Hi you are familiar with the gravity you feel it, that’s why we are on the earth and not in the air. In the 1800th century a scientist, Isaac, Newton discovered there is a proportional relationship between the gravity and the mass of the object and these is a reverse relation between the square of distance of the objects and gravitational forces, it means that as the distance increase to double the gravitational forces decrease to ¼ of it was before. So that a black hole in the space attract us and we attract it too. A moon too but as it is always and smaller than earth we are yet on the earth.
