 evidence for and evidence against black holes.
I have seen M-87 in my Telescope and under very high magnification the Jet was detectable. I will post alternative theories about this at another time.

Evidence against?
No, I have read many books about space, but I have never come across evidence against the existence of black holes. The theory is sound, a lot of evidence have been found, and the effects of blacks holes observed and verified. I can't see how anybody can dispute the existence of black holes scientifically. To me it is a done deal. It would have to be very compelling evidence to convince me otherwise, and the peer review will have to be very credible. This is one opinion that will be difficult to budge me off.

The problem with Black holes is that we know so little about them. We can make educated guesses, based on the laws of nature we have discovered, but our rules might break down when things get very small AND very heavy. Also, the concept of the singularity at the centre of a black hole makes no sense. You just can't put numbers into an equation about nature and return an answer of infinity, that's a clue that your model is wrong. You don't need a singularity for black holes to exist of course, but as of yet we know of nothing that would keep one in a state of hydrostatic equilibrium.

excellent point!!
i look at black hole theory as a working model. Not yet fact but close to it, until proven beyond question. I have a photograph i took somewhere of (i will retrieve it) a supposed black hole in action. And will put it on my profile page. In the meantime Itchy knows more about phisics then i do(as my study is directed toward Biology) and any questions about the mechanics of such a strange phenomena should be directed to him.

black holes
I always thought black holes were the vacuum left by the implosion of stars and a gravitational collapse of the surrounding area. And that everything within its gravitational radius would then get sucked into it. I also though there has been several satellite photographs where this phenomenon seems to have been observed. They have done some pretty cool simulations using 3D monte carlo to try and work out what happens they seem to have worked out the external gravitational physics but as what happens once things enter the black hole is a complete mystery. Put it this way if someone said that it was a wormhole to another universe you still would not see me going anywhere near it. To put it in plain language I think of them more like giant scrapheap condensers. en.wikipedia.org
