The question is “If up is down and short is long, what is purple?”
the choices are:
a: red, short wavelengths become long
b: indeterminate, up and down being equivalent means at least one spatial dimension has disappeared, compressing mater into disks that will collapse into black holes and also changes electrodynamics
c: logical contradiction, the universe ceases to exist and there is no purple
d: just wait for the drugs to wear off.
I think d has to be a trick answer, since it is too obvious. But I don’t remember the lectures covering logical non-existence or 2D universes.
Obviously C
You can’t make an omelette without breaking an egg, and you can’t ‘invert’ the spatial dimensions of an egg without breaking the universe
makes sense, it’s like Sagan said. “To make an apple pie from scratch, you must first invent the universe” but in reverse.
