Evolution
Connection spreads life, but separation often sharpens it. When populations are cut off from one another, evolution calls that vicariance. It’s the start of running separate experiments. Over deep time, distance becomes difference.

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.
Big Bang
The Expanding Universe
Observation before speculation.
The Big Bang is not an explosion in space, but the expansion of space itself. Galaxies recede, light stretches, and the cosmic microwave background preserves a faint afterglow of an early, hotter state. This section focuses on what we can measure — redshift, background radiation, large-scale structure — and how these observations map the universe’s growth over billions of years.

We do not know the ultimate fate of the universe, but the leading ideas are that it expands forever, collapses and starts over, or ends in something more extreme.

ΛCDM remains the leading cosmological model because our current best measurements indicate gravity is not strong enough to stop the universe’s expansion.
