    Cosmic inflation is no indirect evidence
    — Haglund

    I disagree.

    Your good right! If you want to take a fantasy as explanation, feel free!

    If an object is changing, that change must be measurable, then it belongs to the realm of science. May be it is not measurable just because we have not powerful enough instruments, but in that case it still belongs to science, if it is just a problem of powerful instruments. If it is not measurable because it belongs to a realm different from science, then how did you realize that it is changing?

    In other words, the question that your message gives rise to is: what is then the difference between science and metaphysics?

    I don't see any relation between science and metaphysics. Or, science and aesthetics. Or, science and ethics.

    No one is talking about God on this thread. At least not me. Metaphysics need not even address the issue of God existing or not existing.

    Gods are the ultimate metaphysics. The MWI or eternal inflation fantasies pale in comparison, though gods are no fantasy, while eternal inflation and MWI are.

    Not sure I understood. Your belief in God is true but physicists talking about a multiverse is fantasy?

    • Cosmic Inflation is currently the scientific model that matches the cosmology we observe best.
    • One of the consequences of Cosmic Inflation is the existence of multiple "universes" separate from our own.
    • This provides indirect, not conclusive, evidence for the multiverse.

    Almost. God is true, the models are a fantasy, explaining nothing about the nature of quantum mechanics or inflation. The are metaphysical fantasies to bridge a gap in knowledge which themselves are not knowledge with observable features. No one has seen a parallel world or eternally inflating space, which is a totally ridiculous assumption.

    It's not a question of what you and I agree with, it is what the current state of knowledge in cosmology indicates. Again, I'm not saying it's perfect, but it is evidence. Maybe you'll turn out to be right, but for now, it's reasonable for me use the current state of knowledge as evidence.

    Also, it is my understanding that astronomers are currently looking for evidence of other universes associated with inflation.

    Like I said, feel free what you think. There is no evidence that we are a pocket in an eternally inflating fantasy. If you are okay with that, knock yourself out!

    There are even infinite many worlds in MWI. Right now you should be branching into a multitude of them.

    I have provided evidence. You haven't refuted it. You haven't even responded to the substance of my argument. Your only response is "That's fantasy." That's not an argument.

    No need to respond. I'm done with this.
