Debate:Is infinite regression ever valid as a form of reasoning, or acceptable as a way the universe works, or came to be? (view source)

I think my previous comment explains where I believe the radiation to be going. Since you know of the term Ideal Gas, you may already understand the balance to zero of the radiation pressure. But it distinctly appears you are postulating what can only be described as an enclosed universe, and in an enclosed volume radiated pressure will '''''not''''' exert positive pressure on the system as a whole. It will be zero in Ideal Gas. --[[User:Knowthetruth|Knowthetruth]] 20:29, 8 March 2007 (EST)

:Outside the Universe somewhere, apparently. Well, that's thoroughly meaningless. The Universe doesn't ''have'' an outside.
:I don't need to postulate an enclosed Universe (by which I assume you mean a finite, unbounded Universe). The radiation is not leaving the Universe, and so its mass-energy is not being 'expended.' It's still available, and in a collapsing Universe it'll end up increasing in temperature (not to mention increasing the temperature of the matter fields it interacts with), and producing increasing outwards pressure, just as compressing an ideal gas with a piston will produce pressure resisting that compression.
