text: Firstly, the force of gravitation would be so great that light would be unable to escape from it, the rays falling back to the star like a stone to the earth.
text: The term ‘black hole’ is one used by space scientists to describe places in space where the force of gravity is so great that all matter in a region is squeezed into tiny spaces, to the extent that even light cannot travel!
text: If the Earth were compacted so that it had the same mass, but half its present radius, the force of gravity at its surface would be four times as great as it is now; if it were compacted further, a density would eventually be reached at which its constituent subatomic particles would be unable to support their own weight and would collapse to a state of (theoretically) infinite density, producing a black hole.
