The plan was to immediately implement Cosmic Microwave Background (CMB) constraints to provide a physical basis for the very early universe.</p> <p>Before deploying those constraints, I made one small adjustment. To stitch them together with the existing EFE-sampled spacetime, I needed to expand the time sampling from $t=-3.9$ to $t=-3.99$.</p>
