Undergrad Can Shape Dynamics Be Tested Against Quantum Mechanics?

Click For Summary
Shape Dynamics aligns with Mach's principles, raising questions about its compatibility with Quantum Mechanics. The discussion focuses on how Shape Dynamics can be experimentally differentiated from other theories. Participants share resources, including an introductory paper and a talk by one of its founders, Gomez, to deepen understanding. The need for clear experimental tests to validate Shape Dynamics against Quantum Mechanics is emphasized. Overall, the conversation highlights the ongoing exploration of Shape Dynamics in the context of modern physics.

TL;DR
What would be some experiments that could falsify Barbour's Shape Dynamics?
Shape Dynamics implements nicely Mach's principles. But how well does it fare when it comes to Quantum Mechanics? How can it be experimentally distinguished from other theories?

Do you have a link explaining Barbour's Shape Dynamics?

"Supernovae evidence for foundational change to cosmological models" https://arxiv.org/pdf/2412.15143 The paper claims: We compare the standard homogeneous cosmological model, i.e., spatially flat ΛCDM, and the timescape cosmology which invokes backreaction of inhomogeneities. Timescape, while statistically homogeneous and isotropic, departs from average Friedmann-Lemaître-Robertson-Walker evolution, and replaces dark energy by kinetic gravitational energy and its gradients, in explaining...
