The possible meaning of "42"

Indeed. The abbreviated story is that he was at his desk and staring out the window, into the garden and thought 42 will do.

While there is a little more to the story and some history behind it, it's not much. Douglas Adams has refuted all of them; this one, 6x9 in base 13, street addresses, something about Tibetan monks... all false.

Typical asumptive revisionism.

I remember there was one about the way you pronounce 4 and 2 in japan and it is the same word for death, therefore the meaning of life is death. I thought this one was true but I guess it really was random..kind of a bummer actually. Unless this is a false claim as well

Yes it is.
"Forty-two will do," as he stared into his garden was as far as it went.
