Scientists believe that traveling through time is theoretically possible under the right conditions. In physics and in science fiction, a method of time travel is often speculative at best. But what if time travelers actually existed? How would we perceive them? And what are the consequences of their actions?
Albert Einstein’s Theory of Relativity predicted the existence of wormholes in outer space. By using wormholes or an Einstein-Rosen Bridge to fold the fabric of space-time and traveling in a specially designed spacecraft to travel great distances beyond the speed of light. Taking into account of Einstein’s wormhole theory “shortcut” through space and time, a new wormhole theory developed in 1988 called the Morris-Thorne wormhole hypothesize that traveling through a wormhole would allow a traveler to leave one part of the universe, and instantly appear in another part of the universe by connecting two points in space time through the wormhole, which not only would mean instant travel beyond the speed of light, but also allow time travel as well.
This kind of scientific method for traveling through time has been described and explored in literature and TV and films for decades. In the TV show Star Trek had warp drive to transfers across the galaxy by warping the space-time continuum. In the film Star Wars had hyperspace to achieve faster than light travel enabling starships to reach other star systems. Carl Sagan’s movie Contact and novel by the same name had his space explorer traveling through a series of wormholes designed and set up by alien beings. In the movie and TV series Stargate, had a collection of time space portals that were discovered and used to create artificial wormholes for traveling across the galaxy and time.
Scientists today speculate and consider the possibility of time travel as a real phenomenon. But they also elaborate that such a journey through time could have consequences such as going backward in time and in the far future. For theorists conjecture that traveling through a wormhole would actually lead you to a parallel universe or alternate reality, and that any changes you make there could have dire consequences. This could establish a new timeline, a series of events and scenarios, that could affect the past, present, and future.
The time traveler may find himself materializing in a completely identical universe, but in actuality on a parallel world very much like his own, however, in an alternate reality setting. But with subtle differences that could range in the infinite possibilities of choices made by counterparts living on that parallel world. Such was the case demonstrated in the science fiction series Slidersin the mid-1990s. A young scientist had created a device using the Einstein-Rosen Bridge theory to slide into alternate realities and found him and his companions lost in a series of multi-universes where all of history and futures scenarios are played out.
