The goal of this blog is to create a list of super facts. Important facts that are true with very high certainty and yet surprising, misunderstood, or disputed by many. This blog aims to be challenging, educational, and fun, without it being clickbait. I determine veracity using evidence, data from reputable sources and longstanding scientific consensus. Prepare to be challenged (I am). Intentionally seek the truth not confirmation of your belief.
Imagine my delight when I saw the post above. Sally is sharing my super fact 57: 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. In addition, she is promoting my Leonberger dog book for which Robbie wrote a great review. Thank you so much Sally and Robbie. Please hop over to Smorgasbord blog magazine and read it.
I started this blog, superfactful, in August of 2024. The goal of my blog is to create a list of facts that are important, not trivia, and that are known to be true yet surprising, shocking or disputed by large segments of the public. I determine what is true by evaluating the evidence I find in reliable reputable sources and if a longstanding scientific consensus is available that certainly helps. In some cases, I have expertise in the subject myself, which also helps. Whether a fact is important and surprising or disputed is a judgment call. In some cases, there are polls to help me determine how surprising or disputed the fact is. I am trying to avoid trivia and click bait, and I am only focusing on what is true, important and mindboggling.
It is a project I hope to learn a lot from, and I hope others will also learn something from reading it. We are all drowning in misinformation, false beliefs and unsubstantiated assumptions. We often know and understand less than we think. I have been bamboozled in the past and I am pretty sure you have too. If this blog can spread a little bit of light, I am happy.
In 2024 I posted 25 super facts and in 2025 I posted 53. I am hoping to one day to have collected 200 super facts. I have also made 64 other kinds of posts on this blog such as book reviews for educational books as well as other fact related posts. Below are ten selected super facts from 2025. To read the full post click the links.
That Earth is round was well known long before Columbus
Super fact 28: That Earth is round, or spherical (or closely spherical) had been known for at least a couple of thousand years by the time Columbus set sail. Columbus did not set sail to prove that earth was round, and he knew it was round.
I’ve realized that this comes as a surprise to some. To read the post click here.

EV Cars Indeed Emit Less Carbon Pollution
Super fact 29: EV Cars emit less pollution than Internal Combustion Engine, even considering manufacturing, disposal and EV Cars being charged by dirty grids.
There is a lot of misinformation about EVs including that EVs are not better for the environment. To read the post click here.

Scientists Agree that Global Warming is happening and that we are the Cause
Super fact 34: Climate Scientists agree that Global Warming or if you call it Climate Change is happening, and that it is caused by us primarily because of our burning of fossil fuels. There is a long-standing scientific consensus on these two facts because the evidence is conclusive. Typically, studies show an agreement of at least 97% or 98% among climate scientists.
Polls show that most American are unaware of the consensus among climate scientists. To read the post click here.
There is almost total agreement among climate scientists that global warming, or climate change, is happening and is caused by us. To understand why, you need to know a little bit about the impressive evidence, which for all practical purposes is conclusive. Take a look at this post “Global Warming is Happening and is Caused by us”
The green graph corresponds to “most scientists think global warming is happening (%).” The black graph corresponds to “there is a lot of disagreement among scientists (%)”. The yellow graph corresponds to “Most scientists think global warming is NOT happening (%)”. Graph taken from the Yale Program on Climate Change Communication.
Time Dilation Goes Both Ways
Super fact 38 : If two observers are moving compared to each other both will observe the other’s time as being slower. In other words, both observers will observe the other’s clocks as ticking slower. Time slowing down is referred to as Time Dilation.
Clocks slow down as you travel at high speeds. However, the person travelling think they are standing still. It is the other person who is travelling. This is confusing. To understand it click here.
In this picture Amy is traveling past Alan in a rocket. Both have a laser. Both measure the speed of both laser beams to be c = 299,792,458 meters per second. The speed of light is a universal constant.
Emissions of ozone-depleting gases have fallen by 99 Percent
Super fact 41 : Largely thanks to the Montreal Protocol in 1987 the emissions of ozone-depleting gases have fallen by more than 99%, 99.7% to be exact, according to Our World in Data. This has resulted in halting the expansion of the ozone holes and the reduction in emissions of ozone-depleting gases is saving millions of lives every year.
A gigantic victory for the environment that few are aware of. To read the post click here.

Sulfur dioxide pollution has fallen by 95 percent in the US
Super fact 44 : Sulfur dioxide pollution in the US has fallen by approximately 95% since the 1970s. This significant reduction is primarily due to regulations like the Clean Air Act. Global sulfur dioxide pollution has also fallen but not as much.
Another big victory for the environment that we seldom hear of. To read the post click here.

We Exploded Thousands of Nuclear Bombs
Super fact 48 : Since 1945 we have set off more than 2,000 Nuclear Bombs corresponding to a yield of an estimated 42,000 times that of the Hiroshima Bomb.
That we have exploded these many nuclear bombs was a surprise to me and perhaps to you too. To read the post click here.

The Euler Number Math Magic
Super fact 53 : The Euler number denoted e, is an irrational number, which like the number pi is extremely important in mathematics. In addition, the relationship between the Euler number and pi; seemingly unrelated numbers, is quite amazing, especially if you throw the imaginary number: i = square root of -1 into the mix. Euler’s formula e^ix = cos(x) + isin(x), where x is degrees expressed in radians, is mind blowing to say the least. Radians means that 180 degrees is replaced by pi, and 90 degrees is replaced by pi/2, etc. A simpler special case, but equally amazing is Euler’s identity e^ix = -1, or e^ix + 1 =0. This is amazing math assuming you understand it.
One of the most amazing math facts explained. To read the post click here.

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.
A surprise to the people who are convinced that there really is a mystery. To read the post click here.

Evolution is a Fact
Super fact 63 : Evolution is both a fact and a scientific theory. It is a fact that life has changed over time. This is supported by overwhelming evidence, while the theory of evolution provides a comprehensive scientific explanation for these changes, using processes like natural selection.
Yes, there are scientific facts, and that evolution is happening is an observed scientific fact. To read the post click here.

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,
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.

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.
The original 2013 map by Ken Myers, with the interior of the circle. Half as many people live inside the circle as outside the circle. However, it is larger and less optimized compared to the circle from 2015 below. This circle is NASA, Public domain, via Wikimedia CommonsDanny Quah’s 2015 circle, on a Lambert azimuthal equal-area projection. 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 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.

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.
