Theories abound on what killed the dinosaurs. Was it global warming? A meteorite or comet strike? An interstellar cloud? So many potential culprits, but most scientists now agree that it was most likely a meteor that crashed into the earth, landing near the modern day Yucatan peninsula and ultimately leading to their demise.
So case closed then? Not so fast. A new research paper has suggested that it may have been the mysterious Planet X, also known as Nibiru, a theorized ninth planet rotating out at the edges of the solar system, that dislodged the comet or meteor that ultimately killed the dinosaurs.
According to astrophysicist Daniel Whitmire, who is based at the University of Arkansas, the enigmatic Planet X has been causing extinctions for millions of years, and even operates on a relatively regular cycle. Every 27 or so million years the planet dislodges meteors and comets in the outer rim, and sends them flying into the inner rim. If one of these comets or meteors were to hit the earth, it’ll be game over for the life on our planet.
Whitmire claims that the Earth suffers comet showers every 27 million years. The only way such showers could occur so regularly, according to Whitmire, is if the comets were dislodged by a gravitational body, in this case the so-called Planet X.
Whitmire first published his theory in 1985, but over the last 30 years he has found more evidence to back up his claim. Further, an increasing number of scientists are opening up to the idea of a potential ninth planet due to anomalies and observations of objects in the far away Kuiper belt that surrounds our solar system.
This planet, even if it exists, however, might not be the Planet X needed for Whitmire’s theory to work. While evidence is mounting for a planet closer to earth, Whitmire’s proposed extinction-causing planet would need to be much further away. Read more about the study here
