Bad Travel Memories – Stream of Consciousness

Today is the fifth time I participate in Linda Hill’s streams of consciousness. To read about the rules and participate click here or here. To read my four previous entries (prompt was pre) click here “Prediction Failures and My Lucky Day from Hell”, or here “The Review Wars on Amazon – Stream of Consciousness”, or here, “Reindeer Hide Memories”, or here “25 Sweet Leonberger and Dog Photos”. I put this post on my Super-factful blog because it is factual, real events, and not related to Leonbergers. However, it is not a super fact.

Today’s prompt for Stream of Consciousness Saturday August 8, 2026, is “Travel”. Use it way you’d like. The first rule is: there should be minimal planning and no editing except typos. I did not edit but I did add a few pictures. I like adding pictures.

The first thing that came to my mind for this prompt was that I’ve travelled a lot. I’ve visited almost 50 countries, and 46 US states. I’ve been on business trips or worked in several countries. I’ve also lived in Sweden half my life and in the US during the other half of my life, and I’ve lived in five states. Most of my travel have been fun and interesting. However, not all my travel was pleasant. Below I am describing four unpleasant travel experiences.

The Salmonella Ferry

I grew up in a small town in northern Sweden in a working class family. We could not afford a lot of travel, but what we could afford was taking a trip on the ferries going from Sweden to Finland. These ferries had a car deck. You drove your car onto the car deck and then you went upstairs. The ferry between northern Sweden (Umeå or Örnsköldsvik) and Vaasa in Finland took four hours and you just stayed on the upper deck. However, the overnight ferry between Stockholm and Helsinki (or Tallin) took 15-20 hours and you stayed in small rooms underneath the upper deck. This time we took the ferry from Stockholm to Helsinki.

For dinner they had buffet with all kinds of Scandinavian dishes including dishes with eggs. Unfortunately, the eggs had a special feature and that was Salmonella. During the night more and more people started getting sick. People were vomiting and people got diarrhea. There were nearly a thousand people on the ferry and not enough bathrooms to accommodate everyone who had Salmonella. I did not get Salmonella, but I still needed to use the bathroom a couple of times. I remember people vomiting in toilets and people not able to go on time. It was an unpleasant disaster.

However, in September 1994 something much worse happened to one of the ferries. I remember because I had just started working for a Robotics company after getting my PhD in Physics and Electrical Engineering, specialty Robotics, and two people at my workplace died. It was a ferry called MS Estonia going between Tallin and Stockholm. The ramp / door for the car deck, the so called bow visor, was leaking during a storm, letting in water and flooding the car deck making the ferry unstable. It finally tipped over very quickly. Nearly a thousand people died and not many survived.

Interrogated and Held at Gun Point in the Soviet Union

When I was a high school student, I joined a group of travelers to the Soviet Union from the church I was part of at the time. The year was 1980, before Glasnost, and the Soviet authorities had temporarily hardened their authority. We tried to smuggle unwanted literature such as Russian Bibles and other books, as well as printing machine equipment and supplies for the underground movement. We planned to travel with the Stockholm-Tallin ferry, but a strike forced us to take the train all around the Baltic Sea and back down to Helsinki and then East to Leningrad, now called St. Petersburg.

I asked ChatGPT to draw me this. The tea cup in the picture happen to by chance look exactly like what we drank from.

Long story short, we were caught, at the Finland Station, and lined up at gun point, searched and interrogated in isolation one by one. While we were lined up, I said, in Swedish, “they are the cattle of dictatorship”, quoting a Swedish prime minister, who had said that about the Soviet Army. My friend Michael hit me in the stomach and said, “shut up Thomas, I am standing next to you”. I can add that a Sandinista who came there to learn guerrilla warfare was sitting with us and accidentally got caught up in our business.

After maybe 4-5 hours they let us go and they even let us into the Soviet Union. However, they gave us a guide from the KGB. She was watching us and making sure we did not misbehave but also giving us guided tours. She was nice and we got along with her. A note about history: The Finland Station was where Vladimir Lenin arrived in February 2017 setting the stage for the Russian Revolution.

Amnesia in Garmisch-Partenkirchen

When I was about 22 years old, I travelled with a group of friends from Sweden to Garmisch-Partenkirchen in Bavaria, southern Germany, to ski. We were travelling by bus. As it turned out I had a pretty bad accident in a black diamond slope that was closed because of too icy conditions. Yes, I know, I ignored the sign and the rules. Long story short, I fell badly, hit my head, had a concussion, and a badly dislocated shoulder. As a bonus I lost my memory.

My memory was gone for about three days. It was caused by shock and not by brain injury and that kind of amnesia resolves itself within hours up to a few weeks. Amnesia caused by brain injury is much more difficult to recover from. There were other weird things happening on this trip. You can read more about this trip here.

Our Hardest Goodbye (Don’t Read if you are Sensitive)

I’ve had ski accidents at other places as well, for example, Breckridge. One time I broke my finger and got some bruises in the Horseshoe Bowl in Breckenridge. However, the by far worst ski vacation I’ve ever had was not because of an accident. My oldest son and I went to Beaver Creek, Colorado, to ski, because that is what he wanted to do. My wife took the other two kids to Ohio because that is what they wanted to do.

While we were gone, we hired a dog sitter who was going to watch our four dogs, our Leonberger dog Bronco, our Labrador Baylor, our German Shepherd named Baby, and our Japanese Chin Ryu. The agreement was that she was supposed to come to our house a few times per day and then sleep over with the dogs.

However, after we had already left, she called us and told us she couldn’t do it as agreed because she was watching other dogs at her house, so she asked us if she could take our dogs to her house. Well, there was not really any choice. A few days later she called us and told us she could not find Baylor. He had been barking at night, so she put him out in the backyard. It turned out her fence was not secured and he had escaped. It was January and a cold even in Dallas, where we live. The next day he was found dead about halfway between her house and our house. He had been hit by a car, and the driver had just left him there. The kids cried and we were all traumatized. That was by far the worst vacation we’ve ever had. That was travel we will forever regret.

Super Rich

Superfact 120: The amount of wealth owned by the billionaires is roughly double as much as the poorest half of the world’s population. The amount of wealth owned by the 12 richest billionaires is more than the wealth of the poorest 50% of the world’s population. The richest 1% of the global population owns approximately 38% to 45% of the world’s total wealth.

There are at the moment of this writing 3,428 dollar billionaires in the world worth 20.1 trillion dollars together. For comparison the poorest 50% of the world’s population holds between $9 trillion to $12 trillion dollars of wealth (about half). According to this report the amount of wealth owned by the poorest half of the world is less than the amount owned by just the 12 richest billionaires. By the time you read this the numbers have probably changed (likely upwards). You can also read more in Wikipedia.

I am specifying that it is in dollars and not let’s say in the Iranian Rial. With respect to the Iranian Rial, I am also a billionaire, and you are probably too (if you own a phone or computer). One dollar can buy roughly 1,300,000 to 1,600,000 IRR. You just need $700 to be a billionaire in the Iranian Rial.

I should say that initially I was just going to list interesting statistics about the super-rich. However, I found myself surprised by the statistics, and I am sure I am not the only one. Therefore, I picked a couple of facts I decided super facts.

Wealth share of the richest 1%

The richest 1% of the global population owns approximately 38% to 45% of the world’s total wealth, which is more than what 95% of humanity own according to Oxfam. The richest 1% of the global population is not about billionaires, it may very well include you and me. Our World in Data has collected and analyzed the statistics for each country in the world. The top richest 1% in the United States own 34.78% of the wealth in the United States. The top richest 1% in Russia own 48.99% of the wealth in Russia. The top richest 1% in Sweden own 27.49% of the wealth in Sweden. The top richest 1% in the Netherlands own 13.98% of the wealth in the Netherlands. See the graphs below from Our World in Data.

As you can see from the graphs below the extreme inequality is nothing new. Europe was extremely unequal in the 19th century. The 1% owned 58.01% of the wealth in 1900. The United States was relatively equal in 1978 when the 1% owned 21.79% of the wealth. Russia became very unequal since 1995. I suggest that you play around with the graphs yourself .

Note: This post is not an implicit suggestion that we should tax billionaires more or less, and not about how or whether we should solve inequality, and it is not about politics. It is just surprising statistics regarding wealth and the reality of inequality.

Light is Beyond the Reach of Time

Superfact 116: Time and space do not exist for light particles (called photons) and not for other particles without mass either. All massless particles travel at the speed c = 299,792,458 meters per second compared to all other objects regardless of how fast those other objects are moving. Objects / particles that have mass will always travel slower than c = 299,792,458 meters per second. The speed of light, c, is not really a speed. It is a conversion factor between space and time. It is therefore a universal constant.

Light does not travel through a medium, like a sound wave, or a water wave does. There is no medium for light to travel in. Photons are massless, which means that an extremely tiny force, an infinitesimal smallest possible force, could send a photon off at infinite speed. There is no mass to hold the photon back.

However, the conversion factor between space and time c = 299,792,458 meters per second will prevent that and the photon will travel at this “speed”. Since c is a conversion factor, a physical constant describing time and space, this is not motion, or movement, in a normal sense. Space and time won’t allow any physical event to have any effect faster, and no information of any kind can travel faster than c = 299,792,458 meters per second.

One of the effects of the speed of light being a universal constant is that different observers measure different distances and time durations, and even the order of events may be in different orders for different observers. As you travel ever closer to the speed of light the time it will take to travel between two points will shrink towards zero as you approach the speed of light. In addition, the distance between the two points will shrink. You can read Albert Einsteins original paper on the topic here, and about space-time here.

This means that from the photon’s perspective there will be no time at all. A photon, or a light beam, will travel from Earth to a distant galaxy a billion light years away in an instant. It will not take a billion years. It will not take one year. It will not take one second. It will not take one microsecond. It will not take a nanosecond, or a picosecond, or a trillionth of a picosecond. It will take zero seconds. The Big Bang and the end of the Universe (if there is one) happen at the same exact moment to a photon. Time does not exist for a photon (or a gluon, or any other mass-less particle).

This is a mind-blowing fact, and it is true and important to our understanding of the Universe. Therefore, I consider it a super fact.

What does the Speed of Light Being a Universal Constant Mean ?

A spaceship on the right is shooting out a laser beam towards the left. Alongside the laser beam are four rockets trying to catch up with the light beam.
Four rockets, A, B, C, and D, are traveling along a light (laser) beam. No matter how fast they travel along the light beam, the light beam will always travel c = 299,792,458 meters per second faster than they do. I generated this picture with the help of ChatGPT.

The first thing to acknowledge about the speed of light (in vacuum) is that it is a universal constant as explained in my post “The Speed of Light in Vacuum Is a Universal Constant”. However, I am explaining this fact slightly differently in the next few paragraphs with the help of the picture above.

In the picture above we are emitting a light beam from our spaceship using our super laser. There are also four rockets that travel along the light beam. The rocket on the lower right (rocket A) travel at 1% of the speed of light v = 2,997,924.5 meters per second (or 2,998 miles per second). That is extremely fast, but much slower than light. You would think that the light beam would travel a little bit slower compared to this rocket at the relative speed c – v = 299,792,458 – 2,997,924.5 = 296,794,533.5 meters per second. But it doesn’t. The light beam is still speeding ahead of rocket A at exactly c = 299,792,458 meters per second.

What happens if you compare the beam with the rocket in the lower left (rocket B)? That rocket travels at 10% the speed of the light beam. Shouldn’t the light beam move 10% slower compared to that rocket? No, the light beam speeds ahead at exactly c = 299,792,458 meters per second compared to rocket B, once again.

Now take rocket C in the upper right corner. It also travels along the light beam but at half the speed of light. Shouldn’t the light beam travel at half of the speed of light compared to rocket C? No, it will stubbornly travel at exactly c = 299,792,458 meters per second compared to rocket C. Not less and not more.

The same is true for the rocket in the upper left, rocket D. It travels at 99.99% of the light speed compared to us in the spaceship, and yet the light beam will stubbornly travel at exactly c = 299,792,458 meters per second compared to rocket D. Not less and not more.

The universal speed c = 299,792,458 meters per second is not so much about light. As mentioned, it is a conversion factor between space and time. You take this conversion factor with you everywhere you go and regardless of how fast you move. That’s the way time and space works.

The fact that the speed of light is a universal constant that is exactly the same for all observers, no matter how fast they move, should tell you that it is not a speed in a normal sense. It is not really a “speed” at all. As mentioned, it is a conversion factor between space and time. Light isn’t really travelling super-fast. It is just conforming to the geometric reality of time and space, and to us it looks like it is travelling at the speed c = 299,792,458 meters per second.

The Space-Time Interval for Light is Zero

I mentioned that from the photons perspective time does not exist but that from our perspective light travel through space or seem to travel through space and that takes time. However, for us space and time are separate things. If you combine them and measure space-time intervals instead you get a more complete picture. In 3D space you get the distance between two points by adding the differences between the coordinates using Pythagoras theorem, s^{2}=x^{2}+y^{2}+z^{2}. (x, y, and z, are differences in the coordinates) As long as you are consistent with the units you will always get the same distance regardless of position and orientation of your coordinate system. You can read more here.

If you add time to Pythagoras theorem you will get the space-time interval, which interestingly enough is the same for all observers. There is no time dilation or length contraction in the interval. s^{2}=x^{2}+y^{2}+z^{2}+(it)^{2} As you might suspect, intervals involving light travelling from one event to another will always be zero for all observers, and not just from the photons perspective. And again, the same applies to all massless particles. Below are the Pythagoras formulas for different versions of the interval. In the top picture it is assumed that the conversion factor c = 299,792,458 meters per second has already been baked into to the time variable and in the bottom it has not. This is not any stranger than converting feet to meters.

The image shows three formulas for the spacetime interval Euclidian: “(s^{2}=x^{2}+y^{2}+z^{2}+(it)^{2}”.  For Time like intervals, the standard form: “(s^{2} = t^{2} – (x^{2}+y^{2}+z^{2}))”. For distance like intervals: “(s^{2} = ((x^{2}+y^{2}+z^{2}) – t^{2}))”. | Light is Beyond the Reach of Time
The three formulas for the spacetime interval above all assume that the unit used for time is the time it takes light in vacuum to travel the distance unit used. If that is meters, it would be the time it takes light to travel one meter. The top formula is the Euclidian form of spacetime. It contains only the ‘+’ operator at the expense of adding the imaginary number (square root of -1) in front of the time coordinate. The second form is typically used with time like intervals and considered the standard form. The third form is used when the distance between two events is larger than the time distance, or distance like intervals.
The image shows the formulas for the spacetime interval with the constant representing the speed of light in vacuum “(s^{2}=x^{2}+y^{2}+z^{2}+(ict)^{2}”,  “s^{2}= (ct)^{2} – (x^{2}+y^{2}+z^{2})” and “(s^{2}=x^{2}+y^{2}+z^{2}-(ct)^{2}”.
If you measure the space coordinates in meters and the time in seconds you must adjust the units to match by inserting the speed of light in vacuum c = 299,792,458. The three forms of the space interval now have the constant c attached to the time coordinate.

What about the speed of light in water ?

It is well known that the speed of light in transparent materials such as water and glass is slower than the speed of light in vacuum. The speed of light it water is about 75% of the speed in vacuum and about 70% or less in glass (depending of the type of glass) compared to the speed in vacuum. In some materials the speed of light can be much less than that. This seems to violate what I said above about the speed of light always moving at c = 299,792,458 meters per second for all observers regardless of their speed.

What is going on is that when light moves through matter it is being absorbed and emitted as it “travels” between the atoms in the material, and this absorption and emittance process takes time. This time is extremely short but long enough to be measurable. As the photons move in between the atoms they travel at the “speed”  c = 299,792,458 meters per second, the time to space conversion factor I’ve been talking about. See the illustration below.

From left to right, an atom absorbs a photon, which excites an electron that jumps into a higher orbit. Then it emits a photon and the electron falls back to the ground state again. | Light is Beyond the Reach of Time

More about the mass of a Photon

I’ve said photons have no mass. According to Einstein’s theory of special relativity, time does not pass (or effectively “exist”) from the perspective of a massless particle. However, this is the intrinsic mass or so called proper mass or invariant mass. It is the mass of an object as measured by an observer who is completely at rest relative to it. This intrinsic mass is the mass that a photon does not have.

The mass of an electron is 511 Kilo Electron Volts, which is  0.0000000000000000000000000009109 grams. That is the intrinsic mass of the electron. If an electron is sped up to close the speed of light its mass increases and goes toward infinity. If its speed is very close to the speed of light its mass could be much bigger than that of the entire Universe. That’s because as you are increasing the speed of the electron, you are increasing its kinetic energy and as you increase the total energy of the electron you also increase its total mass according to E = mc2.

As the electron’s speed approaches the speed of light the kinetic energy goes toward infinity. That is one reason why it is impossible to travel at exactly the speed of light for anything but massless particles. Infinite energy and infinite mass are not realistic. We, the objects that have mass, can move closer and closer to light speed but never get there.

However, the intrinsic mass for photons is zero and therefore the photon is travelling at exactly the speed of light, c = 299,792,458 meters per second. E = mc2 still applies to light but the mass is not the intrinsic mass, which is zero, but the total mass, and the total mass can pretty much take on any number.

What about Warp Drives ?

So, nothing with mass can travel at the speed of light, and nothing can exceed it. What about the warp drive in Star Trek? As I said, the speed of light is not really a speed but the conversion factor between time and space. It is a geometric fact of space-time. That is a pretty difficult reality to get around, just like it is pretty difficult to push Earth out of its orbit by pushing on the floor. However, there is a way to cheat and that is to stretch space-time itself. This is theoretically possible, but it requires colossal amounts of mass-energy and enormous amounts of negative energy. We don’t even know if negative energy exists on a macroscopic scale.

So, no one knows if a warp drive is possible, and if it isn’t, then we are stuck moving slower than the speed of light, which would make interstellar travel very difficult and inconvenient.

Richard Feyman’s Lecture on Why Light Is NOT Moving Through Space?

The YouTube video below is very long, 48 minutes. However, Richard Feyman, Nobel prize winner in physics, has a knack for explaining extremely abstract concepts so that they are easy to understand. If you are very interested in this topic and have some extra time, this is a fascinating lecture. He certainly explains this topic better than I can.

Russels Paradox

Super fact 111 : Russel’s Paradox is a logical contradiction discovered in 1901 that showed that the mathematical discipline of “Set Theory” was fundamentally flawed. Mathematicians had naively assumed that any definable property can be used to form a collection (or set) of items, but that is not true. An example of the Paradox is “A male barber shaves all men who do not shave themselves and only men who do not shave themselves. Does he shave himself?” Both “yes” and “no” are impossible answers. That is an example of an impossible set. Set theory needed an exclusion of such impossible sets.

Russell’s paradox is a famous logical contradiction discovered by the philosopher and mathematician Bertrand Russell in 1901. To solve the contradiction, you need to remove the assumption that any property can form a set. In other words, not every set is possible. Basically, self-reference cannot be allowed.

To take the example above “A male barber who shaves all men who do not shave themselves and only men who do not shave themselves.” Is something that cannot exist. If the barber shaves himself then he is shaving someone who shaves himself, which was not allowed. If the barber does not shave himself, then he is not shaving all the men who do not shave themselves. Either way, it does not work. Such a barber cannot exist. In general, you cannot define a set anyway you like.

I consider this a super fact because it shows that contractions can be hidden even in mathematical disciplines, and it is important because you certainly don’t want contradictions hidden in a mathematical or scientific discipline. Contradictions lead to more contradictions and lots of problems.

A Crazy Barber Story Involving Our Children

This happened soon after the September 11 attacks in 2001. In addition to planes crashing into buildings, there were attempts at biological warfare by spreading anthrax through the postal service. This is something we paid special attention to at my work because we were making postal sorting machines. It is also the reason I do not like people who write addresses in cursive.

Anyway, my wife called me at work, and she was very upset because our daughter’s hair was falling out. She touched her hair and it just fell off. She did not know what could be causing her hair to suddenly fall out, but she thought that it might have been biological warfare. I told her to call our doctor who had the good sense of suggesting that perhaps the kids had been playing barbershop. As it turned out they had. Our son confessed to cutting off our daughter’s hair. He had realized that this was bad, so he tried to put her hair back as well as he could. Afterwards, she was walking around with loose hair on top and that’s when my wife found her.

Was our son the barber who cut everyone’s hair and only those who did not cut their own hair? No because that barber can’t exist. Some sets can’t exist and you need to include that in the definition of what a set is, or in this case what kind of groups of barbers you can have.
