I am just curious about why it is the case. It seems to me that it is even true when compared with Cosmology, which studies similar things. I feel that the people just want to look at stars, and I have ever met people that know what Astronomy is but not Physics. This give me an impression that Astronomy is more like an amateur field. I know it is not, and the real research often involves huge amount of data analysis.
Anyone can give explanation to me?
