So light can be bent by a gravitational field, and follows the curvature of spacetime. does light have a gravity field of its own? does light bend spacetime?
According to Einstein's theory of general relativity, the presence of mass and energy in space can cause spacetime to curve. Light, which has no mass, is still affected by this curvature and follows a curved path as it travels through spacetime.
Yes, the bending of light by massive objects has been observed through various experiments, such as the deflection of starlight near the sun during a solar eclipse.
No, light only bends spacetime when it passes through regions with a significant amount of mass or energy. In empty space, light travels in a straight line.
According to the theory of relativity, time and space are intertwined and can be affected by the curvature of spacetime. This means that time can appear to move slower or faster depending on the strength of the gravitational field.
Yes, gravitational lensing occurs when the path of light is bent by the gravitational pull of a massive object, causing the light to appear distorted or magnified. This effect is a result of the bending of spacetime by the mass of the object.
