Is it possible to see the curvature of the Earth?

, physicist unhinged. Yes, you can see the curvature, but not directly – the visible signs of curvature are subtle, somewhat rare, and it requires a bit of reasoning to interpret these visual effects. The earth itself appears flat to the naked eye – where the land is flat!

Is the Earth curved or flat?

This is clear evidence that the earth is curved. Maybe it doesn’t prove the earth is spherical, it could still be a disk, but does prove that the earth is not square or cuboid, and it does answer the question — when we have a lunar eclipse, you can see the curvature of the earth with the naked eye.

Is it possible to see the curve in the sky?

Many of us have had similar experiences when perched on cliff tops and looking seaward, but is it just our minds playing wishful tricks? Scientists say that anyone flying at 35,000 feet on a clear day and with at least a 60-degree field of view will be able to discern the curve.

Why can’t we see the horizon curve left to right?

It’s not possible to see the horizon curve left to right in your field of view from any height achievable by most people, the earth is just much too big. The cruising height of a U2 spy plane (70,000ft) is only a tiny fraction of the earth’s diameter (42 million feet).

What is the threshold altitude for seeing the earth’s curvature?

Studies place the threshold altitude for seeing Earth’s curvature at about 35,000 feet. Earth curves at about 8 inches per mile, but the distance one can see depends on height.

How far away can you see the earth curving?

Earth curves at about 8 inches per mile, but the distance one can see depends on height. For a six-foot-tall person, the curvature is approximately 3 miles away. This is a geometrical finding since the human eye cannot see a 24-inch curve from 3 miles away.
