Hi, I have been lurking and have to ask a burning question! Mauro Lacy or anyone: in a hypothetical situation... Let's say for instance that the earth was in near alignment with galactic central point and then wobbled about it for a few days (such as it does at the winter solstice). What kind of fluctuations would be expected by your hypothesis?
Thanks for your time. -Cosmo On 9/7/10, Mauro Lacy <ma...@lacy.com.ar> wrote: > Hi, > The results of both papers are addressed, to a certain extent, in > "Power Spectrum Analyses of Nuclear Decay Rates" > http://arxiv.org/abs/1007.0924 > > Mauro > > On 09/06/2010 02:31 PM, Harry Veeder wrote: >> Here are two papers which find no evidence of periodic fluctuations in >> decay >> rates.
