The mankind cannot draw 4 dimension space this kind of view is a bit one-sided, because 4 dimension space is major,the person cannot understand for certain, but do not eliminate somebody to be able to understand. The 4 dimension space that we think at present is the three dimensional space that we live + time, we use naked eye is cannot direct observation of 4 dimension space, so, even if can drawing 4 dimension space also cannot see. Have kind of hypothesis that depicts dimensional dimension to spend, assume there is biology of a kind of planar on a piece of paper, it can move inside planar plane only, its with a casing casing lives, it will not escape, also cannot choose to escape from upper part, cannot imagine because of it and describe a true three dimensional space, because it cannot enter three dimensional space, is true three dimensional space what kind of it cannot is informed.
To our mankind, three dimensional space we can be described with planar brushwork, if use 2 dimension brushwork to describe 4 dimension space, differred two dimension to spend among them, this is just like a picture linear (one dimension space) will describe three dimensional space, how be accomplished? Anyway I also imagine do not come out. The mankind serves as the biology of three dimensional space, increase dimension of a space to spend, actually very fathomless, for the angle that spends from dimension, dimension is spent even if the description nods a needed the smallest coordinate to count, if we want to describe the object of space of a 4 dimension, so the issue came: What does the 4th dimension spend this to express?
We do not know of its measure is what quantity after all, same, any N dimension biology encounter same question in the metropolis when trying to imagine N+1 dimension space. But pass umbriferous be to be able to draw 4 dimension graph, exceed cube for instance: An acme is linking 4 pillar. Our universe may be as high as 11 dimension to spend, because this wants to clear up total mystery of the universe, estimation mankind wants him first somewhat developmental.
