INTRODUCTION

English translation pending.

CORE DEFINITION

Quantum field theory treats the vacuum as filled with zero-point energy and, summing over all field modes, predicts a vacuum energy density roughly 10^120 times larger than the cosmological constant measured from cosmic expansion. This is often called the worst prediction in physics. The gap shows that quantum mechanics and general relativity have not yet been reconciled, and it warns against transferring results across scales without checking magnitude.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Check the scale: estimate the orders of magnitude before moving a law from one domain to another - Pause the analogy: stop the transfer when the scales differ by many powers of ten - Seek a bridge: look for an explicit linking assumption instead of assuming the law carries over

Anchor fast decisions

Summing the zero-point energy of every field mode yields a density far larger than anything observed, while general relativity constrains the cosmological constant to a tiny value. The two frameworks thus disagree by about 120 orders of magnitude, which means the microscopic and macroscopic descriptions of the same quantity cannot both be complete as they stand.

Demographic Transition

Demographic transition refers to the phenomenon in which a country or region transitions from a pre-industrial economic system to an industrialized economic system, often accompanied by a transition from high birth and death rates to low birth and death rates. This theory was proposed by American demographer Warren Thompson in 1929, who observed and studied the changes or transitions in birth and death rates in industrialized societies over the past two centuries.
