Minecraft wiki entry for Void, associated text: Falling at least 64 blocks (i.e: under Y=-128) into the void causes the health of any mob (except the ender dragon) to be depleted by about 4 every 10 game ticks (0.5 seconds), leading to the player's death in 2 1⁄2 seconds. Armor, totems of undying, the Resistance effect and the Protection enchantment does not protect the player from dying in the void, and death occurs at 263.1 blocks into the void. Other status effects can alter the death level slightly. After this, if no buttons are pressed, the player usually falls to death at just over 256 blocks into the void, with this number varying on each death. It is possible to survive in the void if the player constantly eats enchanted golden apples. However, the only way to have enough of them is to have a command block constantly giving them to the player. The player can also survive in the void by having Regeneration or Instant Health of a sufficient level (achievable only by commands). If commands are used to make the player invincible or bestow infinite health, the player falls until Minecraft crashes. A player who falls into the void on a server with anti-flying measures is kicked out regardless of having a flying mod. Riding a vehicle into the void results in the player being stuck in the vehicle until death. The void extends for 21024 blocks (1.07×10301) on the Y-axis.
