👩🏽💻 I'm Dr. Becky Smethurst, an astrophysicist at the University of Oxford. I love making videos about science with an unnatural level of enthusiasm. I like to focus on how we know things, not just what we know. And especially, the things we still don't know. If you've ever wondered about something in space and couldn't find an answer online - you can ask me! My day job is to do research into how supermassive black holes can affect the galaxies that they live in. In particular, I look at what processes can feed growing black holes and whether the energy output from the disk of material orbiting around a growing supermassive black hole can stop a galaxy from forming stars.

Hi, someone who did a PhD on Sgr A* here. There seem to be quite a few things lacking in the work presented here.
1. They make no mention of the regular flaring activity of Sgr A*, which would be difficult to explain with a dark matter blob (you can read Genzel 2010 review for details).
2. They also don't mention any of the 3 mm high resolution observations of Sgr A*, which, are slightly larger scale than the expected Event Horizon Telescope observations, have given extensive description of the close vicinity of Sgr A*, along with the recent observations with the GRAVITY instrument on VLT.
3. The lack of disintegration of G2 can be easily explained by the fact that it is/was likely to be a dusty cloud with a stellar core (i.e. small star with gas and dust surrounding it), instead of a cloud of pure gas. This has been suggested already back in 2012-13 (see Eckart et al 2013, Valencia-S. et al 2014 for further discussion on this).
This premise of this paper is based on only one factor, while ignoring a plethora of other evidences we have for Sgr A* being a supermassive black hole.
According to certain woo peddlers, it's just the galactic battery for interstellar electricity ... have you ever observed that? (Careful doubt on my side)
Thanks Abhijeet for the extra context!
Interesting remarks. Thank you for this comment.
Yes, one needs to explain all the data.

“A lot day and not a lot of night” is an understatement where I live. The sun hasn’t set this month 😆🌞
I am from Finland and have same problem.
Think of it as the ultimate daylight savings time.
I don’t have it as badly here in Seattle WA, but yeah! It’s a hard sell when I’m trying to get my toddler to go to sleep at 8:30, when it looks like 5pm outside and people are mowing their lawns.

Or summer time, as we call it in Europe.
Same. The sun is well up in the sly at 2am. Glaring through my window and right on my pillow at 3am
I like "a perforation of black holes". This one has to win.
I liked a "Doom" even more but this was my 2nd choice and would have been a very fitting one, third was "colloquium"but it's the most boring one (according to me) that won. I won't spoil it, go check the link.
I didn't like it at first, but it's growing on me the more I think about it as a singularity perforation in spacetime.
Turned out the voting was already over before I casted mine and it was depressing, like saying "a grouping of birds is overhead. And, yeah that's why I liked "perforation", too, because when you boil it down, a perforation is just a bunch of holes.

To be fair, black holes are quite disastrous to anything near them - unlike crows. Alas the garbagemen of nature always get the short end of the stick.
@@Tiwack01 I mean.... not really. If you get too close to the sun you will be hosed as well but we don't go around calling stars a disaster. They are just a strong point of gravity. If they are giving off jets and you are near that, yes, could be a disaster, but stars have flares, Pulsars have jets, Magnatars may create these radio bursts, etc. Every large object has it's dangers but black holes are seen as some cosmic vacuum just sucking up anything around them and it doesn't work that way.
@@Tiwack01 Well technically the garbagemen of nature always get EVERY stick.. :D
The only News I'm actually looking forward to 😅
👍 EXACTLY
The only news that *is* news.
For a more in-depth history of the planet around Barnard’s Star, I can’t recommend ParallaxNick’s video highly enough: czcams.com/video/WqHpOKJ8u0s/video.html
You missed the chance to rick roll people
I looked it up to see if I live south of the 40th parallel and got my mind blown when I realized that Philadelphia, PA and Madrid Spain are both at pretty much the same latitude. This has nothing to do with space news, but it's still amazing.
I love your videos! Thanks for making them for us and editing them so well. Oh and thanks for including bloopers. You're adorable😊
Two scientific papers saying essentially, "Is not" and "Is too"
Practically the scientific minds version of "no im right" "no i am"
Yep. But that's just how science works sometimes. We'll find the answer eventually, and until then we have constant debate to help keep the question alive!
@@gibbcharron3469 jup. I think in biology there was a raging debate over ~30 years between essentially 2 labs whether neurons communicate electrically or chemically, and both labs had really good evidence from really nifty experiments....turns out, it´s kinda both, really...
That's a normal and healthy part of the scientific process. Both papers lay out current evidence for their claims, and lay the foundation for future work on the subject which will hopefully get closer to the truth.
That's all science needs to be.
Dr Becky - Thank you for inspiring so many others to pursue science as they will be the future explorers of the universe!
Your channel and content are simply phenomenal. You just managed to make a 30-minute commute a breeze with this video. I'll surely be saving your videos for those sort of situations. Thank you
4:51 I'm sorry, the techincal name ISN'T "toenail moon"? They let us have MUSHBALLS but not TOENAIL MOON?!
One cannot just title a video like that and expect viewers are not going to skip to the supermassive blackhole part of the video before going back to watch the rest! This sounds so interesting!
You’re welcome for the chapters then 😂
@@DrBecky Heh, thank you so much 😅 The rest of the video is awesome too!
I totally did that too.
@@DrBecky thanks for cryptically acknowledging me...

‘Perforation’ is the wholly (/holey) correct answer.
That was really interesting! I'll be disappointed if there's not a black hole at the center of the galaxy, but I guess I'll live.
I wonder if we will live if it forms into a super massive black hole
*rogue black hole, approaching Solar system*: "Guess again."
It’s only conjecture, there’s just no good reason nor much of a likelihood that there would be such of a concentration of dark matter at the center of the galaxy.
So NASA chose the name "DaVinci" for a Venus mission when "Botticelli" would clearly be more fitting for the Venus theme?
Remember that NASA named their moon landing program Apollo, who isn't a deity of the Moon 🎑
Sounds like we may need to rename whatever is at the center of the Milky Way to Sagittarius A Blob.
i welcome our Blob Overlord.
I'm no expert but could it be, that there are different supermassive objects at the centre of different galaxies, that merely heavily resemble each other over such huge distances? Black Holes, Dark Matter WIMPs, other types of dark matter, Boson Stars, Dark Compact Objects all conflated to be the exact same thing, when really it's an overall mix of similar, but different things?
👊 I dare anyone to disprove that there is a gigantic clump of SpongeBob SquarePants’ fart in the center of Milky Way. 👊
This fart itself is what holds the whole galaxy together. #Pseudoscience
There is no Milky Way galaxy.
Please regain your intelligence.
Humans act like fools.
IT'S ALL BAD SCIENCE.
Brilliant as always, Dr. Becky! Thanks again for your videos.
That's not Wall-e.... That's JONNIE 5 & he's ALIVE!!!
Does not compute.
“Remind myself cause I’m not a chemist” - you should partner with someone to flesh that song out to full length :)
First like mam, I'm from India and I have been seeing your videos, and a Msc Physics student.
Thanks for making the show. I love all the references and links. You are truly an inspiration.
You and your content are amazing! Love watching your videos! Cheers from Brazil.
It looks like "swarm" won! We got very close to having to call them a doom of blackholes... Was it the result you were hoping for? Great video btw :) As an astrophysics undergraduate student, your content is very inspiring, thank you!

Another fascinating roundup, thanks Becky!
Another great discussion there Becks. Thank you. AND those bloopers! 😂😂😂
Ingenuity 🚁 dropped a frame of data, so the frames after that didn't sync up with the live environment. (Just shows how amazingly complex space exploration is).
Doesn't help that instructions take from 22 to 40 minutes to get there depending on the position of the planets.
This is my favorite series: "THE NIGHT SKY NEWS".
I love these videos. A nice recap of everything
Wow! I really love the _Night Sky News_ format. Excellent content.
Dr. Becky, when are you going to talk about the "Giant arc"?
is cosmology as we have known it fatally flawed?
is the observable universe appreciably in-homogeneous?
i'd love to hear your thoughts on the subject
A collection of holes is either a "Treasure Hunt" or a "Ditch".
Hahahaha
I'm tickled at the thought of scientific papers discussing treasure hunts in the sky
...or a sure sign that you're stuck at a juvenile detention center in Texas.
I motion for "Whack-a-Mole" to be the official nomenclature.
Dr. Becky's reference a couple of times to having a spanner thrown in the works reminded me of the Arthur Clarke short story called "Neutron Tide" where the debris of a space ship that got too close to a neutron star included a misshapen wrench that was referred to as a "star mangled spanner."
Love these topics keep em coming
Thank you so much for making astronomy so relatable. Have 11 a year old granddaughter I would really like to get to follow you.
The question is not whether it will be a Strawberry supermoon, but whether the strawberry is actually dead.
Thank you Brian and Robin!

Thanks for another fascinating and informative video Dr Becky! 👍😊
You're the best Dr. B! More about the southern sky please!
Another night sky news, I love this series! I always look forward to these.
I like the sound of "A DOOM of black holes."
That is a hardcore name.
Swarm ftw!
@@bennybooboobear3940 Does it swarm though? I think that if the name has to be boring as shit, it has to also be functional, otherwise it just becomes stupid if there's no excuse for being boring.
I like "graveyard", it kinda makes sense considering they are kinda like dead stars.
@@stylis666 well swarm won so lol
Thanks for the clear presentations of (many) things black hole related!, and sky news in general. It helps with laypersons like me to understand our universe. I wish I had come across you're videos earlier, but great to have them during this pandemic staying home and all.
Phew! A lot of info crammed in this month. Thanks!
I actually love brood--swarm used to be my favorite, but brood has easily overtaken it. Personally, I don't see it as a negative word. The only concern is that brood tends to refer to some "relationship" between the insects, and I'm not sure if that's likely to be the case if you were to have a collection of small black holes.
But I do think there's something about them that makes me want to associate them with "bug" imagery (swarm, brood, etc.) The ones I don't like are the weird nouns, like a devastation or a cataclysm--it's not the negative connotation for me, it's the fact that those don't "feel" like they mean multiple objects.
Your news show reminds me of Jack Horkheimer's old show. Well done!
Keep looking up.

Most stuff I've watched/read about dark matter says it doesn't "clump" together like that.
It’s both a black hole and dark matter
@@klassemyra - Or maybe it's both black matter and a dark hole.
@@Mr.Ekshin or perhaps a black dark and a matter hole?
We know at least some of it doesn't clump into large objects but haven't ruled out that it can form large clumps at all
If the amount of it is enormous (ie the mass is huge), then perhaps the gravitational attraction is so great that it can clump together, although dark matter doesn't interact with itself using other forces. But I'm not sure.
We need a tee-shirt: (Front) "If it's not what I want..." // (Back) "...I'll be irrationally sad!"

You may want to toss a coin to your witcher, unless you're fearing no manner of ghouls, hags, and wraiths.
"We" already know what happened to ingenuity. It was a software issue. Basically an image file didn't get written correctly, which made the numbering of these files shift of one. This made the helicopter treat data from the last frame as being from 2 frames past. Obviously for footage velocity analysis, skipping a frame makes you compute bogus speed.
Yes, as per mars.nasa.gov/technology/helicopter/status/305/surviving-an-in-flight-anomaly-what-happened-on-ingenuitys-sixth-flight/ . The only unknown, at the time that post was written (May 27th) was the root cause of the initial glitch.
@@AthAthanasius Which therefore means they still have to figure out what went wrong. You typically need to understand the root cause if you want to prevent it from happening again.
Great to hear a Northern accent! Love this channel, fabulous stuff!
I think that Barnard's star video was the first one of yours I saw. It wasn't new at the time but I did a search for Barnard's star and your video came up. I was hooked and haven't missed any of your videos since then.
No black hole? but we can't see it! it has to be there!

Just so you know: the U in Akatsuki is silent in Japanese, so it's pronounces: Akatski.
"Akatsuki" is a contraction of "akai tsuki" (= red moon).
Also, _astronaut_ is pronounced "astronaut", not "ashtranaut".
@@nagualdesign brittany girls voice. Arrested development.
Doom, horde, swarm, brood sound like something out of the game "Starcraft", so Colloquium falls nearer to hand for that.

I like graveyard haha.
@@graemep.1316 Swarm is a boring one. I'm surprised it won. I voted Doom so I guess I should be happy it at least made 2nd place (I'm an old gamer who loves the Doom series).

Hey, vampires are people too!
Well at least we can invite the astronomers to the party. The vampires have to wait for the winter solstice for their fun.
Hey, Dr. Becky. I live in northeastern Maryland and, as I was walking to the store, I happened to look up at the eastern sky and, though it was very faint, there was the not-quite-half-full Moon hanging on its back at 3 o'clock in the afternoon. And, I just cast my vote for the bunch-of-black-holes name.
this series is amazing, I am really happy right now that I found it :D
Remeber, "doom" isn't a negative word. It merely means a pre-ordained fate.
And we definitely know the fate of a star above a certain mass.
Nothing more refreshing than listening to a smart and beautiful lady.
Beautiful mind and face its a win win..
She is absolutely adorable.
First, keep up the great work in your videos.
Second, I wish I could have helped with the choice of choices for collective nouns for black holes, I would’ve like to see a vote for
“Legion” of black holes. or,
“Gravitas” of black holes.
Ok, I'm going to have to say this… I would honestly LOVE to see Disney animate a character based on you, or YOU as a Disney character! You're totally nailing all the classic moves and gestures and expressions. All we need now is a movie that calls for an astrophysicist with an enthusiasm just like yours that's way off the charts and into space. Please never change! :)
None of us want you to be irrationally sad, give us another hint.
I'm thinking it's colloquium.
@@monoastro I’m thinking cacophony, no idea why just sounds like a physicy word. But we need a clue
swarm is ok
@@Stadtpark90 I put cacophony on top. If it’s wrong and her word doesn’t win then she will be irrationally sad. She’ll post an irrationally sad video. We’ll become irrationally sad from watching it. Then spread that irrational sadness to our friends and family. It will spread like a virus and we’ll have another pandemic
I at first liked colloquium, but perforation is growing on me as the singularities perforate spacetime.
I don't understand why "dark matter " and "black holes" need be mutually exclusive "things"
There's a clear opportunity for you to do a Doctorate in Astrophysics on that theme.
There is roughly four times as much dark matter as normal matter. It's hard to see how 80% of the universe's matter could have formed black holes already. And remember that the effects of dark matter are seen in the CMB.
Also, if there were that many black holes, we would see them, or their effects. They would be passing in front of stars all the time, for instance.
It's thought that galactic black holes may contain only a small fraction of dark matter since it doesn't clump or lose energy from collisions and so doesn't fall into the black hole easily. The most massive black holes may have been seeded by large amounts of dark matter in the early universe though.
@@tonywells6990 You're right. And none of their positions are consistent. At this point they're just making stuff up.
@@davruck1 Literally all your comments on this channel serve only to stroke your own ego by making unjustifiedly assertive contrarian claims with absolutely nothing to back it up.
awesome questions you raise here - the best scientists ask the most interesting questions regardless if they're unpopular or not
Had a hard work day in second shift, thank's dr B for cheering up the day
anyway since i have no one to tell this, do you think a black hole near a nebula can effect the way a star is formed. Can we use this info to find black holes?
I think thats how we detect black holes as how they distort different things and the stuff spiralling around them helps us pin where the event horizon is using the stuff spiralling around it.
@@SovietBear. here is my thought process... Obvio the science is wrong becuz I'm still very young but here goes... If a star is taking birth and the nebula region near the star is being pulled by the black hole, our star has less food to grow so considering its brothers from the same nebula, it will be small right. Considering that this star is outside the regular standard deviation of the size of stars of a particular nebula, I thought it would be pretty cool to find a black hole like this
SIEVE all the way!
TY i was like 'yay its Thursday' because your videos are so good
i’d just like to say that your nail polish and blush match so beautifully
I think "a swarm of black holes" sounds the best and the simplest.
winner: 63% Swarm
@@kruleworld it’s not the winner yet. As of now, there needs to be 23% more votes.
20:30 uhm…such a term already exists…”cluster”
Same as you can get clusters of stars, you also get clusters of black holes…?
Although, if we need a unique specific term for black holes in general, I suggest we take inspiration from Star Wars…which before Disney took over had a well known feature of the galactic map, a clusters of HUNDREDS of black holes known as “the Maw”…
So why not “a maw of black holes”
Also, Granzon (from the Super Robot Wars series) has had an attack named "Black Hole Cluster" since the early 90s.

Keep in mind that Ockham's Razor is just a rule of thumb and the simplest explanation may not be correct sometimes. Example, junk DNA was leftover junk from millions of years of evolution because they didn't see what it did. Turns out that that was wrong and there is function to that junk and if something goes wrong with it you'll sicken and die.
Hi Becky. I love your videos, entertaining and so educational. You are such an incredible role model and inspiration for young girls wanting to pursue science as a career.

Love the bloopers 💖
I’m not keen on this “it’s just a blob of dark matter” explanation. Sagittarius A* is too cool of a name for a blob of dark matter.
It would still be a cool name for the blob.
Lol naming aside is this your only problem with it? I read the article back in May when they published, and it certainly seems logical. The problem some have with SMBHs is how did they get so big so "quickly". This solves that problem. Take a big blob of dark matter and have it directly collapse. The ones that don't reach that threshold, still have a massive amount of gravity, just not enough for direct collapse. Kind of elegant if you ask me.
@@barrymak421 I believe it could be integral to galaxy formation in that the clump either creates a monster black hole from its own mass, or the 'concentrated dark matter' (TM 2014 Green Portal Productions) amasses enough "regular" matter to form a monster black hole. #whynotboth
Sag A* is also a radio source, I believe. Does a blob of dark matter explian that?
Possibly. journals.aps.org/prl/abstract/10.1103/PhysRevLett.107.271302
@@rdizzy1 OH! Is it possible that there are no black holes only extremely dense dark matter blobs which gets more denser as it swallow more matter?!
