For centuries, scientists clung to the belief that planets moved in perfect circles. It took over 600 nested circles—epicycles—and the revolutionary insight of Johannes Kepler to reveal the truth: planetary orbits are ellipses. This long struggle against ingrained assumptions mirrors the challenges faced by modern theoretical physics, particularly string theory.
"String theory is the new epicycles," argues Prof. Ivette Fuentes in a recent podcast with Theories of Everything.
Just as epicycles were stretched to fit observations, string theory may be an elegant mathematical framework that ultimately obscures a simpler underlying reality. The video explores how scientific progress often requires letting go of beautiful but misleading ideas.
