Extrapolations from an article “The Fermi Paradox” on WaitbutWhy.com
- For every grain of sand on Earth there are 10,000 stars in the universe. Estimated 5% of which would be sun-like (500 billion billion).
- 22% of all Sunlike Stars in the universe have watery earth like planets orbiting them.
- There would be 100 billion billion earth like planets in the cosmos. One billion in our galaxy alone.
- This means that for every grain of sand on earth there are 100 earth-like planets in the universe.
- Now let’s assume just 1% of those inhabited planets have life that’s evolved to an intelligent civilization. Like what we see on earth.
- That means for every grain of sand on Earth there is a planet in the universe with intelligent life equivalent to ours.*
- When we apply the same logic to the Milky Way, we have 100,000 intelligent civilizations seeded among the billion earth-like planets. Right in our Galaxy, out there waiting for us.
