in the black-hole information puzzle is computational, not a breakdown of physics.

FQxI's Leonard Susskind won the the "Galileo Galilei Medal" award. The prize is awarded once every two years to scientists who have massively advanced research in theoretical physics. Congrats Leonard!

Dark matter ≠ dark energy. Dark matter is an unseen mass we infer from gravity; dark energy labels an expansion that seems to speed up. In this clip from FQxI's latest podcast, Niayesh Afshordi talks about why the evidence behind each is different and why the story’s still being told.

*deep sigh* Again, I have an English degree and have contributed rather extensively to the British economy, including writing a show that pumped £10 million into Wales. But the stupidity is the point here, of course.

Badenoch and Co see education only as a means to a massive income in some soul destroying career.

Devoid of imagination and the power of knowledge they view life entirely through the prism of the CV.

My advice always is to study what interests you and the rest will follow

This is a good game.

I have an English degree and boosted a major publishing house’s share price, and saved a high street retail chain from closure.

If a Mickey Mouse degree lets you create actual Mickey fucking Mouse, it’s probably easily as good “for the economy” as business studies.

In swamps and marshes, people occasionally see mysterious blue-tinged flashes of light above water, which have commonly been associated with ghosts or spirits. Now physicists may have finally worked out what causes them.
We may finally know what causes will-o’-the-wisps
Mysterious flashes of light seen in swamps and bogs could be caused by burning methane or other gases, ignited by sparks that fly between bubbles in water

Mike Wright, who since the early 70’s has been recording scientific talks, well before anyone was doing anything like that, resulting in 100,000 hours of recordings.

While a substantial portion is now digitised, some work still needs doing to reach the finishing line.

The Black Spatula project is just starting out, with a community of contributors all exploring different ways that AI might be brought to bear on error checking. "It's still in the experimental phase, with multiple volunteers collaborating to try out different approaches," says Steve Newman.

And the engine idea has moved forward. Antonio Patrón Castro, David Sivak and John Bechhoefer show you can boost output by harvesting perpendicular fluctuations in higher dimensions, even without tracking vertical motion (arXiv:2507.15503).

In "Maximizing power and velocity of an information engine," Bechhoefer’s team showed how a laser-trapped bead can bank energy from random jiggles, acting as an information engine with power on the scale of molecular motors.

Johann du Buisson, Jannik Ehrich, mleighton.bsky.social, davidasivak.bsky.social, and John Bechhoefer introduce a one-coordinate test that infers heat flow to flag “demonic” operation. In kinesin simulations tuned to experiments, the motor grows more demon-like as active fluctuations rise.
