I agree, but my point is that the concept of an infinite universe is entertained in pretty much all cosmology models.
Infinite in the hypothetical sense, not something we could remotely observe scientifically, because it would, by definition, never end
Actually, it don't personally care if it's finite or infinite. I fail to see how it cold be "time limited" however since energy cannot be created nor destroyed according to the laws of physics, so something has necessarily *always* existed, and some arrangement of energy will always exist.
Time and space can be said to be linked, but at the same time, we have the notion that time slows down the closer to the speed of light one gets, with general relativity
I'm just pointing out that redshift is the only thing that we actually we "observe". The cause of that redshift is debatable. Edwin Hubble is usually credited with discovering that we live in a universe full of galaxies and not just in one island galaxy universe. He's also usually credited with the expansion model, but by the end of his career he was pretty sure that redshift was related to tired light rather than expansion, and Zwicky is credited with the tired light concept.
Explaining in simpler factors rather than considering that the universe's scale is not something the works on the same principles as a smaller system is the problem. We can't observe the universe in itself, only as we have context within it.
Sure. The fact that we no longer assume that the Earth is the center of the universe today would suggest that change is inevitable. I don't object to change, but I do tend to object to simply adding supernatural elements, one after another after another.
The idea of the eternal universe seems a means to just have "God" as an "explanation" in regards to the stuff outside of scientific limits, but be satisfied with a universe that violates principles already established to satisfy some notion of energy and matter being conserved by recycling (as if recycling is completely energy free in its process as we understand it in terms of materials)
I tend to agree with that as well, but I prefer to try to explain what I can explain with empirical laboratory physics when possible, but of course scaling will always be required in cosmology.
Laboratory physics are necessarily impossible to apply entirely with cosmological scales, because it still exists within the universe anyway, rather than seeing the universe at a distance for the lab studies
That's possible of course, but I don't really have any empirical evidence that gravity really changes all that much simply based on scaling. About the only thing that does seem to change is the *amount* of gravity and the amount of mass.
I'm talking about the black holes and such, something that creates questions in regards to gravity's effects on a galactic scale, such that supposedly, at least from some observations or such, our galaxy may be gravitating to another galaxy in a few billion years.
Maybe not, but the whole dark energy proposition was mostly based on a very limited SN1a data set, and a small number of studies. The papers I cited are much more recent and they involve many times the number of SN1A events.
Multiple experiments based on flawed methodology or limited scales does not make one premise more compelling, we're still talking about your incredulity for one explanation as a cause when yours brings up more questions than it supposedly answers (recycling of matter as some notion of "conservation" and the notion of a static universe that nonetheless changes, contradictory in nature)
No you didn't, but most astronomers assume that is the case, particularly at larger scales. That's why and how we ended up with exotic matter theories and exotic energy theories. If one presumes that EM fields are involved the movement patterns of the universe at larger scales too, exotic matter and energy are no longer necessary to explain what we observe in space.
The EM fields may not be sufficient in terms of the scale if we're talking about a universe we don't know about the beginning of beyond particular observations that have a limit (a singularity, event horizon, etc)
Actually, we can look back in time in astronomy as we look at distant objects. We can also build computer models to simulate the passage of time and to scale things appropriately. We can also test the core "cause/effect" claims in the lab in some models. Those kinds of models tend to be more "likely" to be correct IMO. Models based on many assumed causes tend to turn me off.
We can observe based on particular measurements, but that's not the same as literally going back in time and space, at best you're referring to forensic observations by measuring cosmic radiation, etc (like how some stars may very well be dying)
We necessarily have to assume certain things when the evidence doesn't lend itself to a simple explanation due to problems of scale, etc. Assuming things always function the same regardless of space or time is faulty reasoning in science, because our notions of consistency are limited in application the further removed we are from the object of observation
Actually, I'd say that a large SN1A study that arrives at a different conclusion tends to undermines the whole concept since SN1A events were the entire basis of the original claim. If one simply moves the goalposts when the data doesn't support the idea anymore, it becomes "dogma", not science.
And if one just shifts the goalposts to needlessly narrow, that's no better, science is not about such precision that it stifles innovation anymore than being open to just anything, it's a moderation between them
It's that "practical application' part that causes me to embrace evolutionary theory as well as EU/PC theory. Exotic energy and exotic matter concepts don't seem to have any "practical value", they're primarily used simply to prop up one otherwise falsified cosmology model.
When one literally can't go beyond a certain point in observation, the exotic energy is a placeholder, it's not meant to be anything absolutely conclusive, it's more that the static universe is ignoring other aspects by trying to needlessly constrain what constitutes science when the scale is galactic
I think the entropy concept seems to be misused more than it's used correctly. Systems, including solar systems can become more 'organized' over time due to gravity, and become less organized too due to fusion.
Organized in a loose sense, but when you're talking a closed system on the universe's scale, it's not likely it will always lend itself to such scenarios: plus the "fusion" you reference is a particular form, it's not as if one is claiming gravity always leads to entropy and fusion always leads to order, science acknowledges contextual variation of terms and applications of forces based on those contexts.
Black holes, an observed phenomenon, suggest one aspect of gravity, but fusion also creates a similar destructive aspect that then supposedly leads to the black hole, so it's more a matter of immense mass and gravity potentially collapsing the object onto itself or the like
So what prevents someone from inventing any number of supernatural elements on a whim?
Up until the Big Bang theory, and Hubble, it was assumed we lived in a single island universe that was relatively static. I simply prefer to explain what I can in the universe with ordinary empirical physics and just admit that I can't explain it if I can't explain it with basic physics. I don't see any great value in simply 'making stuff up" and pretending that I've offered an "explanation' when I really haven't. Dark energy and matter aren't actually "explanations", they're simply placeholder terms for human ignorance. I'd rather just admit that I simply can't explain some types of observations via empirical physics and leave it at that. Fortunately it's possible to explain virtually everything in space with empirical physics
An explanation based on a naturalistic methodology is being far more honest that saying you don't know when you're more likely substituting an unfalsifiable agency in terms of matter and energy's origin that then leads to an eternal universe
Funny you say "virtually" because that's necessarily the case when you admit there are constraints. Ignorance is not an excuse to stop thinking or go with what "makes sense", neither of those are scientific virtues in the slightest
