It is not about belief, dear Edwin Eugene. The information is real in the sense that there is outside the observer, even if not Perform observation.Information is, for example, number of particles. The universe is in itself, full of information, for the simple reason, that everything can be measured, counted, etc. are numbers, and the numbers are pure information.Therefore,So, for example, the Bekenstein bound is an upper limit on the entropy S, or information I, That can be contained Within a Given finite region of space Which has a finite amount of energy.
[math]I\leq\frac{2\pi RE}{\hbar c\ln2}
[/math]
The vacuum energy density is a pure numerical value, and independent, its value, the observation process, since the expansion of the universe itself, is conditioned to this numerical value.
I do not believe, observe, make theories to explain the observed phenomena, using an informational process of creating algorithms (equations) that give some outputs, and it then taste numerical information outputs of these equations, or algorithms, with the reality of the phenomenon observed physical, measured.All this is information, not subjective beliefs.If I make a theory, with which using an algorithm or routine (equations, etc.), get the measured value of pure number density of vacuum (0.6931 ...), that is objective and real, and it is information. Everything else is to juggle metalinguistic, which are fine for philologists, but does not help the physicists.
