>>14168456physics is a dead field, nobody cares about the big questions anymore, everybody is after funding, deceiving funders even. also it's very dry as unlike 1920s big philosophical questions considered harmful and pseudoscience.
another thing is that if you don't have a phd in specific sub field, nobody wants you to talk about the field, einstein would continue his career as patent clerk if he lived in our times.
so my advice is you to get into machine learning and have some real money, if you have monetary freedom perhaps you can continue scientific journey if your brain is not mutilated by the scientific community yet.
