Newton's theory of gravity posited instantaneous gravitational attraction, successfully predicting planetary orbits. Einstein's special relativity challenged this, necessitating the development of ...

Legend has it that Isaac Newton had the moment of inspiration that would lead to his theory of gravity when, on a warm ...

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 ...

In 1797 Henry Cavendish, one of Great Britain’s leading scientists, built a contraption to weigh the world. At the time, Earth’s mass was unknown, as was its composition. Was it mostly solid rock? Did ...

Mutual attraction: why is it so difficult to pin down the gravitational constant? (Courtesy: iStock/FrankRamspott) Two extremely precise measurements of the gravitational constant G have yielded ...

Until now, we’ve only detected gravitational waves originating in binary systems, from the merger of black holes or neutron stars. But researchers from Northwestern University have potentially ...

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 ...

Pennsylvania’s largest amusement park is adding a new attraction in 2025. Hersheypark is adding the Twizzlers Twisted Gravity attraction when it opens the park next year. In the just over minute-long ...
