Here is a paradox for you, possibly not the sort of thing you're after, in the sense that it is a) all maths, nothing physical b) very easy to resolve but here it is anyway... x=1 multipy both sides by -1 -x=-1 add x^2 (x squared) to both sides x^2-x=x^2-1 factorise x(x-1)=(x-1)(x+1) simplify x=x+1 but x=1 so 1=2 (!!!) ANSWER: at first glance it may seem baffling, but closer inspection reveals all the manipulation is just in aid of hiding the fact that in one of the steps both sides are divided by zero, this is of course the hole on the proof. 0*1=0*2 does not imply 1=2 Like I said it's kind of basic, I thought you might be interested.
I was wondering about something. I assume you are familiar with transformation matrices, in particular those dealing with rotation. I have rotation matrices which rotate 3D objects in 3D space. I don't suppose you have rotation matrices to rotate 4D objects in 4D space (or formulae - one or the other). It would be a great help to the project I am currently working on.Another letter from Chris:
I am a young naive student who is very interested in the fourth geometric dimension (ie. not space/time). You mentioned that an accepted statement is thus: "Fourth Dimensional beings could not fit in the third dimension, as we could not fit in the second dimension, and thusly cannot visit it. Upon observation of our dimension, thses fourth dimensional bodies would consider it extremely simple. Just like the second dimension is simple to us." Surely this is not entirely accurate. If you imagine a 3D being (let's say a sphere - a living sphere!) and a 2D being (a square - a living square). Now, if this 2D being was just walking along one day in its 2D space, and suddenly this sphere came down from above and intersected with the 2D being line of sight, would this not make the sphere visible to the 2D being. Naturally, the 2D being can only see the 2D cross section of the sphere (since it would only have 1D (pseudo-2D) vision), and as the sphere descended down and through its line of site, the 2d creature would see its cross section - a line which starts of small (the bottom of the sphere) and begins to grow as the middle of the sphere intersects, then begins to shrink again as the top begins to intersect. Put in short, the 2-D creature sees 2 out of 3 dimensions that the 3D creature possesses. Now similarly, if a 4D creature visited us, then whatever parts of it intersect with out 2D (pseudo-3D) vision, we would see. Thus, we would see 3 out of 4 of its dimensions. Now if the 4D being we to turn around in our field-of-view, we would simply see those parts which intersected 3D space. It would look like bits of him/her/it phased in and out of [our] existence. Just a thought. I will send more of my points-of-view as I dive deeper into your site. I love it!!!
Every mathematiina needs an answer at parties to "What is the 4th dimennsion?" My short one is "I will point along it for you, on one condition. You must point along the first." `The' 4th dimension no more exists than `the' first -- they don't come numbered. If there's more time, and/or the person is someone I'd like to know better, I explain about waist measurement. Take the people at a big family reunion, young and old, all mixed. For each person you can collect their age and their height; if you mark each of them as a dot on paper, far from the left side in proportion to their age, and far from the bottom in proporition to their height, you get a cloud of points looking something like * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * (if you read this in a display with proportional spacing, my ASCII sketch will be badly messed up.) The cloud roughly levels off -- people get to a certain height and then stop growing (even shrink a little bit). Now add a third datum, weight (including reunion food, and clothes unless your family is more fun than mine). Just as people can have the same age and different heights, or the same height and different ages, they can have the same age and height and different weights, so this is a distinct dimesnion. The figure goes 3D; I can't do good stereo in ASCII, so you'll have to imagine point cloud. (Unlike height, weight does go on increasing with age.) Nothing very mystical so far. Now go around and measure people's waists. Two people can have the same age, height and weight but still have different waist sizes; so the data cloud becomes 4D, with thickness in this direction also. In this story, `the' 4th dimension is waist measurement. `The' first dimension is here time, the dimension along which we measure age. If you agree that Age belongs along the first axis in my 2D figure, you agree that time is the first dimension. Nu?

I am just recently getting into the whole theory of the fourth dimension but what i have began to think is that the fourth dimension revolves around a time line just like our 3d and 2d's do. We are to be concidered traveling in a line in time. We begin at one point, which no one knows when it is because we dont know how we were created, was it god? was it the big bang, but then what created the big bang? where does it all start? Anyways our time begins at an open interval on a graph and is continuous to an end. The end too may be an open interval because we can not say what happens after "death." IN the fourth dimension there is no "order" of time. It is all just scattered all over the place. BUT! how do i know if i have jumped ahead of time, or behind in time? do we age in 4d? if so then we HAVE to be following a time line, its just that in the fourth dimension we do not have to obey the RULES of the time line. Everything is planned out, pre-destined, so in 4d we can see what is going to happen and what has happened, yet we have no control over it. This is all beginning to make me think that our 3d is actually more of an enigma than 4d. In 3d we dont know what will happen, but why not? we just dont have the right "tools" to, in the fourth dimension everything becomes more set and we can run more freely in time but what is the point? we already know what is going to happen, in 4d we cant die, what happens to us? is this "eternity" thing what 4d is about. thank you darlene
Matter. It just moves There is nothing else but motion of matter. No motion takes place while time is running. No one ever has seen time running Is it right to conclude that when things are moving there is something like time running beside their motion? Something that allows motion? Motion is a result of force. what happens when things move is that particles change their distances to each other. „How fast?" asks for changes in distances compared to your measure motion: the watch. Velocity is explained without the slightest touch of time What is regarded as being a result of time is pure motion. The concept of time as a dimension to explain what happens is superfluous Whereas motion needs no time quite the contrary time is not thinkable without moving particles when we „detect" time with watches we compare motions motion can be thought and explained without a thing called time.
I've been sitting here browsing your web pages for about 3 hours and my mind is racing. It's been a couple years since I've been able to sit back and theorize about dimensions, time, space, etc. I really like the theories presented in your pages, as they represent basically the exact ideas that I have come up with for the same topics. I'm not sure if you are a spiritual person or not, or if you have ever read or heard about the Kabala, but I believe it may be of great interest to you. Without understanding of the concepts of higher dimensions, energy/matter relationships, etc., the religious ideas in the Kabala don't seem to make very much sense, but I've found that if I relate the ideas found there with scientific ideas such as those in your web pages, the dots seem to connect themselves. I can't remember offhand where I got the file, but a while ago I downloaded a file called Notes On Kabala (NOK.ZIP). I had read a few books on the subject before getting this file and was very intrigued, but the way the text in that file is presented, it becomes very easy for someone with scientific knowledge to understand how the concepts of the Kabala are more than just spiritual beliefs, but a guide to understanding the fundamental nature of everything. I'm don't know how busy of a person you are, but if, sometime, you are in a 'deep' thought mode and interested, I really suggest you try to find that file. I am very sure you will be able to use the information to form new ideas, which I someday hope to read on your web page :)
Great page guys! Wish I had your programming skills. Have a theory that might interest you. Seems to "fit" existing science, but simplifes everything fantastically. Located just down the street from you at CapeCanaveral/7986. Come on by..."roundabout" = floyd.
Hello. My name is Drew Colbert. I just wanted to share my thoughts about your topics. I have seen the movie Event Horizon, and while it is mainly a horror movie, it has a short bit on black holes, etc. It says that this ship, the Event Horizon, has an artificial black hole in it that forms a gravity well, therefore adjoining two points in space. It also says that when they are joined you pass through a portal to bring you to the other part of space. I probably no squat compared to your fellow theorists, yet wouldn't they be at the bottom of the gravity well, with several stellar objects bombarding the ship, if the black hole was activated inside the ship? As well the gateway is supposed to be through the black hole as people pass through it. That seems a little far-fetched. There's always going to be all of this dimension passing stuff with a purple vortex people go through in movies and other shows. They should really tell the facts. I would also like to comment about the speculation on negative speed. In most cases, anything negative is the opposite, yet decellerating is obviously not the answer. Dan's equation says that after infinity, negative numbers appear. So, for going -200 MPH, he might need to do 200 MPH faster than light, our universal infinity. Then -200 MPH might mean you go back in time to when you were going the speed of light, which was infinity. AW, what am I saying? Well, I have one question. How do you go through a wormhole? Is it near the black hole or straight to it? Do you disappear while being sucked in? I love your page and keep on posting theories.
Your page is probably very cool. I've read a few of the theories, and they're interesting. Unfortunately, I'll probably never go there again. See, your music plug-in overrides the volume control on my computer. Every time I go to a new page within the site (or even back to an old one), out come tunes of varying quality, blasting the innocent patrons of an otherwise peaceful computer lab - regardless of how I last set the sound controls. And nobody needs to hear "Twilight Zone" one more time. If you want sounds to automatically play, sure, go for it. I usually have my computer's volume turned off for that reason. But your program thwarts my desires and rages against me and those close to me. I know I'm not the only one who shares this sentiment. -Matt
First is to realize the shadow effect is really from the basic particles that make up your and my mass and the basic particles of the Moon and the Earth. The incoming basic particles mostly miss everything when going through the Earth. The basic solid core of the basic particles is like one to 90,000 times the effective diameter of the sphere of influence the basic particle has. So most particles go right through the Earth. Newton's calculus states the sum of the shadows of the basic particles of the Moon and Earth act as if they were all at the center of the Moon and Earth. If Newton's Calculus is correct, then the shadows and mass of the basic particles can be considered to act as if they were all at the centers.
Your powerful rocket achieves a velocity exceeding the speed of light within a few moments. Since that isn't possible, the question is absurd. The answer is everywhere! This is like the problem of localizability in theoretical physics. If the photon moves at the idealized velocity of c, no time passes for it and by quantum mechanics' uncertainty principle, it is in no particular position in the spacetime continuum; thus it is in contact wih every spacetime point of the 4 manifold. Every photon in the universe is in contact with everywhere in the universe. In order to avoid this enigma physicists like Dirac invented even stranger devices like delta functions which are infinite at a point but zero everywhere else. Some avoidance. Of course, we can introduce exotic geometries like wormholes to mimic the intent of your enigma 6, but these are hypothetical constructs that are fraught with their own absurdities. Also, we can lean on Special Relativity as you mention and talk about from whose perspective is the velocity being assessed. Relative to the rocket ship frame there is no theoretical limiting velocity. I.E. if you accelerate for a few years at the rate of gravity, you will achieve velocities far exceeding that of light. For external observers though you just shrink and disappear only to reappear at a distance slightly less than what it would take a photon to travel. The enigma here is can you beat a photon in a race. To this day this is a controversial issue and remains unclear. We have no knowledge of photon structure, what it means to move in the continuum, or even what is the continuum. Similarily we don't know what the constituents of the magnetic field are. At every level of physics even quark level where for practicality purposes the photon is asserted to be composed of a quark-antiquark pair in a specially bound state, entities like photon or magnetic field are assumed as infinitely divisible givens. You don't ask what they are, you only ask what they do. Some ontology. So, your enigma is wrongly posed, the idea is based on a wrong perception (semi-classical approximation), and what is really going may not be determinate at all. Now there is an enigma!
I have to argue your solution to the doubler enigma. The box would never be half full because in order to be so it would have to have an even number of balls to be divided into an integer. Since you can't have half a ball put into the box it will always contain an odd number of balls since the number of balls will be equil to the sum of 2^n as n goes from 0 to 360, for the # of minutes passed. The fact that one ball is added first makes the sum at every minute an odd number. As a result the box will be just a little more than half full at 5:59. Chris
First off, I agree that, of course, time cannot move at the speed of light. They are fundamentally different 'things' and time is used to measure velocity. Thus, it just doesn't work that way. However, you are forgetting Einstein's Relativity. It has been proven that the faster one moves, the more time slows down. If you reach the speed of light, there would be a complete conversion of matter into energy because mass increases as speed increases and energy use increases as mass increases. This can be represented by an asymptotic curve as one approaches the speed of light. Theoretically, that speed cannott be reached but if it were, it would require infinite energy, which would be the conversion of the infinite mass of the moving object. Anyway... If you are able, somehow, to move faster than light, a simple extrapolation from the equations shows that you would move backward in time. This is because velocity of an object affects the space-time continuum(as Einstein coined) in such a way as to curve time. On the other hand, if one were to reach an infinite speed, one would never stop, and I rather think that this would be detrimental to the universe as a whole, in that infinite speed would mean that you would be everywhere at once in the entire universe. Infinite speed, due to the warping of time and space by velocity, implies a singularity. Put the two together and you have the entire universe becoming a singularity, and this is, to say the least, a rather bad thing. :) That's all for now. Later! -Matt Miller
I also think in this manner. We only realize a line from one point to the next, but if we shift our position, the line shortens and we could consider it a shorter distance. It is only from the position of objects which are stationary outside of us that we can mark the actual distance of the line, using geometry. If space were curved, we wouldn't notice it. When we look at a star, we only realize it to be a line's distance away from us when actually the star could be a reflection on a gigantic mirror that's just outside our solar system. one could go so far as to infer that all of reality is just a mirrored reflection and this would fit in nicely with your theory. One could start travelling to a star and, for all we know, it could take only half a light year to reach, or longer than a calculated time/distance, because apace is curved in some bizarre way. The only way I think anyone will be able to say where things lie for sure is to experience them. In our physical world, this is near impossible because each individual lies directly outside everything else, but there is a way: astral projection is one way that I know of to slip into objects and experience them directly. I don't know. There has to be a better way. Mystery and Science are married, you know. If you want to, you can e-mail me
I have a couple of ideas on multi-dimensional shapes you may find interesting. The first is on the hypersphere. Now on your web page you state that we can't know what something in the fourth dimension looks like since, well, we live in 3 dimensions (R3). I have to disagree, and the reason why is because living in R3 gives us access to see things in R0, R1, R2, and R3; (for my point) being a point, line, circle, and a sphere respectively. With this we can see that four things happen as we go from R2 to R3. 1) A shape in R3 is made up of an infinite number of "corresponding" shapes in R2. 2) As the infinite number of R2 shapes extend out to the limit (here radius) of the R3 shape along the "new" axis they get smaller and smaller until they reach a point. 3) The infinite number of R2 shapes intersect each other in order to create the shape in R3. The intersection is actually an element of R1. Here it is a line which has been bent around to make a circle. At this point making a drawing would help. 4) As a shape in R3 passes through R2 an observer in R2 will see it as a shape translated to a corresponding shape in R2 starting as a point, growing to a maximum, and shrinking back to a point. Since these rules are consistent for jumping through the dimensions we do know, I find it reasonable to believe that they are congruent for jumping into dimensions we do not know. Therefore we can postulate that a hypersphere is made up of an infinite number of spheres who's intersection is a circle. Imagine a sphere of radius r with an infinite number of spheres (noted set 1) around its center who's centers are an infinitely small (here out noted dx) distance away from the first sphere's center. These spheres will have a radius of r minus dx. Each of these spheres in set 1 will have a sphere who's center is dx away from their center and who's radius is r minus 2dx. These spheres belong to set 2. This continues until we get to set infinity which is made up of spheres with a radius r minus infinity*dx, a bunch of points. The hyperradius of the hypersphere is dependent on the radius of the sphere which is in the center of it. And, what do you know, we have again a congruency since the radius of a circle yields the radius of a sphere. The first argument that I can think of to this is that it would appear that we have objects in the same space at the same time, but keep in mind that this "invasion of space" is actually acomadated by the extra dimension. The hypervolume of this thing would be the infinite sum of diminishing spheres from both ends of the new dimension times dr; that is, int (4*pi*r^3)/3 from -r to r dr = (2*pi*r^4)/3 Consider the argument I have for the quintichypersphere. It is much more difficult to understand this one but here goes... In keeping with the rules of congruency before mentioned we know that the quintichypersphere (qhs) is made of on infinite number of hyperspheres and that their intersection with each other is a sphere. If you have a picture of what a hypersphere looks like in your head already then we can go on. The center of each hypersphere will be dx from the center of the hypersphere preceding it until you get to the first hypersphere. Let's call the first set of diminishing hyperspheres from the center one QSet 1. This is analogous to the idea mentioned before. Since the hypersphere radiates out diminishing spheres to a point, we find that in the qhs the center hypersphere's diminishing spheres are circumscribed by the diminishing spheres of QSet 1, and so on. Again we have congruency with the assumptions made earlier. The volume of the qhs will be the infinite sum of the hypervolumes from both the positive and negative ends of the fifth dimension times dr. As you can see there is a pattern here. The volume of a multi-dimensional "sphere" where the dimension is greater than 3 is equil to 2^n-3 int (4*pi*r^3)/3 (dr)^n-3 from 0 to r, where n is the dimension we are refering to. Note that the wedge product is not used for dr, since if it were the nth dimensional hypervolumes would all be 0. In order to find the nth-dimensional hypervolume of a shape in dimension n one must find the volume of the "corresponding" shape in dimension n-1.; That's about it. Write back if you can. I'd like to hear some criticism on this. Chris Jurgenson.
