What’s the other 4? Gravity… and… Light? Kinetic? Magnetic?

[–] 133arc585@lemmy.ml 36 points 1 year ago (1 children)
  1. Strong nuclear force: holds the nucleus of an atom together
  2. Weak nuclear force: responsible for radioactive decay
  3. Electromagnetic force: of charged particles
  4. Gravitational force: attractive force between objects with mass

Not all decays are weak-based, though, and not all weak phenomina are directly related to radioactivity. That's just the only thing a layman has heard of where it's relevant.

The strong force only holds atoms together through a sort of trickle-down force, too, but that one feels like splitting hairs.

The person I replied to wasn't able to name the forces beyond gravity, so I think over-simplification and reduction to specific phenomena they would have heard of is appropriate.

Oh, absolutely. I was adding on for anyone else reading who might appreciate answer gravy. Sorry if it came across as critical of what you wrote, my bad.

[–] 133arc585@lemmy.ml 7 points 1 year ago (1 children)

Gotcha, no problem, I did take it as criticism of my comment but that was a reflex.

[–] CanadaPlus@lemmy.sdf.org 2 points 1 year ago* (last edited 1 year ago)

Reading it back I don't blame you. It does come across as an attempt to argue.

Gravity, The weak force, Electromagnetic force, The strong nuclear force

They're literally listed in the article

[–] Knusper@feddit.de 4 points 1 year ago

Well, the article currently lists them as: gravity, electromagnetism, the strong force and the weak force.

If you're not familiar, you wouldn't be able to guess that the last two are nuclear forces and in the context of a new force, that list is rather confusing.

[–] cwade12c@lemmy.world 2 points 1 year ago

The body of the article lists them, they just aren’t listed in the title.

If I remember there's weak and strong nuclear force, then two others.

[–] SpaceNoodle@lemmy.world 0 points 1 year ago (1 children)

No, there's two others, then the nuclear forces

[–] sanguinepar@lemmy.world 1 points 1 year ago (1 children)

I think there's a nuclear force, then two others, then another nuclear force. But I could be wrong.

[–] SpaceNoodle@lemmy.world 2 points 1 year ago (2 children)

Maybe it's nuclear forces all the way down

[–] sanguinepar@lemmy.world 2 points 1 year ago

Yes, but the real nuclear forces were the friends we made along the way.

Someone’s trying to connect the dots on a grand unified theory.

The best ones are all untestable.
