the EOS of radiation (photon gas surrounding a black hole)
Why does the EOS of radiation set to 1/3? Where does this come from?

The equation of state of radiation is a fundamental equation in thermodynamics that describes the relationship between the temperature, pressure, and energy density of a system containing radiation. It is given by the Stefan-Boltzmann law: P = ε/3, where P is the pressure, ε is the energy density, and c is the speed of light.
The equation of state of radiation is important because it allows us to understand the behavior of radiation in different systems, such as the early universe, stars, and nuclear reactors. It also helps us calculate the energy transfer and heat capacity of a system containing radiation.
The equation of state of radiation differs from other equations of state, such as the ideal gas law, because it takes into account the unique properties of radiation, such as its high energy density and its ability to travel at the speed of light. This makes it a more accurate representation of the behavior of radiation in different systems.
The equation of state of radiation has many real-world applications, including studying the early universe and the Big Bang, understanding the behavior of stars and their energy output, and designing and optimizing nuclear reactors. It is also used in industries such as astrophysics, cosmology, and nuclear engineering.
The equation of state of radiation is closely related to the first law of thermodynamics, which states that energy cannot be created or destroyed, only transferred or converted from one form to another. The equation of state of radiation helps us understand how radiation transfers energy and how it contributes to the overall energy balance in a thermodynamic system.
