Gravitational lensing is a phenomenon in which the gravitational pull of a massive object, such as a black hole, bends the path of light passing by it. This can cause an object behind the massive object to appear distorted or magnified to an observer.
Gravitational lensing does not distort images of the sun around a black hole. This is because the sun is relatively small compared to the size of the black hole, and the gravitational pull of the black hole is not strong enough to significantly bend the light from the sun.
The amount of distortion caused by gravitational lensing depends on the mass and distance of the massive object. In the case of a black hole, the distance between the sun and the black hole is too large for the gravitational pull of the black hole to significantly bend the light from the sun.
Yes, there are other factors that may affect images of the sun around a black hole, such as the presence of other massive objects or the effects of spacetime curvature near the black hole. However, these factors would have a smaller impact compared to the gravitational lensing effect.
Yes, gravitational lensing can also occur due to the gravitational pull of other massive objects such as galaxies and galaxy clusters. This phenomenon has been observed in various astronomical observations and has helped scientists to gain a better understanding of the distribution and behavior of matter in the universe.
