Hi, I was wondering what the scope is these days to do a PhD in theoretical physics, but without delving into string theory? Is the world of theoretical physics still very much dominanated by string theory, or can young physicists go down alternative routes? I seem to remember that some years ago, about 90% of theoretical physics PhDs were all on string theory - is it a similar story today? If so, does anyone find this very restrictive? What if you want to look into different theories of everything? Where can you go? Or do you have to fall in step with string theorists? I would love to get some more information on this. Thanks.
