  1. A single wingbeat of a hovering hummingbird 12.6 ms

    Up to 80 wingbeats per second lets hummingbirds hover, fly backwards, and even fly upside down — no other bird can do all three.

  2. Sunlight travelling from the Sun's surface to Earth 8.3 min

    If the Sun vanished right now, we'd keep seeing it — and orbiting it — for another 8 minutes and 20 seconds before noticing anything.

  3. The record-winning Vendée Globe solo sail around the world 64.8 days

    Charlie Dalin's 2025 run was nonstop, alone, and unassisted — skippers sleep in 20-minute bursts for the entire circumnavigation.

  4. 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.

  5. The construction of the Sagrada Família in Barcelona (so far) 143.9 years

    Begun in 1882 and still unfinished, it only received an official building permit in 2019 — Gaudí said 'my client is not in a hurry'.

  6. The time since Vesuvius buried Pompeii 1.9K years

    The AD 79 ash preserved loaves of bread still sitting in ovens — one carbonized loaf even bears its baker's stamp.
