I'm sorry, but I disagree with the label "fundamental" here. One can observe anti-de Sitter spaces in superfluid systems. Is that not more "fundamental" than zoology of particles and their interactions? That has, literally to do with the metric tensor of space. Seems to be a bit more fundamental to me than things interacting in that space. Put another way, the "fundamental" argument is very weak, and everyone outside of HEP knows this.
