‘A force stronger than gravity inside the Earth’: How magnetism trapped itself inside our planet

The image of the atom, with electrons crowded around a central nucleus bulging with protons and neutrons, is as iconic to our conception of science as the helix of DNA or the rings of Saturn. But no matter how much we scratch the surface of these scientific basics, we can go deeper than that, by focusing this microscope further and discovering more of the forces that govern our world.

In his new bookCharge: Why does gravity rule?“, theoretical physicist Frank Close explores the fundamental forces that govern our universe, asking questions along the way that seek to explain how the delicate balance of positive and negative charges paved the way for gravity to shape our universe.
