There are two representations of black holes that I see in the popular media. Could you help me find the answer to a (or two) question about this please?
1. Feeding black hole with an accretion disk - I assume that the accretion disk is a product / consequence of rotation (in addition to the feeding) ... but we all know what they say about assumptions ... ?
2. A black hole passing in front of a star field, causing gravitational lensing. I don't know if these are rotating, or where to start looking for discussions on the topic. Any ideas?
Basically, do black holes always rotate? Any pointers / suggestions would be greatly appreciated.
Regards,
Noel.
