Things the Standard Model can't explain

There are others, of course, but this is a nice introduction.

1. Why do neutrinos have mass?
2. What is dark matter?
3. Why is there so much matter in the universe?
4. Why is the expansion of the universe accelerating?
5. Is there a particle associated with the force of gravity?

I'd probably add :
"Just what the hell are singularities, anyway ?"
"Seriously, WTF is going on with the double slit experiment ?"
"If I did travel back in time and interfere with the past, what would happen ?"
"What is the nature of a mental concept ?"
"What's it all about, I mean, you know, when you get right down to it ?"
