Ultimate physical origin of ΛCDM cosmology

Ascertain the physical mechanism underlying the initial singularity and the origin of ΛCDM cosmology in the absence of a complete quantum gravity theory, including how the Universe’s mass-energy content emerges at t=0 consistent with conservation laws and subsequent Friedmann evolution.

Background

While proposing a new temporal-singularity framework, the paper also reflects on the foundational status of standard ΛCDM, which itself presumes an initial temporal singularity at the Big Bang. In the absence of a robust quantum gravity theory, the author emphasizes that the physical origin of ΛCDM’s initial conditions is likewise unknown.

This underscores a broader foundational question: the mechanism of cosmogenesis and the emergence of the initial mass-energy content consistent with general relativity and observational cosmology.

References

Moreover, the ideas presented in this paper are not any more presumptuous standard $\Lambda$CDM, which predicates on the temporal singularity of the Big Bang as the moment of creation, so one must also acknowledge that the ultimate physical origin of $\Lambda$CDM cosmology is, ahead of the availability of a robust quantum gravity theory, likewise unknown.
