"...so the *net* force that holds us together is just a tad less than it otherwise would be."
While I agree, I think "tad less" is an overestimation. It is barely measurable. It is 10^-14 times the force of gravity between the Earth and the moon. That is miniscule. There's probably more force from solar wind, other gravitational interactions, etc....
Atoms nuclear expanding and expanding nuclear opening expanding electrons and expanding photons who open also energywawes where is very small expanding particle and so on.
I can expalin everything with pressure
check it out my video
No Gravity
Idea from Kuopio is a video where i told how visible Universe really MOVES
Lets told that for your friend. You can doing history with everybody who told that for some other people.
One of the most fundamental principles of Physics is the conservation of mass/energy. This states that the amount of mass + energy in an isolated system remains constant. I'm afraid your theory is definitely wrong :(
I think you mean dark energy not dark matter. That's the picture that I've got, though its only speculation as nothing is known about the nature of dark energy.
tronreitan is right that "matter starts off by moving away from all other matter, with velocity proportional to the distance" even just after the big bang.
That could more be an explanation for individual galaxies. galaxy clusters tend to expand too, just slower than they would if they weren't a part of a cluster. Case is, there's no fixed size to a galaxy cluster. There are clusters of clusters and superclusters of those again.
This was something I studied on my master's degree. It turns out that you need a weakly hierarchical distribution, which can be glimpsed in the cosmological background radiation. This small inhomogeneities works on each others, so you get strong clustering on 'small' distances and weaker but still significant clustering on sizes up to 10% of the size of the observable universe.
Thanks. It surprised me, though it makes sense when explained. I'm trying to sort out how galaxy clusters end up moving away from each other - could it just be this phanthom anti-gravity force continually accelerating them for billions of years ?
Well I'm rusty with the cosmology stuff, but I would say that it's about initial conditions. The movement of matter and the space-time is linked together in General Relativity. What that means is that with and expanding universe, matter starts off by moving away from all other matter, with velocity proportional to the distance. The tricky bit is to describe the initial events in the Big Bang, such as inflations and the like.
In Stankus' video cosmology course he introduces the Freidmann equation which if I understand it, is a solution of GR which balances the pressure and gravity and determines the expansion. I'm way out of my depth here.
I've been thinking that this determines the size of galaxy clusters. Their gravitational attraction goes as 1/r^2 and the cosmic antigravity force is proportional to r. Where the forces cancel the clusters split apart.
this has nothing to do with expanding universe theory but it would be important to note that the moon is slowly drifting farther away from the earth due to tidal acceleration
He took a long time to explain something very simple:
We *are* being pulled apart (since --we believe-- we are in an *accelerating* universe) by an effective "phantom force," but the forces that hold us together are much stronger than that, so the *net* force that holds us together is just a tad less than it otherwise would be.
Probably similar to how you presumably become more bloated when the air pressure is lower.
He didn't say that we're being pulled apart - just that we are being pulled. We don't continually expand - we're static but slightly larger than we would be in a zero acceleration universe.

i doubt anyone would read anything beyond this horrible jumble of words.

Stankus explains that we're not expanding !
Even if we were expanding would we know about it ? If the wavelength of light also expanded then all our local measurements would be unchanged.

Interesting. The universe is always more complicated than we imagine.
BTW you might want to check out my little cosmology group (I've added some of your videos). I'll send you an invite.

Interesting video. As an ex-cosmology-student, I should have wondered about this when I studied, but I didn't. Very good that you posted it.

Noted. This is quite well understood and can be taken into account.
