I agree that the post you were replying to makes no sense as a reply to your previous comment. I'm guessing that that author meant to reply to the poster saying that sonic booms were mythical, and did not mean to reply to your post.

Your comment, "wut", although it would be totally appropriate in a conversation between two people, is just more noise when read by the thousands of people who read through the comments. When people make irrelevant short replies, it's usually best to ignore them and let other other people downvote them.
