The general theory of relativity proposed by Einstein believes that space and time will bend due to the existence of matter, and the gravitational field is actually a curved space-time. Einstein believes that the sun is a large gravitational field. A deflection of 1.7 seconds will occur on the surface of the sun, and this prediction was finally confirmed by astronomical observations. Can't launch from this? ['The closer the starlight is to the sun, the greater the impact.', "The deflection of the starlight is related to the magnitude of the sun's gravity.", 'General relativity is based on astronomical observations.', 'Science gives reasonable explanations for many incredible phenomena.']
