I recently submitted a manuscript to Physical Review Letters, the editor sent it out to two referees. One of the referees sent his comment back on the second day. Do you think-based on your experience-this bodes well or the paper received a disastrous comment from the referee?? I know this question is kind of ridiculous for a lot of the people here, I mean, what can I do. But I am a little worried.. Thank you for your comments!
