That's a good point. I'll switch it to something else.

I'm not really sure if the astronomer question is precise enough. I'm certain Einstein did have an interest in astronomy, and relativity is applied to a lot of astrophysical situations, but I think Einstein is known for relativity and other theories (quantum etc) before astronomy. Same could be said for Hawking, who was definitely a theoretical physicist. I wouldn't say you're wrong, I just think its too imprecise of a question. The rest was good though. The last question is funny too. The idea that maybe it was all of them crossed my mind but I thought it was stupid. Well played!
