Trivia doesn't sell domains. It doesn't create demand either.
If you get a serious potential buyer - someone who cares about cosmology / astrology - those are the types that usually get disgusted when someone someone confuses what they do / like with astrology.
To them astrology is junk - a foolish preoccupation. What they do is serious.
Equating the two to them is generally an insult.
If your plan is to tell one of these people that they should pay X amount for cosmology.tv because astrology.tv went for 25K euros - well, that's not really a good approach to dealing with someone who is serious about the subject. You're more likely to hurt your case rather than help it.
I have gemology.tv (non-premium); it's got to be worth something, maybe not as much as astrology.tv.
People searching for their horoscope is not much of a business.
