Question: Why is there no gravity in space?

Ben Still answered on 24 Nov 2011:

There is – it just depends how close you are to a massive thing. Gravity is pretty weak and really only experienced to be a decent sized force when you are really close to a massive thing like on the surface of a planet.

The weightlessness that we see in videos of people in the Space Shuttle and International Space Station is not because there is zero gravity but instead because they are constantly falling toward the Earth. They are high enough that this falling allows them to continue in orbit around the Earth, but they are falling none-the-less. The falling is balancing out the very little gravity that there is that far from the surface of the Earth – making it seem that there is no gravity.
