Evidence for Dark Energy Driven by Star Formation: Information Dark Energy?

Evidence is presented for dark energy resulting directly from star formation. A survey of stellar mass density measurements, SMD(a), as a function of universe scale size a, was found to be described by a simple CPL w0 - wa parameterisation that was in good agreement with the dark energy results of Planck 2018, Pantheon+ 2022, the Dark Energy Survey 2024, and the Dark Energy Spectroscopic Instrument 2024. The best-fit CPL values found were w0 = -0.90 and wa = -1.49 for SMD(a), and w0 = -0.94 and wa = -0.76 for SMD(a)0.5, corresponding with, respectively, good and very good agreement with all dark energy results. The preference for SMD(a)0.5 suggests that it is the temperature of astrophysical objects that determines the dark energy density. The equivalent energy of the information/entropy of gas and plasma heated by star and structure formations is proportional to temperature, and is then a possible candidate for such a dark energy source. Information dark energy is also capable of resolving many of the problems and tensions of Lambda CDM, including the cosmological constant problem, the cosmological coincidence problem, and the H0 and sigma 8 tensions, and may account for some effects previously attributed to dark matter.
