@j @coolboymew There's nothing wrong with asking those questions, those are both good questions. If you don't know anything about physics/penguins, they are exactly the right kinds of questions to ask. Waiting until adulthood to learn about penguins is definitely forgiveable. And physics is a big topic, and the difference between not knowing about the basics like that and not knowing how say synchotron radiation works (as I don't) is mostly a matter of degree.
