Paper by Brian Whitworth who has a theory that certain aspects of relativity theory could point to our living in a virtual environment.
I found this paper interesting in that I had recently thought about the relative nature and (for instance) slowing of time for objects moving at a high rate of speed and whether these aspects of reality could be related to finite processing capability at specific points in space.
The argument for the existence of all possible worlds has in the past been deemed problematical due to the failure of induction it implies. In this paper I argue that by focussing on an approach that distinguishes a hidden reality from the world of appearance, and on a corresponding generalisation from 'all possible worlds' to 'all possible states', this problem is readily surmountable. Moreover the positive success of inductive reasoning and the lack of observed paranormal events emerge as a natural consequence.
