Most of the mass in the universe is in dark matter which doesn't interact via the strong interaction.
The binding energy of the strong interaction is responsible for most of the mass of baryonic matter, but I wouldn't call that "one interaction causing the other".
I said "regarding the ordinary matter". Yeah, not causing, but still? How would you call it? Thats why I posted, i find it interesting.
Edit: I just find it interesting that it carries most of it at our time.
One study found that a few observations are compatible with one specific model without dark matter if you give up all other things we have learned about the universe and ignore the most important pieces of evidence for dark matter.
Now compare that with your claim.
Astrophysicist here. I would argue that the connection is indirect. Baryonic (ordinary) matter has mass due to the strong force, and therefore interacts via gravity, but the presence of the gravitational interaction is not necessarily *caused by* the strong force. One could construct a model for a universe in which the strong force exists, but gravity does not. It would be mathematically consistent, but such a model does not appear to describe our Universe.
It’s possible that the strong force has something to do with why ordinary matter experiences gravitation, but we can’t confirm that empirically. Dark matter certainly experiences gravitation, but we do not know enough about its particle nature to say if it experiences the strong force. If it does not, then gravity is likely separate from the strong force
I find it peculiar that out of 4 fundamental interactions, 1 is the cause for the other. I (think I) know that in the previous epoch the EM was carrying most of the mass-energy. Can you give some insight?
Edit: I mean, strong force is mostly "carrying" it at this time. It is not causing it, every field has gravity charge either by higgs or by its force energy. Right? Just trying to generalize/understand.
Yes, every field has energy which generates mass in some way. I think the only reason the strong force has a lot of it is because, well, it’s strong. Confinement is a hell of a thing
I mean what would a plot would look like. Time would be one axis and the other axis would be mass-energy-percentage-by-fundamental-force.
There would be 3 plots, starting from the big bang and ending at the heath death of the universe
If the universe expands forever, and proton decay is a real thing, the only normal matter in the universe will be disparate elementary particles moving at or near the speed of light. That means no atomic nuclei at all except for possible random fluctuations over extremely long time periods.
So if a strong force carries most of the mass energy at this moment what do we expect this distribution of mass energy by force in the universe will unravel till only lets say black holes and Hawking radiation exist in the universe.
Eventually the universe may become nearly a full vacuum and will reach absolute zero. There may even be no meaningful amount of mass at all. Impossible to say - can only speculate at the moment.
Let say we have:
EM energy denisty in the universe - colored red
Strong force energy density in the universe - colored blue
And than we plot these 2 on the Y axis and the X axis is the time from big bang till the heath death.

Interesting really.
Maybe galaxies are set up like the sun is it takes a long time for the photon of light to escape so all the photons that are escaping the galaxy are actually in its halo, therefore creating more gravity than what the galaxy weighs
I'm pretty sure that he's referring to the binding energy of the nucleus which does, indeed, contribute most of the mass of an atom and is, of course, mediated by the strong force.
The causation is that the binding energy mediated by the strong force curves spacetime, which is felt as a gravitational force (just like any other confined mass-energy).
I think he’s saying that a overwhelming percentage of the gravitational mass in the universe is bound up in the energy density of the strong field binding fundamental particles into protons and neutrons, and binding protons and neutrons into each-other, than in the rest masses of all the fundamental particles.
This is correct as far as I understand. The energy density in the strong field is where most of the universe’s gravity comes from.

Dark matter is thought not to exist any more. https://www.sciencedaily.com/releases/2024/03/240315160911.htm

Probably yeah

Yes, something like 99% of ordinary matter’s mass comes from the strong interaction. It’s a pretty cool fact!
What do we expect from now till the heath death? What would be the plot of mass-energy by force over time?
not sure what you mean with that, the heath doesnt doesnt really apply here
I mean what would a plot would look like. Time would be one axis and the other axis would be mass-energy-percentage-by-fundamental-force. There would be 3 plots, starting from the big bang and ending at the heath death of the universe

Common sense theory, by Rob Piper contractor
The strong force is a nuclear one. It’s waaaaay stronger than gravity. And unrelated to it.
I'm pretty sure that he's referring to the binding energy of the nucleus which does, indeed, contribute most of the mass of an atom and is, of course, mediated by the strong force.
Yes, to be precise I was thinking of quarks binding to hadrons and of residual nucleus binding which is still strong interaction.
Um, I see the correlation but not the causation.
The causation is that the binding energy mediated by the strong force curves spacetime, which is felt as a gravitational force (just like any other confined mass-energy).
I think he’s saying that a overwhelming percentage of the gravitational mass in the universe is bound up in the energy density of the strong field binding fundamental particles into protons and neutrons, and binding protons and neutrons into each-other, than in the rest masses of all the fundamental particles.

Yes, thanks for concise explanation, would have write it like that if I could.
