First dimension, forwards and backwards, second dimension, left and right, third dimension, up and down. But what about the fourth dimension? Is it time? Is there something else?
In a one dimensional world nothing can move left or right.
In a two dimensional world nothing can move up or down.
In a three dimensional world nothing can move….?
What would movement in the fourth dimension be? The fourth dimension to some people is considered time. Time is a movement that allows other movement. Without time movement in the other dimensions would not be possible. But what if there was another dimension of movement? Let us pretend time is the fifth dimension and the fourth is something else.
In a two dimensional world nothing can move up or down, so a three dimensional object would effetely disappear when moving up or down. Using this logic a four dimensional object would appear invisible when travelling in the forth dimension. The human body is three dimensions are we have eyes that can see two dimensions with depth to allow semi three dimensional sight. We cannot see all three dimensions, what if two dimensional objects can only see one dimensions. Using this logic we can presume that a four dimensional object with visual sight can see three dimensions.
Four one dimensional lines linked together form a two dimensional object as in a square. Six squares linked together form a three dimensional cube. Again using this logic what would happen if cubes formed together? The answer has been named on Wikipedia and Teamikaria. The answer on Wikipedia was Tesseract and means an eight cell cube. The answer on Teamikaria was a cubinder. Some of these shapes are pretty scary such as the Duocylinder when seen rotating. Is this because they are impossible or just impossible in our world?
Shadows from a two dimensional object are a line or a one dimensional object. Shadows from a three dimensional object are two dimensional. Again using this logic it would a safe to presume that a four dimensional object would project a three dimensional shadow.
All the above is just ideas to think about. What if there is another dimension and we just cannot see it or sense it. Our three dimensional objects cannot sense a fourth dimension because they just are not made to sense it. What if we learned to travel into the fourth dimension would we just disappear?
In my opinion the fourth dimension is the inside and outside. But of a fourth dimensional object. What if we could travel in and out of our world? Think of a line then give that line another line crossing into it. That line is not a cross. That is now two dimensions now move a line up and down from it. The line is now three dimensions. Now draw another line through the inside and out the other side. The result cannot be achieved. The idea is that if something could go inside and outside we could not see that object travelling inside or outside just know it had. I do not understand it myself and it is my opinion.
