STRING THEORY: THIRTY YEARS LATER AND NO VALID RESULTS

 
  • As a so-called “Theory of Everything” candidate, string theory aims to address various theoretical conundrums; the most fundamental of which is how gravity works for tiny objects like electrons and photons.
  • String theory is said to be unprovable as a matter of belief and is generally a political point. String theory can definitely be confirmed both in theory and possibly in practice depending on the details of how it is realized in our universe.
  • Current versions of string theory require 10 dimensions total, while an even more hypothetical über-string theory known as M-theory requires 11. But when we look around the universe, we only ever see the usual three spatial dimensions plus the dimension of time.
