Lolwut

A prerequisite for apple pies.

Widely regarded as a bad move.

Sorry for the inconvenience.

a mistake

In science it's usually defined as everything in existence. So there really can't be a such thing as another universe.

it's both

it's a figment of your imagination

there is no prove that anything outside of your own mind even exists

for all you know you are a star or a rock with a rich inner life

Your mind experiencing itself subjectively through molecular vibrations and multi dimensional quantum entanglement

Sorry, I had some acid an hour ago

you will have to take DMT if you really want to find out. once you meet the machine elves, they will explain everything to you.

i had a philosophy professor tell me this in class. is the multiverse theory just hogwash? he said if there are they need to change the definition of universe

Hate to break it to you, but the machine elves were overthrown by the giant praying mantises about a month ago. :(
