The discussion centers on the challenges of pursuing a PhD in physics while remaining in Bolivia, where such programs are unavailable. The original poster (OP) seeks a program that does not require physical presence, citing family obligations. However, participants clarify that reputable PhD programs typically require some residency for coursework, advisor interaction, and research components. They emphasize that while full-time residency may not be necessary, a certain amount of physical presence is essential for completing a PhD. Suggestions include considering future relocation when family circumstances allow, as well as cautioning against programs that promise graduate-level coursework entirely online. The conversation highlights the importance of balancing personal obligations with academic aspirations.
