This may or may not blow your mind.

MCYT IS NOT A MULTIVERSE. HEAR ME OUT.

My theory is that every Minecraft world ever created is just a planet, all within the same universe.

That's right, EVERY MINECRAFT WORLD/SERVER/REALM EVER CREATED EXISTS IN THE SAME UNIVERSE.

AND YOUR WORLD IS IN THE SAME UNIVERSE AS ALL OF THE BEST SMPS IN THE WORLD.

And when you delete a world or die in a hardcore world, that planet is wiped out by a supernova or a meteor or black hole or somethin. 

Since the irl universe is believed to be infinite and contain billions of planets, this is entirely possible.

Also, if you guys know your basic geology and earth science, you know that the earth has 3 main layers, the crust, mantle, and core.

I believe that;

Overworld- Crust

Nether- Mantle

End- INSIDE THE CORE

IT MAKES SENSE. FOR ONCE IN MY LIFE, I MADE SENSE.

I love astronomy and I want this to be Minecraft canon. It has to be.

Comment questions if you have any. I guarantee I will be able to answer them.
