Misterious 9th planet could cause the human extinction
Scientists predict that the 9th mysterious planet which destroyed life on Earth millions of years ago, may soon return.
Earlier this year, scientists have found evidence of the 9th planet which is known as Planet X in the solar system, located in the Kuiper belt (between Mars and Jupiter).
This is a disc-shaped area including comets and larg asteroid outside Neptune. According to the study, Planet X is 10 times bigger than Earth.
Evidence of the new 9th planet appeared earlier this year
Daniel Whitmire, a retired astrophysicist who worked in Louisiana University (America) suggests the hidden planet is responsible for Earth's periodic mass extinctions -- like the disappearance of the dinosaurs.
Dr. Whitmire gave this opinion position for the first time 30 years ago. He admitted that the current evidence about Planet X is not entirely consistent with the predictions he had ever given inspite of the uncertainty.
Dr. Whitmire said Planet X orbits the sun, its tilted orbit slowly rotates and Planet X passes through the Kuiper belt of comets every 27 million years. This orbit causes comets to be knocked into the inner solar system.
Planet X may cause meteor shower that caused the extinction of life on Earth.
A periodic invasion of comets results in violent collisions. Those that miss Earth disintegrate in the inner solar system and dim the sun's solar energy, cooling Earth.
In 1885, the study on paleontologist showed the hypothesis that meteor rains occured regularly 250 million years ago. More recent studies found evidence indicating the event longer dating from 500 million years ago.
Previously, in the 1980s and 1990s, some people believe that a dwarf planet named Nibiru or Nemesis, came too close to Earth every 36,000 years, was the reason causing the extinction of the dinosaurs.
However, many people believed that the existence of Nibiru and Nemesis is nonsense until the California Institute of Technology
discovered the existence of the 9th planet.
