Take a look at the Hubble photo archive for examples. The 'eagle nebula' and other similar gas complexes such as the 'horse-head nebula' in Orion are favourites since they show more than one type of nebula. These regions are called dark, reflection, and emission nebulae. a.. Dark nebulae are made mostly of dust. b.. Emission nebulae are fluorescent regions of gas glowing in the presence of embedded stars. c.. Reflection nebulae are cold un-ionized gas. When dark nebulae collide with emission nebulae, features like those noted in the HST image result. The dust pushes its way through the hot gas. Gas along the front edge of the collision compresses and glows hotter. This results in the whitish appearing areas at the edges of the dark 'fingers' of dust. I presume that the temperatures of these areas are near 10,000 K so that they glow like the surfaces of stars of similar temperature, that is, white. Gas at such temperatures will quickly disperse and there is no chance of it forming stars. You presume a lot, An interstellar gas cloud at 10,000 K will not have a spectrum anything like a star at the same temperature. Astronomers can spot the difference without any difficulty. And the fact that stars have been observed in virtually every stage of formation in places like the Orion Nebula and the Taurus region would imply that you are totally incorrect about the impossibility of forming new stars at the present epoch. -- Mike Dworetsky Unlike yourself, I will refrain from personal attacks and stick to the facts. The fact is that the eagle nebula is where, in 1995, that all astronomers were calling "The pillars of creation" - one of the largest known areas of star formation. Now the latest news is that there is possibly less than a handful of stars forming there. I am saying to you that this U-turn will again run off into the distance in maybe another 5 years and they will then say that star formation has ended in the Eagle nebula, in only 10 years! It's apparent that the so-called bright tips in the fingers is simply the interaction of dust and gas and not the formation of stars. Really, all this debate boils down to is, do you believe in the biblical account of creation in 6 days? What cannot be disputed is that the Bible is a real book and was written by many different writers from 2000BC to 200AD. Now, if you can accept that, then read the following extract from the book of Job, written in 1500BC. God spoke to Job out of a whirlwind and asked a series of profound questions dealing with both man’s limited knowledge and God’s awesome power. One of these questions is to be found in Job 38:31. The King James Version [AD1611, revised 1769] reads: ‘Canst thou bind the sweet influences of Pleiades, or loose the bands of Orion?’ The Revised Standard Version [1946] reads: ‘Can you bind the chains of the Pleiades, or loose the cords of Orion?’ The Pleiades and Orion are still with us and are often visible on a clear night and the modern observation of these through astronomy has given us a fascinating insight into this passage. It is in fact a double-barrelled question dealing with two contrasting astronomical phenomena. Let us look briefly at the two objects in question—the cluster of Pleiades commonly called the Seven Sisters, and the stellar grouping called Orion, also known as the Saucepan. To the naked eye the Pleiades seems to be composed of six or seven bluish stars shyly scintillating in the constellation of Taurus. The telescope, however, reveals that the whole cluster is made up of about 500 stars in a spherical group about 50 light years across and nearly 410 light years away. Photographs reveal some of the component stars veiled in a faint diaphanous blue haze of gas and dust, which beautifully reflects the glory of the stars enrobed in it with their various colours. The Creator’s description of it is extremely apt — it is indeed a ‘sweet cluster’ of stars; a delight to behold. Even to the naked eye there is a winsome attractiveness about the group. However, God's statement to Job also includes an astronomical truth of which Job was probably unaware. The cluster of the Pleiades is an odd one out as far as star clusters go. Because of the small amounts of dust and gas between the stars in the cluster, it is called a galactic or open cluster, but unlike many such open clusters, it is not breaking up. It is the classic example of a ‘bound’ cluster.The energies of motion of the individual stars cannot ever overcome the ‘chains’ of gravity and allow them to move away from the cluster. Nor, indeed, is the cluster expanding, as it has been calculated that it would take 1,000 million years to significantly change the diameter of the cluster.This situation is very uncommon as the reverse is usually true of all open or galactic clusters. The constellation of Orion is one of the most outstanding star groupings in the heavens. Photographs of this brilliant association with its giant stars reveal an immense halo of gas and dust in which practically all its stars are immersed. [Part of this nebulosity is visible to the naked eye as the central ‘star’ in the handle of the ‘saucepan’.] The fact that virtually the whole constellation is made up of one massive cluster of stars is in itself unusual. Most constellations are made up of stars merely in line of sight and separated by vast distances. The Orion grouping all lie about 1600 light years away. Despite its size of about 350 light years diameter and despite the vast quantities of gas and dust it contains, the whole system is gravitationally unstable and is steadily expanding outwards.2 The gravitational ‘bands’ holding the constellation together have indeed been loosed, just as God said to Job. Not only that, but even the smaller clusters of stars within the association are fragmenting. On the basis of the stars’ individual motions in one cluster within the Orion Nebula, Dr Peter Van de Voort has shown that the age of the cluster must be less than 10,000 years.This also implies that the whole association must be less than 10,000 years old as both Hoyle and Gamow state that new stars cannot form from clouds of gas and dust unless cloud temperatures are below 5° Absolutes.The observed average temperatures range from 100° Absolute and above, and any collapse of the clouds will only increase the temperature which in turn re-expands the cloud. Thus if new stars cannot form from clouds of gas and dust and the star clusters that have formed are less than 10,000 years old, it strongly indicates that the whole constellation of Orion is less than 10,000 years old. Therefore, there is far more behind God ’s comment to Job that the constellation of Orion is a massive disrupting star cluster than might immediately appear, as it also provides proof for a recent Creation. Now, how could Job, the writer, know about these astronomical insights? the answer is that the whole of the Bible is the inspired Word of God and only the creator of the universe could know the structures of these constellations. So if you now agree that the Bible is the Word of God and that God created the universe and told Job these astronomical insights, then the first 11 chapters of Genesis are also true and the world and universe was created in six days.

Carbon14 should not be detectable after 50,000 years so if there is any detectable then the specimen must be younger and this was the case. http://www.answersingenesis.org/docs/382.asp MarkDJ |

I fear that you have opened the bottle now and there are going to be numerous posts from MDJ that will show that we are all wrong by writing so much drivel that it's really beyond our capabilities to read through it all and address every query and conundrum. Was it not written that Orion shall be the saucepan and that it's handle shall be M42 and that the milk it doth boil over with shalt be thine milky way. Me - I believe that the Matrix is the way forward and am going to adopt it as 'my' belief. What I like about it is the fact that any argument against it as being not real has an equally balanced, unprovable argument that it is. A bit like many other beliefs ;-) Now I'm going to get back to some bedtime reading about the fact that spiral density waves are proof that some galaxies are in need of a damn good clean.

But it must not be beyond our capabilities, however tedious. All that is required for these energetic freaks to prevail is for good people to do nothing - and the current US administration is a ghastly example of just that. Compared to the extreme right religious, Daniel Min is harmless - he has two specific aims, Moon landings and horror-scopes. These guys have a pernicious goal - the replacement of rational thought by the rigid imposition of their interpretation of an ancient book of control.

Why are most galaxies and solar systems 'flat'?
MDJ writted:
: I think the article below should cover your questions regarding entropy. I gave you a statement about entropy, not a question. The rest of your cut and paste is so riddled with errors that it's not worth wasting my time on it. Read a first year undergrad (non-creationist) text on thermodynamics, and if you understand it, you'll see why. Let me put your discussion where it should be. The first chapters of Genesis are not a literal narrative, they is a Jewish interpretation of contemporaneous creation theories. If you wish to take the Bible literally, I suggest that you examine how you are going to cope with Matthew 5:29 - oh, and you can't get a surgeon to do it, as the text says that you should pluck it out. That's before we tackle the laws in Leviticus, whose continuing authority is dealt with in Matthew 5:18. Is the song of Solomon literal? Are his lover's breasts *really* like two fawns that feed among the lilies? Do his lover's lips distil nectar? Choose yes, and you have the ugliest woman in history. Choose no, and you accept that some parts of the Bible are not literal. If you decide that it is not literal, what or who gave you or anyone else the authority to decide that Genesis 1 IS literal? The simple fact is that creation chapters have two primary purposes: One, to differentiate the single God of the Jews from the multitheistic religions of the rest of the world. Two, to emphasise that God is the originator of creation, not part of it. Again, in contrast to the Gods of other religions. Take a look at the Babylonian narratives - they were the creation theories of the time - and see how closely Genesis resembles them. Genesis 1 amounts to, "here is the latest theory that describes creation, this chapter tells you WHY the creation happened". Now, bring this up to modern times, and you can replace Genesis 1 with 'In the beginning, God said, let there be a universe created from a singularity, and let the laws that govern this universe be expressed in the following equations...' That doesn't take away from God, it describes his continually creative personality. When St Paul tells us to be fools for the sake of the Gospel, he's referring to the seeming foolishness of the death of Christ. He's not telling us to empty our brains of critical thought processes and give our will up to a politically motivated creation movement. God gave you a brain for a reason. I advise you not to insult God's gift by failing to use it. Gavin |

Your turn. -- Mike Dworetsky See the other message regarding the truth of the bible and one piece of evidence that the Bible is true. I see you haven't answered my question: what is the scientific theory of creationism, and how can it be tested? As for the people who wrote the Bible thousands of years after the alleged events of creation, can you really believe them? After all, they did not actually witness the events personally. I for one do not accept that the OT was written as a scientific textbook. It contains too many basic scientific errors, such as describing a bat as a bird. You quote some passages from the English translation of the Bible, but it is a matter of subjective and linguistic interpretation just what God is supposed to be implying here. Your post otherwise contains many factual errors about astronomy. As for the 400 years of experiments. I think we could argue to the cows come home and since I don't have any, that's a long time.

That's a start. Contamination of the wood is one possibility. However, it seems unlikely that organic wood could last for millions of years in a bed of basalt, so I suspect the wood was introduced relatively recently on a geological time scale. In any event, carbon dating only applies up to its limit of about 50,000 years and is totally irrelevant to the question of the age of the Earth. The important thing is that you would need to refute all the thousands of consistent radioactive datings of rocks and meteorites that put the age of the Earth well up in the billions of years, as well as all the corroborative independent evidence from stellar evolution, geophysics, etc. You cannot. -- Mike Dworetsky (Remove "pants" spamblock to send e-mail) |
