I don't take Hawking as gospel, he is merely trying to construct a theoretical / mathematical model for the pyhsics of extreme environments that definitely go beyond relativistic environments. He is stating possible rules for his construct - which we are a long way from scientifically proving yet!

I must re-read the black hole envapouration scenario - as I didn't get that the "swallowed" virtual particle has negative mass = negative energy = negative entrophy. That gives me a fair headache.
