In a way I think it has but maybe by someone from the future who has gone to the past which in turn would mean that the actual first time would be overwritten by the fact that he went to an earlier time and used the time machine then but has been manipulating time in a way that now we think history altering events happened because of certain circumstances but in actuality it was because there's a dude out there that stepped on a cockroach with an anormal DNA chain which had it lived and reproduced would have developed a defense mechanism that allowed it to smash its own atoms and create mini nuclear explosions that reached a distance of 100 yards. Making them rulers of the Earth.
The fabric of spacetime is far ahead of our kind's understanding, for now at least. It would probably be millennia before we could truly understand the true structure of time.
For now, we can only speculate. Is it simply an artificial construct of sentient thought used to rationalize the arcane nature of the universe? Or is time a quintessent physical force governing all aspects of reality like a rushing river? Is it an unwavering constant, flowing at the same speed and direction throughout the universe? Or is it as malleable as all the other forces, capable of altering speed and even direction when manipulated properly? And what of it's nature? Is every action and occurance laid out before us like a video casette tape, with history being unchangeable, and free will being a mere illusion? Or is time truly unpredictable, with changes happening all the time across reality, nothing being permanent for anything more than 3.14 seconds?
These questions cannot be answered currently, as we do not possess the means nor the machinery to probe the fabric of time, if such a thing even exists. For now, we rely only on fiction for inspiration and guesswork, and the hope of one day discovering time's true nature...
Never. Even if we could, it would be impossibly illegal.
Perhaps.
The radiation would be a problem though, but the idea of time travel could be possible.

We should ask Stephen Hawking, nigga be all kinds of smart.
To human knowledge it's impossible. But then again at one point in human knowledge if you told someone that there are tine little things that fly around in the air and make you sick they would have laughed at you. Even if the human race discovered time travel I don't think it will be used due to the fact that if you did travel back in time you could change all of human existence with the smallest mistake.
The current laws of physics are but an idea, a theory. Just because a grand speculator popularises an intriguing idea, doesn't mean he/she's hit the nail on the head. We are but babies in the eyes of the universe, still writhing in our cots, with barely any understanding of the universe, watching the stars twinkle above us. To truly answer the great questions of reality, we must grow up first, over the course of the aeons, allow our capacity for knowledge and understanding to truly grow.
Like I said, it will probably be millennia or even millions of years before our kind can understand but a fraction of the universe's nature. We cannot see the outside, for we are still in our cots. Sure, we can peer through the bars, and observe the pretty duck wallpaper adorning the walls of our room, but we don't know what lies outside the window or beyond the door. We cry out for the loving attention of our parents, but none hear us, for we have no parents, and even if we did, they are probably rubbish chavvy teenage parents who can't be bothered to look after their kids, stuffing their faces with their chicken an' their chips as they gawp at Cronos Hill's Galactic Burp. But most likely we never really had any parents, and simply grew out of the cot from the seeds of ancient life.
But one day, perhaps our cries will be answered, not by our parents, but by either the cries of another baby (alien race), or the attention of some kinda celestial nursemaid (space deity), although the former sounds more likely. If it is the former, we'll be in the nursery as an toddler, playing with our building blocks and rag dolls and toy cars, although we'll also be squabbling with other toddlers. And even then, we'll still have a LONG way to go before we reach pre-school and learn our ABC's, let alone discover the apocrypha of celestial knowledge when we go to university some 20 eons later.
All in all, we are babies, and can't understand anything just yet.

Don't think so, at least not in the sense that you can come back and interract with shit, otherwise, someone would've did it already and we'd know about it.

You sound like a philosopher :3:
But with words of wisedom
Maybe it's possible. I think there could be something to it. But I also think there would be no paradoxes or alternate histories as per this:
[url]http://en.wikipedia.org/wiki/Novikov_self-consistency_principle[/url]
It would probably be very costly and complicated to execute, involving exploiting time dilation and several quantum mechanical phenomena. And ultimately would not be able to go further back than the point of creation.

Cheers. Some people tend to knock some of my philosophies as "silly" or "rubbish", but I do sometimes produce pearls of wisdom. It's all about metaphors and observation, y'see.
Also, very important thing: no-one is completely and truly right.
Well "Mr. Smarty Pants Movie Star" Michio Kaku says there's no law that makes time travel impossible. But I don't like him.
I've always felt that time travel might actually in fact be possible, but you can't travel any further than when the device was actually created/turned on.
If we do, First thing I'm doing is creating a time paradox.
It does though, I just traveled back in time from page three.
No.

As I sometimes say: "If you know the science behind it, the cosmos becomes so much more amazing".
(Yes, I'm hoping to work with Astronomy in the future.)
Indeed, although science is merely interpretation and catergorisation, used to attempt to understand what's really going on.
Nothing is final, pretty much everything is more or less theory. Sure, we can speculate and observe, but in the end it all boils down to interpretation.
No, because if it did terrorists will just go back to the past and kill everyone with their futuristic laser guns or something.

Or build an portal to enter our imagination and break the wall that seperates the evil from the good.
Nope.
If it's created, only the government will have access to it, and, obviously, since the government is stupid they would end up fucking everything up
It might be possible. In about a few thousand years.
I always thought that if we did figure out time travel, that you must not be able to see yourself or something because if you went back in time to when you were younger, your younger self would see you and I'm pretty sure that you haven't met your future self, have you?
Maybe.
I'm traveling forward through time right now am I not?

I never really understood why it would cause a rip in time and space.
by waving my hand I move it nanoseconds backward in time!! :science:
It might be possible, but I think the human race will go extinct before it happens.
Altering the past and its impact is the most confusing thing to think about :psyduck:. Technically, if the human race does survive to see it, we would have experienced someone coming back in time, well, if they knew what the planet earth was and where it was located.
It is very possible to time travel. There is no law of physics that can prevent time travel, take a look at black holes. You have the center of the black hole (forgot name) where anything can happen, come out, or be destroyed. The only problem is the earths rotation around the sun. When the time traveler's device and him go into the warp of time there is no gravity property, meaning that he will not stay on earth so he has to plan his time extremely correctly so that he does not re-appear into anything or else the molecular structure will destabilize. Another problem is the warp of time. Science does not know anything about the warp of time like pressure and properties, meaning that if the pressure is too high or low when you get back to earth's gravity pressure you could be crushed or stretched dramatically, basicly you could die. The other thing is new development, buildings are always building. Its the same thing with clipping into something, the structure of the molecule will fail and a wide range of everything will disappear into nothing. Another thing is the fact that there is no past or future because EVERYTHING is in the now. Trying to time travel could in fact destroy everything in space and time so that would be the end. Nothing new would happen. So time travel is possible but very risky.
