MEXICO: A new study carried out by Professor Michael Rampino of New York University suggests that dark matter may have had a part to play in the periodic mass extinction events that are known to have taken place throughout Earth’s history. It takes our planet roughly 250 million years to circle the Milky Way, and around every 30 million years the Sun’s orbit takes us through what is known as the galactic disk. The galactic disk is where the majority of the mass in our galaxy resides, and alongside it a thin disk of dark matter.
In a news paper published in the Monthly Notices of the Royal Astronomical Society, he postulates that the near-clockwork “plunge” of our solar system through our crowded spiral arm as it makes its 250 million-year orbit of the Milky Way galaxy.
The professor’s argument is that our solar system — and the Earth — regularly dips through a cloud of subatomic particles which wreaks havoc on the stability of our planet’s molten core and the fragile orbits of comets.
