Origin Of The Universe
Origin of the Universe - What's the Latest Theory?
When it comes to the origin of the universe, the "Big Bang Theory" and its related Inflation Universe Theories (IUTs) are today's dominant scientific conjectures. According to these interrelated notions, the universe was created between 13 and 20 billion years ago from the random, cosmic explosion (or expansion) of a subatomic ball that hurled space, time, matter and energy in all directions. Everything - the whole universe -- came from an initial speck of infinite density (also known as a "singularity"). This speck (existing outside of space and time) appeared from no where, for no reason, only to explode (start expanding) all of a sudden. Over a period of approximately 10 billion years, this newly created space, time, matter and energy evolved into remarkably-designed and fully-functional stars, galaxies and planets, including our earth.
Here's what the experts are saying about the origin of the universe:
NASA: "The universe was created sometime between 10 billion and 20 billion years ago from a cosmic explosion that hurled matter and in all directions."

UC Berkeley: "The big bang theory states that at some time in the distant past there was nothing. A process known as vacuum fluctuation created what astrophysicists call a singularity. From that singularity, which was about the size of a dime, our Universe was born."

University of Michigan: "About 15 billion years ago a tremendous explosion started the expansion of the universe. This explosion is known as the Big Bang. At the point of this event all of the matter and energy of space was contained at one point. What existed prior to this event is completely unknown and is a matter of pure speculation. This occurrence was not a conventional explosion but rather an event filling all of space with all of the particles of the embryonic universe rushing away from each other."

PBS: There was an "initial explosion" of a "primordial atom which had contained all the matter in the universe."

American Association for the Advancement of Science: "In the last fifty years a great deal of evidence has accumulated in support of a "consensus" theory of the evolution of the universe. The theory holds that a "big bang" precipitated a huge split-second inflation of the universe, followed by a gradual expansion that continues to this day and is now accelerating."
