The Sun may have had an ‘evil twin’ that wiped out the dinosaurs

While many believe that an ill-placed meteor wiped out the dinosaurs, new research shows that may not be the full story behind.

It may be the sun-or at least the sun’s brother.

According to a new research paper from a theoretical physicist at the University of California and the University of Harvard, the astronomer, the most stars are born with a brother, a sister, or a “brother” to our sun is no exception to the rule.

“Under the assumption that both stars remain embedded following binary fraction, we find a total star formation rate of 168 Myr^-1,” the synopsis of the paper reads. “You can also use a star can be ejected from the dense core by a binary fraction.”


It is likely that the sun’s twin could be significantly far from his brother, and perhaps of 46.5 billion miles or 17 times the distance between the sun and Neptune.

The research ran a series of tests to determine the probability of the existence of the second star, and the emphasis that it is possible that the number of stars that could be “the double of what is currently believed.”

The brother of the sun, called Nemesis, actually had a hand in the direction of the asteroid to the Earth, which led to the mass extinction 65 million years ago.

In the 1980s, two University of Chicago paleontologists theory that the mass extinction was caused by an unknown source from the space, but find it turned out to be fruitless.

Although the paper suggests the Sun had a brother, sister, there is no concrete proof of. Co-author Steve Stahler, a research astronomer at UC Berkely did note, however, that there “probably was a Nemesis, a long time ago.”
