The Fine Structure Constant is one the strangest numbers in all of physics. It’s the job of physicists to worry about numbers, but there’s one number that physicists have stressed about more than any other. That number is 0.00729735256 - approximately 1/137. This is the fine structure constant, and it appears everywhere in our equations of quantum physics, and we’re still trying to figure out why.

To top that off we know that the plank length is the smallest unit of distance that something can travel, which implies a universal pixel size.

[@davidhand9721]

​@@RovingTrollno, the Planck units don't work like pixels. The concepts of pixel resolution and physical resolution are not the same. Space does not have unitary cells. The Planck length is the minimum _distance_ that can be meaningful. If two things are closer together than the Planck length, that's fine, but nothing else in the universe can tell they aren't just one thing. It's similar to how resolution works in a microscope. No matter how many magnifying lenses you use, you're never going to see two distinct objects closer together than the resolution.

[@RovingTroll]

@@davidhand9721 that's basically a pixel

[@davidhand9721]

@@RovingTroll it really isn't, though. Pixels are evenly spaced. Planck lengths are not. With pixels, you can resolve two objects less than a pixel apart if they are on opposite sides of a boundary between pixels; both objects will light up a pixel. However, two physical objects less than a Planck length apart can never be resolved. There are no Planck length boundaries; space is continuous in QM. There are a variety of properties in QM that are quantized, i.e. they can only be integer multiples of some minimum unit. Space is not one of them. Planck units aren't generally related to quantization. For example, the Planck mass is the _maximum_ mass of a single particle, and that particle would be a black hole with an event horizon surface of one Planck area. I guess you could think of the Planck mass as the minimum black hole mass, but it's absolutely huge on the particle scale. It's roughly the mass of a dust mote. The same applies to the Planck time. Time is continuous also, so it doesn't represent something like a frame rate. I hope that clears up the confusion.

Some alien civilization wanted to make a fully simulated space game. One programmer set a constant as 1/137 during development, then left the dev team. After a while some other programmer went over the code and couldn't figure out what the constant was for. He commented the code saying "I don't know what it does or why it has that value. When deleted the whole universe breaks down so don't touch it."

[@Pallidum]

The fact that it's not exactly 1/137 is due to a rounding error in an earlier version of libuniverse. This has been kept in the code for legacy compatibility.

Astrophysicist Arthur Eddington was fascinated by pure numbers. He promoted the "Eddington number, " which he calculated to be 10E80 protons in the universe (current estimate). He used that number and a complicated formula to derive the fine structure constant which had been measured to be 1/136 (at the time). Later, when alpha was measured more accurately and determined to be 1/137, Eddington revised his formula so that it now equaled 1/137. He was then known as "Arthur Adding-one." On the other hand, he's also the guy who put Einstein on the map.

This speaks to my comment. Humans are still small minded animals who are absolutely dumbfounded by patterns and will go to painful lengths to claims that 1/137 (0.007299270072993) is the same as 137 is the same as 137^2 (18,769 ) and that there is *clearly* SOME MEANING behind similar numbers randomly popping up in completely unrelated places. It’s infuriating and yet mildly reassuring to know that our greatest minds are susceptible to human fallibility just like the rest of us.

[@hkumar7340]

Adding-one was also the one who publicly (at a Royal Society meeting) trashed Chandrasekhar Subramaniam's finding, that stars whose mass exceed the Chandrasekhar Limit could end up as a black hole due to gravitational collapse. Eddington did not like Chandra's result because it went against a grand theory of the universe that he (Eddington) had propounded. So, instead of demonstrating the logical shortcomings of Chandra's paper, Eddington said, "I am sure that there must be a law of the universe to prevent such an absurdity from occurring." The 'absurdity,' of course, being the black hole. Science progresses one funeral at a time!

[@s3cr3tpassword]

We had a professor in grad school who is obsessed with the fine structure constant. Whenever he gets to the chapter with α, he would go off on a tangent about how peculiar it was. We made him a meme amongst the grad students. Whenever new grad students join, they would see α or 1/137 all over the TA and RA office and wonder what’s up with that. We just tell them to wait till they take that one professor’s class. It’s grad quantum 1, so every new grad student has to take it. And sure enough, after the semester the new students understood all the memes.

It’s crazy how 4π just pops up in Coulomb’s Law. 4π steradians is the solid (3d) angle of a whole sphere. If you haven’t yet discovered steradians, that’s like 360° but for a sphere not a circle. The universe is telling us it prefers spheres, and that’s roughly what we see at every scale of organization we’ve observed.

[@julianbell9161]

It makes sense when you take into account that a sphere creates the shortest distance around a center for all points along the surface. In the case of Coulomb’s law, an electron emits an electric field equally in all directions from itself, so the force generated from that field would logically form a sphere. If it formed a cube or an oval or any other shape, that would mean some medium or something is causing an unequal amount of force from a center point

If α changed over time, does that mean the ratios between the other constants changed over time? e.g. rewrite the equation as c = e^2/(α4πε₀ℏ); either the speed of light changed over time, some other constants changed to hold c constant, or the formula for α isn't true at all times.

[@davidandrewthomas]

This is a really great question. I hope he answers it in the next video.

[@davidandrewthomas]

My guess as to the answer: it’s the minimum value of the fine structure value that is actually a constant. The value that changed over time has decreased down to approach this constant limit, and this constant limit is the α that shows up in the equation with other constants of nature.

[@rosskrt]

I would guess π changes from time to time.

[@rosskrt]

Jokes aside, as the fine structure constant is also the electromagnetic coupling constant, I would guess that IF (big if) the formula is true at all times, it's the electric permeability of the void to change over time. But that's just a wild guess, it could totally be that c was different in the past or that the formula needs adjusting to account for different energy levels. Who knows.

[@patreekotime4578]

I think that "over time" was relatively quickly during the formation of the universe. As he mentioned, higher a values mean that atoms cannot form.

I think the difference is that we know what π means in terms of how it relates to the geometry of Euclidean space; that being the constant relationship between the square of the radius and the area of a circle. The confusion around α is that nobody can figure out what relationship it is actually describing. In other words, π is to a circle as α is to a (?). The answer might lay in finding out which mathematical structure can replace the (?).

Alpha is directly responsible for the resonance frequency of the hydrogen atom, 1,420 MHz - or a wavelength of 21 cm.

It's more like a maximum resolution or stress-sensitive recursion limit, if we are going with the whole computational analogy. I'm currently keen on seeing it as a byproduct of neglecting to define a natural unit for charge. We have Planck lengths, times, masses, etc., but you can't get Coulombs (the SI unit of charge) out of there without seeing alpha as the ratio between the electron charge and the natural unit charge squared.

The Greek gematria (alphanumeric) value for Jesus is 888 888 = 37x24 2nd Prime = 3 4th Prime = 7 24 & 37 reading vertically above. 2424 is the sum of prime numbers from 37 to the 37th Prime.

Amos 3:7 3:7 or 37 is God's secret. Amos is the 37th book counting backwards from the end of the Bible. This verse is intentionally placed to draw attention to the fact that the reverse of 37 is 73. 37x73 = 2701, which is the Hebrew alphanumeric value for the first verse in the Bible (Genesis 1:1). The King James Bible, which is God's authoritative word in English was first published in 1611. 1611 = 537 + 537 + 537 5 is God's number for grace. This shows 5 concatenated with 37 three times. 373 is a representation of 37 mirrored about the 7 at the center. 373 also equals "word" in Greek gematria. The 373rd chapter of the Bible contains word# 314159 in the King James Bible (KJB). 3.14159 = pi HIS WORD is the 314159 & 31460th words seen here: "The LORD therefore hath performed HIS WORD that he hath spoken..." 2 Chronicles 6:10 I could go on and on, showing thousands of examples of God using 37 and 137 to show who He is and illustrate His plan. However, time is short. Jesus Christ is returning soon. I'll leave you with one final pairing of 37 that illustrates what is coming (pay attention to the chapter/verse notation): "For yet a little while, and he that shall come will come, and will not tarry." Hebrews 10:37 "For yet a little while, and the wicked shall not be: yea, thou shalt diligently consider his place, and it shall not be." Psalm 37:10 Notice that the 10 and 37 are flipped. This is because these verses are both talking about the same event... a convergence point of the Lord's return. It's two different sides of the same coin, and even the number 10 here is of incredible significance but beyond what I can explain in this comment. If you know God's secret of 37 (Amos 3:7), then it's clear what these two verses are referring to. God has given the address of His return with 37 and 10, but knowing how they map to His written word is key. In 2022, we were put on notice that the Lord is returning soon: "He which testifieth these things saith, Surely I come quickly. Amen. Even so, come, Lord Jesus." Revelation 22:20 God's countdown for His return is based on a reverse sequence. Even among believers, not many are aware of this. However, if you are aware of this fact, then you will know that God is encoding the year that we should be acutely aware that He is coming soon. When the notation grouping of 22:20 is flipped you get 20:22. 2022 is the year that the Lord is letting us know that He is surely coming quickly. Time is running out. Now is the time to repent and turn to Jesus Christ and accept Him as your Lord and Savior, the God who loves you and redeemed you of your sins by dying on the cross in your place. I suggest reading Romans 10:9-10 Lastly, if you want to see more incredible evidence of God's numeric signatures I suggest looking for the video, "Thy Word Be Verified [Extended]" on the channel Truth is Christ.

Wuld you believe me if I tell u that i, by coincidence came accross this number in 9th class? I wondered how many times the speed of electron 8s slower 5han speed of light. Then by dividing speed of light with orbital velocity of electron, I got this number. I strongly remembered it. At present , now 8 came across this number in thumbnail, I am quite surprised and immediately attracted towards this. Oh, what a legendary feeling😇 Btw I am from India, that's why I said 9th class.

It's a computational limit for the processor running the simulation or It's the observable error hidden in 3 dimensional limitations that is plain as day in the 4th dimension, once we know how to access it. or We only see it as a constant because of our fleeting existence; in geological/astrological time it is/has been/will be easily observed reaching that zero state and the end of existence; which you don't have to bother with when you have 4th dimension understanding and access. or It's the value that ties gravity to time; without it all gravity ~everywhere~ would act without limitation in a single instance to reach that zero state.

Ist this value linked to the complexity of the interactions possible? I saw this number emerge in chaos theory too. So i cant help thinking this number is the one that maximize the complexity of particle interactions

[@OgarnijmytoRazem]

In movie Stargate there was a scene when Ra says something like: "You advanced much, you mastered nuclear energy". I always had a feeling that advanced alien wouldn't point out something that average human think is important while in reality being just application of some more profuond science. He (she or it) would rather say something much less obvious but in reality much more important for better understanding the universe. And maybe he would say something like: "You noticed 137. That's impressive. You have a feeling it's important. You have some hypotheses about it. Go and dig dipper." And most of the contact team would be like: "What the...?" And scientists would be blown away and spend rest of their lives studying 137. And unsatisfactory ending of this story could be that some 300 years later scientists would discover that the alien was just trolling them :D

Excellent post. What is the relationship between the fine structure constant and pi? Is there one?

Putting the fine structure constant in a communication seems like a good way to make aliens think the message is just a natural fluke.. after all, it turns up everywhere and in strange places.

[@olivernorth7418]

It turns up everywhere in the ratios between values. It wouldn't make any sense at all for it to pop up encoded in binary in a transmission unless that transmission was sent by an intelligent species.

[@matchesburn]

"Putting the fine structure constant in a communication seems like a good way to make aliens think the message is just a natural fluke.. after all, it turns up everywhere and in strange places" ...Radio waves also appear everywhere in nature. But if you received one showing you an imagine of a hydrogen atoms structure, you'd realize quite quickly that it's probably not a naturally-occurring source.

[@silviafox78]

@@olivernorth7418 - what if the aliens don't have the same binary meanings as us... what if our way of saying 137 in binary is the aliens' way of saying "731" in the same coding? This makes no sense!

Easier with the value of h2 i believe?

There is a guy who is a number savant named Daniel Tammet. One of the interesting things about him (besides being able to remember numbers like Pi to thousands of places) is that when he visualizes each number, he sees textures and light in his mind. Each number has a specific sensory makeup to them. I would love for someone to contact Daniel Tammet and ask him how he feels about 137 and see what he has to say (before letting him see this video).

[@sppindrpurple1981]

@Jason Baumgartner That's amazing. Something to sit back and meditate on

[@jekkt]

he sees the number 1 as a bright light (spiritual meaning of god, the "one-ness") and the number 2 as a straight line (the geometric relationship between 1 and 2). kinda interesting how these numbers are contextualized subconciously and then presented to him in his mind.

Look up synesthesia. Number synesthesia is not the most common form, but it's not extremely rare.

The fine structure constant (α) is a dimensionless fundamental constant of physics that characterizes the strength of the electromagnetic force between two elementary charged particles. It is approximately equal to 1/137. The fine structure constant is one of the most important constants in physics, as it appears in many different equations, including the Schrödinger equation, which is used to describe the behavior of quantum systems. However, the fine structure constant is also one of the greatest unsolved problems in physics, because its value is not predicted by any current theory. There have been many attempts to explain the value of the fine structure constant, but none have been successful. Some physicists believe that the fine structure constant is simply a coincidence, while others believe that it is a sign of deeper structure in the laws of physics. One reason why the fine structure constant is so important is that it is a unitless number. This means that it does not depend on any particular system of units, and so it has the same value for all observers in the universe. This makes the fine structure constant a very attractive candidate for a universal constant, which is a constant that has the same value throughout the universe. If the fine structure constant were to have a different value, then the laws of physics would be different, and the universe would be a very different place. For example, if the fine structure constant were slightly larger, then atoms would not be able to form, and the universe would be a barren place. If the fine structure constant were slightly smaller, then stars would not be able to shine, and the universe would be dark. The fact that the fine structure constant has the value that it does is essential for the existence of the universe as we know it. This is why the fine structure constant is one of the greatest unsolved problems in physics. Physicists want to understand why the fine structure constant has the value that it does, and what its deep meaning is. Here are some of the specific questions that physicists are trying to answer about the fine structure constant: Why is the fine structure constant approximately equal to 1/137? Is the fine structure constant truly constant, or does it vary with time or space? Is the fine structure constant related to other fundamental constants of physics, such as the speed of light or the Planck constant? Does the fine structure constant have any deeper meaning in terms of the underlying structure of the universe? Finding answers to these questions is one of the most important challenges facing physicists today.
