Made this meme while studying CP violation in weak interactions… weak force why cant you be normal?? :cry:

It’s not a meme about the strength but about how complex the physics are.
The weak interaction breaks a lot of symmetries that hold in EM and strong interactions, like CP symmetry. Its gauge symmetry is also completely wild: SU(2)L x U(1)Y, compared to U(1) for EM and SU(3) for the strong interaction. And finally there’s also neutrino oscillations related to that. So to me the weak interaction is like a derpy brother to the other two.
Then gravity is something completely different and we are yet to figure out how to describe it in quantum physics. So that’s why I chose that creature.
The weak interaction is just electromagnetism if the photons had mass and charge (and broke CP and flavour simmetry, yeah). Above the unification scale they are literally the same field.
Plus, what really makes a theory hard is how hard it is to compute a prediction. There electroweak group is renormalizable. For the strong force you need to do weird lattice calculations.
I maintain that the strong force should be the derpy one.
I love that we’re this far along in physics and the question of “what even is gravity anyway?” Is still fundamentally unsolved.
My favourite theory that I’ve seen so far is “entropy increases, and black holes have maximum entropy of anything in the universe, so everything is always trying to become a black hole.” Stuff falls downward just because that’s the easiest and most immediate way of making progress towards being a black hole.
Obviously, this is a layman’s understanding.
Interesting theory. On the other hand, if everything would diverge instead, like with the expansion of the universe, we also reach maximum entropy. So why wouldn’t gravity be repellent?
My understanding is it’s because black holes are the way to maximum entropy. Widely dispersed material has lots of potential energy and lots of possible states, but black holes are “the end” - there’s no further change possible once you get there. There is no state of matter or spacetime with more entropy than that.
Ohh that makes quite a lot of sense. I always imagined entropy increase as more things are spread out, but i never considered gravity so turns out I was assuming repulsive(electromagnetic) forces when talking about entropy because we usually always considers a system of molecules
Yup got it. In that context mega-dragon makes sense. I can’t wait until we actually understand what the hell gravity even is.
What is CP?

Some physicists have suggested combining the EM and weak forces because of the interplay between them.
You’re talking about electroweak unification. They’re unified because the force carriers of the weak interactions are charged bosons, which implies they also interact electromagnetically. Therefore you can’t physically describe the weak force without including electromagnetism. However these two forces are still fundamentally different.
