Given the relatively high statistical likelihood that we are part of a binary system, do you know if mainstream scientists have begun to explore this premise, gravitational aberrations etc due to a sister star?
The Binary Star model is not mainstream.
The Indian connection raises a number of questions.
How did the Vedics determine a 24 000 year cycle?
How and when did the concept of the possibility of our living in a binary system develop? Until Copernicus, heliocentricity was not believed.
Sri Yukteswar was given the knowledge from Babaji. Babaji was the guru of Lahiri Mahasaya who was Sri Yukteswar's guru. You will know this from Yogananda's autobiography. Lahiri Mahasaya met Babaji in a cave which was the beginning of his spiritual journey, but no mention of precession, binary stars etc was mentioned.
Babaji only met Sri Yukteswar once. And this was to give him the astronomical knowledge thus bypassing Lahiri Mahasaya. So, it doesn't appear that many were aware of the concept.
I couldn't imagine mainstream astronomers being guided by this set of events.
I still remember my SRF lessons arriving in the mail each month in an envelope made from some shiny paper long before I read the book.
