The sun rising from the west is believed to be a sign of the apocalypse. Scientists make a parable simulation if the Sun rises from the opposite direction at this time. As a result, these things will happen.
NASA has indeed said that no one predicts the sun will rise from the west. "Neither NASA nor any other scientific organization predicts the Sun will rise from the west," said Bettina Inclan, NASA's Associate Administrator for Communications.
But the name is also a simulation, the point is to satisfy curiosity. It is said that Earth's climate would be much different if our planet rotated in the opposite direction than usual. That's according to a study conducted by the Max Planck Institute for Meteorology in Hamburg, Germany.
Florian Ziemen, lead author of the study and his colleagues, ran 7,000 years of computer model simulations that reversed some of the key physical processes that result from the true direction of Earth's rotation.
The model reveals a backwards rotating Earth with very different features, including diverted ocean currents, cyanobacteria waves, and redistribution of desert soils such as the Sahara Desert.
The simulation findings of the sunrise from the west were presented at the General Assembly of the European Geosciences Union (EGU) in Vienna, Austria in 2018.
In their simulations, the Ziemen research team stopped all movement of water and air, then reversed the direction of the Coriolis force, causing low-pressure systems in the northern hemisphere to rotate clockwise instead of counterclockwise as they are now.
The Sun's daily path is also reversed in computer models, causing it to rise in the west and set in the east. The results, as quoted from Weather.com:
1. The weather has completely changed
Instead of flowing from west to east, the air flow in the simulation occurs from east to west. This made the climate on the East Coast of the United States the same as the West Coast today, with conditions that were more temperate thanks to the continuous flow of air into the Atlantic Ocean.
However, it causes severe winters in western Europe, as the winds carry very cold air from Russia to the region.
2. The Sahara Desert is disappearing
In addition, this simulation also shows the Sahara Desert disappearing. The barren Middle East region receives a lot of rainfall. Instead, the southeastern US and much of Brazil and Argentina turned into desert.
In the normal rotation of the Earth, the area usually receives a lot of rainfall. Based on simulations, the desert area has shrunk to 4.2 million square miles less than Earth's current desert area.
The Earth rotating in the opposite direction also displays waves of cyanobacteria in the northern Indian Ocean. The combination of this reverse circulation, and the high biological production in the region, causes low oxygen levels at deeper depths, so microorganisms need to consume nitrate instead.
Since cyanobacteria do not require nitrate and the resulting water has low levels of nitrate, it is possible for cyanobacteria to be the dominant biological producer across vast oceans, where nutrient-deficient water reaches the surface.
"Although blooms of cyanobacteria occur frequently on Earth, their development remains on a relatively small scale," Ziemen noted.
3. Climate chaos
The Earth turning backwards may seem like a better place to some in certain areas, especially desert areas. In fact, it will create a climate chaos that will be destructive, and perhaps that is why it is called a sign of the apocalypse.
"If you are in western Europe for example, life feels much better on Earth with the current rotation pattern. Because with the opposite direction of rotation, this region will feel very cold," concluded Ziemen.
