AI's failed attempt to crack the Riemann hypothesis still led to a breakthrough
An attempt by Anthropic's Claude failed to prove the Riemann hypothesis, but it did produce something genuinely useful: inspiration.

Gravity Seems Holographic. What Does That Mean for Reality? | Quanta Magazine
The biggest breakthrough in modern theoretical physics is the discovery that gravity can collapse the dimensions of space. Physicists don’t yet understand the implications.

To see how huge TON 618 is, consider how *small* its surface gravity is. This is the force per unit test mass registered by a stationary observer at infinity holding the mass static right above the horizon via a long string. Weirdly, it's *small* for *big* black holes.

Its engine is one of the most massive black holes known.

Wow: enormous slabs of colder, denser rock slowly sink through the upper mantle until they hit the lower mantle 660 kilometers down! They're 30-100 km thick and up to a thousand km across.
Then they flatten out, piling up until they break through in million-year avalanches.
It's a very slow drama.

Suposo que arriba un moment on els que manen es creuen que res pot afectar al sistema que els fa manar i que poden fer el que vulguin. I potser funciona algun temps.
Presumably there are historical cases of civilizations going into decline due to unavoidable exogenous factors, but I have a new appreciation for the role played by the civilization itself just turning its back on everything that made it succeed.
