Welcome!

Hello, Tsingpedia423, and welcome to Wikipedia! Thank you for your contributions. I hope you like the place and decide to stay. Unfortunately, one or more of your edits have not conformed to Wikipedia's verifiability policy, and may be removed if they have not yet been. Wikipedia articles should refer only to facts and interpretations that have been stated in print or on reputable websites or other forms of media. Always remember to provide a reliable source for quotations and for any material that is likely to be challenged, or it may be removed. Wikipedia also has a related policy against including original research in articles. As well, all new biographies of living people must contain at least one reliable source.

If you are stuck and looking for help, please see the guide for citing sources or come to the new contributors' help page, where experienced Wikipedians can answer any queries you have! Here are a few other good links for newcomers:
 * The five pillars of Wikipedia
 * How to edit a page
 * Help pages
 * Tutorial
 * How to write a great article
 * Simplified Manual of Style

I hope you enjoy editing here and being a Wikipedian! Please sign your name on talk pages using four tildes ( ~ ); this will automatically produce your name and the date. If you have any questions, check out Where to ask a question, ask me on my talk page, or you can type   on your user page and someone will show up shortly to answer your questions. Again, welcome!

Spherical earth
Besides not having a source, your edit is original research - see WP:NOR. I'll also point out that we can and do observe the earth 24/7 with satellites. 08:51, 28 June 2013 (UTC) — Preceding unsigned comment added by Dougweller (talk • contribs)
