An error in the E<0 case[edit]
It seems there is an error in the solution $R(r,t)$ to the evolution equation in the case $E<0$. For the radius, the current text states R = (M/2E) [1-cos (eta)]. The right hand side is negative (E<0 !!) while the radius should be positive; I'm reluctant to correct it myself because errors may have propagated farther than just that and this correction alone may not be comprehensive.
where the E propto M^{2/3} error came from...[edit]
For people who saw this page earlier (or edited without checking), the E propto M^{2/3} error that sat on this page was introduced by the original author: [1] in his/her second edit. This editor: Special:Contributions/Ccwth clearly made a lot of useful and well-intended edits on this general topic, for just two days, and then disappeared from wikipedia. For three and a half years, nobody noticed the error... Boud (talk) 13:43, 10 March 2011 (UTC)
