    Some scientist says that we live in 10-dimentional universe. This theory is confirmed by mathematical calculation results. First 3 dimensions together with time as a fourth dimension create a world, which is experienced by us. The next 6 dimensions are bent to so small size that they are unable to identify by our research instruments. The name of this theory comes from simplified model of such universe, which take into consideration 3 well recognized (long distance) dimensions and additional one - bent one. Such bent dimension creates in our world some kind of tiny pipe – just a string.
    Now, I need your help.

    The name of this theory suggests that such model is limited to cases where only strings exist. I’m wondering if why, such bent dimentions can exist only separately?
    I’m asking, because if we imagine the model where we take into consideration 3 well recognized (long distance) dimensions and two additional (bent) but bent together we get a torus, not a string. In next step ( three dimensions bent together) we get a ball. What results will be on further steps – God knows. It is easier for me to imagine that elementary particles in our universe are created by such balls or toruses, not by strings. Tell me where I’m wrong.

    Ivan,

    Steven Hawkins (I believe that is his name)covered superstring theory in one his books which I read many years ago. I had a hard time with it because I, too, could not create a mental image of a superstring.

    I wish I could help. Let me know what you discover. <img src = "http://users.esc.net.au/~nitro/BBoard_member_gifs/bowser_anim.gif">

    Ivan,

    I now find myself searching for the above mentioned book, but I'm not having any luck. Do you have a URL to share? I've a spark to give this subject another look.

    I think the superstring theory lets Quantom Mechanics and General relativity coexist together, and If I remember correctly it says that they must exist together.

    I don't believe a string literal, but a string that binds the two other theories together.

    Here's a website with some good links on the subject. I might be gone for a bit--a person could get lost in this stuff.

    Also, It's Stephen Hawking whoes book I was referring. Sorry, Folks.

    Ivan,

    <img src = "http://users.esc.net.au/~nitro/BBoard_member_gifs/bowser_anim.gif">Yes, it does have some very good graphics, but you should look at the links on that site, too. I spent my afternoon surfinging them. I'll be there again tonight.

    Thoughts,

    <img src = "http://users.esc.net.au/~nitro/BBoard_member_gifs/bowser_anim.gif">After reading some of the pages online, I'm pretty certain they're using a string literal as a visual aid to the theory. It's very hard to grasp because were talking dimension which exist beyond our physical comprehension.

    It's all very lofty stuff and way over my head, but I love it. Before I die, I hope they find a test which will prove or disprove the theory.
