Is it possible to go into what has never happened yet with a time machine?

The concept of a time machine could exist, but it would take an almost infinite amount of energy.  The only way it could work is exactly the way you are asking,  You can only move forward in time, just at different rates.  So if you want to see the future then time would need to slow down for you and the world would have to speed up.  After a while you could return to earth and it would be the future.  \nFrom what is presently known about physics you can only move forward in time only at different rates from an observers point of view.  Believe me if we could travel back in time someone would have already screwed it up something big by now.\n\nThis is a one way trip, good luck

Only if travelling long distances in time costs the same as short distances in time. In all the modes of transport I know, travelling long distances costs more than travelling short distances. Travelling long distances is also more dangerous than travelling short distances. Therefore, users can only afford to make a short ride back in time because a long journey is expensive and dangerous. \n\nSo, suppose it's Monday and Eric is the owner of the first time machine. Eric travels back to last Tuesday. There, his concubines Amie and Atria will be able to take the machine apart, so that Eric can't get back home, but Amie and Atria won't be able to replicate it, because they can't understand how it works, because the crucial part won't be invented until Saturday. The girls will wait until Saturday and then buy a time machine at the same store that Eric bought his. \n\nThus everyone who wants a time machine has to buy one on Saturday at the earliest.

What you have stated is quite true only that inorder to view what happened at thatime you will have to have like a super tellescope mciroscope (if theres any thing by it) inorder to view what happened here at that time time "x" It is not hypotheticaly possible it is possible by all laws the only thing is that currently we do not have that kind of technology.

Think about what time traveling to the past means. It means that the entire universe except the time traveler is in a previous state. Now, for the time traveler, his time is still moving forward. He is older in the past after his journey than he was before his journey. \n\nSo, you have an entire universe one way and our traveler another. Since there was no past that existed that had his time traveler self in it, where has he gone? What is more reasonable is a time traveler experiment you can do yourself  by sending a smaller part of the universe into the past and watching that as you move foreward. Sound weird? Well, you can do it by resetting your computer. It goes into a past state and you keep moving foreward. This sort of time travel sounds like a cop out but it is just what is generally described on a smaller scale. That is, the entire universe but the traveler gets re-set to a previous condition.\n\nI know this answer doesn't satisfy the mystery feeling one gets with the time traveling notion, but it's what we really mean.

Theoretically, time travel is possible. But current technology does not permit it. An interesting article appeared in Popular Science a while ago on time travel physics (see link). You're right about the stars - in that we're not looking at them in real time. In a similar vein, light from the earth reaches outward into space. An alien civilisation looking at us from far away through a telescope could theoretically view our past history. But light also weakens the further it gets away from its source, so to really look way back into our past, we'd need a really powerful instrument to detect such light patterns.

I would love to travel forward in time and see just how our wonderful island paradise has changed. I would also travel back in time to see how wonderful and simple life in Hawai'i actually was. Aren't you curious about that?\n\nHawai'i no ka oi bruddah!!!

You cannot go into the past beyond your own birth and the future for the same reason. In both cases non-existence cannot be overcome. You may live to 100 but you have not yet so....you cannot visit yourself, there is nothing to visit. When you get to 100 you can visit yourself at 20 and so see yourself at 100 and see the future that way.\n\nTime travel  will always be limited to a persons life time i am afraid and the events that occured during it. No hunting dinosaurs, Hitler killing, Cruxifiction visiting.\n\nThis is the reason no one from the future has visited us yet. Once the future becomes the present and they invent time travel they can but only if the people who invent it and use it are alive now.\n\nGet it.\n\nIt a paradox I know but.....

You would need a time portal machine

Sounds like a question i'd ask Doc Brown on Back to the Future, what happens when history is changed?  Playing with the space time continuum is risky business.  Have you heard of the Chaos Theory?  Any little event can cause major ripple effects that may be worse than the one that was 'supposed' to happen.  For example, you kill al the terrorists who flew into the WTC and Pentagon, which means there was no stopping of commercial airline traffic....which means the terrorists on the west coast were able to carry out their suicide missions...which means one of them struck a nuclear power plant that released radiation travelling world-wide.  You get my drift, and, oh by the way, there were terrorists who were ready to takeover aircraft on the westcoast, but thanks to the FAA clamp down on traffic, their plans were thwarted.  Their targets are unknown, i only picked a nuclear facility to make a point.

Science fiction has explored this in tremendous detail, and has come up with no solid answer.  I'm not going to, either, but let me see if I can share a little bit of thought to help you find an answer you're comfortable with...\n\nEnvision the existence of a human being as a path that the human moves along, moving only in one direction: always closer to the end of the path, and further from its start.  So far, so good?  (Mathematically, it would be a 3-dimensional curve in a higher dimensional space; (string theory wants it to be 10 or 11 dimensions, I hear) your perception of time would be caused by your traversing that curve.)\n\nNOW: Time travel says that there is a way of bending this path around so that, although you're still moving closer and closer to the end of the path, the path itself loops around behind itself.  Think of a rope that's laid on the floor in a zigzag or a loop.\n\nFirst: the person who is me in, say, 2020, and comes back to visit me in 2006 is not identical to the 2006 me: that person is further down the path...  I might not even recognize the future me as me...\n\nSecond: I suspect that what happens depends whether the path zigzags without crossing itself, or actually crosses itself, forming a loop.  What the loop would do is pure guesswork...  It might separate off (See: "The Lincoln Hunters"); it might do nothing (See: "The End of Eternity") or it might cause an incredible release of energy, possibly destroying the individual altogether, and maybe lots of other things, as well.  (See: "The Weapons Shops of Isher")\n\nUntil we develop the ability to travel backward in time, we just don't know; all we can do is guess, guess, guess.\n\nWhich is fun--and the source of a lot of good fiction I've read!

Reverse time travel is impossible, but believe it or not, forward is 100 % possible. Then an object reaches an extremely high speed, near the speed of light, Time around it will go slower and the object willgo forward in time faster than everythng else. Astronauts in the space shuttle also travel throught time, but because their speed is only a tini fraction of the speed of light, their time travel is nearly unnoticed.

Maybe the more relevent answer is God does not allow us to time travel.  The Rules of This universe seem to suggest time Moves Forwards, and not backwards, though Stephen Hawking has noted that some subatomic Particles can briefly seem to move backwards in time, not at any significant factor that would allow time travel.  So maybe God ste up this "Law" so we cannot do what you wanted to do with the video tape, making the question seem Moot.  Or the other possibility..is say you could time travel, and you could video tape.  Human nature dictates, some people will believe, and some will be sceptical (see Doubting Thomas for reference)   We have video proof of the Moon Landing, Picture documentation of the Holocaust, and still some people believe neither event ever took place.

1) You can't change a past event, that's nescessary for you to be able to change that past event. (You can't kill your distant ancestor)\n2) You can't go experience a future event, that requires someone from that future event to change your present event. (In the 'Planet of the Apes' movie series, Caesar went back to his past, and started an ape rebelion that built the world that Charleton Heston visited when he went into his future)\n\nBut how would you know? Changing the past or the future might create a tangent universe, that we can't experience.

Firstly, don't overly concern yourself with the concept of fixing the past.  As a numerologist, Norman Shine, stated in one of his books: "Worrying about the future is just as escapist at living in the past."  In other words, if you spend all of your time worrying about the past, then you are wasting the present time and will have a very bleak future.\n\nIn regards to theories of changing the past, that's a theoretical astrophysics debate as well as a good philisophical debate question.  Either:\n\n1.) You can change the past and affect the direct future.\n2.) You can change the past, but the now new future is the future of another/parallel universe.\n3.) Somehow the laws of nature will prevent us from preventing the past/future (depending on your origin of time).\n4.) You change the past and cause a paradox and at that very moment the universe ceases to exist (according to Dr. E. Brown on Back To The Future)\n\nMy advice is to try and correct what is going on in the present to help your future.  You cannot change the past (that I know of), but you can change the future.  It may not be easy, but it is more possible than a quick-fix time machine-changing past patchwork.

Einstein said we are living in the past time, that means we have not "now time"!\nSo, nobody can not answer, what time is it! maybe we can ask, what time was it!!
