Calculate length contraction in special relativity
📖 Length Contraction
The Length Contraction estimates the number of active, communicative extraterrestrial civilizations in the Milky Way galaxy. It multiplies several factors: star formation rate, fraction with planets, habitable planets per star, etc.
