In 1989 I saw a slightly different proof that our earth is round 🙂
There are many ways to prove that our earth is round. But in 1989 I saw a phenomenon that proved our earth is round.
1989 Thanksgiving day. The 3 of us went to New Orleans to party hard.

After 3 days and 3 nights of partying, we drove back home.
We pass Lake Pontchartrain. This lake is shallow but large. From south to north about 39 km from east to west about 64 km. In the middle there is a highway above the water. As seen in the satellite photo.


And it looks like there is a high voltage electricity transmission pole.

Doesn’t it seem like the earth is round?

These poles are all the same height. but it can be seen that the pole bends downward according to the curvature of our earth.

.
So in 1989 I saw a new phenomenon (for me) that proved that the earth was round.
Enjoy and stay awesome.
