Curvature Earth facts
While investigating facts about Curvature Earth Calculator and Curvature Earth Per Mile, I found out little known, but curios details like:
Roman aqueducts took into account the curvature of the Earth.
how high to see curvature of earth?
The first man-made object to reach the stratosphere was a meter long shell fired from the Paris Gun, used by the Germans in WW1 to bombard Paris from 80 miles away. The curvature of the earth had to be considered when calculating where the shells would land.
At what altitude can you see the curvature of the earth?
In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across answering at what height can you see the curvature of the earth. Here are 20 of the best facts about Curvature Earth Per Kilometer and Curvature Earth Formula I managed to collect.
what is the curvature of the earth?
-
The Verrazano-Narrows Bridge, a bridge whose support towers are so tall and far apart that, due to the curvature of the earth, are almost two inches farther apart at the top than the bottom.
-
The bullet that killed the longest confirmed sniper kill in history (3,540 m) flew for 10 second and and was flying for so long that the sniper had to take in the curvature of the Earth into account.
-
NYC's Verrazzano-Narrows Bridge's design has to account for the curvature of the Earth. The towers are 1 and 5/8 inches further apart at the top than they are at the base.
-
The curvature of the Earth led US surveyors to put curves/bends in roads every 24 miles
-
Due to time-dilation and Einstein's theory of relativity GPS satellites in orbits high above the Earth, where the curvature of spacetime due to the Earth's mass is less than it is at the Earth's surface require the internal clocks to tick at a faster rate than those on the ground.
-
The reason why the very long and straight roads in the U.S have random curves/ zigzags is to correct itself against the curvature of the earth.
-
The tops of the Humber Bridge's two towers are further apart than their bases, due to the curvature of the Earth.
-
Flying under the radar" is when the curvature of the earth is between you and the nearest radar station.
-
Grid corrections, places where North American roads deviate from their otherwise logical grid lines in order to account for the curvature of the Earth.
-
The Bedford Level experiment, which tests the curvature of the Earth, the results of which the author claimed proved the Earth to be flat, and is still used to support Flat Earth theory today.
Why can't you see the curvature of the earth from a plane?
You can easily fact check why can't i see the curvature of the earth by examining the linked well-known sources.
The top of the Golden Gate Bridge is almost two inches wider at the top than the base because of the curvature of the Earth
The Boeing Factory in Everett, Washington is so large that the curvature of the Earth had to be taken into account when the factory was being built. - source
How little the curvature of the Earth seems to change with altitude - source
Rapper Bobby Ray Simmons Jr, better known as BoB believes that the Earth is flat.He argued that if the Earth was curved, evidence of that would be apparent when looking at the horizon in the distance and distant cities would be hidden from view because of curvature.
About Joseph Kittinger, who was "the first man to fully witness the curvature of the earth" when he set the world record for highest skydive - source
When can you see the curvature of the earth?
U.S. road grid corrections occur every 24 miles because of the Earth’s curvature - the roads that follow these boundaries must dogleg every twenty-four miles to counter the diminishing distances.
