The situation is this -- You are standing on the ground, which is entirely white, and it streches away from you in every direction to infinity. The ground is perfectly flat (you are not on a planet). You are one meter high (for the sake of simplicity). The sky is blue. Where exactly would you see the horizon? I'm not sure if gravity would affect the answer, but if it does assume a g of 9.8 m/s^2.

At eye level, neglecting physical effects like the speed of light, gravity, etc.

...unless you're strongly myopic (and not wearing any eyewear), then don't expect to see any horizon at all!

(just fuzzy sky blue and white... Extreme Delectation )

Ehhh...take it from me, as someone whose been myopic throughout almost my entire life, that condition does not grant any special abilities so far as seeing the Horizon is concerned.

The fuzzy sky blue and white horizon is mostly accurate I think, even if we say that we're in a perfect vacuum, but unless we say that this imaginary world has existed infinitely long, wouldn't there always be a thin fuzzy grey line between the blue sky and the white 'earth'? (This line would represent those photons that had not yet had time to travel from the distant 'horizon' to our eye.)

Astigmatism will produce that same effect. *nudge*
