Exploring the Limits of Physical Reality
This chapter examines the foundational limits in physics, including the speed of light, entropy, and energy conservation, and their implications for future civilization. It discusses theoretical scenarios involving faster-than-light travel, wormholes, and the complexity of quantum mechanics that challenge our understanding of time and causality. By navigating the balance between speculation and rigorous scientific thinking, the chapter sheds light on the constraints that underpin our knowledge of the universe.
