Todd Stashwick No From Chicago Shirt

The universe expands from an unimaginably hot and Todd Stashwick No From Chicago Shirt speck (perhaps a singularity) with all the known forces unified. In a tiny fraction of a second tremendous changes are unleased. The strong force separates from the electronuclear. The weak force then separates from the electromagnetic. ~1 microsecond into this process Quarks are confined within hadrons. 1 millisecond in hydrogen nuclei are formed. 1 second in neutrinos begin to interact with other particles. At about the 3 minute mark helium nuclei are formed. 379,000 years in, the plasma cools enough for stable atoms to form and photons are released from this veil forming the Cosmic Background Radiation we see today. It’s 100 million years before the first stars can form, many generations of stars are busy creating the heavy elements necessary for life as we know it from the process of fission (both during the life of the star and during nova, supernova, and stellar collisions including those of neutron stars). All of these things almost certainly had to happen before life could form. So that’s somewhere around 1 billion years later before there is likely to be a place that is hospitable to life as we know it. But that’s even before galaxies have formed so that may be way too early, we just don’t know for certain.
