We argue that MOND’s acceleration scale constant favours Mach’s principle instead of the quantum vacuum as the underlaying phenomenology explaining MOND. This is due to the fact that, while the cosmological constant remains mysterious and it is measured indirectly, the mass and size of the universe are measured directly. Moreover, Planck’s constant does not appear anywhere in MOND.

We explain our failed attempt to extend MOND in order to explain galaxy cluster dynamics without dark matter, following the ideas of Jacob Bekenstein and HongSheng Zhao. Is the Machian gravitational potential of the universe the scale needed to solve the mass discrepancies found in galaxy clusters?

We briefly comment on one of the papers behind the Brans-Dicke theory and its similarities with Modified Newtonian Dynamics MOND in relation to Mach’s principle. Does a metric theory need to violate Birkhoff’s theorem to satisfy Mach’s principle?

Research in Mach’s principle lost interest by the physics community after the results of Brans-Dicke theory. Another objection often raised against Mach’s principle is the claim that it implies some sort of anisotropy of inertia. We explore this idea based on Dicke’s and Treder’s claims. Does Mach’s principle necessarily imply the anisotropy of inertia?
