Quantum Gravity
A team of researchers has tested Einstein's century-old principle that the speed of light remains constant, using observations of distant gamma rays. Their analysis found no violations of this rule but improved existing constraints by an order of magnitude. The study highlights ongoing efforts to reconcile quantum theory with gravity.

A new mathematical model suggests that quantum entanglement between black holes can create bumpy space-time tunnels resembling caterpillars. Researchers at Brandeis University have found that these wormholes are typically lumpy rather than smooth, differing from earlier theories. This work aims to shed light on the mysterious interiors of black holes.
