It’s been demonstrated since the 1500s that, when falling toward a certain body, objects fall at the same rate. Everyone from Galileo in Pisa to David Scott on the moon demonstrated that. But what if ...

Gravity is a fundamental force of nature; it is an attractive force between any objects that have mass. The strength of gravity between everyday objects, such as a desk and a chair, is extremely small ...

Source: NOVA: "Galileo's Battle for the Heavens" This resource was adapted from NOVA: "Galileo's Battle for the Heavens." Galileo thought a great deal about the motion of falling objects. Specifically ...

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 ...

Once again, physicists have confirmed one of Albert Einstein's core ideas about gravity — this time with the help of a neutron star flashing across space. The new work makes an old idea even more ...

Albert Einstein’s been having quite a few weeks! First his “imaginary elevator” thought experiment was confirmed with unprecedented precision, then his theory of relativity was shown to create ...

DIVIDING a falling cloud of frozen atoms sounds like an exotic weather experiment. In fact, it’s the latest way to probe whether tiny objects obey Einstein’s theory of general relativity, our leading ...

Babies love it, and Galileo supposedly tried it: Drop some objects from on high, and see how fast they fall. According to Einstein’s theory of general relativity, all objects in Earth’s gravity, ...
