We know gravity exists because of what doesn't happen. When we wake up we're still in our beds, not floating near the bedroom ceiling. Gravity is the force that gives weight to objects and causes ...

And in truth, physicists have little idea of what ultimately "causes" gravity, any more than they can tell any of us why the universe exists in the first place. Physicists have, however, produced equations that describe what gravity does exceptionally well, not just on Earth but throughout the cosmos.

What is gravity? Gravity is the force by which a planet or other body draws objects toward its center. The force of gravity keeps all of the planets in orbit around the sun. What else does gravity do? Why do you land on the ground when you jump up instead of floating off into space? Why do things fall down when you throw them or drop them?

So what do we know about gravity? We know that it causes any two objects in the universe to be drawn to one another. We know that gravity assisted in forming the universe, that it keeps the moon in orbit around the Earth, and that it can be harnessed for more mundane applications like gravity-powered motors or gravity-powered lamps.. As for the science behind the action, we know that Isaac ...

So, if gravity pulls everything down, then why don't things on the bottom of the Earth get pulled down into space? In this episode of Crash Course Kids, Sabrina talks about gravity and explains ...

Gravity. The average person probably doesn’t think about it on a daily basis, but yet gravity affects our every move. Because of gravity, we fall down (not up), objects crash to the floor, and ...

Earth's gravity is what keeps you on the ground and what causes objects to fall. Gravity is what holds the planets in orbit around the Sun and what keeps the Moon in orbit around Earth. The closer you are to an object, the stronger its gravitational pull is. Gravity is what gives you weight. It is the force that pulls on all of the mass in your ...

Gravity is the mysterious force that makes everything fall down towards the Earth. But what is it? It turns out that all objects have gravity. It's just that some objects, like the Earth and the Sun, have a lot more gravity than others. How much gravity an object has depends on how big it is. To be ...

As of 2014, science remains uncertain about what causes gravity, which is the attraction between two bodies. However, one theory is that small particles called gravitons are responsible for the force. Scientists continue to search for gravitons and gravitational waves to further the understanding of gravity's cause.
