I had a couple of hours to kill in the bath and decided to try and answer the unanswerable question – and found out pretty quickly why it’s considered unanswerable. Nonetheless, I came up with my own crude answer, and I’ll try to summarise the key points of my reasoning here.
Disclaimer: I have not read anything at all on the subject. This entire train of thought has probably been conceived of and subsequently debunked a thousand times before! I’m just a kid with some time to kill and a few ideas.
