Pls boost!
🚨 So @spreadmastodon and everyone that has just done or encouraged a #TwitterMigration or the past #joinmastodonday: 🚨
Grassroots folks are organizing our next push to get Twitter folks to make the jump to #Mastodon in the first weeks of May!
This campaign is called #Maystodon - & if you still have a Twitter account and want to help:

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.
