in reply to Mindship's last post.....
we readily accept the possibility of alien life because it is not only possible but probable based on our knowledge of the universe. The idea does not conflict with our knowledge of the universe thus far as time travel does. Time travel to the future via time dialation is indeed possible........not only possible, it's fact. It's been done....fractions of a second but still it's been done. Travel to the past however makes no logical sense based on the way we humans percieve and define time....a dimensional point to coincide with the 3 viewable physical dimensions of space preventing 2 seperate objects of matter from occupying the same three physical dimensions.
I myself think the idea is completely loony.......yet possible if new knowledge is discovered about our universe.....knowledge of a naturally existing way to jump back to a previous point of the space-time grid. The question of "where are they" does not apply to this subject at all. No non-naturally existing form of time travel could take a person back in time before the machine or whatever itself was made.....impossible....the machine must have been in existence in that previous time to have a doorway to exit through (as used in the movie Primer). If nobody has invented a method of time travel yet and built the means to do so......it is impossible for time travelers to be here now as there is no doorway constructed to allow them access. This is ofcourse moot if there were a naturally occuring method of time travel......which the question "where are they" certainly applies.
Even if one were to look at the subject from the fiction point of view that most do.......time is still a dimensional point of the space-time grid. It is the only thing that prevents to seperate objects of matter from occupying the same space. What do you sci-fi nutjobs think would happen the instant somebody leaped back in time to co-occupy the time dimension at the same time as another object? It's not like Back to the Future people. Matter is everywhere. Your magic DeLorean leaps backward 50 years only to land in the same time-dimension as a fly, a spec of dust or pollen in the wind or any other object.......what happens? It's not collision as there is no momentum, it's fusion..........what happens during fusion?........yeah..... I think I'll stick with the present.

I don't think it is, as in the 'Back To The Future' type of time travel. I know time actually slows down the faster you go, but I think the closest most of us will come to time travel is driving a car or running as opposed to walking. The faster you get from point A to point B, the faster you travelled through time. Right? Maybe?
nope not unless you're a cartoon

Kinda reminds me of (I forget where I first heard it)...
"Time is nature's way of keeping everything from happening at once."
In any event, if your theory of "no-time-travel-before-invention-of-time-machine" is accurate, it would certainly explain why we have no visitors...yet. 😉

Think of time like a candle. Slowly burning out. You cannot bring back the candle and if you try it will just be mush shaped. The only way of sort of time travelling is to put a computer in your skull and relive memories. But if you can recycle candles then think of a camp fire burning.
There is always a problem with analogies of time, that have time in them. If you could rewind time the candle would remake it's self from the flame.

Well, here's a thought I would like some comments and opinions on.As far as I understand, most people (scientists and laymen alike) look at the vastness of the universe, and purely as a numbers game figure that Earthlings are very likely Not the only intelligence. Yet as the famous, late physicist Enrico Fermi so eloquently put it, if they are out there, "Where are they?"
This has come to be known as the Fermi Paradox.
Applied to time travel: if it is possible (and I believe theoretically it is, but I could be wrong), then one would think that sooner or later we would get time travelers from the future. But as Fermi might have said here too: "Where are they?"
In other words, if most of us so readily accept the notion of aliens, are we as quick to acknowledge the possibility of time travelers? If not, why not? [B]Why one and not the other?
[/B]
Sorry but to go off on a slight tangent it seems to me that the argument of "where are the aliens?" seems pretty stupid. How much space exploration have we done? I mean c'mon geeeezz, we send a space probe to Mars and where like "wheres the aliens?" Is that a paradox?
Furthermore isnt it a good posibilty that aliens are already here but we cant percieve them. Im not buying that at all arent there supposed to be other dimension as well, what so there are no aliens there as well? A better argument is that aliens exist but they either live to far away or they're here already.
