So um... the cloud is 28000 light years away? Since everyone whos takin physics 101 should know that nothing can travel faster than the speed of light because as your speed increases, you mass becomes greater. When you reach light speed, matter streches and becomes heavier (oversimplified), and your mass becomes infinite once you hit light speed. Using this fact, it would take over 28000 years to even reach us, and by then I hope we would have a way of distorting the cloud, if it were true.
And nothing can really excape a SMBh (super massive black hole) pull. Steven Hawking has discovered a new type of radiation, oddly enough called Hawking Radiation. Because the Black Holes are a void in the space-time, they can consume massive amounts of mass without stopping (yes they stop once they are full, so to speak). Black holes release single atoms at a time over their existance, Hawking Radiation, and once all the atoms are gone, the black hole will dissapear. But to put it simple, there is something like 2.4 trillions atoms in a gram of anything (roughly) and if you consider how much mass is consumed by just 1 star, it would take a very, very long time for a black hole to die, something along the lines of 1 google (10^100) years for a normal black hole. Ah now isnt physics fun

i dont think thats entirely correct. conditions in a particle accelerator are worse than almost anything a particle can experience in space, and black holes have been created in there before...it is called evaporation when the black hole "dries up" and ceases to exist. it definitely happens faster than a googol. it is more like half that.

Sorry googol. Anyhow, its been a common law of physics that nothing can exceed the speed of light, no ifs ands or buts. How would conditions be any different inside a particle accelerator and than space, besides temp? Light, in a vacuum is something like 176000 miles per second (I dont remember). As I said before, matter stretches as it goes faster, a minute amount, but at the speed of light the matter stetches to such a degree that its mass is infinite.
There is also a difference between a black hole the size of an atom and one that comes from a sun. Since a black hole that comes from the sun size is actually something like a few hundred feet, it would have considerably more gravitational pull. I also ment that the SMBh had a life of a googol, not a smaller one. It has been discovered that there are actually SMBhs that have stopped feeding (they absorb too much mass?) and just become dormant black blobs in space. I dont know of any galaxies off the top of my head that have a dead SMBh because I only know of the Milkyway and Andromida. It is evident because some galaxies have actually stopped their spinning and the objects (stars) that occupy the spiral, or whatever type the galaxie is, start fly off into the direction they were headed in before the gravity turned off. Oh heres another example of the max speed of light, Hawking discovered that gravity has the same speed of light (mathematically of course). You can also witness this in the spiral galaxies I mentioned above, the inner stars are not rotating, heading off in the proper direction, while the outer stars are still orbiting in their usual path, so the outer stars one by one lose their orbits. If gravity was instantanious, then all of the stars would release from their orbit right away.
Ok Im done talking, too much here.

Wow...I'm just impressed we could pull a reasonably scientific discussion from a thread begun under the wonderfully and oh-so-fake guidance of the Weekly World News...wow
By the way, boxoreds, there are a few reputable articles indicating scientists BELIEVE they have created a black hole under laboratory conditions in a particle accelerator. Check out the linkys, they're from BBC and National Geographic for the sake of using at least some reputable sources in this thread...
National Geographic Article
BBC Article
Hope that sheds some light on the situation...
