Moving between dimension

[Blaze]

I'm sure that this has come up before, but It's been bothering me for a while, and I wanted to write something about it.

in 2D space, Fred (As the example in the explanations/theories written), only comprehends the directions of Forward, Back, Up and Down. He can move in all of these directions, and anywhere between. (I.E. Up and forward or Down and backward)

He has no comprehension of Left and Right, but if he were to somehow come upon the information that such directions existed, he would, with no doubt, try to push himself in said directions. If Fred could learn to push himself left and right, he could lift straight out of his 2-dimensional world, thus gaining an infinitely small width to himself, allowing him to be in realmspace.

So if we were to come across the information of such directions as Upsilon and Delta, could we not be able to push ourselves in said directions to lift ourselves straight out of Realmspace and into Tetraspace?

It's a bit far fetched, but if Fred could somehow understand left & right, could we somehow understand Upsilon & Delta? (Or their real 4-dimensional names respectively?)

Thoughts anyone?

The concept of up and down requieres the previous existence of a center of a gravitational force. In our pure space for an astronaut there is not up or down. Also there is not up or down in a free fall situation. So Fred, in his two dimensional world needs to sense a permanent force in a fixed direction or for him there will be not up or down. In the text that definition is missing. The author or persons in charge of that page in what Fred is born, must establish that definition. That is simple and can be done easily. If not, the reader will be absolutely lost and the explanation, fundamental for any new reader, has no sense.

It is, for simplicity's sake to suppose that gravity and time exists in every space, and that essentially that things in foreign spaces experience up/down [gravity] and front/back [time = motion], in much the same way that we do. The mistake that many people make with ana/kata is that the extra dimension is orthogonal to absolute direction, is thus to relative ones. We have left/right but in four dimensions, there is nothing to fix a prefered axis orthogonal to up/down and forward/backwards. You can readily demonstrate this by setting clocks on the floor of a room. The room is a map of a 4D room. The face of the clock represents wall-flowers at a dance. You make them face into the room by placing the clocks face up, but what force do you align the numbers of the clock to point the same way?

Moving between dimensions, is mor akin to the reptiles in Escher's print of the same name who crawl in and out of the paper. In any case, we see that we need to acquire extra body to move from movie to movement. Still.

What would he push against?

It was established on Alkaline's original website that Fred lives in a 2D world with gravity.

Dear friends:
In the first picture of Fred, Fred is triangular (why not eliptical or circular?), and has only one eye but two arms and two legs. This seem to me is an unnecesary limitation imposed by his Creator, not by the bidimensional space Fred lives in. I think that the two arms look better in front of him if Fred has no right or left... But Fred can have two eyes in front of him and must have two in order to be capable of distinguish if a line is near or far away in his flat world. Also in this first picture of Fred the author write Fred can see a circle. That is imposible in a flat world. Fred can only see lines. Fred see a line (the front half of the circle) because the other half of the circle is behind the front half). Of course the Creator of Fred can see the circle from the third dimension, over Fred...! But if Fred has two eyes in front of him and a brain (stereoscopic cerebral construction of a bidimensional view like us in our tridimensional world) he can know, not to see, from the distance, if a line is straight or curve ( concave or convex). But Fred can never see a circle like us from overhead... Fred can walk a circle "up and down" if he can levitate in his bidimensional space. The circle for Fred is like a solid sphere for us. Fred can not get out of a circle...or inside a circle...But can go a up and down a circle, not around...I insist in this simple things because the first ideas, hypotesis and assumptions will be crucial in the long run. We are playing Gods...! with Fred. We must be very carefull from the point of view of our third dimension. And remember we are always over Fred and his two dimensional world that can be an infinite geometric flat plan (?)( I do not like the word "infinite") or, better, a finite but boundless spherical very grand surface imbed in our superior tridimensional world.

You are correct
2D beings can only see lines, but not closed curves or plane like us 3D beings. From parallax, they can see a line and PERCEIVE 2D depth, and can only see the front part of 2D shapes. But not the whole thing at once. Therefore fred can only see a line with gradient appear from nowhere (the circle) in his world.

if you think 2D beings is not a good assumption (like what my dad thinks) Think projecting a 2D shape (e.g. circle) onto a line in perpsective projection . You'll get a gradiented line


Fred's world is a 2 manifold , which the surface is 2D but the whole thing can be >2D

We are playing Gods...! with Fred.

Fred doesn't really exist. He's a character, not a real 2D person.
