Time Travel
While Time travel is technically possible and there are civilizations and individuals that discover or develop this ability, those doing it find that they cannot alter time by traveling into the past. The very act of traveling back through time creates a new alternative timeline and a new universe. Traveling into the future does the very same thing and the future observed is not the same it would have been unobserved. So true time travel (remaining on one-time stream and in the same universe) is prohibited by the RULE.
Time travel is the concept of movement between certain points in time, analogous to movement between different points in space by an object or a person, typically with the use of a hypothetical device known as a time machine. Time travel is a widely-recognized concept in philosophy and fiction. The idea of a time machine was popularized by H. G. Wells' 1895 novel The Time Machine.
Human Understanding:
It is uncertain if time travel to the past is physically possible. Forward time travel, outside the usual sense of the perception of time, is an extensively observed phenomenon and well-understood within the framework of special relativity and general relativity. However, making one body advance or delay more than a few milliseconds compared to another body is not feasible with current technology. As for backward time travel, it is possible to find solutions in general relativity that allow for it, but the solutions require conditions that may not be physically possible. Traveling to an arbitrary point in spacetime has very limited support in theoretical physics, and usually is connected only with quantum mechanics or wormholes, also known as Einstein-Rosen bridges.
