Consider this: we only know that time exists because we have memory. Likewise we know that space exists because we have vision. Those are the result of a biological evolution. We can see time as a flow (as most do) but we can also see it as a succession of moments, each one being a different "universe." Does it sound strange? Ask yourself this: Is the future already "written?" If not, then there are a nearly infinite possible outcome of any event. Are those different "universes" or only a new dimension to "time?"
We can only observe the universe from "here" and "now." That is basically what Relativity tells us. "We" as our consciousness, is the memory of brain. If time is unlimited, what can happen, does happen and not only once but an infinite number of times. When it happens again, is it a new event or a new observation of the same one? I think it is the latter.
... but I digress. We know nearly nothing about time. My answer to you would be: If we can travel in time, then it wouldn't be "you." Does it makes sense?
Yes. I can travel forward in time, although this is generally true of most others too. That travel is rather slow by some standards, taking exactly 1 second to travel forward in time by 1 second. Yes, I expect you will say this is a less than interesting way to time travel, but it beats the alternative, of no such travel at all.
There are other ways to travel in time. One can use the relativistic mechanism. Thats is, if you travel quickly enough through space, then time will slow down for you. Effectively, this means if you can take a long trip in space at a velocity near light, the the rest of the universe will have experienced time moving at a different rate than you. The net is you will return having aged less than the world you left behind. Is this time dilation effect really time travel? That is arguable. And a real problem with this method, is you need to achieve velocities that are a VERY large fraction of the speed of light to get even a minimal time dilation. Sadly, those velocities don't come cheaply.
Travel backwards in time is only possible by memory. Read a good history book, written by someone who can make you feel what really happened.
Sorry though, if you insist on better methods of time travel than these, you are probably out of luck. Time travel is a great toy for the fantasy and science fiction writers, but it really is mainly fantasy, not science.
Sort of...but not like you read in Science Fiction.
If you leave earth in a space ship and travel at the speed of light or close to the speed of light, the time on the space ship compared to the time on earth will be different.
If you are gone on your trip in space for a period of 20 years according to your clock on the space ship, 100 years would have elapsed on earth. Those are the exact numbers, but you get the idea.
Yes. Einsteins Theory of Special Relativity. Depending on your speed and gravitational tug your clock can move faster or slower than others. For instance if you seen something fall into a black hole they would only go so far before it would seem to you that time had stopped but for them it would seem time was moving at a normal rate. Also a black hole also remains thus because at the event horizon time stops....Traveling to the future is easy its traveling to the past that's hard.

Theory according to Einstein

Oh drat, I just moved a few minutes forward in time because of your question.
Of course it is. Just, you know one way at a constant rate into the future.
It is like speed travel.And any other travel, it is just axis as you know.t=v/s
Only is science fiction, not in reality.
Yes.
I don't know how or when it will happen, but it will happen: both ways.
No. Never.
