It's known that traveling one block in the Nether is equivalent to traveling 8 blocks in the real world, and I can confirm that along the X and Z axes by building four portals: two in the Nether and two in the real world.
But I can't seem to corroborate the length dilation from the Nether to the real world along the Y axis (height).
That is, if I build the following portals:
- Portal 1 at n height
- Portal 2 at n - 8 height
- Real world:
- Portal 3 at m height
- Portal 4 at m - 64 height
I expect Portal 1 and 3 to link up while portal 2 and 4 should link up. But in my testing, if I use portal 1 or 2, they lead to portal 3, and if I use portal 3 or 4, they lead to portal 2.
Is there any evidence—in the form of a video, a world save file, or notch—that one nether block equals 8 real world blocks along the Y axis? I'm trying to determine if my error is in calculation or if it's in execution.
