* Cosmologist: This term usually refers to a scientist who studies the universe's origins and evolution, often using empirical evidence and scientific models. However, a philosopher could also call themselves a cosmologist if their focus is on the philosophical implications of cosmological theories.
* Metaphysician: This term describes someone who studies the fundamental nature of reality, including questions about existence, time, space, and causality. Such a person might explore the philosophical implications of the origin of the universe and its nature.
* Philosopher of Science: This is a broad category, but a philosopher of science might focus on the philosophical implications of scientific theories, including those about the universe's origin and nature.
* Natural Philosopher: This term is more historical, referring to scholars who explored the natural world using observation and reason before the development of modern science. While not common today, it could be used to describe a person who engages in philosophical inquiry about the universe in a broader, non-scientific sense.
Ultimately, the most accurate term would depend on the specific approach and focus of the individual's philosophical work.
