I'm an undergrad at a large research university and I've been working in a high energy physics group for about two years now. Recently, a postdoc (my main advisor in the group) and I got into a more general discussion about high energy physics as a whole. He is very concerned that the funding for high energy physics has been shrinking in recent years and that many of the accelerators are turning away from high energy research. He sited a recent scare that happened where either Jefferson Lab or Brookhaven would be shut down (fortunately never happened) and how SLAC is moving towards condensed matter research. I remember him saying something like that I should think about if I want to "take a leap of faith" and go to grad school for HEP as he seems concerned that the field is shrinking. My time with the group so far has gone really well and I'm thinking that I probably do want to go to grad school for HEP. However, I don't want to submerge myself in something like this if there is not going to be opportunities later on to continue in the field.
