The simple definition of a meter? Boring. The absurdly precise scientific definition that involves krypton atoms and light traveling through vacuum? Now we're talking! 🔬

This is peak science humor capturing how scientists love to take something straightforward and turn it into the most complicated explanation possible. The original meter definition (a platinum-iridium bar) was replaced in 1983 with this mind-bending definition based on the speed of light.

Fun fact: The definition has actually been updated again! Since 2019, a meter is defined by taking the fixed value of the speed of light (299,792,458 m/s) and the definition of a second. Scientists just can't leave well enough alone!
