This study explores how quantum noise influences the FitzHugh-Nagumo equations, a fundamental model for describing neuronal activity and excitable systems.

These visuals are illustrative only—not precise physical depictions of magnitudes or forces involved. Actual conditions during inflation involved extreme energies (near ~10¹⁶ GeV), densities, and scales far beyond intuitive visualization. My illustrations aim purely for conceptual clarity.
Enjoy exploring our cosmic origins!

This visualization illustrates tiny density fluctuations collapsing into primordial black holes (PBHs) within the hot early universe plasma—originally proposed by Hawking & Carr (1970s). PBHs could influence cosmic structure and potentially explain dark matter. Observational searches ongoing, including data from JWST, LIGO, and future space missions.

Depicted here is "reheating," where the inflaton’s potential energy rapidly converts into hot plasma of standard model particles, marking the Big Bang's fiery start (~10²⁷ Kelvin initially). This transition phase, predicted by cosmologists including Linde, remains theoretically robust yet poorly understood.

This clip illustrates "slow-roll" inflation, introduced by Andrei Linde. After bubble nucleation, the inflaton field rolls slowly toward a true vacuum. Inflation gradually ends as the energy density decreases. "Slow-roll" inflation precisely matches observational constraints from CMB temperature anisotropies.

Visualizing the true vacuum bubble rapidly expanding into the false vacuum. This phase boundary would propagate at enormous speeds, eventually dominating space. This idea relates to Guth's "bubble universe" scenario and the multiverse hypothesis (eternal inflation) proposed by Paul Steinhardt and Alexander Vilenkin.

This clip represents the theoretical nucleation of a true vacuum bubble, transitioning from a high-energy false vacuum—a scenario described by Sidney Coleman & Frank De Luccia in the 1980s. Quantum tunneling initiates bubble formation.
Tiny quantum fluctuations in the inflaton field are illustrated here. Inflation stretched these quantum ripples to enormous scales, seeding all cosmic structures (galaxies, stars). Theoretical predictions by Viatcheslav Mukhanov and Stephen Hawking matched detailed observations.

Here we depict exponential growth driven by the false vacuum’s immense potential energy—space expanded faster than the speed of light, increasing by a factor of at least ~10⁶⁰ in ~10⁻³⁶ seconds. This rapid inflation resolves problems like flatness and horizon issues, as proposed by Guth and further developed by Andrei Linde and Paul Steinhardt.

This clip illustrates a hypothetical quantum scalar field, the inflaton, which cosmologists propose triggered cosmic inflation. Before the Big Bang, space might have existed in a high-energy "false vacuum" state, a concept developed by Alan Guth (1980) to explain rapid expansion.

Ever wondered how our universe began?
I'm exploring cosmic inflation—the rapid expansion of space driven by the mysterious inflaton field. My short, illustrative video clips represent key stages of this theory, starting from a hypothetical quantum field through inflation, quantum fluctuations, reheating into Big Bang plasma, and formation of tiny primordial black holes (PBHs).
Earlier, I shared a visualization showing how some of these PBHs might have evaporated into Hawking radiation, leaving subtle imprints (Hawking relics) that possibly influenced the formation of the first stars and galaxies. https://hachyderm.io/@suzannealdrich/114235968980503011

Negative Time in Quantum Physics: A UToronto Study Challenges Our Understanding
Scientists at the University of Toronto have observed negative time values in quantum experiments! This mind-bending discovery challenges our understanding of time in the quantum realm, suggesting time can seemingly move backward. Fascinating! #QuantumPhysics #NegativeTime #TimeTravel #QuantumMechanics #ScienceNews #UniversityofToronto

From #Qubits to #Qudits: Using a new approach to #QuantumComputing, researchers of our university were able to simulate the behavior of particles in a quantum field – for the first time in two dimensions.
The universe is in constant motion—waves of energy shifting, crashing, and flowing in every direction. In this ever-changing ocean of energy, how can you stay in tune? #zen #zenmaster #dharma #meditation #Consciousness #Energy #Reality #QuantumPhysics #Spirituality #Mindfulness #Philosophy #Nonduality https://youtube.com/shorts/_ZoVDlRUWG0
Our entire universe is made of energy—waves constantly colliding, amplifying, canceling, and resonating. When these waves align, they create harmony. When they clash, they create dissonance. But what does this mean for you? #zen #zenmaster #dharma #meditation #Consciousness #Energy #Reality #QuantumPhysics #Spirituality #Mindfulness #Philosophy #Nonduality https://youtube.com/shorts/81h48bIP5u8
Who are you? What makes you what you are? What is reality made of? To understand the true nature of existence, we must peel back the layers of what we perceive as physical reality. #zen #zenmaster #dharma #meditation #Consciousness #Energy #Reality #QuantumPhysics #Spirituality #Mindfulness #Philosophy #Nonduality https://youtube.com/shorts/yHs_0Wx6l5M
