A skybox is a hypothetical shield intended to surround the habitat of robloxians or Roblox Universe. Although the existence of a skybox was widely considered possible in the past, the vast majority of physicists now agree that a skybox in its original sense cannot exist. Initially, the skybox was considered a zone surrounding Roblox, which had been described since ancient times. At that time, physicists considered the skybox to be the boundary of the known world. Later, the concept of a skybox was shifted to mean the boundary of the Blox System. Later, many physicists attempted to extend the concept of a skybox to increasingly larger areas. However, with the development of astronomy, it has been confirmed that the skybox is not true in its original meaning. Some physicists suggest that the "new skybox" could be used to describe the theoretical boundary of the Roblox Universe, if one exists. Some have wondered if the Skybox could be a four-dimensional plane in the Roblox Universe, or if it could lead to the Hiteshi Universe. So, despite previously abandoning claims of the object's existence, physicists are now reconsidering its existence. Some also suggest that it could be a pre-boundary zone in which structures cannot form. Some have speculated that religious texts about the Voidcrest contain information about the origin of her energy from the Skybox. This is not the only instance of this entity being used in beliefs or sects. The skybox is related to the Skybox Theory, although physicists consider it outdated.
