(Note after note on notes: After leaving Maui, things have been too chaotic to finish 2D, 3D, 4D, 5D Thinking Made Simple. It literally would gobble up my whole time and awareness to sort through it. The first section was written in a day non-stop literally from the moment I woke up until I went to sleep. The humor began with section two because I really did not wish to return to writing it after what it did to me the day before. I had blisters (I prefer to use pens). I had way too much I should have been doing else, and hated going back to working on it. I knew it was a black hole timewise, and again, absolutely loathed working on it but also could not not, so the humor was basically to cheer me up along the way. I cannot afford timewise to give over that much of my life at once to such a project, so while traveling and preparing for school I have been jotting down notes on 5D which is where it was heading to after 4D was winding down. Inventor was brought back briefly from the dead (after I missed my flight and had a few extra days) to explain trispinning or spinning on 3 axises at once but never got around to it.  I would not want to spoil his batting average by going back to it without adequate time, and because 5D will be a lot  harder to explain, though I do regret not doing trispinning. Trispinning is cool.) 

What must be said about some of these notes. Don't expect some parts (there are many different types of notes) to make much sense. Some are just bits and pieces of thought. Some makes actual sense but 5 dimensions of space or 4 dimensions of space plus time does not seem to make a lot of sense, even when it is written correctly and explained well. If you understand 4 dimensions of space without time, you are at the point I started at this point. Without understanding 4 dimensions of space well, you won't even have a point of reference in what is very deep and murky waters of 5D. I won't claim that this plumbs those dark and murky waters successfully or in shedding any light into them, but it is an attempt, and if  you are up to speed on 4D, you might appreciate the attempt.

Getting up to speed on 4D. Read every book about 4 dimensions of space, then forget them because they don't know what the heck they are talking about, but at least then you will understand the basic concepts and be able to do the following. Build mentally a picture of a Tesseract in your head made out of hollow cubes instead of solid cubes. Enter one of the cubes, while it is being assembled and make doors so you can wander between them. After wandering around awhile you will notice you are in curved space, like the surface of a hypersphere only more angular. Curved 3D space is like "closed" 4D space, because it must be curved into 4D space, and is less confusing that "open" 4D space. It is 4D space with 3D rules, like the 2D surface of our 3D planet abiding to 2D rules. Our world is curved into 3D space but we know 2D rules or space equally as well because we are not Superman and cannot leave the "surface" 2D world easily. 

Once you are done understanding 4D space's "surface" which looks a lot like 3D but with really weird turns and aspects of being here and there at the same time, you can now take your Tesseract you have been wandering around in and stack it with another Tesseract to begin building a 5D version of a cube or Tesseract. Now things get really weird. Whereas before, though not exactly always sure where "here" really was relative to there, while you kept moving and did not think too much about it, you could see the rules. Intertwined Tesseracts have different rules. Stacking them, even just 2, is to begin a 5D structure in which its "surface" is curved 4D space, or 5D space with 4D rules, which is way easier to understand than "open" 4D space. Only that small part of where the two Tesseracts meet is like "open" 4D space, and then it has to still follow rules. The more rules you can make 4D follow, the easier it is to get a handle on it. 

Again a planet is really 3D but at the "surface" but we can understand the 2D rules of being confined to a 2D surface which is curved into a 3rd dimension. You can easily get a grip on the inner workings of a Tesseract by wandering around in one because it is like the "surface" of 4D which is a lot like 3D but with some really strange curves between the doors, like the curves 2D people would experience around a cube's surface. Make the curvature smooth with every step and you have a hypersphere, a 4D circle or sphere. You may not be able to fly off into 4D space yet but you would understand a 4th dimensional curvature, as 3D space with some exceptional curvings which are somewhat weird. Now by stacking 2 Tesseracts, you are moving up to curved 4D into a fifth dimension, but it is really only pure 4D where the 2 cubes intersect. The rest of the structure still works the same as the one you should have been wandering around in for awhile now and completely understand it. If you don't understand the internal structure and relationship of a Tesseracts cubes to each other, don't proceed until you do. In that one cube where the 4D objects meet and intermingle is curved or "closed" 5D space or "open" 4D space with a weird curve thrown in, but still obeying mostly 4D rules. At this point I had to make a graph to understand movement through the partially 5D structure. 

Where would each door lead to if not to the same pattern as before in a normal Tesseract? How far would you have to go to get back to the same cube? What would be the new pattern? These were easy to figure out after about a day but the pattern required something new. 2 different spaces over lapping or 2 different measures of time. From the cube you came from in the center of the junction cube you could either go in one direction or the other. Trying to graph these movements is impossible without adding either forward/backward space, or forward/backward time. It does not matter what you call it, but you do have to add something you might not have considered before to keep track of where you would end up, how you got there, and where the next door would take you. And now the notes.
