>>10815269I confirm there's some truth to this.
There are three options for careers in physics:
1.) Stay in academia and teach and do research in physics (be employed by government or college)
2.) To become employed by a private company to do reacher for them.
3.) Become self employed
The fist two REQUIRE at least PhD with publications. So you if you're thinking of finding the job the conventional way, and if you choose a physics major, you are also need to devote another 7+ years to getting your PhD.
for option number 3, the less conventional way, a PhD is not required, but is also just as risky, because nobody is going to provide you with the answers.
