More Hints at Early Origin of Stars, Galaxies 03/31/2006
Several articles this month showed further evidence for a growing realization in astronomy: stars and galaxies were already mature at the beginning of the universe (see, for instance, 09/21/2005 entry). Some recent examples:
A second area in astrophysics that can be construed as a cloud on the horizon is that recent observations in the years 2002-2003 suggest that not just suggest, recent observations tell astronomers that when the universe was less than 3 billion years old, there were already galactic clusters [03/12/2003]. Not only were there galaxies... but here we have, astronomers have discovered, a modest galactic cluster (I believe that it has something like 30 some-odd galaxies in it) that goes back to less than 3 billion years after the big bang. Thats much too much structure to have after only two and a half or 2.7 billion years of expansion. So that is another problem that astrophysics needs to come to grips with.Goldman compared these challenges to a couple of mysteries at the beginning of the 20th century that Lord Kelvin described as small clouds on the horizon (1) the inability to explain the blackbody radiation spectrum and (2) the lack of deviations of the speed of light through the ether as found by the Michelson-Morley experiment. These two small clouds became cloudbursts a few years later when they led directly to quantum theory and relativity theories that dramatically overhauled our conceptions of space, time and the universe.
Its not a small problem, either, because the extent of the structure that we can discover in the universe has implications for whether big bang and inflation are really capable of providing a model of the universe. So its a small it may seem like a small problem to non-specialists, but within astrophysics its a significant challenge.
And then theres the question of whether we are in fact reading the microwave background radiation correctly. [03/20/2006] Because all of this theory is empirically supported by interpreting extremely minute ripples in the microwave background radiation. And from those ripples, ripples in temperature, temperature inequalities on the order of ten thousandths of a degree Kelvin are thats the basis for trying to explain why there is as much structure as there is in the universe. If were misinterpreting the microwave background radiation data, then really we have a whole new picture of the universe that might emerge. So, thats one set of clouds that one can anticipate that over the next decade we will potentially be seeing significant modifications in our conceptualization of the universe and its origin, and maybe even of its fate.
Goldman suggested later in the lecture one possible new conception of the universe that might emerge in the years ahead: that the universe might be viewed as some kind of information structure. Sound like intelligent design? Sound like instant creation? He asked, and how will we understand that philosophically and physically? Easy: in the beginning was the Word. Consider creation: an idea ahead of its time.
We are still sort of in the Big Bang. You are assuming that if we look in one particular direction, we will be looking back to the point from which we were expelled.
You have to remember the universe has no center, no edge, no surface. The Cosmic Microwave Background, afterglow of the Big Bang from about 300,000 years later, comes at us evenly from all over the sky.
It's the "lookback effect." As you look farther and farther away in any direction at all, you look correspondingly far back in time. The images get older and older because of the time it took the light to get here. In any direction at all, light from a particular event about 300,000 years ABB (After the Big Bang) reaches us as the cosmic microwave background.
The expansion of space is not travel through space. Things appear to move appart because the space itself is expanding. Beyond the part of the universe that we can see there are things being carried by the expansion of space away from us at faster than light, so that we will never, ever see them as they look now. The light from them is being carried away downstream faster than it can swim toward us. This does not violate any part of relativity theory because it is the expansion of space, not the motion of matter through space, creating the "apparent" motion (which we in this case cannot see).
You're exactly right, and we do.
We humans deigning to comprehend the incomprehensible.
Faith is simply faith. What motives God had/has are His to reveal.........if, and when, He chooses.
Doubtless that's what Chrysler had in mind when they designed and built the PT Cruiser: fool everybody into thinking the car is older than it really is. Those devious bastards!
Excuses make for an unpleasant future.
Rom 1:20 For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, [even] his eternal power and Godhead; so that they are without excuse:
This information has been unraveling for six months or so. It has admittedly confounded all of the astronomers who are examining the evidence.
As I have been saying, it is conceptually feaseable to consider that an eternal Creator who is outside of time -- as the scripture teaches throughout by calling God eternal, and revealing prophetic accuracy regarding events that are yet future (unlike any other Holy Book) -- can manifest physical reality like billions of light years like a painter laying paint on a canvas. The scripture describes this reality specifically. Who would have known it would be consistant with Einsteinian relativity theories.
Isa 40:22 [It is] he that sitteth upon the circle of the earth, and the inhabitants thereof [are] as grasshoppers; that stretcheth out the heavens as a curtain, and spreadeth them out as a tent to dwell in:
Within the part we can see (AKA "the Hubble Volume") this expansion causes redshift. It is redshift that makes the initially gamma-ray background look microwave to us. Yes, it's the same thing. Beyond the Hubble Volume, recession velocities are superluminal by simple extension of the same stretching of space that we inside the Hubble Volume.
Is space a physical entity? Like ether? You refer to space as expanding.
It expands. It's not like ether. Ether was postulated to have certain properties that were tested for and failed to show. Ether was supposed to be the stuff light waves were waving IN. That whole mechanism went out in the 1880s with Michelson and Morely. Had ether worked, relativity would not only be wrong but would never have been necessary.
Sounds like a good analogy for a bunch of ignorant goatherders to understand. Telling the truth as they understand it. Interesting how scientists came to the conclusion that the universe expanded as stated in the Bible thousands of years ago.
Again, zero.
Col 1:17 "He is before all things, and in Him all things hold together."
And scientists used to wonder what's holding the atom together. Now they call it strong and weak molecular forces. They wouldn't even consider that they are actually measuring the power of God and not knowing it.
Again, zero.
And you know this because ...?
Aging has been a point of contention between Creationists and non-Creationists all along. Mature galaxies where they definitely should not be, is the proverbial thorn in the side of TOE and conventional Academia's perspective of reality.
The shift continues toward truth and away from speculative deception.
Newly created radioactive matter, as made in a particle accelerator, for example, will contain 100% of its originally created matter. None of it will have decayed into secondary forms yet. Radiometric dating of natural rock is done using that principle. New rock ("new" meaning just solidifying from molten form) will trap air from the atmosphere containing argon from the atmosphere. A certain (very constant) percent of argon atoms are a particular radioactive isotope, which decays at a very constant rate. The ratio of decay to parent product tells the age of the rock.
As you might guess, this system could be prone to error. It sometimes is. That is why, in actual practice, geologists do not rely on any one isotope for dating, but rather use several to see if a statistical distribution gives consistent results. If it does, one can conclude the system has some validity for that sample.
Radiometry is not the only method of dating rocks, either. There is the mapping of periodic magetic domain reversals. There are Milankovitch cycles leading to regular periodic sediment deposition. There are index fossils specific to particular layers of geological strata.
Mature galaxies where they definitely should not be...
An embellishment. Known galactic distribution is still consistent with a Big Bang model, only fine details about it are in debate.
The shift continues toward truth and away from speculative deception.
Exactly. Thanks to modern scientific research, we know with greater certainty than ever before the evolutionary pathways and mechanisms throughout the 3.5 billion or so year history of life on earth. 'Creation scientists' are the only ones trying to deceive people with websites and literature that preys on people's lack of scientific knowledge. Creationism might be an appealing option, but it's completely wrong.
Oh I'm pretty sure God as one hell of a sense of humor. How else to do explain liberals?
And the platypus.
No it doesn't. There are minute differences in it.
At the current time, there is no theoretically plausible way to look "beyond" the big bang. It may be possible to improve on basic theories in cosmology and physics by exposing some new data, but nobody really knows how to look through a "quark soup".
These are exciting times to live in though. And I'm not cursing in Chinese.
Physicists have been making all of the known particles of matter, and many that were predicted by theorists, for decades using accelerators. This is also how many of the radioactive materials used in healthcare are manufactured.
Haven't made any rabbits yet, though. ;)
You've been looking at COBE data.
I'm impressed!
La La La La, Mature galaxies where they shouldn't be means nothing. La La La La...
