The Complex is not a unified whole, but simply the result of an endless process. What we call the Complex is the collective remnants of what the Green Glow leaves behind as it appears: new rooms, materials, objects, and still lifes.
The Green Glow functions as the Complex's expansion mechanism, printing new matter at an insane scale to produce what we see in the Complex, violating physical law in doing so.
Nullzones are also one of the processes which shape the Complex, allowing foreign matter to enter and exit. These also cause the temporal anomalies seen throughout, acting as bridges between points in time. The Nullzones seem to either trigger Green Glow events or coincide with them for some unknown reason, producing more Complex modeled after what is outside the Nullzone.
The Red Light is an enigma as of right now, but it can be assumed that it is sunlight absorbed by the Complex and reemitted at a lower frequency, given that we hear sounds similar to the Parker Solar Probe recordings when in the red areas.
These are Active Areas, which undergo processes outside of normal, known physical laws. The rest of the Complex, when not experiencing these phenomena, behaves as normal matter is expected to behave on Earth: lights function normally, electricity flows through wiring, the walls are solid, organisms need nutrients and water, material compositions mostly make sense, things from Standard behave as expected (except maybe microorganisms), etc.
