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.

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

The story begins with the black hole information paradox. According to relativity, anything that falls into a black hole is ...

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 ...

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

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 ...

In an astonishing feat of gravitational sleuthing, astronomers have found a mysterious, dense blob of invisible matter ...

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 ...

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

What if the universe remembers? A bold new framework proposes that spacetime acts as a quantum memory. For over a hundred ...

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 ...

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 ...
