What is the Big Bang Theory and how does it account for the creation of the universe?

Question

Isaac Abel · Accepted Answer

the theory of big bang is completely "HYPOTHETICAL"

IT IS "" ASSUMED"" that there was a small particle, a very high density state particle, that exploded, sending particles hurtling in all directions at very high speeds. The volume of the super high density increased steadily while the mass stayed constant. Over time, the dispersed mass cooled and slowed down, giving rise to planets, stars, galaxies, and other celestial bodies.

This is Theoretical because it has been tested and found to be true; it is not factual, but it does indicate that it is far more likely to be the truth than something that is Hypothetical. It is not Hypothetical, which is just an educated guess.

The ratios of hydrogen to other "primordial" gases provide additional evidence for the Big Bang Theory, which explains how the universe expanded and accounts for the universe's creation. In addition, the Big Bang Model explains cosmic microwave radiation in space, which does not originate from existing bodies.

Since this is not my area of expertise, I normally wouldn't have responded, but to say that it's hypothetical is actually inaccurate. I'd like someone with more experience to provide a more thorough explanation.

undefined The Big Bang Theory is the prevailing cosmological model that explains the origin and evolution of the universe. According to this theory, the universe began as a singularity, a point of infinite density and temperature, approximately 13.8 billion years ago. At the moment of the Big Bang, the universe rapidly expanded and began cooling, eventually leading to the formation of matter and energy. As the universe continued to expand and cool, subatomic particles formed, which eventually led to the formation of atoms, stars, galaxies, and the complex structures observed in the universe today. The Big Bang Theory accounts for the creation of the universe by describing how all matter, energy, space, and time originated from a single point, undergoing a process of expansion and evolution over billions of years.
