Scientists first detected ripples in space known as gravitational waves from the merger of two black holes in September 2015.

"GW250114 is the loudest gravitational wave event we have detected to date; it was like a whisper becoming a shout." ...

Ripples in spacetime sent hurtling through the universe when two black holes smash into each other -- a phenomenon predicted by Albert Einstein -- have confirmed a theory proposed by fellow physicist ...

First, gravitational waves proved Einstein correct. Now, they’ve confirmed Stephen Hawking was right about black holes.

Gravity is a ubiquitous part of our daily lives — whether we’re being tragically brought to our knees after tripping on the rug or gleefully jumping from a swing’s apex. But despite how common the ...

In 2010, renowned string theory expert Erik Verlinde from the University of Amsterdam and the Delta Institute for Theoretical Physics proposed that gravity is not a fundamental force of nature, but ...

The weak gravitational pull on a particle just half the mass of a grain of sand has been measured for the first time. This most precise measurement of its kind is a breakthrough towards the quantum ...

Many theories are rock-solid: Scientists have just as much confidence in the theories of relativity, quantum mechanics, ...
