Yeah it's too bad if people don't feel welcome, attending academic seminars outside your field can be so much fun, all the more so if you ask some questions! People look at you funny when you ask e.g. "what is an M-class star?" in an astronomy lecture, but as long as you have a friend who can say "oh, he's just a physicist" they get over it.
