The possibility of time travel

The possibility of time travel

Little things resolving into big issues, easily fixed by the possibility of time travel.

We could go back in time and stop those who did wrong, imagine the wars to stop, the people we could save, the diseases to heal, the persons to talk to and so much more.

Time is a complex thing; it is not just as simple as ‘the name of aging objects’.

What do you think about this subject? Do you think we will ever succeed in travelling between time dimensions, going to other places, changing the present, protecting the past and visiting the future?

What are your theories and do you believe those theories, including the ones of many famous people, like Albert Einstein for example.

How could we do this?! When could we do this?! Where could we do this?! I hope we can solve, no, discuss these things here and many more.

Do not follow others; go for your own belief. Say what YOU and only YOU think is right…

I don't think anyone can change time.

I think that if a person travels to the past, then there presence had always been in the past - take J. K. Rowlings theory of time as demonstrated in the third Harry Potter book. Harry and Hermione traveled through time and saved lives - but those lives had always been saved. The events that took place during their travel took place when they had experienced that time period before, such as Harry saving himself from the dementors.

I'm really bad at explaining this, but it makes sense in my own mind. Basically, I don't think time can be changed. Time is Time - it all weaves together into one pattern no matter how much mucking about with it people might do.

Otherwise, there would be infinite numbers of alternate realities tangential to our own reality here. I exist now - but if someone traveled into time and, say, killed off one of my great-grandparents before I got a chance to be born, then I won't exist anymore - and my existence is in a whole different dimension, almost.

Of course, the above story could be true.

But I prefer to think that everything works together to create Time as one entity rather than infinite entities, that the universe has only one story.

I think the thing you are talking about is that everything is already decided. We can change nothing, EVERYTHING is already decided. And that EXACTLY what I thought a week ago. Even my nickname on msn was 'We will never be able to travil in time, since the future dos not yet exist'. I was SURE there was only one time, this one dimension we live in, one universe, one galaxy, one world. And... I was wrong. Somebody even told me that, yes indeed, time travel is already possible. He told me lots things and to say it in short: If we could just go fastar as light, we would be faster then material itself, so we would be uneffected by time and so we would be able... to travel in time.

I'm not saying that we won't be able to travel in time - I'm just saying that we can't change the past. And I'm not saying everything is already decided either - I'm saying that we can change the present with ourselves and work toward a bright future - but there's no "undo" button. That to shape our world, the only time is the present.

I think time travel may be possible, but I think that whatever people might do in an era not their own will not change what they know as history but in some way contribute to it.

I'm not so sure about how it might be done, though - to travel faster than light would be to travel faster than material itself, but I don't think that guarantees time travel. Even if we travel faster than light, we still maybe material ourselves and be completely affected by time. Or to travel faster than light might destroy us completely so that there's no one to travel in time anymore; anything could happen. We simply do not know what would - the speed of light, as far as we know at this point, is the speed limit of the universe. (My physics teacher had a key chain that was a road sign - Speed Limit 186,000 miles per second. ^_~)

No, we will be able to travel in time. We must! You know humans, we are much to curious to just let it pass. All we need to do is get a speed of 300,000 km a second and fl00p. And I get you when you are saying 'But that dos not assure time travel'. Well, then WHAT are all those famous theories about?
I mean, you just CANT ignore them.
And you said 'We could explode' or something. But think about that. That is just simply guessing, I mean, if you rely on guess's... then we just shouldn't try at all.

Ruben, just as a bystander...how much do you know about Physics and Quantum Mechanics? Just curious and all as I want to know where you're coming from.

I must admit, not much, if any at all. I'm only 13 but that doesn’t take away my rights of believing in such things. And the things I have said until now are all hypothetical, and I'm not even sure if humans will ever succeed in getting such a speed... But still, a lot can happen.

Again, I'm not saying that we won't be able to travel. You're completely misunderstanding my ideas. (But that could be due to poor explaining as well.)

As for "just guessing" - heck, as far as I'm concerned, Einstein's guess is as good as my own. Obviously all those scientists know a lot more about physics than I do, but when it comes to the unknown and unexplored, everything is just guessing. Guessing on evidence, but guessing all the same. Much that we believe about the universe is just calculated guesswork.

Where's the proof that if we start traveling faster than life that we'll travel in time? Give me the specifics. Really, I'm interested, if you have them. What's the evidence behind this theory that time overlooks objects faster than light? It seems like it's just as much guess as my theories are.

I can not begin to explain it all as that person did to me. I indeed used to think 'Why would we travel in time if we were faster then light, why is light THE thing we msut exceed?!'. But the persons who know what I'm talking about understand that it almost is impossible to explain...

I don't think time travel is possible. Why? Well, picture this.

You go back in time. You screw up time. You end up so that say, you were never born. Then how did you travel back? There was no you to ever travel back, so you can't possibly be there.

I love the Donnie Darko theory on time travel though, with all the tangent universes, and how he had to die in a tangent one to save the real universe. A really confusing film, but it's got so many layers. You'd enjoy it even if you didn't understand what was going on. *steers self back on topic*

So yeah, that's why I think that.

Donnie Darko? I also saw that movie, with that rather weird bunny, right? Well, I admit, its much easier to not think about it, but I must. And your example, of never being born... Well, some say the whole universe would collaps, but I'm not such a pessimist... I think that nothing would happen with you. Because you must not think time is one line, no, it is divided, if we would time travel we won't magicly go back in time, no, we would go to another dimension. But do not see it as digimon, because the dimension is still the same, but whatever happens in that dimension dos not inflect anything on the present in another dimension. It is hard to explain but I hope you can see my point.

I agree with Tracy on this one. I remember a debate on the Harry Potter thread. There was an infinite loop thing that kept popping up.

Say my friend is killed. A week later, I go back in time, and save him. Then, a week later, we'll both be fine, meaning that I have no need to go back, so he ends up being killed again.

I didn't explain it very well.... I like the way JK explains it in the books.

How does anyone know what you're talking about if it can't be explained?

I hope I'm not coming off as rude, but I'm really curious as to how this theory works. I would love it if you could at least try to explain it to me - otherwise, I will have debated about something no one seems to understand.

Ow, I haven't even begon to start my own theories, now I'm just overlooking the most famous ones around. Soon you'll get to know my perspective over all of this I'll be quit objective in the beginning, but in the end... Nothing will be able to stop me, lol.

Its very very very late in Belgium right now and my brains can't function, so I'll continue this, if you don't mind, tomorrow.

Well, technically, we are always travelling through time... time is always moving, and we're always moving with it.

The time travel that you speak of, though - WHY would we want to change things? All of those ancient wars and events - as horrible and brutal as they may be - are what has created our world, and formed each and every person. We have been changed by World War II and always will be. We have been changed by 9/11 and always will be.

Take it away, and we're completely different. We haven't seen the hardships that made us strong, the grief that united us.

And since we would be weak and divided, some other problem, possibly something worse, would take place. It wouldn't solve anything.

I think that if there is an issue now that you wish you could go back and change, maybe you should focus on how you CAN change it now. The present is as much an opportunity as the past. Why go through the trouble of changing the past to fix the present when you can change the present to fix the future?
