Yup got it. In that context mega-dragon makes sense. I can’t wait until we actually understand what the hell gravity even is.
Comment on 4 fundamental forces
stebo02@lemmy.dbzer0.com 3 weeks agoIt’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.

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 because the renormalization constant is not a constant.
