Hello, I'm Simplexity22. I wanted to let you know that one or more of your recent contributions to Giant-impact hypothesis have been undone because they did not appear constructive. If you would like to experiment, please use the sandbox. If you think a mistake was made, or if you have any questions, you can leave me a message on my talk page. Thanks.
