How to Get a Black Hole in Minecraft
This small command adds in two new items, the pocket black hole and the Gravitation Sword. The pocket black hole is a miniature black hole that sucks in all mobs around it. It won't affect the player unless the player stands in the middle of it. Don't do that or you will die lol The second item, the Gravitation Sword, summons in a black hole above you whenever you hit a mob. Press shift and walk a little to fling mobs close to you into the air! Have fun with this command guys! Keep an eye out for more! - Mordial33
How to install
How to import this command into your world
First, you must give yourself a command block (If you are on a server, you must be 'OP'ed, and have access to /gamemode 1)
To get a command block, type /give @p command_block in the chat.
Once you have a command block, right click it to open it's GUI.
Now, you must copy and paste the command from your browser into the game. Select the entire command from below, then right click and press 'copy'.
Next, go back to your minecraft world, and paste the command you just copied into the command block. There are a few different keys that may be used to do this, depending on your keyboard. The most common ones are 'CTRL + V', 'COMMAND + V', or 'STRG + V'
Finally, you can press done to exit the GUI, and execute the command block by powering it with a redstone block, a lever, or any thing you can get your grubby hands on. Just make sure you don't place it on top of the command block, or the machine will not be installed!
