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.
Electromagnetic doesn’t go away either. It’s that damn negavite charge neutralizing the stuff.
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.
Sounds like a stalker.
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.
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
Referring to your girlfriend that way is not very nice.
Your dick also overcame the gravitational pull of all other dicks.
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.
You didn’t overcome it, you spend some energy that the earth will eventually get back.
Unless you leave earth, gravity will eventually win.
They are launching objects to space accidentally, doing it intentionally cant be that hard
Can’t even win then. Gravity isn’t just on earth. It’s a universal force.
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.
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
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.
and whose fault is that? i’m look at you, horses
yeah you’d need a black hole where every atom is positively charged and one where every atom is negatively charged
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.
And now jump in the air and escape the gravitational pull.
12 kilometers straight up.
- 150 km.
Gravity not so weak now, huh?
Also not so weak if you find yourself at a height in the air.
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.

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
“Gravity is weaker than weak” is such a strong line.
Wasn’t this in Particle Fever? That doc is incredible.
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.
Overcome? The hand is clearly still under the effect of gravity as it is not flowing into the space. It just decelerates a tiny bit.
Back issues are Gravity’s revenge.
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.
Oh don’t worry, it will be way less than an hour :P
How about 10 minutes ? World record is 9.

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
True, however… as you press into this planet, this planet presses into you.
Then gravity reminds you who’s boss the next time you trip over your own feet
