If time travel were possible would you try it? Would you want to go back and fix a wrong? Would you dare to tamper with past history? What if you could go back and buy stock in a company that you knew would skyrocket, thereby making you fabulously wealthy when you returned to your time, would that be something you would do? Would there be a moral dilemma, is it right or wrong to do such a thing if it were possible? If the past was altered would it actually change events, or would a different action occur that ended up taking the same path through history and cause the present to be the same? If changing the past affects future events then it would follow that present actions affect the future, or do they? Perhaps the history of the world and humanity is on a predestined course that will take us to the same place regardless of our actions. Should that be the case, then it matters not what we do. The destination would be the same no matter what. Finally, are we as humans meant to achieve a higher level of existence, or do we simply move through time doing whatever it is we do and eventually perish from the world like so many species have before us?
