We are interested in truth and that is why question paradigms is important. The true ones hold up over time.

Statistics of redshift periodicities


Claims that ordinary spiral galaxies and some classes of QSO show periodicity
in their redshift distributions have been investigated using high-precision data and
rigorous statistical procedures. The periodicities are broadly confirmed. They are
easily seen by eye in the data sets. Observational, reduction, or statistical artefacts
do not seem capable of accounting for them.

’Big Wave’ Theory Offers Alternative to Dark Energy

Ripples in a pond
Temple compared the wave to what happens when you throw a rock into a pond. In this case, the rock would be the Big Bang, and the concentric ripples that result are like a series of waves throughout the universe. Later on, when the first galaxies start to form, they are forming inside space-time that has already been displaced from where it would have been without the wave. So when we observe these galaxies with telescopes, they don’t appear to be where we would expect if there had never been a big wave.
One potential issue with this idea is that it might require a big coincidence.

For the universe to appear to be accelerating at the same rate in all directions, we in the Milky Way would have to be near a local center, at the spot where an expansion wave was initiated early in the Big Bang when the universe was filled with radiation.

Temple concedes that this is a coincidence, but said it’s possible that we are merely in the center of a smaller wave that affects the galaxies we can see from our vantage point - we need not be in the center of the entire universe for the idea to work.
You’re misunderstanding the analogy. This analogy does not indicate that galaxies are located in concentric circles from the center (especially since there is no center to Big Bang.) It’s talking about the rate of expansion; and the rate ISN’T the same in all directions. We know that the rate was very fast long ago, slowed down, and is now speeding up again. So galaxies closer to us (thereby also representing newer because of the time that it takes light to get to us) appear to be receding more rapidly.

The wave description is an analogy, not an actual description of the distribution. You can look at a cosmic radiation map and see that there’s nothing concentric about it.
 
But the Earth cannot be the center of the universe. There is no center. You can have it be a center as related to another thing - perhaps even as related to a few things. Not as related to all things.
I’m not saying it is. I’m saying actually quite the opposite. What I meant was only that it is possible to construct a mathematical model that would show relationships as if that were true. That is why I said in effect that accepting that as a baseline is an astronomical asss-umption.
 
Yes, and if you go look at the animations linked to above, you will see that averaged point for the entire system is all over the place, yet relatively speaking, the Sun is the one the others go around; the sun doesn’t g around any of them, whatever the dynamics of the barycenters are. It is this very movement that has allowed astronomers to detect planets around other stars.
 
sigh cradle Catholics…
No of course not. God did not make the stars and planets did he? and he sure didnt create science so lets just leave him out of this shall we? :rolleyes:

what an absolute stupid and idiotic statement to make puzzleannie. 😃

To the other posters. I did not come here to defend Geocentrism. But looking for some Orthodox teaching on astronomy as opposed to the bull that makes its way across our screens today.

Like I said I dont mind if the book contains heliocentrist views just as long as its somewhat well- rounded and informative.
why thank you Steve, and how is your day going

Astronomy in no way denies that God created the heavens and all that exists, but it seeks to explain the rules by which He set them in motion, in scientific terms. There is no conflict between science and religion, or by creation accounts in scripture, with scientific explanations of the order of creation and of the heavenly bodies.

Why not look for astronomy teaching on a science site, not a Catholic apologetics site, was my suggestion. If it is not helpful to you, you can ignore the advice without indulging in opprobrious epithets.

if you are looking for self-identified Catholics who promote geocentrism and other non-scientific ideas through the misuse of scripture I am sure someone here can point you to those sites.

Galactocentric velocities are plotted against distance in Fig. 17.3. It has slope
61.1±5.0 km s−1 and intercept −4.7±18.2 km s−1. This intercept is remarkably
small: Either the expansion of the Universe is centered on the nucleus of our Galaxy (!), or this is a manifestation of the anomalous quiescence of the local neighborhood, remarked on by Baryshev et al. (2001), and others. “Anomalous” is in relation to expectations from CDM N-body simulations, which predict order-of-magnitude higher velocity dispersions for Local Groups, with or without biasing (Governato
et al. 1997).
 
But not actually. The sun also orbits this point.
I agree, but the gravitational impact of the Sun on any object in the solar system is so great relative to the object, that in many cases for practical purposes the difference can be ignored.

Of course, the Sun wobbles a bit due to the external gravitational impact; this principle is in fact one of the key ways that we can find extra-solar planets - by looking at the wobble of distant stars and “backing into” the planets that must be causing that wobble.

Since no site is referenced for this, I can’t even begin to check it. But the concept is incorrect.

Buffalo, this is a couple of occasions now where it appears that you may be getting “buffaloed” by pseudo-science that masquerades as real science - perhaps somehow with the intent of tying in the existence of God.

I would offer you a couple of perspectives.

First, I believe - and I suspect that all Catholics believe - that God created us with free will. There is no scientific proof for this, but I believe it nonetheless. It fits with my experience and view of the world. There are some forms of evidence that justify this. For example, it is arguable that the “statistical freedom” apparent in Quantum Mechanics/Quantum Electrodynamics may be implicitly necessary for free will to exist. On a large scale, things appear deterministic. But on a small scale they are not. Chance enters the equation. It may well be that it is this lack of determinism on a small scale that provides the ability for us to have free will. IF a form of string theory further describes how the universe works, this underlying random cacophony may provide the further opportunity for free will.

That said, ALL that we know, as individuals, involves some amount of belief. I cannot know that whether or not this is all a dream. I cannot define exactly what reality is; My observation (especially at a quantum level) impacts the result.

On some level, I must accept reality on a basis of faith; some initial beliefs mus be treated as axioms of reality. After that, we can build a “system of reality.”

THAT said, for us to FREELY choose God, there must be an amount of faith involved. If there is a proof of God, then faith is removed, and our choice of God is less free. In fact, if there were a proof of God, NOT choosing Him would be a “litmus test for intelligence” as it were. We would be supreme fools NOT to choose Him.

I speculate that this may be how we primarily differ from the angels; they have a proof of God, we do not. (Again, this is a speculation only.)

My point is this. If this philosophy is correct (and it would seem to fit into most views of Christianity), THEN we can conclude that a proof of God is purposefully lacking within our universe. Science cannot prove Him, and NEVER will.

Gödel showed that for certain kinds of systems, it is possible to prove that not all true statements can be proven if the system is consistent (i.e. - non-contradictory). I believe (but cannot prove) that our universe falls into this category, and that God is true, but unprovable.

Therefore, looking for God in science always contains some folly. Trying to find science that conforms to God and so proves Him, like ID - is the height of folly in such a system.

This doesn’t mean that studying science is not theologically worth while. We can learn about an artist by studying the works he created. We can learn about the ultimate artist by studying His works as well.

For example, we can see that God is a God of rules. But NOT ad hoc rules, and generally not complex ones. (This is why Occam’s Razor works!) There may be many rules, but they generally appear to be reducable to a few key rules. We know today that in our universe there are 4 fundamental forces; we speculate that at higher temperatures (like those near the time of creation) that these turn into 3, then 2, then 1 force as the energy level increases. 1 force, one rule at its simplest level. We have shown that this is actually true when increasing temperatures - the “Weak nuclear force” and the “Electromagnetic force” DO combine to form the “electro-weak” force. Whethr this process will continue at higher energy levels we do not yet know.

I hope that this sharing helps you to see that such “proofs of God” are unnecessary, and that “speculations ARE speculations”, sometimes with some evidence, sometimes with very little.

But with what we know currently, listening someone regarding ID, for example, is not that different from associating with an astrologer.

There ARE legitimate areas of physics (that are a bit more speculative, but they don’t assume ad hoc hypotheses) that all physics is really about converting and exchanging information - that, in essence, "the formulas are real, and that “reality is only” a manifestation of the formulas. Again, this is a speculation, and whether this will every be provable is a question; it may be that this perspective does nothing useful other than to give us another view of the universe.

I know this is a bit off topic, but I hope that the general flavor and context adds to discussions.

I gave you the link in the prior post. Now it is evident who didn’t read it. You get another chance though. 🙂

IDvolution is where faith and reason intersect. In that area both must be true. A Catholic (namely me) is free to investigate this intersection and build/confirm a philosophy around it. I like IDvolution because it is total agreement with Revelation. Theistic evolution has issues. Even materialists will tell you so. TE’s are the one’s trying to force fit reasoning by changing the constant understanding and teaching of Scripture and Tradition, aka scientism.

An understanding of IDvolution is in order. It is not Intelligent Design the science. It is beyond that, the next step if you will. ID does not say who the designer is, just that there is a designer. IDvolution says the designer is God. IDvoluton is not constrained as it is using the latest science as a foundation as well as Revelation. IDvolution does not claim to be science, but again the latest science supports it. That’s OK.

ID the science is not the same as astrology. Your comment is bogus. You are sadly mistaken about this. :nope: It is about observations and calculating the odds. These calculations are continuously showing that chance does not explain the universe, design and purpose do. This is consistent with Catholic teaching who know the world to be intelligible and worthy of exploration.

Now yes God has established some discoverable laws and we seek to find them. We ASSUME they act the same way across the universe. They may not. We can ask ourselves though why God did not tell us that bananas are blue.

Again, if one is walking down the beach and sees left footprints as far as he can see what should he conclude? So we walk and walk and speculate the possibilities. We then see a guy and he tells us (reveals) how they were made. We have to respect that.

And since you brought Godel up , he might just agree with IDvolution.

When you say “the latest science supports it”, what exactly do you mean? If you mean that the latest science allows the possibility of IDvolution, then sure, I can accept that. But if you mean that the latest science supports it to the exclusion of all competing theories, then you are claiming that IDvolution is a scientific concept that can be distinguished from competing theories on strictly scientific grounds. That I find false.

The “science” that I have seen trying to justify IDvolution has a lot of “calculating the odds”. Probability is indeed a mathematical concept - and therefore a scientific concept. But it is one that is very poorly understood at an intuitive level - especially when the odds under consideration are very close to 1 or very close to 0. Thus it is easy for someone to “prove” to the non-mathematician that a certain thing could not have happened by chance.

Normally, when presented with a hypothesis, a scientific investigator could perform an experiment. If someone says it is unlikely to toss a coin 10 times and get exactly 1 head, then I can go and do some coin tossing and see for myself. The important thing in probability is that there be a space in which the event can have numerous instances. Then once an hypothesis is established, you can look at new instances of that phenomenon to see if there is continued evidence for the hypothesis. But in the case of our universe, we have only one instance to look at. We can’t go out and look at many other universes and see how many of them have a certain astronomical constant.

To put it bluntly, none of the mathematical “proofs” of IDvolution qualify as proofs in the scientific sense. I’ve seen too many tricky paradoxes that look so convincing until you examine them closely enough to find the flaw in the reasoning. Of course you could say that neither you nor I are qualified to evaluate the claims of IDvolution and that we have to rely on experts to do the analysis for us and trust them. In that case it comes down to whom do you trust. Here we leave the realm of science and enter the realm of belief again. And to me the critics of this “science” have the stronger argument.

I should also say that as a matter of faith, I believe that God did intelligently create the universe and plan how evolution would proceed. But I think he did it so cleverly that you will never be able to catch Him in the act.

Sigh. No. Seriously, read something like “Personal Knowledge”. He discusses the very errors you are making. Assumptions do not prove themselves, and this is sad.

Bananas are not blue. They are yellow. In the ultraviolet spectrum, their color varies as they ripen.

I can see that discussions with you may not be useful until you decide to be open to truth, rather than assuming what it is that you wish to prove.

Yes, current science allows the possibility. That support grows stronger everyday as we go deeper into the cell. Eventually, evolution will fall by the wayside as it will no longer be sufficient. One can see the shift happening right now. The modern synthesis is being replaces by the EES, self organization. (the odds against just jumped way up, life for evo has gotten way tougher) Most of IDvolution is biologic.

If you look at the supporting resources here, most of this is not about odds. It is what we see and have discovered.

We have studied the DNA language we now know it came from a mind. When we look for design we do apply odds of it appearing by chance and find consistently the odds are so low. The fine tuning of the universe is about infinitesimal odds. So you can see how I find support for IDvolution in both discovery and odds. The intelligent design studies are the workhouse that gives confidence to IDvolution.

We see complexity and purpose in the machinery of the cell. We now know the first cells were complex. We see abrupt appearance in the fossil record and then stasis over and over. We also now know that DNA actively through several iterations fights against mutations. That affects the odds of a mutation taking hold by magnitudes. We see rapid adaptation of organism and in the case of the finches their beaks returning to what they were before.

However, IDvolution can be applied to the universe (physics and astronomy) in that God “breathed” information into time, space and matter.

As bananas ripen they reflect blue in the UV spectrum. The point is why didn’t we know this until recently?

Likewise, are you open to truth or a disciple of the current paradigm?

I am not using personal knowledge in formulating IDvolution. I am using the clear teachings of the Church on the faith side, and emerging science on the reasoning side.

What assumptions do you claim I am making?

Thank you very much for agreeing with me. It is so rarely I get a chance to be right that I must insist the sun orbits as the planets also orbit. By saying the sun wobbles a bit due to gravitational pull gives a wrong and unhelpful impression of the mechanics of what is happening. The sun orbits, it is not the fixed center of the solar system and as you say it is important that the sun orbits like the planets orbit because the suns orbit is what keeps our planets in their own particular orbits.🙂

The point around which the Sun orbits is inside the Sun but displaced from the actual centre. Hence see from outside the Sun does appear to ‘wobble’.

The point around which the sun orbits is sometimes inside the sun but it is also sometimes outside the sun too, so the sun is orbiting a point.🙂
