The Fourth Dimension

Following the Collectors' idea, the Celestial Mechanism Megastructure first simulated an absolute cube in three-dimensional spacetime, then began importing high-dimensional transformations.

The absolute cube was then transformed into tens of thousands of "points." These countless points formed the absolute cube, with every point representing a coordinate.

In the Collectors' conception, applying high-dimensional transformations to the values of every coordinate point would ultimately yield a three-dimensional object in higher-dimensional spacetime.

When the high-dimensional transformation formula was imported, the Collectors saw the absolute cube spread out like a pool of liquid. A plane slowly unfolded, upon which they could simultaneously see the cube's four corners, twelve edges, six faces, and its interior and exterior in three-dimensional spacetime. It shifted like a kaleidoscope.

"It became a plane."

Although the Collectors had largely guessed that, according to the formula, a solid object would collapse into a lower dimension, not every individual possessed an imagination rich enough to picture what a three-dimensional cube would look like after collapsing into a lower dimension before the Celestial Mechanism Megastructure simulated it.

It had to be said that the flattened three-dimensional cube was dazzling, like blooming petals. Were human women from Earth or female Selin to see it, they would surely be unable to resist becoming enthralled.

"This is the conversion into the fourth dimension. In the fourth dimension, one can see all of a three-dimensional object, just as a three-dimensional being sees a two-dimensional plane."

Since this was only an experimental simulation, the Collectors had no intention of simulating dimensions that were too high. They only had the Celestial Mechanism Megastructure calculate as far as the fourth dimension. From this fourth-dimensional perspective, a three-dimensional object was a plane without thickness.

"But in reality, purely lower-dimensional objects cannot exist. Take the Ze Trees, for example. Their cognition is
