This Book Is From The Future: A Journey Through Portals, Relativity, Worm Holes by Marie D. Jones and Larry Flaxman explores the history and science of time travel, wormholes, parallel universes, time warps, and coexisting timelines. The book begins by defining time from years to the yoctosecond which is beyond the shortest time measurable by any current machine or process.
The authors explain that entropy does not work in reverse. The forward arrow of time increases entropy but time does not flow in the reverse direction. A hot pot of water gets cold due to entropy but a cold pot of water cannot get hot without some other interfering factor not in the original equation.
Jones and Flaxman explain how logician and mathematic Kurt Godel worked with Albert Einstein to formulate a theory that time travel into the past was possible provided that the universe was rotating. Godel hypothesized riding a circular or spiral path allowing him to go back to the past and return to the present. Physicists would later argue that Godel’s universe, if finite, would remove the time travel aspect completely making everyone more comfortable with the theory.
The book depicts the Lorenztian Wormhole pictorially and explains that the black hole would be the entry point with the white hole as an exit point. The practical implementation problem is that entering into a black hole will meet with infinite gravity and be crushed or stretched into nothingness or an incomprehensible gravitational effect.
The Casimir Effect proved that negative energy densities can happen in nature. Logically, this negative energy density could be the mechanism needed to stabilize the entry point of a wormhole long enough to travel safely through without being torn apart from the tremendous forces within. Steven Hawking hypothesized about building a time machine, saying “All you need is a wormhole, the Large Hadron Collider, or a rocket that goes really, really fast.”
The authors take us back to one of the most famous time slips. Charlette Anne Mobley and Eleanor Jordain (two educators) allegedly had a time slip in the Gardens of Versailles in 1901. The two were looking for a path that lead to Petit Trianon, the private palace of Marie Antoinette when they found themselves transported literally back in time. The people around them appeared to be frozen in time. There were no effects of light and shade. No wind stirred the trees. At one point, the women rounded a building and returned to the normal state.
This Book Is From The Future is a fascinating entry into the potential world of time travel. The book is well researched with proponents on both sides of the feasibility argument. The contents of this work will provide rigorous debate over the notion of time travel until working models are built and tested in the coming years.Powered by Sidelines
