While it's good to see an enthusiastic contributor, please take a look at the Cite your sources and No original research guidelines when deciding what additions to make to articles. In particular, your additions to black hole and white hole made claims that weren't supported by any of the reference material cited. Specifically: Your additions to black hole and wormhole also restated things that were already covered in the article.
 * There are several valid ways of defining a time coordinate within a black hole.
 * Under most coordinate systems, a black hole does not appear to have infinite volume.
 * White holes aren't produced by the collapse of stars. The reasons for this are described in the article itself.
 * White holes don't necessarily emit matter (they're a vacuum solution).
 * While it _seems_ like it should be possible to collapse a white hole, any assertation to that effect should be backed up by a link to a physics journal paper on the subject (that's why I didn't add anything about it, despite it being mentioned on the talk page).

I'm not trying to scare you off from editing Wikipedia - it's great to see new editors who are trying their best to make valuable contributions - but please check the policy links I gave above, and take the time to carefully read through the existing article text before changing or adding to it. Also, if you have questions or suggestions about an article, you can always post them to the talk page if you're not sure if altering the article itself is a good idea.

Happy editing! --Christopher Thomas 02:53, 28 March 2006 (UTC)
