Hello, I'm Materialscientist. I wanted to let you know that I reverted one of your recent contributions—specifically this edit to Mod Sun—because it did not appear constructive. If you would like to experiment, please use the sandbox. If you have any questions, you can ask for assistance at the Teahouse or the Help desk. Thanks.

Please do not remove content or templates from pages on Wikipedia, as you did to Mod Sun, without giving a valid reason for the removal in the edit summary. Your content removal does not appear to be constructive and has been reverted. If you only meant to make a test edit, please use the sandbox for that. Thank you.

Hello, I'm Adakiko. I noticed that in this edit to Laser communication in space, you removed content without adequately explaining why. In the future, it would be helpful to others if you described your changes to Wikipedia with an edit summary. If this was a mistake, don't worry, the removed content has been restored. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thank you. Adakiko (talk) 08:02, 20 February 2024 (UTC)
