what happen if the gravity comes in the place where there is no gravity?
Gravity is a force created by any body that has mass. We usually think of the Sun, Moon, and planets (especially Earth) as objects that have gravity, but you and I, because we have some mass, also exert a gravitational force — albeit a really tiny one!

If there's gravity in space, why does it look like the astronauts are floating? The reason is that objects in space are in a continuous state of free fall. This term describes a state of motion with no acceleration other than that provided by gravity. A similar thing could happen on Earth to an elevator passenger and her purse, both of which would be equally "weightless" if the elevator fell rapidly enough.
