Existence of extra-solar-system planets was an unproven hypothesis until the 90's but of course anyone could take a guess at its probability.

Existence of extra-solar-system planets was an unproven hypothesis until the 90's but of course anyone could take a guess at its probability.
- defrost 9mo agoSure - it was considered a near certainty planets orbited other stars given all that was known about the formation of our solar system. That said, it's still an extremely low probabilty that life from other systems came and visited our particular rock some time in the past million years (and interacted with humans).
- protocolture 9mo agoYes, and the proponents of that hypothesis built tests to prove their hypothesis. Thats good. They never demanded I take it on faith.
