Spiral galaxies rotate at such a high speed that the gravity calculated only from their visible stars could not prevent them from dispersing. To solve this puzzle, physicists have postulated ...

"It highlights gravity's possible hidden complexity and invites a reevaluation of where dark matter effects originate." ...

A British theoretical physicist has developed a theory that could solve one of the universe’s biggest mysteries: why its rate of expansion is accelerating rather than slowing down, as predicted by the ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. More than 100 years after Albert Einstein first outlined his ideas ...

Gravity used to be the most dependable rule in the cosmic rulebook, the quiet background force that never changed its mind.

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 ...

In a bold step toward solving one of science’s most puzzling problems, researchers have proposed a new way to bring gravity into the same mathematical language as the other forces of nature. While the ...

The image depicts an experiment in which heavy particles(illustrated as the moon), cause an interference pattern (a quantum effect), while also bendingspacetime. The ...

Gravity is one of four fundamental interactions. The most precise description of this force is still provided by Einstein's General Theory of Relativity, published in 1915, an entirely classical ...

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 ...

What if dark matter didn’t exist? Sure, scientists have never observed it, but they believe it exists because of apparent gravitational effects. But what if our current understanding of gravity was ...
