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."

Watching this video made me feel like I learned something without actually having to have learned anything. Well done.
@zaddyjacquescormery6613
This might be my favorite episode of SpaceTime. Well done.

i can attest: it's amazing how i always understand almost exactly 1/137th of every PBS spacetime video i watch
@emergentform1188
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 found a u-lock in seattle. the locksmith was able to make a key. the number on the key is 137. i have thought of this number and see it as i move around. i decided, because of this amazing video, to see if there is an attraction correlation to the number and place.
@MichaelNiles
Little known fact: our universe was a typo, the 4D experimentalists had originally meant to type "1337" for the seed phrase

You don’t mention that using QFT you can show that the anomalous magnetic moment g-2 is alpha / pi to first order (which blows my mind)
@felixu95
Excellent video, but I think the number most universally stressed out over by physicists is the rent.

This is going to turn out to be something simple yet so out there that no one would believe it, such as it's just a built-in counter for the current iteration of the universe.
@kirksneckchop7873
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.

Ooooh, so that’s why R&M live in reality c-137 (spotted the ref to that too😅)
@jlewisstockett
These videos manage to blow my mind even though I only understand about 1/137 of the physics.
@MrJonhirt
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!

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.
@onlythetruthwillsetyoufree8872
I like the number 137.035999 better. Much more esthetically pleasing!
@mauriciofurlan7773
Parabéns pela excelente palestra da constante de estrutura fina. Ótima didática e clareza. Foi muito bom. Gostei muito!

What if there is intelligent life on the electron level or other places where 137 comes up trying to communicate to alien life somewhere else that they are intelligent by 'sending out' 137. Question is: Who started using 137 and why?
@Greatamericaneclipse
Outstanding and stimulating video! When I studied physics at UC Berkeley, my quantum mechanics classes were Physics 137A and 137B, not a coincidence
@lefthandedscrewdriver3954
This is way over my head, but none the less, very interesting. Great video.
