Since some snapshots it's possible to tp to great (and sometimes wrong)Y axis distances.

Usually, the game won't let you teleport past Y:256 , but I've randomly tried to teleport to a really far position...And the game made it.
Example:

/tp @p ~ 67567485687667446564353457678909789667535645323567567342533454567567 ~

Second thing: You notice that the position you have chosen to teleport is not the same where the player spawns if you see on the F3 menu.

The used RAM floats from a certain number to another , and it makes a cycle.This cycle slows down when you get higher
From random (extremely high) distances it isn't possible to move in the Y axis. But you can still move on X/Z or just teleport to move on Y.
It is noticeable that sometimes Sky is only colored with one color, you can't see the color changing.
In other positions, Sky creates a three-colored nice effect : Example,if you are at night, there are : orange (afternoon-evening) on the bottom , light blue (nearly day) on the middle and Dark blue (night ) on the top.
It is nice to see these "High- Far Empty Lands" , but I still think why the game lets me do this impossible tp.
Third thing: In some positions world border won't work, and you can fall from those positions.In other positions you can't fall, but it is not worldborder 's fault, it is the great position that makes it buggy, since from 2 billion 147 million etc... the world border stops working.

If you want to fix it, then fix.But I still think this high buggy world is nice and makes a mistery-sensation.It isn't laggy 😃
Also, trying to reach 99.999.999. ecc... (9 wrote 71 times) will teleport you to 10^75 ,but the game will say 10E81, which means game will count 5 zeros more than the shown coordinate.

UPDATE
Since of 14w27a , TWO SUNS APPEAR when you go to Y:10^75
It now kicks you out after some minutes.

Yeah, i was messing with that in command blocks and i got it to teleport to y=999999999, and i needed to wait like 15 minutes to fall down... in 1.6.4 java 8 using command blocks

Confirmed.

Updated.On the maximum Y coordinate, 2 suns appear.Also, after a while it kicks you.It even redirects you to multiplayer screen.

The apperance of two suns is not a bug. If you go to such a high coordinate, the ground is unloaded. The chunks usually hide the moon, but now since they're unloaded the moon shows. It appears to look exactly like the sun during day. If you maintain ur height and set the time to night, you will see that the moon is on top and the sun is below, the sun having a yellowish halo around it, just like the sun during normal sunset. The "second sun" you see during day is actually the moon

also above 2^1024(~1.798E308) the y coord will say infinity (you cant just write 1.798E308 for /tp, you have to go to 1.797E308 and use relative coords to go up to "infinity")

Confirmed in 1.8.2-pre6. Similar behavior occurs at very low Y coordinates.

Confirmed for 15w44a.
Relates to MC-53510.

Note: Couldn't reproduce being unable to teleport to high altitudes. This should be intended.


Some additional information I found:

• I found out the highest altitude of which you're able to move in the Y-axis. It's interestingly enough the specific number of Y=4503599627370496.

  1. /tp ~ 4503599627370496 ~

    You won't be able to fly with creative mode over that height. It's like a roof. You are able to fly down. Y=4503599627370496 seems to be the highest point you are able to fly to.

  2. Now test

    /tp ~ 4503599627370497 ~

    and try to move in the Y-axis. The only way of moving is by falling, you can't fly in creative to move.

• When you teleport over Y=100000000000000000 the F3 menu begins to show inaccurate Y coordinates(mostly by changing the last four digits). This relates to what the description says (teleport to 10^75 but F3 shows 10E81).

• Over Y=10000000000000000 there seems to be a delay before the coordinate updates when you fall from there.
The highest point you can go to and at same time the coordinate updates when you fall is Y=36028797018963972, which takes about 3 seconds to start updating after you fall.

  1. /tp ~ 36028797018963972 ~
  2. Fall. Observe the Y coordinate.

  3. /tp ~ 36028797018963973 ~
  4. Fall and observe the Y coordinate again. It won't update.

• The lowest point you can get outside the world border is at Y=2147483645.

  1. Be inside the world border.

  2. /tp ~ 2147483644 ~

    and then try to get outside the world border by looking at your coordinates.

  3. /tp ~ 2147483645 ~

    You'll see that you can go through the world border by some blocks.


  1. Phew. This was a lot of pointless info! 🙂

SunCat

In 16w33a you get a message that the number must be at most 4096. I think it's fixed

migrated

Actually this was already fixed before 1.10.
