1. One heartbeat of a hummingbird in flight 48 ms

2. 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.

3. Yuri Gagarin's entire Vostok 1 spaceflight 108 min

   The first human spaceflight was a single orbit — and Gagarin ejected and parachuted down separately from his capsule, landing in a potato field.

4. An evening at Wagner's opera 'Götterdämmerung', intervals included 5.5 h

5. A horse's pregnancy 340 days

   Foals can stand within an hour of birth and gallop within a day — a survival feature for a prey animal born on open grassland.
