Gravity and the Temperature of Spacetime Gas

Imagine that nature is emergent from pairs of Planck scale fundamental particles, the electrino and the positrino, which are equal yet oppositely charged. These are the only carriers of energy, in electromagnetic and kinetic form. Now add in an infinite 3D Euclidean space (non curvy) and Maxwell’s equations. 𝗡𝗣𝗤𝗚 explores this recipe for nature and how it emerges as a narrative that is compatible with GR and QM, yet far superior in ability to explain the universe and resolve open problems. For 𝗡𝗣𝗤𝗚 basics see: Idealized Neoclassical Model and the NPQG Glossary.

The superfluid gas that implements spacetime has a temperature. In deep space, the temperature of spacetime gas averages 2.7 degrees Kelvin. In the proximity of matter-energy, the temperature of spacetime gas increases due to a wave interaction with matter-energy. What we call the ‘mass’ of a particle (or collection of particles) is related to the energy contained in the particle shell. As the electrinos and neutrinos in the particle shell move on paths determined by their wave equation, they interact with other nearby particle shells (mostly spacetime gas particles); even though no energy is transferred, the ebb and flow of energy in each shell raises its average temperature. As particle shells gain energy their electrinos and positrinos move faster and the radius of the shell decreases according the the Lorentz equation. This is how the curviness of spacetime is implemented and is also a factor in gravity.

Starting from the 2.7K temperature of spacetime gas in deep space, as we approach an object such as a planet, the temperature of spacetime gas will increase as we approach the center of the planet. If we were to graph the temperature and measure the degree of incline, the slope would indicate the strength of gravity at any location in or around the planet. Interestingly, close to the center of the planet, the curve would flatten. At the very center, the curve would be flat (zero slope) and there would be no net gravity, even though the temperature of the spacetime gas would be higher here than at the surface of the planet.

The graph shows the strength of gravity, i.e., the slope of spacetime temperature, as a function of radius from the Earth’s center. Several models are shown that depict various mass density profiles for earth. The simplest model is constant density, as if the composite of Earth was the same throughout- which it isn’t. The most sophisticated is the PREM model, which takes into account the changing composition of particles in the Earth from the mantle to the molten inner core of IRON-56.


From the PREM model chart of Earth’s gravity, we can estimate the shape of the spacetime gas temperature curve from the center of Earth outwards. We don’t know the actual values of the spacetime gas temperature, except in deep space where the black body temperature of spacetime is 2.7 Kelvin.

Planets with more mass would have a higher spacetime gas temperature curve, but would still round off at the center. Objects with even more mass would have even higher core temperatures: small stars, large stars, neutron stars, black holes, and supermassive black holes, for instance.

At some point the temperature of the gas is so high that photons cannot escape from inside that radius. We call such an object a black hole. As we consider black holes of larger and larger density, eventually the peak spacetime gas temperature will reach the Planck temperature, which is the limit of nature. An object that is so dense that a Planck core forms is special because the Planck particles within the core cannot transmit or receive gravitational energy, since they are at the maximum temperature possible, as are their neighbors. In common parlance, the interior of a Planck core presents no mass, even though it is the highest possible energy state of matter.
