It's about as long as The San Francisco earthquake of 1906
(1906) (Mussel Rock Fault, California) (sensible duration)
The San Francisco earthquake of 1906 caused perceptible shaking of the ground for about 52,500,000,000 nanoseconds. The most devastating natural disaster in California's history, the quake was felt as far away and southern Oregon and western Nevada, and resulted in about 3,000 deaths, the displacement of 55% - 70% of the city's population, and the shifting of some spots of ground by up to 6 m (20 ft).
It's about four-and-a-half times as long as The First airplane flight (Wright Flyer, 1903)
In other words, 52,500,000,000 nanoseconds is 4.4 times the length of The First airplane flight (Wright Flyer, 1903), and the length of The First airplane flight (Wright Flyer, 1903) is 0.23 times that amount.(Wright Flyer) (1903)
The first successful airplane flight was made by Orville Wright on December 17th, 1903 and lasted 12,000,000,000 nanoseconds, covering a horizontal distance of 37 m (121.39 ft). The stopwatch used by Orville and his brother Wilbur to time this flight is on display at the Smithsonian National Air and Space Museum in Washington, D.C.
It's about seven times as long as a Pit Stop
In other words, 52,500,000,000 nanoseconds is 7 times the length of a Pit Stop, and the length of a Pit Stop is 0.1 times that amount.(for IndyCar racing; optimal)
A well-executed, IndyCar racing pit stop takes just 8,000,000,000 nanoseconds. Changing all four tires takes about 3,000,000,000 nanoseconds.
It's about one-fifteenth as long as The First spacewalk
In other words, 52,500,000,000 nanoseconds is 0.07 times the length of The First spacewalk, and the length of The First spacewalk is 14 times that amount.(1965) (Alexi Lenovo, a.k.a. Алексе́й Архи́пович Лео́нов)
On March 18th, 1965, during the Voskhod 2 Soviet space mission, cosmonaut Alexey Arkhipovich Leonov conducted the first human spacewalk, which lasted 720,000,000,000 nanoseconds. The total mission length was 94,000,000,000,000 nanoseconds.
It's about one-twentieth as long as Louis-Antoine's reign
In other words, 52,500,000,000 nanoseconds is 0.1 times the length of Louis-Antoine's reign, and the length of Louis-Antoine's reign is 20 times that amount.(a.k.a. Louis-Antoine d'Artois, petit-fils de France, fils de France, duc d'Angoulême, a.k.a. Count of Marnes) (1830)
Following his father, Charles X's, abdication on the eve of the 1830 French Revolution, Louis-Antoine d'Artois was technically king for a period of approximately 1,000,000,000,000 nanoseconds on August 2nd, 1830. Louis-Antoine's only official act as king was to abdicate the throne to his nephew, the Henri, the Duke of Bordeaux.
It's about twenty times as long as The First movie
In other words, 52,500,000,000 nanoseconds is 24.9 times the length of The First movie, and the length of The First movie is 0.040 times that amount.(1888) (Roundhay Garden Scene, National Museum of Photography, Film, and Television restored copy)
Filmed in 1888 by Louis Aimé Augustin Le Prince, Roundhay Garden Scene is the oldest surviving motion picture with a total running time of 2,110,000,000 nanoseconds.
It's about one-fifty-fifth as long as a Basketball game
In other words, 52,500,000,000 nanoseconds is 0.018 times the length of a Basketball game, and the length of a Basketball game is 54.9 times that amount.(NBA regulation; playing time only)
Per National Basketball Association rules , a basketball game (without an overtime) consists of four periods of 720,000,000,000 nanoseconds each, for a total of 2,880,000,000,000 nanoseconds of playing time. The first basketball game, played in a Springfield Massachusetts YMCA, was played in 1,800,000,000,000 nanoseconds and ended with a score of 1-0.
