IN the upcoming movie “Moonfall”, a mysterious force knocks out the Moon when it collides with the Earth.
In this year’s sci-fi movie and starring Halle Berry, the screen object’s inflated gravity causes a doomsday tsunami and pulls massive chunks of rock and debris off the surface. face of our planet.
It’s a far-fetched idea and it’s all a bit exciting, but can it really happen, and what effect does this have on Earth?
Scientists have busted their theory – with some suggesting that our planet is currently in a (very slow) collision process right now.
What if the Moon got closer to the Earth?
Talking to BBC Spotlight Science Magazine on Wednesday, physicist Dr Tony Cook painted a bleak picture of any near-miss encounter with the Moon.
He said that even if the Moon were half its current distance from Earth, the tides on our planet would be eight times stronger.
“There will be a lot of coastal flooding,” said Dr Cook, a lecturer in physics at Aberystwyth University. There will also be “some tsunami”, he added.
“There will be more of a gravitational effect on the Earth’s interior, so you might as well stir up and heat up some of the mantle, leading to more volcanoes and earthquakes.”
His sad photo echoes the observations of astronomer and author Gemma Lavendar.
Writing in a magazine All about space In 2018, she predicted that a flyby of the moon would trigger large, deadly waves to hit coastal regions.
“Moving the Moon closer to Earth would increase the satellite’s gravitational pull on our planet,” she wrote.
“The low tide will be lower and the high tide will be higher and any low-lying coast will be flooded.
“If the Moon were to come much closer, that is, 20 times closer, it would exert a gravitational force 400 times greater than what we are used to.
“A strong tidal bulge will be created, hitting land and causing massive flooding, with cities like London and New York disappearing under water.”
Did the Moon ever hit us?
Some scientists believe that the Moon will indeed collide with the Earth – albeit within a period of several tens of billions of years.
Our rocky neighbor is said to be spinning away from us at a rate of about 3.8 cm per year.
Over time, however, Earth’s rotation will slow down until the Moon stops moving outward.
Assuming the Solar System is not swallowed up by the explosion of our Sun then, the satellite will start to go inside until it hits our planet.
Jason Barnes, a planetary scientist at the University of Idaho, said: “The final state of tidal evolution in the Earth-Moon system will actually be the inspiration for the Moon and collisions. its impact and subsequent accretion on Earth,” said Jason Barnes, a planetary scientist at the University of Idaho. Forbes in 2017.
That’s all well and good on geologic timescales, but what about our natural satellite that suddenly fell out of space, like in “Moonfall.”
Dr Cook told Science Focus we have nothing to worry about in that respect.
There is an equilibrium between the Earth and the Moon called the center of equilibrium, which the two celestial bodies orbit, he said.
This point is closer to the Earth than the Moon, inside the surface of the Earth – if left alone, that point will not change and there is no danger of a real collision.
The trailer for Moonfall suggests that, in the film, an alien force has thrown the Moon out of its orbit.
That’s something that will take a long time and will likely require a bunch of rocket propulsion mounted to the Moon.
“You would need an enormous amount of energy to do that, and probably have to do it gently or the Moon could fall to pieces,” said Dr.
“A similar method has been proposed to change the orientation of asteroids.”
