- There was a time when I thought a great deal about the axolotls. I went to see them in the aquarium at tbe Jardin des Plantes and stayed for hours watching them, observing their immobility, their faint movements. Now I am an axolotl.
- Light-year (Wikipedia)
A light-year, alternatively spelled light year (ly), is a unit of length used to express astronomical distances and is equal to exactly 9,460,730,472,580.8 km (Scientific notation: 9.4607304725808 × 1012 km), which is approximately 5.88 trillion mi. As defined by the International Astronomical Union (IAU), a light-year is the distance that light travels in a vacuum in one Julian year (365.25 days). Because it includes the word “year”, the term is sometimes misinterpreted as a unit of time.
