Dimension

Dimensions are accessible realms within a Minecraft world characterized by a way of generation, biomes and structures, and other things unique to one dimension. Players can explore and discover various dimensions in Minecraft, typically through the use of portals. With the addition of data packs, players can make custom dimensions to explore in Minecraft.
The daylight cycle and weather may work differently or not exist in different dimensions, as well as respawn points (such as beds and respawn anchors).

== Other dimensions ==
=== Custom dimensions ===
* - The dimension definitions in custom worlds.
* The dimension and dimension type folders of data packs.
* Custom dimensions without the use of mods or data packs, using an NBT editor to modify a level.dat file containing an existing world and merge it with another world using the WorldGenSettings nbt data. Accessing your custom world would need to be executed in the custom dimension with commands.
=== Unimplemented dimensions ===
* - The unimplemented dimension that would have contained floating land masses and was planned to be added in the Adventure Update.
* Dream Dimension - A briefly mentioned unimplemented then-Pocket Edition-exclusive dimension.
=== Joke dimensions ===
In joke snapshot 20w14∞, about 2.14 billion (2^31) dimensions were added. These only existed in 20w14∞ and were not kept in later snapshots. There were also several easter egg dimensions, each having their own unique feature. The other dimensions were completely random.
In 23w13a_or_b, there is a dimension called the Moon. It is accessed by the player launching themselves high enough.
In 24w14potato, there is a dimension called the potato dimension. It's filled with various poisonous potato blocks, and it has potato structures, potato mobs, and even has it own unique biomes. It is accessed by an activated pedestal, which can be found in the portal ruined portal (which generates randomly in the Overworld), and can be activated by right-clicking with a poisonous potato on the hand.
The potato dimension has no bedrock or bottom so if an entity falls, it will die from the void.
