Online PhD programs in Physics are generally viewed with skepticism due to the nature of doctoral studies, which typically require extensive collaboration with supervisors and immersion in a scientific environment. Most universities do not offer part-time PhD options, as being a doctoral student is usually a full-time commitment. Exceptions exist for industrial PhD students in technology fields and certain medical disciplines, where candidates may balance their studies with employment. However, even in these cases, part-time PhD programs can extend the duration of study to around ten years.
