"A black hole is an astronomical object with a gravitational pull so strong that nothing, not even light, can escape it." - NASA*
You're wrong. If that feature would be correct, then one of that kind of super massive object would pull entire Universe many millions years ago.
"A black hole’s 'surface', called its event horizon, defines the boundary where the velocity needed to escape exceeds the speed of light, which is the speed limit of the cosmos." - NASA*
You're wrong again. Light is distracted on sort of "surface" of that astronomical object, and that more of light particles makes the area by this object much brighter.
Matter and radiation fall in, but they can’t get out. - NASA*
No, that is not what happen there. If that would happen, all black holes would explode finally because of overloading.
