SortStack #375 — 2027-06-19

By duration · Order from shortest to longest.

1. A single sneeze, from sharp inhale to achoo 1.5 sec

   A sneeze can launch droplets several metres, and you can't sneeze with your eyes open without effort — the blink is part of the reflex.

2. The world's longest scheduled flight, Singapore to New York 19 h

   The route covers about 15,300 km. The aircraft is configured with no economy class at all — partly so passengers survive the experience.

3. The Apollo 11 mission, launch to splashdown 8.1 days

   Of the whole voyage, Armstrong and Aldrin spent barely 22 hours on the lunar surface — and only about two and a half walking on it.

4. The Islamic holy month of Ramadan 29.5 days

   Because it follows the lunar calendar, Ramadan drifts about 11 days earlier each year — cycling through every season over 33 years.

5. The Hundred Years' War between England and France 116.6 years

   Despite the name, it lasted 116 years (1337-1453), punctuated by long truces — and technically England and France stayed at war on paper even longer.

6. A photon's journey from the Sun's core to its surface 170K years

   Energy ricochets through the dense interior for on the order of 100,000 years — then crosses the void to Earth in barely eight minutes.
