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 ...

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

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 ...

These hypothetical black holes are believed to have formed soon after the Big Bang, resulting from pockets of subatomic ...

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.

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 ...

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 ...
