By duration · Order from shortest to longest.

  1. A lightning flash from start to finish 198 ms

    What looks like one bolt is usually several return strokes in a row, heating the air to around 30,000°C — five times hotter than the Sun's surface.

  2. The Titanic's sinking, from iceberg to going under 2.7 h

    The ship's band famously kept playing on deck for most of it — and the iceberg itself had likely calved from a Greenland glacier years earlier.

  3. The Isner-Mahut match, the longest in tennis history 11.1 h

    The 2010 Wimbledon first-rounder stretched over three days with a 70-68 final set — the scoreboard wasn't programmed to go that high and broke.

  4. The first circumnavigation of the globe (Magellan's expedition) 3 years

    Magellan himself never made it — he was killed in the Philippines. Just 18 of the original ~270 crew limped home aboard one remaining ship.

  5. A frilled shark's pregnancy 3.5 years

    At an estimated three and a half years, it's the longest known gestation of any vertebrate — embryos grow just over a centimetre a month.

  6. Voyager 1's journey from launch to interstellar space 35 years

    It carries a golden record with greetings in 55 languages and Chuck Berry — and it still phones home daily on a 1970s 8-track-era computer.
