They all agree that Hawking radiation does exist.
But they also agree that General and Special Relativity are perfectly correct, yet none of them can explain in any reasonable way why the universe seems to be defying the laws of physics by continuing to expand and accelerate in that expansion. So either we as a historically flawed human community are incorrect(or partly incorrect) about our understanding of the laws of physics, or the universe is misbehaving(bad universe! naughty universe!). Which do you think is more likely?
Hawking Radiation does not exist. Two reasons. 1. Matter inside the event horizon is not physically a part of the singularity that is causing said event horizon. 2. Once a any particle enters a singularity, it does not come out until released by a certain type of event.
The process Hawking described can take place with particles inside the event horizon but not the singularity itself, this means that the area between the event horizon boundary and the singularity itself can have matter extracted using the Hawking principle, but only if matter is present in that area.
X-ray emissions from just-formed white dwarfs (a.k.a. black holes) do exist but not for the reason Hawking or others argue.
Good grief you need to stop..
