They are exploring multiple possibilities - one proposed explanation for the discrepancy is that light could take longer to travel as it red shifts and therefore our calculation of the big bang occurring 13.8 billion years ago would be drastically wrong (or something like that) I didn't read the paper but I've seen some videos on it. For all we know there could be matter outside of what the big bang birthed, if our model for galactic formation is correct it makes more sense to me that the "too old" galaxies discovered started forming before the big bang than the light slowing down thing

Thats what the media was saying, but they didn't understand what JW has found. Yes you are right that it found very old galaxies, but that doesn't mean the universe is older. There could be a number of things that caused that, for example that the universe was much much denser early on and formation of galaxies was accelerated because of that. The other thing could be that because space and time are tied, that in the early universe there was not as much space and therefore the speed of time was different, or is different relative to the expansion. Much like we describe wormholes now, folding space, but more like a rubber band. If you have 2 spots on a rubber band and then stretch it the 2 spots move apart. If a spot had moved when it was not stretched at a constant speed it would seem that when the rubber band gets stretched the spot is slowing down. We know that is true because we observe that with light and its called redshifting. And blueshifting in some cases. But if thats true for light it could also be true for other processes like the formation of galaxies and thats whats throwing everything off. Maybe.

How? If you mean by finding the galaxies that are too old, then there are a few explanations as to why. One is that you're right, and light slows down as it red-shifts (or something like that) meaning the universe is likely that 26 billion years old or whatever it was. Another is that our model of galaxy formation is faulty and those galaxies are being improperly judged and could've formed in such a short period of time.

The age of the universe is pretty nailed down. What this whole video is referring to is our models of galaxy formation. Our estimates for the age of the universe are not based on galaxy formation models, so as he said, one does not effect the other. From my understanding of what the paper they are referring to said is that if the model used in the paper is correct then it should take much longer for the early galaxies to form and match what we see. However, that just means there is a problem with the model they used. Other papers have come put that change some of the parameters (Including more high mass stars, etc) and it explains the data we are getting and matches up with how the early galaxies formed in the shortened timeline.

[@992ras]

Doppler effect on sound on earth doesn’t work in space but frequencies do. sound is nothing more then a frequency of molecules, sound is nothing but compressed air. Doppler effect on sound is why you hear sound in your left ear while the sound actually generated from the right side, Doppler effect has to take into account what is around that sound to change the sound and its frequencies. Also Lighting and the sound would fit into general relativity E=MC^2 the Energy and mass is the light at light speed times 2 the sound is the Energy and mass not at light speed so the light is two times as fast as the speed of sound. So if sound travels at rate of 1,000 miles per square foot that makes the lighting travel 2 times the speed. So if you divide that it takes half time for the light to travel the same distance as the sound does.

They are having trouble because they have removed God from their equations.

For comparison, the estimated number of SUB atomic particles in the entire universe is 1x10^256 (and that's on the high end of estimates). Some people think God doesn't exist because there is no proof, but they don't stop to think, That if He does exist, then He obviously has hidden Himself. Probably for a reason. A lesson maybe.

You can't insist, without offering any reason why, that the source of conflict between the observed properties of galaxies and your model of how they formed during the time since the big bang, can only be due to a fault in the understanding of how galaxies form and not in the time allotted, in which for them to form. I mean you can _say_ it, but it's not logical. Logic leaves both options on the table. Perhaps you have good reason to rule out option 2, but which you didn't have time to share. That's understandable. But to just throw such sloppy non-logic at the public, because we're not gonna get it anyway, as if we are pigs, is insulting. You should tell us the truth whether or not we'll understand it, as a sacred duty. Or leave science communication to someone willing. And that makes me want to point out, also, that Logic _also_ suggests that you don't know what the hell you're talking about, _in general_ if your largest model is making false predictions - such as of galaxies are forming 2x as fast as your model allows. And if that's the case, it's logical, by extrapolation to arrive at a a sense of _general_ dubiousness regarding EVERYTHIGN that you think you know. _You_ should arrive at that sense of dubiousness. I don't know why you and your fellows don't. This history of science is a cascade of generations of people who were extremely confident, and all quite wrong, as observed by each successive generation. Yet the confidence renews itself each time. I've never, in my life, encountered anything that makes it clear to me, that you know whether the universe is a thousand, 13 billion, 26 billion, or a zillion zillion zillion years old. It seems all a framework of presumptions, to me. For example, you measure the rate of something and extrapolate backwards. But how do you know that the rate is constant? How could you ever know that? No amount of not seeing it fluctuate can tell you that it doesn't fluctuate on a larger time frame with a high probability. When I look around at the small part of the universe _I_ can observe, all rates seem to fluctuate. Parsimony suggests, therefore, that rates fluctuate. What proof do your fellows have, therefore, that the constant rates they believe in, are indeed constant? How do you know that _time_ is even constant? Doesn't space-time bend in proximity to mass? And isn't space time quite possibly not even real, as I'm hearing from your fellows? It seems to be going the way of matter, God, free-will, gravity, and just about everything but taxes. And yet, you can sit there in supreme confidence telling us you're sure how much of 'a bent nothingness that might not exist except as illusion,' there has been between hypothetical event A, and the present. I wonder what could induce a wavering of such faith, if anything.

My question is, can we, especially using AI create a model of our earth and include all the data we possibly can… whether it’s satellites viewing earth in visible light and beyond, detecting chemical makeup and weather systems and sensors on ground, in air, and consider all available resources of potential information possible about our planet and then create a model including absolutely everything we can include (and i mean including everything such as solar system information, like orbits and asteroids and everything) utilizing AI to simulate an astonishingly accurate earth and spin that model forward a day? A week? A year? I understand we have models like this for weather and our solar system but can we do this to an insane degree? I can imagine AI being able to collect all available data that may contain information as to how things will unfold to a degree we can hardly imagine and put it on a model that constantly instantly updates (including seismic activity and absolutely everything) as to be able to severely increase our ability to basically see the future and plan for it? Because i really think we could very soon accumulate this data using ai in this way and quite seriously advance our capability. I can hardly think of any reason not to do this other than the possibility of revealing information they want us to not know. Seems like it’s probably the exact time we need to come clean about everything so as to be able to advance in many ways like this. And beyond that… if we create the absolute most accurate possible predictions of what “should” unfold in the coming hours and days and weeks… if reality unfolds differently than predicted… we could illuminate exactly what we do not yet know. About quite a lot, really… but especially variables that effect everything that we do not know about. So if our model predicts no hurricanes and yet we experience a hurricane… it could illuminate huge areas of science that could be established and investigated and studied and basically help revamp the whole of science, and i would honestly imagine that would basically catapult us into the future if we consistently revamp our models when we find the variables we don’t yet know. It would be a process to figure out what it could be… but the inspiration and motivation and etc would be inherent to the process. We could easily detect the holes in our understanding. And then initiate geniuses to figure out what theories could explain the difference. It could be a tipping point honestly.
