Since we're hung up on terminology, black holes don't suck, just like the Earth doesn't suck you in. You fall in to black holes, just like the Earth makes you fall, since they're both using gravity.


...unless you pay them.

They accrete matter.

We haven't fallen into the black hole at the center of our galaxy just like we haven't been forced into the sun we orbit in this solar system. But if just one black hole the size of a quarter were to fall into the Earth as a result of this how long would it take until monumental change would occur on its surface, its orbit, its density and gravity, tidal changes, ect. That's just if one small one was created, and who's to say it wouldn't grow over time to becomes a much more serious threat.

All hail Jacko Master Physicist!
