Black holes are often described as cosmic traps from which nothing can escape, yet modern physics says they are not perfectly black. At their edges, quantum effects make them glow with a faint thermal ...

Astronomers using the Event Horizon Telescope -- a planet-scale array of eight ground-based radio telescopes -- have ...

A newly detected gravitational wave, GW250114, is giving scientists their clearest look yet at a black hole collision—and a powerful way to test Einstein’s theory of gravity. Its clarity allowed ...

On January 14, 2025, the Laser Interferometer Gravitational-wave Observatories (LIGOs) recorded a cosmic tremor unlike any before. Named GW250114, the signal was the ‘loudest’ gravitational wave ...

For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational wave signal from a binary black hole merger to date, and it gives researchers ...

A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the universe would fall apart if it all remained unchanged. This theory tries to ...

For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational wave signal from a binary black hole merger to date, and it gives researchers ...

As internet conspiracy theories go, this one was exceptionally dumb. At the turn of the century, it sounded as if string theory could give us big answers about the universe. Well… has it? A ...
