The cyclic model of the universe he helped pioneer is just that: a theory that the universe forms itself again and again in cycles. Proponents of this model are asking us to rethink the Big Bang and the rapid inflation of the universe. They contend that doing so could fill in some of the biggest gaps in our common understanding of the way space Science does not have a conclusive answer yet, but at least two potentially testable theories plausibly hold that the universe—and therefore time—existed well before the big bang. Scientific American is the essential guide to the most awe-inspiring advances in science and The Founder of Cosmic Inflation Theory on Cosmology's Next Big Ideas for the big bang—like a 3. Heat and density play big parts. Humason and Hubble also believed that the origins of the universe were much hotter and much denser, too. This would lend towards a theory that would presume an explosion of sorts took place to disperse galaxies and bodies across space. This is the very basis of the Big Bang theory. 4. Scientific American astronomy editor George Musser explains.. This question really has two parts. First, how was matter able to get out of the big-bang singularity? After all, physicists describe Theory and hypothesis may be synonyms in everyday language, but in scientific language they are not. The big bang theory is not an hypothesis, as you are suggesting. In general a theory is a set of laws verified through experiment and observations, far from a simple guess. .
