The Earth is not large enough to build a particle collider big enough to test if String Theory describes the most elemental particles or if there is something smaller. We might be only a handful of generations of particle accelerators until spaced based colliders. All of this is to say, you’re going to need to be okay with you personally never knowing this answer. It’s all theoretical.
