    Do the light have mass?

    If yes then why quantum physics does not believe it. And if no why it is attracted by Black-hole.

    I think you need a physicist to answer this - maybe read Stephen Hawking's books, or Einstein. I am NOT a physicist. This is my understanding of it. Light is supposed to act like both a wave and a particle, though the particle doesn't have mass, that I know of. Light is affected by gravity, that is how astronomers can tell whether a sun has planets, by the effect of the planet on light (and other things). A black hole has enormous gravity. Nothing can escape its clutches, even light.

    Has something to do with quantum entanglements and a photon falling into a black hole is a frequency shift made by the curvature in space-time continuum. It's black because it's over the event horizon.

    From -
    "There are no discrete particles, only forces, but in the math equation, when someone says what does that number mean, it's thought as a separate entity - a particle. The reducing of a thing into separate parts is what lies in the problem of understanding quantum mechanics."

    according to the persisting theories (theories to satisfy various behaviour of light in several events) it depends on which model of light you are taking to satisfy the any specific property of light successfully. so wave models dosen't simply require the need of any parameter of mass to rely upon for thier existence, mathematically they could exists on papers without having mass. however, giving mass to wave would defy wave theory in simpe model. And other models of light they simply require the mass parameter as u may be konwing.

    In general saying as these are individual therories these kind oddities could happen,but combining these theories to get upon a fundamental model may just help solve the problem.(which has not happend yet).infact many physicists have turned to a more unique physcial model to define everything- string theory.
    at last who knows may scientist drop the parameter of mass and find a more richful than this to satisfy all its properties.

    No; light is made up of massless particles called photons. The black hole thing is weird; the black hole bends space and time around it, and the light travels through the curved spacetime towards the black hole. If crosses the event horizon - then the speed needed to escape the black hole is greater than light speed. That is, spacetime is too curved, and every path the light can possibly take leads to the singularity at the centre of the black hole.
