X-ray/Radio Measurements Affirm Distant Cosmic Expansion Value

Recent X-ray and radio measurements of distant galaxy clusters buttress RTB’s cosmic creation model by confirming the value of the Hubble constant—which measures the expansion rate of the universe. Previous measurements of the Hubble constant using the Hubble Space Telescope (HST) to observe Cepheid variables gave the value in the nearby universe. A team of astronomers used X-ray and radio observations to prove the expansion rate of the universe at much greater distances by measuring how the cosmic microwave background radiation (the radiation left over from the universe’s beginning) changes as it passes through distant, dense clusters of galaxies. The resulting value of the Hubble constant in the distant universe agrees with the value determined by the HST using Cepheid variables. One characteristic of a good scientific model is that future experiments confirm past results. This discovery illustrates that RTB’s cosmic creation model demonstrates this characteristic.
