What would happen if the Earth was really flat?

What would happen if the Earth was really flat? 86

The Earth is spherical, but the belief in a flat Earth refuses to die. A revealing blog from the Lamont-Doherty Earth Observatory at Columbia University explains what would happen if the Earth was really flat.

First, a flattened planet such as the one that defends the Flat Earth Society may not have gravity. It is not clear how gravity would work or be created in such a world, says Lamont-Doherty geophysicist James Davis . It is a big problem, since gravity explains a wide range of terrestrial and cosmic observations. The same measurable force that causes an apple to fall from a tree also causes the moon to orbit around the Earth and all the planets orbit around the sun.

People who believe in a flat Earth assume that gravity acts directly, but there is no evidence to suggest that it worked that way. What we know about gravity suggests that it would pull toward the center of the disk that forms the so-called flat Earth. That means that it would only pull down at a point in the center of the disk. As it moved further and further away from the center, gravity would pull more and more horizontally. This would have some strange impacts, such as sucking up all the water towards the center of the world and making trees and plants grow diagonally, as they develop in the opposite direction to the pull of gravity.

Then there is the Sun. In the scientifically supported model of the solar system, the Earth revolves around the sun because the latter is much more massive and has more gravity. However, the Earth does not fall to the Sun because it travels in an orbit. In other words, the sun’s gravity is not acting alone. The planet is also traveling in a direction perpendicular to the gravitational pull of the star; if it were possible to deactivate that gravity, the Earth would shoot straight and come out of the solar system. In contrast, the linear pulse and the sun’s gravity combine, resulting in a circular orbit around the sun.

The plane model of the Earth locates our planet at the center of the universe, but does not suggest that the Sun orbits the Earth. On the contrary, the sun rotates on the upper side of the world like a carousel, emitting light and heat downwards like a desk lamp. Without the linear and perpendicular impulse that helps generate an orbit, it is not clear what force would prevent the Sun and the Moon from hovering above the Earth, says Davis, instead of hitting it.

Similarly, in a flat world, artificial satellites would probably not be possible. How would you orbit a plane? “There is a series of satellite missions that society depends on that simply would not work,” says Davis. For this reason, he says: “I can not think how GPS would work on a flat Earth.”

If the Sun and Moon simply revolve around one side of a flat Earth, there is likely to be a procession of days and nights. But it would not explain the seasons, the eclipses and many other phenomena. The Sun should also be, presumably, smaller than Earth so as not to burn or crash into our planet or the Moon. However, we know that the Sun has more than 100 times the diameter of the Earth.

In a flat world, artificial satellites would not be possible.

The depths

Deep beneath the earth, the solid core of the Earth generates the planet’s magnetic field. But on a flat planet, that would have to be replaced by something else. Maybe a sheet of liquid metal. That, however, would not rotate in a way that would create a magnetic field. Without a magnetic field, charged particles from the sun would fry the planet. They could eliminate the atmosphere, as they did after Mars lost its magnetic field, and air and oceans escaped into space.

The movement of the tectonic plate and the seismicity depend on a round Earth, because only one sphere fits all the plates in a sensible way, says Davis. The movements of the plates on one side of the Earth affect the movements on the other. The areas of the Earth that create bark, such as the mid-Atlantic mountain range, are counteracted by places that consume bark, such as subduction zones. On a flat Earth, none of this could be adequately explained. There should also be an explanation of what happens on the edge of the world. One could imagine that it could fall, but that would probably endanger the proposed wall that prevents people from falling out of the world in the form of a disk.

Perhaps one of the most striking oddities is that the proposed map of the flat Earth is totally different. Place the Arctic in the center while Antarctica forms an “ice wall” around the edges. In such a world, traveling would be very different. Flying from Australia to certain parts of Antarctica would be, for example, an eternity: you would have to travel through the Arctic and both Americas to get there. In addition, certain feats of the real world, such as traveling through Antarctica (which has been done many times), would be impossible.

Contrary to popular belief, it is a mistake to think that many societies of serious and educated people once truly believed in the theory of the flat Earth. “With few extraordinary exceptions, no one educated in the history of Western civilization since the third century AD believed that the Earth was flat,” said historian Jeffrey Burton Russell in 1997. “A round Earth appears at least since the century VI before Christ with Pythagoras, who was followed by Aristotle, Euclid, and Aristarchus, among others, observing that the earth was a sphere, “adds Davis.

Polar vortex: “wild” winter is coming in the US, Northern Europe and East Asia after the 16th of January

Polar vortex: "wild" winter is coming in the US, Northern Europe and East Asia after the 16th of January 99

In the upper atmosphere above the North Pole, experts saw a rapidly swirling vortex of cold air that could bring severe frosts to the United States, Northern Europe and East Asia. Serious cold snap and snowy weather are expected after January the 16th.

Snowfalls and a cold snap hit South Korea since the start of 2021, hitting historic snow maximums and temperatures. In the country, for the first time since 1964, television and newer communications are sending people cold snap warnings:

The situation is similar in Japan, where a new snow storm hit historic highs:

On January 7, the thermometer In Beijing dropped to -20 degrees Celsius, breaking the 1966 record. In other regions of China, the temperature is also not sugar, and you can only move around in special uniforms:

The cold even reached Taiwan, where the temperature in some areas dropped below freezing point, snow poured down and people realized that rice terraces can be used as a ski jump:

Even more snow went to Spain, where on January 6, 2021, a temperature of -34.1 ° C was recorded – the lowest on record. After that, a snow storm hit the country, which has not been seen for 80 years:

The same thing happens in Canada and in the northern states of the United States:

It seems that after a stratospheric warming, the subpolar vortex began to split:

The vortex itself is a standard phenomenon. However, this time experts were surprised at his movement. It is possible that in the near future it will be divided into two parts. 

Scientists associate the strange behavior with the changed climate in the Arctic, which has become warmer. From September to December, the amount of ice cover decreased significantly.

The polar vortex is a low-pressure region located in the stratosphere and filled with cold air. When the jet stream of air that holds the vortex weakens, the low pressure area moves south. 

As the ice shrinks, more moisture will move inland. It will turn to snow, so snowfalls are expected. Snow, in turn, reflects heat, leading to a cold snap.

Hospital in Naples was evacuated after a new, huge sinkhole appeared

Hospital in Naples was evacuated after a new, huge sinkhole appeared 100

Eyewitnesses said they heard a loud crash at dawn when a huge hole in the ground formed outside the Ponticelli Ospedale del Mare hospital in eastern Naples.

Early in the morning of January 8, 2021, a sinkhole occurred in the parking lot of a clinic in Naples. The depth of the formed cavity is about 20 meters, the total area of ​​the hole is about 2,000 square meters.

No casualties were found at the scene; firefighters say the sinkhole “affected an area of ​​about 500 square meters” and engulfed several cars parked near the hospital.

As the press writes and as a little can be seen from the videos, rescuers and firefighters were running around the pit together with the governor of the area.  But who should be there in the forefront are Italian geologists, since Naples stands in the very center of the volcanic system known as the Phlegrean Fields.

If the surface collapsed, moreover – the surface reinforced with concrete and reinforced from below with some kind of communications, then we are talking about serious soil deformations caused by the activity of magma.

Italy has been in doubt since the summer of 2020, because swarms were observed there in very atypical places in May, and according to the forecasts of old Italian seismologists, who had witnessed many strong earthquakes, it should have boomed in the August region.

Fortunately, nothing bad happened to Italy and there was no big earthquake. But, since there are swarms, it means that something is being prepared, the magma is gathering strength. 

Following this particular sinkhole event – an obvious sign that a major earthquake in Italy is already very close.

A new great pandemic cycle has begun (again) in China

A new great pandemic cycle has begun (again) in China 101

In the first months of 2020, the whole world with a certain fright followed the events unfolding in China, where people fell on the streets during the day and astronauts wandered, and in the evening crematoria began to smoke. And now, with the onset of December, the cycle seems to be repeating itself.

Shunyi area in Beijing, where the authorities announced “wartime status” the day before. As you can see in the videos, thousands of people are lined up in the queue for mandatory testing:

Dalian city, where “wartime” is also declared. Neighborhoods are blockaded, people are walled up in entrances, familiar characters of George Lucas roam the streets:

Chinese ‘rescuers’, before performing a combat mission:

Chengdu City:

Daluo Port, Yunnan – tourists came for adventure and they received the ‘time of their life’ after leaving the ramp:

If something happens in Beijing, it does not mean that tomorrow the same will happen everywhere. However, the trend towards such dynamics is observed and, as the practice of the first wave of the pandemic has shown, all countries and people, to one degree or another, have taken into account the ‘Chinese experience’. 

Therefore, one must think that everything will now be in peace, as in spring – a new global round of the fight against the Covid has begun in China, a new great pandemic cycle!
