Mainstream Science Finally Recognizes Need for a Companion.
Bad News. They Still Don’t Realize it’s Visible in the Hood. Stay Tuned.

A new theory published today in the Astrophysical Journal Letters by scientists from Harvard University suggests that the sun may once have had a binary companion of similar mass. If confirmed, the presence of an early stellar companion increases the likelihood that the Oort cloud was formed as observed and that Planet Nine was captured rather than formed within the solar system
Dr. Avi Loeb, Frank B. Baird Jr. Professor of Science at Harvard, and Amir Siraj, a Harvard undergraduate student, have postulated that the existence of a long-lost stellar binary companion in the sun’s birth cluster—the collection of stars that formed together with the sun from the same dense cloud of molecular gas—could explain the formation of the Oort cloud as we observe it today.
Popular theory associates the formation of the Oort cloud with debris leftover from the formation of the solar system and its neighbors, where objects were scattered by the planets to great distances and some were exchanged amongst stars. But a binary model could be the missing piece in the puzzle, and according to Siraj, shouldn’t come as a surprise to scientists. “Previous models have had difficulty producing the expected ratio between scattered disk objects and outer Oort cloud objects. The binary capture model offers significant improvement and refinement, which is seemingly obvious in retrospect: most sun-like stars are born with binary companions.”
