Hi Karl I still don't understand how you find these black holes even if you are not sure they are black holes. I am intrigued by by their concept but they have always confused me. You have made the comment that you don't know if black holes are black holes. This is why I am confused. Can you recommend somewhere I can go to [web site] where I can learn more about this. I would appreciate it if you could suggest a good resource. Thanks.
