The concept of time most people have makes absolutely no real sense if you think it through....
first off, let me try to explain time from a different perspective: time is NOT a property of reality, but a means of measuring changes and cataloguing experiences. what I mean is that there is only ONE total system of elements, matter energy spirit, whatever...and the number of these elements never grows nor shrinks in number but like lego blocks can be taken apart, moved around reshaped and reformed, etc...but never added too nor subtracted from.... what we call time is the experiencing the changing patterns and relationships among these blocks compared to some apparently stable cycling patterns of these same blocks... example, earth rotation proves a somewhat stable cycle which we call a day relative to the sun... babylonians with an obsession for 12s and 60s divided the day into 12 basically equal parts and night into another 12, calling them hours, sub dividing those into 60 parts, minutes, etc... by a comparison of the relationship of the earth to sun, they could say such and such an event happened at such and such a time. so time requires the following: changing relationships, some stable cycling countable relationships, and most important, someone to notice with the ability to count and remember... without all these elements there is no time at all, only the present moment with changing relationships.
there is thus no future, other than our experiences projected into anticipations, no past, besides our memories of former positions. Thus predictions about the future are only guessworks unless you have the ability to manipulate all elements... as to standing outside of time, each and everyone of us can be said to do this as we are always in the eternal now, the present moment... we are never in the past, nor the future...those are only mental inventions.
the concept of time travel is just human silliness...there is no other time to travel too.
Consider what it means to travel to the past for example... you would have to take every single block of matter and energy and put them back to where they were to get to the time you wanted to travel back to... no machine can do this... since the blocks only have ONE existance you cannot leave them where they are now and go back to where they used to be and expect them to still be there.
there is no explanation for where any extra matter and energy can come from to make each unique moment, conservation of matter and energy demands that only one total set exists no more, no less.
assuming I am completely wrong and the western view is right, claiming one could travel to another time... think of a omni-dimensional being, god if you like, looking down upon our world time as a movie with one frame per moment of existance [each moment is like 10-43seconds in length according to the notion of smallest time scale]..... our god sees every single moment in existance, one complete movie reel... the problem with this is that not one of those frames is the present moment and there is nothing moving per se....
if we think of God as putting the film into the projector to make it move, then all motion exists beyond our worldtimeline and not in it, so our sense of motion cannot be explained, how do we see and feel movement of any sort? we must be outside the film as well--once again in the eternal present, which would mean that everything we experience is just a movie and we have no real stake in it, no real choices, no real part other than audience... and so we could not really become time travellers in any real sense either, other than to learn perhaps how to move the film to any location we desire.
