Gravity is the weakest fundamental force, yes. At least, at relatively close distances. The advantage gravity has is that it never quite goes away, no matter how far you are.
So it’s like humans? 🤔
We aren’t particularly strong or fast, but we became apex predators because we never. Stop. Coming.
Also, we, never, stop, cumming.
So much to cum, so much to cum,
So what’s wrong with cumming the backstreet
You’ll never know if you don’t cum
You’ll never cum if you don’t blow
cum cum, cumcumcum cum, get ur cumcum CUM----CUM
AND ALL THAT’S CUMMING IS CUMMMM
only shooting cummmm breaks the mOwOld
(Smash mouth were so ahead of the curve, they had OwO in their lyrics in 1999)
Can you imagine being those antelope being hunted by early human ancestors -
“Ok, bob, we just bolted at 40mph for a minute or so, they’re not going to find us again.”
“Clarice, you said that the last 8 times and they still showed up! They’re unnatural! They just keep following and following us! Alex smashed his shin that last run, and I don’t know how many more times I can run myself! We’re doomed Clarice! Doomed!”
It’s basically a zombie movie, but the main character is Bambi.
They cannot be bargained with. They cannot be reasoned with. They don’t feel pity, or remorse, or fear. And they absolutely will not stop. Ever. Until you are dead.
about to make ourselves go away though.
Whoops
Whoopsee
Exactly. Raise your hand. Great, you overcame gravity for a second. Keep your hand raised for a minute. 10 minutes. An hour. Fuck, gravity doesn’t stop. It’s exactly like us.
I mean yeah but also you reverse that square enough and it’s effectively zero
But never actually zero, unlike those other quitter “forces”
Is that actually true? I’m not an expert but I thought all forces extend our into infinity. I thought we just allowed them to go to 0 at a certain radius for the sake of making the math manageable.
Not the person you replied to, and not really an expert either, but I can tell you that the W and Z bosons (force carriers for the weak force) are very short lived and can only travel through space so far before they decay. This effectively puts a cap on the distance of weak interactions.
Strong force is the same.
I don’t know if it’s shorter than the weak force, but you gotta be in an atom’s nucleus to experience it
Edit: i just realized I may have confused people - strong force has a limited distance, not that it’s because they decay.
Edit 2: If i ever got a PhD or master’s even in Physics, id probably write a book on how “The Universe Demands Laziness.” Because pretty much everything in physics ends up with a system taking shortcuts to save a little bit of energy.

This is how I teach both physics and chemistry. Electrons are lazy - they’re going to chill in the lowest energy level they can. They fill in sub shells like people getting on a bus - you aren’t going to sit next to someone else unless you have to, you’re going to sit probably as close to the front (nucleus) as you can.

That’s what she said.
The strong force also gets stronger with distance
Except the energy required to increase the distance between the particles is enough that it ends up creating more particles and the distance never gets any more distancier?
So this is where my inexperience kicks in, but I don’t understand how the strong force can function in the same way considering that gluons are massless.
The W and Z bosons having mass prevents them from being able to travel at the speed of light, and therefore they experience time and can only travel some limited distance before decaying into fermions.
But since gluons do not have mass, they, like photons, do not experience time – and so how could they have a half life?
In my mental model of the strong force I assumed that they simply were created and destroyed in an exchange between quarks – much like how photons get absorbed/emitted by electrons. But this alone does not cause a limit on the distance of strong interactions, so I assumed that mechanically any limit on the strong force’s distance must function differently.
Gluons do not have a half life?
Remember that they DO make an exchange - Gluons have color charge - red, green and blue. QCD is the magical realm of color charge.
The hardest part for quantum anything is grasping the “probability aspect” means spontaneous things can happen. In the case of QCD, as you put energy into separating quarks it becomes infinitely more likely to pull particles out of the vacuum than to separate them.
QCD is involved in fusion in a similar way - two protons will oppose each other with infinitely more force the closer they get because their charges are repulsive. The faster two protons are flung at eachother, the probability of the quarks binding increases.
TIL the Univers was written in Haskell
Ostensibly sure but really it’s all hacked together perl
Nah, at some point the simulation we live in is going to round down to save computing power.
Is that simulation in the room with us ri

The advantage gravity has is that it never quite goes away, no matter how far you are.
That’s true of all the fundamental forces, though. They all drop off over distance with inverse square laws. Like if you had two lone electrons in an otherwise empty universe, their electromagnetic repulsion would also persist indefinitely at 1/r^2 strength, just like gravity. The difference is that our universe has near-perfect charge neutrality at large scales.
Electromagnetic doesn’t go away either. It’s that damn negavite charge neutralizing the stuff.
Aren’t all forces subject to the inverse square law?
Dipoles are, effectively, not — so if you have a charged bit and another opposite charged bit, while an inverse relationship might exist between either one, the net effect is that it drops off much faster.
The thing with gravity is it tends to go one way, unlike, say, charge.
Sounds like a stalker.
Gravity’s so powerful, it’s letting you win this round just to remind you who’s really in charge when you drop your phone
Say that to gravity when you start even 5m above the ground.
Gravity ain’t shit. It’s not the falling that kills you, it’s the impact at the bottom. Which are electromagnetic forces.
Are you enjoying your Kep-mok blood ticks, Dr. Lazarus?
Well the electromagnetic forces in your bones are no match for the accumulated energy of a few seconds of gravity.
The thing is, you need an entire planet to make falling hurt, and jumping is still easy. Meanwhile, if you have two tiny magnets they can pull on each other so strongly that you can never get them apart again.
Yeah, go ahead, how long can you keep it up? The earth can wait longer than you.
Challenge acceptedJust lost faith in my muscles
There goes all our bragging about humanity’s physical superpower being endurance.
Now keep this hand raised for an hour. Who’s the bitch now ?
If it takes your an hour to wear me down, you’re weak. No matter how inexhaustible your power is.
How about 10 minutes ? World record is 9.

India is in it’s own timeline.
ex. Indian breatharian monk who claimed to have lived without food and water since 1940.
https://en.wikipedia.org/wiki/Prahlad_JaniBut there is a difference between making a claim about not drinking water and literally holding your hand up in a way you can’t fake.
Yeah he was obviously sleeping for 50 years and holding his hand up. I can believe that.
Look at his arm. Unless all the videos of that guy are fake (even during a time where making a convincing video fakes was really hard). That arm is not going down even if he wanted.
Unintentionally hilarious link
Oh don’t worry, it will be way less than an hour :P
Lower strength, but far more endurance.
Does gravity do work or is it just reactive? If it doesn’t do work, doesn’t it match endurance exactly to you?
Weak you say?.. See those merging black holes? Proceeds to casually dissapear 3 solar masses in less than a second… Yeah.
Which is still just a small fraction of the total mass of the black holes
If it were the electromagnetic force that pulled them together it would be so much more violent and send out deadly gamma rays
But that will never happen, because electromagnetic forces haven’t learned the power of friendship and co-operation. Gravity always works together, but the other fickle fundamental forces just can’t decide if they are pushing or pulling or whatever.
yeah you’d need a black hole where every atom is positively charged and one where every atom is negatively charged
and whose fault is that? i’m look at you, horses
I just overcame the gravitational pull of the entire planet with my dick.
If your dick overcomes the gravitational pull of the entire planet for more than four hours, seek medical attention
username checks out
Referring to your girlfriend that way is not very nice.
Your dick also overcame the gravitational pull of all other dicks.
You didn’t overcome it, you spend some energy that the earth will eventually get back.
Unless you leave earth, gravity will eventually win.
The house always wins.
Can’t even win then. Gravity isn’t just on earth. It’s a universal force.
They are launching objects to space accidentally, doing it intentionally cant be that hard
Nobody trips, falls, and detonates a nuke.
People try to hide obvious mistakes they make. Nobody is going to go on a stage and scream “I ACCIDENTALLY DETONATED A NUKE”
And you wouldn’t download a nuke.
Clearly the tripwires in your basement aren’t hooked up to traps nearly as fun as they could be.
If you’re hot enough and place a mirror below you blackbody radiation should do a pretty good job at preventing that. If you’re not that hot you might need extra patience and without the mirror it might not be too effective.
Now that I think about it this might be considered as parts of oneself leaving earth though.
This unlocked a song that has been buried in my mind for YEARS:
Now some of you may think that gravity is strong Cuz when you fall Off your bicycle It don’t take long Until you hit the earth And you say, “Dang that hurt!”
But if you think the force Is powerful You’re wrong
You see, gravity It’s weaker than weak!
And the reason why Is something many Scientists seek
They think about dimensions We live in just three But maybe there are others That are too small to see
It’s into these dimensions that gravity extends Which makes it seem weaker here on our end
And these dimensions are rolled up, curled so tight That they don’t affect you in your day-to-day life
But if you were as tiny as a graviton You could enter these dimensions and go wandering on And they’d find you…
LHCb sees where the antimatter’s gone, ALICE looks at collisions of lead ions
Oh, a song from the time superstrings were still cool?
A brave little theory, and actually quite coherent for a system of five or seven dimensions — if only we lived in one.
Yes, it’s the obvious extension from what we have now, and quite coherent for explaining some universe that isn’t the one we live in.
It just shouldn’t have monopolized theoretical physics for a generation. It’s really hard to imagine something different, but this is even more reason to celebrate the people trying that, not to shun then and focus on what you already have.
Wasn’t this in Particle Fever? That doc is incredible.
“Gravity is weaker than weak” is such a strong line.
Did he just tough-talk the curvature of space-time?
thats just because the gravitational pull of your hand is weak shit.
Get more mass, massless nerd.
In a system where gravity is pulling on your hand, which is stronger, the force of the earth pulling in your hand, or the force of your hand pulling on the Earth?
Answer: it’s a trick question. In such a system, both sides feel the force equally
if we’re talking gravity physics, the earth, by basically every possible kilogram of mass imaginable to the human mind. But this goes without saying, because you stick to the earth, the earth doesn’t stick to you, so.
Of course technically, the force is applied to both objects, but considering the scale mismatch, one of these things is not like the other.
No you’re both drawn to the local center of gravity which is on a direct line between both bodies’ centers of mass and is proportionally closer to the object of higher mass.
That’s not really relevant in collided objects per se, but it means you and the earth both pull each other equally to a point that happens to be located ever so slightly away from the center of the earth. Well you would if there weren’t a ton of other gravitational influences including the non uniform shape and density of the earth that make you basically rounding error in terms of gravitational force. But you do impact it
And now jump in the air and escape the gravitational pull.
12 kilometers straight up.
- 150 km.
Gravity not so weak now, huh?
It’s still weak, just like humans are still slow.
At least compared to other animals.
But like gravity, we just keep going. And going. And going.
And when the animals we hunted collapsed from exhaustion, we just kept coming. And then took it all the way back we came.
Just like gravity.
We can try to keep going until we just can’t anymore, but gravity will just grab us and haul us back.
Compared to the other forces, gravity is a weak ass bitch.
deleted by creator
Also not so weak if you find yourself at a height in the air.
And still it is powerful enough to completely close off parts of the universe from the rest. Truly fascinating.
Back issues are Gravity’s revenge.
Yeah but ain’t no motherfucker gonna soon be jumping over onto the moon with pure human leg power. Still gotta detonate a slowly exploding bomb under our asses to leave this rock-covered ball bearing.
