When you deal with massive bodies like the Earth, however, which has a mass of 6 x 1024 kilograms (see How much does planet Earth weigh?), it adds up to a rather powerful gravitational force. That's why you're not floating around in space right now. The force of gravity acting on ...
In the same manner, an astronaut is in free fall under the Earth's gravity but is also moving so fast forward that during the time he's fallen a foot, he's moved far enough forward that the curvature of the Earth has dropped a foot below him. For every foot he moves toward the ea...
The spin of a heavy object, such as Earth, should twist and distort the space-time around it. In 2004, NASA launched theGravity Probe B(GP-B). The axes of the satellite's precisely calibrated gyroscopes drifted very slightly over time,according to NASA, a result that matched Einstein's ...
Gravity can be described in a variety of ways. Here's how Newton and Einstein took gravity from an observation to a measurable phenomenon.

The laws of physics state that when any object which has a density greater than air is propelled upward, it eventually returns to earth because the forces of gravity act upon it. The laws of finance similarly state that markets that go through periods of rapid price appreciation or depreciation...

As effective as Newton’s description is for most purposes, there is something mysterious about it, however. The way gravity seems to act instantaneously over great distances, even across half the universe, bothered Newton himself no end. He thought this “so great an Absurdity that I believe ...
