Career opportunities in astrophysics, electrodynamics, and quantum physics open up to you when you learn relativity. There are also physics-based jobs in a number of other fields, such as astronomy and astrobiology where you look to space for answers. Clean energy jobs influenced by relativity are in the solar energy field. If you enjoy teaching, there are teaching jobs at the high school and college level for physicists and professors. You can also pursue engineering opportunities as a laser engineer or design engineer when you study relativity.
