A former astronomy guide at the Sydney Observatory has shared an anecdote about an eight-year-old's question that reshaped their approach to explaining black holes. The guide, who led tour groups of approximately 20 people, often used a planetarium to show celestial objects like the Hubble Ultra Deep Field image.
During one tour, the discussion turned to black holes and the phenomenon of spaghettification. This occurs when an object gets too close to a black hole, experiencing a stronger gravitational pull at one end than the other, causing it to stretch like spaghetti.
After the guide explained spaghettification, a young girl asked, "So would the blood be the sauce?" This question led the guide to realise the need to explain the concept using stars falling towards a black hole, rather than humans, to avoid unintended interpretations.
