¿Estamos solos en el universo?

Yo creo, sinceramente, que las posibilidades (de estar solos) son muy pequeñas...pero en todo caso lo mejor es escuchar a Jill Tarter, en esta muy buena entrevista, en la que además formula una de las mejores definiciones (y alabanzas) de la carrera científica que he leído:

Tippett: You’ve spoken about your love of, really, the creativity of the scientific enterprise and that you see, in our time, science providing raw material for all kinds of new forms of expression, also, in the humanities, and that you — as a scientist, you get to never stop asking, “Why?” [laughs]

Tarter: Yes. You never have to grow up. There are always — you can keep asking questions, and then you can try and find answers, which will probably lead to a lot more questions. Science is all about finding answers to questions that no one else has yet found an answer to. It’s about puzzle-solving. It’s about mystery. It’s about challenges. It’s fun. It is so rewarding to understand something for the first time that no one else has been able yet to understand and to pass that information along and then go on to the next question that is inspired by what you’ve just understood. So I think we need to tell our students that science is a fantastic way of spending a career and having fun and being challenged and never being bored.
