Legend has it that Isaac Newton had the moment of inspiration that would lead to his theory of gravity when, on a warm afternoon, he saw an apple fall from a tree and wondered why it should fall down ...

Gravity is the reason things with mass or energy are attracted to each other. It is why apples fall toward the ground and planets orbit stars. Magnets attract some types of metals, but they can also ...

You may have heard people say that aboard the International Space Station (ISS) there's "zero gravity," but in fact, gravity is still very much present. The station orbits Earth at an altitude of ...

Early on in science classes all over the world, students drop diverse things to learn how gravity works and how outside forces might affect the rate of fall. But the science of falling goes well ...

hello all, i was thinking about gravity the other day and how its force might be similar to molecular bonding. Think about the molecule SO2. What if earth is like the S and the O's are just the people ...

As physicists search for a theory of quantum gravity, new results show that classical gravity can still interact with quantum fields to allow matter to become entangled. When you purchase through ...

The gravitational force is by far the weakest of the four forces of nature. It’s simple to defy gravity: just lift something in the air. But the annoying thing about gravity is that it’s both ...
