As I was reading about photons, Some of the information was puzzeling for like; photons have no mass or that they dont have a kinetic energy.

I understood having a zero mass at rest but when traveing with the speed of light the photons should gain a mass ( I think ) because of 2 universal evidences 1) The space-time curvature of a body such as a star causes the gravitational lensing and should the light have a mass to be affected by the mass of the sun? 2) The light is completely trapped in a black hole because of its extreamly intense gravity or the space-time wrapture so should it have a mass to be effected by the gravity?

The next was about the Kinetic energy of light but if I understand the problem with the mass I will sure solve this one myself

I'll be really thankfull for your answers.

To make much more clear what I mean is that; If and if photons gain a mass due to their speed they probably have a kinetic energy too. right?

If so than E= (2ke/c^2)c^2 which means E=2ke which again means:

E=2(mv^2/2) where v=c so E= mc^2 And this shows that the mass is directly proportional to its speed and that the mass is variable at least in case of Electromegnatic rays...??

Now I'm 15 years old and I haven't yet studied the other types of masses expressed in many of the posts. so I would thankfull for using simple forms of explanation, THANKYOU.......
