Ever wonder why energy, the cosmos, or space and time exist?
Well, you are not alone. Through the minds of theoretical physicists, exploring the origin sided with evolution of mathematics, physics, and the human perception of what we call existance, they see it as their job to simply, "discover." (I will explore this later)
Theoretical physics is one of the many branches that employ mathematics and physics to help rationalize our perception of life.
Ordinarily, while researching, theoretical physicists will teach at universities. After obtaining their Ph.D., they may pursue fellowship to further explore their specialization.
Depending upon the specialization, a supplemental salary of 70k alongside of a 90k salary of teaching at a notable university.
Requirements to become a theoretical physicist includes a vast amounts of classes covering all derivatives of physics and mathematical topics.
