A hydrogen atom is defined by wave functions, so it is quantum matter. A dust grain is governed by classical interactions. So my question is how do you define the behavior of a molecular cloud? is it governed by quantum interactions and wave functions or classical? The issue is that there is a...

I'm looking for information on how the first dust grains came into existence, before stars existed.

Quantum matter that is described by the laws of quantum physics - aka wave functions. To contrast, think about classical matter, like a piece of dust. Although it is made up of quantum particles, it isn't governed by wave functions and doesn't exhibit behaviors like the uncertainty principle...

I do have specific questions and I have read this. In the Section Dark Ages - "Stars and galaxies are formed when dense regions of gas form due to the action of gravity, and this takes a long time within a near-uniform density of gas and on the scale required, so it is estimated that stars did...

I'm pretty sure it is a little more complicated than that. We'realing about early in the history of the cosmos, so things are hot, moving at great speed and molecules are electrically neutral and in a vacuum where the won't easily combine via the EM force.

I've looked for a while and can't find an answer to this, hence the post. Ultimately this is a question about how the first pieces of "classical" matter formed from quantum matter. My study of self-organizing systems shows that you need a hierarchical build-up of structures to allow a complex...

Summary: Bell's Theorem rules out any hidden variables but does it rule out some finer structure to quantum particles? At larger scales of the universe, we would see entanglement as cloning. For example, two human clones have the same color eyes because their DNA is identical. I've been...

Thanks for the dialog. I certainly am not saying time does not exist but that it makes more sense to view time as a human construct. I think we'll see that our current notion of time is an emergent property that came about as the universe cooled enough for matter to come together into sizes...

I'd like to read the article on time as an extra dimension and how we allocate our energy moving through the different dimensions of space-time. It just seems like a kludge to add another dimension for time when it isn't necessary. At the sub-atomic level, there are numerous examples of...

John Wheeler made the statement - “Time is what prevents everything from happening at once” However, at a quantum level (and other levels too, but let's focus on quantum and disregard gravity for now) particles can only change state if they interact with other particles. The particles that...
