This BBC documentary is another “multiverse” explanation. They start out with physics concepts putting emphasis on the cosmological constant and then move more into metaphysics (which you really have to do at some point). The cosmological constant is specific out to 120 decimal places. Einstein used this to describe energy density of the vacuum of space. I won’t pretend to really understand what that means except it is key to a number of physics equations. Anyway, even changing the 120th place of the number alters life as we know it. If there are constants like this (pi, gravity, speed of light) then that seems to imply that something is setting that value. The theory of the multiverse is used to side-step the notion of a creator by saying that all possibilities exist at the same time. So there are universes that represent all possible values. But then there has to be something that sort of lays it all out.
The issue I have is that if there is a simulator that can tune the variables and change the algorithms, then wouldn’t it at some point want to interact with the simulation once the simulation got to a certain point? Or if there are simply multiple universes that represent all permutations of constants and algorithms, then wouldn’t there be a few that could break through the shell and contact the other universes? The answer can always be “No, we are not one of the breakthrough universes” or “We are not mature enough yet”, but I have to say why. We are manipulating the world around us at an unbelievable rate. If we can dream it up, we can make it happen in the physical world. All that growth seems to do nothing for how we treat our fellow human beings, so technological growth without compassion is useless. If there is some sort of singularity event, we will all literally be connected and one. How can something that is one fight with itself? Insanity.
Forgetting all of the metaphysical multiverse, multiworld stuff, it is hard to deny that things happen from an individual’s own perspective. This perspective is filtered through our senses which actually interact with the world. The senses are interpreted by the brain and some sort of thought is formed. That experience is unique, individual. Yet there is an undercurrent of reality that the senses directly interact with or we are really interacting with everyone else’s experience. Experience experiencing experience.
