Nice visualization.

BTW - I have a nagging question from “Brief History of Time” that I have never gotten answered - perhaps you or someone here might know the answer (or could fashion a plausible on.

About midway through the book, Hawking describes how black holes can theoretically lose mass. He talks of matter- anti-matter particles constantly appearing throughout space-time, and that they usually appear and vanish as they simply “cancel” each other out. When they appear on an event horizon, however, if the anti-matter particle falls in and the matter particle of the pair does not (eg - “escapes”) then the hole loses mass.

Question is why would the anti matter particle be any more likely to fall in than the matter.
