Conceptual impressions surrounding this post have yet to be substantiated, corroborate, confirmed or woven into a larger argument, context or network.
Below is an article from the magazine 'Physics World'. Parts have been called out and highlighted in red for the purpose of both revealing and discussing the relationship between scientific and design investigation and interpretation of events and experiences surrounding the birth and emergence of a "universe". These "insights" exercise design thinking by applying the use of signs, symbols, metaphor and analogy. References to earlier work will be [bracketed]
The author's ideas, made in reference to this methodology, will be sporadically introduced for purposes of clarification and coherence. Design thinking focuses its' efforts in creating potential by means of generating ideas based upon concepts that may lead to future probabilities.

An expanding universe is simulated in a quantum droplet March 22, 2023 by Campbell McLauchlan
"To study this cosmological model, the researchers began with a flat droplet of BEC composed of potassium-39 atoms in an optical trap. This was the "universe" part of the simulator, and it had a spatial curvature that was related to the average density of the BEC. The quantum field part was played by phonons, quantized packets of sound energy moving through the fluid. These served as analogues to photons and other quantum fields fluctuating in the actual universe.
phonon: a quantum of energy or a quasiparticle associated with a compressional wave such as a sound or a vibration of a crystal lattice.
"In physics, a phonon is a collective excitation in a periodic, elastic arrangement of atoms or molecules in condensed matter, specifically in solids and some liquids. A type of quasiparticle, a phonon is an excited state in the quantum mechanical quantization of the modes of vibrations for elastic structures of interacting particles. Phonons can be thought of as quantized sound waves, similar to photons as quantized light waves."

Quantized vibrations
The phonons were created by firing a laser at the BEC. When the laser was switched off, a phonon vibration spread through the droplet. Quantum particles follow trajectories determined by the curvature of the space time in which they move. Hence, by studyin the trajectory of these phonons, the researchers were able to confirm that the simulated universe had the spatial curvature they were looking for.
Finally, the expansion of space was cleverly instituted by adjusting the strength of interactions between the atoms in the BEC with magnetic fields. Decreasing the interaction strength also decreases the speed of sound, which achieves the same effect as a corresponding expansion of space. The idea is that in as expanded space, it takes longer for a signal to traverse its length. So instead of physically expanding the droplet, one can product the same effect by slowing down the signal.
Quantum fields and a dynamic spacetime interact in complex ways. One particularly curious feature is that an expanding space can product particles - an effect similar to the creation of Hawking radiation by black holes. By tuning the scattering length of the BEC, the scientists experimented with "rampling" up the size of their mini universe in different ways, corresponding to uniform, accelerating and decelerating expansions.
Seeding large-scale structure
What they observed did in fact correspond to the production of phonons, as expected. As these phonons interfered with one another, they produced patterns of random density fluctuation in the BEC. They had thus observed the same phenomenon. predicted to be responsibles for the seeding os large scale structure in the early universe.
Even this proof-of-principle experiment contained intriguing surprises. Not only were phonons produced by the expansionary ramps, but the characteristics of their collective oscillations depended on the type of ramp performed. The phonons contained information that revealed whether the expansion was constant, accelerating or decelerating. This interesting feature, which Sparn says was only understood through the interplay between theory and experiment, demonstrates the possibilities of pursuing these lab-based studies."
