When the theoretical physicist Leonard Susskind encountered a head-scratching paradox about black holes, he turned to an unexpected place: computer science. In nature, most self-contained systems eventually reach thermodynamic equilibrium… but not black holes. The interior volume of a black hole appears to forever expand without limit. But why? Susskind had a suspicion that a concept called computational complexity, which underpins everything from cryptography to quantum computing to the blockchain and AI, might provide an explanation.

He and his colleagues believe that the complexity of quantum entanglement continues to evolve inside a black hole long past the point of what’s called “heat death.” Now Susskind and his collaborator, Adam Brown, have used this insight to propose a new law of physics: the second law of quantum complexity, a quantum analogue of the second law of thermodynamics.

The famous red giant has behaved oddly in recent years and astronomers now believe the end is close.

Puzzling ancient galaxies and oddly shaped clusters suggest we have glimpsed cosmic strings travelling at the speed of light – and with them clues to a deeper theory of reality.

By Dan Falk

Recent Gaia satellite findings suggest that dwarf galaxies are transient and less influenced by dark matter than previously believed, challenging long-held assumptions about their nature and composition.

Commonly thought to be long-lived satellites of our galaxy, a new study now finds indications that most dwarf galaxies might in fact be destroyed soon after their entry into the Galactic halo. Thanks to the latest catalog from ESA’s Gaia satellite, an international team has now demonstrated that dwarf galaxies might be out of equilibrium. The study opens important questions on the standard cosmological model, particularly on the prevalence of dark matter in our nearest environment.
