Velocity Addition Calculator
Calculate relative velocities in special relativity
📖 Velocity Addition
The Velocity Addition 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.

💡 Tips & Information
- Formula: v = (v₁ + v₂) / (1 + v₁v₂/c²)
- Velocities don't simply add in relativity
- Result is always less than c
- Used in particle physics
- Explains why nothing exceeds light speed
