People! Must I be really be the one to remind you that we're dealing with Chinese fortune cookies here?!
The operative word being 'Chinese'!
Now then, who is the most famous writer in Chinese literature?
Chairman Mao?

"New evidence that all stars are born in pairs"
As per the article:
'Astronomers have even searched for a companion to our sun, a star dubbed Nemesis because it was supposed to have kicked an asteroid into Earth's orbit that collided with our planet and exterminated the dinosaurs. It has never been found.
The new assertion is based on a radio survey of a giant molecular cloud filled with recently formed stars in the constellation Perseus, and a mathematical model that can explain the Perseus observations only if all sunlike stars are born with a companion.
"We are saying, yes, there probably was a Nemesis, a long time ago," said co-author Steven Stahler, a UC Berkeley research astronomer.
"We ran a series of statistical models to see if we could account for the relative populations of young single stars and binaries of all separations in the Perseus molecular cloud, and the only model that could reproduce the data was one in which all stars form initially as wide binaries. These systems then either shrink or break apart within a million years."'
Here's the link to the article: http://news.berkeley.edu/2017/06/13/new-evidence-that-all-stars-are-born-in-pairs/
And, for hardcore astronomy students, here's the link to the original arXiv.org paper: https://arxiv.org/abs/1705.00049
By shrinking, I assume they mean one star/big mass ate the other?
I would think that it is a possibility, but that particular scenario isn't mentioned in the arXiv.org paper.
As I understand it, the authors believe that the stars in the particular cluster they studied either circle in closer together and remain binary systems, or they separate entirely.
Barring another big mass passing by, I am unsure how they would separate.
Have you talked about this article/paper with any of the professional astronomers you work with? If so, I would be interested in hearing their opinion(s).
I'm not there anymore. I left at the beginning of the year. I'm doing something entirely different right now, and I don't worry much about the stars. Instead I worry about potable water, sewers, and urban failure modes.
