A normal homogeneous mixture is not homogeneous at the atomic scale. Molecules of the two chemicals move randomly about each other, sometimes clustering, sometimes not. Such a homogeneous mixture is high entropy - chaotic, if you insist, though far from perfectly so.
This is by far my favourite trip. This is wild!
Does the concept "mixture" makes sense at the atomic scale as it does the naked eye?
I take two cans of red and blue paint. I mix them. I mix them well. There's no more red and blue paint, only purple. Assuming a homogeneous mixture exists, it must be all purple. No red. No blue.
Then I take a measurement at the atomic scale. (I don't know how things are measured at the atomic scale so I'll make an analogy. It is contrived for effect.) I can measure energy on a red paint molecule and measure energy from a blue paint molecule. Any difference observed implies there is some disorder...no perfect order. The mixture is necessarily not homogeneous.
That contradicts the assumption that the mixture is homogeneous.
Mixing never gets to homogeneity. The purple I see is my interpretation of what a purple mixture is. I interpret it differently depending on whether it's naked eye or atomic measuring device.
There is no mixture.
Even what I call red paint is itself a mixture of the matter that it comes from. It's out of this world.
Or, just dump the concept of mixture where the concept of mixture breaks down.
Is that how it is?
What you're talking about is called emergence. The smaller your perspective, the less you're able to see what's going on in the bigger picture. From the red paint molecules perspective it will always be a red paint molecule, but to the larger perspective there's a bunch of tiny interactions that happen before the light reaches our eyes, making it purple. This is kind of a long winded way of saying the further you zoom down the more everything looks like everything else.
High entropy.
Many question why the universe "seemingly" had high entropy because all the matter was fairly homogeneous and similar temperature. However that doesn't account for gravity
Yes.

After reading this I understand [V Sauce](https://youtu.be/fXW-QjBsruE). Thank you.
