Gravity used to be the most dependable rule in the cosmic rulebook, the quiet background force that never changed its mind. Now a series of discoveries and bold claims are turning that certainty into ...

Science journalist Nadis and Tsinghua University mathematician Yau follow up 2019’s The Shape of a Life with an esoteric exploration of geometry’s role in explaining gravity and the structure of the ...

The mystery of dark matter—unseen, pervasive, and essential in standard cosmology—has loomed over physics for decades. In new research, I explore a different possibility: Rather than postulating new ...

Legend has it that Isaac Newton had the moment of inspiration that would lead to his theory of gravity when, on a warm ...

What would happen to the solar system if half of the universe disappeared? From Newton to Einstein, most experts have agreed that nothing much would happen except that the sky would have fewer stars.

The gravity quantum field is calculated in flat spacetime. The curved classical metric is calculated using the expectation value of the gravity quantum field. At long last, a unified theory combining ...
