How much (in meters) is a black hole's diameter? Where do you go if you were to be sucked down a black hole? What would happen to you?

The diameter of a black hole depends on the mass of the original object that becomes a black hole. So the more massive the object, the bigger the diameter of a black hole formed from that object.
If earth became a black hole it would have a diameter of about 0.017 meters, about the size of a marble! Think of how small your bedroom would seem then! Our sun would have a diameter of about 6000 meters, just a little less than 4 miles.
No one really knows what would happen if you were to get sucked into a black hole. The problem is that once you are inside the black hole there is no way to talk to the people outside the black hole. So, we don't know what goes on inside a black hole.
A possibility is that you would slowly be stretched out like a string of spaghetti until you snapped! So stay far away from the edges of black holes!
