Gravity is the result of the curvature of space due to the stress-energy tensor, which is the relativistic summary of the distribution of mass, energy, momentum and sheer stress.Gravity is a property of matter. Matter has properties that are not physical. Gravity exists in all matter. The larger the volume of matter, the more measurable the gravity becomes. In very large bodies like planets, gravity can be easily measured, however in small objects like a rock, gravity may not be easily measured. Gravity is a function of mass and volume. This is cutting edge science! Gravity cannot transcend space and time. No property of matter can exist without matter.
