Beyond the Robloxian universe is a theory that postulates that there are other Robloxian universes and skyboxes with different diameters, some of which are so small that their laws of physics will allow those universes to have distances smaller than a Planck length in the Robloxian universe. As of 2026, this theory is not yet proven due to multiversal travel not yet demonstrated in even a peer-reviewed journalistic article, and as such, is widely accepted as a fringe crackpot theory among peer-reviewed scientists along with the more famous Skybox Theory.
Universes are distinguished in this theory as a medium verse and a Planck verse, with former universes being larger than the Robloxian universe and latter universes being smaller than the Planck length in the Robloxian universe. It is said that the set of all Robloxian universes is known as the Robloxiverse.
Classification:
Medium Verses
The Robloxian universe - The known verse of everything and reality, it is considered the Prime Universe of The Robloxiverse. As of 2026, this is the peer-reviewed maximum where Roblox is said to truly go and Robloxians are able to reach unless a peer-reviewed journalistic article proves otherwise with multiversal travel. (Size: 93B ly)
The Roblox Multiverse - Contains Robloxian universes. (Size: Depends on how many Robloxian universes there are.)
Combining with the theory that the Robloxian universe is simulated, this implies that the Roblox Multiverse has a diameter of math.huge studs.
Roblox Megaverse - Contains The Roblox Multiverse, including more Multiverses. (Size: G100 ly)
Roblox Hyperverse - Contains The Roblox Megaverse and more Complex Megaverses. (Size: G1,000,000 ly)
The Roblox Outerverse - Contains The Roblox Hyperverse (Size: BIG FOOT ly)
The Robloxiverse (Omniverse) - This is the true maximum where Roblox is said to truly go, and where Robloxians limits are said to reach. (Size: w^w^2 ly)
Planck Verses
Roblox Verseuni - Size: 1.22e-9 planck lengths.
Roblox Versemulti - Size: 5.52e-18 planck lengths.
Roblox Versemeta - Size: 3.55e-33 planck lengths.
Roblox Versexeno - Size: 6.33e-50 planck lengths.
Roblox Versehyper - Size: 2.55e-80 planck lengths.
Roblox Verseultra - Size: 5.42e-100 planck lengths.
Roblox Verseomni - Size: -0.5 planck lengths. At this universe, if a Robloxian were to be going there, they would report that space has inverted.
Criticism:
The Beyond the Robloxian Universe theory has been the subject of widespread criticism among peer-reviewed scientists due to the theory being a spinoff of an existing fringe theory, namely the Skybox Theory. The article of the theory when it was first published was retracted in many peer-reviewed journals for containing unverified information, and peer reviewers commented that there is only one Robloxian universe. They however, acknowledged the possibility of multiversal travel, but until a replicable peer-reviewed experiment to transport between universes can be found, it would always remain as a fringe Robloxian theory.
