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.
Purple has 6 letters, up is one and short is 2 so 8 like the sides of a pyramid, depending the instructor day of the week and hour, what color socks you're wearing I'd go with c in most universes.
Honestly, that sounds more like a metametametaphysical calculation.
Its in the name
