So i was i found a video on youtube that answers one of my biggest questions of minecraft. Is the world of Minecraft truly infinite???

Isn't the world of Minecraft as big as Neptune?

I have a theory that all singleplayer maps are connected so it is practically endless.

How does this man know this? Did he travel what was it 30,000,000 meters just to discover this? How long would that take?

My guess is he used commands to TP himself out till he hit the edge he talked about. The problem is the larger your world is the larger your jar file becomes. I wonder how large of a jar file a completely rendered world is?

Minecraft does actually end. Online servers generally cap out the max distance a player may travel since they only have so much RAM they can use to support you, and whatever amount of other players. Singleplayer servers however expand almost forever, or so the illusion is. According to the wiki, the algorithm must stop around 30,000,000 blocks away from the center block of the map. That is a long way. Back before they refined it, a player could visit the end of the map known as Far Lands, which was a space in the server script where the game would twist and contort due to physical limitations of scripting.



Now that minecraft has been out for awhile, the programmers fixed the twisty blocky Far Lands into almost a pure illusion. Around the edge of the map are known something as shadow, or fake blocks. These look like almost any other block, but you cannot break them or step on them. A normal moded player would be stuck at an imaginary wall, and or fall to their death instantly in the void. Players executing creative mode or fly hacks could possibly go further, but you would either run into the same situation as the normal moded players, or corrupt the server map and your character forcing it to shut down permanently. Also, whether you're gamemode 1'd or not, by the time you get to the edge of the map, just due to the sheer size of the file at that point, you become extremely laggy.

How I did it: Using a teleporting mod on singleplayer.

I still say its Herobrine....even though he's not real and most of e time is Corruption messing with people. :P
