I was just wondering... I somehow landed on some strange new (or old i dont know) theory that everything is made of strings. Like things that are wierd circular membranes. Does ANY one know ANYthing about this?

I saw a special on PBS once called 'The Elegant Universe' that explained it quite nicely.

http://en.wikipedia.org/wiki/String_Theory <--- Also a nice article.

im lost though... it is sooo hurting my BRAIN!!! I cant feel my head... This is what i got

There are 11 dimensions.
Every 8 there is an exact clone of you.
There can be a dimension in front of me.
..... IDK anything else!!

String theory was thought up in the seventies, when a scientist saw that an equation for some small particle (forgot which one) was shaped like a spring. The particle would vibrate, and this had developed into a theory that these small vibrating strings made up everything. I did not see this pbs show, but I read "The Elegant Universe" by Brian Greene. It's confusing, but it has really good analogies for properties of these particles.

doesnt the theory go that everything is made up of these strings and that heire are some manu universe in front of us but we cant see them because they are so small that they are invisible?

i also saw that pbs show, its quite interesting but i prefer not to think of the world around me like that. Not saying its wrong.

Man I wanted to see that PBS show, I had the schedule but gay PBS decided to not show it and showed some other crap show -.-

I read the link that exo posted, i belie the general gist is that string theory is a way to explain some universal forces such as gravity and elctromagnet field through the coiling of these strings, but the only way to explain these strings is that there has to be a certain number of dementions, namely either 11 or 26 dimensions. the way they explain thse extra dimensions above 4 is that they are all so small and compact that the naked eye could not see them, and they wouwlnt effect onjects passing through them and such, but they do give off some forces.

String Theory explains the begining of our Universe.

To understand String Theory you need to know these thigns first.

There are 11 dimensions.
3 would be X,Y,Z composing the 3D world in which we live in.
1 would be Time
7 would be other types of dimensions which we can't comprehend because there are different laws of physics applying in those dimensions.

The theory of SuperGravity says that gravity is the weakest force in our Universe.
Heisengurg stated that it is imposible to determine the speed and location of an object.
Theory of Gravity(Newton's theory is flase) - It does not state that gravity is like when Newton stated when a greater mass pulled on another. It states that gravity is like a 3 dimensional grid where it is stronger on some places than others.

String Theory - The "space" in which our Universe does not occupy is filled with either membranes or other universes. These membranes have many different shapes that can be written with an equation like circles, ellipses, donuts and similar shapes. The outer edges of these membranes are irregular. When these membranes collide they will form a Universe. When each part of a membrane collides, it will create matter derived from the combination of "Energy" from different combinations of dimensions. Membranes could be in our Univerese thus "stealing" space from us. These membranes could collide and create a Universe inside ours. The Universe would separate from ours in a matter of seconds because it has grown too large and the other universe would simply dissapear from our perspective.

My null theory(not proven true or false) - It is based on the end of our Universe. Since the Universe keeps expanding and expanding, gravity will get weaker in some spaces and when it gts so weak that it nullifies and thus no gravity will exist in that space, thus the Universe won't exist there. It will eventually keep expanding until it is no more.

As of 2005, string theory is unverifiable. It is by no means the only theory currently being developed which suffers from this difficulty; any new development can pass through a stage of unverifiability before it becomes conclusively accepted or rejected

Screw that string theory. Screw all theories. Only thing you need to believe in... Actually, know, is donwanism. Convert or die![/center]

All quantum theories cannot be varified to be true, because any attempt at seeing what they truly are is using equipment bigger than the object itself. The only way to tell if a quantum theory would be correct is if all other theories (present and future) were disproven. We will probably never truly know what happens at the string level, but we will probably be able to use the theory to predict consequences of certain events.

So would the time dimension effect the other seven dimensions? If it does, than would the x,y, and z dimensions effect it as well?

Unless the seven dimensions were some how detached. What if this dimension was created by one of the other seven, and if they keep mutating and breaking away how are there only seven? Is it some strange darwinism spin that creates a new dimension as soon as another disappears??

Firstly, the idea of 11 dimesions was around before string theory, as it was thought up in the 1920's.
To truely understand quantum physics, you have to know forces. Gravity and electromagnetism are feild forces, which means that they can be seen at a scale above the atomic. The other forces, strong (bonds neutrons to protons) and weak(radiation) cannot be felt over distances. You can think of gravity and electromagnitism as also using the x/y/z + time dimentions. The other forces don't really have any effect on these dimesions. The extra dimensions, it is theorized, explain the properties of the other two forces, and possibly other properites of the first two as well. A (bad) example of this would be if the charge of an electron increased, it was moving in one of those new found dimesions. This is the same as if we measured the placement of an object moving through time. Thats as best an explanation as I can give... Go find your own.

Come to think of it, why aren't our perceptions different dimmensions as well? Sight...smell...etc.

This will be very difficult to explain because it is imposible for any human to understand the other 7 dimensions because we cannot see them or portray them.

There might be more than 7 but we may not know about them. We only know about those 7 because we have created equations that state that for most laws of physics to work, the loophole(other 7 dimensions) have to exist in order for the laws and theories to work and thus, those dimensions were proven to exist by means of an equation.



Actually, by the time of Einstein's death in the 1950's there were only to be 10 dimensions known to physicists. Einstein was the first to start working on the one theory that could explain everything, his uncompleted work led other phycisists to create String Theory.

In the 1980's where most physicists believe that String Theory was the theory that Einstein pursued went wrong. Because there were only 10 known dimensions, there were 5 different forms of String Theory all with loopholes in them. It seemed like String Theory would collapse until a British physicists discovered Super Gravity Theory which explains the existance of the missing 11[sup]th[/sup] dimension. Once this was applied to String Theory it all made sense and the 5 different String Theories all become one.

Sight cannot be a dimension because it is an electrical perception of 3 dimensions. Colors radiate different types of wave radiations which stimulates the different parts of the eye and the eye sends electrical impulses to the brain and this is how we see.

Touch would be electrical impulses of when some outside object triggers a nerve. The nerve then sends electrical impulses to the brain telling it that an outside body is in contact with the human body.

Smell and Taste would be derived forms of touch.

Sound would be the conversion of Sound Waves into electrical impulses which the brain then percieves into hearing.

Basicly, the 5 senses would be all electrical and not dimensional.

Einstien hated quantum mechanics though, I remember hearing "God doesn't play dice" and what not. I thought that he simply wanted to find a different way of explaining quantum physics that went with his ideas of relativity, unlike today's form of a TOE combining the two parts of physics.
Didn't know that there was only ten dimensions back then though.

When you see things it doesn't stimulate different parts of the eye, it is recieved through rods (depth) and cones (color & brightness) the areas on the eye tell the brain where on the visual feild it is located.

Touch and sound relate to pressure points of some kind.

Smell and taste are from a reaction of chemicals to certain binding sites on the membranes of cells. Smell is odd though because it transfers data directly to the center of the brain, while the other senses go through other systems of the brain before being registered.

-My brain really hurts alot!

-that would be cool if there were things happening right in front of us that we dont even know about

-its a little weird but i hope its true...


But if it is- we have to take this emoticon out. Make him stringy

So then if one did grow and a universe would form how would that affect us? Because these membranes crash very so often. then if one of them crashed into ours then there would be a created universe in ours, takin our space then wouldnt we be dead because if the "universe" started right between us and the sun, we would be dead, cuz we would not have a sun of our own anymore, thus everything turning into ice and we be icicles walking around.

einstein didnt start the theory of everything... he just progressed it, the theory of everyhitng has been the long term goal sense the birth of physics.

That won't happen. A Universe can be created inside ours but once it grows(after several seconds of it's Big Bang, when the Singularity Charge is gone(1x10[sup]-34[/sup]seconds) it will be gone). It is either the time I stated or when the first atoms start forming. The other Universe inside ours will just "dissapear" into its own realm.

Very interesting reading! From an ex-math teacher, "Good to see that youth is still interested in science outside of school!" A friend of mine, Paul Bryson, was involved in a recent movie titled "What the bleep do we know". Recently I went to our local Nickelodean and saw this small film. While it tended to be a bit superficial and only touched the surface of quantum physics, it was entertaining. Maybe a movie to rent if you're stuck at the video store and can't find something you like. Interesting how the unconscious, subliminal, and micro universe correlate. The hippies here in Santa Cruz, Ca seemed to get a big kick out of it.

Ok ... enjoy your topic... don't mind my interruption

I saw that movie. It was good, but it was (for me) mainly review. I would recomend it for anyone who wants to know about the basics of quantum mechanic, hormones, and overall science.
