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

Are you kidding? The strong force depends on colours and increases with the distance, how is it not the derpy one?
The weak interaction is just electromagnetism if the photons had mass (and broke CP and flavour simmetry, yeah).
Color is just a word for a quantum property, not actual color.
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
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.
Edit: sorry I hit save before I finished
So not only is it special strong, if we define it with the only known things we can define anything with, it breaks all sorts of other things. And since the entire universe isn’t bound together into one tight strongly held particle possibly means that the only reason the universe exists at all is because defining the strong force forced particles out of nothing.
Please do! Us physics enthusiasts laymen need ANSWERS ! :D
What do you mean by color?
“Colour charge”, which 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
There are still opposite charges - each colour has an ‘anti’-colour. So R+
R=colourless G+G=colourless etc. This is how mesons work (pairs of quarks). Baryons are triplets of quarks but there are also combined tetra- and pentaquark states also.You can think of anti-red as being cyan etc. but the colour theory can be more confusing than it’s worth.
Yeah but aren’t they the antimatter version of thoose colour charges? Didn’t mention it for that reason but yeah mesons
fair point, but at least it doesnt break so many symmetries
strong is like the cool hippie brother
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.
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?
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.
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.
Au contraire, mon frere. “Sir Isaac Newton is the deadliest son-of-a-bitch in space.”
if you have enough mass moving quickly enough, someone’s gonna have a real bad day. Gravity is fantastic for getting a lot of mass moving very quickly, it’s why space missions slingshot around planets to get from A to B instead of burning propellant straight there. Even dropping tungsten rods from orbit can get you atom-bomb-sized explosions, and if you had any means of (even weakly) accelerating them before that, gravity would help further accelerate them.
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. A (small) nuke might as well be a rounding error compared to the amount of fuel you need to overcome gravity and leave earths orbit, gravity is that much of a fuck.

You inadvertently argued against your point. It takes only a few kilograms of fissile material to generate the energy needed to escape the gravitation of the 6 billion trillion kilograms gravity of earth.
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. My point was not that combustion-based propellants are energy efficient, merely that it takes a lot of energy to escape gravity, and while theoretically nuclear propulsion would be more efficient, in practice, burning shit is really the best we can do without giving someone cancer every time we want to put something in orbit, because gravity is a fuck.
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 but unbelievably long vaguely dragon-shaped worm thing.
Upvoted for Mass Effect, my beloved.
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.
Not recommended
I can pull a Proton out and put it back in, as long as you’re not observing me
lol that sounds like a toddler saying “mom I can fly but i can only do it if you look away”
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.
And then you look away from it for a couple billion years and it combined with with all of its friends into the devourer of worlds
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.
maybe it is because being so weak, it allows things to be come together, and eventually be strong enough, by power of family.
Then it should be Vin Diesel…
🤌
Gravity bends the geometry of spacetime itself, it’s pretty eldritch to me.
I explained my reasoning here:
Gravity at human scales: I sleep
Gravity at stellar scales: Real shit
The strong force has colored charges and increases with the distance, how is it not the derpy one?
The weak interaction is just electromagnetism if the photons had mass (and broke CP and flavour simmetry, yeah).
The weak force is super cool actually
it has its charms
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.
Weakest force but with the longest range right?
I don’t know about Gravity being the derpy one, but it sure is the most annoying AF. Stuff keeps falling off the nightlamp when I reach for it, or I have to retrieve something moderately heavy from the back of the top shelf and it ends being a hazard to health.
Nah… F#*k gravity.
just be glad that the planet is neutrally charged because otherwise you’d be toothpaste
Planet is negatively charged. That’s how lightning and spiders work.

well i meant every atom in the entire planet
CP violation in weak interactions
Weak force, why don’t you have a seat over there
Gravity is actually a weak force.
it’s not about the strength it’s about the complexity of the theory
That was definitely not clear.
sorry
