- Scientists: "We’re working on it!"
Big Bang Singularity

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.
