Scientists in Wales have built the world’s most sensitive table-top interferometer, which is a miniature, ultra-precise ...

From Newton’s falling apple to Einstein’s curved spacetime, our understanding of gravity has come a long way, yet this familiar force remains one of the biggest puzzles in physics.

Space power is central to communication, navigation, and surveillance. China’s “Space Silk Road” envisions orbital highways of satellites as critical to global influence, much as maritime routes once ...

What if gravity repelled instead of attracted? This video explores how repulsive gravity could have shaped the history of the ...

Let’s talk about quantum gravity experiments that can be done here on Earth! If we discover how to connect quantum mechanics with general relativity we’ll pretty much win physics. There are multiple ...

When you buy through links on our articles, Future and its syndication partners may earn a commission. An abstract illustration of quantum particles entangling. New research aims to unite gravity with ...

So far, the most accurate model describing gravity is still Einstein’s theory of general relativity. It states that gravity as we feel and observe it is a kind of side effect of the fabric of ...

What if gravity isn’t weirdly quantum at all, but rather … just a bit messy? The holy grail of theoretical physics is to find the long-sought theory of quantum gravity. But what if this theory is as ...

Quantum gravity challenges the classical notion of spacetime by positing that the smooth, continuous fabric described by general relativity may arise from more fundamental, non-spatiotemporal entities ...

Something seems to be missing from the universe, and the favored model of physics calls it “dark matter” – but despite a century of searching, it remains a no-show. A new paper proposes an alternative ...
