A fresh black hole merger detection has offered the clearest evidence yet for Einstein’s relativity and Hawking’s predictions ...

Believe it or not, the quantum vacuum... isn't completely empty. It has tiny vibrations or “sparks” of energy. If an object ...

Alexander Grothendieck was a titan in his field, making deep connections that fuelled a revolution in mathematics, before ...

A fresh black hole merger detection has offered the clearest evidence yet for Einstein’s relativity and Hawking’s predictions. Scientists tracked the complete cosmic collision, confirming that black ...

The true “informational age” of the cosmos may be 62 billion years, not just the 13.8 billion years of our current expansion.

New observations of two black holes merging have confirmed predictions made decades ago by Albert Einstein, Stephen Hawking, ...

Black holes are so strange that physicists have long wondered if they are quite what they seem. Now we are set to find out if ...

Einstein’s uncle Jakob was an inventor in Munich. He produced patents for arc lamps, electric meters, and dynamos in the late ...

Black hole merger detected by LIGO offers the strongest proof yet of Einstein’s relativity and Hawking’s predictions. The findings confirm black holes are defined by spin and mass. Their event ...

Whether space-time exists should neither be controversial nor even conceptually challenging, given the definitions of “space-time,” “events” and “instants.” The id ...

Space-time is the map of where and when events happen. A worldline is the record of every event that occurs throughout one’s life. The key question is whether the map — or all the events it draws ...

Supermassive black holes, the hungry hungry hippos of the universe, aren’t actually that supermassive, apparently. Black ...
