Exploring the Post-Big Bang Universe: Theories and Insights

The concept of a singularity – a point of infinite density at which time and space as we know them cease to exist – was eventually dropped in the middle of the 1900s due to it being in conflict with observational data. Consequently, no theories have emerged about what transpired after this point because by that time, scientific observations of the universe began.

The Big Bang is often loosely defined as a singular event that marked the beginning of our universe. However, it is simply a descriptive term for the thermally-coldest, densest state that our universe was observed to enter approximately 13.8 billion years ago, a state that has been continually expanding and cooling ever since.

The Origins of the Universe: Beyond the Big Bang

Space and time as we understand them did not come into existence with the Big Bang. In fact, space was there before the Big Bang, and it was within this existing space that the proto-universe's expansion allowed for the cooling necessary to form protons, neutrons, and gravity, followed by the formation of atoms, primarily hydrogen, helium, and some lithium.

Time is much more abstract. It did not arise with the Big Bang but is a concept human beings invented to rationalize change and development. Change and development are natural processes that occur independently of time in a cyclic manner, influenced by the initial expansion and subsequent interactions in the universe.

The Concept of Infiniteness in the Universe

The universe is a continuous entity, infinitely large and enduring in space and time. Scientific understanding supports the fact that the universe has always existed, and that space, time, and matter-energy have always been present and thus were neither created nor caused by a god or an external entity.

Space is defined as an infinite volume with no surface, and time is considered infinite when seen from the perspective of the universe's infinite duration. The universe's composition – including space, time, and matter-energy – supports the conclusion that the universe is an eternal and self-explanatory entity, devoid of any need for a creator.

The Existence of Gods in the Universe

Gods in the traditional sense are conceptualized as beings with greater knowledge than humans, greater capabilities, and minds with desires and fears. In the context of the universe, the Big Bang did not represent a creation but rather a phase in the universe's evolution. This implies that creator-gods, as traditionally conceived, never existed.

Non-creator gods might exist, but their existence would need to be proven through observable evidence, which currently does not exist. Accepting the non-existence of creator gods logically follows from the understanding that the universe is self-explanatory in its infinite nature.

Conclusion

The universe, understood as an infinitely large and enduring entity composed of space, time, and matter-energy, does not require a creator. Theories of the Big Bang serve as a descriptive model of a dense, cold phase in the universe's history, but they do not imply the creation of the universe. Instead, they align with the notion that the universe has always existed, evolving according to natural laws without the need for supernatural intervention.

Key Takeaways: The Big Bang is a descriptive term for a phase in the universe's evolution, not a creation event. Space is an infinite and timeless entity preceding and existing beyond the Big Bang. Humans invented time to understand change, but in the universe, change occurs without the need for time. The universe's eternal existence and self-explanatory nature make the concept of creator gods unnecessary.
