[QUOTE="Drakkith, post: 5470295, member: 272035"] Indeed but it is [B][I][U]nothing[/U][/I][/B] like what you're imagining and there is no evidence supporting string theory over any other physical theory. I'm not sure where you're getting this from. There are exactly zero mainstream, accepted theories used to model things in real life that have more than 3 spatial dimensions. There are certainly other theories out there with more than 3 spatial dimensions, but they are not accepted as of yet (mainly because we have yet to find a situation where they describe space better than GR).
