DaleSpam said:That is correct. Photons going up will lose momentum and photons going down will gain momentum. The net effect is that the photon gas has weight.
A photon gas is a theoretical model used in physics to describe a collection of photons, which are particles of light. It is a simplified model that treats photons as particles rather than waves.
In curved space, a photon gas follows the laws of general relativity, which describes how gravity affects the curvature of space. This means that the behavior of the photon gas will be influenced by the curvature of space, and may exhibit different properties than in flat space.
Yes, a photon gas can exist in nature, particularly in high-energy environments such as stars or the early universe. However, it is a theoretical concept and has not yet been directly observed.
A photon gas is different from other gases because it does not have mass or interact with other particles in the same way. It also follows the laws of quantum mechanics rather than classical mechanics.
Studying a photon gas in curved space can help us better understand the behavior of light in extreme environments, such as near black holes or during the early stages of the universe. This knowledge can also help us develop new technologies, such as advanced imaging techniques or quantum computing.
