The Cosmic Powerhouse PDF explains fusion in a way that textbooks often get wrong. Inside the core, pressure is 250 billion times Earth’s atmospheric pressure. Under this force, hydrogen nuclei (protons) slam together so hard that they overcome their natural electromagnetic repulsion (the Coulomb barrier).

When CMEs hit Earth’s magnetic field, they create auroras (Northern Lights) but can also damage satellites, disrupt GPS, and trigger power grid failures.
