Is There a Law of Nature That is Above Law of Gravity?

Question

That is gravity is a manifestaion or a consequence of this law?

Answer 1

The "Law of Gravity," that all objects fall at the same rate regardless of their mass, is one direct consequence of Newton's Theory of Gravity (which postulates that masses are attracted to one another in proportion to those masses and in inverse proportion to the square of the distance between them). Newton's Theory itself is a consequence of the General Theory of Relativity.

Answer 2

The best theory that explains gravity now is General Relativity. According to this theory, gravity is not a force, but merely just manifestation of the curvature of space-time. Objects that move in this curved space-time will not follow straight path, but they will make curved trajectories. The amount of curvature in space-time is determined by the distribution of mass-energy. For example, the sun that has mass 2.10^30 kg creates relatively huge amount of curvature, whereas Earth that has lesser mass, creates lesser amount of curvature.

But, beside General Relativity, there is also Quantum Mechanics. Quantum Mechanics is totally different from General Relativity, so that physicists can't combine both theory yet. If we succeed to do so, then we will have Theory of Everything. With this single Theory of Everything, we can derive all other formulas and concepts in physics, and we can explain every phenomena that occur in nature

Answer 3

This is the Holy Grail of physics, to find a grand unified field theory that unites general relativity with quantum physics, with gravity being a royal pain because it just won't play nice with the other three fundamental forces of nature:

* strong nuclear force, which binds the constituents of atomic nuclei

* electromagnetism, which acts on charged particles

* weak nuclear force, which causes radioactive decay

So far, all attempts to include gravity at the quantum level has lead to equations that yield infinities (the equations fall apart.)
