A team of scientists is proposing a bold alternative to the Big Bang theory, suggesting that our universe may have formed ...

What we saw in the DESI experiments, and now strengthened by our South Pole Telescope observations, is that dark energy is ...

A controversial theory suggests the observable universe is the result of matter rebounding after the collapse of a black hole ...

Gravitational wave telescopes have revealed a long-predicted, new class of black hole Black holes observed in the universe were either relatively small, or extremely massive — until now ...

"Critical phenomena in gravitational collapse, close to the onset of black-hole formation, were first reported by Matt Choptuik about 30 years ago," Thomas W. Baumgarte, co-author of the paper ...

By simulating the gravitational wave signals that might be emitted during a warp drive collapse, Clough and her team propose a method for potentially identifying such events—should they exist.

The leading theory of planetary formation, called core accretion, occurs when grains of dust in the disk collect and grow to form a planetary core, like a snowball rolling downhill. Once it has a ...

Gravitational waves are tiny ripples in the fabric of time and space that are created by some of the universe's most powerful events such as colliding black holes.

There are two dominant models of how stars form. Under gravitational collapse, star-forming molecular clumps, of typically hundreds to thousands of solar masses (M ⊙), fragment into gaseous ...
