| "Sounds more like metaphysics?" The regular arrow of time from the human perspective, "leaks" changes into the future. The future is constantly being changed by the past. You can measure those changes by many ways, the 2nd. law of thermodynamics is everywhere just to make sure you see this happening across everything. So, probably there are other non-discovered underlying mechanisms in the reality that are already signaling changes from the future "leaking" into the past, changing the past right infront of us, without us noticing it. A probably omnipresent mechanism for observing the future changing the past, valid in the whole cone of light visible to us, is the probability law. If you have 10 millions of possible events in a probability, one of them is the exact thing it will happen in the future, hence the information of what happens in the future is right here, existing in the past. Yeah, you can say how would the nature could use this information without powerful processors predicting branches trillions of times per second on Earth right now? Well, the brain is a pattern predictor, quite several parts of the brain are firmly attached to the physics of the universe, biochemically but what if the pattern prediction mechanisms in the brain are actually an adaptation of the evolution, just like wings to fly, but with those mechanisms the brain uses probability to "see" information from the future, and here in the "present", it changes the past (from the perspective of the future created originally from the past), if the brain "chooses now" to do something different that what originally created the future it "saw" by analizing patterns, essentially evaluating probabilities. So the Probability Law would be a kind of Inverted 2nd. Law of Thermodynamics. It would work perfectly as law of the universe: from the future to the past, the revered time of arrow, one single event created "a" future, but from the regular arrow of time, there would a range of probable future outcomes which you cannot precisely say it has "1" (100%) probability of ocurring, right to exact moment till the future becomes the present. And it was right there all the time, something obvious infront of everybody in the world, like electricity (which was suspected by many across thousands of years, but just "discovered" recently). https://en.wikipedia.org/wiki/Law_of_total_probability |
