General relativity is a theory of gravitation established by Einstein in geometric language. He rephrased gravity as a space-time bent by matter and energy in space-time to replace the traditional view that gravity is a force, and this space-time curvature It is directly related to the energy and momentum of matter and radiation in space and time. According to the above definition, the phenomena in the following options that do not involve general relativity are:. ['Scientists observed when observing a total solar eclipse, and the light produced a deflection when it passed near the sun.', 'Scientists have found that the clock moves slower in a strong gravitational field, so the light emitted to the earth from the surface of a massive mass will move towards the red end of the spectrum.', 'Scientists found that when a star is dense enough, its gravitational force distorts areas in space and time so that light cannot escape, thus finding the existence of black holes.', 'Magellan found that when sailing towards a distance, the sail gradually sinks, and finally disappears into the line of sight, while the sea level appears to be curved, and the water in the distance seems to be lower than the water level in the vicinity.']
