Photoverse

The Photoverse is verse, which is extremely compressed with photons. So much so, that any disturbance to the Photoverse 's size / compactness would instantly colapse the Photoverse into a black hole.

The Photoverse expands each second by its age (in seconds), in light years, the age of this verse is 13.7 billion years.

Due to this expansion, photons appear to slide in and out of existence, seemingly through a different dimension.
