This layer of space is very thin, no more than twenty kilometers up or down.
If the cosmic space is considered as air, the curvature subspace can be regarded as the water surface, and below the water surface, there is an ultra-heavy organic solvent layer that is more structured and more completely isolated from the three-dimensional space.
The layer of space that Freddy discovered is the interstitial layer between the water surface and the ultra-heavy organic solvent, which has both the partial properties of the upper water surface and certain characteristics of the lower solvent.
Freddy called this interstitial space the mirror layer.
Both the objects in the water and those in the lower solvent can be projected onto the mirror layer and imaged.
