Hello, I hope this is not a stupid question as I am not a physicist. But I was curious about how contenders for the so-called Theory of Everything view the shape of the elementary particles. I know that the basic idea of string theory is related to the shape of elementary particles as one dimensional, as opposed to zero-dimensions of classical mechanics, to include Quantum Theory. I am curious what is the shape of elementary particles in other theories that seek to unify QT and GR, such as Quantum Field Theory? Thanks.
