I am wondering how a wave, light, can be affected by a black hole as has
been seen by the Hubble space telescope. This goes deeply into the
nature of light it self, like how is a wave with no real mass affected?

Photons have mass because of their velocity (speed of light). m = E/
c^2 Photons have no rest mass but they are never at rest. An
experiment long ago proved Einstein to be correct when he claimed that
light was affected by gravity. A black hole is no exception.

And if you read that article you will find it says that space itself is
warped which means the path is changed and not that the photons are
put on a different path because they have mass.
