After all, the curvature of space-time is not an absolute value but a relative one.
Liu Feng calibrated the Space-Time Clock to zero using Space-Time Particles during The Fourth Dreamland.
That is to say,
From now on, whether the curvature of space-time increases or decreases, it is all judged relative to The Fourth Dreamland.
Lin Xian understood it this way.
The further one strays from the world line of The Fourth Dreamland, no matter positively or negatively, the value of space-time curvature should increase. For example, both -0.0000336 and +0.0000336 are the same distance from the 0.0000000 world line, with one being negative and the other positive.
Continuing the reasoning.
What are the standards for positive and negative changes?
Since the curvature of space-time is a simple two-dimensional figure, any change is either a positive increase or a negative drop.
At present,
