Trivia

 * The Nether Reactor will become obsolete (useless) after the Nether is added.
 * Lava in the Nether flows faster than in the Overworld.
 * It was widely believed the Nether would be added in Update 0.11.0, however, it was not.
 * It is possible that Zombie Pigmen will become neutral when The Nether is added into the game.
 * One block in the Nether equals 8 blocks in the Overworld.
 * This makes travelling the Nether an efficient way to move across the overworld.
 * You can NOT place water in the Nether.
 * Although, the only way to place water in the nether is to have a Cauldron and put the water in it.
 * You can build the nether portal up to 23x23 Obsidian blocks.
