Drake equation estimates number of communicative civilizations in Milky Way by multiplying star formation rate with life/civilization probabilities.
分步指南
- 1Input factors: star formation rate, planet fraction, life probability, civilization fraction, etc.
- 2Multiply all factors
- 3Result shows estimated number of civilizations
例题解析
输入
Conservative estimates
结果
N ≈ 1-10 civilizations in galaxy
Highly speculative
常见错误注意事项
- ✕Over-interpreting uncertain parameters
- ✕Neglecting time factors (civilizations evolve)
