Gravity can be described in a variety of ways. Here's how Newton and Einstein took gravity from an observation to a measurable phenomenon.

Einstein also says this occurs due to gravity — but in his theory, gravity is not a force. It's a curve in space-time. According to Einstein, those objects are still traveling along the straightest possible line, but due to a distortion in space-time, the straightest possible line is...

Discusses how gravity affects life on Earth and other planets. How spacetime bends in response to the presence of things in it; Consideration of how a straight path responds to a three-dimensional motion at a constant velocity in spacetime; Role of gravitational acceleration; How the curvature ...
Other planet's gravity The strength of an object in space gravity is directly proportional to the size of the object. The bigger an object is, the stronger its Gravity is. The Earth has a gravity of 2.6 times the gravity of Mars. 1 or to look at it another way, Mars has .375 the...
This is called gravity. Gravity pulls from the center of the Earth.So things fall down to the ground because of gravity.Do you know what would happen without gravity?Everything would float around in the air.When you fly high away from the Earth into space, you will float around. 重力...

This is the reason astronauts have a time limit on how long they remain in space. Because it is weakening their body, which has consequences when they return to Earth. Studies show that if you were to spend around three months in space, without gravity, then it would take two to three ...
