I want to share how we can think about energy, in particular light, in different dimensions via a couple of short briefs, this one being the first one to get our feet wet.
First let's start in 2D. Think of a two dimensional plane. In 3D we have a pin (a line) that will rip a hole in the 2D plane at spot X,Y and create a void in this plane where there once was a flat "link". The infinitesimally small point where the break in the plane happens is now a vacuum, a theoretically non-existent "point", akin to what a black hole is in 3D space. The 2D "atom" in spot X was displaced, it entered 3D space and gained a new characteristic: its position along the Z axis. This 2D atom traveled along a new dimensional axis and it is now in spot X,Y,Z with respect to the 2D plane, Z being a perpendicular vector with two directions in this new dimension ("up" and "down", thinking that the 2D plane was parallel to "our (3D beings)" floor.
However, there must have been energy at equilibrium to keep the line being "ordered" in this state otherwise it wouldn't even be a line it would just be entropy. There is an infinite amount of energy in that system, and it is in equilibrium keeping the 2D plane nice and tight.
Now you poke an infinitesimally small hole and the energy holding together this one little void in place has to go somewhere (this is when it is "pushed" to another dimension, transferred to 3D). So because there is a vacuum in this new void, the rest of the system energy forms pressure to fill this whole, like the pressure that a bubble would experience at the bottom of the ocean. And like a chain reaction, each "pull" generates another one and it propagates to both ends of the 2D plane. A jerking motion. Up to infinity on each side of the line. This is a two-dimensional wave that propagates through this "line universe" because there only exists a "line" vector, circles are only visible from the third dimension.
I need someone to confirm that they understand this so I can explain the next part, an explanation of sound and light waves. Please tell me this makes sense to you or why it doesn't so I can delve deeper.
