Well Son says vacuum catastrophe does not exist, never has. Because a paper points out that it is all imagination. Hopeless..
The term hopeless more appropriately applies to someone who objects to certain conclusions because they appeared in a technical paper (that they haven't read) while ignoring the fact that their own claims also appeared in technical papers (that are nearly a half century old and that in all likelihood they also haven't read).
Plus, of course, the fact that Son never said the problem never existed; he acknowledged that it existed and explained why it no longer exists.
