Augustine of Hippo writes these words in reference to
the creation of the heavens and the earth: "non de
ipsa substantia dei sed ex nihilo" (Confessiones XII).
That is, God has not created the material world out of
his own substance, but rather from nothing. While I believe
that such talk of creation EX NIHILO needs to be
qualified, there is a fundamental insight contained in
Augustine's observation: God does not create the
universe from his own substance or being; the
Judeo-Christian account of creation rules out
pantheism. It thereby seems that the energy mentioned in
Einstein's famous equation is not the same "dynamic
energy" of Isa 40:26.
The energy that pervades our universe and which is
interchangeable with mass can be quantified, measured or tested.
Do we want to say that Jehovah's energy can be measured in a quantitative
manner or that it is the flip side of mass?
The equation e=mc² means that energy is equal to mass
times the speed of light squared. Of course, we know
that the speed of light (c) is 300,000 km/sec.
Brain Greene writes: "From e=mc², we know that mass
and energy are interchangeable; like dollars and
euros, they are convertible currencies (but unlike
monetary currencies, they have a fixed exchange rate,
given by the speed of light times itself, c²" (The
Fabric of the Cosmos, page 354).
