How confusing inevitability with reality built decades of paradox. What if general relativity never actually tells us that ...

Black holes, regions of immense gravity preventing light escape, were theoretically predicted by Einstein's general relativity and confirmed through observations of intense X-ray sources like Cygnus X ...

A comprehensive set of simulations by Flatiron Institute astrophysicists and their colleagues revealed that magnetic fields are responsible for creating black holes with masses in a range previously ...

Scientists may have "heard" the first tantalizing evidence of primordial black holes formed directly from overly dense ...

A new paper explores the idea of asteroid-sized objects that may be causing gravitational ripples in our cosmic neighborhood. Reading time 2 minutes Black holes are some of the most vexing objects in ...

The deepest mysteries of the universe often begin with the biggest questions. Few are more puzzling than the birth of supermassive black holes. These giants, weighing millions to billions of times ...

Black holes, like the one in this illustration, can spray powerful jets. S. Dagnello (NRAO/AUI/NSF), CC BY-SA One of the most powerful objects in the universe is a radio quasar – a spinning black hole ...

If a new proposal by physicists bears out, the recent detection of a record-setting neutrino could be the first evidence of elusive Hawking radiation. (Nanowerk News) The last gasp of a primordial ...

One of the most notable aspects about our planet—if observed from the outside—is that it spins. Earth’s spin defines our days, setting the fundamental rhythm of life on our world. The moon spins, too.

An undiscovered population of ancient black holes may be lurking throughout the universe. These bottomless cosmic pits would have a lot in common with more familiar black holes; in some cases, the two ...
