Yes, yes, we already know you don't believe in the science of the last century. You disagree with every scientist.The problem is, that in most cases, we aren't actually talking about observed, measured discoveries...we are talking about untestable, unmeasurable, unprovable mathematical models...those are not actual discoveries till they can be confirmed by reality. Yet another example of how post modern science fools itself with instrumentation.
The fact remains that neither heat nor energy have ever been observed spontaneously moving from cool to warm...and the physical law still states as much.
Perhaps they do, but they haven't resulted in any observation of either heat or energy moving spontaneously from cool to warm.
Is heat a form of energy, or is heat evidence of energy moving from one place to another?
Don't you remember we covered you question about the definition of heat before. It is on the previous page of this tread.
You don't like models. But you believe that the energy between light bulbs cancels out leaving a dark streak. That should be testable, measurable, and provable. Why don't you take light bulbs to the nearest grade school and show it to the kids.
These sources all say that bodies at equilibrium radiate equal energy toward each other.

Gustav Robert Kirchhoff (1824–1887) stated in 1860 that “at thermal equilibrium, the power radiated by an object must be equal to the power absorbed.”

In physics, radiative equilibrium is the condition where a steady state system is in dynamic equilibrium, with equal incoming and outgoing radiative heat flux

One form of thermal equilibrium is radiative exchange equilibrium. Two bodies, each with its own uniform temperature, in solely radiative connection, no matter how far apart, or what partially obstructive, reflective, or refractive, obstacles lie in their path of radiative exchange, not moving relative to one another, will exchange thermal radiation, in net the hotter transferring energy to the cooler, and will exchange equal and opposite amounts just when they are at the same temperature.

Kirchhoff's law is that for an arbitrary body emitting and absorbing thermal radiation in thermodynamic equilibrium, the emissivity is equal to the absorptivity.

Imagine a large body that has a deep cavity dug into it. Imagine further that we keep that body at some absolute temperature T and that we have put a small body at a different temperature into the cavity. If the small body has the higher temperature, thenit will radiate heat faster than it absorbs heat so that there will be a net flow of heat from the hotter body to the colder body. Eventually the system will come to thermal equilibrium; that is, both bodies will have the same temperature and the small body will emit heat as fast as it absorbs heat.
Albert Einstein: "... Even in thermal equilibrium, transitions associated with the absorption and emission of photons are occurring continuously... "
This is what Max Planck said in 1914.

Page 31: The energy emitted and the energy absorbed in the state of thermodynamic equilibrium are equal, not only for the entire radiation of the whole spectrum, but also for each monochromatic radiation.
Page 50: "...it is evident that, when thermodynamic equilibrium exists, any two bodies or elements of bodies selected at random exchange by radiationequal amounts of heat with each other..."
