Ok, im currently in school in Queesnland, Australia and I want to become a Professor in the field of Cosmology/Quantum Gravity (theoretical not experimental physics). Now what I want to know is would I have to do my undergraduate/postgraduate studies overseas in the states or Europe to be sucessful in the field. I'm just wondering this because I've never heard of any major research in physics being done in Australia, all of the breakthroughs or famous physicts are from Europe or USA. And if i do have to move overseas, how hard is it as an international student to get accepted and what sort of costs would i be looking at for the degrees. I'd always wanted to eventually move to an overseas university to work because of the respectability gained in top notch universities, but I don't know if coming from a University in Australia would cause me to be seen as not as good as people trained in Universities in the country I want a job in.
