Having arisen from quantum disturbances in the early universe, what phenomenon here and now manifests most prominently in macroscopic physics?

Consider this evidence to be expanded from aboriginal quantal interactions, now observable through a human perspective. Gravity, for instance, does not readily demonstrate its quantum character to our unaided senses.
Bravo! Much like what I am seeking.It's possible to associate the morphology of a galaxy to the particle that originated it?
As I understand it, a hot or cold region in the CMBR is some kind of shadow (or the inverse) of some quantum fluctuation much earlier; more specifically, an overdense or underdense region - in terms of mass - of the universe at the time of matter-radiation decoupling. However this fluctuation morphed - grew, changed shape, deepened, whatever – but there is still, in some sense, a one-to-one correspondence between the initial quantum fluctuation and the hot or cold region (this is probably model-dependent though).meteor said:I guess taht galaxies originate as fluctuations of the differents fields, not only the electromagnetic, but also can exist galaxies originated by fluctuations of the quark field, others originated by fluctuations of the gluon field, etc. Is there any way to predict what fluctuating particle originated the Milky Way?
Perhaps the question can be: It's possible to associate the morphology of a galaxy to the particle that originated it?
I want to put this question in the framework of Loop Quantum Cosmology, where there's no inflaton that can decay into the known particles (though there's still inflation, caused by a different mechanism)
Nereid said:Morphology of nearby galaxies seems to be determined by their last ~1-5 billion years’ history; the morphology of early galaxies is an interesting subject – IMHO we have only a limited idea of these morphologies. One big question for the next decade or two – certainly to the first five years of the JWST – is the nature of early galaxies: their mass function, M/L ratio, metallicity, nuclei, … and morphology. And how well the many theories of galaxy formation and cosmology are consistent with this massive amount of new data.
The most significant, immediate relic of primordial quantum mechanics is the cosmic microwave background radiation (CMB). This is the faint glow of radiation that permeates the entire universe, leftover from the Big Bang and indicative of the early stages of the universe when quantum mechanics was the dominant force.
The CMB provides evidence for primordial quantum mechanics because it is uniform in all directions, indicating that at the early stages of the universe, all matter and energy were in a superposition state, as predicted by quantum mechanics. This is known as the "cosmic inflation" theory.
Yes, the CMB can tell us about the conditions of the early universe. By studying the patterns and fluctuations in the CMB, scientists can infer information about the density, temperature, and composition of the early universe, providing insights into the fundamental laws of physics at that time.
The CMB is a key piece of evidence for the Big Bang theory. The uniformity and temperature of the CMB support the idea that the universe was once in a highly dense and hot state, and has been expanding and cooling ever since. This aligns with the predictions of the Big Bang theory.
Scientists are continually studying the CMB and its patterns in order to gain a better understanding of the early universe and the role of quantum mechanics. This includes analyzing data from telescopes and satellites, as well as developing new theories and models to explain the origins and evolution of the universe based on the CMB.
