Origin of the Universe and the Many Worlds Hypothesis. Randall Niles reviews the two major cosmogonies: 1) Something Did It OR 2) It Did Itself.
How Does Mainstream Science Currently Explain the Origin of the Universe (Cosmos)?
First, some definitions...
Cosmos the orderly universe and everything in it.
Cosmology the study of the physical universe, including its properties, structure, and dynamics.
Cosmogony a theory about the origin of the cosmos.
The mechanics of the cosmos are observable and testable through the scientific tools of Cosmology. The origin of the cosmos is limited to forensic conjecture -- Cosmogony.
Cosmogonies are philosophical theories, not scientific theories, since the origin of the cosmos is a singular, historic event. The scientific method cant be used, because that would require duplicating, observing, and testing that one-time event. A cosmogony must be examined like any other historic event using standard rules of evidence, logic, reason, and conviction.
There are only three basic cosmogonies:
1.The cosmos is eternal its always been here.
2.The cosmos started as a random phenomenon an accidental explosion of some kind.
3.The cosmos started as a creation of a Creator a supernatural cause and designed effect.
In the decades since Einstein, observational discoveries in the areas of cosmology, astronomy, physics, and mathematics have shown beyond a reasonable doubt that our universe did, in fact, have a beginning. Science now declares that prior to a certain moment in history there was nothing; during and after that certain moment in history there was something -- our cosmos. Therefore, Cosmogony No. 1 is off the table...
What about No. 2?
The Big Bang Theory is today's dominant scientific cosmogony. According to this theory of origin, the universe was created between 13 and 20 billion years ago from the random, cosmic explosion (or expansion) of a subatomic blip that hurled space, time, matter, and energy in all directions. Everything the whole cosmos -- 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.
If you think this sounds a bit too simplistic, heres what the mainstream experts say:
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."
Jet Propulsion Laboratory, California Institute of Technology: Many cosmologists believe that the universe was created about 15 billion years ago with a cosmic explosion they nicknamed the Big Bang. This explosion produced an expanding cloud of the simplest known chemical elements: hydrogen and helium.
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."
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..."
Cosmogony No. 3 is pretty simply stated: "In the beginning [time], God created [bara -- Hebrew: created from nothing] the heavens [space] and the earth [matter]." (Genesis 1:1)
