Their boundery limit pose a problem, and then the entire solution in the extending (prior explosion) the radius is greater the rs, and so all the fellowing integral are wrong. but I will wait for Hawking opinion :)
Just downloaded the PDF, I am not a physicien nor a mathematicien. but from what I read in the article the EQ 13, is the weakness of their argumentation. AA
