I have been on physics stack exchange for about four years. Some of my answers I am proud of some of them not so much. There is one particular answer where I did my best at the time but I lacked the knowledge to understand what OP was asking. Some people however liked the answer and nobody else replied. I'd like to write a new answer. Should I delete the old one? Should I edit it?
In the future I definitely shouldn't answer something I don't understand. I remember wanting to ask in a comment but not having enough rep at the time.
