We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole new model to account for gravity’s influence.

Heading into space means leaving Earth's gravity behind. Astronauts floating around on the International Space Station might look like they're having fun in the weightless environment, but a lack of ...

It's well known that spaceflight causes muscle atrophy and other biological changes in reduced gravity, and especially in ...

Explore 25 science experiments that defied the laws of physics, revealing mind-bending phenomena that challenge intuition.

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 ...

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 ...

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 ...

Engineers have designed a compact, battery-powered radio probe that could help unlock the secrets of alien planets. The proposed small probe, known as the Gravity Imaging Radio Observer (GIRO), would ...

Gravity is the force of action between two objects. It’s called a natural force because it acts at a distance rather than needing to be in contact. Gravity is the force that holds us down on Earth and ...

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, ...
