Black Hole Facts
A black hole can be defined as a densely packed matter so that nothing can escape from there. Not even light can escape. This space has a huge gravity pull. As the name implies, a black hole is entirely black. It cannot be sensed directly by using any type of instruments or electromagnetic radiation. Probably the Milky Way also has a huge super massive black hole in its middle but our planet is not in any danger of getting swallowed.
