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

Shouldn’t gravity be like a tiny, vaguely dragon-shaped worm off in another field?

I mean messing with the strong force in a fistful of atoms gets you a nuclear bomb. Meanwhile, my old, achy self can jump up and resist against a whole earth’s worth of gravitational force.

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.

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.
