Hey guys does anyone have any thoughts on time travel? Like if you went back in time would that mean you would grow younger, and how do you really classify what the past is when you travel back? Or do you believe in alternate dimensions? But how are they linked?

You do have quite a complex question and there wouldn't be just one right or wrong answer, at least not until time travel would be invented which in a way should never happen.

I definitely believe that Time Travel is possible, but like Juselius mentioned, if you were to use a Machine, chances are you wouldn't grow younger upen the completion of your Journey, as you are transferring physical data. However, if you did use some sort of mystic force to travel, I think you would still not revert in age, as your probably only traveling spiritually, and not physically, and as far as I know the spirit doesn't age.

I've never really cared all that much for the idea of time travel, nor is this a piece of science fiction I've put any study into. From a purely philosophical stand-point, it's a tremendously depressing idea. Like Juselius said, we learn from the mistakes we make and if we can just go back and change it so we did nothing wrong, life loses its meaning. When it comes right down to it, humans are inherently flawed creatures, but as far as I'm concerned, this is a good thing. It's what separates us from the perfect beings we write and dream about and that's what makes us unique. If we become perfect, what reason do we have for emotions like love or hate? The answer is easy. None. We wouldn't even consider them, considering that if we were perfect, we would have nothing to question, nothing to feel. Because emotions, in and of themselves, are flaws too. So, perfection is overrated and ergo, time travel is, as well.

It might be possible, but should I live one thousand years, I doubt to be able to see the phenomena take place. So worrying about it's silly. Time travel won't happen for a very, very long time. But, if it is ever created, I hope its creator would have the common sense to destroy every shred of evidence that he ever accomplished anything. Otherwise, he's damning mankind, potentially leading us to a "slaughter" of sorts.

I'm flawed - heavily, at that - but I'd rather be that way, so I can have the right to love a girl, or hate destructive concepts such as this one. So yeah. better to be flawed and happy, than perfect and emotionless, dead to the world. For sure.

Aaah, a truly interesting topic. Time travel is one of the greatest dreams of man. Yet the question whether it is possible or not is truly a great one. The ability to go into parallel planes of time has often been debated. The only problems are to achieve the speed fast enough and the grandfather paradox. Theoretically, if you get nearer and nearer the speed of light, time dilation ocurrs, whereby your time and the surroundings' times are differant, going 'back in time' as it were. However at this speed your mass is infinite and so is your density. This causes quite a large number of problems. Also a paradox ocurrs. If you for example, kill your grandfather, you can not exist, whereby you cannot go back in time to kill him, and thus the fabric of space time is disrupted.

I don't know...I'm really big on science and the unknown. I think that there are millions of things that are beyond our wildest dreams today, but would be a major possibility down the line. As far as time travel goes? We've been studying it for so long, fascinated with novels like Time Machine, that we've made huge breakthroughs since that time period that lead me to believe we are right around the corner from time travel. We've proven so many theories that all we need to do is perfect them. Isn't science just fascinating?
