My BSc thesis was on general relativity MY MSc thesis was going to be on modified theories of gravity and cosmology, in hope of pursuing a PhD in this area or similar one day.
I know replies are going to be why would you want to do a PhD in an area you don't want to do master's level research at.
However, modified theories of gravity and cosmology would be my second choice right now, just from brief reading around, I don't think it's going to compare to the excitement of first learning general relativity and I did some reading around for PhD interviews- I got short-listed a fair amount and was told my academia and project description were strong and good enough, but really my lack of enthusiasm let me down-which is the story of my life because I'm a bit shy, anyway, so I just fancy a bit of a break from it, and I was thinking of a topic that involves a bit of pure maths as well as mathematical physics.
I guess pretty much my question is can you get a PhD in an area you didn't do your masters thesis?
Would it significantly lower my chances.
Could it perhaps be the case that I really enjoy my master's thesis and want to pursue a PhD in this instead?
Thanks
