Could cosmic memory explain dark matter, dark energy, and black holes?
For more than a century, physics has been built on two great theories. Einstein’s general relativity explains gravity as the bending of space and time.
Quantum mechanics governs the world of particles and fields. Both work brilliantly in their own domains. But put them together and contradictions appear – especially when it comes to black holes, dark matter, dark energy and the origins of the cosmos.

Pigeons are always looking ahead yod67/Alamy
Scientists have tracked the eye movements of a bird in flight for the first time, revealing that pigeons in the air lock their eyes in place rather than looking around. The behaviour may help them control their flight, but it could also leave them more vulnerable to predators.
Superconductivity breakthrough could unlock ultra-efficient electronics
Superconductors could one day help power a new generation of ultra-efficient electronics, but major technical hurdles have kept the technology largely confined to research labs. Now, scientists at Chalmers University of Technology in Sweden have developed a new approach that tackles one of the field's biggest challenges: maintaining superconductivity at higher temperatures while also resisting strong magnetic fields.
