Big Bang Hubble Contradiction Confirmed
A reason to lose your job?

Using data obtained from the Hubble Space Telescope, astronomers have confirmed a contradiction between two different estimates of the Hubble constant—an extremely important number in cosmology.
Secular scientists claim the universe is expanding as a result of a “Big Bang” 13-14 billion years ago. The inference of an expanding universe is based on the fact that the light spectra from distant galaxies have been “redshifted” to longer wavelengths. Some creation scientists think this interpretation of the redshift data is correct, while others do not. Even if the universe is expanding, this doesn’t necessarily demand a Big Bang explanation. One could imagine scenarios in which God, for some reason, imposed an expansion on his created universe, i.e., to prevent gravitational collapse. Of course, if redshifts are indeed caused by something other than cosmological expansion, creation scientists will need to provide an alternative explanation for those redshifts. In fact, creation scientists have already proposed alternate explanations, although they are still tentative at this point.
The expansion rate is characterized by a figure called the Hubble parameter, also known as the Hubble constant, indicated by the symbol H0. This number has units of speed per units of distance, namely kilometers per second per megaparsec—km/sec per mpc—a megaparsec is 3.26 million light years. This means that the speed at which a galaxy is thought to be moving away from us depends on the galaxy’s distance from us. The farther away the galaxy, the faster it’s receding…
