Gravity used to be the most down-to-earth of ideas, the thing that kept apples falling and planets in line. Now a growing ...

Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever tabletop experiment, researchers at Leiden University in the ...

Russia has quietly taken a science fiction staple and turned it into a legal blueprint, securing a patent for a rotating ...

When two black holes merge or two neutron stars collide, gravitational waves can be generated. They spread at the speed 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 ...

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 ...

The Juno spacecraft now orbiting Jupiter has a suite of science instruments which will investigate the existence of a possible solid planetary core, map Jupiter’s intense magnetic field, measure the ...

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, ...

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 ...
