Electroweak Theory and the Origin of the Fundamental Forces

Our universe seems pretty complicated. We have a weird zoo of elementary particles, which interact through very different fundamental forces. But some extremely subtle clues in nature have led us to believe that the forces of nature were once unified, ruled by a single, grand symmetry. But how does one force separate into multiple? And how do the forces of nature arise from mathematical symmetries in the first place?

“Our universe seems pretty complicated” Understatement of the year, Matt.
-
This is the first episode in a long time where I really didn’t understand much of anything. My head hurts
-
I can't even imagine how satisfying it must have been when this theory got proved at CERN.
-
This was definitely one of the harder to understand videos you've done. But I respect that the subject of the electro-weak force is just complicated, so I appreciate the explanation all the same.
-
Spacetime is so good it makes me feel like I understand things that I DEFINITELY do not understand.
-
I love being walked carefully through Feynman diagrams. For a moment I think "I understood that" but then I realize a moment later, "Nope, I got nothing."
-
Hey matt! Just want to say I appreciate you and the whole SpaceTime team! You guys are by far my favourite YouTube channel!
-
Matt's t-shirt is violating symmetry :(
-
The outro to every video having, usually a run-on sentence, an extended play on words to bulk it all back into a thematically relevant and compressed summary of the video inevitably bounding it all back in to the everything-ness of.... Spacetime; it always gets me! Every single time! I love it! ^.^
-
"Not very satisfying" is EXACTLY how I've always felt about the radioactive decay definition of the weak force!!
-
“Specialist Relativity” Good one 👍
-
I would LOOOOVEEE a follow-up video on this subject!! As a non-physicist, I have been DESPERATE to understand symmetry breaking, gauge field theory and special unitary groups. This video did more for me than any book I've ready so far but still left me with more questions than answers (as it should!)
-
"The midichlorian" lmao I love you, Matt
-
My brain definitely melted on this one
-
So, if you heated a region of space above 10^15K, could you get the Electroweak force to break symmetry in a different way? Like how heating and cooling the bar magnets can lead to the group pointing in a different direction.
-
The example of spontanious symmetry breaking of a magnetic field at the Curie temperature is brilliant.
-
This one was definitely worth waiting till the end. I was a bit confused for a while but it came together beautifully in the end! Great vid!
-
The entire time watching this I was just waiting to hear Grant Sanderson's (3blue 1brown) voice explaining some of the math. To think of it, it would be cool to have him on as a guest once...
-
If we have 4 forces that used to be less, how outlandish is it to assume that the forces we currently have can be further broken? Do we have proof that they're 'prime' forces?
-
The irony of Matt's shirt neck while talking about symmetry 😅
