Don’t answer the question in the thread title – we know for a fact that people have some very strange ideas about how things work.
For instance, lightning and thunder. It’s amazing how thunderously stupid people can be about it. Take this afternoon for example. I was hanging out with my GF’s family, in the pool, when a thunder storm was threatening. The prevailing notion was that lightning and thunder were two completely seperate things. It was generally agreed that thunder happens first, then the lightning follows. When you hear thunder, a lightning bolt will soon follow. It was also generally acknowledged that sound travels faster than light.
I spent a good part of the afternoon debating this with them, and I don’t think I convinced a single one of them.
