Why I think time travel into the past is impossible

I was watching a episode of through the wormhole about time travel and was thinking, if we really did develop the technology to go back in time, wouldn't we already have seen people from the future at some point in human history? Even if the future civilization deemed it a capital crime to time travel back in time, you know there would be rebels who would go back in time if it were possible. Or maybe there is time travel and the government has it under wraps or something, how else could they plan a more perfect scenario where our rights are stripped right in front of us and we bend over and ask for more, and how could they have so successfully had the foresight to implement the credit score system effectively enslaving us to labor? The government in my eyes is a slow stupid animal, no way it can plan the shit we're in right now... woah I'm too stoned stop typ

Until we can propel ourselves at multiple times the speed of light without disintegrating, doubtfull it could ever be achieved.

Helluva concept tho....lol

I would be happy taking a 300mph funny car for a spin, its got to feel pretty close to time travel...lol

Peace

There are worm holes all around us and they can take you back in time. Going into one is dangerous though as you can adversely affect the future or one possible future. Additionally - you could possibly meet yourself which would cause a warp and possibly a differentiated thread outcome. This new thread can cause multiple histories/futures to coincide and create virtual cracks in the universal time 'continuum'.

I think some people think it makes them cool and out there or at the opposite end of the spectrum, an über intellectual, to believe in time travel. I mean think about it, just going back one minute means I'd have to type all this shit backwards involuntarily along with every process of every fucking thing existence simultaneously. Depictikn if time being frozen is simply STUFF being frozen and a nice visual of the second hand on someone's magical stopwatch stopping. If time froze that traveller would have to freeze too along with the orbit of the sun, planets and the stars would stop burning. 'Back in time' isn't a place to go to per se, people are going to have to be un-born and shit like that. I don't think going really fast would constitute skipping time either. Maybe itd be considered a skip in our methods of quantifying time but it doesn't mean stuff happened before it.. Happened. I understand people need to push the boundaries of possibility, ask questions and expand their minds but on /this/ one I think people are giving themselves a headache for all the wrong reasons

Live now for now.

I was watching that show today too. It is a far-fetched notion, but as the show was saying, there are certain things done under certain circumstances, that would allow someone to call themselves a "time-traveller." Just not in the sci-fi way we've all been exposed to. But, the actual sci-fi method of time travelling still ignites the imagination, and the fractional possibility of something like that existing in this lifetime excites me. I don't try to make myself cool or place myself at the opposite end of the spectrum though. However, I am an optimist. I like to think that something remotely close could be developed. And honestly, there's been a lot of stuff developed in the past 3 or 4 decades that you won't ever find out about. You may hear a sliver of information revolving around them, but you won't get any further. For example, during the Reagan administration, they pursued and completed the Star Wars program. Which is an array of satellites in orbit that are armed with direct energy weaponry to protect us from incoming ICBMs. So, no, I don't try to fit in by choosing different theories to accept, or discuss. And there are endless possibilities behind every idea or theory that comes our way. I just like to think about them.

Um, yeah it is true many ideas borne of science fiction have become a reality but I bet it was because propel then know those particular idea werent theoretically all that outlandish, they just lacked the technology. I mean, tablet computers could have easily been around decades ago of the technology made them economically viable to mass produce. The actual technology is not that new. There is a world of difference between time travel and a satellite defense system.

You've happened upon one of the foundations of Niven's Law.

"If the universe of discourse permits the possibility of time travel and of changing the past, then no time machine will be invented in that universe."

Basically ... if it were possible, we'd know about it. We don't. So it isn't. cn

Well that's a rather obvious difference. I wasn't comparing them to one another. I merely used the Star Wars program as an example of futuristic/sci-fi technology that has been around, but unknown to the masses. Direct energy weaponry and time travel are both sci-fi/futuristic technology that many people still don't think are remotely possible. But if you can create one of them (Star Wars), what's to say that in the future, time travel couldn't be one of those technologies? I'm just thinking about different things that are precursors to time travel that already exist today. And in reality, though actual time travel like Quantum Leap or Back to the Future may never be real, it's still not a definitive "No" or declaration of "impossible." And though some of the technology isn't new, it's not that old either. It's taken years for computers to go from being the size of a basketball court, to the small sizes today in tablets and cellphones. I would hate to be around the era when someone's tablet was the size of their house.

Who do you guys think the aliens are. It is us.
Did we learn nothing as a people from Bill and Ted.

Sorry nope. There's 101 space age invention concepts people scoff at that I DO believe could be made a reality but you realize an invention like this isnt about building something for purpose, but making the entire fucking universe work around it. Undoing the entire universe's processes isn't like developing computers that can read your mind, lazer guns, or even a telekinesis headset... Something along those lines. Even if it did work I think you'd be stuck in the past after one trip... Where the machine doesn't exist yet but the past isn't a place so YOU as YOU couldn't travel there anyway. We need a machine that undoes the universe? That's going to make me barf my coffee back into my cup Honestly, I am usually the first person to say 'wouldn't that be cool, why not?' But on this one??? Ok, I will back out of the thread and stop pushing my opinion.

Opinion well stated. I was just saying that even though it's hardly possible, it would be pretty kick ass. And that there are other technologies today and theories, that people at one point, said, "you're fucking nuts, it's not going to work." And whaddaya know? They exist today, or have substantial evidence to prove it more than a theory. And I think that if they made time travel possible, it wouldn't be some epic machine that would destroy the fabrics of space and time. I believe it would be some sort of device that acted as a wormhole. I doubt that would be anymore devastating than the wormholes that already exist in the universe.

From what I have read, if you were to be able to time travel, if only for a few minutes, when you came back, everything and everyone you ever knew would have already been long gone, not sure what the theory is behind that, but I guess anything would be possible at that point...lol

On a side note, I have smoked some bud that made me think I had done a bit of time travel, bombarded by endless deja vu makes the mind think of some weird shit..lol

A form of human time travel has already occurred, not as dramatic as the Hollywood stories and yet it happened...

"The probability of a macroscopic object--like a human--doing this trick is infinitesimal. But thanks to Albert Einstein we know that time travel of a different sort does happen in the macroscopic world. As he showed back in 1905 with his special theory of relativity, time slows down for objects moving close to the speed of light, at least from the viewpoint of a stationary observer. You want to visit the earth 1,000 years from now? Just travel to a star 500 light-years away and return, going both ways at 99.995% the speed of light. When you return, the earth will be 1,000 years older, but you'll have aged only 10 years. I already know a time traveler. My friend, astronaut Story Musgrave, who helped repair the Hubble Space Telescope, spent 53.4 days in orbit. He is thus more than a millisecond younger than he would have been if he had stayed home. The effect is small, because he traveled very slowly relative to the speed of light, but it's real."

I'll read the rest of this later because I'm at work, but the thing about time travel is I believe that it is actually"impossible". or what we know to be impossible. I think the only way would be to go to another dimension completely. One where all the things that the time warp effects are accurate in relevance to the alternate time skew that you created.

For instance, you tell people you time traveled, they'd have no way to believe you since things were like that anyway. So it's impossible still.

There's a way God dammit, but were far off.

Plus time travel is risky. I think only certain people could do it. Ones who were professional enough to not Ruin everything. I bet how to make one is far out of any normal citizens grasp.

Its all a matter of perspective. Time slows down for one thing from the viewpoint of other things. GWN's post is still really cool.

Like superman flying around the earth before you can braw your next breath.. but it's not the clock going backwards. but time could appear to stop. Our perception of time, how we attempt to quantify time. I want to watch Heroes now..

I would suggest that relativistic time mismatches don't count, since both environments are still going forward in time, i.e. time remains monotonic. Even extreme relativistic effects cannot engender a reversal. cn

What if you need to have invented time travel in order to go to that time period? For example you can create a wormhole that allows time travel, but you didn't create it until 2015, so any time after 2015 you could return to any point in time dating back to the creation of the worm hole, but not before. That would allow time travel at some point, and would explain why we aren't inundated with time traveling vacationers.

Also what if time is an illusion? The past, present, and future all exist simultaneously (whatever that means in this scenario) and our experience in life just gives us the illusion that time is passing. Kind of weird, but what if we have no real fundamental concept of time because our experiences color our view of it so drastically?

I think if I eat one more piece of hash candy I just might achieve time travel.

I traveled forward in time and it's crazy cool - you can buy Pot at Wal-Mart!! It's right next to the beer!
