“an­ti­quarks? Why are there not equal num­bers of each? It is cer­tain­ly for­tu­nate for us that the num­bers are un­equal be ear­ly uni­verse and left a uni­verse filled with ra­di­ation but hard­ly any mat­ter. There would then have been no galax­ies, stars, or plan­ets on which hu­man life could have de­vel­oped.” — Stephen Hawking
