为了更好地理解霍金辐射的起源及其对黑洞信息悖论的影响，对1980‘S和1990’S关于Schwarzschild黑洞视界外半经典应力-能量张量的数值结果进行了重新检验。在Hartle-Hawking态和Unruh态下，得到了共形耦合自旋0和自旋1场的四维横向应力的多项式拟合解。对自旋为0的Unruh态结果的分析清楚地表明，霍金辐射的起源不是在非常接近黑洞视界的地方产生对或隧穿，而是一个扩展到r=3M以外的非局域过程。论证了黑洞信息悖论不能通过发生在一个几何形状接近Schwarzschild的大黑洞的视界上或非常接近该视界的过程来解决。
Numerical results for the semi-classical stress-energy tensor outside the horizon of a Schwarzschild black hole obtained in the 1980's and 1990's are re- examined in order to better understand the origin of Hawking radiation and the implications for the black hole information paradox. Polynomial fits to the numerical results for the 4D transverse stress are obtained for conformally-coupled spin 0 and spin 1 fields in the Hartle-Hawking and Unruh states and. Analysis of the spin 0 Unruh state results clearly shows that the origin of the Hawking radiation is not pair creation or tunneling very close to the black hole horizon, but rather is a nonlocal process extending beyond r = 3M . Arguments are presented that the black hole information paradox cannot plausibly be addressed by processes occurring on or very close to the horizon of a large black hole whose geometry is close to Schwarzschild.
