If We Believe in Dark Matter, Why Not Extraterrestrial Life?
- gus_massa 7y agoWe have an accurate model for gravity. It fails in galaxies, so the conclusion is that there is something else and we call it "Dark Matter". An alternative is to change the model of gravity, but the attempts so far have been unsuccessful. We don't have a good model for life. We have only one example and don't understand all the details. The Drake equation is not a model, it's just a multiplication of unknown coefficients. I think that bacteria-like/arquea-like life in other planets outside the star system is very very probable, almost inevitable in viable planets. Prokaryote-like life is more difficult. But nobody is sure. Anyway, the main article is about the claim that the ‘Oumuamua asteroid in a solar sail. The solar sails are the main research field of the interviewee and he trid to hijack the events and claim that the asteroid is a solar sail, but nobody believed him. The asteroid has a tiny deviation in the orbit, that is measurable and nobody has explained yet convincingly. But there is not enough evidence to support not only that there is intelligent life in other star system and also that they send a solar sail here.
