This volume is an examination of the profound revolution of the early 17th century, a transformation that reshaped our comprehension of the cosmos. This pivotal shift represented a departure from the longstanding notion that planets merely acted as markers on material spheres orbiting Earth’s core, with the outermost sphere serving as the cosmic boundary. In this era, a fresh perspective emerged, one that welcomed the concept of planets and stars as self-contained entities in an endlessly expanding space.
