At 07:41 I said “ISRO” not Isreal, as many of you seemed to hear. ISRO is the Indian Space Research Organisation. You say the acronym as a word, like you would with e.g. NASA and ESA
To be honest, I don't understand most of what you discuss but with your help I`m slowly getting there and the bits I can understand I find absolutely fascinating. Thank you Dr Becky, love your channel and take care
I still get sad that the milky way isn't anywhere as visible was when I was a kid. Aged about 5, I remember seeing the milky way on my way home and it was a spiritual experience. It's why I'm still interested 54 years later. Great content Dr Becky, I'm an addict to your channel.
@DavidCruz-dv2ot I'm in the UK and it's pretty bad here, you have to go to a designated dark sky area to see things properly. There are some good places, but it's not like when I was a kid, I saw the Milky Way in Liverpool, one of the largest UK cities.
@@naomimoore47 I know what you mean . I grew up in Sydney Australia, 7 km from the city centre , which now has a population of 6 million and the Milky Way is barely visible . In those days 50 years ago , the lighting was much narrower bandwidth ( not LED ) and the city centre would be vacated on weekends , and business districts shut down after 6pm weekdays . I still l have vivid memories of the Southern Milky Way overhead in the late hours , complete with dark dust lanes . I sometimes used to lay on a blanket watching the Milky Way and looking for shooting stars . Its all gone now in just 1.5 generations .
No, I don't watch this channel for the bloopers, BUT they do provide a way of unwinding from the wonderful amount of detail found in each episode. Yes, they are entertaining.
Everyone is always saying for the red/blue shift it being based on the speed of the galaxy but shouldn't it be a bit more complicated as during travel the space expands and accelerates and whatnot, how to take that into account mathematically?
Doesn't this just show that our current models are fundamentally flawed, which isn't all that surprising, because it's consistent with other discoveries from JWST that prompted to rediscuss a lot of previous assumptions?
I'm curious how we would be able to tell how much water on Earth, if any, came from impactors. In the event that the Indian lander does find water there, wouldn't any indicators be long gone for them having a "common" source? Between the natural functions of our biosphere and any water on the moon being exposed to increased levels of radiation, wouldn't it be impossible to tell by now? It will also depend on how lunar impactors carried ice and how many of those carried large quantities, wouldn't it? Just finding ice is far from enough to say that any, significant, amount of water is extraplanetary.
weird choice to take Betterhelp as a sponsor, when they shared extremely person data with third parties like facebook, WITHOUT consent from the patients. I would avoid mixing my name with shady companies in your place.
As an amateur astronomer it is fun that someone with your education takes the time to promote the night sky. I have been involved in public star parties for over 20 years.
As a person who just watches videos about space science stuff it is fun for me too. I don't have a telescope and am rarely outside at night, but still nice to find out what other people know and are finding out about it. Pretty sure that if/when ET lands I'll only find out about it on RUclips.
Thank you Dr. Becky for explaining the hexagonal shapes left by repeated drying periods! You make learning so fun, and yes, I always watch to the end. Always! ✨
Right that was super interesting, like I recognized the phenomena instinctually but the details of it and mechanics being explained was totally new and interesting.
I’m another who listens all the way to the end. And I really enjoyed your audiobook narration. Dad worked on ranging systems for the Deep Space Network, so I grew up to relaxed conversations with him and the parents of friends at JPL and Caltech, talking with us or each other about technical subjects but without the pressures of workplace formality. Listening to you felt a lot like that, giving me happy old memories as well as present satisfaction. Thanks!
...And perhaps never. In my previous comment I was thinking of cats in space suits...but now am thinking that claws are a contraindication to pressurized space suits.
You and Anton Petrov are the two people I'm following and watching for atrophysics and astronomy news and explanations on these new discoveries and their implications. Tremendous work from both of you, and as he says : stay wonderful !
I've a wonderful/not so wonderful parasocial relationship with Anton; me love him long time 👄 (sorry, hadn't used that emoji ye- err, not sorry, looks great!), so I've learned a lot, the guy uploads every friggin day 👑, truly he's inspiring.. amazing in some ways.. however, I don't believe he's beyond reproach &'m certainly familiar, familiar?. shit, I'm living your sentiment & there are times (like literal chunks of a year) I can't even listen to him. It's nice to be validated, eh? 😏 But wait, there's more (no damn Oxiclean emoji though 😕 Kudos for spilling unpopular opinion; scientific communication needs more discourse, spruced a bit with the philosophical, & dammit, have a sense of humor, people.. as a species, we're Apex Ape & outta laugh a little. 🥧😢
Interesting to note, even though Chandrayan 2 lander had crashed, the orbiter of that mission is still functional and communicated with the new Chandrayan 3 lander. That's some nice way to save money haha. FYI Chandrayan3 did NOT land on the South Pole, not even what's considered polar region. Nor does ISRO said it landed on South Pole, It's the Indian Press that added Masala on the news for views. They did the same with Mars orbiter mission calling it Mangalyaan. NASA general knowledge webpages got fooled too for some time
Watching to the end endears you to us your followers. And you try so hard to keep explanations simple, educational and entertaining. I for one appreciate your spirit! Cheers.
Like the "Ultraviolet Catastrophe", the "Crisis In Cosmology" almost certainly reveals a fundamental lacuna in our current understanding of Physics and Cosmology.
I saw your comment directly after posting mine (herewith), thunked my sentiment was to be a lonely one. 👍 - I'll not watch this episode on principle (clickbait does not a view make,). - Neither will I contest this definition of crisis; such is squarely within semantic boundaries [κρίσις/krísis (Greek): distinguishing/separating-personally, I implement it as "turning point"]. I will, however, question its deployment: ad hoc hype (viz. viewership,) brandished rather blatantly. I thought better of Dr. Becky (and other science communicators).. unfortunately, my hope for a better future is whittled a little each day by the very idols claiming to keep them. 😔
We are talking about a 9.5% discrepancy. We may learn something new, but it will not be "catastrophic". If you are looking for a blockbuster, explain dark matter.
Welp, what a difference 2 hours makes; I no longer interpret the above comment the same way I did before.. as such, I don't think my comment belongs her but I'll leave it (at least for now) as I still feel the same except I'm reconsidering watching the video, curious to see how she handled it.
@@nyrdybyrd1702 I love smart people! You strike me as hyper-intellectualized. I'll save you a lot of stress (but you probably know this already): the fundamental problem is CAPITALISM. One cannot (click) bait where there are no (swedish) fish. A more interesting question is: what do you think of Lee Smolins characterization of quantum mechanics as "incomplete?" He argues that the three axioms that govern QM (e.g. Born Rule...) are fundamentally inconsistent conceptually and as such we need a conceptual re-thinking of QM that reproduces the same math but under internally consistent conceptual conditions. He, astutely I might add, cites Ptolemys epicycles to aid his thesis. He argues that the math in Ptolemys Epicycles was actually very accurate, but it was conceptually incorrect even though the underlying mathematics was generally right - or close enough to right. Just curious what your thoughts on that were.
You're doing a marvelous job, Dr. Becky. I always look forward to your coverage of all things galactic and beyond. Thank you so much for the hard work you clearly put in.
I still think the solution to the crisis in cosmology is that the CMBR is from when the universe was in early access, before all the physics bugs were fixed. QA wanted to reset and have a new big bang, but the business people said nobody was around to notice and it was too late by the time the devs pointed out that there would always be leftover light traveling through the universe.
Looking around the sections of the app we can see, I suspect we are still only in early beta testing, the local variables seem to make sense but the global variables are still confusing.
@@uglybob7505 It's nice to see a kindly sarcastic response. Obviously humorous and not mean spirited. Think you might be someone I'd like to have a beer 🍺 with!!! Again sir have a great day 👍.
@@joec-hd6dc Hey Joe. Aye people take things too seriously on YT...nice to have a giggle and share views without people diving off the deep end. Take care buddy 🙂
It’s still up to people to interpret data. All JWST does is collect it. People interpret it. Looking into space with night vision goggles at objects normally only seen by Hubble. Still doesn’t have a tag or time stamp as to what ones looking at.
I don't get the panic. The age of the universe and expansion rates were based on poor data, personally I expected a change. Question is why the surprise? Your models were wrong haha!
yes, but the problem we have had for the last 70 years is that if your Peer-Reviewd (yet unapproved/published) paper rocks the academic boat too much it will be rejected and then all the scientific papers you have in the scientific journals are just rehashes of existing papers with different spins on the titles you get very little progress. Old men will go to extraordinary lengths to protect their work - even if they were wrong.
@@off6848, science isn't wrong, the old guys who hold onto their 30-50 year-old theses are wrong; scientists question those assumptions, they just don't get published in peer-reviewed journals. So all scientists have to do it outlive those old guys... (Okay, it's way more complicated than that...)
Thank you so much, for your videos. You are very relatable and seem down to earth. I’ve been trying to get my granddaughter (she’s a very bright 11 year old) interested in the sciences, especially astrophysics, or any related subjects to light that spark in her that will ‘ nudge’ her to seek a beeper understanding of our world.
The excitement someone shows with the possibility of brand new science shows you just how much a scientist likes their job. Dr. Becky LOVES her job, you can tell! I'm just a science fan, not a degree in sight attached to my name, but even I get happy when new science is found, and it doesn't seem like it'll be long before some new science is found, one way or another, in this puzzle - and I'm ready for it! •~•~•~•~•~•~•~•~•~•~•~•~• On a separate subject: Everyone, please take time to tell those dear to you you love them EVERY chance you get.

6:23. Becky, please understand that the Chadrayaan-3 lander DID *NOT* LAND AT THE LUNAR SOUTH POLE!!! It touched down in a gently rolling area at latitude 69.37 degrees south, which is 625 km NORTH of the south lunar pole and not at the pole itself. Saying that it landed at the pole would be about like saying that the far northern coastal village of Tuktoyaktuk, Canada is at the Earth's north pole, which it clearly isn't. We have deliberately crashed some probes fairly near the south pole, but no one has yet soft landed very close to it. Also, the moon is too small to act as much of a shield for the Earth during the heavy bombardment period. The reason the southern highlands appear so heavily cratered is that they are not covered by the extensive lava flows that buried the ancient front side impact basins and adjacent heavily cratered topography which originally was probably just about as rugged as the southern highlands. Some of the southern highlands also may be part of the uplifted rim of the huge farside South Polar Aitken impact basin, with some of the cratering formed from ejecta from that impact.
I was hoping for a little about K2-18b, but I realize you are recording these in advance and then you spend some time editing before releasing. Cant wait to hear more from you about it. When I heard the words dimethyl sulfide I screamed!
Love these videos! It's great to be able to follow these events in cosmology. It's just over 100 years since Einstein explained Mercury's orbit with general relativity. I wasn't around for that but I'm around for this and I'm curious to see how it goes!
My dad and I love watching your videos! My dad is a big brilliant nerd but he is usually very skeptical towards any informational videos we find. Not with you! Hearing him say that you’re much smarter than anything we could ever imagine is proof to me that you’re accurate and knowledgeable. Of course in a way for us common folk to understand. I absolutely love it! I always have the JWST photo page open on my browser and I keep your notifications on! Keep doing what you’re doing! We love it! ❤
This is such a wonderful channel, thank you so much for sharing your knowledge in such an interesting, fun, and understandable and accessible way, Dr. Becky!! :D
The way I see it is that science is simply an ongoing process, and that we'll never really know anything for sure. There's been a crisis in physics, too, regarding the Standard Model, for a long time. It wasn't that long ago that we thought our galaxy was the universe. In a hundred more years we'll have a lot of things figured out. A thousand years later that will all look naive and simplistic. The journey will take us to the very end of human existence, and whatever else takes over after us.
@@psterud then why were the theories we had taught as fact? Open an astronomy book. It's there as if it's FACT. Lying in the textbooks and the sad part is: questioning the science majority gets you ostracized and ignored by major publishers, you know why? Because the marxists dumped millions and laundered in congress to keep lies in the textbook. Namely cosmic evolution was just a bunch of bullSh%t. -An open thinker.
"how much we got wrong" Who is we? The "science community" ostracizes any opposition to current theory. The amount of ignorance your comment holds is hilarious at best.
@@peacepipe6695 If you say so. But it's generally called peer review, and when they discover we got it wrong, things get corrected. It's why there's a crisis at all. What we thought we knew is wrong, so they're trying to find evidence for which dating method is correct. You are right that there have been times when the correct theory has been suppressed, but the facts always win out in the end. So... I'm sorry. But you're just wrong.
As always a splendid video. I watch every chapter because it is all so interesting and you explain everything so clearly and enthusiastically, and yes, I always watch to the end, love those bloopers. Keep up the excellent work
A great video and you explained everything so that a person who hasn't taken physics or is a science major understands. Thank you for taking the time to one make a video and two for explaining and talking about a fascinating subject.
One thing to note: At university I learned that comets couldn't bring the water* to earth precisely because of the Deuterium/Hydrogen1 ratio, as it is too different from seawater. Whereas carbonaceous chondrites would have the right composition. Unless comets have varying compositions with some closer to the right D/H ratio, the D/H ratio of earth has significantly changed over time or if this information is out of date, this might have been an error? However, having more data on the composition of "stuff" on the moon is always good, so good job India! And good job Dr. Becky for bringing us science news! EDIT: Not primarily from comets*
@@br.mright, but if the Bible is true it describes the Universe from a different framing of time than as we currently experience it, so it doesn't necessarily agree with our framing of time and history. That or a reality slice, but effectively the same concept.
@@YMasterS Sure. I was just saying that God is the reason we have water. God is the reason we exist at all. Thanks for your delightful reply. All these other people replied to me too but they seem more confused about reality. They seem to have dismissed the Bible as having been written by stupid people.
@br.m That's probably what they intended to say, but there's a big difference between stupidity and ignorance. People who went before us weren't dumber. They were less knowledgeable. Shepherds 4000 years ago were not dumber than educators today.
I love it when Crisis are found because it means possible advancements to our knowledge or asks new questions and maybe confirm or dismiss current theories or schools of thought.
It seems to continue that the more we learn, the more we realize how much we don't know, and that's exciting! Great bloopers as always Dr. Becky, this batch was exceptional! Blessings from Oregon, USA
The sad thing would be if the JWST went up and only proved what we already knew, I’m happy that it’s causing a crisis in cosmology, it only goes to show that we have sooooooooo much more to learn ☺️
Your bloopers always put a smile on my face to I always watch to the end. Perhaps a future AI can give us a mathematical solution to computing infinities better than re-normalization. Maybe by using algorithms using division and multiplication to identify and manipulate infinite points? This way we will never be limited again.
I would like to thank you for writing "A brief history of black holes". I got a copy last month, completed last week. From the perspective of a simple data engineer with no academic training in astro-anything, I thoroughly enjoyed every bit of it. It was such informative yet fun read. Thank you for making space interesting to non-experts like me. This was not my first "space-related"(yes, I am that novice) book, have read a few SH, Bryan Green. Now as good as those books were, this one was the first one where I finally learned the difference between astrophysics and astronomy (I am absolutely sure that's not the highest of praise you will receive for the book, but it's a very important one for a hobbyist like me). P.S. I can only imagine how hard space is, but I agree whole heartedly that "words are harder"
@@axeman2638 I do actually. I am assuming you are NOT calling the entire book "fantasy fiction" and talking only about the references made in the book. Either way, it still is a good read imo. Cheers.
The fact that Mars had all the ingredients for life is exciting for me because it raises the odds that the ingredients for life are common across the universe. If a crappy little cold planet like mars had all (or nearly all) the necessary ingredients for some length of time, I feel more hopeful that many stars will have more ideal worlds that have actual life.
@@RedPoppyMusicWouldn't that be more like 500 million years? Life on earth seemed to appear almost immediately after the oceans formed so same could be true on Mars and 500 million years seems more than enough time for something to show up.
@@FriedrichHerschel True! Although there are a lot of possible answers to that question that aren't necessarily bad. My preferred solution (and just from wishful thinking) is that once civilizations reach a certain level of advancement, us poor simple primitives just don't realize what we are seeing. If we step back from the idea that we are 'advanced', and recognize that there are both technological and biological limits to what we can even think about, there must be a whole realm of things that lie outside those limits - maybe even vastly more than lies inside those limits. And those limits would not necessarily exist for vastly more advanced species, who could operate in ways and on scales we literally cannot imagine. We could be less than ants to truly advanced aliens, and just as unable to comprehend them as ants are to comprehend us.
I love these Night Sky News episodes and you keeping us non-scientists up to speed on all the exciting research and data coming out of JWST and other projects. I love your book as well (the content), but the cover is so amazing too!
Thank you so much for making this accessible to non-physicists and for keeping us up to date. Even if we seem to be a bit lost because of the crisis, I love that that's precisely what gets you excited because it means potentially learning more. Such a cool mentality.

I always enjoy watching the bloopers at the end! It shows how much effort it takes to create each video, and to deliver your messages, in an apparently seamless form, making them easier to understand, while the process for making them is anything but easy.
I have to say I get more detail from these videos than I have reading many books. And I have read many concerning cosmology. It’s the first time I have heard the “bias bright” term. Thanks.
I enjoy your channel greatly, learning about "The Venus" and "Sa'urn". 😉 You do an excellent job of explaining these topics without bringing in a lot of maths ... I look forward to watching more. I have both of your books (haven't had a chance to read them, but I have them)...
Been watching Venus for a couple weeks already. I thought it was Mercury at first until I realized it was too far out in front of the sun. Plus it's shiningly bright and I've learned how well formaldehyde reflects light ;)
Just a lowly engineer here, but you hit one of my pet peeves. Both the CMB and Distance ladder methodologies are getting more precise, but since the error bars no longer overlap, at most only one of them can be getting more accurate.
Loved the outtakes and had actually pre-ordered the paperback earlier in the week as I'm trying to read more and have almost finished (re)reading A Brief History of Time :)
To me, the reason the 2 models don't line up perfectly is because one is microwave background and the other is telescopes. Is it possible that the lengths of a wave from either in spacetime, is causing a shift in the data. Like depending on what you are looking at between CMB and JWST, they might be showing us two parts of a wider spectrum of the expansion, basically I'm saying different things stretch at different speeds and times and lengths, and that's just the way our universe is.
That's the obvious answer. Unfortunately, the types of people working on this prefer being 100% correct with little wiggle room. Ego and justifying paychecks and all.
Always look forward to the Sky News vids! 🙂 This coming weekend will probably be 1 of the last where the skies will be clear enough to see stars.. P.S. Yes, I always watch to the end... 😎
Hello. I have a question that I cannot find an answer, either with NASA, ESA, RUclips or The Internet Search Engine: What are the ages of the galaxies in The Bootes Void. I have even searched for one called PGC 84225 galaxy to no avail. Thank you.
1. We have the Hubble tension 2. Black matter has not been found 3. We found indications of a fifth fundamental force 4. We found the Muon G-2 anomaly 5. It is well known that our current theories cannot describe the physics inside a black hole and so our theories are incomplete. 6. We actually don't have the slightest clue how gravity works. We can describe its with relativity effects, but how it works (at the quantum scale), why it is so weak etc... we have no clue. 7. Dark energy anyone? Isn't the evidence becoming over and overwhelming that maybe we should stop doubting our measurements until eternity and we should revisit out theories? Yes, relativity and the standard model have served us well. And they continue to be good theories. However, science is treating them like a sacred cow. Any measurement not conforming to them has to be a measurement error and it is getting silly. It's time to slay the sacred cow. Urgent time.
Title: "Crisis in Cosmology" Starts of with: "this video contains a paid partnership with Betterhelp" ohh, boy... I guess it's needed then, this crisis most be really bad ;-)
Over 20 minutes of stuff I didn't come for, just to get to what I did come for...bad practice... If what you want to talk about can't get people here on its own merit, then it probably isn't worth droning on about for 20 minutes.
Why is it a crisis that all your child like WAG's based on woefully incomplete data turned out to be wrong? It would've been a story if you all *weren't* wrong.
Why does nobody talk about the % of redshift caused by mass loss? When light comes out of a gravity well, it is red shifted. If this light then travels into another gravity well, it is blue shifted. Thus if a photon travels between two stationary equal masses, the photon will end up back at it's starting wavelength. But if the destination has less mass, the net result is a red shift. For example, our own sun appears to be receding from us at 633 meters/sec due to gravitational redshift (nobody attributes this redshift to the big bang). Meanwhile, our galactic cluster steadily loses mass - something like - 6.6 billion suns every 400 million years. This reduced mass causes less blue-shifting on distant light, meaning it remains red shifted. The longer light travels to get here, the more of our mass has burned off, and the more redshifted that light will be. This says light will be redshifted in direct proportion to the distance it has traveled to get here. Sound familiar? But how big is this effect? I am no expert, and can't find any resources on the internet.
I have a question that I haven't found an answer to yet. We receive light (or energy) from stars that, according to our models, are millions of lightyears away, right? So that light has been travelling for millions of years, crossing an immense distance in space. And when it finally gets to earth, we measure it's wavelength and feed it into our models, so we can make predications about the distance it had to travel. But how do we know for sure that the wavelength of the light that we are measuring, has only been influenced by the distance that it had to cross? Couldn't it be, that during it's million year journey through space, something else influenced it's wavelength? In other words, is our understanding of what's out there in space, really that good that we can say for sure that the only thing that can influence the wavelength of light, is the distance it has to travel? Modern science is about 500 years old and it's based on measurements that have been done, from just a single fixed point in the universe. So I find it hard to believe that we have a good enough understanding of what's out there, to make predictions about how old or how big the universe really is. But maybe I'm wrong. Btw, love the channel Dr. Becky, your passion for science is inspiring :)
Great episode. Better than any similar show on TV (British - you know what I mean) They should at least give you significant time each month, if not an entire monthly show to yourself.
I've been following your videos for a few years now. You fill a void left by Jack Horkheimer, and add more news about recent astronomical research. Please keep it up! Oh yeah. Chandrayaan was launched by a different country whose name starts with I: India. :)
"Indian Space Research Organisation" is in the video captions starting near 6:48. Dr. Becky also used the term Roscosmos at 6:36, so she's talking about space organizations rather than countries, as noted in previous replies. Edit: added note that this comment is building on previous replies.
Hey you need to talk about OSIRS-REx the spacecraft thats been in space 7 years and by alighting on bennu’s surface which is an asteroid and took a huge sample from it and the spacecraft will be here next Sunday, and bennu is an asteroid that could hit earth in about 130 years.
I just saw a story that Polaris, a cepheid variable, is not behaving like we think these stars should act. Until we have a couple hundred years of observation, for many other cepheid variables maybe we should no longer use them as standard candles. It seems like this would throw off our distance ladder. What do you think @Dr. Becky?
I see that scatter plot and I shudder to think that maybe we were just watching patterns in the noise... 😰 But about that Hubble tension conundrum, maybe the universe expansion is not as uniform as we think? It is often the case that when things don't add up, it is because one of our basic assumptions is wrong.
Look at the supernova, definitely not uniform. I think it is worth considering uneven expansion, especially given even expansion does not seem to exist in other natural phenomenon.
Isn't the LIGO observations the thing that would give us the hubble tension for free? Do we need something more to deduce it from the gravity waves and xrays from the same objects?
Chemist here: you don’t need dry/wet cycles to produce amino acids, proteins, or dna/rna. Wet is just fine…but it is still exiting to find water on mars, and most of your conclusions remain valid. But that’s not due toe wet/dry cycle.
Betterhelp is an awful organization that preys on the rising desire for mental health counseling and I am INCREDIBLY disappointed at your choice to allow them as a sponsor.
There has always been a problem with using Red Shift for distance for very distant bodies. That error flows to most every other theory. It’s not a Fact. It’s a Theory.
Hi @DrBecky In answer to your question, Yes! I always watch until the end! Not only do you make your particular brand of science 'real' by the clear and concise nature in which you explain and describe the subject matter... But you make yourself 'real' by including any mistakes, bloopers, or funny bits you encounter in your journey creating the video for us all to enjoy. And I, for one, could not be more grateful. And by 'real', I mean that despite your long list of credentials, qualifications, publications, and relative fame within the Science World - you haven't let it get to your head like some others have. You are the Real Becky, from down the street, with the occasionally noisy neighbours and that bloke over the road with the Motorbike. And you show us that side of you, which I cannot praise or applaud enough! I love your shows, your book is the only thing on my Christmas list right now, and I Thank You most sincerely for all that you have shared with me, and the others watching... Warmest Regards, Tigger
Dear Betty, please don't promote mental health companies that were recently fined for selling patient confidential information. I appreciate the astronomy and I hope that a 5 minute google search as a background check on your sponsors isn't that much to ask.
Why bother with technological advances if you're just going to blindly and dogmatically cling to your five hundred years old standard model of cosmology
There are lots of moons, hence the "the" denoting the Earth's single moon. Or you could call it Luna which needs no definite article. So as you can tell, I watched to the end.
Thanks for another fascinating, informative video. Yes, I do watch right to the end, I love the bloopers. It’s good to know that even experts are human as well!
Awesome content Dr. Becky please keep the hilarious out takes! Does the new paper from Tully, Howlett, and Pomarède about the Ho’olielana first baryonic acoustic oscillation agreeing with the CMB Hubble expansion rate give us a clearer picture to resolve the Crisis in Cosmology?

I still l have vivid memories of the Southern Milky Way overhead in the late hours , complete with dark dust lanes . I sometimes used to lay on a blanket watching the Milky Way and looking for shooting stars . Its all gone now in just 1.5 generations .
No, I don't watch this channel for the bloopers, BUT they do provide a way of unwinding from the wonderful amount of detail found in each episode. Yes, they are entertaining.
Another wonderful episode, and always to the end.
Everyone is always saying for the red/blue shift it being based on the speed of the galaxy but shouldn't it be a bit more complicated as during travel the space expands and accelerates and whatnot, how to take that into account mathematically?
Doesn't this just show that our current models are fundamentally flawed, which isn't all that surprising, because it's consistent with other discoveries from JWST that prompted to rediscuss a lot of previous assumptions?
I'm curious how we would be able to tell how much water on Earth, if any, came from impactors. In the event that the Indian lander does find water there, wouldn't any indicators be long gone for them having a "common" source? Between the natural functions of our biosphere and any water on the moon being exposed to increased levels of radiation, wouldn't it be impossible to tell by now?
It will also depend on how lunar impactors carried ice and how many of those carried large quantities, wouldn't it? Just finding ice is far from enough to say that any, significant, amount of water is extraplanetary.
Why are all the craters on the moon more or less a perfect circle? Do meteors always strike at 90 degrees?
They’re electrical plasma discharge craters.
Words are hard especially tough words like obdurate. Of course we watch until the end as I hypothesise that that’s often one of the best parts. 😂
Love the science as much as the bloopers. Keep it up Dr. Becky.

Pretty sure that if/when ET lands I'll only find out about it on RUclips.

Interesting to note, even though Chandrayan 2 lander had crashed, the orbiter of that mission is still functional and communicated with the new Chandrayan 3 lander. That's some nice way to save money haha. FYI Chandrayan3 did NOT land on the South Pole, not even what's considered polar region. Nor does ISRO said it landed on South Pole, It's the Indian Press that added Masala on the news for views. They did the same with Mars orbiter mission calling it Mangalyaan.

Like the "Ultraviolet Catastrophe", the "Crisis In Cosmology" almost certainly reveals a fundamental lacuna in our current understanding of Physics and Cosmology.
There's no reason that should be "almost certain". It might be as well some minor tweaks to the models.
I saw your comment directly after posting mine (herewith), thunked my sentiment was to be a lonely one. 👍

I'll not watch this episode on principle (clickbait does not a view make,).

Neither will I contest this definition of crisis; such is squarely within semantic boundaries [κρίσις/krísis (Greek): distinguishing/separating-personally, I implement it as "turning point"].
I will, however, question its deployment: ad hoc hype (viz. viewership,) brandished rather blatantly. I thought better of Dr. Becky (and other science communicators).. unfortunately, my hope for a better future is whittled a little each day by the very idols claiming to keep them. 😔
We are talking about a 9.5% discrepancy. We may learn something new, but it will not be "catastrophic". If you are looking for a blockbuster, explain dark matter.
Welp, what a difference 2 hours makes; I no longer interpret the above comment the same way I did before.. as such, I don't think my comment belongs her but I'll leave it (at least for now) as I still feel the same except I'm reconsidering watching the video, curious to see how she handled it.

You strike me as hyper-intellectualized.
I'll save you a lot of stress (but you probably know this already): the fundamental problem is CAPITALISM.
One cannot (click) bait where there are no (swedish) fish.
A more interesting question is: what do you think of Lee Smolins characterization of quantum mechanics as "incomplete?" He argues that the three axioms that govern QM (e.g. Born Rule...) are fundamentally inconsistent conceptually and as such we need a conceptual re-thinking of QM that reproduces the same math but under internally consistent conceptual conditions.
He, astutely I might add, cites Ptolemys epicycles to aid his thesis. He argues that the math in Ptolemys Epicycles was actually very accurate, but it was conceptually incorrect even though the underlying mathematics was generally right - or close enough to right.
Just curious what your thoughts on that were.

I still think the solution to the crisis in cosmology is that the CMBR is from when the universe was in early access, before all the physics bugs were fixed. QA wanted to reset and have a new big bang, but the business people said nobody was around to notice and it was too late by the time the devs pointed out that there would always be leftover light traveling through the universe.
Looking around the sections of the app we can see, I suspect we are still only in early beta testing, the local variables seem to make sense but the global variables are still confusing.

Science is always about new discoveries disproving old ideas. Looking forward to seeing more from JWST.
It’s still up to people to interpret data. All JWST does is collect it. People interpret it. Looking into space with night vision goggles at objects normally only seen by Hubble. Still doesn’t have a tag or time stamp as to what ones looking at.
I don't get the panic. The age of the universe and expansion rates were based on poor data, personally I expected a change. Question is why the surprise? Your models were wrong haha!
yes, but the problem we have had for the last 70 years is that if your Peer-Reviewd (yet unapproved/published) paper rocks the academic boat too much it will be rejected and then all the scientific papers you have in the scientific journals are just rehashes of existing papers with different spins on the titles you get very little progress. Old men will go to extraordinary lengths to protect their work - even if they were wrong.
So that means science is always wrong.
@@off6848, science isn't wrong, the old guys who hold onto their 30-50 year-old theses are wrong; scientists question those assumptions, they just don't get published in peer-reviewed journals. So all scientists have to do it outlive those old guys... (Okay, it's way more complicated than that...)

6:23. Becky, please understand that the Chadrayaan-3 lander DID *NOT* LAND AT THE LUNAR SOUTH POLE!!! It touched down in a gently rolling area at latitude 69.37 degrees south, which is 625 km NORTH of the south lunar pole and not at the pole itself. Saying that it landed at the pole would be about like saying that the far northern coastal village of Tuktoyaktuk, Canada is at the Earth's north pole, which it clearly isn't. We have deliberately crashed some probes fairly near the south pole, but no one has yet soft landed very close to it. Also, the moon is too small to act as much of a shield for the Earth during the heavy bombardment period. The reason the southern highlands appear so heavily cratered is that they are not covered by the extensive lava flows that buried the ancient front side impact basins and adjacent heavily cratered topography which originally was probably just about as rugged as the southern highlands. Some of the southern highlands also may be part of the uplifted rim of the huge farside South Polar Aitken impact basin, with some of the cratering formed from ejecta from that impact.

I can't help but feel the crisis in cosmology is just us figuring out how much we got wrong.
The way I see it is that science is simply an ongoing process, and that we'll never really know anything for sure. There's been a crisis in physics, too, regarding the Standard Model, for a long time. It wasn't that long ago that we thought our galaxy was the universe. In a hundred more years we'll have a lot of things figured out. A thousand years later that will all look naive and simplistic. The journey will take us to the very end of human existence, and whatever else takes over after us.
It will be fun.

@@peacepipe6695 If you say so. But it's generally called peer review, and when they discover we got it wrong, things get corrected. It's why there's a crisis at all. What we thought we knew is wrong, so they're trying to find evidence for which dating method is correct.
You are right that there have been times when the correct theory has been suppressed, but the facts always win out in the end. So... I'm sorry. But you're just wrong.

One thing to note: At university I learned that comets couldn't bring the water* to earth precisely because of the Deuterium/Hydrogen1 ratio, as it is too different from seawater. Whereas carbonaceous chondrites would have the right composition. Unless comets have varying compositions with some closer to the right D/H ratio, the D/H ratio of earth has significantly changed over time or if this information is out of date, this might have been an error? However, having more data on the composition of "stuff" on the moon is always good, so good job India! And good job Dr. Becky for bringing us science news!
EDIT: Not primarily from comets*

The fact that Mars had all the ingredients for life is exciting for me because it raises the odds that the ingredients for life are common across the universe.

The more likely life gets, the bigger the question "where are all the aliens?" becomes.
@@FriedrichHerschel True! Although there are a lot of possible answers to that question that aren't necessarily bad.
My preferred solution (and just from wishful thinking) is that once civilizations reach a certain level of advancement, us poor simple primitives just don't realize what we are seeing. If we step back from the idea that we are 'advanced', and recognize that there are both technological and biological limits to what we can even think about, there must be a whole realm of things that lie outside those limits - maybe even vastly more than lies inside those limits. And those limits would not necessarily exist for vastly more advanced species, who could operate in ways and on scales we literally cannot imagine. We could be less than ants to truly advanced aliens, and just as unable to comprehend them as ants are to comprehend us.

To me, the reason the 2 models don't line up perfectly is because one is microwave background and the other is telescopes. Is it possible that the lengths of a wave from either in spacetime, is causing a shift in the data. Like depending on what you are looking at between CMB and JWST, they might be showing us two parts of a wider spectrum of the expansion, basically I'm saying different things stretch at different speeds and times and lengths, and that's just the way our universe is.

Hello. I have a question that I cannot find an answer, either with NASA, ESA, RUclips or The Internet Search Engine: What are the ages of the galaxies in The Bootes Void. I have even searched for one called PGC 84225 galaxy to no avail. Thank you.
1. We have the Hubble tension
2. Black matter has not been found
3. We found indications of a fifth fundamental force
4. We found the Muon G-2 anomaly
5. It is well known that our current theories cannot describe the physics inside a black hole and so our theories are incomplete.
6. We actually don't have the slightest clue how gravity works. We can describe its with relativity effects, but how it works (at the quantum scale), why it is so weak etc... we have no clue.
7. Dark energy anyone?
Isn't the evidence becoming over and overwhelming that maybe we should stop doubting our measurements until eternity and we should revisit out theories?
Yes, relativity and the standard model have served us well. And they continue to be good theories. However, science is treating them like a sacred cow. Any measurement not conforming to them has to be a measurement error and it is getting silly. It's time to slay the sacred cow. Urgent time.
I keep hearing "Israel" when you say "IRSO."

Don't remember asking you a damn thing.
Why does nobody talk about the % of redshift caused by mass loss?
When light comes out of a gravity well, it is red shifted. If this light then travels into another gravity well, it is blue shifted. Thus if a photon travels between two stationary equal masses, the photon will end up back at it's starting wavelength. But if the destination has less mass, the net result is a red shift. For example, our own sun appears to be receding from us at 633 meters/sec due to gravitational redshift (nobody attributes this redshift to the big bang). Meanwhile, our galactic cluster steadily loses mass - something like - 6.6 billion suns every 400 million years. This reduced mass causes less blue-shifting on distant light, meaning it remains red shifted. The longer light travels to get here, the more of our mass has burned off, and the more redshifted that light will be. This says light will be redshifted in direct proportion to the distance it has traveled to get here. Sound familiar?
But how big is this effect? I am no expert, and can't find any resources on the internet.
I have a question that I haven't found an answer to yet.
We receive light (or energy) from stars that, according to our models, are millions of lightyears away, right?
So that light has been travelling for millions of years, crossing an immense distance in space.
And when it finally gets to earth, we measure it's wavelength and feed it into our models, so we can make predications about the distance it had to travel.
But how do we know for sure that the wavelength of the light that we are measuring, has only been influenced by the distance that it had to cross?
Couldn't it be, that during it's million year journey through space, something else influenced it's wavelength?
In other words, is our understanding of what's out there in space, really that good that we can say for sure that the only thing that can influence the wavelength of light, is the distance it has to travel?
Modern science is about 500 years old and it's based on measurements that have been done, from just a single fixed point in the universe.
So I find it hard to believe that we have a good enough understanding of what's out there, to make predictions about how old or how big the universe really is.
But maybe I'm wrong.
Btw, love the channel Dr. Becky, your passion for science is inspiring :)
Good to see many astronomers talking about Chandrayaan-3..❤ 🇮🇳
Great episode. Better than any similar show on TV (British - you know what I mean) They should at least give you significant time each month, if not an entire monthly show to yourself.
I've been following your videos for a few years now. You fill a void left by Jack Horkheimer, and add more news about recent astronomical research. Please keep it up!
Oh yeah. Chandrayaan was launched by a different country whose name starts with I: India. :)
Yeah, I wonder how long this video is going to stay up, it's a pretty major "blooper". Although I think you can upload a new audio track.
I thought the same at first but it seems shes saying ISRO, the indian space program
@@axadian Definitely saying ISRO as she repeats it saying ISRO researchers have first access to the data - so not a blooper.
"Indian Space Research Organisation" is in the video captions starting near 6:48. Dr. Becky also used the term Roscosmos at 6:36, so she's talking about space organizations rather than countries, as noted in previous replies.
Edit: added note that this comment is building on previous replies.
I said the acronym ISRO (Indian Space Research Organisation) as a word, in the same way one would with NASA. Not Israel
Hey you need to talk about OSIRS-REx the spacecraft thats been in space 7 years and by alighting on bennu’s surface which is an asteroid and took a huge sample from it and the spacecraft will be here next Sunday, and bennu is an asteroid that could hit earth in about 130 years.
I just saw a story that Polaris, a cepheid variable, is not behaving like we think these stars should act. Until we have a couple hundred years of observation, for many other cepheid variables maybe we should no longer use them as standard candles. It seems like this would throw off our distance ladder. What do you think @Dr. Becky?
I see that scatter plot and I shudder to think that maybe we were just watching patterns in the noise... 😰
But about that Hubble tension conundrum, maybe the universe expansion is not as uniform as we think? It is often the case that when things don't add up, it is because one of our basic assumptions is wrong.
Look at the supernova, definitely not uniform. I think it is worth considering uneven expansion, especially given even expansion does not seem to exist in other natural phenomenon.
Isn't the LIGO observations the thing that would give us the hubble tension for free? Do we need something more to deduce it from the gravity waves and xrays from the same objects?
Ligo has been observing gravity waves for over 10 years now. What makes you think it is going to help with the hubble constant?
Chemist here: you don’t need dry/wet cycles to produce amino acids, proteins, or dna/rna. Wet is just fine…but it is still exiting to find water on mars, and most of your conclusions remain valid. But that’s not due toe wet/dry cycle.
Abiogenesis on Mars, making DNA from mud? Time to study the human genome my dear, for a complete rethink of *that* possibility 😃😁😀
Betterhelp is an awful organization that preys on the rising desire for mental health counseling and I am INCREDIBLY disappointed at your choice to allow them as a sponsor.
There has always been a problem with using Red Shift for distance for very distant bodies.
That error flows to most every other theory. It’s not a Fact. It’s a Theory.
Is there any possibility they've been measuring Redshift wrong this whole time? You can switch change in distance for change in mass in the equation.
Hi @DrBecky
In answer to your question, Yes! I always watch until the end! Not only do you make your particular brand of science 'real' by the clear and concise nature in which you explain and describe the subject matter... But you make yourself 'real' by including any mistakes, bloopers, or funny bits you encounter in your journey creating the video for us all to enjoy. And I, for one, could not be more grateful.
And by 'real', I mean that despite your long list of credentials, qualifications, publications, and relative fame within the Science World - you haven't let it get to your head like some others have. You are the Real Becky, from down the street, with the occasionally noisy neighbours and that bloke over the road with the Motorbike. And you show us that side of you, which I cannot praise or applaud enough!
I love your shows, your book is the only thing on my Christmas list right now, and I Thank You most sincerely for all that you have shared with me, and the others watching...
Warmest Regards,
Tigger
Dear Betty, please don't promote mental health companies that were recently fined for selling patient confidential information.
I appreciate the astronomy and I hope that a 5 minute google search as a background check on your sponsors isn't that much to ask.
Why bother with technological advances if you're just going to blindly and dogmatically cling to your five hundred years old standard model of cosmology
BetterHelp should spend less money marketing and more money recruiting and vetting qualified professionals.
There are lots of moons, hence the "the" denoting the Earth's single moon. Or you could call it Luna which needs no definite article. So as you can tell, I watched to the end.
Can miles truly separate you from friends... If you want to be with someone you love, aren't you already there?
Thanks for another fascinating, informative video. Yes, I do watch right to the end, I love the bloopers. It’s good to know that even experts are human as well!
Awesome content Dr. Becky please keep the hilarious out takes! Does the new paper from Tully, Howlett, and Pomarède about the Ho’olielana first baryonic acoustic oscillation agreeing with the CMB Hubble expansion rate give us a clearer picture to resolve the Crisis in Cosmology?
