I would use both marks, but that might be just me.
All this astronomy talk reminds me--while watching Jeopardy yesterday, I found out I had completely forgotten that Mars has two moons! How did I forget that?! I felt like such a dunce for thinking that Earth was the only one of the inner planets with a moon.
How did I forget that?!
Well, they are pretty small.
I'm a fan of the interrobang!??!?!?!!! but I have no idea how widely accepted it is among professional grammarians.
Would electrons "fall" out of their orbits, lacking any energy to "orbit"? Would all that empty space in an atom go away, as the atom sluggishly contracts upon itself?
Wouldn't they just be in their lowest energy states? They don't really orbit.
I have a question about the dangerous subject of punctuation.
Is this in the WIP, Gud? With dialogue, I'd use a question mark and then either use a dialogue tag to add the emphasis (like "he yelled,") or, since that's not actually one of my fave techniques, I tend to prefer adding emphasis to a word within the sentence with italics:
"What the frak is wrong with you?"
To me, that gives the impression of an exclaimed question. Generally, I think using both punctuation marks is frowned upon. But that's just me. YPMMV
Huh. I just discovered a fresh scar above my waist. It stung in the shower, like I'd recently been cut there. I have no idea how I got it.
I think I fought a ninja in my sleep.
"What the frak is wrong with you!"
I'd do it with just the exclamation point since the question is rhetorical and not meant to be answered. It's more like an interjection. That is, you say it with excitement (or emotion) rather than as a query.

My theory: an alien implant.
Have you had any "lost time" recently?
