the situation of our planet, all the things i said above (in particular non-gravitational locked, magnetic field, water & continents) is a 1/N event.
I feel like N is very large. When you factor out all the stars of the 100 billion in the milky way, I think you get something unlikely, let alone on a planet in the habitable zone.
also, something on the other side of the milky way (100,000 light years), is also far away, so its not like we have the entire milky way to choose from.
- wellboy 9y agoUsing average values in the drake equation, there have been have been 18 million broadcastable civilizations in the milky way. If we take an average lifespan of 1,000 years and say those cilizations have formed over the last 5 billion years (where planets mostly cooled down throghout the universe) then there are currently only 4-5 broadcastable civilizations in the milky way. Is that correct?
