Yes, maybe I didn't clarify that this was a sarcastic response.

Yes, those official scientists always try to refute everything.

Yes, but it is still worrying that more and more people responsible for this type of decisions think the same nowadays.

Do you have a reference that supports this?

Yes, but perhaps that's because the cited paper is from July 2011, while the main paper on asymmetric radiation of the Pioneers is from April 2012.

Yes, that's more or less it: conformal time would be equivalent to the time in the last 46.5 billion years of a static universe, as shown in the bottom panel of Figure 1.

I don't see how this affects what I proposed. However, if you look at the bottom panel of Figure 1 in Davis & Lineweaver (which is where conformal time is plotted), you can see that the light cone is a straight line, that is, compatible with the Minkowski metric.

The particle horizon refers to the current distance of the most distant (comoving) object that we can, in principle, observe today. The light coming from that object was emitted 13.8 billion years ago and, since the speed of light is constant, we can conclude that this light has traveled 13.8...

I think conformal time could be interpreted as the time it would have taken for light to reach us if the universe were static, that is, if throughout its history the galaxies had been at the same distance from us as they are currently.

No, that's not true. Simultaneous events that occur in the same place remain simultaneous with respect to all reference frames, regardless of whether they are inertial or not or whether they rotate or not.

In one sense, they are postulates of physical theories, which are logical systems. In another sense, they are factual hypotheses that can be verified.

Yes, in the sense that we can differentiate between two types of truth: logical truth and factual truth. In a given logical system, statements are considered true if, using the rules of the system, they can be deduced from the axioms and postulates. Factual truth consists of the complete...

Regarding whether inflation can or cannot be eternal in the past, I found this paper by Leonard Suskind where he discusses the topic. Unfortunately, my level of knowledge isn't up to the task of understanding it in depth, but what is clear to me is that it's a topic on which there is no consensus.

In this paper, I interpret Adrei Linde as saying yes, but no, referring to the BGV theorem: Is this reasoning correct? Isn't it self-contradictory? It seems to me to imply that if all geodesics have a beginning, but if there is no upper bound for the past time at which that beginning took...
