What type of model would you use to represent the big bang theory?

Answer 1

If you are asking for an opinion, then The ΛCDM or Lambda-CDM model, or Standard model, is probably the most representive of the earliest phases of the Big Bang. It supports a common model for the Universe as filled homogeneously and isotropically with an incredibly high energy density and huge temperatures and pressures (and which very rapidly cooled with its dimensional expansion). The standard model purports no physical center to the universe; rather it support a dimensional centricity for the evolutionary expansion of our SpaceTime continuum.

While the Big Bang model is well established in cosmology, it is likely to be refined in the future. While the known universe provides some glimpse about the earliest moments of the universe, the equations of classical general relativity indicate a dimensional instability (or singularity) for the origin of cosmic time. Moreover, general relativity must break down before the Universe reaches the Planck temperature, and a more accurate assessment of quantum gravity may avoid the conclusion for a singularity.

Answer 2

The best way to describe Big Bang Cosmology as a model is, "one that is supported by all available observational evidence, and contradicted by none."

Answer 3

The current model is called the ΛCDM model, or Lambda Cold Dark Matter model.
