Time travel could reveal the underlying structure of spacetime from "summary" of Time Travel in Einstein's Universe by J. Richard Gott
In the realm of time travel, there is a fascinating possibility that goes beyond the idea of simply moving back and forth in time. It is the notion that by engaging in time travel, we may be able to gain insights into the fundamental nature of spacetime itself. This concept suggests that the act of traveling through time could offer us a unique perspective on the underlying structure of the universe. When we think about spacetime, we often envision it as a four-dimensional framework within which all events occur. This framework is intricately linked, with time and space intimately connected in a way that forms the very fabric of our reality. However, the true nature of this structure remains somewhat elusive, with many questions still unanswered. By delving into the realm of time travel, we may have the opportunity to unravel some of the mysteries surrounding spacetime. As we navigate through different points in time, we could potentially observe how the fabric of spacetime behaves and changes. This firsthand experience of traversing through the dimensions of time could provide us with valuable insights into the underlying mechanisms that govern the universe.- The act of time travel could allow us to witness how spacetime warps and bends in response to various factors. We might observe how gravity, velocity, and other influences impact the very essence of spacetime itself. These observations could offer us a deeper understanding of the intricate relationship between time and space, shedding light on the underlying structure that defines our reality.
