The energy of space itself is not inseparable from gravitation. In physics, the energy associated with the gravitational field is distinct from the energy of space. Gravitational energy is related to the interaction between masses and is described by the theory of general relativity.
The equation E=mc², which is one of the fundamental equations in physics, relates energy (E) to mass (m) and the speed of light (c). It states that energy is equal to mass multiplied by the square of the speed of light. This equation is derived from special relativity and describes the conversion of mass into energy and vice versa.
Gravity, on the other hand, is a fundamental force of nature that describes the attraction between masses. Gravity is not directly related to the equation E=mc². The gravitational force is described by the theory of general relativity, which incorporates the effects of gravity into the geometry of spacetime.
While the equations and theories that describe energy (E=mc²) and gravity (general relativity) are both important in understanding the behavior of the universe, they are distinct concepts. The equation E=mc² describes the equivalence of mass and energy, while gravity is the force that arises due to the curvature of spacetime caused by mass and energy distributions.
