I recently came upon a post exploring the possibility of Time Travel. In that post the writer, ( my friend &tarunandlaxmi ) pointed out that most conventional scientists of our day think backward time travel, or traveling into the past is an impossibility. However, according to Relativity Theory skipping into the future should be quite possible, given the ability to attain great speeds approaching but not quite reaching the speed of light. We aren't that fast yet, but if we should live long enough, and attain sufficient technological advancement, relativistic speeds are within our grasp. When that day comes, the principles of time dilation will make future time travel very possible. However, by that method, it is a one way trip. There would be no way to come back with that particular technological approach. But we are still left with the question; is it possible to travel back to the past, by some other technological method?

In part 1 of this series, published here at Bubblews, www.bubblews.com/news/454618-time-travel-some-say-impossible-but-is-it-part-1 we introduced this debate, and discussed how as a consequence of Professor Einstein's Relativity Theory, approaching the speed of light creates the phenomenon of time dilation, which is effectively time travel forward into the future at an accelerated rate. This kind of forward time travel is however theoretically a one way trip, without any opportunity to return from that future to your originating "present time". We also dealt with the first, (weakest), of the major arguments used by time travel detractors to justify their unproven stand that time travel into the past is impossible. Here in part 2 we will move on to talking about another much stronger issue; the so-called paradox problem, often employed by those who declare backward time travel impossible. At first glance, this argument appears quite sound, but to really examine any subject properly one must do more than just glance at it.
