Robin, Yes this Rydberg calculation is close, but probably not close enough. Red shift could change that assessment and make it exact.
As you know, Mills addressed this issue years ago (that dark matter is composed of hydrinos) and he concocted a formula that unfortunately provides a value which is also close, but not even as exact as this one. I do not have that reference handy but it is in the archives. Mills should have waited to see the exact observed value - as now he looks a bit foolish. 3.55 keV to 3.56 keV is the dark matter signal which is seen from satellites in earth orbit and is verified by dozens of cosmologists and Universities nowadays. Any theory that explains dark matter should be able to account for this exact value. Since 95% of observable matter is hydrogen, it is a good bet that dark matter is hydrogen in another form - but of course, it could be something else entirely and there are a few candidates but none are as convincing as dense hydrogen. -----Original Message----- From: mix...@bigpond.com In reply to Jones Beene's message: Hi, For Mills, the difference between any two adjacent states is (2p-1)*13.6 eV where p is the smaller of the two numbers. Thus the difference between 136 & 137 would be: ((2*136)-1)*13.6 eV = 3686 eV. Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/project.html
