editEtymology
editNamed after German physicist Ernst Mach, to whom the hypothesis is often attributed. Coined by Albert Einstein, who sought to incorporate the hypothesis into his theory of general relativity.
Proper noun
edit- (physics) The principle that the inertia of a body arises from its relation to the totality of all other bodies in the universe.

- We now discuss a theory of gravitation and cosmology which is perhaps more strongly rooted in Mach's principle than any other theory discussed so far.
- 1995, Wolfram Schommers, Symbols, Pictures and Quantum Reality, World Scientific, page 94:
- Thus, in any case, quantum theory is based on an absolute space-time picture and, therefore, in these formulations Mach's principle is not fulfiled.[sic] The following important question arises: Can quantum phenomena be treated in accordance with Mach's principle?

- This is most famously embodied in Mach's Principle (so named by Einstein), which in its simplest form states that 'mass there influences inertia here'. More formally, it says that inertia is causally determined by the large-scale distribution of matter in the universe.
- Synonym: Mach's conjecture
