Minecraft wiki entry for Void, associated text: In Bedrock and Education editions, the player's health is depleted by 4 every half second at Y=-65 and below. At Y=-104 an invisible barrier is created, preventing the player from falling further. This barrier can be bypassed by using commands such as /tp, after which the player falls indefinitely until they crash the game or fly back up. In Creative mode, one does not die, giving free access to flying under the void. However, if the player goes to any coordinates beyond negative or positive X or Z of 8,388,608 blocks, the invisible barrier disappears due to blocks of any kind no longer being solid to the player (see Bedrock Edition distance effects for more details). A similar phenomenon can also occur at certain lower coordinates in some instances.[1]
