Is it possible to go back to the past? I heard traveling to the future is easier(theorically)to explain, it is just a matter of speed. But towards the past is a chaos to explain.

Well as time is naturally travelling forward, it would be much harder to reverse it. You would have to go forward to go back. Perhaps if you generated enough energy to physically distort the time/space around it you could carefully create a wormhole that would either re-create that time-zone, thus bringing back past events or 'travel' through the wormhole to another point backward in that timeline.

Actually, there are loopholes in physics that would allow for "time travel". However, one must remember if such a thing were possible there are a number of paradoxes that would prevent us from interacting with it in any way. We could observe, but couldn't interact because we'd be experiencing what had already taken place (future or past). Observing the future would actually be more difficult than the past. Because as an object reaches the speed of light it regresses in time. To travel to the future one would have to bend timespace by other means than solely speed. It would entail distorting timespace dynamically.

There is way of traveling to the future today, is going to the space. A spaceship is so fast, that you actually travel to the future. It has been documented in long trips when the atomic clocks in the ship get delayed compared to the ones on earth. If you go on a shuttle you will only travel in time just fractions of a second, but that proves that you can travel to the future, and Einstein's theories. there is no way to know, with modern physics and observations, if is possible to travel to the past.

Certainly it already IS possible somewhere in the future since the past, the present and the future exist parallel to each other.
Perhaps not in that form we see it on the movies, at least to me it seems less possible that we would be able to take our bodies there, but in a way that we still do not understand, it will be possible, call it some sort of communication, using our present terms.

There is no possible way we can travel in the past, for the simple reason no-one (not even the insane) have ever stated they're from the future. Think about it, if there was a way there would have been some documentation of someone saying they were from the future................how much future do we have? If the Americans keep voting for Bush not much I presume! I think he's living in the past...............

No. that's the worry with sci-fi: it clothing up delusion to look like actuality whilst it is not. Then people who do not comprehend to any extent further useful initiate questioning that one and all which stuff they have seen/study is actual whilst it is basically delusion. Going swifter than gentle has not something to do with technologies. basic technological awareness says it is impossible. in case you probably did hypothetically exceed gentle velocity, then each particle in each cellular of your physique might crumble by way of fact they are all held jointly by utilising the electromagnetci stress which travels on the cost of light. you may exchange right into a surprising and ginormous spray of subatomic debris and heavy accountability radiation that could particularly be a sight well worth witnessing. let us know before you attempt, and we can get waiting for the gentle coach. and that i does not assume that something to do with "replace realities" is an thought. Mad conjecture is probable a greater precise technical term. Cheers!

Below is an answer I submitted to the question "Is time travel possible"? In addition to this, Time, Size, and Mass will all seem normal for those in their own reference frame. These entities would seem peculiar, for example, if earthlings could somehow see (see in another reference frame outside their own) the people traveling close to the speed of light. The Earthlings would see the travelers shrink, become more massive, and notice that their clocks were running significantly slower. The following is a a brief description of time , the 4th dimension. I hope this helps.
Yes, one aspect of time travel is theoretically possible. That is to say, according to Einstein's Special theory of relativity it is possible to travel into the future. How far in the future in a given time span depends how close to the speed of light you accelerate. Traveling at 80% of the speed of light according to Einstein's formula y=1/ Sqrt 1-v^2/c^2 ,(v=velocity, c= speed of light) the clocks on Earth will advance 1.667 times faster than the one traveling in space. Therefore, after a twenty year journey by the space travelers, (20 yrs time has elapsed by the travelers account) upon their return, there will have passed on earth 33.4 years.
At 98% of the speed of light, 20 years of travel at this speed, upon return, 100.4 years will have passed on earth.
This is the equivalent to traveling into the future, which is a form of time travel. Therefore time travel is theoretically possible. In fact, check out this site as the guy proclaims that we will be able to approach speed of light travel within 100 yrs.

Traveling back in time is debatable, as you would have to be able to exceed the speed of light to do that.
Plug in the numbers to this formula. speed of light c= 186,000 miles per second. For velocity, just multiply this number from .01 to .9999. Then just follow mathematical operations.
good luck

I'm traveling through time now!
Seriously, traveling backward is impossible. Forward leaps might be possible.

I don't think it will ever be possible that would allow man to wreck his future and past.
