Time-travelling - possible or not?

One of my favorite time travel films is "Somewhere in Time" starring Christopher Reeves and Jane Seymour. It was such a delightful movie. I truly wouldn't want to go back in time or forward for that matter. Life is hard enough just dealing with the present. I couldn't imagine dealing with more.

I certainly would love the chance to see what my future will look like as I'm tired of second guessing if I'm doing the right decision and thing at the moment. I tried to take everything in stride. It is difficult to decide for your future alone. We both know to travel through time is impossible to happen. Unless, a miracle will take place and we were all granted that a 5 minutes glimpse into our future.

Time is a man made concept and it would be quite impossible to travel through it. We have all seen and enjoyed many films and television programs which employ the idea of time travel, but this would require the existance of all levels of time at once.

yeah...it would surely be possible in the future...and it will be me who will invent the time-machine Lol!...but then im not sure whether the machine will bring u back to the present time!!!hehehhee...so beware!!:P

Time travel has already been achieved............sort of. Two atomic clocks (the most accurate in the world) were used, one was attached to a aeroplane or a shuttle that went into space (cant remember exactly) and the other clock was left here on earth. I think the experiment lasted for a few months or something like that. Anyway when both clocks were bought back together the clock that had been up into space was half a second or one second behind the one that had remained on earth for the duration. That did happen, i may have got one or two of the details wrong but it happened.

Time Travel backwards is IMPOSSIBLE! Lets say that one day there is a cure for cancer and at this day there is also time travelling technology. A man travels back in time and Stops cancer from ever existing (how he does this i dont know but lets say he does) this stops his grandfather from dieing from brain cancer. BUT THIS IS IMPOSSIBLE, becuase if time travel was possible cancer wouldnt have existed BEFORE the man travelled baack and killed cancer...not a funny exemple but is what my boyfriend said to me...:)

I most certainly think that it is possible, possibly even within my lifetime! Science and technology is developing at such a rapid pace these days! Computers for example, are such powerful machines, compared to what they were less than two decades ago! With the unbridled human inteliigence and technological development, I say time travel is very much possible.

Travelling back in time is impossible. There are talks of if you found a worm hole that looped back on itself, which is extremely hard to find even if they did exist. But there is also the theory that you can travel forward in time. If you travel at the speed of light (fastest possible speed) then the world around you would be travelling faster than you, so the world would age quicker and you would be the same age. But that is also fairly impossible considering the space you would need and the forces of getting to that speed.

I have been thinking and obsesing about this every since the days of Back to the Future one and the show Dr.Who. I have thought about all the paradoxes and how to get around some of them. I think for the most part I would make my family rich and then just go back and observe things. Find out if something really happened and why it did. Like the pyramids and Stone Henge, and what really did crash at Roosewell.

Personally I think it is possible. However I don't think we could change major things within it. To me time is like a giant river. Going backwards in it might cause ripples within it but it won't change the course of the river over all. It would take something very major to do that and I don't think that would be possible. I think the river or time is too big of a force to try and alter to any great extent. If we could go back we might be able to change minor aspects of it. Little things but over all effects would still happen.

It's another one of those things that no one can fully contradict nor support. Personally, I have no idea if it's possible. A lot of flaws have been pointed out in it but if you look back.. many were laughing about people trying to invent what we have today. Electricity, planes, phones, computers, internet. It looked like something completely impossible 200 years ago. Look where we are now..

I guess your right, time travel present interesting things that might amuse us or even scare us. The thought of one self having a miserable life in the future is unacceptable to every human being. Buy hey, anything's possible right now. I remember watching the Batman TV series when I was a kid (Adam West as Batman...), how cool it was to see them using their "bat phone" while driving the "bat mobile". As a child I knew it was not possible, little did I know that in a span of 20-25 years, almost every human being on earth has a cellular phone. I believe that time travel will be the coolest thing that will hit mankind, we may not have it in our lifetime but given the advances in technology we have today, who knows, our great great great grandchildren might have the luxury of visiting their parents in their youth someday.

I think I would like to go back to the past and I would do a few things in my life differently like. I would of gone to college and gotten a good education. I probably would have avoided a few things people and places in my life also.

Well, movies such as those Back to the Future series and Time Cop surely fired up our imaginations. After watching BTTF over and over, my youngest son (he's 8) is now dreaming of becoming a scientist someday. Ask him why and he'll answer you with "Because I'm gonna invent a real time machine!" and that said with confidence :) But me, if ever there would be a time machine invented someday (by my son? hahaha), I'll be too scared to explore either the past or the future. Sure there are things I'd love to change about my past but I believe that those experiences happened for a purpose -- to teach me a lesson and make me the person I am today. As for the future, I don't think I'd like to know yet what I would look with wrinkles all over and with a head full of white hair :p

In the future, I can imagine time traveling being possible...just don't ask me how. Just think of all the things that have been invented in the last 100 years; things that everyone thought would always be impossible to invent. If it ever became possible, I'd like to visit my parents and grandparents when they were younger and see how different life was then and what they were like. I'd also like to visit the future to check and see what my grandkids grew up to be like and what kind of great-grandkids I had.

Personally, No I don't think time traveling will be possible in the future. And I wouldn't want to travel to the future anyways..I like to be excited about whats going t hapen..not knowing...if you know everything that is goin to happen in your life...what is there to be excited about waiting for the nxt day to arrive...or hopeing you get another day of life..... But then again, I never claimed to be right about everything either.

No! It is just our fantasy. I would love travelling back time, though. But I believe that we can't do it. It is a reality that we should accept it. Because God has set-up the time table. He created Sun and Stars so that we can know and determine time. As you can see, our Earth is getting older and older and it will finally erode. The Earth can't go back with the same condition when it was created.

I doubt it...If you were to travel say, 30 years into the past...YOU would also be 30 years in the past meaning...if you were 3 years old back then, you would be 3 years old once again... you would never see another version of yourself because if you turn time back 30 years...the "other you" would not be in existence yet, so there would be only one you. Plus, you cannot change history.. everything that has happened, has happened for a reason. There is a purpose for everything and trying to change that would be impossible. I will agree its really cool to think about though...just not possible..

yes, if you could build a device that could reach a certain speed that is faster than the speed of light.. but i dont want to travel to the future i'd prefer to have more surprises and try to face all circumstances that will come.. besides GOD granted me the courage to do the things i can, the serenity to accept the things i couldn't change, and wisdom to know the difference..

I would say yes, it can, but only travel to the future but not to the past. Just think about it, when you go back to the past, any action you have done will change the future. Action as simple as moving a stone may make the future totally differnet. (For example, when you move the stone, a man step on it, fall and then die...) In this sense, the future you are in is no more exists. Some people talk about the concept of parallel universe, but I am not really agree with that concept.
