WebbIt also includes more parameters than physicists would like. Gravity does not fit completely. And the standard model offers no explanation for the dark matter and dark energy that seem to make up most of the universe, nor for how a matter universe could result from the nearly symmetric creation of matter and antimatter in the Big Bang. WebbFör 1 dag sedan · The standard model of cosmology tells the story of the evolution of the Universe. But contradictions suggest the story isn't quite right.

Over time physicists have developed more... Webbstandard model. While it is fair to say that the evidence for generalizing the standard model is most compelling in this domain, our knowledge of both the cosmological scenario before nucleosynthesis and of the late matter abundances in the universe are too nebulous to convincingly demonstrate the necessity of physics beyond the standard model. high current dc connectors

Over the years, numerous simulations of ΛCDM and observations of our universe have been made that challenge the validity of the ΛCDM model, to the point where some cosmologists now believe that the ΛCDM model may be superseded by another standard cosmological model. Extensive searches for dark matter particles have so far shown no well-agreed detection; the dark energy may be almost impossible to detect in a laboratory, and its value is unnaturally small com… high current delivery speakers
