Summary
A low-entropy beginning is not explained by the laws of physics themselves and therefore requires an account of why such special initial conditions obtained.
Observation / Fact
Physical laws describe how systems evolve from given conditions; they do not select those conditions. The laws permit vastly more high-entropy initial states than low-entropy ones.
Why This Is Non-Trivial
Appeals to chance or necessity fail to account for the universe’s extreme initial order. Without explanation, the arrow of time and the existence of structure remain mysterious.
What It Implies
The specificity of the universe’s initial state points beyond impersonal physical law toward a selecting cause or principle capable of setting boundary conditions.
