The Big Bang Event is the general term applied to the group of naturalistic (non-supernatural) theories which attempt to explain the origin and subsequent development of the physical cosmos by academic cosmologists.
Technically there was no medium through which sound could travel so there was no “bang”; it was actually The Big Flash Event.
“In the beginning God created the heavens” (14 billion BC [14,000,000,000] years ago) “and the earth” (4.5 billion BC [4,500,000,000 years ago])!.
The Important, yet Inexplicable Precondition Problem: Essentially all naturalistic, secular scientists agree that “in the beginning” all the matter of the future cosmos was concentrated in a single point in space and at an energy density level which was essentially infinitely dense. How that condition could possibly have happened as a result of natural phenomenon, is utterly inexplicable by any of the known characteristics of physical matter and energy. That is a rigid fact, an inescapable truth.
However let us “beg the question” and say it was without invoking either ridiculously pretend Alice in Wonderland conditions of physics that don’t exist in any known reality or invoking the divine providence as an explanation of those conditions.
Given that the inexplicable precondition did exist, the narratives of these theories all describe how the universe expanded from an initial state of incredibly high energy density and temperature. That is to say, a state of pure energy so concentrated that there was no physical matter whatsoever, not even subatomic particles).
This hyper-concentrated state of pure energy then rapidly expanded and the extreme energy density lessened and as it did it cooled and subatomic particles formed (condensed) out of the expanding and cooling energy concentration which then became the initial components of physical matter. The subatomic particles coalesced into atoms which in turn reacted to form molecules, and thus the building blocks of the physical universe began to appear.
These primordial elements, mostly hydrogen, with some helium and lithium, began to coalesce as a result of gravitational forces. Much later that coalesced matter began to form first dust clouds, and then eventually to form early stars and galaxies.
The gravitational effect of dark matter surrounding the galaxies of the cosmos is observed by astrophysicists. Most of the gravitational potential in the universe seems to be in the form of this dark matter.
The various cosmological models of the “big bang” propose to explain the evolution of the observable universe from the earliest known periods through to its subsequent phase of the large-scale formation of “clouds” of matter further coalescing. These models offer a comprehensive explanation for a broad range of observed phenomena, including the abundance of light elements, the cosmic microwave background radiation (CMB), and the large-scale structural properties of the current cosmos.
Crucially, these models are compatible with the Hubble–Lemaître law, the observation that the farther away a galaxy is, the faster it is moving away from the Earth. Extrapolating this cosmic expansion backwards in time using the known laws of physics, the models describe an increasingly concentrated cosmos preceded by a singularity in which space and time lose meaning, typically named “The Big Bang Singularity.” This “singularity” is the prevailing non-supernatural, secular, academic description of the fact that the initial incomprehensibly dense concentrate of energy which caused the big “bang” to occur CANNOT be explained by any imaginable physical theory of matter and energy.
A wide range of empirical evidence strongly favors occurrence of the Big Bang event, which is now essentially universally accepted by scientists and most others. Detailed measurements of the expansion rate of the universe place the date of the Big Bang Singularity (the creation or origin of the cosmos) at an estimated 13.787±0.020 billion years ago, which is the age of the universe.
The big bang is a reasonable and most likely factual description of the divine creation sequence of the Cosmos.
What is, in my opinion, truly remarkable is how similar it is to the biblical description of God divinely creating the cosmos given in the Book of Genesis, which was written more than 3,000 years ago.
If one doesn’t get too hung up on “the petty narrative details” of the ancient text, the Genesis account sounds like a narrative which the divine creator God might reasonably have used to explain His creation event to an, as yet, scientifically unsophisticated, agrarian tribal people. God “spoke” creation into existence, and he did so sequentially over a period of six “days.” The Hebrew which is routinely translated as day also means six periods or six epochs.
No other extant ancient creation myth gets anywhere near this close to describing the events modern science has deduced about the creation/origin of the cosmos. If one is not a biblical literalist (i.e., a fundamentalist), then there is no significant conflict between the Biblical and the secular naturalistic descriptions of the origin of the cosmos. The ancient narrative account sounds remarkably similar to the modern secular account of the origin of the cosmos.
