The concept of "Does Gravity Gravitate?" is based on the idea that gravity, which is the force that attracts objects towards each other, may also have an effect on itself. In other words, it suggests that gravity can attract other gravitational forces, creating a chain reaction.
Currently, there is no conclusive evidence to support the idea of gravity gravitating. While some theories and equations suggest the possibility of this phenomenon, it has not been observed or proven in any experiments or observations.
Einstein's theory of general relativity suggests that gravity is not a force, but rather a curvature in the fabric of space-time caused by the presence of mass and energy. This means that gravity does not act on itself, as it is simply a result of the curvature of space-time.
If proven to be true, the concept of gravity gravitating could have a significant impact on our understanding of the universe. It could potentially help explain the behavior of black holes and the expansion of the universe, as well as provide new insights into the fundamental laws of physics.
Yes, there are ongoing studies and experiments being conducted to explore the concept of gravity gravitating. These include theoretical calculations, simulations, and observations of the behavior of gravitational forces in extreme environments such as near black holes.
