In the article "Why does light have invarient speed?" on PF (first URL in attached file), there is a statement that for photons, m_0 = m \sqrt{1 - \frac{v^2}{c^2}} is 0 since v = c. (I'm not sure if the author is stating this or quoting somebody else.) Is this a valid...

I disagree. The radiation cannot start before the horizon forms, that is, before the black hole forms. By definition, it is something that happens near the horizon of an existing black hole. I would be interested to hear in what sense can Hawking radiation start before the event horizon is...

As I understand it, a black hole is supposed to evaporate through Hawking radiation after a long but finite amount of time. Also, the radiation encodes in some sense the information of the matter that fell into the black hole. This according to an observer ("Alice") outside the event horizon...
