Re: BBT without Inflation
I suggest as a high level , layman's book, 'Wrinkles in Time' by George Smoot to explain how the inflationary model of the big bang made predictions.
Great suggestion, Ramoss, but what you have to understand (and I'm sure you do) is that ICANT has absolutely no interest in understanding any of this. All he wants is to find gaps, problems, and open questions so that he can believe and declare that his theological "theory" of cosmology is just as valid as that of the world community of cosmologists. He would act exactly the same way at any point in the history or the future of science - look at the front line of research and mock the open questions. Don't forget that every "transitional" fossil find is simply the creation of two new gaps...
I wish I had any enthusiasm for addressing this whole issue but ICANT has just sapped me of the will to live - he is the AntiChrist of knowledge. In the unboundless wonders of the Universe, all he can do is say - ooh look, you don't understand this yet, and your model for this isn't quite right.
The simple facts are these: Big Bang comsology has a huge array of evidence, from nucleosynthesis, large scale structure of the Universe, Cosmological red-shift/expansion, CMBR, stellar age, etc. Just as importantly, it is predicted by General Relativity, our theory of spcae-time which has passed every test ever thrown at it. This is sufficient for us to accept that the big bang cosmology is very likely an extremely good picture of what has happened. The original BBT does leave some questions, e.g. flatness, horzion, "monopole". These demonstrated that there was something more than the simple, naive dynamics of the original model. But given that the original model was based on the simplistic models of matter and energy content of the Universe, this was obvious.
One of the most important contributors to the dynamics of the Universe which was missing in the classical model are scalar fields. The Higgs field is the most "known" of these, but most plausible Planckian physics models are replete with scalar fields. We are already seeing the probable effect of one or more scalar fields in the so-called Dark Energy which is driving the accelerating expansion of the Universe.
When the concept of inflation was proposed as the answer to the problem mentioned earlier, it was a real no-brainer. That said, it's not the only solution to the problems, but it does possess some excellent observational evidence. We don't yet have a perfect underlying model of the inflation process, but then these involve guessing the nature of Planckian physics, so it's not too surprising!
So, yes, there are open issues in cosmology - that is why we have cosmologists. And I don't see the situation changing for 100 years or so. But when ICANT makes idiotic statements suggesting that the BBT is dead in the water, he's being, well, an idiot.

Re: BBT without Inflation
My statement was that without inflation the BBT was dead.
Fine, this is an idiotic statement.
my e-mail address is available if you would care to put a test together to find out what I have learned from what you have put forth in the last 15 months.
ICANT, you miserably failed that test the other day when you made your comment of standing on the "balloon" and looking up, seeing "nothing". I should have been howling with laughter but I was kicking in frustration that someone who trys to play hardball with the limits of cosmology would reveal himself such a ignorant fool of the subject. I find it deeply insulting given the time and effort invested.

Re: Re:End
So far my Bible and True Science agree. Evolutionist disagree with my assement and that is OK. They say it is because I don't know what Science says and I say it is because they don't know what the Bible says. Stalemate.
But you are also saying that Buz does not know what the Bible says and that Ray Martinez does not know what the Bible says So which of you has the correct story?

Re: BBT without Inflation
Could you please explain?
The Big bang is a classical theory - it will have shortcoming because of this - it is GUARANTEED to have shortcomings. If it has validity, it should agree with observation to a very strong degree in the classical domain. Problems will be seen in the quantum domain (i.e. in the very early moments, and effects of those early momemts carried forward into the classical regime). This is EXACTLY what we see. The Big Bang model of cosmology will be modified as we gain a deeper understanding of quantum gravity. Inflation is a leap ahead into this regime, where we are guessing at the overall coarse effect of some loosely understood quantum gravity mechanics. The coarse effect has good observational evidence. But inflation will not be the only modification. We have already seen Dark Energy, and there will be much more to come.
But BBT as the classical limit is one of the most solid theories around. That it has issues in the claassical limit is not a problem but a PREDICTION. The issues are what we use as sign posts to the deeper quantum theory. Inflation is one (evidence-backed) possibility. If inflation proves to be incorrect, then all that means is that we have the wrong quantum correction, and we must search further.
Duh we were talking about standing on the surface of the universe if I remember correctly.
Yes, "Duh" is the operative expletive:
ICANT writes:
No, when they use the balloon they are talking about the ants crawling around on the outside surface of the balloon. I never did get it. I kept thinking if I was there and look up it would be blank.
Since there is an absence of ANY THING outside of the universe why would it be stupid to say you would see NO THING if you were standing on the surface of the universe and looked up.
When you can answer this for yourself, you will have understood...

Re: BBT 2.0 Already
Inflation solved that problem in 1981. But inflation has not even reached the theory stage yet. How does it solve anything? I got a lot of notions they don't solve anything.
Do you delight in being an idiot, or does it upset you?
How does it solve anything?
You mean, you don't know, despite all your reading?
I got a lot of notions they don't solve anything.
So once again, ICANT, someone who ponders about seeing nothing as he gazes up off the 2d balloon analogy, claims to have a far better understanding of all of this than the entire cosmological community. Are you claiming that every cosmologist is self-deluded, stupid, and just hoping, praying that inflation wil save them from the disaster of the Big Bang theory? Perhaps you'd care to explain your critique of inflation? Your own words would be nice. And please explain the evidence we have for inflation, if not caused by inflation? And please explain ALL of the evidence for the Big Bang, if it is not actually caused by the Big bang, as you are so desperate to believe.

Re: BBT without Inflation
If Dark energy has been seen, what is it?
A field, what else?
No one has a clue as to what it is.
This is obviously false - many of us have many clues as to what it is.
Dark matter makes up another 23% of the universe and no one has a clue as to what it is.
This is obviously false - many of us have many clues as to what it is.
Do not believe everything you read in poorly written popular science articles. Especially those that claim that GR was published in 1905
The search for Dark energy is 60 years old.
Absolute bollocks - you are misreading the article, revealing your own complete ignorance of this subject.
It does not sound like Dr Zhao has any idea what dark matter or dark energy are.
No, of course he hasn't. It's only his area of expertise but he knows absolutely nothing about it, no more than you in fact...
According to Liddle that is a prediction by hindsight.
Then Liddle is wrong, though it is more likely your reporting that is wrong.
Now did you not explain to me how that the universe was self contained and that everything was inside the universe and there was no thing outside the universe?
Yes, I'm sure I did say this. And you still completely fail to understand it.

Re: BBT 2.0 Already
I do think that they are all blinded by the devil and can not see the truth when they are looking Him in the face everyday.
And the Born Again Christian cosmologists? What about them?
Are you declaring the BBT a disaster that should be replaced as you told me in another thread when you said we need a new theory?
No, in no way is BBT a disaster - but it cannot explain the quantum gravity regime, and that will require a theory of quantum gravity. In the same way that Newtonian Mechanics and Gravity was sufficient for us to reach the Moon, but not to explain the orbit of Mercury with an accuracy to match careful observation.
These are such trivial points...
You act like the BBT is the only hypothesis around that agree with the known evidences.
Yes, it is.
Science is scrambling to find ways to make their theories match the evidence
If irrefutable evidence turned up tomorrow completely overturning BBT, every cosmologist would suddenly experience the utter joy of knowing that their grant cheques will continue for a long time yet, and that the scope for papers and research has just blossomed.
Just as with evolution - we don't hold to the theories because we like them so much, and need to believe in them - we hold to them becasue that is where the evidence leads. When it leads elsewhere, we will move elsewhere. You think that all these issues you raise should make the world community of cosmologists drop BBT. I have news for you. You know jack shit. *WE* will decide when the evidence tips us away from BBT, not you, and we won't care when it does. In fact, we will celebrate if it does. But you just cannot grasp that...

Re: BBT without Inflation
Would that be a field like the Higgs field?
Yes, and similar to the photon field, the strong force field, the weak force field, the electron field, the quark fields, etc, etc.
Or would it be like a cotton field or a corn field?
A cotton field I have seen.
A corn field I have seen.
Idiot.
There is a lot of information as to what it is not. There are many guesses to what it is. Is that what you mean by clue's.
Yes, and if you had half a brain cell you would appreciate that this is rather a lot - but sadly you have no clue so all you do is pour scorn upon those who know immeasurably more than you.
http://arxiv.org/PS_cache/astro-ph/pdf/9901/9901124v1.pdf
Problems were very important.
Enter Inflation 1981.
They still exist but now they are marginal.
No place do I find that any of the problems were predicted.
I see, so on the basis of one paper not mentioning something, you can comfortably declare me a liar... good to know.

Re: BBT 2.0 Already
When a simple explanation would have been just as easy to type?
Strange - I have spent my years here explaining cosmology and fundemental phsyics in great detail, even drawing up diagrams (for you even) to help get the point across. But when it comes to you (and Buz) all I get in return is ignorant argumentationa and idiocy. Have a trawl through the archives at my posts, and ask youself why I treat you differently to everyone else (bar say Buz and randman).
