Philosophical Question: Does an end portal create an identical copy of you and kill the original? Or does it teleport you unharmed? via /r/Minecraft

Philosophical Question: Does an end portal create an identical copy of you and kill the original? Or does it teleport you unharmed?

CGP Grey investigates some troubling concerns about science fiction transporters (https://www.youtube.com/watch?v=nQHBAdShgYI). He asks: when you teleport, is a new copy of you made on the other side and you are killed? Or do you actually teleport so that it's really you on the other side and not some imposter? He goes on to wonder the same thing about sleeping.

For fun I decided to answer these questions in minecraft by looking at the code. Here's what I found:

  1. Teleportation to the end and the nether /do/ kill your player and create a new character in the other dimension (here, kill means that your entity has its 'isDead' property set to true).
  2. Teleportation via chorus fruit and ender pearls /does not/ kill you.
  3. Sleeping /does not/ kill your player.

Makes you think twice about the lava under the end portal… Sleep tight!
