A quick Google says that there are an estimated two trillion galaxies, each with an estimated 100 billion stars on average, with an average of 1 planet per star.
That means there's an estimated 200 trillion billion planets.
Don't you think it's incredibly improbable that our Earth is the only one?
- tsimionescu 5y agoI think that's impossible to estimate, at least for some definitions of "Earth-like".
- Sohcahtoa82 5y agoIt's impossible to estimate a total number, for sure, but I think it's perfectly reasonable to believe that there's at least 1 other Earth-like planet in the universe.
