I recently came across a paper Black Hole - Never Forms, or Never Evaporates. It is claimed that under general evaporation conditions, before particles come into the Black Hole, the Black Hole itself will completely evaporate. In other words, Black Hole cannot form from gravitational collapse.
If this paper was correct, (I haven't went through all the details, but did not find a technical error yet. And I would like to know your opinions about this paper, though i am not sure if it will be an opinion-based question), do we still need to study many paradoxes of Black Holes?
