We use the word time to measure the aging of life and the things on earth. At least thats what ive been told, but basically it is all biased because of the planet we were all born on. I guess if you were born on a different planet with a faster/slower rotation then you would have a different concept of time and different ways to measure it but as it stands we use it to divide up pieces of the past, present, and future to stay organized.

Good, so we've all agreed you cant Time Travel like Marty McFly.
If time is just a measuring tool we use then the idea of time existing is off. I however, cant help but think of what the Bible says in Revolations "And there will be time no more" Last edited by MixMasterLar; 01-9-2007 at 05:06 PM.. |

Ooh interesting, there was an article in New Scientist about time travel a while back. And while it wasn't about humans time travelling, neutrinos time travelling is still pretty impressive. The article is online but unfortunately you have to subscribe to New Scientist to read it and I subscribe through school so don't have access to the online issues which is annoying or I would tell you the basis of the experiment, it was in September or something so I remember very little...
but you might be able to google it, they're doing it at Fermilab Grr im angry at myself because I can't remember it... but basically they had devised an experiment where neutrinos fired from one side of the world could reach a sensor at the other side of the world before they had ever been fired... However it said at the end of the article that although technically it could work, it probably wouldn't because most physicists believe there is a fundamental universal rule that prevents time travel |

The rate at which we base our time system on is based upon the roatation of the earth. Time itself wouldn't speed up on a different planet, just the rate in which it is measured (that is if they measure it based on the rotation/revolution of the planet, like we do).

Really Jokee? its my favourite magazine...ever... because I'm cool like that
MixMastarLar, I tried googling it and there is very little information apart from the New Scientist website but maybe you'll have more luck than me, I didn't look very thoroughly |

I don't really have time to add much to this right now, but I think some of you may find some value in looking up time dilation, block time, and relativity. None of it's gonna claim that you can definitely go back in time or anything, but if you're unfamiliar with the stuff you may find it surprising and fascinating (at least, I did when I first learned it).
It may break you out of the typical commonsense perception of time, which is really necessary if you want to think about this more like today's physicists do. |

"Turning back time" is impossible.
We would need to build a machine, or do something, that would "remember" the past, and then move everything in the world to the place it was before. Impossible >.<

Time is considered be some to be the "fourth dimension." ((Madeleine L'Engle, "A Wrinkle In Time", yes?)) We have length, width, and height, but our lives take place upon a consistently moving thread: time. Without time, we have no movement, no history, nothing. So technically, time travel would basically be breaking that "4th dimension." And, in all fairness, we cannot really "break" a dimension, therefore rendering time travel illicit through the laws of physics and matter. |

Well Madeleine L'Engle sounds like a very very stupid man.
Thats like the most generic fake descirption ever. |

Time does exist, I dont know what it's made up of but something has to be keeping us moving to the future. Ok the way I wrote that sounded lame, but it's something like that. |

I'm guessing the concept of time as a 4th dimension was used by L'Engle in "A Wrinkle In Time", which eagleboy was just referencing as an example. Guess what though, the general scientific community DOES consider time to be a 4th dimension! (ever hear of spacetime? look it up.) So, maybe you shouldn't bash someone's points if you don't what you're talking about yourself. Like I said before- do a little research. Wikipedia will do. The notion of time as the average person thinks of it is NOT necessarily the same as how the scientific community sees it. |

One thing the Wiki article mentioned is that nothing, now or ever, is faster than light, because it moves through space but not time. Also according to to "quantum decoherence," parallel universes are inaccessible to us. Time traveling requires at least one of the following: 1. Traveling faster than the speed of light 2. Using "cosmic strings" and "black holes." 3. "Wormholes" and "Alcubierre 'warp' drive" (the latter resembling that of the Series "Star Trek") If you need help, Wiki the terms put in quotation marks. |

I cannot personally dismiss or prove that time travel is possible, but I do not believe it is for a few general reasons. 1. It personally is not logical if you can go back in time in a 'straight line' sense, as doing so would change the past. 2. I do not think you can go forward for the same reason; traveling through time in itself is going to change the course of history to where it is different than had you not done so. You may be able to pass through time relatively, but in doing so you would probably throw out the whole 'fate' idea, because of what I said above. If you can in fact travel into the future, and in doing so change the future itself, then fate cannot exist (unless there is no freewill, which is another issue entirely ^^;; ![]() Other than that, most people understand that you can change your perception of time by speeding up (or gaining mass) -> Special relatively. This does not qualify as 'true' time travel, though You are not physically traveling to another time in this case, but just changing your perception of the natural flow of time.Also, everyone here changes their perception of time on a constant basis. You 'Time Dilate' when you move around, when you drive in your car, etcetera. The reference frame change is just too small your eye and brain to take notice of.

But you're right: Time is kind of an illusion in a sense, but tangible enough to be accepted. |

Fair enough.
Time itself isn't really an illusion, just something we don't understand very well. We can grasp what we actually do understand about it, but most of our knowledge on the subject is pure speculation.
