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."

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

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, for one, appreciate his brief inclusion of the Weighted Companion Cube in his effort to explain an inexplicable circumstance.
Excellent video, but I think the number most universally stressed out over by physicists is the rent.

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

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.

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

Maybe we should try asking one of our bigtime AI brains this question, who knows, maybe the answer is obvious, just not obvious to humans.
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.

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

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!

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

so what if near the beginning of the universe other forms of life formed within the influence of a higher constant than we have now?

what if math isnt advanced enough to fully understand quantum mechanics or any other part of physics?

This is way over my head, but none the less, very interesting. Great video.
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
Poornakumar Das
I 've been worrying myself about this α, all these years. You have brought it out clearly.Thank you very much.
