"While there is no obvious visible companion star to our Sun, there could be a dark binary, such as a brown dwarf or possibly a relatively small black hole, either of which might be very difficult to detect, without accurate and lengthy analysis."
By reading further and above all by listening to the interview with Cruttenden, the author of the book in SY's yugas, I understood what follows:
- If the sun's dual is a brown dwarf or a black hole, the distance of such dual should be pretty small,
maybe too small for the dual not to be noticed (enphasys is my remark).
-The sun's dual is believed by Cruttenden to be Sirius, and this would necessitate a revisitation of the velocity of the solar system, which some recent literature proposed. A model based on such revision would be coherent with a binary system with the sun and Sirius.
