Einsteinians Want Granular Spacetime

Sabine Hossenfelder: "...hints at a deeper truth: that space-time is made of small elements whose collective motion gives rise to the force we call gravity. In this case, gravity would not be a truly fundamental phenomenon, but an emergent one." https://www.forbes.com/sites/startsw...rgent-gravity/

My comment in Forbes:

This "deeper truth" is not even wrong. Spacetime is not an ab initio model that one can modify (by introducing granularity for instance). It is a CONSEQUENCE of Einstein's constant-speed-of-light postulate, and if the consequence is unsatisfactory, the postulate must be false (logic forbids the combination "true postulate, wrong consequence"):

"Special relativity is based on the observation that the speed of light is always the same, independently of who measures it, or how fast the source of the light is moving with respect to the observer. Einstein demonstrated that as an immediate consequence, space and time can no longer be independent, but should rather be considered a new joint entity called "spacetime."
