Please remember to sign your name on talk pages by using four tildes, like this: (~~~~). This will automatically produce your username and the date. Also, please do your best to always fill in the edit summary field, as this will help other users to know what you changed and why you changed it. Below are some (rather boring, but) useful links to help you learn your way around the encyclopedia as well as to help you become a successful editor.
I hope you will like editing here, and I hope you enjoy being a Wikipedian!
Welcome to Wikipedia. Although everyone is welcome to make constructive contributions to Wikipedia, at least one of your recent edits, such as the one you made to Hubble's law, did not appear to be constructive and has been removed. Please use the sandbox for any test edits you would like to make, and read the welcome page to learn more about contributing constructively to this encyclopedia. Thank you.
