Time Travel - An Impossibility? Is time travel possible? Will we ever manage it? What are the dangers?

..."Happiness today is the anticipation of tommorow"I agree that we might only be able to go forward in time. Despite the fact that it would very cool to see what lies ahead...wheres the fun in that? Why would I want to go forward in time to see what ruins my day tomorrow? I'd rather just find out what ruins my when it happens! That's the fun and amusement of it!
By the way, I love how this turned into, "can it be done?" to "why would it be done?"


If I could travel in time I wouldn't go forward a day or two or ten or twenty years! I would go 100 years or 200 years into the feature. Maybe even a thousand years. I would like to see not my future, but everybodies future. I would like to see what happens to mankind and to this planet. I would go for the long run... That would really be interesting, not my "tomorrow" future. I will live to see tomorrow, but I won't live a thousand years... Maybe I would go forward even more then a thousand years - like in "The Time Machine" - to see how we will evolve or who will replace us as a species.

If you're asking me, time goes to one direction only, and that's an impossible thing to change. You think you would be able to visit yourself in the childhood one day? Think again. If you would of done that, you would of have already lived it(you would remember some older man saying weird things while you were a kid). But, maybe some day...

I think time travel could be possible, but maybe somewhere in the future, lets give it 1 million years. By then, humans would probably move on to other planets, other galaxies, who knows?But there are many laws of physics and science that are preventing this from happening, for one, time is moving at constant speed. I dont think you will be able to step into that dimension. Lets say if we do. We will probably be stuck. Yep. Lets say if we do travel there... how are we going to get back? Anyone ever thought of that?Also, lets say that we do get to travel back in time. and we do get stuck. Who would know if time travel was possible? The only way to do that is to contact to the future, in which you cant because that technology does not exist now. All we know is that we, humans, know that we are in the present in our perspective. Maybe something out there DOES exist, and maybe its present for them but future for us. What if a rip in time happens? Anyone ever thought of that? What if we form a blackhole just because of 'trying' to get to the past, or the future? That would be quite possible. Also, wouldn't there be laws on this sort of thing? Even if we had the power to do this, wouldn't we stop anyone from having the power to do this? Is this the right thing to do? Is this what god wanted us to be able to do? I say no. Destiny is destiny, time is time, and every living creature for the past whenever has had to put up with past, present, and future. These are one of the things that we aren't ment to do.So, lets say that we do... we can travel back in time without any problems. Peple can travel back and forth. What about those who want mass chaos and destruction? What about those who want to have all the power? Wont they get a hold of this technology? You bet'cha. They'll be the first oneswho will try to have this technology for their own good use.

"The Time Machine",I like this movie!hehe!But,i think time travel is an impossibility.If it come true,the world will get ball-up.If i do something bad or feel not good,i could go back to the past,and do it again.It's just a joke,or a fantasy.I think so.People should work hard,and not fancy such thing.Just my opinion,hehe:)

Time Travel....Time Travel - An Impossibility?I thought you might be open to read something that I have read a couple of times. Its about a self proclaimed "time traveller" named John Titor. The link I am putting on here is from 2001 (a few months before 9/11/2001). He was only on line for a year I believe.. Something I found interesting about this person was that these forums were removed completely, we the public only have access to it because people had saved copies of the discussion on their computers.Its a long transcript but very INCREDIBLE... Some of the things he talks about are happening right now...Heres the link :http://www.anomalies.net/did-a-former-coast-guard-sailor-have-an-encounter-with-humanoid-creature-or-a-human-breakways-autec/ love to hear what you thought about this...Peace Love and UnderstandingKells

I do not believe that time travel will ever be possible to any human IN our solar system. First, I question how it would be possible to do it. You can ask a scientist and he/she will probably be puzzled.If time travel is possible by traveling at intense speeds faster than light would just incinerate human beings or animals in a matter of microseconds. I have no clue if there is life outside our solar system but I do believe that maybe living things will have unique qualities like crazy resistance against physics beyond imagination. Keep in mind that the universe is as big as how far light has traveled and is still continuing. This may sound crazy but it’s “me” logical. For other people, its probably, not logical at all.

Ok, where do I start.First I guess that time is the 4th dimension. I think in general this is true but not quite as most people understand it. The idea of time and history as a simple dimension similar to length, width and height doesn't really make much sense. If this were the case then we could find some way to move along it (aka time travel). The big problem with motion through this dimension is that you are already occupying it. If I were to give myself momentum in the negative direction of time I would run into myself instantly. If we imagine what our bodies would look like if we took this dimension into account then we would be long snakes that occupy every moment along the dimension. Because of this fact I do not think history and future are really part of the dimension of time.More likely is that the dimension of time is almost like a rate of change dimension that causes the basic laws of physics to vary in strength. Take an atomic clock, it has been proven that they run faster in space than they do on the earth. This is because of the distortion gravity has on all dimensions including time. We may say time has been slowed but really what has been slowed is the break down of the caesium particle. I would also imagine the speed of electrons orbiting particles has been slowed, electricity would run slower, our brains react slower, basically everything. If we were to extend this effect to the extreme and pass the point of zero motion then we would get inverted motion and inverted effects, effectively running things in reverse. But this would only be localised and as the system is unlikely to be identical as it was when created the past that is moved into will unlikely be the same.Take for example your want to travel back in time, you decide the best way is to run the entirety of the universe in a reverse direction. First you would have to be outside of this reversal otherwise you would be taken along with it, forget everything and probably leave the universe reversing forever. So you sit outside the universe and watch it start to reverse, then things start going wrong, things that happened before when you were part of the universe now would not have happened, basically the universe would be rewinding as though you were never there, but it still ended up in exactly the same place, this would be some kind of paradox because your friends and family would know of your existence but no one would have ever seen you or ever have been effected by you.Ok, so sometimes seeing time as a dimension is a little boring because it doesn't really fit as a normal dimension as simple as space. Lets imagine that time travel is possible, you can go back in time and exist in the past. Can you change it. Here are my two thoughts on this:1- No, basically what has happened always happened, you travelled into the past and killed your granddad by mistake? Guess what, it wasn't really your granddad, he had his sperm frozen, or you are medically insane and had always just imagined your grandfather when you grew up. Basically with this notion is there is one time line and you cant change it, not without messing with your head. There are some interesting things you can do though. "What you don't know can't hurt you" - if I travelled back to medieval england and killed king arthur well some would say I have changed history, except that I don't know how king arthur died, so therefore what I did could have always been the case. The invention paradox is still possible - if I travel into the future, find a cool device and take it back without finding out who invented it, then I am free to invent it.2- The other most widely notion changing the past is that it creates alternate realities/universes. Well firstly I highly doubt the act of travelling back in time has a side effect of duplicating the universe unless it is a phenomenon that is reasonably common. It would also mean that in travelling back to the present there would either be a duplicate you because the change would mean it was unlikely you travelled back at the exact same time if at all, or you wouldn't exist at all, and if you went back far enough then no one you ever knew would exist either. One of the theories that supports the multiverse is that a new universe is created at every decision point you ever made. But since thoughts are related to collisions of particles and how they interact using quantum physics to determine what could possibly happen then at every collision of every particle an infinite number of new universes are spawned to create every possibility. This seems way to big to be possible as the multiverse would exponentially grow in its already infinity.This probably turned out to be very long, but id also like to quickly add that time doesn't stop at the event horizon of a black hole. The event horizon is the point outside a black hole where nothing can possibly escape. At this point not even light can escape the extreme gravity. The point where time stops I think is actually at the singularity itself.

In my opinion, time traveling is impossible. However, I think dimension traveling will be achieved one day, which would allow us to fix things in different dimensions. Parallel worlds where the things have happened, are happening or haven't happened yet. Yet another theory I've read about is that energy beings are not affected by time therefore if we managed to transform into an energy being and get "affected and unaffected" by time AT WILL, it could then be possible.

When the current Doctor Who 'regenerates' the next one will be played by a 28 year old actor. The first Doctor Who had a grand-daughter with him. So when the new one appears next year it would make an interesting story to have the two meet again. The grand-daughter of the 28 year old will be 69 years old. So is the grand-daughter a Time Lady or not?

The problem with alternate dimension theories is that it requires that every single choice or possible difference cause an alternate reality to be created. That means at every single moment of every single day billions of new realities would be created by the billions of people on earth. To traverse such a dimension would be impossible because each branch is a new direction to travel. Also decisions aren't binary. in other words each decision you make isn't a 'yes' 'no' choice, all the choices in between the extreme choices that could be made are possible.The other problem with this theory is questionable choice. Lets say you are angry with someone you know. One choice is to let it go, and ignore it. Another is to get pissed off and yell at them. Well in this theory all possible decisions play out in alternate realities. But I would never choose to kill the person, but thats a possible choice that could be made. Just like I might yell at them, it all depends on what previously happened in the day and so on. In this way I don't think that multiple alternate realities exist. They don't really make a lot of sense.

Exactly. What you bring up is kind of like the movies Butterfly Effect and Butterfly Effect 3(I don't remember the second one very well).

In case you haven't seen it, it's about a guy who can go back into the past to see things that happened and can change his actions to have effects on the future. He could go back and say something different for example, and wake up in a completely different life than he was in before.

Things like this are entertaining to watch but to think there's even a remote possibility it could happen is too far off in fantasy land. I think a lot of people wish it was true so they could fix things they did wrong but if you think about it, what you did wrong put you where you are today. Every mistake you make teaches you something new. In the movie, for example, every time the main character(there's two...different ones in each movie) changes an action he did from bad to good it causes negative effects to not only himself but those around him.

The movie teaches the view that you should "leave the past behind." Or "keep moving on and don't look back." Those who keep wanting to re-do things they've done already have no idea what kind of consequences would occur due to having made said choices.
