[Date Answered] November 4, 2008 [Questioner (age, location)] Emily (texas) [Answer] Extracted from our web page Black Holes: Black Holes are theoretical objects. A black hole is an object which has such high gravitational pull that not even light can escape. Hence it is black. Which makes it pretty hard to observe directly. Black Holes may form as the result of the collapse of a very massive star at its death. What would it be like to enter a black hole? Not pleasant. First, as you approach the black hole the difference in the gravitaional pull on your head compared to your feet (known as tidal forces) would rip you apart. But suppose you survived that. Once you cross the event horizon there is no turning back. Then the only thing to do is avoid the black hole itself at all costs. If you run into that singularity it will crush your body right out of existence. [Question] 
What happens after wew get into a black hole, how do we know there is a black hole in side of every sprial and elpitical galaxy if we cant go near one because we would get sucked in?
