Both inflation and dark energy violate the energy conditions and refer to the accelerated expansion of the universe. Is this a coincidence, or could some variable dark energy model explain inflation and the subsequent deceleration?

True, what I mean is that we can use Copenhagen or many-worlds to calculate QM things, but we don't use Copenhagen or many-worlds to calculate things that aren't QM. In contrast, with stochastic processes we can calculate QM things and things that have nothing to do with QM. I'm not sure we can...

Is Barandés' stochastic "interpretation" really an interpretation? Something in QM explained using the Copenhagen interpretation can be translated into stochastic terms. Obviously, the translation tells the same story, but in a different way. It does explain the same experimental data...

Exactly.

Comparable to = there is no Turing-type test capable of differentiating them

If we create artificial intelligence comparable to human intelligence, there is no test capable of differentiating them, by definition. However, if artificial intelligence comparable to human intelligence cannot be created, then a test must exist that can demonstrate this, by definition. Is it...

To understand this, it's important to think in terms of tensors. Tensors exist at different levels of order. Through expansion and contraction operations, we can transform a tensor of a certain order into another tensor. In a general way, we have languages, formal languages of order n, then...

The problem with distinguishing between AI and humans in text generation is that there is no test capable of clarifying it; the Turing test is obsolete. A human can simulate speaking like an AI and would be detected as an AI when it is actually human. Similarly, an AI can generate text like a...

Ok, I'll try to be more direct, what models exactly does the BGV theorem ruled out?, what properties should they have? At one point you say: But it's not very specific, can you elaborate on this?

But what's the correction Peter? You said that the BGV theorem can't be asserted as entirely ruling out models that extend infinitely into the past. So, according to you, the BGV theorem allows models that extend infinitely into the past but meet another condition. Which one?

If I understand you correctly, Peter, the theorem you mentioned rules out inflationary models that extend infinitely into the past and also contain singularities, since they would imply that the universe had infinite temperature and density at some point in the past. (Is that correct?) Perhaps...

One question Peter, the term "big bang" predates the inflation proposal. Yet, we call the beginning of reheating the "big bang", a reheating that begins when inflation ends. Would you say the article's question "where the big bang happens?" refers to the start of reheating or the start of...

Space and time, spacetime, is GR. If there was a point in the past where we failed to construct a reasonable notion of space and time, it means that GR fails at some point. Perhaps a theory of quantum gravity would resolve this.

The definition of chance in the Spanish dictionary is: "A combination of circumstances that cannot be predicted or avoided." The definition doesn't prevent a result from always occurring; it simply dictates that it's something that couldn't be predicted or avoided. Could you be referring to...

Does any theorem or principle prevent it, or do you intuitively answer that it's not possible?. I also believe it's not possible, but I was wondering if something in the QM formalism prevents it.
