James,
I did notice your question first time around, and I am sorry I haven't replied until now. The "Answers in Genesis" (AIG) page your posted got the numbers right, but their
conclusions are, well, - hopefully based on ignorance.
Down through the first paragraph of the section "Stars Were of Supernatural Origin" (strange to have that in past tense...) they are quite right and I have no objections to
what they write.
But then they state (about gas clouds collapsing to form stars)
"However, such compression would be very difficult to accomplish because
gas has a tendency to expand, not contract."
Here they appeal to your everyday experiences with gases in the Earth's atmosphere - they disperse and often rise in our atmosphere. Now, this is a very poor analogy to the case of giant molecular clouds which host star formation. Being millions of times heftier than the Sun they are self-gravitating - they produce their own gravitational field, which is very different from the circumstances here on Earth. The densities in these clouds can be lower than the best vacuums we can produce here on Earth, but the vast size of these clouds means they can still pack a lot of mass. The clouds are turbulent and some parts will have much larger densities and can start to collapse.
They continue:
"In fact, if a gas cloud were to begin to be compressed, it would drastically increase its pressure, magnetic field, and rotation speed. All of these factors
would strongly resist any further compression. The compression of a nebula
would be stopped long before any star could form."
The main show-stopper is pressure, whereas rotation and magnetic fields scale in a way that makes them minor players in this game. So it is mainly a balance between gravity and pressure. This balance will be struck at some radius of the contracting sub-cloud, and contraction will stop. As you compress a gas adiabatically (without adding or removing energy from the gas) the temperature will increase, as well as the density, thereby increasing
the pressure:
pressure = constant * density * temperature (approximately)
If we could lower the temperature, the balance would hapen at a smaller radius - more
compact sub-cloud.
Enters atomic physics: The electrons of an atom can populate a great number of states or orbitals that all have different energies. The one with the lowest energy, is the ground- state. If you excite an atom to one of those higher energy states, the atom will spontaneously decay into the ground-state, emitting a photon that carries away the energy difference between the two states. In our gas-cloud the most likely excitation mechanism is collisions between particles - another one is excitation by photons (since the gas has a finite temperature the gas will glow with a specific spectrum) - the important part is that there is only one decay mechanism. This means that more photons will be emitted than were absorbed and the difference will be extracted from the motions of the particles between each other - the temperature of the gas. This is called radiative cooling, and it can be very efficient. In fact our models indicate that the collapse will take place in less than a million years (in contrast to normal stellar evolution taking billions of years). We don't have strong observational evidence for the speed of this phase since it is still slow on a human scale, and since we have seen too few to be able to do the statistical analysis to obtain lifetimes of
proto-stars.
AIG further states: "And despite claims to the contrary, we've never seen a star forming."
I have several issues with that statement:
a) Observing stars is like taking a photo of a busy pedestrian street and from such a single snapshot find out how people change during their lives. The relevant question here, is
how many births have you witnessed while shopping, or commuting to work?
We have just recently found the maternity ward and made instruments (space-based infrared telescopes) to peer into the maternity ward (cold, dense, dusty gas-clouds). b) There is no sign at the surface of a proto-star turning into a proper star, and the process is gradual anyway, with the nuclear fusion at the centre, slowly ramping up. ^ c) We have seen the pregnant mothers and the newborn babies being carried away to the nursery. Still assuming there is no birth taking place in between seems a bit silly to me.
But we are of course still observing to cover the full process.

To be continued (soon).

Regner,
I realised that my question in the email below, to you, Regner, was contained within my short responce to Paul, so you might not have noticed it. So I thought I might resend so that you would know I had asked you something and could repond, even if to say no. I am curious to know if you see anything substantially wrong with the reported facts in the linked article.

    Paul,

    I wonder, Regner, if you have the time to read this short article
    and give us your thoughts on the "facts" reported within.

        I truly despair when I read <From sungenis@xxxxxxx Wed Dec 19
        14:05:43 2007> this thread, and similar. (See below).
        Firstly, the paranoia. It seems to be the first shot fired by
        those who can't get their views accepted by honest workers in
        the fields in question. But worse, there is the flood of words
        which seem designed to attempt to smother the discoveries of
        the past 500(?) years. These discoveries are open to disproof
        by any who can demonstrate falsity. No one does, which leads
        to the possibility that no one can -- not because of
        ineptitude but because the disproof does not exist.
        If, instead of the flood of words, we were to be treated to a
        series of simple, testable geocentric hypotheses equivalent to
        F = ma and those which flow from it, which lead to the
        inescapable conclusion that the Sun with all its mass circles
        the tiny Earth then you'd have a prayer. It would also help
        your case if you could explain how the enormous body of
        interlocking and mutually supporting knowledge of the physical
        functioning of the Solar System can be repeatedly demonstrated
        and yet be false.
        However, I think the thing which bothers me most is resorting
        to Maxwell and quasars and alleged false proofs of relativity.
        This is taking a steam hammer to crack an egg. If the Sun
        circles the Earth you should be able to show it within the
        sphere encompassing the Solar System. My guess is that if the
        universe ended at the Oort Cloud, eff would still equal em-ae
        and the Earth would still circle the Sun.
        I have two beautiful examples of how science triumphs. The
        first concerns Gregor J Mendel who first worked out the
        principles of inheritance (not money but genes). He was an
        Augustinian priest (a cloistered order I think - in any event
        he worked in isolation) who when he died, had his papers
        burned by his abbot because the abbot feared that this
        "knowledge", if widely available, would be a threat to the
        church. Today his work is recognised and respected because it
        has utility, ie -- it works.
        The other is the disastrous effect of doctrinal domination of
        science, in this case the Soviet Union and its "Soviet theory
        of Genetics" (as though ideology could influence truth, ie --
        what is). The man the Soviets chose to back was named Lysenko.
        After 50 years(?) of failure to demonstrate the truth of his
        claims, with the Soviet Union falling further and further
        behind in this matter and the matters upon which this false
        view of genetics bore, they had to reverse their position. His
        theory did not have utility, it didn't work.
        The point I'm making is that science is about discovery -- it
        is not about invention. If you seek to disseminate the theory
        that in a gravity field the pan with 900g in it will sink and
        the pan with 1000 g in it will rise, you will forever be shown
        to be wrong.
        Paul D
        PS Almost missed this one. From your post below -
        '...then the science establishment has no right to teach that
        heliocentrism is correct, much less been scientifically
        proven. Hence we should have a voice in academia today.'

        Would you also give an equal voice to a flat Earth on four
        elephant's backs on a turtle's back in a really big puddle?
        The concave Earth? A flat circular Earth in the middle of a
        Tychonian system with the South Pole a really high wall of ice
        at the edge? And all the other alternatives? I'm sure the
        proponents of these alternative systems have explanations
        which they regard as at least as valid as geocentrism and that
        if you get representation then so should they.
        It's interesting how the proponents of all the odd ball
        theories seem to think it is just them against orthodoxy.

        From sungenis@xxxxxxx Wed Dec 19 14:05:43 2007 Re:Integrity in
        science.
        RT: So speculating on peoples motives is examining evidence? I
        don't really care about peoples motives, social status,
        gender, hair-colour, whether somebody has found a quote that
        can fit into their world-view, etc., etc...
        RS: I wasn’t speculating. The quote tells us precisely what
        Hawking’s motivations are – to keep the earth out of the
        center of the universe, despite the fact that the cosmological
        evidence shows him that it best fits in the center, and that
        he has to concoct an alternate cosmology just so that he can
        keep the earth out of the center. And there are more quotes
        from Hawking that say the same thing. If you would read the
        book, you would see dozens of such motivations by today’s
        scientists to keep the earth out of the center, in spite of
        the evidence before them. The reason is simple. They know
        precisely what it means to have the earth in the center – it
        means that their whole career in science will be over and they
        are going to admit that science took a wrong turn 500 years
        ago. But today, a scientist can’t even express his doubt in
        evolution without losing his job. Can you imagine what
        academia would do if you, Regner Tem., said the earth was
        standing still in space? You’d be picking up your last
        paycheck. If you come to this discussion believing that
        one’s philosophy, his religion, his commitments to the
        establishment, his upbringing, etc., don’t effect how he
        views the evidence, then you’re not living in reality.
        This is precisely why I gave you the Michelson-Morley
        experiment as my first piece of evidence, since we are told
        there are at least two ways to interpret the results. If one
        is trying to keep the earth moving, one will interpret M/M
        Einstein’s way (and Einstein said so, by his own admission,
        and you can read his words in GWW. His motivation was to keep
        the earth moving, even though the salient features of the
        experiment were suggesting that it was not be moving). If you
        want the earth to remain still, you will interpret the results
        another way. As a scientist, you know as well as I do that
        INTERPRETATION of the experimental results is the crux of the
        issue. And since interpretation is often a mixture of
        subjectivity and objectivity, then interpretations of
        experiments are always subject to scrutiny. What we are trying
        to say is (a) Einstein’s way of interpreting M/M not only
        avoids Occam’s razor, it is, for all intents and purposes,
        absurd; and (b) since a fixed earth is a valid, reasonable and
        scientifically supportable interpretation of M/M, then the
        science establishment has no right to teach that heliocentrism
        is correct, much less been scientifically proven. Hence we
        should have a voice in academia today. But the reason we
        aren’t allowed to have a voice is that there are many
        ideologues, like Hawking, Sagan, Gould, Davies, and hundreds
        of others, who simply don’t want the public to know what the
        alternative interpretations are. I’m not making this up,
        Regner. I have documented their motivations by their own
        printed words, and that is precisely why I spent four years
        gathering quotes of their "motivations" in GWW. There is no
        argument. They’ve told us what their agenda is, and I
        suspect you have the same agenda.
        RT: I care about the physical evidence. I have seen a few
        excerpts of your books, but, as I have said before, I don't
        have time to read the thousands of pages. Since you wrote the
        book, you should be able to distill the key findings into a
        couple of challenges for me, and we can take the discussion
        from there and get into all the details. That is what I would
        like to do, because I think it would be the most efficient.
        Do you have objections to that?
        RS: Ok, you don’t have time, and I don’t have time. I’m
        a busy man like you. I’ve got nine kids and three book
        deadlines to meet, on top of coaching two basketball teams.
        The reason I gave you the Michelson-Morley experiment to
        explain first is that your answer will tell us exactly how you
        approach this whole issue. I consider it a test for you,
        Regner. I don’t know anything about you other than you came
        on board this discussion group. Hence, not to accuse you now,
        but if I see you fudging with the evidence of the first
        challenge I give you, I can safely assume you’re going to do
        the same with the other four challenges I have, and thus
        it’s not worth my time. I’ve been through this many times
        before with naysayers, and I’ve been teaching for 35 years,
        enough to know when someone is just being obstinate and when
        someone really has solid objections. I want to see which one
        you are.
        And practically speaking, if you’re involved in an intense
        discussion with Allen, and as you say below, "I am sorry that
        I don't have time to take on more than one discussion at a
        time, but that is how it is," then my suggestion is not to ask
        for more than you can handle by insisting that I give you four
        challenges instead of one. Obviously, as is now the case with
        Allen, when you give your answer to the first challenge, I’m
        going to come back with questions and objections for you, and
        we are going to go round and round on it until it is
        exhausted, which may take months. So why would we want to clog
        up the works with four other challenges that are going to
        require the same intensity? It doesn’t make sense to me.
        For the record, the other challenges I was thinking of giving
        you but held them back in order to see what you would do with
        the first challenge, involve such things as: (1) center of
        mass; (2) parallax and retrograde motion; (3) centrifugal and
        Coriolis forces; (4)Arago, Hoek, Airy telescope results;
        (5)Maxwell’s equations; (6)quasars, gamma ray bursters, etc;
        (7) the Sagnac experiment; (8)false proofs of relativity; (9)
        difficulties with a rotating and translating earth, and many
        other such issues.
        But again, they are all superfluous if we can’t get to first
        base with the first challenge. This is the most reasonable
        approach, and I hope you will agree.
