The other three naturalistic explanations that attempt to make sense of the sheer unlikelihood that a life-permitting universe would come about spontaneously (without being designed by an intelligent being) postulate that countless universes--a multiverse --exist and that the extremely large number of universes makes it likely that a life-friendly universe would come about.

In recent years this scenario has repeated itself in the theoretical realm, as physicists now speak seriously about parallel universes, rendering the one that humans inhabit just one of countless (literally) others.
Lemaitre used Einstein's equations to prove that the Universe had a beginning where all matter and energy were compressed into a single compact particle which he called a "primeval atom".
If the recent difficulties of theoretical physics arose from flaws in scientific culture and institutions, rather than from the sheer abstruseness of natural laws, our progress in understanding the universe just might resume.
Of course, each one of us has to find our own answers to these primary questions, for no man can carry the burden of another and no amount of rational persuasion can lead to that gnosis which yields certainty in the heart, but at such moments of truth we can at least be sure of one thing: the reductive explanations of scientism are no longer adequate to deal with the most fundamental questions about the universe and the human condition.
Scientists called this something "dark energy" and suggested that it supplies a repulsive force that causes the universe to expand outward with increasing speed.
