In Earthlings' minds, String theory was something that required many extra dimensions to perfectly explain everything.
But at its root, what String theory described was the motion of one-dimensional strings projected into (3+1)-dimensional space.
Three spatial dimensions, one temporal dimension.
All parameters for particle positions were included within the spatial dimensions, while all parameters for intervals between changes in particle states were included within the temporal dimension.
If one wished to incorporate gravity into a model, then that model had to achieve this.
Therefore, although String theory required many extra dimensions—
Those curled-up dimensions existed only to better describe this motion.
At its root, the motions described in higher dimensions also had to be projected into (3+1)-dimensional spacetime.
Otherwise, they would completely fail to conform to human understanding.
It had to be noted that this was not four-dimensional space.
Within the known range, nothing could truly move through time.
If something really could move through time, it would become a time machine.
Yet the entire universe showed no signs of having developed a spacetime vessel—at least, no being at the Dragon Emperor's level knew of one.
Even if such a thing had existed in the era of the Celestial Great Saint, it could not possibly have been opened to the Celestial Favored Clan.
Otherwise, when everyone sought transcendence, they would not have been farming or destroying the Dao; they would have joined forces to search the universe for spacetime vessels.
Spatial dimensions and temporal dimensions had to be strictly distinguished.
Lu Xiaoqian froze. "This... are you sure you didn't misread it? The cultivation methods of the Fire Folk rarely involve spacetime. Or rather, they simply have no need for techniques of the cosmos."
Su Junyu narrowed his eyes. "But this really doesn't look right."
"But this spell definitely doesn't involve
