I love the cosmos. I've pretty much seen every single documentary related to the cosmos, space travel, astrophysics or science in general. I'm also extremely interested in new technologies and scientific developments.
I can enjoy a serious (or wacky) discussion about pretty much any subject for as long as the other person is up for it. I love the feeling of having a long and adventurous discussion with someone, because you get to know their personality based on how they react to different subjects or how they view different things.
I like a person who is kind, relaxed, logical and who has a passion for something. Someone with an appreciation for health, science and technology, honesty and openness.
I usually won't like a person who is religious or believes strongly in unsubstantiated claims.
