Every time a coffee mug drops, a satellite orbits or an astronaut floats, we are watching the same phenomenon play out under very different disguises. For centuries we have treated gravity as the ...

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 “gravity hole” formed at least 70 million years ago after convection in Earth’s mantle. The weak gravity could impact our ...

Gravity may seem constant, but it actually varies across the planet—and one of the strangest places is Antarctica, where gravity is slightly weaker than expected. Scientists have traced this “gravity ...

We are all familiar with the concept of gravity, from the force that keeps us firmly on the ground, to the phenomenon that explains the orbits of the planets in the Solar System and the whole ...

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 ...

If you’re superstitious, a black cat in your path is bad luck, even if you keep your distance. Likewise, in quantum physics, particles can feel the influence of magnetic fields that they never come ...

A conspiracy theory that spread on social media claims that gravity will disappear for seven seconds this August, and that NASA is aware that this will happen. A physics professor explains why this is ...

Gravity, in the literal sense, keeps everyone (and everything) on Earth grounded. It acts as the anchor that prevents objects from floating skyward. For humans, it’s a leash that stops us from ...

The best way to find buried treasure may be with a quantum gravity sensor. In these devices, free-falling atoms reveal subtle variations in Earth’s gravitational pull at different places. Those ...

In the April 1981 issue of Popular Science, we explored the many initiatives and techniques used in the exciting hunt for sensing gravity waves, then out of reach. By Bill Gourgey Published May 18, ...
