Logic here...

It's a game.

Cause fuck logic.

The minecraft workd isnt actually infinite.... Its approximatly 14 trillion chunks that can be generated.

it's not infinite, it's somewhere around 36 trillion (maybe billion) blocks squared, and assuming each block is 1 meter cubed it's still several thousand times bigger than earth

It is a game

The logic behind this is that the sun is a pixellated piece of Code... Couldnt Come up with something original?

Unless there was infinite suns that pass over

And so often?

Does the sun orbit Minecraft, or does Minecraft orbit the sun?
