The Earth's gravity comes from the mass of the Earth itself. Everything in the universe has gravity, some more and some less depending on size. Space is like an empty hole or area, so it doesn't have any weight, hence it has no gravity. If it did everything in the universe would be pulled together because of the enormity of it.
Actually, gravity is everywhere. But, this gravitational force depends on the product of the masses of the objects, which attract each other, and on the distance between them. The smaller the mass, the lower the attractive force. The larger the distance between the objects, the lower the attractive force (gravitational force decrease with the inverse square of the distance). Thus, the objects are more remote from another mass objects in the space than on Earth. Consequently, they are subjected to lower gravity.
Actually, there is gravity in space as well. It used to be believed that space was just that, space when in fact, it has been discovered to be dark energy. Any item sent into "space" will start to rotate creating its own gravity. Gravity is the attraction of items, whether it be matter or energy
There is Gravity in space but you just don't notice it until it it the same size as earth.The higher the mass is the higher the gravity force is.Everything you see in space has gravity. The Sun's gravity keeps Earth in its orbit. Without the Sun Earth will float away.
There are many planets in space following their own gravity. The gravitational force among the planets cause things to stay constant in space as vaccuum. So, why there is dark in space.
All the material things have gravity. In pace all the planets, stars and other celestial bodies have gravity but space itself is a vacuum so does not possess gravity
Because earth is moving around itself which creates gravity the same principle that we use for artificial gravity in spaceships. And space is vaccum no matter ,the gravity in space is just that possesed by planets etc that r in it.
