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.

That's what she said.
