Scientists have calculated: the Earth used to rotate in the other direction
About 4.5 billion years ago, an event occurred that changed the situation on our planet beyond recognition. Perhaps it even created the conditions for the emergence of life on it. In those distant times, the Moon appeared. Rather, it was formed after a celestial body the size of Mars crashed into the Earth. At least most scientists now believe that this is how our planet acquired a massive satellite.
Robin Canap of the Southwestern Research Institute (USA, Colorado) simulated both the monstrous collision and the formation of the moon on a computer.
It turned out that in order for the Moon to become what it is, and to be located where it is now, the Earth needed to rotate much faster. And in the other direction.
From the Kanap model it follows that 4.5 billion years ago the speed of our planet was such that a day on it lasted only 4 hours. And the Sun was rising rapidly in the west.
Thanks, then, to the Moon, or rather the nameless planet, which kicked her out. Otherwise we would have slept for two hours now. And in the eyes would ripple from the sun flickering in the firmament.
By the way, the collision skewed the Earth's axis, shifted the plane of its orbit, thanks to which we have a pleasant change of seasons.
