Unproven Einstein theory of 'gravitational memory' may be real after all, new study hintsEinstein's theory of general relativity suggests that the "memory" of ancient events, such as black hole mergers, may be etched into the fabric of space-time by gravitational waves. New research shows how this theory of gravitational memory could finally be proven.

'Einstein's equations need to be refined': Tweaks to general relativity could finally explain what lies at the heart of a black holeBlack hole singularities should not exist, according to theories of quantum mechanics. New tweaks to Einstein's equations of general relativity could finally do away with them, and explain what truly lies at the heart of a black hole.

'Impossible' black holes detected by James Webb telescope may finally have an explanation — if this ultra-rare form of matter existsObservations from the James Webb Space Telescope reveal monster black holes in the early universe that seem to have grown too big, too fast. New research points to a strange form of dark matter as a possible culprit.

Antimatter detected on International Space Station could reveal new physicsEight years ago, the International Space Station detected weird antimatter particles that challenge our entire understanding of physics. Now, researchers have proposed that mysterious cosmic "fireballs" could help explain the detection.
