Gravity used to be the most dependable rule in the cosmic rulebook, the quiet background force that never changed its mind.

With the ability to generate thousands of times the G-force of Earth and to handle as much as 1,900 tons of mass combined ...

There are some things in life that just sort of happen. Desks get covered in dust and scraps of paper. Clothes get dirty and the laundry basket fills up. Weeds slowly creep across an untended ...

The mystery of dark matter—unseen, pervasive, and essential in standard cosmology—has loomed over physics for decades. In new ...

What happens to soft matter when gravity disappears? To answer this, UvA physicists launched a fluid dynamics experiment on a sounding rocket. The suborbital rocket reached an altitude of 267 km ...

A rift runs deep through the heart of physics. The general theory of relativity, which describes gravity, clashes with quantum physics. In an effort to seal that physics fissure, untold numbers of ...

Artificial gravity remains the stuff of science fiction. But dealing with microgravity causes significant problems in many astronauts, ranging from bone deterioration to loss of sight. An alternative ...

Lots of people, including Einstein (see above), talk about gravity, the restraining force which makes people walk on floors instead of floating in midair. What worries Roger Babson, 74, economic ...

A clear look at how physics defines gravity, from Newton’s force-based model to Einstein’s view of curved spacetime, and why the distinction matters in modern science.
