A bold claim that the universe’s accelerating expansion was an illusion has been put to the test—and failed. Researchers ...

Physicists may soon witness a cosmic fireworks show: the explosive death of a primordial black hole. Once thought to be unimaginably rare, new research suggests there’s up to a 90% chance of catching ...

Astronomers may have discovered one of the clearest examples yet of a rare "pair-instability" supernova. It is a catastrophic ...

Physicists have long believed that black holes explode at the end of their lives, and that such explosions happen—at most—only once every 100,000 years. But new research published in Physical Review ...

Physicists think we could see such an explosion in the next 10 years - and it would 'revolutionize physics and rewrite the history of the universe'. This artist’s concept takes a fanciful approach to ...

This artist's concept takes a fanciful approach to imagining small primordial black holes. In reality, such tiny black holes would have a difficult time forming the accretion disks that make them ...
