A new theory suggests that the unification between quantum physics and general relativity has eluded scientists for 100 years because huge "fluctuations" in space and time mean that gravity won't play ...

The first-ever detection of gravitational waves was made 10 years ago today (Sept. 14). In celebration, Space.com takes you ...

Scientists first detected ripples in space known as gravitational waves from the merger of two black holes in September 2015.

We often marvel at the genius of Albert Einstein, a physicist who revolutionized our understanding of the universe. Yet, even ...

The merger of two black holes is a momentous event, revealing the wildest and most extreme configurations of space, time and ...

After watching that, I joked with a friend that the gravity we feel every day is actually a result of space-time being ...

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 ...

The third Quantum Gravity conference took place at Penn State University from 21 to 25 July 2025, bringing together ...

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 ...
