For the first time, physicists have watched a beam of positronium, a short‑lived atom made of an electron and its antimatter twin, behave like a rippling quantum wave instead of a stream of tiny ...

An unusual gravitational wave signal has renewed hopes that primordial black holes, long considered purely theoretical, may ...

Black holes could reveal the presence of dark matter in their immediate vicinity through their gravitational waves. Gravitational waves, predicted by Einstein, are ripples in spacetime. They travel at ...

Gravitational waves could be responsible for the production of dark matter during the early phases of our universe's formation, according to results of a new study by Professor Joachim Kopp from ...
