Explore the complex challenges of quantum gravity in this video, examining the evolution of gravity models and the necessity ...

Photos and videos of astronauts on the ISS show them floating around, but saying there's zero gravity isn't fully accurate.

It's a problem that Albert Einstein identified more than 100 years ago. It's a problem we could be on the cusp of solving, or that could take another century to untangle. And the problem is that we ...

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 ...

"This work is a step toward understanding how quantum mechanics and gravity work together, a major unsolved problem in physics." The first step toward quantum gravity, the "holy grail of physics," may ...

If you want to understand gravity, it makes sense to study black holes. Nowhere else can you find so much gravity so conveniently compacted into such a relatively small space. In a way, in fact, black ...
