I need some advice regarding studying abroad for someone planning on going to graduate school in physics. I've always wanted to study abroad for a semester and I've heard nothing but great things about people's experiences. Last semester I got involved with a nuclear physics research group (mostly computational) and the P.I. has basically guaranteed me a spot throughout my undergrad as long as I remain competent. However, if I leave to study abroad for a semester then I'll likely lose my position. Is the study abroad experience worth losing the extra research experience? Does it look better to graduate schools that you've stuck with one research group the entire time? I'm not sure how much potential there is for me to publish through this group. Any input and personal experiences would be appreciated.
