    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.

    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."

    Whoa trippy. Love this channel and how it keeps telling me wild things I've never heard before, despite being relatively well versed in physics for a layperson.

    i can attest: it's amazing how i always understand almost exactly 1/137th of every PBS spacetime video i watch

    It occurred to me that this isn't the first universe.

    Excellent video, but I think the number most universally stressed out over by physicists is the rent.

    Great video and I thought you really meant the other number 1.618 which 137 degrees must relate to, surely? Only isn't that the degree of space apparently to the seeds of a sunflower as arranged by nature herself!? Only that I stand to be corrected as I'm not a first chemist starter, but couldn't that be the space molecularly for organic life in 3 branches of the visual spatial shape of the molecule with the key elements for essential life as we know it? I don't know, you tell me as I'm interested in using quantum mechanical processes in a colloidal solution electrolytic and I'm just using western liberal "think for yourself!" with London tap water as the ideal colloidal chemical solution to hand! Indeed, I know also we surely have the largest production of hydrogen electrolytic storage manufacturing for our green quantum fourth industrial revolution, don't we!? Also using what appears to be a diamagnetic pyrolytic carbon nanomaterial experiment, with an natural insurance policy included! Just that I hope we are not eating plastic hydrogen polymer derivatives with unintended carcinogenic effects of electromagnetic fields to boot, and surely not with so-called forever chemicals!? I hope I'm wrong of course, but I don't need to be a qualified scientist to know that would be the largest unsolicited experiment unconsented ever in human history, wouldn't it?

  • Michael Niles

    Little known fact: our universe was a typo, the 4D experimentalists had originally meant to type "1337" for the seed phrase

    I thought I found a video that had the answers to life. Instead I found a video about quantum physics that’s way over my head.

    And I thought 42 was the answer to the ultimate question of life, the universe, and everything.

    Watching this video made me feel like I learned something without actually having to have learned anything. Well done.

    So 137 only works in base 10?

    just finished reading QED and loved hearing all the references in this video. been enjoying the channel a lot. thank you for all your hard work!

  • Great American Eclipse

    Outstanding and stimulating video! When I studied physics at UC Berkeley, my quantum mechanics classes were Physics 137A and 137B, not a coincidence

    Why am I hearing about this number for the very first time in my life after years of watching various popular science videos like that? Odd it’s not talked about more.

    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.

    Hate to throw a wrench in the universal language of mathematics, but I highly suspect that 1/137 is an arbitrary abstract, and not a universal constant.

  • Mauricio Furlan

    Parabéns pela excelente palestra da constante de estrutura fina. Ótima didática e clareza. Foi muito bom. Gostei muito!

    These videos manage to blow my mind even though I only understand about 1/137 of the physics.

  • Poornakumar Das

    I 've been worrying myself about this α, all these years. You have brought it out clearly.Thank you very much.
