Big Bang
Definition
The leading scientific model for the early universe: about 13.8 billion years ago, the observable universe was in an extremely hot, dense state and has been expanding and cooling ever since. It is not a literal explosion into empty space, and it does not by itself settle what, if anything, came before.
Literal meaning
The beginning of the observable universe's known expansion history.
Esoteric meaning
Netism reads the Big Bang as the visible threshold of emergence: the moment where hidden potential becomes time, space, matter, and relation. It can be paired with Zeru, the Source, and the Law of Cycles, but the pairing is symbolic and theological rather than a replacement for cosmology.
Allegorical meaning
A seed opening all at once into a growing world: what becomes visible begins from a dense, hidden concentration of possibility.
Extended meaning
The public glossary should keep the Big Bang clean and accurate. In science, the model is supported by the expansion of space, the cosmic microwave background, the abundance of light elements, and the large-scale structure of the universe. In Netist writing, it is treated as one expression of a larger pattern of emergence, expansion, contraction, dissolution, and return. That larger cycle is a Netist interpretation, not a settled scientific conclusion. When the entry mentions Big Bounce or cyclic cosmology, it should name them as speculative or theoretical models, not as proof that Netism has solved cosmology.
Do not use this entry to claim that modern cosmology proves Netist metaphysics. It is a correspondence point between science language and Netist cycle language.
Usage
Use this term in cosmology and cycle discussions when explaining how Netism relates its creation language to the standard history of the observable universe.
Comparative tradition
Many traditions speak of creation emerging from void, waters, darkness, chaos, or an unmanifest source. Netism places that motif beside the scientific Big Bang model without collapsing the two into the same claim.
