This question already has an answer here:

I happened to get my hands on a string theory book where its been said that the universe's fundamental particle i.e. the string, takes about ten dimensions for specifying itself under symmetry. What are those?

    $\begingroup$ I'm confused by the multiple downvotes on this. It seems like a legitimate question for this site. Would the voters care to clarify their positions? $\endgroup$ – wsc Jun 15 '13 at 16:23

  • $\begingroup$ @wsc: I downvoted because the question is too "popular science"-ish and doesn't really make it clear what it is asking "specifying itself under symmetry"?! Sounds like something taken from an innnaccurate popular science book like "String theory for dummies" $\endgroup$ – Abhimanyu Pallavi Sudhir Jun 18 '13 at 4:07

It depends on what theory are you useing, in theory of relativity there are only four dimensions $x^{\mu}$ but in another theory like general relativity there is a higher dimension which there is a constraint to eliminate the artifical 5th dimension (schwartzchild metric).

  • $\begingroup$ Wrong. Schwarzschild is a solution to GR. KK theory is what you're talking about. And GR can be generalised. $\endgroup$ – Abhimanyu Pallavi Sudhir Sep 14 '13 at 13:02
