Cheap Astronomy answers more deep questions with gravity.
The Milky Way is totally warped!
And Curiosity is measuring Martian gravity ! #365DaysOfAstro
Steve and the Cheap Astronomy team investigate some fuzzy concepts with gravity.
Today, we understand gravity much better than we did in Galileo’s day, thanks to Albert Einstein. Over 100 years ago, Einstein came up with a theory of gravity that has so far passed all tests, in laboratories and out in space.

Scientists manage to map a highly detailed gravity map of our planet. And it turns out, this is very useful for other worlds too.
Seriously, What is Gravity? Another story of gravity about How did Einstein develop General Relativity? What does it mean for different kinds of masses to be equivalent? How does gravity do what it does? Why is curvature so important in understanding gravity?
How long would it take for the gravitational well created by the Sun to disappear, and the Earth and the rest of the planets fly off into space?
