・Einstein’s theory of gravity may behave slightly differently across distances of billions of light-years, with gravity appearing about 1 percent weaker on cosmic scales. ・The proposed “cosmic glitch” ...

Researchers at Columbia University have found that, under the right conditions, gravitational fields can break and reconnect, ...

The mass of distant galaxies cannot be determined by the brightness of their stars alone. The speed at which gas moves within ...

A group of researchers at the University of Waterloo and the University of British Columbia have discovered a potential "cosmic glitch" in the universe's gravity, explaining its strange behavior on a ...

A recent study has investigated teleparallel gravity and its potential to resolve tension surrounding the expansion of the universe in a way that general relativity can't. In the early 20th century, ...

Legend has it that Isaac Newton had the moment of inspiration that would lead to his theory of gravity when, on a warm afternoon, he saw an apple fall from a tree and wondered why it should fall down ...
