Good article...I was always skeptical about the missing dark matter and energy concept.

Now can you explain why there are 2 conflicting measurements of the Hubble Constant (one using Cepheid variables and distant Supernova red shift-about 74 km/sec/megaparsec, the other using a Big Bang timeline and date from the Planck Space Mission-67.4 km/sec/megaparsec)

Apparently if the density of the universe (now assumed to be uniform) is NOT uniform, this accounts for the difference (of course there could also be errors in measurement, but this difference has stood for years, despite observational improvements). Its an important difference since the higher value implies an accelerated expansion (and supports the missing dark E & M) while the lower value a younger and perhaps pulsating universe?
