A Knowable Gaian Mind
There will be an amazing new discovery in physics on a par with the discovery of radio waves or the discovery of nuclear reactions. This new discovery will involve a fuller understanding of the level of reality that lies "below" the haze of quantum mechanics—suppose we call this new level the domain of the subdimensions.
Endless free energy will flow from the subdimensions. And, by using subdimensional shortcuts akin to what is now called quantum entanglement, we'll become able to send information over great distances with no energy cost. In effect the whole world can become linked like a wireless network, simply by tapping into the subdimensional channel.
This universal telepathy will not be limited to humans; it will extend to animals, plants, and even ordinary objects. Via the subdimensions you'll be able to see every object in the world. Conversely, every object in the world will be in some limited sense conscious, in that it will be aware of all the other objects in the world.
A useful corollary is that any piece of brute matter will be a computer just as it is. That is, once we can reach into the inner self of an object, we'll become able to program the behavior of things like rocks or log—without our having to attach any kind of microprocessor as an intermediary.
Humans will communicate at a vastly enhanced level. Presently I communicate an idea by broadcasting a string of words that serves as a program for reconstructing one of my thoughts. Once we enjoy subdimensional telepathy, I can simply send you a link to the location of some particular idea in my head.
Machines will fade away and, in particular, digital computers will be no more. The emerging interactions of Earth's telepathically communicating beings will become a real and knowable Gaian mind. And then we will become aware of the other higher minds in our cosmos.
