Re: James Webb Telescope Confirms That the Universe Is Expanding at Different Speeds
#52Earlier quoted context omitted.
The fact that you seem to be interested enough to email experts about ancient galaxies, yet still are referencing the big bang as an explosion, leaves me utterly confused about your level of knowledge, but leaning heavily towards "no idea what they are talking about". The big bang was not an explosion.
Oh I’m sorry on an open forum where I don’t know every reader I use casual language. This isn’t a forum for PhD defense. So glad the takeaway is about a single word. While the idea that researchers are failing left and right which reaches into everyone else’s lives is left untouched. Likely because you’re the sort that relies on people buying the con about your efforts. Reality is not a neatly organized set of decoup…
But the core of your post seemed to be an instance of how all the cosmologists are wrong because their description of the universe as it relates to the big bang is wrong because the big bang is an explosion and explosions don't expand uniformly. Am I misunderstanding your point?
Do you have, like, a list of things they're wrong about maybe?
Re: James Webb Telescope Confirms That the Universe Is Expanding at Different Speeds
#53I get that the universe can be expanding, and that there might be different methods to calculate/measure this that have discrepancies. But that the rate of expansion is accelerating , how in the world is that possible?
What makes you think that should not be possible? It's a pretty well accepted fact.
I think it is fair to find dark energy disturbing! It disturbs many cosmologists. It is very established empirically but we lack a good explanation.
Re: James Webb Telescope Confirms That the Universe Is Expanding at Different Speeds
#54Cosmology feels a lot like quackery these days. Does it even bother to rely on physics? Physical experiments show explosions do not propel all matter at the same rate. James Webb telescope recently found galaxies that were “too old”, would have formed right after the Big Bang. The prevailing wisdom was all matter spread out evenly due to the Big Bang, then coalesced into galaxies (I emailed various researchers to con…

Okay, then lets hear your interpretation of what it was.

#55This result has 8.3-sigma confidence, so it's as good as it can get statistically. Even greater confidence than that of the Hubble tension itself. The Hubble Tension is real. The expansion of universe is accelerating.
> The expansion of universe is accelerating. We knew that before. This goes deeper than that. It accelerates in a way that cannot be explained by a constant dark energy density, which is part of our standard model. We have plenty of alternative models that can explain this, but our measurements are not precise enough yet to rule any of them out. Hopefully Euclid will provide data that is.
I can explain it with higher dimensional turbulence. Where is my Nobel.

I don't want to discourage question-asking but you're now asking someone to give you a background on a physics phenomena without them knowing your starting level. It's awesome that the poster you're replying to introduced a new concept to us (not something I was thinking about, either) and literally taking the thing you quoted: "time does not flow the same everywhere" into Google will give you a starting point for yo…
Okay. I am a professional astronomer at the University of Washington, and I don’t see that phrase as holding very much meaning. In particular, “flow” is a messy word to use. A generous reading of the OP might be that it is a restatement of special relativity, but then it is indeed disconnected to this measurement. An uncharitable reading would be that it is spiritual goop. Anyway, I prefer to let someone answer in th…
Then I think a much better response to that poster would have been something "I assume you are talking about X but I don't see the connection"

The Big Bang has nothing to do with explosions
Please enlighten us.

It's in a box wrapped up in your peer-reviewed scientific papers
Re: James Webb Telescope Confirms That the Universe Is Expanding at Different Speeds
#60If the universe expands at different speeds, is it even possible to determine expansion relative to earth since you don’t have something fixed (since everything is at different speeds) to measure earths local expansion against?
