Strong gravity refers to the force of attraction between two objects with mass. It is one of the four fundamental forces of nature, along with weak nuclear force, electromagnetism, and gravity.
Strong gravity is significantly stronger than other types of gravity, such as the force of gravity between two objects on Earth. It is also responsible for holding particles together in the nucleus of an atom.
Strong gravity plays a crucial role in the formation and behavior of black holes. When a massive star dies, its core collapses under the force of strong gravity, creating a singularity and surrounding event horizon that defines a black hole.
Yes, strong gravity can be observed and measured through various methods, including studying the motion of objects around massive bodies, observing the effects of gravitational lensing, and using gravitational wave detectors.
No, strong gravity and the theory of general relativity are not the same. General relativity is a theory that explains gravity as the curvature of spacetime, while strong gravity is a force that acts between objects with mass.
