MIT physicists froze a mirror using lasers in a daring bid to catch gravity behaving like a quantum force — and it just might ...

Now, the work-energy principle says that in order to change the energy of a system, you need to add energy to (or remove ...

If it’s true, this work could have ramifications for some of the biggest mysteries of the universe, including learning where ...

One of the most profound open questions in modern physics is: "Is gravity quantum?" The other fundamental ...

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 ...

It tends to move the object towards the mass. The strength of this force depends on the gravitational constant. Denoted by a ‘G’, it is a fundamental physical constant. It was first accurately ...

In June, researchers from the North American Nanohertz Observatory for Gravitational Waves, or NANOGrav, published the results of 15 years of observations, finding evidence for a constant, ...

There was a secret inside the envelope in the hands of Stephan Schlamminger, one of the world’s leading experts in experimental tests of gravity. He appeared to be on the verge of opening the ...

2: They use changes to the cosmic microwave background (CMB) – radiation leftover from the Big Bang event – to estimate the Hubble constant. 3: They use gravitational waves, ripples in ...
