Key Idea: That Gravitational Field effects Time.
General relativity also predicts novel effects of gravity, such as gravitational waves, gravitational lensing and an effect of gravity on time familiar as gravitational time dilation.
😊The theory of general relativity says the observed gravitational effect between masses results from their warping of spacetime.
😊Although general relativity is not the only relativistic theory of gravity, it is the simplest such theory is consistent with the experimental data.
😊It provides the foundation in support of the current understanding of black holes, regions of space where the gravitational effect is strong enough even light cannot escape.
😊General relativity is also part of the framework of the standard Big Bang model of cosmology.
😊General relativity has developed into an essential tool in modern astrophysics.
