I see what you're saying, but I was thinking of actual distance, not just what can be seen.

No if the earth was flat you would be able to see all the way to the edge. With a round earth the higher you are the further around the curvature you see.
Wouldn't the distance to the horizon be different on a hillside than it would be on a flat plain?
Actually, it would. Imagine you're on a perfectly flat sphere (in a vacuum, of course). You can see out to a certain distance (it would circumscribe a line of latitude, assuming you're sitting at a pole). As your elevation increases (for no clear reason, a thin mountain is forming beneath you), you can see further and further out. As you head for infinity, you will eventually see the equator.
13? Kilometres? That's oddly specific... I smell an atheist conspiracy!The straight line of sight distance d in kilometers to the true horizon on earth is approximately
d = sqrt{13h}
where h is the height above ground or sea level (in meters) of the eye of the observer.
It would, but it's generally not taken to be walking distance, but rather the degree of latitude you can see down to (assuming a perfect sphere). Plus, even if you did do walking distance, a small increase in elevation corresponds to a massive increase in the distance-to-the-horizon: being flat on the ground, the distance is zero, while being 6' up, the distance is measured in miles.But since you have to walk down the hill, doesn't that add extra distance?
Do you have a better one?good physicist answer
Aliens. Or magic. Or magic aliens.
The 1500+ posts beg to differ. You ask a question, and I attempt to answer it. The premise is one of physics ("Why does ice float?"), but any questions are welcome, as are anyone's attempts at an answer.i guess there's not much point to this thread
My first, tho water, cures no thirst,My next alone has soul,And when he lives upon my first,He then is called my whole.
A pat on the back for anyone who can solve this riddle.
Here's a clue (highlight the text to read it):it's a single word, two syllables, and the riddle is referring to said syllables

That's itOoh ooh ooh I know this one!
Is it?seaman
You got the first bit right.I didn't get the second part of it - my solutions were.seafood and seatrain
All the more reason to get a proper theme, none of these poncy neon jobs.Actually you can use [spoiler=My Title]This is Hidden[/spoiler]
To create this
This is Hidden
As White Text shows up quite nicely on some of Themes
All the more reason to get a proper theme, none of these poncy neon jobs.
Also, I'm liking those 'noparse' tags, that'll make it handy when I'm educating ze children.
I take it you can't use the 'spoiler' tags on their lonesome, then? You need a?
