Important note:
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.

Clip 8: Transition to Primordial Universe (Black Holes Form)
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.

Clip 7: Reheating Begins
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.

Clip 6: Slow-Roll Transition
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.

Clip 5: Bubble Expansion
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.

Clip 4: Tunneling Begins (Bubble Nucleation)
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.

Clip 3: Quantum Fluctuations Appear
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.

Clip 2: False Vacuum Expansion
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.

Clip 1: The Inflaton Field
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.

Yes, the #planet's rate of spin may be affected by #climate change. Potentially catastrophic, but may be mitigated (as well as exacerbated or caused by) variations in the #Moon's #orbit.

The smoking gun signature of detection is this violin plot, known as the Hellings & Downs correlation. It tells us that all the pulsars across the sky are showing a correlated signal that is expected to be produced by the gravitational wave background of supermassive black hole binaries.

We're seeing the Universe shake, rattle and rolling!

Interestingly, data from our PPTA paper - the amplitude signal strength is time-dependent, which is not expected if gravitational wave signals are equally isotropic.

Could be a processing issue, or the pulsars (weirdos) OR potentially GWs stronger in one part of the sky!

This is wild to me!
