'thought experiment' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'good in chain store with cd-rs distributed' is the wordplay.
'good' becomes 'g' (abbreviation).
'in' indicates putting letters inside.
'with' is a charade indicator (letters next to each other).
'distributed' indicates anagramming the letters.
'chain'+'store'+'cd'+'rs'='chainstorecdrs'
'chainstorecdrs' anagrammed gives 'schrodinerscat'.
'g' going within 'schrodinerscat' is 'SCHRODINGERS CAT'.
