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 century-old thought experiment proposed by Albert Einstein to challenge Niels Bohr's ideas on quantum mechanics has been realized in a real-world test. Researchers led by Chao-Yang Lu at the University of Science and Technology of China used modern tools to confirm Bohr's principle of complementarity. The findings show that light exhibits both wave and particle properties, but not simultaneously in a clear way.
