Minecraft Planet: World Border Rework: A Cubic World with 90° Gravity Shift

Hello Mojang Team,I have an idea to completely fix the performance and floating-point bugs at the 30 million world border while adding an incredible new feature: Transforming the world geometry into a giant cube!How it works:The Normal World: On the surface, the world looks completely normal. Underground, it stays the same too—with caves, deepslate, and bedrock. You won't notice a difference until you reach the edge.The Edge (30M): When a player reaches the 30M border, they stand at a massive cliff where the world bends 90 degrees downward. Walking over it shifts the player's gravity by 90 degrees. The old wall becomes the new floor.The 4th Coordinate & Portals: To prevent mathematical floating-point bugs, the game introduces a 4th coordinate to the system: The Face Number (1 to 6). To make traveling between these faces accessible in survival mode, players can build or find special Portals that instantly change this 4th coordinate, teleporting them to another side of the cube.No More Bugs: Because the coordinates reset or count safely when switching faces, the game never suffers from floating-point precision loss.World Size Customization:
In the world creation settings, players should be able to change the size of this cube. This would solve the world border limitations and add a mind-blowing new mechanic to exploration and building.Thank you for reading!
