"Science had long predicted that if a sufficiently large star collapsed at the end of its life, all the matter left in the star would be crushed into an infinitely small point with infinite gravity and infinite density -- a singularity. Hawking realised that the Universe was, in effect, a black hole in reverse.
Instead of matter being crushed into a singularity, the Universe began when a singularity expanded to form everything we see around us today, from stars to planets to people. Hawking realised that to come to a complete understanding of the Universe he would have to unravel the mysteries of the black hole."Tags: singularity big bang physics science space time universe multiverse gravity light radiation |
