The MYSTERIOUS NUMBER that Shaped our Universe! Fine Structure Constant

[@-1-alex-1-]

The craziest thing about fine structure constant is that Pauli (who was absolutely posessed by this number), when he was sick and dying, was taken (without neither him, nor doctors realizing it) to the hospital's room no. 137.

You didn't mention Arthur Eddington who came up with a theory why the denominator of the fine structure constant must be 136. When better experiments showed it to be 137, he came up with another theory. This earned him the nickname of Arthur Adding-one. Recently, Sir Michael Atiyah revived Eddington's work from its well-deserved oblivion, embellished by yet another theory to explain the decimal places. I tried to read Sir Michael's paper: it's very well written, but I'm afraid it doesn't make much sense. He was nearly 90 and would die a few months later.

Thanks for calling attention to the inconstancy of alpha. This raises an interesting question: *Which of the factors of the fine structure "constant" is **_not_** constant?* Given the eq. for alpha (1:54), it appears that there are four basic possibilities plus their combinations. If we rule out e, the elementary charge, then there are just three basic possibilities and their combinations. This question could be upsetting, for folks are fond of saying that c, ε_0, and 2πħ are physical constants. So we could abandon our faith in the Big Bang, and it is a faith. But even this heterodoxy won't justify calling α a constant just yet. If the value of α is directly proportional to temperature, it may vary under some common conditions observed in the cosmos. For instance, it's believed that the temperature of the core of a newly formed neutron star is as high as 10^12 K. Now, the reason that you gave at 14:48 for calling alpha a constant is bs. It's merely a self-serving excuse used by the high priests and gatekeepers of The Science to talk out of both sides of their mouths. The true reason for their doubletalk will be found in their character and mentality, which differs not very much from the stereotypes of marketing flunkies, PR hacks, lawyers, democratic politicians, and Abrahamic theologians. Since it won't hurt anyone employed in The Science to break the habit of calling α what it's probably not, we could write fine structure "constant", as I have above. This doesn't help us when speaking, however, so a better name would be fine structure product or fine structure factor. If we want to comprehend things correctly and to conduct affairs successfully, we need to name things correctly, adding neither claims nor judgements which aren't justified by the attributes of named things. Habit and convenience, of course, have little to do with the correct name of a thing. If it turns out, for some reason, that α really is constant, it would still be true that it's a product as shown at 1:54 and a factor, as in the eq. for e^2.

[@SACHIN-yw4hd]

I was thinking about this.😯

[@kshitijkumar5629]

It is not that every variables or most variables are squared. For this we need to understand maths especially calculus, trigonometry, algebra. If you are comfortable, you can start with reading simple special relativity concepts like time dilation, length contraction, equivalence principle. Lots of good books exist on modern physics, from which you can take reference. Deriving E=mc² could be hard comparatively to other concepts like time dilation or length contraction , as it's calculus heavy, so you might need to be very comfortable with calculus. Now it can be considered as coincidence or something with no inherent explanation as to why many variables are squared. In 2d coordinate geometry, its very evident due to the formula we write for distances. Regards.

[@onebronx]

Most squared variables come either from integration of a linear relation (mv --> mv²/2), or just from spreading some constant value over a surface area (most inverse square laws, like a force of gravity or EM force).

[@Verschlungen]

At 8:08-8:25, those are superb graphics for explaining fine structure!! After reading about the fine structure in so many books, finally I 'get it' (completely) thanks to that graphic. A quibble regarding the alpha formula. The real formula is this... α = e^2/2hεc Note that it contains h, not h-bar, and is π-free. The real version (given immediately above) is seen rarely, but it does occur in at least the following two reputable places: McQuarrie, Quantum Chemistry, back cover, and Unzicker, Einstein's Lost Key, pp. 45 and 51. The commonly seen version, shown in this video at 2:00, is nonsensical since the explicit π and the hidden π (in h-bar's denominator) cancel one another. That's one reason to avoid the common version: π chases its own tail to say, in effect, "now multiply by 1." The other reason is that it reinforces the earthling superstition of π, regarded as mystical rather than as a useful tool for calculating circular things. (ETs will never bother trying to communicate with earthlings so long as we wallow in the dual superstition of π and the Golden Ratio.)

Think of how quickly mosquitos fly and die. And how slow tortoises move and how old they live. How light seems to be instantaneous yet still physically need to travel.

I'm not a student - in fact, I am an old man. Some of this is a little hard to follow, but maybe I just missed a few things. I know that electrons are negatively charged, but you showed them as spinning, with magnetic poles of their own. Do you know if this spin is constant? At one point, I thought you were getting close to saying this, but I never really felt it. As the electrons absorb and emit energy, you are saying they ascend and desend in the orbital path. Would that effect the spin? Maybe that was assumed in the equation, and it was just too fast for me, but rattling around in my brain are pictures of electrons that might even reverse their spin, or change their angle of spin as they approach each other, kind of like the earth's polar shift that is going on, if you can see where I am going with this. Appreciate any input - thanks

does that mean, that the fine structure constant can have different values depending on the temperature/energy of the locality (like the core of stars; at collision points etc)? And "if" so, how does it affect the particles/fusion reactions? Or would it be irrelevant when only plasma is involved? Arvin and Matt are the only two ppl that always leave me with more questions after gettimg an answer - LOVE it!

The different values only apply at the temperatures which were present at close to the big bang. The core of stars is much cooler than that. At these temperatures, the constant does not vary enough to make a big difference.

He said it only went from 1/137 to 1/127 when the temperature got up to a quadrillion degrees. At even a billion degrees, and that's about as hot as any star can be, it would be a million times closer to 1/137 than 1/127 is, in other words still very close to 1/137.

Universe can be discontinuous or continuous depending on the true nature of space time (see Loop Quantum Gravity for example). But it has nothing to do with the other quantum fields because they all are embedded in our (supposedly continuous) spacetime.

[@DFPercush]

Wave functions are continuous. Interactions are discrete. The continuous wave function tells you the probability that a certain discrete event will happen. Often times, in the macro world, there are so many interactions that we can practically think of things as continuous, like radio waves. They're still just a bunch of photons, but they involve billions of times more photons than visible light. We just can't practically isolate a single radio photon. So it makes sense to use a continuous field model when designing antennas. All models are approximations. You use the one that answers the question you need to ask. Newton's laws will get you to Mars, even though they are not the complete reality.

There are also coupling constants for the weak and strong nuclear interactions. Computing a coupling constant for gravitation, alphaG, is possible only if one makes arbitrary assumptions about what fundamental particles to consider. AlphaG is known only to about 1 part in 10,000, which is much less precise than our knowledge of alpha and beta. The minimum electric charge we can observe is that of a proton or electgron. In other words, electromagnetism is quantised. Hence it is natural to ground the study of electromagnetism in the repulsive force between two electron or protons, or the attractive force between an electron and a proton. There is no comparable quantisation of gravitational attraction. Both alpha and beta are dimensionless, meaning that their values do not depend on one's choice of measurement units. If we want to advertise to the Milky Way our existence as a superintelligent species, broadcast repeatedly 137036 x 1836153 in binary. The values of alpha and beta ground all of electromagnetism. Chemical bonds are electromagnetic. Biology is grounded in biochemistry and hence in chemical bonding.

This is another great presentation. Gosh, our knowledge of the Universe has changed so much since my High Scool days in 1966. Expanding Universe is Expanding Minds. Thanks Arvin.

[@ArvinAsh]

Glad you enjoyed it!

[@brianwright9215]

Beautiful video 🙌🏿 Thank you Arvin 🙏🏿

[@bitterlemonboy]

Wow. Amazing. Isn't the universe and everything that has ever existed just one big piece of art?

[@stephenland9361]

"I don't know", is a great answer in science. It means there is more work to do.

[@foreverraining1522]

Hi Arvin, can you do a video on the Penrose theory of conformal cyclic cosmology.

[@grayaj23]

Seconded

[@darrennew8211]

The value isn't 137. They thought it was 1/136 for a while, and the numerologists thought that was special too. Read Feynmann's QED if you want to learn more about this. That said, I didn't know it wasn't a contant at all. Very cool.

[@sphinxtheeminx]

Marvellous stuff and way beyond my IQ level but I still find your channel exhilarating.

[@ekananda9591]

There is always something new to learn from this channel ❤️

[@Owdren]

I think a possible answer to the question of why it is such a random number might be closely related to the many-worlds theory. If life and the universe did not exist because the value of the fine structure constant was not 1/137, then no life would be around to ask why such a value. Many questions about why the constants of the universe are so precise and unpredictable might actually be answered by the many-worlds theory. We could simply be one of or the only universe hospitable to life. Forgive my english I'm a french 15-year-old :p

[@DFPercush]

Your English is perfect! I had no idea until you said you were French. But yeah, many questions can be answered by the anthropic principle and many worlds. "Why is x?" --> "Well somewhere there is not x, but there's nobody around to ask why." :P

[@BirdTho]

Because it would be horrible if the universe was deliberately created, that someone comes up with a many world theory?

[@magicmulder]

2:53 Funny, when I first heard about “close to 1/137”, the first thing that popped into my head was “I wonder what it’s like in a different base”.

[@paulisaacson6044]

89 base 16

[@Kya-Kab-Kaha-Kyu-Kaun-Kaise]

Great video! So if the value is changing for this constant, would it be possible it will change again in say a million years and we just happen to calculate the value in these conditions of the universe today. ? I m not against the fine tuning theory but i highly doubt its validation.

[@ArvinAsh]

Unlikely. We are not likely to approach the temperatures near the big bang in the current trajectory of the universe.

[@desi_patriot]

Ur explanation is SUPERB.. a template for others

[@avadhutd1403]

Thanks for another great video Wish you happy new year 🎊🎁 Is there possibility that other universe exist with diff value of Alpha and other constants with generate whole different physics law and property ? According to my knowledge of they existed we cannot communicate with them is there any way to create them in lab or contact them

[@pansan4967]

It could be, but as you said, we could not communicate with these other universes. So it doesen't really matter. You can kinda make up your own universe with its own laws of physics in your head. But your mind is limited with the boudaries of our universe, so have fun.

[@ivornworrell]

God invented Mathematics, man merely discovered that which God ALREADY invented, so @0:14 why was Pauli going to seek answers from the devil when both he AND the devil are just created beings? Shouldn't Pauli be seeking wisdom from God instead, Who is All Wise? Salaam.

[@pansan4967]

@@ivornworrell This does not explain anything. Humans always put god into the place where we can't explain a phenomena, but we always push forward and find ways to explain even the complexed things. First it was God who created humans, now we know better, first it was God that makes the sun hot and glow, now we know better. We put god as an explanation to why the moon orbits the earth, now we know better. Putting god as a solution to a problem makes yourself ignorant to the problem itself. Do not underestimate research done by humans. Sure, god could have done the big bang. What gives, because it is a time where we can't find any answers yet. Maybe in a few hundred years we have a solution to that problem and the existince of god shifted again as history and science pushes forward. God is just a placeholder for things we don't understand yet.

[@darkace37]

Top tier content, thanks Arvin.

[@DrGalile0]

Amazing video (as always) and amazing channel! However, "life" = "life as we know it". Different alpha might just mean different life :)

[@ArvinAsh]

Well said!

@@ArvinAsh, you have one of the best channels explaining physics out there! I am a teacher too (biology), and I am just stunned by how well you can explain complex topics - bravo!!

[@camilosantos4380]

In the book “ASCENSO, Civilization of the Humus” published on Amazon, a theory is proposed that unifies relativistic and quantum physics, supported by a mathematical and analytical calculation of the fine-structure constant (1/137) for the 3rd dimension and the other dimensions that make up the Universe. It includes parallel and mirror universes. It proposes a mathematical theory of how the multiverse should be structured and the action of dark matter and energy within it

[@dragovian]

While it is interesting that things like α and π, are ratios, there are a lot of constants, like c. Couldn't we reverse engineer starting from any of these values, (like i.e we say c = 1), to find the actual mathematical model, that the universe was created? If I had created it, the values would be proportionate of one another, or atleast somehow connected

[@harrkev]

This has already been done. Look up "Planck units."

[@Raja-kr8ul]

Excellent video sir, i could understand this as small level.

[@kyzercube]

Nature is not " fine tuned for life ". Life is fine tuned to nature. I find it disturbing when people in self indulgent folly and blind arrogance make such claims as this, especially when their ironic claims in which the opposite can be debated with ease. Almost as if such claims are being plagiarized or hijacked.

[@yziib3578]

You clearly do not understand fine tuning but you will state your strong opinion about it. Are you projecting blind arrogance?

[@musicodeon]

Great job explaining such an esoteric idea.

[@davidmixon7379]

Yes, easy to follow. Very clear. It occured to be to check out those numbers numerologically. I found that 137 reduces to 11 . If you can find a good numberologist with a track record ask him if 137 when it reduces to 11 has it become a master number. Also the 137 with .035 ect. reduces to 9

[@johndef5075]

Doesnt 11 reduce to 2?

[@davidmixon7379]

Thats true, its also true that 11 is a master number

[@jumperpoint]

Fine tuned for life is subjective. Since we are alive we exist in a universe where life is possible. We knew that before we had science. And having science there's no reason to believe that earth is the only place life is possible. So if the fine structure constant is required to create the conditions for life it's not a coincidence, it's a constraint. But it doesn't prove the universe is unique, or planned, or anything metaphysical.

[@roqueceravolo1969]

It was the best explanation on this excellent subject.

[@wulphstein]

There is zero likelihood that anyone on Earth will fall into a black hole (no matter how much physicists obsess about them). But there does seem to be a 100% that we are all sliding, ever so gently, back to God. Does anyone else notice that?

[@birefringent2851]

This is an awesome video but just one thing - under renormalization, alpha flows to zero logarithmically in the infrared due to its beta function being proportional to alpha^2. It's only approximately 1/137 at the intermediate energy scales of current experiments but if you could go to lower energies, you would see it going very, very slowly to zero as the electromagnetic force gets more and more screened from vacuum fluctuations.

[@robertw1871]

It just shows that our current theories are incomplete. Nothing more. That the electron is viewed as a probability is the first clue that something isn’t correct, and that nature does things nearly instantly that requires infinite calculations to approximate. We really need something more than mathematics to describe the abstract nature of the methods.
