My beloved boyfriend has made an observation about Jules Verne's work.
His musings were as follows:
Conversion
1 nautical league = 5.556 km = 3.45234 miles
20000 leagues = 111120 Km
The diameter of Earth = 12742 km.
(111120 - 12742)km = 98378km
The distance from Earth to the moon is 363194km at perigee and 405696km at apogee, therefore the average is 384400km.
At average;
(384400 - 98378)km = 286022km
Therefore we can conclude, that the novel “20000 leagues under the Sea” should take place about a quarter of the distance between the Earth and the Moon
Thus, it is a novel about Space Exploration.
