Has JWST SOLVED the crisis in cosmology?!

OMG, thank you PBS SpaceTime and Anton Petrov for introducing me to Dr. Becky. I love this type of content as a extreme layperson. Slay...Xlay?

The problem with our view of the universe is that there is a horizon that we can't see beyond. There could be entirely different things happening beyond our view. It's like we're on an island in the middle of the ocean and have no idea what the rest of the world is doing.

All science is science fiction.reality exist in the human mind and nowhere else

No offense,there is no physical universe.

Fascinating stuff. However, them blue eyes! 😍

Do the brightness measurements of Cepheid Variables take into account dimming by interstellar material ?

Any update on this?

Carl Sagan is your Messiah! waste much money prove flat universe theories; no new Columbus on tv

This is a great explanation of how distances to distant objects is determined. Thank you. What I still need to understand is how that determines expansion rate. If expansion rate is determined by only red shift of objects of known distance, is anyone questioning red shift itself? Is it possible that the universe is static or shrinking (as might be intuited by us non-physicists) and that the red shift is not due to objects moving away from us, but some other property of light and great distance that we haven’t pinned down yet? (Tired light?) Expansion and acceleration run counter to the amount of observable matter, in addition to giving rise to the cosmological crisis. Quantum physics was such a huge, unexpected discovery that I wonder if there is another one concerning super macro physics yet to be discovered. One that might make a static or contracting universe the better theory. It’s hard to know what we don’t know, but it sometimes seems the scientists are not using their imaginations.

I figured it was something simple. I hoped it was something crazy.

This is the best discussion of the cosmological distance ladder and the Hubble Constant I've experienced. Thank you for your detailed explanations and also thanks to your graphics team (or whoever helps with the graphics) - super good effort!

So now we have three mostly disagreeing measurements instead of two. And the "middle distance" measurements are in the middle. I'd say this makes things worse as far as trying to explain things as just measurement error.

Well, I am pleased to hear that analyses with a varying expansion were considered. This aligns well with the Original Cyclic Cosmology, but I'm not sure whether it excludes the other (existing, sigh) Cosmological models.

At least we can say the results "when 2of3gods are replaced w1" are GOOD!! 🎉😊

Sorry but even if it's a burning subject. You decided to make a video on it and when you try to justify it, it's even worse.

Awesome content. Very informative and understandable. You rock, Dr. Becky! Look forward to more of your videos!

Even on this preliminary finding, I'd hesitate to say that JWST has finally solved the tension, but I'm not a member of the field or anything so I don't know much. Just looking at the confidence intervals, Freedman et al.'s 69.1 +/- 1.3 is barely not significantly different from the Planck 67.4 +/- 0.5, the lower bound on Freedman's avg expansion rate would be 67.8 and the upper bound of the Planck avg expansion rate would be 67.9. Given that JWST has a 7x lower rate of measurement error, a larger sample size of JWST might make that significant difference re-appear if the average JWST expansion rate stays the same and the standard error decreases

Whats God actually do ?

Dr. Becky is talking about all the effort scientists go to avoid biases - the on-blinding...:)

And yet, Dr. Becky refuses to even learn about the MOTHER OF ALL BIASES... the bias scientists have against stuff created by someone who is not their peers. I don’t review her grants or papers, and because of that, I get no respect…:)

I am not a Cosmologist... that said, I have more education than the best Cosmologists.
So, the model I offered free of charge to scientists is the one where G is inversely proportional to the 4D radius of the Universe. You might ask, isn't that supported by General Relativity? The answer is yes.


So, I also provided FORCES that replicate all Einstein's observations (Mercury Perihelion Precession Rate, Gravitational Lensing, Frame Dragging, Binary Pulsar Frequency decay, etc.)

It also showed that Einstein's theory was wrong and that he made gross mistakes in his derivations.

Of course, I also eliminated the Hubble Tension. I showed that the Absolute Luminosity of SN1a has a G^{-3.33} dependence (they detonate at Chandrashekar mass limit, and that has a G^{-3/2}. My Hubble constant is the same for all redshifts, and it is 69.69 km/(s.Mpc).

So, I am no "Einstein". I am the fellow who corrected Einstein, just in case.

I replicated the CMB observation using Hypergeometrical Harmonics and found the location of Earth.
In the process, I created a 3D map of the observable universe, including the CMB.
and explained the CMB modeling in terms of two processes. The first is due to Neutroniuam Acoustic Oscillations, triggered when the Blackholium phase transitioned into Neutronium. The second happened when the Neutronium evaporated, releasing free neutrons and energy.
In other words, the Universe started as a Zero Kelvin Blackholium (hyperspherically shaped black hole). Only at the end of the first day, the Neutronium began to evaporate, and the universe got hot.

You might say: How could scientists miss those mistakes?
They only look at their belly button... very narcissistic.

Thanks for your amazing teaching!

Why don’t we figure out the milky way first…not bodies so far away it’s of no relevance to us in the next 200-300 years?

Hi, please comment on the little Hubble Constant "fixing" geometry based equation 2 X one Mpc X C, divided by Pi to the power of 21 = 71k/s/Mpc. Regards, David Hine

The crisis hasn't been solved even if the result is as advertised. The question remains, 'Why do the earlier measuremenmts disagree?' A number of ideas have been offered to explain the difference. The error bars on the new result are too large to help with that.

So, the value of Ho could well be 69?

So if this passes peer review then that means that Dark Energy is not a thing?

Dr. Becky spent too much time apologizing for reporting cutting edge research. Don't! Just mention a quick disclaimer, and if it ends up all wrong, simply delete the video. You don't need CYA if you can delete your A when it fails.

What if time is the constant instead of the speed of light? The tools we use do not measure the speed of light accurately. If there had been a big bang what became us would have been created by it. It is not possible for the light to take billions of years to get to us. Just because we see distant objects as they were billions of years ago doesn't mean they were created closer to the beginning of the universe because the universe is eternal. Universal expansion is nonsense. If distant matter all came from the same place how could it take up so much more spacial volume the longer ago we see it. The big bang theory makes so little sense that is is even very difficult to even try to describe it. The fact that we can detect microwaves prove nothing. Of course we will detect radiance from every direction. Scientific endeavors make basic assumptions without proper regard to their influence on resulting conclusions. For example Einstein concluded that it would take infinite energy to travel at the speed of light. What experimental evidence did he have for this? Look at how many things that have proposed by science fiction writers that scientists try to prove. The so called multiverse is just one example of that nonsense. The universe I live in is eternal, boundless and doesn't expand.

Nothing has been solved, all hype. The model of The Universe is beyond wrong and PhD's literally can not cope, grasping at straws like insane people.😅

Imagine....
We’re all here, just because of a ‘black hole’
We’re actually the result of a massive dying star....we’re on the ‘inside’ we’re not expanding just experiencing the effects of space time evolution...just a thought...
Given what we ‘know’ we’ve still absolutely no idea how it all began...we can theorise but cannot be absolutely definite....which makes research so important...
It’s Weird that a religious campus would fund research for these investigations....unless there’s an ulterior motive...

Text book confirmation bias.

Fuuuny! Thanks for the out takes, and the update :)

Great review

Get excited lady

Does the rate of expansion of the universe have any practical effect on our understanding and development of the physics that regulates the development of new technologies? Direct effects, not ancillary or corollary, because there could be unanswered questions of existential recourse within other scientific fields of study rite here on Earth. I can hear your gasping for breath now, and I will accept all of your invectives on my very soul. I'm just as interested in the rate of the universes' expansion as you are, I just feel that we haven't discovered our own rate of historical expansion here on Earth, to a significant amount of accuracy. And the effects of this ignorance on our understanding of all things considered is incredibly important to us all. It most likely will have a determinative effect on the calculations that will accurately define the rate of expansion of the universe, too.
Be kind and do good work.

Space isn't expanding evenly. Duh, problem solved. . 😊

What crisis? Science is about discovering the truth, not pathological devotion to dogma.

Sounds like we are so far off on our guessing math that we are just assuming more with few known facts of physics that only apply to us in our narrow understanding of time and space. If time is moving at a different rate due to gravity or speed of light but we put our equations as a one size fits all. It just doesn’t seem to make sense to me.. What I am getting at is that we are measuring red shift as it applies to our observation thinking that the red shift is all the same as our observed time. Yet how do we know if time is moving at a different rate due to gravity in a different area causing more red shift? Just asking?

Yes it has solved the crisis! JWST has just provided more than ample data to refute the pre copernican Big Bang theory. Looks like JWST just gave us data that only fits an infinite age and sized non expanding universe. Although its ridiculous reading to read the contortions of logic Big Bangers go through to pretend that all their predictions made pre JWST have been soundly refuted by all the subsequent JWST data.

Dr.Becky, I just want to thank you for the information you provide us and how detailed the information you give is. I Love all things space and how defined the information is given. That is the main point of me Subscribing to yuo my friend,.

Not only are you Beautiful, But you have an Absolutely beautiful Scientific mind!

I apologize if i seem creepy with my comments and the viewing of your uploads but it's true. I really think your thoughts are sensible and make absolute sense. If you find me creepy I apologize. with all the false and predicted theories that are out there...Yours seems the most nearest hypothesizes are the best and closest to reality. And Dr. Becky, I appreciate your intelligence .

Me: This is so exciting, the resolution in the expansion rate of universe may help us understand the early massive galaxies being found by JWST.
Also me: So the universe is expanding at a rate of 69 km/s/Mpsc(+/- error), Nice!
Thanks a lot Dr. Smethurst for this helpful and informative analysis.

To even suggest we have all of the laws of the universe figured out is so incredibly arrogant. We are just beginning to understand so many things. We are infantile beings at best.

We will never have reliable measurements because God is making it impossible to know the true nature of the cosmos. 💡

What I wanna know is, does this predict a big rip, steady state, or a big crunch? 🤔
