 The absorber theory has been used to explain quantum entanglement and led to the transactional interpretation of quantum mechanics, as well as the Hoyle-Narlikar theory of gravity, a Machian version of Einstein's general relativity.Fred Hoyle and Jayant Narlikar originally developed their cosmological model as a quasi steady state model of the universe, adding a "Creation field" generating matter out of empty space, an hypothesis contradicted by recent observations.When the C-field is not used, ignoring the parts regarding mass creation, the theory is no longer steady state and becomes a Machian extension of general relativity.
