Time Travel is no more an Impossibility. At least, Time Travel to the Future is not Impossible. The Validity and Scope of the Concept of Time Travel to the Past has not yet been proved. Still, everyone (or at least, most of the people) expects Time Travelers from the Future, and not from the Past!
Why So? Have you ever thought about this?
I bet that you haven’t. Almost all of those people who consider Time Travel as a Possibility, expects Time Travelers from the future and not from the Past. Well, normal people don’t have any Specific Reason to think so. They expect Time Travelers from the Future because even the Earliest Films about Time Travel actually dealt with Time Travel to the PAST. So Normal People have a silly feeling in their minds that Time Traveler will probably be from the Future and not from the Past.
Another Logical Explanation? Oh Yeah!!
There is another LOGICAL EXPLANATION as to why People with Scientific Knowledge expect Time Travelers from the Future. As of Time Travel, people from THE FUTURE will have a LOT OF MEMORIES to get back to and a lot of People to revisit. It is more likely that if anyone is able to Perform Time Travel to the Past, then they would surely visit their lost ones or will try to get back to Precious Memories (unless Time Travel to the past happens as an Accident). ON THE OTHER HAND, People from the Past will be afraid that they might lose their Precious ones, but some of them might even be excited to see Cool Technologies of the Future.
A Simple Logic
Almost all people who believe that Time Travel is possible, supports the Traditional Model of Time Travel. Why? Because most of them are Unaware of other Models and Types of Time and Time Travel. Since they believe in the Traditional Model of Time and Time Travel, according to them, there is only One Timeline. In such a Model, a Method for Time Travel to the Past should be discovered for Time Travel to the Past to happen. In such a Situation, Time Travel “from” the Past is impossible, because there is no known Method of Time Travel, in the Past.
But there are many other Models of Time and Time Travel. There is a higher possibility that the Traditional Model of Time and Time Travel will be ruled out by Scientists in the nearby future (Actually, I did that in my Book by solving TEMPORAL PARADOXES).
So you can expect both Types of Time Travel, but there is a Higher chance that Time Travelers will be from the FUTURE and not from the PAST!!!
