Given the discussion raised by Stephen Hawking’s latest book, some of our readers might find this reply, posted by Professor Edgar Andrews on an Amazon.co.uk discussion thread, useful:
“Nobody made evolution. It arises as a natural and inescapable consequence of the laws of nature in the universe in which we find ourselves, which themselves are a natural and inescapable consequence of the completely random quantum fluctuation which caused the big bang, at which point the “laws” of causality break down so it is meaningless to enquire who or what caused that.”
“But that really doesn’t wash, does it? In the same breath you say the big bang was caused by quantum fluctuations and then claim that it is meaningless to enquire what caused the big bang. That may be post-modernism but it certainly isn’t logic (or physics for that matter). But there are deeper fallacies with your explanations, as follows:
1) The laws of nature, you say, are the “inescapable consequences” of “completely random quantum fluctuations”. By what logic can inescapable consequences arise from random events? Random events can only lead to contingent consequences but to be “inescapable” the consequences cannot be contingent but must be determinate (necessary).
2) For the laws of nature to be a “consequence” of anything, the principle of causality must operate. Without causality there can be neither causes nor consequences. But you then tell us that back beyond the big bang the laws of causality break down. You really cannot have it both ways.
3) You say the big bang was “caused” by “random quantum fluctuations”. Quite apart from reinforcing my last point by invoking causality prior to the existence of the cosmos, you have to answer a different question … fluctuations in what? Before the big bang there existed neither matter, energy, space nor time, so by definition there could be no fluctuations in any of these entities. (If you claim there was something of a material nature “there” before the big bang, we are no longer talking about the ultimate origin of the universe).
3) Next comes another question. Are not quantum fluctuations themselves a manifestation of natural law (e.g. the laws of quantum mechanics)? How then could quantum fluctuations be the ultimate cause of natural law as you claim? Did the laws governing quantum fluctuation invent themselves? Not even Stephen Hawking believes that.”
