This article analyses time travel and how it might be possible or impossible.
|Traveling back and forth in time is a stuff of science fiction. Science fiction writers have long harped about traveling in a time machine to other time backgrounds in the past or in the future. Building such a time machine perhaps is still in their minds. Traveling back and forth in time is like picking books on shelves in a library. We can lift the books we want and read through pages. Traveling in time is similar in that we travel to those time backgrounds and live our lives there.
Traveling in time would require creating instances of present spacetime in which we will have to transport ourselves. Else, if we suppose such time and space instances do exist, we will have to find ways of entering and exiting them. Much of this sounds very high flying and is still stuff of the future. Many people have claimed of time travelers from the future living among us. This cannot be vouchsafed and is still a thought shared among us. Real time travelers will require a way to travel back in time to their native lands. How this can be achieved is still thought provoking. Time as we know may contain other dimensions still unexplored and this dimensions might have more areas of operations than what we have. It is difficult to imagine how life would be in such dimensions. Inter-dimension travel can be another interesting activity in the minds of scientists that can be explored. Having dimensions such as the fifth and sixth may make us think in different ways.
