Well, I think there is no question. This would explain how 42 can be the answer to éverything. Off course, there's a little problem here, since 42 allegedly is the answer. Answers usually are the response to questions right? But perhaps it was meant more as 'solution' to a problem and '42' being the 'answer'?

I mean, what would even be 'the question about everything'? If 42 is the ultimate answer to the question that matters most, then how can there even be a question? A problem would somehow make more sense in my opinion.

Cheers
