Talk:Van Stockum dust

Licenses of figures

Hmm... I didn't think very much about that, but of course I am not licensing software but rather making these images, which I drew using Maple (not freeware, but they own the software, not the images users make with it!) freely usable by anyone. If any admin should happen to read these lines, it might be good to help me fix the licenses as stated in the image files.---CH (talk) 07:41, 11 September 2005 (UTC)

Students beware

I created the original version of this article and had been monitoring it for bad edits, but I am leaving the WP and am now abandoning this article to its fate.

Just wanted to provide notice that I am only responsible (in part) for the last version I edited; see User:Hillman/Archive. I emphatically do not vouch for anything you might see in more recent versions, although I hope for the best.

Good luck in your search for information, regardless!---CH 19:56, 1 July 2006 (UTC)

Clarity Needed

As an earnest reader who has not advanced to the level of mathematics and physics assumed by this article, I found it difficult to determine exactly what was so special about Von Stockum dust and what the model is supposed illustrate. The math is great for physics Ph.D.s, I'm sure, but it needs to be supplemented by some more accessible plain-english explication.

Note: You don't have to get all Sesame Street on me; just provide some context and an overview that I can understand without having taken graduate-level mathematics. —Preceding unsigned comment added by 98.210.32.163 (talk) 18:51, 7 November 2009 (UTC)

Yes, clarity is required indeed. How fast would it have to rotate for notable effects to occur, how large would the dust have to be, and wouldn't every dust particle be spread arbitrarily upon spacetime due to the effect, so that once you put any matter inside this hypothetical time machine, it only works as a more sophisticated vaporizer? --2003:71:4E6A:C970:7DC8:9C45:7CAF:D75B (talk) 04:49, 20 January 2016 (UTC)
