Answer
**Astrophysics was not a topic of interest for Maurice Merleau-Ponty, a French philosopher.** Merleau-Ponty's philosophical inquiries primarily centered on phenomenology, existentialism, and the relationship between consciousness and the physical world. His notable works include "Phenomenology of Perception" and "The Visible and the Invisible," focusing on themes such as embodied cognition, intersubjectivity, and the role of the body in human experience.
