Appeals Quote by Fred Hoyle
“On scientific grounds this big bang assumption is much less the palatable of the two. For it is an irrational process that cannot be described in scientific terms. . . . On philosophical grounds too I cannot see any good reason for preferring the big bang idea. Indeed it seems to me in the philosophical sense to be a distinctly unsatisfactory notion, since it puts the basic assumption out of sight where it can never be challenged by a direct appeal to observation.”
