Despite dozens of experiments over the years, scientists still don't have a precise measurement for gravity's strength. Why is that?

We take part in a real zero gravity science flight. This is not tourism but an actual research campaign with the European ...

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 ...

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 ...

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 ...

The secret to directly detecting dark matter might be blowin’ in the wind. The mysterious substance continues to elude scientists even though it outweighs visible matter in the universe by about 8 to ...

Monisha Ravisetti was a science writer at CNET. She covered climate change, space rockets, mathematical puzzles, dinosaur bones, black holes, supernovas, and sometimes, the drama of philosophical ...

It's no secret that lab days are some of the coolest in science class. Teacher Lauren Parker and her students at Fort Worth Academy took that cool to truly new heights. Parker got a ticket on a plane ...

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, ...

Jeff Bezos’ rocket company gave NASA a brief taste of the moon’s gravity Tuesday, without straying too far from home. Blue Origin launched the 29 lunar technology experiments to the edge of space from ...
