  The primary ingredients of reality are the universal quantum fields, which
fluctuate persistently, spontaneously, and randomly. The general perception of
the scientific community is that these quantum fluctuations are due to the
uncertainty principle. Here, we present cogent arguments to show that the
uncertainty principle is a consequence of the quantum fluctuations, but not
their cause. This poses a conspicuous enigma as to how the universal fields
remain immutable with an expectation value so accurate that it leads to
experimental results, which are precise to one part in a trillion. We discuss
some reasonable possibilities in the absence of a satisfactory solution to this
enigma.
