: : Give me an opinion about the existence of black holes.......do they exist?? or don't they??

: en realidad se muy poco a cerca de orion pero no se descarta la existência de un black hole en esta reguiôn del espacio.

I think black holes must exist - they work out mathematically, and help to explain so many things that cannot be explained in any other rational way. One of the best sources of evidence is the extreme rate of speed at which some stars move around the center of galaxies in an extremely compact form, and also the huge amounts of energy and antimatter generated at these locations (including our own Milky Way). At this point, I don't see any other explanation; I'd put my money on black holes any day (without necessarily living long enough to see a return on the wager!)...Bruce
