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 ...

Primordial black holes are hypothetical black holes thought to have formed moments after the Big Bang. Because they supposedly formed about 14 billion years ago, and black holes are thought to ...

New research suggests that there is a 90% chance that within the next decade, humanity could use a space or Earth-based ...

A tiny particle that smashed into Earth with a record-shattering energy of 220 petaelectronvolts could be the last scream of ...

The team explores one of the greatest discoveries of modern astronomy - that our universe is expanding - and the new ...

Some things we see in space appear to outpace light. Now we are learning to harness these bizarre optical illusions to ...

A backward, mirror universe could explain the existence of dark matter. If an anti-universe exists, it would run backward in time, before the Big Bang. Dark matter, then, could be right-handed ...

The low carbon levels are particularly interesting, as previously discovered “pristine” or metal-poor stars generally ...

About a century ago, scientists were struggling to reconcile what seemed a contradiction in Albert Einstein’s theory of general relativity. Published in 1915, and already widely accepted worldwide by ...

The John N. Bahcall Lecture Series Presenter: Robert Kirshner, Clowes Professor of Science, Harvard University Exploding stars halfway across the universe show that the expansion of the universe is ...

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 ...
