But if you are holding hands then r² becomes zero and the force of attraction is infinite.
We can't all be astronauts.

Take the center of mass at that point. Can’t be 0 because atoms have widths.

If clothing can have 00 sizes then so can anything.

Yup. As I said in another comment, you are not a point mass. The amount of your and her flesh that’s atom-width close is an astronomically small fraction of the total weight, no matter how close you cuddle, and this fraction gets squared because there are 2 bodies. (It’s an integral over two volumes – in layman’s terms, an atom in your hand feels strong (for an atom) attraction to an atom on her hand, but not her head even if your heads also touch.)

Well we need to dive in quantum physics if we are going that deep, no?

r=2m, not 1m?

there’s an Avatar: The Last Airbender joke somewhere here, but i haven’t seen the show in some time and don’t remember what the joke is about

An r of 1.3mm or less will make it so you are more attractive than the moon!

You are not a point mass. The amount of your and her flesh that’s this close is a miniscule fraction of the total weight, no matter how close you cuddle, and this fraction gets squared because there are 2 bodies. (It’s an integral over two volumes – in layman’s terms, an atom in your hand feels strong (for an atom) attraction to an atom on her hand, but not her head even if your heads also touch.)

In other words, if you’re really deep inside her, her attraction to you will be stronger than to the moon.
Giggity 😏

I learned three things in physics:
- You can’t push a rope
B) Cows can be assumed to be spherical
III) Everything exists as a point mass. The Earth is a point mass, electrons are point masses, the aforementioned spherical cows are point masses…

Don’t italicize units and constants.
sga@piefed.social 12 hours ago
they kinda are not. it is most likely typeset in latex, where in equation mode all letters by default get italicised. and it is kinda accpeted as appropriate typesetting.
ChaoticNeutralCzech@feddit.org 11 hours ago
Well, it’s not appropriate typesseting. Unlike unknowns and constants (𝑥, 𝑐), units need to be manually unitalicized. In DOCX, this also prevents wide kerning (which is OK for several multiplied constants/unknowns but not multi-letter units). I only use serif italics for liter (𝑙), and only outside equations (it’s not SI base anyway), because I think a simple “l” can be confused with “I” or “1” while the alternatives (L, ℓ) look terrible in typesetting.

Try to be between her and the moon. Both your attractions will act in somewhat the same direction. Or at least F^→^~moon~ • F^→^~me~ > 0
