This is a very good podcast on binary star systems, the host being a researcher of astronomy of the Illinois university.
The hunt for binary systems has been ongoing of decades. In 2009 there were already many many researchers spending their time observing the universe and ascertaining with the techniques explained if the observed stars are single, or visual binaries, or spectroscopic binaries and so on.
It is nearly impossible that they did not recognize a close-by twin of the sun. Maybe impossible is the right word. They apply sophisticated techniques like doppler spectroscopy, where they detect the stars moving out and in, closer and further, periodically, giving evidence of a revolution motion.
If SIrius were a twin star of the sun, we would have tons of evidence by now.
I strongly suggest you listen to this awesome episode, stellar systems with up to septuple star revolving among themselves have been reported
http://www.astronomycast.com/2009/09/ep-152-binary-stars/I’d much rather take up investigation and research at Yogananda’s writings and the laboratory he recommends in our own meditation practices. The evidence there is overwhelming. I have found on this subject scientists are mostly payed to maintain their own paradigmatic prejudices. Never met any who could get beyond their own one dimensional linear prejudices. My insights are not appreciated and I’ve been told to go else where at their academic edifices where such spiritual experiences and insights are simply brushed off as ‘superstitious behavior’. We already know that we have nearby stars in comparative space distances. What we are not entertaining from a ‘scientific’ point of view, is the possibility of their being our binary. Because it has already been established that the explanation for procession is the earths wobble. As a result the notion that precession as occurring as a result of other factors is simply denied. This is a typical response in religious and scientific communities where it is important to maintain the status quo to keep certain ideas holding up the framework of ideological prejudices.
