1. In quantum mechanics events are attached to probabilities. However in General Relativity time is "distortable." Thus probabilities change and may be increased.
In Penrose Objective Reduction theory, gravity is already identified as the driver of reductions (collapses) based on (mass and) distances. The above observation suggests another way for gravitation to influence reduction.
2. Separately, if instead of gravitation we speculate that a physical fundamental consciousness field is the driver, we have a situation where fundamental consciousness drives collapse. O.R. speculates that consciousness is consequential to reduction. Per the discussion here, it may be the reverse, or bidirectional- either serially in time or as a simultaneous transaction. This would represent a two-way link between "the worlds of extended and nonextended objects" and more specifically one way for neurons ultimately to link to fundamental consciousness and back.
We note that this generally reinvigorates the Conscious Causes Collapse view of QM. At the time of invention and succeeding years, when said consciousness was generally viewed as a miniature of that with which we are personally familiar, this interpretation fell out of favor as unlikely.
However modern lines of thought on consciousness include the view that minds are composed of feeling plus information processing, with the latter a macroscale construction and the former necessarily fundamental. At this scale, as fundamental quanta of feeling necessary to bring a "Theory of Everything," which excludes consciousness, to a Theory of All, which includes the undeniably extant phenomenon of consciousness, it becomes much more natural and plausible to consider that possibly Consciousness causes Collapse. In this case the consciousness is not, proximally, an observant mind, be it of any size, but a particle interaction. But these interactions may be caused by system-level machinations of a mind.
In a theoretical case of certain massive minds with high introspective capabilities it is even possible in principal for them to make some "external" things happen. Which says only that much and nothing more.
