| Nov 15, 2016 at 23:29 | comment | added | Prahar | There are different explanations for the numbers 10, 11, 26 all of which come from some theoretical requirement of internal self-consistency of the mathematical theory. You will need some background in physics and mathematics to truly understand. What is your current background? | |

| Nov 15, 2016 at 22:19 | comment | added | Howard Miller | I don't really know anything about string theory, even though I have wondered the same thing. So since I'm no authority I'm making a comment rather than an answer. A string is an infinitesimally small thing that is characterized by its vibrations. To account for all of the physical characteristics of the universe, strings would have to vibrate in multiple dimensions. So there are theories that try to make a TOE with vibrations in 10 dimensions, another in 11 dimensions and another in 26 dimensions. Maybe in actuality there are an infinite number of dimensions, most of which are not used. | |
