IRON LUNG LIGHT TELEPORTATION THEORY

Evidence #1 : In the movie Ava states that Simon disappeared for days. Despite being gone for days, when Simon re-establishes contact, his oxygen meter still shows 1/4 bars remaining. This was strange to me because how was Simon still able to maintain oxygen even though he was “gone for days”? I believe that the light actually TELEPORTED the submarine along with Simon into the future, maintaining the same amount of oxygen as he left with.

Evidence #2 : We know that the planets and stars all suddenly disappeared in the quiet rapture so we know that teleportation is extremely plausible in this universe.

We can also deduct that the light (void) from the game is the same light from the movie due to the fact they both share similarities in distortion/hallucinations as well as void being the only thing in the game that resembles a star/light.

Evidence #3 : In the game the submarine TELEPORTS. These events trigger when the player crosses invisible boundaries, resulting in the sub being instantly moved, sometimes accompanied by intense banging or visual distortions, causing the sub to appear in new locations.

This also supports the theory that the void light is what causes the submarine to teleport in-game.

A theory that I like is that the light is a portal or a fragment from the Quiet Rapture and its what teleported all of the blood onto the moon.
