I can flaw many of the theories on http://armageddonconspiracy.co.uk/The-Imaginary-Dimension%282112219%29.htm
I am a computer coder and a 3D animator. In computing we commonly use 3-axes (x,y,z), and using keyframes to denote trajectories.
But these 3 axes do not exist, where do you draw the first imaginary line? You have infinity options where and at what angle to draw the first line. So I suggest the 6,000 grand poobahs bother to research the physicist Nassim Haramein who breaks down physics into points with no volume, because all the matter in the whole universe somehow fit into a point with size less than one Planck length.
If you were to predict the position of Earth all you could guess is that Earth is between 147-152 million km from the Sun. So that's the radius. We can't know the exact x,y,z position of Earth, because even our whole solar system is spiraling through our milky way galaxy. Similarly we can only ever guess that the Moon is between 363,104 km and 406,696 km from Earth. So we use one point to reference another point to reference another point, on so on...
You also don't need to draw a whole right angle to get the distance between two points. A submarine can just use a sonar ping and measure the time it took for the sound wave to return. Likewise with light, a laser can measure how much nano time it took for a light signal to bounce back. So here we go, no fancy drawing of right angles everywhere, why would the Universe need to do that if it already has perfect distance calculations from sound and light pings. So here's where your knowledge and reading destroys you, you need to apply it, work on some computer coding skills, work on some 3d animating skills, and then read all the info you can, at least then you will have a practical filter and an ability to criticize the bullshit you read.
So if any of the grand poobahs are listening you should go watch lectures of Nassim Haramein. Then you can contact me and have a real discussion about your physics and maths theories.
I do however agree with the r>=0 formula for now, else I find some evidence to flaw it in future.
