Dr Dino…what a joker. Someone (a supporter, in fact) asked him on a radio phone in how it was the sun could burn, because combustion needs oxygen and there’s no oxygen in space. He couldn’t answer!
Highly qualified scientist there, not having heard of nuclear fusion.
Scientists are highly qualified in their areas of study. outside those areas, a scientists knowledge drops significantly. It all depends on their level of interest and participation in areas outside their realm. Even where I work, different scientists have different ideas about each other's specialties and are not necessarily aware of what thoseother areas entail.
