The End of Cosmology.

The quickening expansion of the Universe will eventually pull galaxies apart faster than light, causing them to drop out of view.

This process eliminates reference points for measuring expansion and dilutes the distinctive products of the big bang to nothingness. In short, it erases all the signs that a big bang ever occurred.

No way to ever truly know the Origin...

Therefore it remains THEORY and conjecture.

and who the HELL are you tell me what I know or don't know

Theory vs. Hypothesis vs. Law

There is no LAW of Evolution...and certainly not Big Bang.
