noz92 Posted July 27, 2004 Share Posted July 27, 2004 how can 1-D super strings vibrate in 10-11 dimensional universes, and effect all of them at the same time, if something is 1-D, does that make it possible to vibrate in multi-dimensions at the same time?

ydoaPs Posted July 27, 2004 Share Posted July 27, 2004 a 3D planet can effect the four extended dimensions, why wouldn't a 1d string effect 11 dimensions? Link to comment Share on other sites More sharing options...
noz92 Posted July 27, 2004 Author Share Posted July 27, 2004 but don't super strings (if i understand them correctly) actually make up subatomic particles such as quarks and protons. that's kinda' weird, imagine 4-D things making up 6-D things.

ydoaPs Posted July 27, 2004 Share Posted July 27, 2004 not protons. quarks, electrons, neutrinos, photons, gravitons, ect are strings. baryons and fermyons aren't. Link to comment Share on other sites More sharing options...
noz92 Posted July 27, 2004 Author Share Posted July 27, 2004 then what are baryons and fermyons made of? Link to comment Share on other sites More sharing options...
noz92 Posted July 27, 2004 Author Share Posted July 27, 2004 not protons. quarks, electrons, neutrinos, photons, gravitons, ect are strings. baryons and fermyons aren't. and if protons aren't and quarks are, how is that possible if quarks make up protons?

ydoaPs Posted July 27, 2004 Share Posted July 27, 2004 no, protons are made of quarks. quarks are strings. Link to comment Share on other sites More sharing options...
Guest ViperX883 Posted July 28, 2004 Share Posted July 28, 2004 As far as I know there are mesons, which are composed of a quark-antiquark pair, baryons, which are composed of three quarks, exotic baryons, which are composed of five quarks, leptons, which are individual strings, and bosons, which are also individual strings. In the end everything woudl theoretically be made of strings. Also, the more modern version of String Theory involves not only one-dimensional strings, but also multi-dimensional "branes". This may be the answer to the question regarding how strings are able to affect multiple dimensions. Also, it is believed that 7 of the 11 proposed dimensions are wrapped up so tightly that even strings cannot exert any affect on them. They are on the order of the Planck length, and may even represent the Planck length. Link to comment Share on other sites More sharing options...
ydoaPs Posted July 28, 2004 Share Posted July 28, 2004 what are exotic baryons? last i read, strings were larger than the plank length. Link to comment Share on other sites More sharing options...
Solaris Posted July 28, 2004 Share Posted July 28, 2004 I found something interesting: Did before the Big Bang existed a String Bang??? Link to comment Share on other sites More sharing options...
Solaris Posted July 28, 2004 Share Posted July 28, 2004 A brief table of string theories: Bosonic 26 Only bosons, no fermions means only forces, no matter, with both open and closed strings. Major flaw: a particle with imaginary mass, called the tachyon I 10 Supersymmetry between forces and matter, with both open and closed strings, no tachyon, group symmetry is SO(32) IIA 10 Supersymmetry between forces and matter, with closed strings only, no tachyon, massless fermions spin both ways (nonchiral) IIB 10 Supersymmetry between forces and matter, with closed strings only, no tachyon, massless fermions only spin one way (chiral) HO 10 Supersymmetry between forces and matter, with closed strings only, no tachyon, heterotic, meaning right moving and left moving strings differ, group symmetry is SO(32) HE 10 Supersymmetry between forces and matter, with closed strings only, no tachyon, heterotic, meaning right moving and left moving strings differ, group symmetry is E8 x E8 Link to comment Share on other sites More sharing options...

ydoaPs Posted July 28, 2004 Share Posted July 28, 2004 what is it supposed to be? brane theory (an offshoot of string theory) has a cyclic universe. in which there was no one big bang Link to comment Share on other sites More sharing options...
noz92 Posted July 28, 2004 Author Share Posted July 28, 2004 thats kind of what i've always thought, but had nothing theorizing, or stating that. Link to comment Share on other sites More sharing options...
alt_f13 Posted July 29, 2004 Share Posted July 29, 2004 I like brane theories. Gives me hope for the future. If that sounds ironic, it is. What is this string bang all about? Link to comment Share on other sites More sharing options...

Scott Posted February 16, 2005 Share Posted February 16, 2005 The will of the universe causes the strings to vibrate... or not. Eh, who knows, i cant really think of how they could vibrate except from some divine source. Link to comment Share on other sites More sharing options...

Eh, who knows, i cant really think of how they could vibrate except from some divine source. Of course I have an incomplete (read wrong) view of the Universe but I don't picture a vibration so much as cycles in extra dimensions. So this "space" combined with the energy/momentum in this closed "space" effects the "vibration". Link to comment Share on other sites More sharing options...
