The problem is that some of the big questions in physics appear very simple if your knowledge of the subject lacks any depth. It is also very difficult for some people to gauge the depth of their knowledge. All of this is exacerbated by endless popular science shows which give people the sense of understanding, without the necessary substance. In short, it is not enough to understand by analogy, you need the math and the science. Most people who aren’t in the field lack that, but are culturally inclined to comment.
