Gravity
No. Gravity is not a substance. It is an attractive force between objects with mass.
The answer is gravitational attraction. It is the attractive force between all objects that have mass. It's between you and me, you and your PC, and between everything.
-- Electrical force only cares about the charge on two objects, and ignores their mass. Gravitational force only cares about the mass of two objects, and ignores their charge. -- Electrical force can be attractive or repulsive. Gravitational force can only be attractive.
Gravity is the attractive force between two masses. The greater the mass, the stronger the attraction.

Gravity is an attractive force that occurs between all objects with mass. The gravity of any planet will pull objects in.
A distortion of space
Gravity is not a substance. It is not "made" of anything in that sense. It is an attractive force between objects with mass caused by a distortion of spacetime.
when the mass of either object increases, or the distance between their centers decreases. It is the attractive force that is affected by the mass of each object or the distance between them. Even though it cannot be proved from 1st principles, the attractive force relationship between the 2 objects is given by (m=mass, d=distance): m1 x m2 --------- d2 Thus, the attractive force increases when either m1 or m2 increases. This force also increases very much (as the square) when the distance decreases.
That it was a universal attractive force between two objects with mass, no matter how distant from each other they are.
Gravity is the attractive force between two masses. The greater the mass, the stronger the attraction.
They don't. The attractive force between two objects is due to gravity. Black holes behave exactly like any other mass in this respect.
