Higher than four-dimensional?
What does that mean?
Yu Liang didn't understand; this kind of thing was presumably beyond the comprehension of ordinary people.
In general understanding, one, two, three dimensions refer to length, width, and height, while the fourth dimension refers to time. Then what about the fifth dimension?
Point, plane, block, then time; what comes next?
Yu Liang was not a science student; he could not fully grasp what a higher dimension really was.
He had heard of something like 11 dimensions, such as the "two-dimensional unfolding" and "high-dimensional folding" mentioned in "The Three-Body Problem," but those concepts were too abstract for him—they simply meant—
There are that many dimensions?
Two-dimensional unfolding and high-dimensional collapse and such, these terms sound very highbrow, they'd be great to incorporate into a novel to increase its trendiness.
