4 fundamental forces

  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.

    Au contraire, mon frere.

      That, and have you seen the amount of propellant required to overcome gravity? Compare that to the amount of fissile material you need to make a viable nuclear device. It’s peanuts.

      You inadvertently argued against your point. It takes only a tiny amount of fissile material to generate the energy needed to escape the gravitation of an entire planet.

      But not really because you only compared chemical energy to fission.

      I was more just speaking to how it’s many orders of magnitude weaker than the other 3 forces. Though it does work on an infinite scale, so maybe it ought to be a tiny bit unbelievably long vaguely dragon-shaped worm thing.

    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 because the renormalization constant is not a constant.

      Yup got it. In that context mega-dragon makes sense. I can’t wait until we actually understand what the hell gravity even is.

      Some physicists have suggested combining the EM and weak forces because of the interplay between them.

    While that is true, for how long can you resist gravity? Gravity is the endurance hunter of the fundamental forces. Sure, you can lift your arm and resist the entire earth’s gravity. But for how long, before you succumb to gravity’s irresistible pull?

    • Swedneck@discuss.tchncs.de ⁨3⁩ ⁨weeks⁩ ago

      resisting gravity is super easy, as evidenced by the fact that most things aren’t black holes.

    You didn’t really overcome it though. After 2 seconds you got pulled right back.

      Yup. But try pulling a proton out of an atom for 2 seconds.

  Gravity should be the derpy looking one.

    Yeah, definitely. Don’t know why the literal weakest force in the universe is depicted as some mega dragon.

    source

    • sga@lemmings.world ⁨3⁩ ⁨weeks⁩ ago

      maybe it is because being so weak, it allows things to be come together, and eventually be strong enough, by power of family.

    Are you kidding? The strong force depends on colours and increases with the distance, how is it not the derpy one?

    Look man, the more I hear this argument the more I want to get into a Ph D program to figure out a better way to describe how fucking weird the Strong force is.

    Sure, it “increases with distance” but the amount of energy you put in separating two particles bound by the strong force increases the probability of creating a new particle from the vacuum and then that distance snaps instantly. It has a practical limit if it is within the bounds of spacetime.

    I mean, increasing with distance isn’t that bad, since it only increases upto a point and goes out of range.

    I like that its analogous with springs and all, which also increases force with distance from mean position

    What do you mean by color?

    source

    • mexicancartel@lemmy.dbzer0.com ⁨3⁩ ⁨weeks⁩ ago

      “Colour charge”, ehich has nothing to do with colors though. Its like electric charge but instead of two opposite(called posotive and negative), it hace three “colours” which obeys R+G+B=colourless(white) just lije positive+negative equal zero

  It’s a matter of scale, but gravity is often considered the weakest force. In quantum physics, it’s so weak it’s often impossible to measure.

    it’s not about the strength it’s about the complexity of the theory
