Where have the neutrinos gone?

I feel there is a knowledge gap between understanding the interactions of particles and assessing their results aggregated over billions of years. In summary, thanks to the great minds that have built the standard model of particles (so many, including Poincare, Bohr, Planck, Dirac, Gell-Mann, Noether, Higgs, Yang-Mills)  and have mapped their interactions (Richard Feynman), we have a great understanding of what it takes to create or destroy such and such particles. What we have not really focused on is the cumulative effect of these interactions since the Big Bang. For example, we know that the decay of the neutron creates an electron, a proton and an anti-neutrino, that the sun spits out  a lot of neutrinos when creating helium, that the majority of neutrinos were probably created at Big Bang, etc. But, we have not really quantified how many have been created in aggregate, how many have been reabsorbed, how much energy is contained in aggregate by neutrinos, where that energy is likely located, i.e. regularly throughout space as they travel at light speed, or disproportionately at the periphery, as other particles travel less far. The same question can be said of electrons, which have not yet been reduced to smaller sub particles and remain “fundamental” particles.  Dark energy accounts for 75% of all energy, and remains a big mystery. All kinds of speculation have been made on its composition, from neutrinos to WIMPS to cords etc. It seems to me that “integrating” the net historical flow of known particles into quantitative models could substantially improve our understanding of energy distribution in the universe. Biology made a gigantic progress when the dimension “History” was added to its considerations. It became clear that history had a role to play in evolution, deterioration of living organisms, etc. Why would “history” cosmology also not play a key role in the evolution of our universe, i.e. involve predictable “deteriorations” affecting our common laws of nature. We humans die because the DNA replication model is imperfect and that has been key to the evolution of our system. Why wouldn’t there be as well glitches in the functioning of the universe: for example, black holes fundamentally capture a chunk of energy and make it die because it appears to be frozen for billions of years. We maintain our principle of energy conservation in spite of black holes by including the dead energy in black holes or filling the missing energy with additional dark energy. But black holes are core processes of the universe, they “kill” everything they touch. They have consequences on the universe operating system and its evolution.
