I Went to the 4th Dimension in Minecraft Hardcore

Summary

SB737 attempts to reach Minecraft’s hidden “ghost dimension” in a long-running Hardcore survival world. The dimension is accessed through a version-specific glitch—not mods, cheats, or commands—but the process risks corrupting world chunks and losing items. Because he must downgrade to Minecraft 1.12.2, he stores his belongings, then gathers new gear and materials while trying to stay alive without armor or totems.

Preparation and journey

After downgrading, SB737 rebuilds his supplies from scratch, collecting iron armor, food, diamonds, obsidian, redstone, gold, gunpowder, and Ender Pearls. He travels to a stronghold, enters the End, and uses its predictable location in the downgraded world to reach the portal.

In End cities, he finds an Elytra and Shulker Boxes. He then resets the End as part of the downgrade process. This destroys his End megabase, but allows him to fight the dragon and use the cleared space for a large contraption.

To gather the gold needed for the contraption, he builds a 1.12-style gold farm. Pigmen spawn on layered platforms, are drawn toward him, and fall into a central hole. He repeatedly aggros them and uses a Looting sword to collect gold.

After an unexpected trip back to a newer version to escape the Nether roof, he carefully preserves essential items through another downgrade. He also gathers slime, chorus fruit, and extra supplies.

Building the update suppressor

SB737 builds an update suppressor, a large redstone contraption that rapidly updates powered rails and disrupts normal game behavior.

He removes the End portal frames using a dragon-egg-and-piston technique, allowing him to enter the portal sideways rather than falling through. When the first attempts fail, he removes nearby blocks and restarts Minecraft. After restarting, the glitch works.

The ghost dimension

Entering the glitch leaves SB737 in a strange limbo state, with his items temporarily disappearing. Eating chorus fruit then transports him into the ghost dimension.

The dimension contains bizarre floating or mismatched terrain, including mushroom blocks, lava, water, fire, ravines, vines, and what appear to be pieces of mineshafts. Many blocks are “ghost blocks”: they can disappear when right-clicked, but cannot be collected when broken.

Placing a block can fill an entire subchunk with that block, creating huge cubes—for example, giant diamond or gold formations. These formations appear to be inaccessible as resources.

Movement and physics are unreliable: the Elytra and rockets do not work normally, and SB737 sometimes gets stuck or experiences inconsistent fall damage and collision.

To return, he selects Save and Quit to Title and reloads the world. He reappears at the corresponding End coordinates. The process can be repeated while he remains on the relevant game version.

Key risks and tips

• Back up or safely store valuable items before downgrading. Inventory, Ender Chest contents, enchantments, and chunks may be lost or changed.
• In Hardcore, prepare armor, food, spare tools, and a safe route before entering dangerous areas. One mistake can end the world.
• Bring chorus fruit, since it is essential to the dimension-entry method.
• Be careful with Endermen while building in the End, and conserve Elytra durability and rockets.
• If the portal glitch does not trigger, restart Minecraft and try again.
