Most people assume that the dinosaurs were killed by a giant meteor impact 75 million years ago. However, scientists have recently found evidence that the catastrophe might have been caused by a much more sinister and destructive force. According to Astronomers at UC Berkley, the terrible lizards might have been wiped out by the Sun’s evil twin.
Called the “Nemesis,” this solar doppelganger is being hypothesized to come back ever 27 million years to cause chaos throughout the Solar System. This is based on the premise that every star is born with a twin, though, not necessarily identical in every way. According to the press release on the university’s website, the one responsible for the extinction of the dinosaurs may have been caused by such a twin.
One of the astronomers behind the study is Steven Stahler and according to him, their calculations suggest practically every single star was born beside another.
“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,” Stahler said.
Now, there are a few things worth noting in these findings. One is the fact that Nemesis is most likely long gone, at this point, but the scientists can’t be absolutely sure. More to the point, the star would have been seven times farther from the Sun than Neptune is now, so its effects would have been minimal.
In any case, this development has considerable implications in Astronomy, particularly with regards to the study of galaxy formation. Such changes could even pave the way for a better appreciation of the origins of the universe, Futurism reports, as well as how stars evolved.
