Does gravity gravitate? Would the following link be of any relevance? http://en.wikipedia.org/wiki/Stress-energy_tensor"

The concept of gravitation is the natural phenomenon by which all objects with mass are brought towards each other. This is commonly known as the force of gravity.
This question refers to the idea that gravity itself may have a gravitational pull. According to Einstein's theory of general relativity, gravity is not a force but rather the curvature of spacetime caused by the presence of mass. Therefore, gravity does not technically "gravitate" in the traditional sense.
The law of universal gravitation, formulated by Sir Isaac Newton, states that the force of gravity between two objects is directly proportional to their masses and inversely proportional to the square of the distance between them. This law explains how objects are attracted to each other due to their masses, which is the basis of the concept of gravitation.
While the terms are often used interchangeably, there is a subtle difference between gravity and gravitation. Gravity refers to the force that pulls objects towards each other, while gravitation refers to the concept and study of this force.
The concept of gravitation has evolved significantly over time, with contributions from scientists such as Newton, Galileo, and Einstein. It has gone from being seen as a mysterious force to being understood as the curvature of spacetime caused by mass. Our understanding of gravitation continues to evolve as scientists study it further through experiments and observations.
