By duration · Order from shortest to longest.

  1. An average human's reaction to a starting gun 252 ms

    Athletics rules treat any sprint start faster than 100 milliseconds as a false start — it's considered humanly impossible to react that quickly.

  2. The men's 100 m freestyle world record swim 46.4 sec

    Pan Zhanle's 46.40 at Paris 2024 stunned the field — he won by over a second, an eternity in a sprint event decided by fingernails.

  3. The Epsom Derby, Britain's most famous horse race 2.5 min

    Workforce's 2010 record run covered the mile and a half at over 56 km/h — and the race has been run every year since 1780, even through both World Wars.

  4. A football (soccer) match, regulation time 90 min

    The ball is typically in play for barely 55 of those minutes — which is why competitions now add increasingly enormous stoppage time.

  5. One full rotation of Earth on its axis 23.9 h

    A true rotation takes 23 hours 56 minutes — the extra 4 minutes of our day come from Earth also moving along its orbit and needing to catch up to the Sun.

  6. The Cold War 43.9 years

    Historians call it 'the long peace' — the superpowers never fought each other directly, but proxy wars touched nearly every continent.
