Is Dark Matter Trapped Dynamic-Density Dark Energy Or Ancient CMB?
by Steven Gussman The mechanism behind the present accelerated metric expansion of the universe is not yet well-understood. Most often, astrophysicists deduce that there must be a "dark" energy of a particular density associated with this expansion. This is not particularly strange until you realize that the claim is that it is a static scalar field (that is, a field whose density does not depend on its volume; shrink or stretch space and the density of dark energy remains constant). This rather obviously violates the conservation of energy (of course dark energy must indeed be created and destroyed when spacetime is expanded or contracted). Astrophysicist Ethan Siegel is forthright about this: he believes, due to the empirical expansion of the universe, that energy is not strictly conserved (and he admirably wants the mainstream to admit that this is their necessary belief as well). [1] I must confess that this never made much sense to me, and is ano
