Simulations recreated a collision between the Earth and a protoplanet, concluding that the Moon formed within hours from fragments of the Earth, and to a lesser extent from other celestial bodies.
A new hypothesis proposed from simulations on a supercomputer Suggesting that the Moon formed in just a few hours, not millions of years, as scientists have established over time The study was published in a journal Astrophysics Journal Letter.
And the most popular theory, and according to experts the most accurate, suggests that the Moon may have formed after a collision with Earth from an ancient protoplanet about the size of Mars. increase. Over millions of years, the collision of two celestial bodies is thought to have turned part of the debris into what we know today. .
Specifically, conventional theories say that a ring of debris formed around the Earth after the collision, which over the years coalesced into the sphere we see today.
scientists We wanted to test this hypothesis and reproduce the effects through simulations on a supercomputer. Designed to mimic gravitational logic and fluid forces acting on objects. They were therefore able to reproduce the impact results.
Simulations lead to new conclusions about how the moon formed
That was how they concluded what happened next. Formation of the Moon from fragments of the Earth itself and small fragments of the protoplanet ejected after the collision In just a few hours, they became satellites of nature.
This explains why samples analyzed from the moon have similar compositions to those found on the ground. Researchers will need to study rock and dust samples excavated deep within the moon’s surface to support their hypothesis. .
for it They will have to wait for the return of the next Artemis mission that will start soon This will eventually send a human crew to the moon and bring back new samples to be analyzed.
“These and many other missions and studies will eliminate further possibilities, narrow down the true history of both the Moon and the Earth, and learn more about how planets form throughout and beyond our solar system.” It always helps me learn.” science alertJacob Keguereis, a computational cosmologist at Durham University in the UK, who helped create the simulation.
