If "The Hitchhikers Guide To The Galaxy" isn't true, why is the Answer to the Question of Life, the Universe, and Everything '42'?
...BTW, I've figured out the Question to the Answer. The LGBT symbol is the Rainbow, correct? It represents unity of all people, regardless of race, nationality, gender, politics, creed, and sexuality/lifestyle (as per Dr. King's 'Dream'); all it takes is for certain people to eliminate from their minds certain attitudes preventing said unity.
Now, what is the angle required for a rainbow to appear, post-rain shower (and bright sunlight, for said microscopic droplets suspended in the sky for the necessary refraction process)?:
42°
Ergo, the Question: 'What is it that brings true universal Unity, via it's symbol - and the viewing of such in it's natural form?
QED.
No 'Earth II' required. Sorry, Slartibartfast (loved your fjords you got an award for, BTW!).
