Earth ring theory may shed light on an unexplained ancient climate event, scientists say

And now, scientists hypothesize that Earth may have sported its own ring some 466 million years ago. During the Ordovician Period, a time of significant changes for Earth’s life-forms, plate tectonics and climate, the planet experienced a peak in meteorite strikes. Nearly two dozen impact craters known to occur during this time were all within 30 degrees of Earth’s equator, signaling that the meteoroids may have rained down from a rocky ring around the planet, according to a study published September 12 in the journal Earth and Planetary Science Letters. https://kra15-at.com kra22 cc “It’s statistically unusual that you would get 21 craters all relatively close to the equator. It shouldn’t happen. They should be randomly distributed,” said lead author Andrew Tomkins, a geologist and professor of Earth and planetary sciences at Monash University in Melbourne, Australia. Not only does the new hypothesis shed light on the origins of the spike in meteorite impacts, but it also may provide an answer to a previously unexplained event: A global deep freeze, one of the coldest climate events in Earth’s history, may have been a result of the ring’s shadow. Scientists are hoping to find out more about the possible ring. It could help answer the mysteries of Earth’s history as well as pose new questions about the influence an ancient ring could have had on evolutionary development, Tomkins said. _________________ Adres URL jest ukryty dla gości, należy się zarejestrować i zalogować, aby zobaczyć hiperłącze |
