“Quantum fluctuations are, at their root, completely
a-causal, in the sense that cause and effect and ordering of events in time is
not a part of how these fluctuations work. Because of this, there seem not to
be any correlations built into these kinds of fluctuations because 'law' as we
understand the term requires some kind of cause-and-effect structure to
pre-exist. Quantum fluctuations can precede physical law, but it seems that the
converse is not true. So in the big bang, the establishment of 'law' came after
the event itself, but of course even the concept of time and causality may not
have been quite the same back then as they are now.” ― Sten F. Odenwald
