General relativity is a theory developed by Albert Einstein that explains how gravity works. It is based on the idea that gravity is not a force between masses, but rather a curvature of space and time caused by the presence of mass and energy.
Newton's theory of gravity is based on the idea that gravity is a force that acts between masses, while general relativity explains gravity as a curvature of space and time. Additionally, general relativity takes into account the effects of gravity on the flow of time and the bending of light.
Einstein's theory of general relativity revolutionized our understanding of gravity and the universe. It has been confirmed by numerous experiments and is the basis for modern theories of cosmology and the study of black holes.
According to general relativity, massive objects cause a curvature in space and time. This curvature can cause light to follow a curved path, known as gravitational lensing. The more massive the object, the greater the curvature and the more pronounced the bending of light.
Yes, general relativity has been extensively tested and verified through various experiments and observations. For example, the bending of starlight during a solar eclipse, the precession of Mercury's orbit, and the gravitational redshift of light have all been confirmed to be in line with predictions from general relativity.
