Little Details

I suppose it would depend on what kind of space ship one had and how fast it could go, but how long would it take to get from one galaxy to another?

If anyone could help me on this, that would be wonderful. I need it for a fic I'm writing. The fandom is Stargate: Atlantis, if that helps.

I don't know whether this has been posted before or not, but yeah.

Who among you have witnessed a sonic boom? What does the plane look like? Is the wind-skirt-thing real, like the ones in cartoons? And what does it feel and sound like? Any personal opinions about supersonic aircraft are appreciated too.

Thanks in advance. ^_^

Which would cause less harms: falling down the stairs vertically (head over heals) or horizentaly (on one's side)?

What is the actual cause for the shiver you feel when you hear a particular piece of music or when you see something disturbing? We all know the feeling, that tingle that goes out the arms and down the legs. Is it an adrenal rush or what?

Okay, I'm writing a story for Prince of Tennis, and can't seem to remember something.

You know Nanako, Ryoma's cousin, right? What does she refer to Momo as?

Thanks in advance! <3
