Gravity is a ubiquitous part of our daily lives — whether we’re being tragically brought to our knees after tripping on the rug or gleefully jumping from a swing’s apex. But despite how common the ...

Physicists have measured the smallest gravitational field ever recorded, in an experiment that could help in the search for a unified theory of physics. Of the four fundamental forces known to physics ...

Twisting bars: the antenna could detect intermediate-sized binary black holes. (Courtesy: NASA) Physicists in Japan have developed a new kind of compact gravitational-wave detector that works by ...

A few months ago, we reported on a theoretical paper that discussed the potential advantages of a gravity wave detector based on a torsion bar, which the creators called TOBA. In the intervening time, ...

We now have the most precise estimates for the strength of gravity yet. Two experiments measuring the tiny gravitational attraction between objects in a lab have measured Newton’s gravitational ...

Here’s a Snapple-cap factoid that’d be fun to whip out in conversation: on a planet the size of a ladybug, objects would fall 30 billion times slower than they do here on Earth. And how do scientists ...

The gravitational constant describes the intrinsic strength of gravity, and can be used to calculate the gravitational pull between two objects. The gravitational pull between two objects can be ...

Gravity is the weakest of all known forces in nature - and yet it is most strongly present in our everyday lives. Every ball we throw, every coin we drop - all objects are attracted by the Earth's ...
