Chapter 01 of 5
The Coulomb Barrier
Why atoms resist fusing and the extreme pressures needed to force them together.
- Primal Limits
The Big Bang's Leftovers
After the Big Bang, the universe was 98% hydrogen and helium. It lacked the complexity required for life, planets, or solid ground.
- The Problem
Atomic Loneliness
Atoms naturally repel one another. To build heavier elements, we must force nuclei to touch, but they are guarded by invisible shields.
- Mechanism
Electrostatic Repulsion
Every atomic nucleus has a positive charge. Like two north poles of a magnet, nuclei push away from each other with incredible force.
