There's No Gravity?

It's like floating in the outer space!

Gravity is the force of attraction between celestial bodies. It is the force that keeps the planets on their orbits as they revolve around the sun, the same force that holds the moon as it revolves around the earth. It keeps us from falling into the outer space and it makes us fall as we climb up in a tree.

Living in a zero gravity environment  is unimaginable if not impossible. This environment does not permit  occurrence of ecological processes needed to sustain life.
