"In My Day We Had 9 Planets" lies the nostalgia and lighthearted commentary on how scientific knowledge evolves over time. It refers to the reclassification of Pluto from a planet to a "dwarf planet" in 2006 by the International Astronomical Union (IAU). Before then, people grew up learning that there were nine planets in our solar system, with Pluto as the ninth.
The phrase often pokes fun at the generational differences in what was considered "fact" during someone's lifetime, implying that the speaker is lamenting the "loss" of Pluto as a planet while acknowledging that the change doesn't really affect their daily life. It's a playful nod to how science challenges and updates our understanding of the universe, and it sparks a chuckle because of the harmless yet exaggerated "outrage" over Pluto's demotion.
Do you miss Pluto as the ninth planet, or do you think the update makes sense scientifically?
