Completely agree... It's similar to the current situation with cars... Hybrids. Most of them run on electricity + petrol. Technology is developing gradually just like anything else in our Universe.
No one has ever witnessed a real black hole as I understand. Correct? Of course, all the evidences indicate such an object does exist. But what if it is just the gravity of all stars that center of a galaxy (quasar) consists of creates these spirals of matter?
It works in our consciousness limits only, I guess... I tend to suppose that we are all looking at some simple structure that is just beyond our mind... Similar to an ant watching at a computer monitor or chimpanzee making sex.
