What is the name of the lava filled dimension you can travel to via a portal

The Nether is the name of the lava-filled dimension you can travel to via a portal.

Explanation: The Nether is a liquid, like measurement, loaded with flame, magma, and hazardous crowds for a Mine craft game. To get to the Nether, the player must build an under entrance in the Over world (entries made at last don't actuate). To make the gateway, the player should initially construct a rectangular obsidian outline, extending in size from at least 4*5 to a limit of 23*23. When the casing is manufactured, it would then be able to be enacted by putting fire inside the casing, utilizing rock and steel, fire charge, allocators or any materials.
