Cosmology Tested in the Laboratory

Laboratory measurements with superconducting rings confirm scientists’ understanding of the universe’s early development, providing additional support for RTB’s cosmic creation model. The early universe cooled very quickly, forming defects where it did not “freeze” uniformly. Theoretical descriptions of the nature and number of defects have been difficult to test because of the challenge of detecting the anomalies without disrupting the experiment. However, by heating and cooling a pair of superconducting rings, scientists cleanly measured how the presence of defects depends on the rate of cooling. The results confirmed a theoretical description that also applies to the early universe (because the universe cools as it expands). This confirmation strengthens scientists’ confidence in the big bang model (and, consequently, RTB’s cosmic creation model).
