A 'cosmologist' is a scientist who focuses his/her studies on the structure and history of the entire universe — how it formed, how it's changed, and what exists within it.
As per Academicinvest.com, those who become cosmologists are typically individuals with a natural interest in celestial bodies, and have a deep fascination for the mysteries and theories concerning the origins of the universe.
Education Needed to Become a Cosmologist
Earning a bachelor’s degree in physics, astronomy, astrophysics, mathematics, or engineering with a focus in a relevant area such as aerospace engineering is typically the minimum requirement to get an entry-level job in cosmology, such as Research Assistant.
The coursework offered by the aforementioned degree programs will help you develop a core set of skills in the laws of physics and provide you with a highly applicable set of skills in mathematics, both of which will be necessary for a career as a cosmologist.
If you want to become a cosmologist that completes your own research projects, directs others in applied research, or teach at the college or university level, you will likely need a master’s or doctoral degree in physics, mathematics, astronomy, astrophysics, or a closely related field such as aerospace engineering. Many students will also complete post-doctorate work in an area of cosmology in which they seek to specialize.
Being a scientist is hard. Being a great scientist is even harder, and rare. What does it take to be a great scientist? Check out some key qualities at Lab.hirschey.org.
