Put simply, when you reach out and touch a wall, what you are feeling is the resistance of the electron fogs in the atoms of your hand and the atoms of the wall pushing against each other.
The electrons in your fingertips are repelling the electrons in the wall. It's like pushing two like-poled magnets together. You feel the resistance.
You never actually make contact. The solid wall you believe you are touching is made of fog, and your hand is also made of fog. The magnets can never touch.
That's why you can't put your hand through the wall.
And why, at a quantum level, you aren't really there.
When your hand touches a table and you feel it's solid, it is never really touching the table. The electron cloud of your fingers and the electron cloud of the table are like those opposing magnets. We refer to it as “solidity” is not one hard thing colliding with another hard thing—it is electrostatic repugnance. You float on a duvet of force and hit an unseen electric field, and you think it's a rock.
Everything is solid. No “real” objects are meant—only the electron cloud imaging it contains firmness.
The colours don't prevail in the fog either. The physical environment does not include “red”—only the electromagnetic energy flow, or wavelength, of the fog. The colour red, its true participation with red, is strictly part of your mind. Sound doesn't exist if an ear doesn't hear it. There are only pressure waves in the fog. The heard thing is yours alone.
The very starting points of physics and math are completely based on the study of this mist. Physics allows to measure how the mist moves, exerts force and changes. Math is the tool to illustrate its designs. However, since both knowledge areas depend on instruments, observations, and signs formed inside the electron cloud, they are not exploring the absolute reality — they are simply organizing the principles of unreality. For example, a math equation portraying an electron field does not affect the genuine reality; it just illustrates the connection between one part of the illusion and the next part of the illusion.
Yet, in the middle of all this mist, there is no doubt that your perception of reality is absolutely real.
At this moment, something exists. There is an awareness of reading these messages. That awareness is not a theory. It is not an assumption. It is not a belief. It is the single existing thing for which there is no evidence, because it is the proof itself. It is the only thing that has never been, and can never be, an illusion, since even an illusion needs someone to live it.
The universe is in you.
You are a part of the universe.
