Turtlie

Turtlies are any number of cosmological objects, vastly ranging in size from sub-universal to universal, based on the famous saying, "it's turtles all the way down". They can a collection of lower-level Turtlies, being made of even smaller ones and so on, except if they are the lowest-level Turtlie, the Planet. Higher-level Turtlies are always made of the previous level, except if they are a Planet.

There is also a measurement system used by many civilizations within The Infinite Cosmology that starts with T-0 (Planet), T-1 (Star System), etc. This is a set of values corresponding with their objects:

Pre-Normal Turtlies[]

These turtlies is class 0 or lower classes, so they is not big. At orders, they are reversed (highest is -1, lowest is -ω).

Turtlie Tier	Standard Naming	Size	Note
Tier -1	Moon	500Km - 5,000Km	The variants of moons. They orbit not every turtlies tier 0 (planet)s.
Tier -2	Continent	100Km - 500Km	They not apper on every planets.
Tier -3	Country	5Km - 100Km	Contries may be over 100Km, meaning they is at size of tier -2, tier -1.
Tier -4	Town	1Km - 5Km	They may not appear in every Contries.
...	...	...	...
Tier -ω	Protoverse / SMOLverse	0m	They can be found in uqraek fibers.

Normal Turtlies[]

These turtlies is high class 0 objects. They even class 1 objects.

Turtlie Tier	Standard Naming	Size	Note
T-0	Planet	5,000Km - 100,000Km	This is where we live in, until the far future. (around 2500s - 3000s).
T-1	Star System	100Gm - 50Tm	Star System can have any amount of stars, up to 3 rarely!
T-2	Galaxy	5,000 LY - 10,000,000 LY	Type 3 civilizations can control over this entire system.
T-3	Galaxy Cluster	50,000,000 LY - 200,000,000 LY	This may be the limit of our civilization, no matter how far you go.
T-4	Galaxy Supercluster	250,000,000 LY - 1,000,000,000 LY	Galaxy clusters are grouped with other clusters in superclusters.
T-5	Hypercluster/Supercluster Complex/Galaxy Filament	1,500,000,000 LY - 10,000,000,000 LY	This is only the observed level where there are some unique types.
T-6	Tublaxa	50,000,000,000 LY - 500,000,000,000 LY	The common universes can't have Tublaxas because they're not big enough to fit one. Only "bigger universes" can.
T-7	Tublaxa Cluster	1.0010¹² LY - 1.5010¹³ LY	Yeah... It's a generic cluster of Tublaxas. Nothing's special.
T-7	Tublaxa Supercluster	5.0010¹⁴ LY - 3.0010¹⁵ LY	Nothing special, it's just a generic cluster of Tublaxa Clusters.
T-8	Tublaxa Hypercluster/Tublaxa Supercluster Complex/Tublaxa Filament	7.5010¹⁵ LY - 5.0010¹⁶ LY	Very big universe or multiverses can contain it only.
T-9	Universal Tublaxa	2.7510¹⁷ LY - 9.0010¹⁷ LY	Universes can't contain this, but multiveres can contain it.
T-10	Universal Tublaxa Group	1.0010¹⁸ LY - 5.0010¹⁸ LY	Bigger Multiverses can contain it.
T-11	Universal Tublaxa Cluster	6.4010¹⁹ LY - 2.0510²⁰ LY	There very low odds that Multiverses can contain it, so Megaverses commonly contain it.
T-12	Universal Tublaxa Supercluster	1.7510²¹ LY - 1.4010²² LY	Megaverse can contain it.
...	...	...	...
T-∞	Ultraverse / Infinityverse	∞ LY	Omniverses or Higher can contain it. Sometimes archverses or infinityverses contain it.
...	...	...	...
T-ω (Limit)	Universe / Erkesik	ω LY	Omniverses and allomniverses can contain it. This is also included to the outside or higher.

The Turtlie ranking system is has the same essence as the EUSI, the differences being, that the Turtlie counts the amount of nested systems, instead of physical containments, and doesn't include an array as its input.

The Turtlie rank should theoretically begin with T-0 being a moon, but not all planets have moons, and if we include moons, there is nothing stopping moons from also having moons, and triple nested moons, and so on. This could theoretically be described as $T-(-\omega)$ , but the author didn't intend for this originally, so it is unofficial yet.
