Timetravel

[Dreamer]

So many long posts! I love this topic, and I want people to read this, so it will be a short as possible

First off, Timeline is a great book. Read that one. Michael Crichton is a fine author. Not great, but good enough

Okay, time travle will probably only be possibly through simulation, ie, into other dimensions similar to our own. Othe existence of other dimensions has been proven! w00t! Scientists took a beam that could shoot only several protons at a time at a piece of photo sensitive paper. There were several dots on the page, uderstandably. The photons were hitting eachother and bounsing around. Then they tried firing one photon on the page. Theory would be that it would be only one dot. But wait! Oh no! There were several, all over the place! But why? Only one photon at a time! Well here's why: photons from other dimensions were displacing the photon. Interesting, no?

It's called the souble slit experiment. http://www.johndobson.org/articles/by/doubleslit.html

Timeline is an awesome book!
Michael Crichton is my favorite author.

There is no such thing as time travel because time is not a place.

I agree MasterChief, he puts a lot of effort of making sure that the stuff in the book is based on fact. On his last book for example, he spent a year researching, before writing the book.

Not that this should be a Michael Crichton thread or anything, but Airframe. Another fabulous book. Now that was good.

I just thought there was too much commercialization in some of his other books. Didn't care for Jurassic park too much, too much conjecture. And Lost World? Don't get me started. I'll never get those 6 days back. But sphere was very good. Musta finished tha tpuppy in 2 1/2 days. Of course it was finals week when I read it, and I will do anything but study during finals week...

In the first place, this question is purely academic (you're thinking, duh), because time travel is impossible. And I don't mean, "We don't have the technology," impossible, but really impossible, because there is no such thing as time; it is merely a perception, a way of describing the world. It's kind of like color, because, although color is everywhere, nothing actually has color, it's just that our eyes perceive light bouncing off them at different wavelengths. I think that this is a pretty good analogy. In the second place even if you could "go back in time" you couldn't change anything, because the changes would already have happened. That's what I think.

Sources:
Good for ideas of time travel and multiple universes:
"Timeline" by Michael Crichton
"The Dilbert Future" by Scott Adams (no, really)

Very, very BAD for ideas of time travel and multiple universes:
All the "Terminator" movies
the movie "The One"

I disagree with you, Aether, Time is made up of two dimensions, linear and lateral time, For more Info . I provide the link because there is a lot of info and if you really care anyone really cares they will take the time to read it. If there was no time, everything would remain in a sort of static phase. Just because you can not perceive it through experience does not mean its there. How would a two-dimensional being percieve a 3-d world.? Not through experience, but through mathematical (geometrical) calculations.
