String Theory

[mead1]

I have seen a bunch of documentaries on this and I can sum it up like this:

The smallest pieces of matter are atoms, these are made up of strings that are infinitesmally small and their vibration fluctuates atoms creating different matter. It also states that there are two types of strings, those with two ends, and those in a closed circle. The theory states that the closed circles can expand infinately in any of the 11 dimensions the strings exist in. Therefor, the theory states our universe exists upon a membrane formed by a string the size of many universi. The string theory also explains the formation of the universe as a small ball of matter caught between the bumping of two membranes larger than a universe, the resulting force caused it to expand into our universe. It also theorizes that this could potentially happen an infinite number of times, so this universe and every other are something like a sliced loaf of bread.

Now this hurts my head immensley, if someone understands it a little better, I would appreciate it if they could explain it to me. For the rest of you, Look this up, its interesting.

I know what you are talking about.

Let me explain: lets say you see water. It is composed like so: Water > Molecules > Atoms > Electrons, protons and neutrons > quarks > strings. When strings vibrate, they cause atoms to vibrate. The vibration of an atom determines its heat. If the atom vibrates a lot, it is hot.

My freind explained to me that the string theory also consists of parallel universes, but i'm really not sure about this.

But..then where did the strings come from? Something had to start it ALL...that's what puzzles me.

I know your description isn't accurate, mead, the only problem is I don't understand enough about it to point out where the inaccuracies are . . .

aracelibercelle: That's not true. There does not need to be a start, nor an end.

I've read about string theory a couple of times, and it's all far too confusing for me to understand. Strings aren't necessarily the things that make up the quarks, though. Basically, subatomic particles can be represented as waves on a string, and they interact like other waves. Although string theory can explain just about everything that we want it to (though how is completely beyond me), the universe needs to have fourteen dimensions for it to work, and that's just a little farfetched for me to accept it. It's all really confusing, and that's just what I remembered.

String theory is interesting.

I saw a show on it a while ago.

I saw an old guy break a rare thingy on TechTV or something once.

Aaaaaahhhh.... my..... Polish brain..... cannot..... comprehend the situation.......... aaaaaaaahhhh.....

Yeah I think the big misinterpretation is that people think there are actually 'strings' that are *existing*. The thing is that they don't 'exist' per se, but they're what CREATE existence. Eh?

I'm reading Elegant Universe right now.. well not really, I've just read the acknowledgements. Heh heh..

[Verruckter]

AHA! Looky looky what I found. I knew there was something like that on PBS

You are actually mixing two different, but plausably co-existant theories. String, and Brane.

[QreepyBORIS]

I thought string and Brane were related O_o.

Eh, I forgot most of my String theory, but I never got it too well.

I think that is the Scientific American website...really good, and in depth about stuff. Good magazine.

Basically, the strings come from someone called something who noticed that the microverse (really tiny stuff) is not only weird, but downright impossible with the current definition of quarks as a "point" (zero dimensions, no length, nor width or depth). However, a lot of pieces fell into place if you replaced the points with strings (one dimension, still no width or depth, but length).

Now, I don't quite know why there is a need for all of those dimensions, but I should guess it has something to do with the vibrations needed to represent all the different qualities of the quarks.

About that "all matter are waves on a string": A bit off the mark, but pretty close. What the problem really was about in the beginning was how to define light; is it a stream of particles, or is it a form of radiation? Both are true. And the same goes for basically all forms of matter. As the mass of the matter increases, however, the wave-qualities recede and so far, the biggest object science has been able to prove has radiation-qualities is a Bucky Ball (as far as I know, anyway), which is a ball of carbon atoms, usually 60-70 of them.

That's how I've understood it anyways, if anyone's got objections, speak 'em. I'm no expert on these things.
