No*. The map is not the terrain.

Now stop spamming the forum and read a bit of it before asking a basic question.

ETA *should have said maybe.


1 - SU(1)
2 - The SU(3), SU(2) and U(1) symmetries of the standard model.
3 - Different kind of symmetry, the so‚Äźcalled flavor symmetry,
which turns out to be only approximate. Flavor symmetry is not
associated with the forces of the standard model; instead it
pertains to the particles, especially the quarks, between which
the forces act.
4 - "SU(5)" For the specific grand unification theory,
5 - supersymmetry (without experimental evidence)
6 - . . .
---
To create a new symmetry is needed a new force.
Many symmetries - many forces.
One more symmetry and horse will fly.
