Photons are not massless. Science has proven this. Hubble deep field is a photograph taken by the hubble telescope of distant galaxies billions of miles away. What is unique about this is that you can see light being bent by the gravity of a galaxy cluster. This is called gravitational lensing. It means that there is a larger portion of space being crammed in to your field of view of your telescope than you would normally be able to see. This also makes the same galaxies appear in two different places. I hope this helps.

I am not keen to believe that photons are massless in view of experimental evidence that photons have a mass limit.
Abhas Mitra indicated that the old definiton of Black holes violated the General Theory of Relativity. Hence indicated that Black holes dont exist as such. Therefore the theory of singularity of black holes still remains a question that requires experimental proof.
Good question though.

They follow the curved space know as the event horizon.

gravity affects electromagnetic radiation too
