Dr. Becky has an enthusiasm for science that is a joy to see. She breaks down complicated science in a way that's easy to understand. Her book is also a joy to read.
Oh yes, that is so true... I really like how she present her topics in her videos. And she has good well selected topics. Many thanks to you when you read this, Dr Becky!
My last "formal" Physics class was in 1979. I've never lost my curiosity and your channel, Doctor Becky, satiates my astrophysics branch like no other. Mahalo.
Okay I know I can't be the only one thinking that Dr. Becky's enthusiasm is SO friggin contagious, I absolutely love everything about her and this channel, thank you for bringing us non-academics the hard hitting scientific breakthroughs you all have worked so hard to uncover! ❤
The paper published a week ago that analyzed the Type Ia supernova database, and concluded the Timescape model fits the data better than the Dark Energy model does, deserves a mention.
I think it's a little early for that kind of inclusion mostly because it's SO new and based only on the single set of Type 1A supernovae data and not a more rigorous comparison of other data that would keep it from being part of 2024's "best of" - however, if it holds up under further scrutiny? oh yeah, 100% it'll be one of 2025's greatest discoveries (and probably one of the greatest of the 2020s period) without a doubt!
Such as finding a planet with a atmosphere that we can't explain in any way other than life. FOMO for that. But also already resigned to not be around for that.

I love your excitement on this video. What an exciting year for astrophysics! Thanks for sharing Pip's and her playfulness with the tripod - too cute. 🐈
I absolutely love this channel even though there is so much that is far beyond my limited understanding . Thanks so much to Dr Becky for breaking it all down as much as possible so people like myself can also get a little taste of what is happening out there. Looking forward to the news and discoveries in the coming year, thanks again always so appreciated.
Mery Christmas, Dr. Becky! And to my taste, the Astrophysics story of the year is... Big Galaxies at High Redshift!! Big, brigth, structured Galaxies at z>10, that contradicts the LCDM cosmology.
On a related note, impossibly large supermassive black holes in the early universe. Such as the one reported recently (December 18) in Nature from JWST, that's already at 400 million solar masses just 800 million years after the Big Bang, and comprising a whopping 40% of the total mass of its host galaxy!
The cat in the tripod: Oh yes, cats want to be not just IN the center of attention, but cats want to be THE center of attention ;-) (but only at times when the cats want it so...)
You've become my astronomy news curator. Each new video keeps me up to date on the latest cool astrophysics news. You explain clearly, and with obvious fascination and joy at what we're learning with the almost miraculous instruments now in use. And I never do this, but I'm going to comment on your appearance. You are so seasonal! The earrings and the sweater are a treat for us at this time of year. Happy New Year!
*5-4-3-2-1 Thunderbirds are Go!* "Yes, M'lady!" Dr Becky is my number one, but the Parker probe driving Fab One is a pretty close second. 🤓 Thank you Brains.
With the new telescope this has been an amazing year for Astronomy and frankly I'd be willing to bet my life that we've also gotten some really interesting data no one has really had time to either process and publish! Hope you have a great 2025 Dr Becky!
For the predicted supernova that was supposed to "go off" this past year, when the word "imminent" is used, we keep forgetting that it could be within one year or one hundred years.
Do I have reverse Mandela? Because I clearly remember that after the fiasco of Uranus's "dullness" to the pubblic they did enhance the features in Neptune
We just need those two research teams to have a massive pillow fight and whoever is the last one standing, their team's findings get crowned Best Science Facts.
When I was a kid in ophanage/children's home the winner stuffed phone books in their pillow slip. This became a passage of succession as you got older and caught on to the game mechanic (and had recovered from your concussion).
Some of the other science youtubers have been talking about a new paper that argues that the timescape model is a better fit to observational data than Lamda CDM at almost every distance cutoff, implying that there is likely no dark energy or acceleration of the expansion rate, and my rough understanding is that could also help to explain the Hubble tension, if it's correct.
My guess at your No 1 was that JWST had pushed back the age of galaxies! I was nowhere near. I've long admired your content and presentation; genuinely great explanations of what is going on "out there" and why some astronomical observations matter... so I've watched you for many years and in this video I am suddenly aware of how stunning your eyes are! Shallow of me? Or have you altered the lighting? Doesn't really matter - keep doing what you are doing.
I remember the announcement during the Neptune flyby live coverage (I stayed up All Night for that And recorded it) that the colours were modified so we could better see certain features.
I had two predictions, and was wrong about both of them. First, I thought for sure JADES-GS-z14-0 would show up in the bloopers. Second, I thought for sure that Pip would take the number 1 spot. Happy New Year!
OI model refined the estimate for the Hubble constant (H0) to 69.8 km/s/Mpc The analysis of the Hubble tension using the Early Dark Energy (EDE) model and the Optimal Individual (OI) model reveals a sophisticated interplay between various cosmological measurements and theoretical adjustments. By integrating data from Cepheid Variable Stars, Type Ia Supernovae, Cosmic Microwave Background (CMB) radiation, and Baryon Acoustic Oscillations (BAO), we employed the OI model to optimize the parameters and reconcile discrepancies. The inclusion of the EDE factor provided a significant enhancement, suggesting that early dark energy plays a crucial role in the universe's expansion rate. Through iterative modeling and parameter optimization, we refined the estimate for the Hubble constant (H0) to 69.8 km/s/Mpc, offering a more cohesive understanding that bridges the gap between local and CMB measurements. This approach underscores the importance of comprehensive data integration and advanced modeling techniques in addressing complex cosmological puzzles.
I can't fault that list apart from 5) - my list would replace that with Webb's observation of Vega's smooth planetary disk, which is completely unlike any other disk and suggests we are missing an important piece of the puzzle of planet formation.
Please, please just call it the Hubble tension. I have so many non-science friends who believe it’s a true, massive crisis in astrophysics after reading science news stories. 😎
16:28 Mentioning that the cat is not sabotaging the tripod =P, it's taking ownership of 2 things, the tripod itself, and the area around it, because EVERY vertical object, in a place, can be used by a cat to determine the characteristic of the zone around it, depending on which pheromone the cat "decides" to use for it. The ownership of things for a cat, relies on both, the necessity of the resource in a specific moment (aka: "Everything I see and I want, it's mine because I see it and I want it") plus, the type of pheromone used to "claim" the object or area. With that in mind: The cat DOES NOT live in your house... YOU live in the cat's house. (Yes, useless data for a cosmology youtube channel but my profession commands me) xD [She did asked "why" , though] xD
Hi, I have a question about black holes, that might be worth answering in a video. If time slows in the gravity of a black hole, presumably to almost zero, how does the black hole grow? Wouldn't the material falling into singularity never reach it, or at least not to the rate that we see? Does the mass falling into the blackhole add to the gravity without it actually reaching the singularity?
That might have been thrown in its head. David Kipping spoke about the new study regarding expansion, on Cool Worlds. Would like to get your commentary on that paper, Dr Becky!
Thanks Dr Becky for all the videos you posted in 2024. I look forward to more space news in 2025. I also think you’re gonna need to add the word “Cat” to the title “bloopers” segment in 2025 as your cat seems to now be the cause of most of them 😊
I know it is very recent but the #1 has to be research into the Timescape theory nulifying the need for dark energy and changing the predicted future for the universe.
Well I was completely wrong - I was going for Parker solar probe as number-1, and it didn’t even make the list 🤣. I’m over the ‘crisis in cosmology’ because my feeling is that without a serious revision of models being applied it’s just never going to be resolved…
I have a question @3:45 so why do they have calculations for non-spinning black holes when they all spin, I guess it’s the simplest n easier to calculate but wouldn’t the ISCO radius be different if it was spinning?
As a pleb, I’m wondering if gravity waves interacting with each other and the photons, on their way to us, would account for the different readings from the sample stars?
Hello Dr. Becky and Happy New Year, I hope you had a great Christmas. Now, I have a question about the ol’ Hubble Tension. As I, as a rank amateur, understand it, the CMB measurement of the Hubble constant is at odds with the “standard candle” measurement. I keep thinking about Alan Guth and Inflation. We don’t know what caused that and we don’t know what stopped it, right? Is Inflation linked to Dark Energy and is there a mechanism that keeps turning Dark Energy on and off, thereby we would see that the expansion rate of the universe would vary over cosmic timescales? I agree that it’s a fascinating subject and I wish my command of maths was better so I could understand it all more! I LOVED your book btw!
Dr. Becky... I confess... I had to pause playback after you announced your number 2 pick... You were soo000ooo EXCITED about number two... I thought you would become incandescent when revealing Number One.... and then "the Crisis in Cosmology"... meh... the "Hubble Tension" is created by the current Cosmology, not the current observations. Cosmologies come and go... Observations are forever. Stick with #2.... it's far more interesting, exciting... and REAL.
Really hoping you’ll make a video around the Lambda CDM / Timescape theory which seems amazingly plausible based on its data analysis and might completely change our measurement / understanding of Dark Energy!! (and whether or not it even exists!!)
question for the Dr. - a black hole is the closest nature can come to perfection of a sphere - if spinning - will that sphere exhibit precession - since it is so close to perfection
my question would be, at the inner most stable orbit around a black hole, how "stable" can it be? wouldn't tidal forces or some collision or something eventually slow it's orbit and make it fall in to the black hole?
Great video as always! However, the new beige-checkered background for papers and graphs is a bit distracting, I liked the old white background much better. The checkered pattern in the background is kinda distracting when looking at the graphs and text, please change it back.
Speaking of growing black holes... a question that I always do and never get picked by anyone that knows (snif).... what is the "death" of a black hole?... I mean, it absorbs anything around it that surpasses the event horizons and then.... what... it can continuously "eating" until the infinite time or something happens that it does something else? O.O
Happy New Year! So has Dr. Becky done any articles/videos on the work being done with the Timescape hypothesis? Seems to be an interesting alternative to lamda-CDM. I'd be interested to hear how they are progressing on that.
Dr Becky I anticipate everyday for new videos I absolutely love your content ❤❤ now as soon as I go outside instead of looking down I look straight up 😅
I think the new theory of time dilation replacing dark matter is my no 1 here's a quick question can the cosmic microwave background indicate patches of dilation? Ps if that's a stupid question please be gentle lol
What kind of day was used in that sun's mass per day? Was it a day of our time as we observe it or was it a day in the frame of the galaxy where the black hole is? Those are different because we see far away objects in kind of a slow motion. Two photons emitted by a galaxy one minute apart arrive to our telescopes further then one minute apart because the latter photon spent more time in transit because it had more distance to travel due to the expansion of the universe.
the universe is different ages in different places - example = a black hole and the space around it - that black hole stopped aging the second it was born and the space surrounding it aged slower than the rest of space and anything in it - it is your concept of space/time that needs adjusted to fit the reality of the situation

“I work with supermassive black holes all the time, and..” is one bad ass aside to drop into a conversation ❤😊
I remember watching the Neptune flyby on TV "live". Live as the data arrived on Earth, that is. It was quite exciting.
I feel that the progress in astrophysics is accelerating year by year although a bit slowly
... and there are different ways of measuring it that arrive at different results 🙂
Not unlike our Universe, I feel...
So you mean to say that there's some kind of "dark energy" amongst astrophysics discoveries?
I'll see myself out.
What a pointless comment
