Degeneracy Pressure

Degeneracy pressure is a special kind of push that comes from quantum physics. It happens when tiny particles like electrons or neutrons are packed so closely together that they have no more room to move into. Since no two of these particles can share the exact same “space” or state, they push back when squeezed — creating a pressure that stops them from being crushed any further.

When stars die, they don’t all go out in a blaze of glory. Some fade away — quietly, beautifully — leaving behind a glowing core that tells the story of…

The Pauli Exclusion Principle

Atoms are made up of a nucleus (protons and neutrons) surrounded by electrons. These electrons don’t just float randomly — they live in specific “zones” called orbitals, like seats in a theater. Each seat (orbital) can hold two electrons, but only if they spin in opposite directions. Once that seat is filled, no other electron can sit there — it has to find another orbital or energy level. That’s Pauli’s rule.

Wave Function (Ψ)

The wave function is a mathematical function — a set of numbers you can calculate — that tells us everything possible about a quantum system. Here’s the key: Ψ itself doesn’t directly give us a physical answer. Instead, when you take its absolute square (|Ψ|²), you get the probability of finding the particle at a particular place or in a particular state.
