Author’s impulse: Big-bang models is actually extracted from GR because of the presupposing your modeled universe stays homogeneously filled up with a fluid away from amount and you will rays. The new refused contradiction was absent due to the fact into the Big-bang models the every-where is bound so you’re able to a limited regularity.
Reviewer’s comment: The author is wrong in writing: “The homogeneity assumption is drastically incompatible with a Big Bang in flat space, in which radiation from past events, such as from last scattering, cannot fail to separate ever more from the material content of the universe.” The author assumes that the material content of the universe is of limited extent, but the “Big Bang” model does not assume such a thing. Figure 1 shows a possible “Big Bang” model but not the only possible “Big Bang” model.
Although not, in traditional community, the homogeneity of the CMB try was able perhaps not by
Author’s response: My statement holds for what I (and most others) mean with the “Big Bang”, in which everything can be traced back to a compact primeval fireball. The Reviewer appears, instead, to prescribe an Expanding View model, in which the spatial extension of the universe was never limited while more of it came gradually into view. widening the universe like this (model 5), but by narrowing it to a region with the comoving diameter of the last scattering surface (model 4). This is the relic radiation blunder.
Reviewer’s review: This is not the “Big-bang” model but “Design step one” that is supplemented which have a contradictory presumption by the copywriter.
Author’s reaction: My “design step one” is short for a huge Fuck design that is none marred of the relic rays error neither confused with an expanding Have a look at model.
Reviewer’s comment: According to the citation, Tolman considered the “model of the expanding universe with which we deal . containing a homogeneous, isotropic mixture of matter and blackbody radiation,” which clearly means that Tolman assumes there is no maximum to the extent of the radiation distribution in space. This is compatible with the “Big Bang” model.
Author’s response: The citation is actually taken from Alpher and Herman (1975). It reads like a warning: do not take our conclusions as valid if the universe is not like this. In believing that it is, the authors appear to have followed Tolman (1934), who had begun his studies of the thermal properties of the universe ahead of he had become familiar with GR based models. He thought erroneously that his earlier conclusions would still hold also in these, and none of his followers corrected this.
Reviewer’s feedback: The very last scattering facial skin we see now are a two-dimensional round cut-out of your entire market at that time of last scattering. Inside a good billion many years, we are researching white away from a larger history sprinkling facial skin on a comoving length of about forty eight Gly where count and light was also establish.
Author’s response: This new “last scattering epidermis” is merely a theoretic build contained in this a good cosmogonic Big bang design, and i imagine I managed to get clear one to like an unit will not allow us to discover that it surface. We come across something different.
This means that the author wrongly believes that reviewer (while some) “misinterprets” what the journalist claims, when in reality this is the journalist whom misinterprets the definition of your own “Big bang” design
Reviewer’s comment: The “Standard Model of Cosmology” is based on the “Big Bang” model (not on “Model 1″) and on a possible FLRW solution that fits best the current astronomical observations. The “Standard Model of Cosmology” posits that matter and radiation are distributed uniformly everywhere in the universe. This new supplemented assumption is not contrary to the “Big Bang” model because the latter does not say anything about the distribution of matter.
