Confirming a pulsar star would enable unprecedented tests of General Relativity. Such a discovery would revolutionize physics ...

A record-breaking gravitational wave signal let scientists "listen" to a distant black hole merger and put Einstein's gravity to its toughest test yet.

For over a century, scientists have been intrigued to decode the perplexing scenery behind contemporary physics. It's been up for many years, and yet the experts still have no idea how to bridge the ...

The puzzle Einstein and Rosen were addressing was never about space travel, but about how quantum fields behave in curved spacetime. I ...

So far, the most accurate model describing gravity is still Einstein’s theory of general relativity. It states that gravity as we feel and observe it is a kind of side effect of the fabric of ...

The second reason is simple: location, location, location! The millisecond pulsar appears to be near Sagittarius A*, the ...

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 ...

Quantum Gravity and General Relativity represent two foundational yet traditionally disparate pillars of modern physics. General Relativity, Einstein’s seminal theory, elegantly encapsulates ...

What exactly is … everything? What is space-time? At one extreme, you’ve got the weird rules of quantum physics that deal with subatomic particles. At the other extreme, you’ve got the vast expanses ...
