For centuries, humanity has gazed at the stars, unraveling the mysteries of celestial motion. But what if the unusual orbits ...

Recent studies suggest quantum mechanics supports cosmic censorship, reinforcing black holes' role in hiding singularities.

Einstein's theory of general relativity describes the inevitability of singularities, which are obscured by black holes ...

The known black holes that populate the universe fall into two types: those up to a few dozen times the mass of the sun and ...

Physical phenomena in astrophysics and cosmology involve gravitational collapse in a fundamental way. The final fate of a massive star when it collapses under its own gravity at the end of its life ...

If the neutrino burst from the CCSN is not isotropic, it will generate additional gravitational radiation from that of the collapse. Sourced by previously emitted waves, these "bursts with memory ...

If the modern age of astronomy could be summarized in a few words, it would probably be "the age of shifting paradigms." ...

critical phenomena in gravitational collapse, the initial value problem of general relativity, and relativistic astrophysics. Research in gravitational physics is currently being conducted in JILA.

The most detailed map of the universe ever created using gravitational waves could reveal hidden black holes, merging supermassive black holes and even the large-scale structure of the cosmos.

Lots of things out in the universe can cause a supernova, from the gravitational collapse of a massive star, to the collision of white dwarfs. But most of the supernovae we observe are in other ...

Most of the neutron stars we know of have a mass between 1.4 and 2.0 Suns. The upper limit makes sense, since, beyond about ...
