Every time a coffee mug drops, a satellite orbits or an astronaut floats, we are watching the same phenomenon play out under ...

The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study ...

General relativity explains gravity as the distortion of space-time. Quantum mechanics explains other forces using exchanged "virtual particles." Unifying gravity with quantum mechanics is a major ...

Can we create artificial gravity, or is it still science fiction? In this video, we break the problem down using real physics ...

In a bold step toward solving one of science’s most puzzling problems, researchers have proposed a new way to bring gravity into the same mathematical language as the other forces of nature. While the ...

Now for the first time, this controversial theory has been tested experimentally and has held its ground. An independent study of the distribution of gravity around more than 30,000 galaxies found ...

The standard explanation has been dark energy, an invisible force added into the equations to make the math work. But now, an ...

Of the four fundamental forces of physics, gravity is the one we’re most familiar with in everyday life, but it’s also the only one that can’t currently be explained by quantum physics. Now scientists ...

Despite decades of searching, the "dark matter" thought to hold galaxies together is still nowhere to be found. Matthew Chalmers describes how some physicists think it makes more sense to change our ...
