  I propose a novel interpretation of quantum theory, which I will call
Environmental Determinacy-based (EnDQT). In contrast to the well-known
interpretations of quantum theory, EnDQT has the benefit of not adding
non-local, superdeterministic, or retrocausal hidden variables. Also, it is not
in tension with relativistic causality by providing a local causal explanation
of quantum correlations. Furthermore, measurement outcomes don't vary according
to, for example, systems or worlds. It is a conservative QT in the sense that,
unlike theories such as spontaneous collapse theories, no modifications of the
fundamental equations of quantum theory are required to establish when
determinate values arise. Moreover, in principle, arbitrary systems can be in a
coherent superposition for an arbitrary amount of time. According to EnDQT, at
a certain stage of the evolution of the universe, some systems acquire the
capacity to have and give rise to other systems having determinate values
through an indeterministic process. Furthermore, this capacity propagates via
local interactions between systems. When systems are isolated from others that
have this capacity, they can, in principle, evolve unitarily indefinitely.
EnDQT may provide payoffs to other areas of physics and their foundations, such
as cosmology, via the features of the systems that start the chains of
interactions.
