Time Travel will never happen. If it could ever happen, we'd know about it by now. Sometime/somewhere in the billion years of possible existance someone had to slip up, or even decide to tell people and show them it. Or they'd go back in time and fix problems. The point is, if time travel did or ever will exist, we would be aware of it.
What about aliens? What they are claimed to look like "gray human shaped persons with big heads" is interesting because the reason we evolved from Monkeys was the increase in our brain capacity. They never come down to earth, they study us and our progression. Not saying I believe this, but just a thought.
we do know about it now, because the did go back in time and thoroughly screw things up by doing so. there would never have been the greek and especialy roman empires of our now messed up history if they hadn't. nor would a number of unfortuate things that have resaulted from there having been. as for the 'alien'/'greys' thing, there's a big sillyness in it of not recognizing how big and unimaginably diverse the universe we're surrounded by really is. sure there could be SOME WORLD somewhere, that the people of THAT world might be those 'greys', but there are a NEAR INFINITY OF UNIMAGINABLY DIVERSE WORLDS, world'S', PLURAL, out there, EACH WITH ITS OWN physical appearance of the species that evolved creative sentience on them! nor is it at all probable for a life form evolved on one world to healthily even nontoxicly, breathe the atmosphere of another. you could land on a world somewhere, with all the same components in its atmosphere as our own, but only a few percentage points difference as to the proportions of the mix, and keel over before you could draw your second breath. so this idea we see in star trek and star wars and anything else based on an "all human" universe, of persons of species evolved on different worlds, walking arround breathing each other's air on some, any, one same world, without atleast something like scuba gear or some pretty fancy gas masks or something, really is a bit of a stretch beyond credibility. really everyone not native to whatever world such a meeting were taking place on would have to have their own breathing mixture. now that being said, of course there ARE people, and i don't see how you could call creative sentients anything other then people, no matter how completely different their physical forms, out there, on as many zillions of different worlds as their different life forms are from. but these are really entirely seperate questions (time travel and extra terrestrial aliens). and yes, though of course i can't empericly prove either proposition, both quite certainly exist. (and nontangable spiritual beings are an entirely seperate question from extra terrestrial tangable people too) =^^= .../\...
Eh? Why do the roman and greek empires proof time travel? They were pretty normal, but i admit innovative and progressive, civilisations that followed up older ones.
saying people in the future would come back to the present is the lamest thing i've heard to try and say time travel isnt possible "TIME" is all an illusion, the future and the past are only visions the brain makes up to conceive this "time" however, can u say that your whole life is not lived in the "now" ? every single moment you will ever experiance in your life, is provided to you in that present moment so viewing it this way, how would it be possible for beings to live ahead on a seperate plane in time? the biggest hurdle in time travel is creating a vessel which is capable of transfering solid matter into energy, then reforming on the other side of, what most likely would be a black hole although very far off, i belive time travel will one day be possible.
Well the thing with time travel you wouldnt ever know the changes... Maybe we can meet someone from the future but wouldnt that mess up "his/her" future, or wouldnt we be living in a perfect world, but oh well traveling thru time shouldnt be nessesary... lets just be careful with what we do and focus on the problems of now and take care of them now or their wont be a future.
1st of all...i COMPLETELY agree with you. BUT, do you think its possible that in the future a time machine will be built, but there is a law or something to say you cannot alter the past!!! That might be possible
