One of the more interesting concepts being discussed lately and making it’s way closer to main stream is Retro Causality. For the purposes here, it means the future can effect the past.
Some interpretations of Einsteins theory of relativity lead to the idea of the “Block Universe”. A universe where the past, the present and the future exist simultaneously. We simply live in the illusion that there is a direction to time…forward. See the diagrams below.
Rather than flowing forward, different points in time are represented as different dimensions within the block. Like one amorphous loaf of bread, something that happens to one crumb within (say the growth of mold) effects the crumbs next to it, no matter the direction.
Some say the Global Consciousness Project at Princeton University may have evidence to support this theory. Apparently, information about the tragic 911 attacks was accessed by our collective unconscious before it occurred.
