Wouldn't the earth just have to go back to the same exact place where it was at that time you want to go back to, because think of how fast we're moving. So is time travel possible at all?

it is not possible, the earth cannot go back, time moves only in one direction, foward. also, the fact that time is just a concept that humans created. since time is relative, it cannot be changed

It is possible to time travel, but only in theory. To travel back in time would require getting near a wormhole, which is obviously very difficult, considering wormholes are currently just a concept that has not yet been proven. To travel forward in time is also possible, but only if we can go at the speed of light, making anyone traveling at that speed age slower relative to the rest of the world. Matter cannot even travel at the speed of light, so I dont think we can expect a human being or any other being or object to time travel.
About your idea: Making the earth move backwards so that it is in the same position as it was at the time that you wanted to go back to wouldn't work. Even if we managed to move the earth, would all the people go back to where they were? Time is experienced when a change occurs, and there are an infinite changes happening at any one time; if one lonely planet in a desolate galaxy moves backwards, that doesn't mean that all the rest of the planets and stars and people and animals and objects will move with it.

I don't think that the whole earth could return to the same exact place. It would need a lot of energy. However, maybe in the future we can travel to the future only if we can avoid to became a energy when we go through time traveling in a speed of light.

Since we do not appear to have had visitors from the distant future (when time travel, if possible, would be reality) I do not think you can do anything other than travel into the future at the rate of 24 hours per day

First, time travel is not possible. We don't have the luxury of plentiful di-lithium crystals and warp-speed anti-matter engines, but to transport a person to a speed nearly matching the speed of light would be awesome. Remember E= mc^2. When an atom bomb goes off, m is less than 1 kg. As for different time systems, that is one of the results of relativity theory; time is also a function of the speed of light.

Maybe it is. Maybe we could travel backwards in time. Maybe the reason that no one else has visited us is because they need two doors to travel backwards. You know like door no.1 is linked to the past and door 2 is linked to the future. So without door no. 1 noone could go back.

Nope, because it creates too many paradoxes. Like could you go back and change your own life? Or if you went to the future and did something, would that change the present? Would you even exist at all in order to go backward or forward at all?

UFO's are humans from the future traveling back to look at us.

ask EINSTEIN. he proved that its possible if you have as much energy as one star. and also it takes about 100 million years to get an ounce of that energy and since we're probably not going to live for that long, it is IMPOSSIBLE!

idk. I hope.
i think if we find a way to dream what evr we want we could travel back into time with free will.
Scientists and the Scientificalal Geeks are tryin to figure out.
Just kidding sry. But i was serius about the dream thing.
