🧊 The Pauli Exclusion Principle: Why Matter Takes Up Space

This simulator visualizes how identical fermions fill up available quantum states one at a time while bosons can pile freely into the lowest state, and how that same exclusion mechanism generates a real, measurable degeneracy pressure as particles are compressed.

🔬 What It Demonstrates

This simulator visualizes how identical fermions fill up available quantum states one at a time while bosons can pile freely into the lowest state, and how that same exclusion mechanism generates a real, measurable degeneracy pressure as particles are compressed.

🎮 How to Use

Toggle between fermion and boson particle types to watch how they fill energy levels differently, then increase the compression or particle count to see degeneracy pressure build up and resist further squeezing.

💡 Did You Know?

The electron degeneracy pressure holding up a white dwarf is so purely quantum mechanical that it would still exist even if the star were cooled to absolute zero, with no thermal motion left at all.
