Space Time
"Space Time" explores the crucial question of how humanity will perceive and measure time as we become an interplanetary species. The book examines the limitations of Earth-centric timekeeping and the necessity for a universal time system that accounts for relativistic effects. It argues that as space exploration advances, particularly with long-duration spaceflights, a shared and scientifically accurate method for coordinating activities and maintaining a sense of time is essential.
For example, the differing daily cycles on Mars compared to Earth highlight the practical challenges of using traditional timekeeping methods in space. The book progresses from the historical context of timekeeping to the complexities of interplanetary time, including the mechanics of time dilation during high-speed space travel. It delves into potential solutions like atomic clocks and pulsar-based timekeeping. "Space Time" uniquely emphasizes the human element, considering the psychological and cultural impacts of redefining our fundamental understanding of time, not just the technical aspects. The book draws upon research in physics, astronomy, and engineering, with data from space missions to illustrate the practical challenges of timekeeping in space.
