Exactly what killed the dinosaurs remains a rather odd mystery – in fact, we still know so little about the colossal lizards that once roamed the earth that we are finding out new tidbits of information on an almost daily basis. Bone discoveries and more besides are building a bigger picture as to what life was like millions of years ago – but we are still no closer to finding concrete evidence, or confirmation, as to what may have killed off the dinosaurs for good. Astronomers based at Harvard and Berkeley, however, have a new theory that could well back up the idea of an asteroid being to blame – but that a sinister celestial body, too, was behind the set-up.
According to various sources, Steven Stahler and Sarah Sadavoy – involved at UC Berkeley and the Smithsonian Astrophysical Observatory respectively – have produced a theory that suggests the Sun may well have had an ‘evil twin’ or companion – one which could well have been responsible for dispatching a rogue asteroid to Earth thanks to its gravitational strength. Sadavoy claims that ‘nearly all stars form with a companion’ according to research, and it is claimed by Stahler that Nemesis – as it has been named – very likely existed a long time ago.
Despite Nemesis being referred to in the press as the Sun’s ‘evil twin’, it is thought that the equal star may have resided some 46.5 billion miles away from the star that powers our solar system – meaning that despite its huge distance away, it still could have been able to send an asteroid as a projectile deflecting into the Earth and, effectively, killing off the dinosaurs.
Will we ever know, truly, what killed the dinosaurs? The asteroid angle is always a safe bet, it seems – but the only way we are ever going to know for certain is by continuing to dig into the past and to look closely at the universe around us. Whether or not Nemesis existed – and whether or not it was directly responsible for wiping out the dinosaurs – it will likely be a debate that continues to roll on for some time, meaning that archaeologists and stargazers alike can continue to unite to search for pieces of the puzzle. Whether you subscribe to the asteroid theory or something more outlandish, it remains to be said that the mere existence of dinosaurs is fascinating enough – but will we ever find out the truth?
