According to our current understanding of physics, photons, which are particles of light, do not possess mass and therefore do not directly generate a gravitational field. Gravitational fields are produced by objects with mass or energy.
However, it is important to note that light can be affected by gravitational fields. According to general relativity, the presence of a massive object, such as a star or a black hole, can bend the path of light as it passes through the gravitational field. This phenomenon is known as gravitational lensing and has been observed and confirmed through various experiments and observations.
So while photons themselves do not generate a gravitational field due to their lack of mass, they can still be influenced by gravitational fields created by other massive objects.
