Hello, I am about to attend the University of Hawaii at Hilo as an Astrophysics major. I intend to complete my education through getting my PhD in Applied Physics, but I wanted to know if it was necessary to get a Master's? I would think so because of getting a BA in Astrophysics instead of AP. I would also think it is dependent on the school offering PhDs in AP. The reason why I chose this path is because I want to work on machines and calculations dealing with Astronomy/Space Travel/etc. I figured with a background in Astrophysics, and a PhD in AP, I'd be a strong candidate. Thanks!
