First of all, I have to say that I'm not sure if my post is on the good forum. If there's any problem about that, just tell me where i should post it.

So my question is, why light can de be absorb by black holes if light has no mass. I mean if black holes have enormus gravitational force it still need to have an object with mass to be absorb?

Thanks

In general relativity (the more modern theory of gravity) mass/energy (such as a black hole) curves spacetime. Things (particles, photons, etc.) follow paths in the curved spacetime. This can be manifest as a black hole absorbing light. No photon mass is necessary.
 
Um...I think this was an easy one for you. Thanks. I will review Einstein Theory of relativity.
