post if you think humans can or cant travel if you think we can post when you think we can time travel. I think we can in about the next 100 years.

Pretty much proven we can. We already have. But efficently, i think maybe 300+ years. More for going back in time.

I believe you can go to the future but not the past. Discovery channel mumbo jumbo I can't specify why I just remember this special that was on it that brought me to this conclusion. I honestly doubt we will ever be able to go into the past, it really opens a Pandora's Box of possibilities.

It has something to do with the rotation of the earth and if you are in space time moves faster depending on speed. I don't honestly remember all the technical details about it and I wish I knew where the info was on the net. I just remember that asian scientist they always have on the discovery and science channels talking about it.

The man I was referring to was Michio Kaku. I am searching to see if I can find the information.

From some Stephen Hawking program on the Discovery Channel. Like everything, time has it's little raptures and fissures but they are really small, if you managed to make them bigger somehow, the radiation feedback repeating the same momment would make the portal colapse into itself.

Oh yeah, that too, not only the Earth moves around the Sun, the universe keeps moving, trying to get the exact coordinates from the exact place you want to go would be a pain in the ass.

That one scientist, (can't remember his name, he's in a wheel chair) held a time travel party. He let all the scientists know that he was doing it and told them if anyone ever invented a way to travel backwards in time to come to that point in time and space to the party. Nobody showed up so that proves that we never invent it. :)

Time dilation allows different relative progression of time at relativistic speeds

This, you can alter time progression by going really fast,and by getting near to massive objects. This will make the time for you to go slow, thus traveling to the future.

If you travel back in time, you would theoretically change our reality. If that is the case, every time travel has already been done and our reality is set in stone. I think it is more plausible to travel to a different, idk, dimension in time.

I read through this article and it really isn't the best but it does semi explain what I saw on the tv awhile ago. Its written by Michio Kaku and it isn't a completed article. Anyways here you go best I can find thus far

Well, most physical equations (outside of thermodynamics) are time-reversible, but that is a far cry from time itself being reversible Edit: that reversibility is generally a consequence of conservation laws, however

Isn't entropy part of the thermodynamics, I think it's reversible.

Entropy always increases; it's the key physical indicator of "time's arrow", and yes it is part of thermodynamics

Zyrokin
Not necessarily. Some Scientists would state that Time travel to the past could be theoretically possible. Even if you did change the past it wouldn't change our reality but simply start a new reality that would break off from the original. I don't know if time travel to the past is possible or not but it certainly is interesting.

To the extent that one can reach the future in less relative time than someone who has not been accelerated to near light speed or who is not in a near-event horizon gravitational field, sure...

I didn't say it was practical, but it's certainly possible, which is what this thread was asking.

That is sort of what I meant by another dimension in time. We are on the same wave length I think. It is definitely very interesting.

I feel obligated to append "in a closed system", lest we give ammunition to those who invoke entropy as an argument against evolution. :P

Tomorrow is not the same as hypothetical 100 years to the future, maybe politics, technology and the planet itself would be different, maybe the atmosphere now is poisonous, or the country that started the experiment now is on war and as soon as you leave your time traveling ship some country involved will take you as a prisioner, or during the travel your ship goes boom.

Really? Where are you getting this from?

It has something to do with the rotation of the earth and if you are in space time moves faster depending on speed. I don't honestly remember all the technical details about it and I wish I knew where the info was on the net. I just remember that asian scientist they always have on the discovery and science channels talking about it.

The man I was referring to was Michio Kaku. I am searching to see if I can find the information.

Your talking about the TV show called The Universe. That show is on the History Channel, yea I made the same mistake too thinking that it was on the Discovery Channel. :P

Time travel is already on the go all the time. The bigger an objects mass, the more gravity it exerts, which also has a very very very small change on time around it on the 4th dimension. Standing next to the pyramids makes you, essentially, slow down in time relative to those not near the pyramids, albeit not a noticeable change. It also happens every time an astronaut takes off into orbit.

[QUOTE="dragon7x2k"][QUOTE="xaos"] Just as you don't know what tomorrow holds; I don't see much difference

Tomorrow is not the same as hypothetical 100 years to the future, maybe politics, technology and the planet itself would be different, maybe the atmosphere now is poisonous, or the country that started the experiment now is on war and as soon as you leave your time traveling ship some country involved will take you as a prisioner, or during the travel your ship goes boom.

Since time dilation still involves moving through the intervening period, you'd still be able to see those changes occurring :P
