Verified. Empirically supported and rationally deduced.
Expanding Universe
Galaxies formed early in cosmic history, within a few hundred million years of the Big Bang. This shows that structure emerged quickly from an initially simple universe. Observations confirm that gravity wasted little time turning primordial gas into organized systems, even before features we now consider typical. Such as central supermassive black holes commonly found in galaxies.

FAQ
Is the Big Bang singularity scientific or philosophical?
- Philosophers: "It’s all speculation."
- Scientists: "We’re working on it!"
Big Bang Singularity
The expansion of the universe is solid science. The singularity is not. It marks the point where our equations stop working, not where we suddenly know what “began everything.” Calling that boundary scientific certainty confuses mathematical breakdown with physical reality. Good thinking separates evidence from speculation without pretending speculation is failure.
