Time travel will never be possible.

[theultimateend]

Because if it WERE, the public would eventually get their hands on it, which means millions of people would have the ability to change history to their will. Now, eventually, some idiot/crazy person/terrorist is going to go back in time to where the first humans were, and kill them, or something along those lines. That would cause a major paradox, seeing as the killer's ancestry line would never exist. So as long as the universe as we know it isn't destroyed, we can be certain that time travel will never be possible, at least for humans.

This isn't the only example to prove my point, there are an infinite amount of possible paradoxes, thanks to the butterfly effect.

Your thoughts on this matter?

Depends on how many decades old your conception of time travel is. If we are looking at what appears to be your view (IE the 1940's) then yes it likely won't happen.

However given the modern views of it it is likely to be possible only because it'll be the inevitable side effect of warp travel. Essentially the distance you would circumvent through warp travel would end up actually transpiring so by traveling in this manner you would be time traveling.

Which doesn't necessarily seem like a positive thing, I know I'm in no hurry to rush a thousand years into the future. Unless Futurama is hard fact.

If at the point of light speed time stops, does light travel through time because it is so fast that it transcends itself?

Well considering that no human being can earnestly visualize with accuracy the actual size of the Earth or Even the moon...or even the size of the United states. Considering that no human can even describe a base color to someone without using an example of it (IE describe Blue to someone who has never seen blue without examples of Blue things and having them visualize it). Taking these things into account, I think its a bit naive to assume that we have all the answers to these questions.

However again just because we don't have the answer to these questions doesn't mean that they are evidence that these things cannot exist.

A Paradox is hardly the end of any question. It just means that the problem isn't being properly looked at.

However if it were up to me to decide. I would assume that while in the process of warping space and traveling in between the two points everything within the warped space would act normally upon entrance, during travel, and once exiting. However technically that light and all things that traveled through that point would now be (relative to the universe around them) X years old. Where X is the distance they traveled in Lightyears.

Travel 100 lightyears and you are now 100 years older than your surroundings while only feeling a few moments older (or however long the warping ends up being).

No, you're all getting this all wrong. See, when someone invents time travel, and shitheads like (insert appropriate politico-socioeconomic demographic here) fuck everything up, someone will always eventually be smart enough to go back in time and stop the invention from being made, one way or another.

And then you get stuck in this timeline. And instead of transcommunicating directly with other peoplebeings using mindlink, you're forced to use a "key-board" to "type" out your thoughts. God, I miss the twenty-eight-thousand-nine-hundred-and-fourth millennium.

How would you stop someone from destroying the space-time continuum if it's already been done? You can't time travel when you're dead/don't exist, so you can't go back and stop the guy from fucking up the universe.

who gives a shit. It may or may not, so what? if it does then it will be relevant.

 

[resultsmayvary]

Time travel is impossible. Delayed aging to "Travel" to the future as you are now will be possible, but there is no going back in time. Time isn't an object, it's a measurement of event's. Things that have happened have happened, there is no parallel universe where events play out on repeat.

That's my thought on this.

 

[Mostly Harmless]

Primer made it seem almost logical, that is if you understood anything in the movie. I still recommend it though.

Let's look at the classic Sci-Fi idea of Folding Space.

In Event Horizon The aptly named space ship does not travel at any relative speed through space or really by any means of distance at all. it folds space and punches through the two folds. If you arrive at a position 80 lightyears from where you existed 30 seconds prior to folding space, are you 80 years older?

For a paradox to exist, a paradox would need to occur, they are self-defeating. You can certainly kill your grandfather, but only because you already have. We are here because of the past, to go into the past is to become part of it. Attempts to shatter the world are, in truth, the very things that make the world. Every assassination attempt on hitler has already occured, and obviously failed, should time travel be possible.

If time travel is possible, then paradoxes are not a concern, they have already been defeated. If it isn't, which is likely, then there is no problem. If it had occured, we would see evidence of other timelines in our own, or be up to our assess in future-men.

All this has happened before, and will happen again.

Ninja'd.

Technically we are all traveling through time as we speak. We just can only do it traveling forward not in reverse. Some theories suggest that a person can travel to another dimension that may be in exactly like ours but just at a different point in the timeline so you could theoretical kill one of your ancestors in that dimension and still exist.

I have a theory that a super advanced form of humans have discovered this and have created computer models that tell them which is the best movie/concert/event in our dimension to go to in comparison to their own timeline in order to buy all the tickets and screw us out if the enjoyment of said event, that's why you can never be able to pick out anyone from an awesome concert at the front rows as anyone you recognize and neither can anyone else.
I suspect they may also use it to figure out when your girlfriend is most vulnerable after you have a fight and seduces her so when you confront her about her cheating all she can say it is "It was just some random guy who came out of nowhere!"

Of course my theories are all but impossible to test but validity and proof is not necessary for the internet.

This in a handful of sentences is what I have been attempting to present to the board over a series of atleast 20 posts.

We currently have no way of going BACK in time, but we can build a machine to catapult us FOWARD in time.
It is actually fairly simple, here is how it works:
First, we build a ship that can travel close to the speed of light.
Then we stick some humans aboard and send it shooting off.
Time will pass more slowly for them, as predicted by einstein. When they return to earth, they would find that a considerable amount of time had passed.
This is the concept used in Planet of the Apes I believe.

I'm a little sketchy on this theory. (I'm an engineer)
I thought that the speed of light was in theory the fastest you could travel?

But yah I have not heard of the de-syncing experiment. Sounds interesting.

Yeah the reason for the speed of light being the fastest you could travel is that your mass goes up when you attempt to go faster, so it takes more energy to cause you to travel faster.

This is a fun theory in my opinion, because then theoretically wouldn't it be possible for an atomic bomb to explode muge bigger travelling at the speed of light than at rest? I have no idea, but It's a fun idea that I thought up one day.

Theoretically it would take infinite energy to make you go the speed of light. But then if you have no mass, there is no energy required. I'm assuming that's why photons are able to travel at the speed of light.


That's why quantum entanglement is so weird, two particles which are separated by a large distance instantly affect each other, ignoring the speed of light. But then the big problem of quantum physics vs classic physics steps in, because our measurements for this are done in classic physics where it doesn't really link in with quantum physics. So we aren't even sure if that's true.

I believe tachyons in terms of time travel have been proven false now, but they were a fun particle, for a time physicists seriously considered it possible that this particle could travel backwards through time, but now they believe it isn't possible (Hell, they don't even know if the particle exists).

But step in Sci-fi geekery which is purely my own weird ideas which are not at all possible, but fun to think up.

Let's say in the unlikely event a particle does exist that travels faster than the speed of light, (like a tachyon) and we invent a way to recreate humans based upon measuring the make up of our body (ok, not exactly easy science, but maybe in a thousand years?), And we figure out a way to produce these time travelling particles, and receive them somehow.

Wouldn't it theoretically possible for us to send/receive these particles in a pattern, so we were able to reproduce a human from a different time through particles transmitted from a different time? Of course it would require the same device on both ends, so it would only work from when we had first created the device, but it's still time travel of a sort.

I believe someone posted a link to an article somewhere on this board about a man who claims to be building a machine that would work in a similar way and have similar potentials.

This is all assuming that events in history are preserved in a "line", where one can go back to past events.

Assuming it's possible, I'm in the alternate universe camp. It avoids a lot of messy paradoxes that tend to arise from time-traveling shenanigans.

 

[Jinoru]

Good thing God is smart Or else your scenario would definitly have happened.

 

[Ultrajoe]

More issues would be resolved if I could devote such comment to every thread. However, WoW proves constantly to be more entertaining.

I can't Pwn everywhere, try as I might.

 

[TheLastCylon]

I always thought that time would find a way, like if you kill your grandfather in the past, the timeline would compensate for it.

Your thoughts on this matter?

You don't understand time travel because if u did u know that when you travel you split our universe into two. one with the changes of time travel and one that keeps going as if nothing happened until it keeps repeating like this http://www.samplewords.com/docthumbs/homehttp://www.samplewords.com/docthumbs/home-tournament-16-thumb.jpg
Basically i am a time Splittist and into that thoery
