Polar Nights Are Phenomenal and Cover a Large Area

Super fact 69 : Polar nights happen in the regions north of the Arctic Circle and south of the Antarctic Circle. Together the two polar regions cover an area double as large as the United States, and it includes a population of millions of people. During a polar night the sun does not rise for days, or months, up to six months. The polar nights are special, not just for the daytime darkness, but for the spectacular aurora borealis, the starlit skies, the extremely clear air, and the fact that people often lose track of time during polar nights.

It should be noted that even though the sun never rises during the polar night it may not be totally dark during the entire polar night. Part of the time you may get some light in the middle of the day, what is called polar twilight (nautical twilight or astronomical twilight). Nautical twilight tends to be bluish as shown in the photo below.

When our kids were young, we visited the Ice Hotel in Jukkasjärvi in northern Sweden. We went in March, during the American spring break, which was not during the polar night, so we did not experience it then. The polar night in Jukkasjärvi will begin December 5, 2025, or December 10, 2025, depending on how you count, and end at the beginning of January. However, the Ice Hotel was a fun way to experience a polar region. When I did my Swedish army service I spent the winter in the forest around that area, and even further north, and I experienced the Polar Night firsthand,

Photo is of a large ice table and ice chairs located in the middle of the lobby, which is filled with tall pillars made of ice at the ice hotel. Polar Nights Are Phenomenal and Cover a Large Area — The lobby of the ice hotel. Our kids are sitting around a table of ice. A chandelier of ice is hanging above the table. The light is from fiber optics, so the ice won’t melt.

During my army service we stayed in tents in the forest far away from villages and cities and we often did not use any lights. The result was that it was incredibly dark most of the time. It was so dark that I could not see my own hand if I held it right in front of my face. The upside was that the sky was filled with thousands of stars on a clear night. It is estimated that you can see between 2,500 to 5,000, even 10,000, stars in the sky with the naked eye if you have good vision and it is completely dark. You could also see the Milky Way Galaxy very clearly and easily, as well as the Andromeda Galaxy, meteors, comets, satellites, not to mention the most spectacular aurora borealis that you can see anywhere on earth. That certainly beats the 14 stars and 3 planets that you can see with the naked eye on a clear night here in Dallas, Texas, where I live now.

On one occasion I was standing guard outside the camp. We were pretending that we were at war with the Soviet Union. It was minus 40 degrees, and they forgot about me. I stood there alone in the darkness and the extreme cold for more than three hours. This was considered dangerous. The rule was no more than one hour out in the cold at a time. Once they discovered that I had been there for more than three hours they came to get me, and they apologized profusely. They were happy that I was not hurt. However, I did not mind, because my night sky view was spectacular. The night sky was so spectacular, it was to die for.

If it is cloudy and you are far from any civilization it may be pitch black in the afternoon. Even if it is not cloudy but the moon is not out it will be pitch black later in the afternoon. In addition, the air is very clear during the polar night, because the cold sunless Arctic air often contains almost no moisture and the visibility stretches for 100 miles. If you want to remain unseen in this situation it is very important to understand that even the tiniest light will be very visible, far away. Our platoon did an experiment. Someone lit a cigarette about one mile away and we could very easily see the bright cigarette even through the forest. The lesson was, No Cigarettes, and No lights!

I consider this a super fact because the polar night is a surprising phenomenon to those who do not know much about the arctic and my claims above are true and important since the polar regions are large and under threat from climate change / global warming. The polar regions and thereby the polar night also cover an area that is not small, and four million people live there.

The Midnight Sun

I can add that in the summer (northern hemisphere) you have the opposite phenomenon with the midnight sun. Just like the polar night can cause people to lose track of time so can the midnight sun. When we visited northern Sweden with our niece Jessica for my brother’s wedding, we had what is called midnight sun. Jessica was nine years old at the time. A couple of hours after we had gone to sleep Jessica woke me up “wake up Thomas, it is time to go out and play”. I protested, no it is not, it is one a clock at night and we are going to sleep. Jessica protested, she said, “No the sun is up, it is morning it is time to play”.

So, I said “Jessica, let me explain something to you. This is northern Sweden in June and here the sun is up in the middle of the night, and we are not going outside to play in the middle of the night.” After that my wife went out to play with Jessica, but I refused to go out and play at one o clock at night.

Ice Hotel Photos

Finally, I just wanted to include a few of my photos from the Ice Hotel, just for fun.

Half the World’s Population Live within a 2 Percent Circle

Super fact 57 : Half the World’s Population live within a circle that covers 2% of the world’s surface, or 10% of earth’s land area. This circle is often referred to as the “Valeriepieris Circle” or Yuxi Circle, and it is centered on southeast Asia.

This circle, has a radius of a bit more than 2,000 miles, and encompasses densely populated areas of East and South Asia, including major population centers like China, India, and Indonesia. The original Valeriepieris Circle was created by a teacher named Ken Myers in 2013 and was larger (radius 2,500 miles) than the more optimized circle created in 2015. In 2015, Singaporean professor Danny Quah—with the aid of an intern named Ken Teoh created a significantly smaller circle (radius 2,050 miles) that included half the world’s population. 4.2 billion people live in the Valeriepieris Circle, which is 5.6 times as many people as in Europe and 12.4 times as many people as in the Unites States.

I consider this a super fact because it is true, it is an important fact, and it is a surprising fact to those of us who have not come across this information before. It is an important fact because it impacts how we view our world. The circle is located far away from Europe and North America, in a part of the world that is rising quickly economically. The people in this highly populated circle have different cultures, music, literature and religions from the US and Europe. They speak different languages, and they play different sports, well soccer (the real football) is international but not as common in the Valeriepieris Circle as in Europe or South America.

Those among us who live outside of this circle, for example, in the United States or Europe, probably need to pay more attention to this half of world. Especially, if you live in the United States, it is easy to believe that the world is about us. The existence of this circle demonstrates that this view is not a realistic view.

This is a world map showing all the continents with the colors of the Valeriepieris Circle inverted. It should be noted that the circle is quite small compared to the whole world | Half the World’s Population Live within a 2 Percent Circle | The original 2013 map by Ken Myers, with the interior of the circle. — The original 2013 map by Ken Myers, with the interior of the circle.

It should be noted that the fraction of the area of the circle to that of the globe is equal to its equivalent on Earth. Again, half as many people live inside the circle as outside the circle.

Population of Southeast Asia

The countries that are part of the Valeriepieris Circle are, for example,

India (1.47 billion people)
China (1.415 billion people)
Indonesia (286 million people)
Bangladesh (176 million people)
Japan (123 million people). It is not included in the second circle.
Philippines (117 million people)
Vietnam (102 million people)
Pakistan (256 million people)
Thailand (72 million people)
Myanmar (55 million people)
and a dozen more countries.

The map shows the countries in Southeast Asia as relatively large, especially, China and India. Almost the entire right-hand side of the map is filled with Southeast Asian countries making it easy to understand how just around 20 Southeast Asian countries can correspond to half the world’s population. — Each country’s size represents the size of the population in 2018. Each little square represents 500,000 people. All 15,266 squares show where the world’s 7,633 billion peopls lived in 2018 (now the world population is 8,244 billion people).

Population Statistics

Most people know that in recent centuries the world population has grown almost exponentially but is now projected to level off sometime around the middle of this century. Europe is an interesting example. A thousand years ago Europe’s share of the world population was around 14.5%. Then came the scientific revolution and the industrial revolution and by 1900 it was 25%. As other countries around the world became industrialized Europe’s share of the world population shrunk, even though the population of Europe kept increasing, just slower. Now Europe’s share of the world population is 9%.

As countries become wealthier their population growth tends to slow down, not just in Europe, but around the world. The world’s population growth is illustrated by the image from Our World in Data below (starting 5,000 years ago, ending the year 2000) and the six minute YouTube video below from the American Museum of Natural History (starting 100,000 years ago and ending the year 2100). The YouTube video also shows the projected population decline beyond the year 2050.

The Bermuda Triangle the Big Non-Mystery

Super fact 56 : The Bermuda Triangle mystery is a myth. There is not a higher risk of disappearances in the Bermuda Triangle. To be specific, disappearances do not occur in the so-called Bermuda Triangle, or Devils Triangle, with any higher frequency than in other comparable regions of the ocean. The “mystery” of the Bermuda Triangle is largely a manufactured one, perpetuated by sensationalized accounts that often misrepresent the facts and downplay the role of natural hazards like storms.

The number of ships and aircraft reported missing in the Bermuda Triangle is not significantly greater, proportionally speaking, than in any other part of the ocean. The U.S. Coast Guard, along with NOAA, the U.S. Navy, Lloyds of London who pays out insurance for ships and aircraft lost/missing at sea, and other organizations do not recognize the Bermuda Triangle as a unique or mysterious geographic hazard. They emphasize that this is a highly traveled area where the losses are consistent with natural phenomena such as strong storms, the Gulf Stream, human error, and poor navigation, rather than any mysterious forces.

Considering all this, the number of disappearances and accidents is what you’d expect. The Bermuda Triangle isn’t any more mysterious than the Greenland square, the New Zeeland circle, or the Azores Octagon, that I just made up. I consider this a super fact because it is very likely true, and yet surprising to many people who are convinced that there really is a mystery. Furthermore, it is important because it is such a well-known myth.

Bermuda Triangle Mysteries

Just because the risk of disappearances of planes and ships is not higher in the Bermuda Triangle, does not mean that there aren’t mysterious disappearances and mysterious phenomenon occurring in the Bermuda Triangle. Some notable disappearances are USS Cyclops (1918), Flight 19 (1945), Star Tiger and Star Ariel (1948–1949), and the Witchcraft (1967). However, there are mysteries and mysterious phenomena occurring all around the world.

One of the mysterious phenomena occurring in the Bermuda Triangle is ocean swirls, and rogue waves, and methane burps might be another problem, but it is far from unique to the Bermuda triangle, and there are no magnetic anomalies in the Bermuda triangle as often alleged.

Ocean swirls frequently occur all over the world with some famous hotspots for ocean swirls by the coasts of Japan, Norway, Italy, Scotland, and Maine, USA. The ocean swirls in the Bermuda triangle might be due to movement of water between landmasses and/or the Gulf stream, but this is under investigation. There are no known giant or permanent ocean swirls in the Bermuda triangle.

As mentioned, another mysterious phenomenon is methane bubbling to the surface of the ocean. However, as can be seen in the maps in this National Geographic blog post the source of these methane burps of death aren’t typical to the Bermuda triangle. The methane hydrate field in the first map of the National Geographic blog post is mostly outside of the Bermuda triangle stretching from Cuba and up along the Florida coast. The second map, the world map, shows that these methane hydrate fields exist all around the world.

United States, Europe and the Pacific Ocean Are Bigger Than You Might Think

Superfact 11: United States, Europe and the Pacific Ocean Are Bigger Than You Might Think

The area of the United States is around 9,8 million square kilometers
The area of continental United States is around 8.1 million square kilometers
The area of Europe is around 10.2 million square kilometers
Earth’s total land area is 148.9 million square kilometers
The area of the Pacific Ocean is 165.3 million square kilometers
The area of the whole earth is 510 million square kilometers

The United States

The United States is much bigger than many Europeans think. Europe is much bigger than many Americans think. Many of us don’t realize that one of the five oceans, the Pacific Ocean, is one third of earth’s entire surface and cover a larger area than all landmass on earth. Since so many of us are surprised to hear these facts and they are not under dispute among experts, they constitute a super-fact, or a few super-facts in my opinion.

Some time ago I was talking to a Swedish friend of mine who told me something along the lines of “the United States isn’t so big as they say. We drove through half a dozen states in an afternoon.” I asked her, “which states?” It turns out that was the New England states, Maine, New Hampshire, Massachusetts, Rhode Island, Connecticut, and finally New Jersey and New York (New York city). You can do that drive in an afternoon, but you cannot drive through Texas in an afternoon, not even in a day.

The distance from Texarkana to El Paso is 1,300 kilometers and takes more than 12 hours to drive on the highway without stopping. I’ve come across many Europeans who underestimate the size of the United States. The mistake they make is that they don’t realize that while some US states are small, other states are much bigger. Just look at the map.

Europe

Interestingly Americans often make the same mistake about Europe. I quite often hear Americans claim that distances are so small in Europe. You can drive through a country in a couple of hours and the language changes. It’s a trope that seems to be repeated every time Europe is discussed on social networks.

Today, as I was talking to a friend of mine about our recent trip to Sweden and Norway, my friend told me that it was good that distances in Europe were so short so we could easily travel between the places I was telling him about. He was more than surprised to hear that was not the case. The distance between where we were Sweden and Norway was too large for anything other than planes considering we only had 10 days.

The distance from Malmö in southern Sweden to Karesuando in northern Sweden is more than 1,900 kilometers and takes more than 21 hours to drive without stopping. In fact, by area, Sweden is bigger and longer than California.

The Pacific Ocean

Last but not least. Earth has seven continents (Asia, Africa, North America, South America, Antarctica, Europe, and Australia), and five oceans (the Arctic, Atlantic, Indian, Pacific, and Southern (Antarctic) Oceans). But just one ocean, the Pacific Ocean cover a third of earth’s entire surface. This may come as a surprise to many. See the globe photorealistic 3d illustration below.
