Hi everyone, I want to do an MS in Astrophysics. The thing is, I completed my BE in Mechanical Engineering in 2009 and I had been working as an Assistant Engineer at Taj Hotels (The hospitality arm of the Tata Group). I was in charge of installation and maintenance of DGs, boilers, chiller...

Hello everybody, my name is Paolo! I am now attending my 4th year (out of 5) of high school in Italy and I would like to study astrophysics at university. Space has interested me since I was at primary school, so I'm very determined about my decision. Yet I have some doubts. First of all...

I'm currently taking an astrophysics course, and need to do a project on some sort of on-going astrophysics research. Over the last year, I've been reading a few papers here and there in QG (specifically LQG), and was wondering if there was any on-going research relating quantum gravity in...

I am soon to apply for university and I am not quite sure what I want to study. Theoretical physics and astrophysics/astronomy/cosmology all seem like very interesting fields of physics to me. How do I go about when I choose my career path? Which one of the fields has been more prospering than...

I'm interested in taking some astrophysics classes in Univeristy, and I am just wondering if I have to take Chemistry in high school to be able to take the classes? Or does it depend on the University you are going to?

I'm thinking of doing an astrophysics degree and was wondering what career choices would be available to me after this with just the degree. I would hope to do a masters and so on but that may not work out. I know i could go into research with the college or university but other then that I am...

Hi all, earlier this year I asked about astronomy vs physics, and the general consensus was that, at least in the academic world, astronomy is thought of as fringe in the sense that you won't get hired to a physics post or be able to do physics research, but a physicist could do astronomy...

Hello, I am reading Virial theorem from Wikipedia. It states in astrophysics, virial relations are: 3/5 GM/R=3/2... I want to know how this 3/5 and 3/2 value comes from? If somebody can explain the step by step deduction of the Virial theorem in Astrophysics... Thanks, --...

Hello everyone, this is my first time posting on the site. I'm 18, live in California, still in high school, and I'm going to graduate come November. I'm going to either a state university, UC Irvine, or a community college and majoring in Astrophysics. The only math I know is algebra and...

I live in a home where we don't make very much money, but I would really like to go to school for Astrophysics. As of right now I do not know a lot as far as the mathematical processes go, so depending on where I were to get a scholarship or grant it might be rather difficult. What other ways...

Hey, I need some advice. I am thinking about grad school for astrophysics and trying to decide what I should do. The question I am posing is that given the low availability of PhD astro job would it be better just to become an engineer (electrical) and do astronomy/astrophysics on my own if...

I'm very fascinated on both things. I want to study Black Holes, Dark Matter and Dark Energy. Stuff like that in the big world of Astrophysics, but I'm also very attracted to particle physics with the ways forces works on atomic scale, and how elementary particles work. I really have a hard time...

In a nutshell, I'm a 26 y/o currently active duty military member with 8 years in (as a Aviation Ordnance Aircraft Mechanic), and plan on getting out honorably late next year. I've always been interested in the universe (black holes especially) [SIZE="1"](and the fact we are literally a way...

I have heard much about how careers in aerospace engineering and astrophysics can be hard to find, one has to move around a lot, and the salary is not great. As far as money goes I don't care too much, but I'd like to make at least 75k a year, but I don't want to have to move around more than 2...
