Gravitational Quote by Abraham Pais
““He understood that the sources of the gravitational field were not just ponderable matter but also field energy. He realized that gravitational field energy is to be included as a source and that the gravitational field equations were therefore bound to be nonlinear.””
About This Quote
Source Book: “Subtle is: The Science of Particle Physics” by Abraham Pais, 1982
Gravitational fields arise from matter and energy, making Einstein’s equations inherently nonlinear.
In simple terms: Gravity comes from both matter and energy.
