Thank you for this kind offer.
Red-shift is the key weakness. From various explanations and documents I've seen in recent years, there are too many observations that defy the presumption that red-shift indicates distance. Objects that are very close together may have very different values, and in some cases the "farther" object is nearer than the "nearer" object.
The bolded words are where I see red flags (pardon the pun) raising, and not verified facts.
Sure, and I included the bolded words so that you can see exactly where in the process you might have doubts.
I need to clarify that, other than at extreme redshift values, redshift is not used to
determine distance. Otherwise your own statement wouldn't make sense: "the object with higher redshift is nearer than the object with the lower redshift"? I hope you'll agree with me that you can't meaningfully say that unless you have some independent, non-redshift way of measuring the distance.
What happens, rather, is that astronomers measured the distance to celestial objects, and then independently measured the redshift, and found that in most cases they were linearly correlated - Hubble's Law. But if you have any evidence that shows that they aren't, such as those cases you're talking about with a high-z source in front of a low-z source, I'm very interested to look at them.
(It should also be noted that in recent years the importance of red-shift as evidence for the Big Bang has been overtaken by the cosmic microwave background, of which we now have very good measurements using satellite microwave telescopes. But we'll settle one thing at a time.)
Thank you for this clarification on steady-state. But it too depends upon the presumption, not proof, that red-shift indicates a Doppler-type effect. If it doesn't, both of these choices are wrong, and thus it amounts to a false dilemma. So I remain unconvinced that stuff is flying away at all.
Yes, that's right - if you believe in intrinsic redshift, then you can reject both standard Big Bang cosmology and standard steady state cosmology.
But steady-state according to your statement raises another question: If it has always been flying apart, how old can the universe be? To eternally be flying apart means it was once very tightly packed, and then we're back at the Big Bang because both theories are not steady at all but always in flux. In other words, I see a hopeless contradiction between "steady" and "always changing". So if this definition of steady-state is accurate, it is self-contradictory. Rather, it would seem reasonable to state that if the universe has always been "steady", it has always been where it is now instead of expanding.
Thank you for pointing out problems no matter whose theory it might be; I hope to have done the same with the theory that anything which is expanding can be called "steady state".
As I've said, the standard (Hoyle's) steady state model imagines a universe where new matter is continually being created throughout empty space. This resolves the problem since you can get both stuff flying outwards continually,
and the density of matter remaining constant - meaning to say that density doesn't decrease running forwards in time, and also that it doesn't increase running backwards in time, and therefore there is no singularity and so no Big Bang.
Note that Halton Arp's cosmology has continuous matter creation, which puts it squarely in this family of cosmologies (which, you must remember, were originally thought up by astronomers with an
a priori bias against any kind of beginning in time for the universe, which would imply a creation). Also note that the Electric Universe, if I recall correctly, does
not have continuous matter creation - and so you can't have both at the same time.
Again, I think we have a false dilemma here, but can you explain why a redshift source that has nothing to do with motion depends upon GR?
Simply because GR
gives you the mathematics that tells you, given a certain redshift, how fast this redshifted object is going. If that relationship is wrong, then GR is wrong.
I have never seen any kind of intrinsic redshift theory that was content to let GR be, and it makes sense: if you were happy with GR, you'd be happy with the Big Bang, and you wouldn't have any reason to introduce an intrinsic redshift.
And you raise a good point: is GR airtight, especially when we know that even astronomy has its "sacred cows" and will indeed cover up or marginalize any data that might throw careers into the trash bin? The fear of having to return to the drawing board certainly can result in scientists clinging desperately to theories that are being called into question due to further observations which don't fit and even disprove them. I rather welcome the prospect of admitting we really don't have cosmology all sown up, and should be led by the data instead of force-fitting it into theory.
Let me ask you two questions. Firstly, when have we ever seen any other science behave like this? The case of Newtonian physics vs quantum physics comes to mind. When evidence began to show that the old physics wasn't good enough, physicists were floundering around for a better explanation. Einstein told God not to play dice. Schrodinger (if I recall) spent long nights walking around parks wondering how the universe could be so cruel. Bohr said if you're not deeply disturbed, you don't get it. But not once did any of the scientists decide
"Let's make sure nobody ever sees a blackbody spectrum again." Plenty of evidence nobody could understand: none of it was covered up.
Indeed, Bohr subsequently fought hard to champion the new physics, and Einstein fought hard against it. We remember them both as legendary physicists: which only goes to show that your career won't get thrown into the trash bin just because you support new science, or don't support new science. (Einstein's lesser-known colleagues Podolsky and Rosen also became well-known for working together on the EPR paradox, too, so this doesn't just apply to people who had strong reputations to start with.)
Don't confuse this with the well-known (and unfortunate) fact that non-standard cosmologies don't get enough telescope time. People like Halton Arp keep complaining about being shut out of major institutes: they conveniently forget that about 80% of experimental proposals from
standard cosmology are also rejected. We simply don't have enough telescopes to go around, and we'll have even less telescopes if after five years of free rein with the Hubble telescope Arp decides "I was completely off-base after all, sorry folks, now who was next in line?". But this could all be solved in a very simple way: get the creationist folks with the deep pockets to just
build a telescope complex for non-standard cosmology. Then they'd get all the telescope time they wanted. (The fact that they'd rather build a dino museum and a faux ark tells you where their true priorities lie, by the way.)
But from a theoretical point of view, there's no problem with believing that the universe is made of plasma, or rubber duckies all the way down for that matter. You just need the evidence for it. Of course, if you don't have evidence, you can invoke the invisible cabal of evil scientists somewhere in the dark destroying any data that goes against their theories. But think about that for a second: couldn't we invoke that cabal
anywhere? (That's my second question.)
So let's say I believe that GM corn is secretly being doused with hallucinogens to make the American populace docile enough for a socialist takeover. Why don't I have any evidence for it? Blame the invisible evidence-destroying cabal! Or let's say I believe that the early church deliberately suppressed gnostic interpretations of Jesus' life in producing the New Testament we have today. Why don't I have any evidence for it? Blame the invisible evidence-destroying cabal! The Holocaust never happened, the Holocaust really happened, the CIA caused 9-11, Al-Qaeda caused 9-11, we walked on the Moon, we never walked on the Moon, the Earth is round, the Earth is flat, the Moon is billions of years old, the Moon is made out of green cheese - all I need to do is to attach the invisible evidence-destroying cabal, and I instantly have a position which is obviously correct and couldn't possibly be wrong.
Now I happen to believe
both that GR has worked really well
and that we really don't have cosmology all sown up. And if you're interested, I'll present you all the evidence we have on hand that demonstrates just that. But let's get the invisible evidence-destroying cabal out of the way first.
The EU model shows good potential for being a much better predictor of observed astronomical phenomena, as well as working even at the subatomic level; this problem of scale is a very big thorn in the side of conventional physics, which (it's my understanding) requires two inherently conflicting theories to cover the very large and the very small. With EU, the cosmos can stay or move without a sweat.
That gets us into the evidence, and as I've said above, I'd like to be able to deal with the evidence without the specter of an invisible evidence-destroying cabal in the background.
But none of these theories deal with how anything at all came into existence. If we know (by observation) that physical things run down, we know that they cannot be eternal. Philosophically we know that nothing could possibly cause its own existence. And so I still must conclude that some non-physical and eternal entity is the First Cause. Thus there is no conflict with the Genesis account of creation, regardless of the span of time people assign to it.
But Genesis 1 doesn't go "A First Cause caused the universe"; it says "In the beginning", which clearly implies a temporal beginning for the universe, not simply some nebulous causal relation to God. Now if you want to make even the first three words of the Bible non-literal, be my guest; but then why not go the whole way and understand the rest of Genesis 1-11 non-literally as well?
