  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.

      Yeah, but we have no useful way to channel the energy from nuclear fission into propulsion, so that’s a moot point if we’re talking in practical terms. At least, we don’t without irradiating everything.

        You can do nuclear without irradiating everything just like a nuclear plant doesn’t irradiate everything. The only reason it isn’t done is safety. Rockets fail too often.

        The argument that gravity is in anyway a more powerful force than weak force (fission) or strong force (fusion) is wrong. The only thing gravity has is distance. The strong force is 100 trillion trillion trillion times stronger than gravity.

    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.

    What is CP?

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

    source

    • stebo02@lemmy.dbzer0.com ⁨2⁩ ⁨days⁩ ago

      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.

  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 ⁨1⁩ ⁨day⁩ 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.

  • will_a113@lemm.ee ⁨2⁩ ⁨days⁩ ago

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

      Not reccomended

        I can pull a Proton out and put it back in, as long as you’re not observing me

  idk, man. that gravitational sigularity over there would like to have a word with you.

  Close up off monstrous, horrifying, dangerous gravity dragon… pull back and back and back, and realize it was 1000x magnified. It’s magnificent roar a barely audible squeak.
