Black Holes as Accelerators

Guillermo Gonzalez has this to say about this connection:

"The existence of natural accelerators that we can observe is certainly a candidate for the correlation I discuss in my book.
An expert on the giant black hole at the center of our galaxy has stated that there are a number of coincidences that allow us to get good observations of it. This is another case where I am trying to understand the subject a little better to appreciate his findings."

Curiouser, and curiouser.
