Black Hole Mystery Solved

WHAT ARE BLACK HOLES?
As most of you are aware BLACK HOLE is a region of space in which the gravitational field is so powerful that nothing, not even electromagnetic radiation can escape from it. Dur to this black holes can not be seen (as they absorbs light radiations) but can only be experienced by their ultra strong gravitational pull. That's why they are named as BLACK HOLE.. They continue to grow in size by absorbing any matter that comes in range of their gravitational field.
HOW MUCH THEY CAN GROW?
Till now it was not sure that what can be maximum size of a black hole. These black holes are now known to exist throughout the Universe and the largest and most massive are at the centers of the largest galaxies. These "ultra-massive" black holes have reported to have mass about One Billion Times that of our own Sun.
