QUOTES ABOUT THE BIG BANG
FRED HOYLE: "The stakes are high, and win or lose, worth playing for." [Hoyle coined the term Big Bang]
ALBERT EINSTEIN: "For every one billion particles of antimatter there were one billion and one particles of matter. And when the mutual annihilation was complete, one billionth remained - and that's our present universe."
BILL BRYSON: "Tune your television to any channel it doesn't receive, and about 1 percent of the dancing static you see is accounted for by this ancient remnant of the Big Bang. The next time you complain that there is nothing on, remember that you can always watch the birth of the universe."
PAUL DAVIES: "A universe that came from nothing in the big bang will disappear into nothing at the big crunch. Its glorious few zillion years of existence not even a memory."
