    I'll be the first to admit that my ideas on string theory are shakey.
    So ... matter is made from strings and these strings vibrate? And cause the matter we see?

    But the different ideas of physics dont mesh together so they're looking for a grand theory to tie them all together?


    What would happen if we could make the strings stop vibrating?

    Thanks

    I think you pretty much have the basic idea.
    Particles are made up of vibrating strings vibrating at different speeds according to the mass of the matter, to make up what we feel and touch. And the theory has the potential of unifying quantum mechanics and relativity. It goes way deeper and gets more complicated, but super interesting.
    And Quantum uncertainty states a string cannot be completely still. If it were possible then we could know it's exact position and speed.
    Anyway you should get the book "The Elegant Universe" By Brian Greene. Maybe you've heard of him? He's an expert on the topic and when it comes to explaining the theory and everything behind it he's a good writer too. If you don't get your answers here or elsewhere on the web, you'll probably find them in the book.

    Ignore string theory. It is only a desperate attempt to progress farther in physics. Allot of what they "theorize" originates from some type of self need within them to make physics elegant. "Ohhh, yes, vibrating strings like the strings on a violin!!! How wonderful!" I have heard many physicists talk about string theory...it is like listening to some 70's hippie attempting to explain how a tree is.
    Of all the wonders in the universe, none is likely more fascinating and complicated than human nature.

    "Two things are infinite: the universe and human stupidity; and I'm not sure about the universe."

    "Great spirits have always found violent opposition from mediocrities. The latter cannot understand it when a man does not thoughtlessly submit to hereditary prejudices but honestly and courageously uses his intelligence"

    So what's your theory? I agree with some of what your saying, i think there's a reason its called theoricial physics :-D

    Strings?! Like on a balilaika? To vibrate, the strings need to be pulled by both ends. TWANG!

    Think RODS. A rod, unsupported at all, can vibrate even as it falls thru the air.

    Think marbles. "Everyone knows" that atoms are like marbles, only smaller. Each marble can vibrate, but it takes special instruments to hear a marble vibrate.

    Resurrecting a 5 year old thread, especially with stupidity like this, is particularly idiotic.

    While this thread is likely to be closed soon (seriously, what's up with the necromancy), I just want to point out that...

    This is wrong. (Strings are just very flexible rods.)

    This is also wrong. (It's an old, no longer accepted model of atoms.)

    This is also wrong. (If you drop a marble on the floor, some of the sound you hear is from the marble vibrating. I bet you could suspend it with a drop of glue and a string and get it to make a more prolonged noise.)

    MODERATOR WARNING : What bit of my last warning did you not understand ? So for the final time - do not resurrect old threads from years ago. Necro-threading is not acceptable here. Your next attempt at resurrecting a dead discussion will earn you a time-out. Closed.
