this wired review pulls no punches, and their "purchase here" link goes to the Trans Lifeline donation page. A fine idea, i I do say so myself!

On Cosmological Low Entropy After the Big Bang: Universal Expansion and Nucleosynthesis
We investigate the sensitivity of a universe's nuclear entropy after Big Bang nucleosynthesis (BBN) to variations in both the baryon-to-photon ratio and the temporal evolution of cosmological expansion. Specifically, we construct counterfactual cosmologies to quantify the degree by which these two parameters must vary from those in our Universe before we observe a substantial change in the degree of fusion, and thus nuclear entropy, during BBN. We find that, while the post-BBN nuclear entropy is indeed linked to baryogenesis and the Universe's expansion history, the requirement of leftover light elements does not place strong constraints on the properties of these two cosmological processes.
Spencer Hughes@film_girl I would really encourage people with the means to do so to check out Mastodon’s Patreon. Whenever the service is unreliable, I’m reminded that voluntary contributions are the only reason the service is running at all. I have to imagine that keeping mastodon.social online right now takes a very powerful generator burning money 24h/day.
