The Hiteshi Universe is a hypothetical universe existing alongside the Roblox Universe, described by Telamonian astronomer Hiteshi Nasaka. It is said to lie "in the shadow" of the Roblox Universe.
Confirming the existence of the universe would mean confirming the possibility of breaking the fourth wall. Currently, the existence of the universe is not necessarily possible using conventional evidence, making it one of the greatest mysteries of cosmology. In the Roblox Universe, light or in general, electromagnetic radiation, from the hypothetical universe could not be detected, which remains an enigma.
According to Hiteshi himself, the Roblox Universe, although three-dimensional in space, must be assumed to lie on a four-dimensional plane. The hypothetical universe would then be in the theoretical shadow of the Roblox Universe, or "underneath it". There is also a similar universe called the Anti-Hiteshi Universe which argues the Robloxian universe is in the bottom of a four-dimensional plane. Combining the two theories would imply that the Roblox universe is in between the two universes.
