What is the Big Bang Model of the origin of the universe?

Answer 1

The Big Bang Model expresses/visualizes the abstraction of the Inflationary model for the Universe to provide for an environment in which we can understand its dimensional boundaries. The Big Bang is more a reference to an unfolding evolutionary model of existence in which SpaceTime

allows for the integration of positive density matter. The Big Bang expresses the understanding of an evolving universe from a one dimensional singularity to the traditional fourth dimensional model of our ever-accelerating

universe. Indeed, anything outside of our traditional fourth dimensional reality is not part of our universal existence.

The big-bang

model is based on two assumptions. The first is that Albert Einstein's general theory of relativity correctly describes the gravitational interaction of all matter. The second assumption, called the cosmological principle, states that an observer's view of the universe depends neither on the direction in which he looks nor on his location. This principle applies only to the large-scale

properties of the universe, but it does imply that the universe has no edge, so that the big-bang

origin occurred not at a particular point in space but rather throughout space at the same time. These two assumptions make it possible to calculate the history of the cosmos after a certain epoch called the Planck time. Scientists have yet to determine what prevailed before Planck time.

As the considered point of origin for the Big Bang Model was the complex SpaceTime

condition of singularity, it persisted as the whole of Time and Space within a dimensional framework in which the fundamental forces were unified. Both general relativity and quantum mechanics break down in describing the pre-Big

Bang consistence, but in general, quantum mechanics does not permit particles to inhabit a space smaller than their wavelengths. Upon creation, the unification of forces within the singularity evolved/transformed towards their current fourth dimensional condition. In this way, the SpaceTime

continuum is merely the vessel of our universe. As positive density matter began to interact within our traditional fourth dimensional boundaries, it provide for the displacement of the zero density medium and allowed for the complimentary condition of negative density matter. So where the order of the universe was absent of positive density, creation has messed with its balance. Subsequently the evolution of large structures versus small structures for positive density matter is random at best, or the universe would have almost immediately collapsed in on itself. Instead it is expanding and becoming more ordered with time. Therefore there is no real center to the universe; rather there is only the unfolding of SpaceTime

into varying evolutionary conditions. It is not a center which can be viewed, or even measured, as its very reality is subject of debate. It is this persistence that purports, in our dimensional measure of being, a flow of influence to and from center. Thus the notion of a universal singularity is derived, not from its focus of centricity,

but from within its ambit of containment. It is not a fixed location in Space, but rather a fixed condition in Time. These are the conditions of our creation and termination.

Note: Everything we know about the universe is based on our ability to observe and measure varying degrees of luminosity/radiation within this fourth dimensional confinement; i.e.,

this is our known universe. Our known universe has many imposed limitations, based on our ability to observe and measure it, but no one can really estimate as to the actual age and size of the universe beyond the interpretation of empirical evidence we are able to gather and collate. As of matter of contention is whether these measures for age and size have any real meaning outside our observable universe. This is partly because the dimensional boundaries of our SpaceTime

are always evolving and ever-expanding,

per our ability to observe and measure it. Another aspect of for consideration is whether this small pocket of our observable universe is representative of the universe as a whole.
