A new study published in the Monthly Notices of the Royal Astronomical Society proposes that Earth would be in in grave danger when it passes through the Galactic disc of the Milky Way. It does every 30 million years so they say. The heavy volume of dark mater present there could heat the Earth’s core, disrupt comets’ orbits, and activate cataclysmic volcanic explosions.
Such force majeure are comparable to events that caused mass extinction in the past, similar to the comet that devastated the Yucatan Peninsula approximately 66 million years ago which leads to the extinction of dinosaur along with other existing beings.
Our solar system is anchored in the Galactic Disc of the Milky Way Galaxy. This area, swarming with stars and clouds of dusts and gas, also contains dark matters that unseen substances composed of minuscule subatomic particles which can only be perceived by their gravitational properties.
Rampino added that each time the Earth ventures through the Galactic disc, there’s also dark matter build up within the planet’s core. While the dark matter destroys each other, there’s a massive heat being produced. The resulting heat could set off volcanoes to erupt, alteration of sea level, and reversal of magnetic fields, incidents that seem to climax every 30 million years. Author Michael Rampino, a New York University (NYU) biology professor, made an analysis of the Earth’s wavy patterns as it passes through the Galactic disc. He discovered that these passages seemed to have connection with catastrophic comet collisions and mass extinction of the planet’s species.
“We are fortunate enough to live on a planet that is ideal for the development of complex life,” Rampino said in a statement. “But the history of the Earth is punctuated by large scale extinction events, some of which we struggle to explain.”
Dark matter—which is believed to compose at least 25 percent of the universe—may have the key to the answer, Rampino suggests.
“As well as being important on the largest scales, dark matter may have a direct influence on life on Earth,” he said.
The theory may seem interesting, the idea that dark matter has a direct influence on the planet Earth does not hold water at present. The new generations of telescopes and satellites may help enlighten what happens to Earth as it wanders through the Milky Way.
