String theory analogy
Web$\begingroup$ The ant on a string analogy has always bothered me. We're watching the ant while we're embedded in 3D. The ant isn't moving in any extra dimension from our POV. Its motion is constrained, but still embedded in 3D. Its motion isn't higher-dimensional, so how does the analogy explain anything about extra dimensions. Basically, I don ... http://philsci-archive.pitt.edu/16353/1/Philosophy%20of%20String%20Theory.pdf

WebAnswer (1 of 3): String theory, which gradually evolved into M-theory(combining the 5 string theories) has actually made a lot of predictions.

WebNov 24, 2015 · In principle perturbative string theory is well defined: This says to pick a 2d super-conformal field theory of central charge 15, collect its n-point functions into one formal power series, interpret this as a loop-wise finite, hence normalized, scattering matrix known from QFT, then study this.
