E-book What Caused the Big Bang?
Greek philosophers assumed that the world, the universe, the cosmos, or nature as a whole, existed in some form from eternity, that is, infinitely into the past, and that the basic stuff of the universe is uncreated, everlasting, self-sufficient, and indestructible. The official Christian view, by contrast, was and is that the world was created by God out ofnothing (ex nihi/o) at some point in the finite past. Naturalistic cosmologists through the centuries have sided with the Greek view and affirmed the everlasting self-existence and self-sufficiency of nature as a whole. Traditionally, each view was affirmed solely as a matter of dogma and blind faith, though Naturalists consistently intimated that science confirms their metaphysics. Up to the present century, however, no convincing evidence was available to resolve the dispute. Has this now changed? In the twentieth century, cosmology tried to become a science, something more than mere speculation and dogma; and up to a point it succeeded. Twenti-eth-century cosmologists produced a plethora of astonishing discoveries about the universe as a whole.1 The most amazing is that the world of nature as we know it came into being at a definite point in the finite past. Our universe has not existed forever after all; it was created between 8 and 20 billion years ago. Do not conclude too hastily that God created it. or even that the origin of the world had a cause. Controversies about what, if anything, caused the Big Bang constitute the main subject matter of this book. We cannot address our central concern-What caused the Big Bang?-until we first survey evidence for the Big Bang and this theory's story of the evolution of the universe. Later, some significant challenges to Big Bang Cosmology will be confronted.
