In light of present knowledge, his reflections were largely correct, and the gap in his cosmic history—the interval from dynamic extension to material particles—remains subject to debate today. Cosmologists are not unanimous on what happened in this period.  Nonetheless, they have substantiated that force came first and that material chaos followed next. The universe did start dynamically as a singularity, whose first outward-bound and energetic action—the Big Bang—wove a dimensional structure in its wake. The continuum (the disentangling of space and time) emerged 10−51 years and the chaos (the formation of atomic nuclei) 10−5 years after the Big Bang—followed by the creation of atoms, of stars, the Sun, and the Earth. Within the expanding bubble of the Bang is the universe today.
