Standard Model Is One of Infinitely Many Theories
The standard model of particle physics is itself just one of an infinite collection of theories differing by the values of constants like the electron mass and force strengths, which we determine not from first principles but by tuning the theory to observation — so having many possible universes from string theory is not unfamiliar.
