Will we get swallowed by renegade black holes?

So here's the deal. We know that black holes have such an immense gravitional pull that not even light can escape and that is sucks up all matter it comes across. As Dr. Michio Kaku stated, in a recent blog: "If you shoot a nuclear weapon right into a black hole, the effect would be smaller than a pinprick compared to the enourmous gravitional pull of a black hole itself."
Now try and put this into context. We know how powerfull a nuclear weapon's blast is, but compared to a pinprick in the scheme of a black holes force of gravitional pull! Wow consider such a force. If only we could harness such a force. We of course never will though. Dr. Kaku also made the statement that if a black hole ever got a billion mile away from our solar system that it would cause a disruption in the earth's orbit, thereby causing a change in tides. Well it probably would cause disruptions in other planets and possibly our own Sun as well. Can we say SOLAR FLARES? So why is this information vital? I mean the closest black hole is billions of light years away, too far to even send a probe to it. Which is why the particle accelarator that CERN is going to power up next year is very important for us to study the nature of black holes. (for more information see my other blog), So the reason this is important is because in 2000 we found conclusive evidence that there are renegade black holes out there, well before we believed that they were fairly stationary but now we now some are in motion. So this raises the question, how did they get their velocity? Well i believe that they got their velocity much like some asteroids do in our solar system, they are captured by Jupiter's gravitional force and then escape causing a sort of slingshot effect which gives them the velocity needed to espace Jupiter's gravity. Therefore i believe that the black holes were given their velocity by a massive star or planet whose gravitional force sent them on their way or perhaps a star already in motion that simply collapsed. Well can a black hole swallow us up? Absolutely, our whole solar system for that matter. But highly unlikely. We also believe that the closer we get to a black hole the slower time becomes. So that raises the question. If a black hole comes zooming toward us, the closer it gets to us will it seemingly slow down? I belive so, even though its at the same velocity it will seem forever before it swallows us up. So this raises the question When CERN powers up for the particle accelerator and creates mini black holes, will time slow down for them and it be forever before we find out their conclusions? send me your comments.
