Mordehai Milgrom on Modified Newtonian dynamics

“... the interpretation of MOND as modified inertia (MI) ... ... Who is afraid of modified inertia? The interpretation of MOND as MI was on the table from the very inception of MOND ...”

“We do not know to what extent and how MOND affects nongravitational phenomena such as electromagnetism (EM). For example, if there is a consistent way to extend and apply the basic tenets to nongravitational physics.”

“Another crucial point is that MOND as we know it now is arguably only an approximate 'effective field theory' that approximates some more fundamental scheme at a deeper stratum — some 'FUNDAMOND' — conceptually, in a similar way to thermodynamics being an approximation of the statistical-mechanics, microscopic description.”
