Chelsea, I really wanted to do this sad or not nice information opener for the week for our fringy mini
But it was behind a paywall. So unfortunately you ought to settle for a sciency one
Saved by a paywall. Maybe maybe we needed to know that information
I think we did but not everybody's going to agree with me on that
Maybe one day someone will send us some money to get behind the paywall
Yeah, it's that Wall Street Journal paywall. So I don't think we want to never mind
Whoever was opening the app to send us some money. Let's hear the are you gonna still send us the money, please? Okay
We could use the money
Chelsea this one I found interesting it might not be that interesting
But there's a few things that we kind of think we know about the universe one of those things the big bang happened 13 billion years ago
Yes, here's an article from fizz.org
Published by Bernard risk of the University of Ottawa on July 13th, 2023 new research puts the age of the universe at
26.7 billion years nearly twice as old as previously believed our universe could be twice as old as current estimates according to a new study that
challenges the dominant cosmological model and sheds new light on the so-called impossible early galaxy problem
Which we talked about in a early episode
So this one's a bit of a follow-up on that the work is published in the journal monthly notices of the Royal Astronomical Society
Our newly devised model stretches the galaxy formation time by several billion years making the universe
26.7 billion years and not 13.7 as previously estimated says author
Rahandra Gupta adjunct professor of physics in the faculty of science the University of Ottawa for years
astronomers and physicists have calculated the age of our universe by measuring the time elapsed into the big bang and by studying the
oldest stars based on redshift of light coming from the distant galaxies in
2021 thanks to new techniques and advances in technology the age of our universe was thus estimated at
13.797 billion years old using the lambda CDM concordance model
however many scientists have been puzzled by the existence of stars like
Methuselah that appear to be older than the estimated age of our universe and by the discovery of early galaxies in an advanced state of
Evolution made possible by the James Webb's base telescope these galaxies existing a mere 300 million years or so after the big bang
Appears to have a level of majority in mass typically associated with billions of years of cosmic evolution
Furthermore, they are surprisingly small in size adding another layer of mystery to the equation
Zwicky's tired light theory proposes that the redshift of light from distant galaxies is due to the gradual lost energy by photons over vast
cosmic distances
However, it was seen to conflict with the observation yet Gupta found that by allowing the theory to coexist with the expanding universe
It becomes possible to reinterpret the redshift as a hybrid phenomenon rather than purely due to expansion in addition
Zwicky's tired light theory Gupta introduces the idea of evolving coupling constants as hypothesized by Paul Dirich
Coupling constants are fundamental physical constants that govern the interaction between particles according to Dirich
These constants might have varied over time by allowing them to evolve the time frame for the formation of early galaxies observed by the James Webb
Telescope at high redshift can be extended from a few hundred million years to several billion years
This provides a more feasible explanation for the advanced level of development and mass observed in these ancient galaxies
Moreover, Gupta suggests that the traditional interpretation of the cosmological constant which represents dark energy
Responsible for the accelerating expanse of the universe needs revision instead
He proposed a concept that accounts for the evolution of the coupling constants its modification in the cosmological model helps address the puzzles of small
Galaxy sizes observed in the early universe allowing for more accurate
Observation so that's the article Chelsea. What do you think anything to say on it? Not really
I mean, it's all really cool things that we're starting to find out about the universe
It seems like everything I grew up knowing is all wrong and it's all new and shiny now all the time
But it's not ever really anything that I completely understand
No, but every time we get a better way of measuring we find out how we're fundamentally understanding it or might not be correct
And there's two things that we really don't understand and we just call them dark matter and dark energy
And this does seem to somewhat take away the problem of dark energy the thing that we just can't measure
So that's a cool thing that means we kind of understand a bit more of the universe
But I always like to quote we pretty much understand everything except the really big and the really small and the really hot and the really cold and
Pretty much everything. Yeah, that's a good way to put it
Yeah, just a new proposal out there fundamentally changing and answering the question of these old galaxies
So following up to that one intro that we did and I can't remember which episode but that's okay because these are for in
Jimini's now. Yeah, enjoy. Tell us anything else to add. No. Well, I hope you all have fun reveling in the
Infantissimal size of your existence in this universe and they start to our Wednesday while you cope with that
We'll see you on Friday. Bye.
