Gas comprises over 75% of the detectable matter in the universe. As the universe supposedly expands, conventional astrophysics theory figures the gas ought to cool down. Instead, it’s getting hotter, according to the latest guesstimate.
An international team of astrophysicists used 8 maps of space built from 6 received channels at various electromagnetic frequencies. Using a variety of filtering and correlative techniques, biased by theoretical models, the researchers “obtained new constraints on the thermal history of the universe. The cosmic thermal energy content is dominated by hot gas in galaxy clusters at low redshifts and groups and protoclusters at high redshifts. Its evolution is almost entirely driven by the growth of structures as baryons get shock heated in collapsing dark matter halos.”
“As the universe evolves, gravity pulls dark matter and gas in space together into galaxies and clusters of galaxies,” hypothesizes Yi-Kuan Chiang, lead author of the study. “The drag is violent – so violent that more and more gas is shocked and heated up.”
The conjecture about cosmic thermal evolution based upon “shock” heating from “dark matter halos” is bogus, as dark matter has been disproven. Further, given that there was no direct measurement, only speculative convoluted mathematical construals, there is insufficient reason to think that the hot gas results are anything more than hot air.
The conventional cosmological model (ΛCDM) is wrong in most every way. The model presumes invisible and undetected dark matter and dark energy as dominating cosmic evolution. These dark fantasies have been disproven, but ΛCDM swears by them.
To create its simple mathematical models, ΛCDM assumes that the universe is uniform at large scales. This too has been shown untrue.
ΛCDM relies upon a mythical “Big Bang” cosmic origin ~14 billion years ago, based upon the first detected light. That can’t possibly be right, as mature supergalaxies have been found that date to less than a billion years from that supposed birth mark.
Azerbaijanian physicist Lev Landau once remarked that “Cosmologists are often wrong but never in doubt.” Modern cosmology is mostly mythology, on par with astrology in its veracity.
