1D sphere

[Ashim]

First density means "dead matter" or "mineral life". The sphere has not cultivated complex molecules for plants and biological life.

yes and "locked" means kept in that state by an external influence.
Ie, a hollowed out planet used as a space station.

Perhaps sent into an excentric orbit as the result of a stellar incident.

then there are countless of moons, astroids, comets and planets in the universe that locked in first density.

To be "locked" requires those who do the "locking".

Most celestial objects could be seen as developing, only some being "locked".
