Gallery QI — Becoming: An Interactive Music Journey in VR — Opening Night.
November 3rd, 2022 — Atkinson Hall auditorium.
UC San Diego — La Jolla, CA
By Shahrokh Yadegari, John Burnett, Eito Murakami and Louis Pisha.
“Becoming” is the result of a collaborative work that was initiated at the Opera Hack organized by San Diego Opera. It is an operatic VR experience based on a Persian poem by Mowlana Rumi depicting the evolution of human spirit. The audience experiences visual, auditory and tactile impressions which are partly curated and partly generated interactively in response to the player’s actions.
“Becoming” incorporates fluid and reactive graphical material which embodies the process of transformation depicted in the Rumi poem. Worlds seamlessly morph between organic and synthetic environments such as oceans, mountains and cities and are populated by continuously evolving life forms. The music is a union of classical Persian music fused with electronic music where the human voice becomes the beacon of spirit across the different stages of the evolution. The various worlds are constructed by the real-time manipulation of particle systems, flocking algorithms and terrain generation methods—all of which can be touched and influenced by the viewer. Audience members can be connected through the network and haptic feedback technology provides human interaction cues as well as an experiential stimulus.
Does the Earth make a sound? Yes! and it’s very eerie!
The European Space Agency (ESA) recently released 5 minutes of haunting, crackling audio. Revealing what Earth’s magnetic field sounds like. Called the Magnetosphere, it is generated deep within the Earth’s interior, at its core. It extends out into space, creating a strong protective shield against things such as charged particles zipping out of the Sun, called the solar wind. And Without this powerful magnetic field, Earth would likely be a barren, cold, dry world. The audio clip you are about to experience might sound like the stuff of nightmares, but sit back, relax and listen to the strange creaking, crackling and rumbling of our planet’s protective shield. This is the sound of the Earth’s magnetic field.

Research from a team of physicists at the University of New Hampshire is advancing the understanding of how protons, which comprise 95% of the mass of the visible universe, interact with each other. The results provide a benchmark for testing the strong force, one of the four fundamental forces in nature.
“There’s a lot still unanswered about both of those things, the proton and the strong force,” said David Ruth, Ph.D. candidate in physics and lead author. “This brings us a little bit closer to that understanding. It’s a necessary piece of two very fundamental things in the universe.”
The strong force governs how what’s internal to the atom’s nucleus—neutrons, protons and the quarks and gluons that make them up—bind together. It is the least understood of the four fundamental forces of nature, which include gravity, electromagnetism and the weak force.
A proposed study of dwarf galaxies could give insight into whether dark matter particles interact with each other.
Thermodynamic phases governed by the strong nuclear force have been linked together using multiple theoretical tools.
Quantum chromodynamics (QCD) is the theory of the strong nuclear force. On a fundamental level, it describes the dynamics of quarks and gluons. Like more familiar systems, such as water, a many-body system of quarks and gluons can exist in very different thermodynamic phases depending on the external conditions. Researchers have long sought to map the different corners of the corresponding phase diagram. New experimental probes of QCD—first and foremost the detection of gravitational waves from neutron-star mergers—allow for a more comprehensive view of this phase structure than was previously possible. Now Tuna Demircik at the Asia Pacific Center for Theoretical Physics, South Korea, and colleagues have put together models originally used in very different contexts to push forward a global understanding of the phases of QCD [1].
Phase transitions governed by the strong force require extreme conditions such as high temperatures and high baryon densities (baryons are three-quark particles such as protons and neutrons). The region of the QCD phase diagram corresponding to high temperatures and relatively low baryon densities can be probed by colliding heavy ions. By contrast, the region associated with high baryon densities and relatively low temperatures can be studied by observing single neutron stars. For a long time, researchers lacked experimental data for the phase space between these two regions, not least because it is very difficult to create matter under neutron-star conditions in the laboratory. This difficulty still exists, although collider facilities are being constructed that are intended to produce matter at higher baryon densities than is currently possible.
The particles inside a proton move around when exposed to electric and magnetic fields, causing it to deform, but this behaviour isn’t well understood.
How does something as immaterial as consciousness arise from something as unconscious as matter?
This is known as the Hard Problem and this theory gets around this problem by explaining consciousness as electrical activity that is aware of its own electrical potential. This is possible because the light photon is the carrier of the electromagnetic force. Because light has momentum and momentum is frame dependent electrical activity in the brain is always in the centre of its own reference frame in ‘the moment of now’ with a potential future that is always uncertain and a past that has gone forever. It is because consciousness is always in the centre of its own reference frame that we have the concept of ‘mind’ with each one of us having our own personal view of the Universe. This is within a process formed by the spontaneous absorption and emission of light a process of continuous energy exchange forming the ever changing world of our everyday life. If our eyes where more sensitive to light we would be able to see that everything is radiating EMR or light continuously because the Universe is never at absolute zero.
In this theory consciousness is the most advanced part of a universal process that can be explained by physics. There are no paradoxes in this theory! We are in the centre of our own reference frame being able to look back in time in every direction at the beauty of the stars. We can also look down into individual reference frames seeing the future unfold photon by photon relative to that frame of reference.
The greatest affect this process of continuous energy exchange has on us is the aging process with photon energy from the Sun cascading down forming greater degrees of freedom for the continuous increase in entropy or disorganization.
But above all this is a creative process with the future coming into existence relative to the energy and momentum or actions of each individual life form. The wave-particle duality of light is acting like the bits or zeros and ones of a computer. This forms a blank canvas for life to form its own future relative to its position and the energy and momentum of its own actions. The Universe is a continuum with spacetime as an emergent property with an Arrow of Time for each object or life form with a future coming into existence relative to their energy & momentum with each new photon electron coupling or dipole moment.
I believe this is what we are seeing when we see an artist at work we are seeing the future unfolding relative to the energy and momentum of the artist!
In this theory creation is truly in the eye and hand of the beholder!

Quantum Atom Theory on facebook with diagrams and scientific experimental videos:
While the quantum world is not far away, shrinking down to the size of an atom to experience the quantum realm would be difficult for humans.
Just in time for Halloween, scientists have discovered something spooky and strange occurring at the edge of the solar system: The heliopause — the boundary between the heliosphere (the bubble of solar wind encompassing the solar system) and the interstellar medium (the material between the stars) appears to be rippling and creating oblique angles in an unexpected manner.
The general concept that the heliopause changes shape is not new; over the past decade, researchers have determined that it is not static. They made this discovery using data from Voyager 1 and Voyager 2, the only two spacecraft to exit the heliosphere thus far, as well as NASA’s Interstellar Boundary Explorer (IBEX) satellite, which studies the emissions of energetic neutral atoms (ENAs) that are created when solar winds and the interstellar medium interact.
