Curvature of the planet earth

Drive the Causeway.

Can you explain what the causeway is ?

seent it before, and I was in a seat by myself

If you think about it..... China is the upside down.

I always thought they were sideways.

I've flown in airplanes across the Atlantic and I didn't see any curvature.

No, mathematically, you need to be at pretty good altitude...it's a trick of the eye if you think you see it.

You're about 40,000' too low.

and wth does being over the Atlantic have to do with it?

Can you tell from the naked eye the curvature of the earth

'tis a trick question.


There is no curve. The Earth if flatter than Keira Knightley.

That part I understood. The water, being ostensibly "flat", would present less visual noise than say, a mountain range, to mask any subtle curvature that might be visible from that altitude.

Seeing the power lines disappear as they cross the lake are not QUITE the same thing as seeing the Earth's curvature directly. You're not seeing the Earth's curvature, but rather the effects of the Earth's curvature. If those power lines weren't there, you wouldn't notice anything. It's kind of the same idea as standing on the shore of an ocean and seeing the sail of a ship on the horizon, then more and more of the ship as it approaches. You're not seeing the Earth's curvature directly, but rather the consequences of the Earth's curvature in the amount of the ship visible to you. The power lines across Pontchartrain are the exact same phenomenon.
