So far as I can tell, aladim is proposing that the things we think are black holes are actually parts of galaxies that are traveling away from us at greater than the speed of light, even though most of the galaxy is traveling at less than the speed of light. There are lots of problems with this:

- Nothing travels greater than the speed of light
- A part of a galaxy that is traveling faster than the speed of light while the rest of the galaxy is traveling much more slowly would quickly (in astronomical terms) cease to be part of that galaxy

Most importantly, though, we don't see black holes as blank areas but as small areas of extreme gravitational concentration. There is definitely something very massive where we think black holes are - the only question is whether it's a black hole or something else.
