How to Complete Subspace Bubble

Enter the Nether

The first step you need to take for the Subspace Bubble Advancement is to create a Nether portal. This structure needs at least 10 Obsidian blocks and a Flint and Steel.

Create a 4x5 frame using Obsidian (the four corners are not needed) then light up the inner part of the frame using Flint and Steel. Enter the portal by walking into the purple haze at the center.

Travel 875 blocks in the Nether

Before proceeding, make sure that you have enough Obsidian blocks with you so you can create another Nether portal that will take you back to the Overworld.

Once you're set, you can begin exploring the Nether for the Advancement. Since 1 block in the Nether is 8 blocks in the Overworld, you need to travel 875 blocks away from the portal that you created.

You can also push it to 1000 blocks, just to be safe.

Check your coordinates by pressing F3

Track your location by pressing F3 and checking your coordinates. Check the starting Nether portal's X position, then begin walking away until the number increases by at least 875.

Return to the Overworld

After covering a distance of 875 blocks away from your starting point, create another Nether portal, activate it, and return to the Overworld to complete the Subspace Bubble Advancement!
