Re: early predictions/measurements of CMB
Unless we can do the experiments ourselves, or examine the actual data ourselves we have to take what someone else says the data says or the experiments prove. Thus we have to trust them to be telling us the truth and that takes faith.
Is this how you think science operates??? That some one scientist makes some claim about some data, and we all believe her, and trust her word??? Please engage your brain, ICANT, before it fails of disuse.
If we go the imaginary time route, we have to believe imaginary time exists, that the universe existed in this imaginary time and that for no reason it began to expand.
We have to believe that for no reason it began to expand??? What, you mean you don't understand why the Universe expands in the no-boundary proposal? From the way you so knowledgably bandy around these esoteric terms like "imaginary time", anyone who didn't know better would actually think you know something about this...

Re: expansion
I said I do not understand why it STARTED to expand as it was just sitting there in imaginary time
Now as I look back you was agreeing that imaginary time was there and I was saying imaginary God was there.
Rather unsurprisingly, you have no clue what "imaginary" means in this context. Tell me, is your imaginary God related to the real God by a Wick rotation? This is hard-core mathematical phsyics, not wishful thinking...
The only way you can say anything existed prior to T<10-43 there.
Huh? You are suggesting that there is some huge discontinuity in the Universe at T=10^-43, and that existence simply stops at an edge, for the utterly simple reason that we're entering a strong coupling region and we cannot yet describe this region!!! And I am using FAITH to say that that is probably not what happens??? As I have said from the beginning, you have to stop making such idiotic claims if you are not going to look like a complete moron to anyone with the smallest understanding of this subject.

Re: expansion
You make assumptions and you believe them.
You are such an arrogant twat, aren't you? You have NO CLUE as to what I "believe". What I "believe" is irrelevant. You have had various ideas and models explained ad-nauseam, and you do not understand a single one of them. You are told REPEATEDLY that we don't know what happens in the earliest moments, but we have some ideas based upon the relevant mathematics and physics. And you are so confused in your dementia that you insist that somehow, this has something to do with FAITH
Is this the faith that you have, ICANT??? That you DON'T KNOW God exists?
Anyway, as you are so sure of yourself, would you mind telling me what assumptions I believe? I'm fascinated.

Re: expansion
This hypothesis has been around since 1983 and the only support I find for it is here on EvC.
What? You are claiming that Wick Rotation has only been around since 1983??? You really don't have a clue about advanced quantum field theory, do you?
And the only support is here at EvC??? Are you sure you have checked ALL of the journals? You mean there's nothing in Nuc Phys B? And there has to be something in Phys Rev D, surely? They'll take anything. And then Phys Let B, PRL, CQG, GRG, etc, etc. You've checked through all of that? Wow, I'm impressed...
Imaginary time is exactly that, you have to believe it is there
by "FAITH".
So when we use instantons to explain observed quantum tunnelling, that's "by FAITH" is it? And when a model is built to use the same mechanism to explain the early Universe, somehow "FAITH" is involved? Could you explain how?
