👩🏽💻 I'm Dr. Becky Smethurst, an astrophysicist at the University of Oxford (Christ Church). 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 whether the energy output from the disk of material orbiting around a growing supermassive black hole can stop a galaxy from forming stars.

Wow, the idea of a supermassive black hole just barreling through the blackness of space completely on its own is kind of spooky and amazing all at once.
We already knew that there were "rogue" black holes flying through space as they have been found and observed. The big question has always been "Where did they come from and why?". Now we may have found the answer, BUT figuring out the actual mechanics of the event is going to be a massive challenge and will likely spawn an entirely new specialty in astrophysics. This is truly "groundbreaking" because until this, we didn't even know that it was physically possible. Sure, the data allowed for the POSSIBILITY, but the forces involved are so intense that it was thought to be "just a fun what if?". Now that we have proof that it CAN happen, figuring out the HOW is bound to be very exciting and important work
@@TonyM1961 Ah okay, were the “rogue” black holes that had already been discovered supermassive or were they stellar-mass black holes?
@@ThatBernie I'm honestly not sure. I'm think we could Google it to find out. Should be pretty easy
The irony is that relativity says you can’t move with respect to space.
@@DrDeuteron But space is expanding at relativistic speed and carrying everything in it along for the ride. Since space is expanding faster than our mere worlds of matter, for all practical purposes, we are moving through space
Three blackholes ejected from its galaxy and traveling thourgh the space in opposite directions with one of them leaving a trail of exited gas and brand new strars would be an amazing thing. I would never thought that anything like this is possible. The univers amazes me all the time. Thanks, Becky!
Black holes playing “crack the whip”
I wonder if that's what will happen "eventually" with the merger of Milky Way & Andromeda Galaxies will that happen? We may not be around as Humans to see it.
Definitely not here as humans in 5 billion years timeline for Andromeda to reach Milky Way
Is it possible the ejected blackholes dragged stars with them?
@@daexion Absolutely. She said all that excitement formed new stars. They would already have the inertia from the black hole passing by and would then jettison out into space. Imagine being a civilization in the deep black. Very few stars in the sky but the huge galaxy you left behind.
That title hooked me. Space is frickin wild!! Blackholes getting ejected from galaxies and whatnot. And OMFG that GRB to Sun power ratio blew my mind beyond comprehension!!!!
Not only could I listen to her all day, but she explains things in a way that a layman can understand and comprehend. I could also stare at those beautiful eyes and gorgeous hair all day.❤
As someone who is completely ignorant as to what is out there I find every video you make fun and interesting and that is just the small bits I think I understand. The net makes me feel like I know a real astrophysicist, something I could never have forseen and never ceases to amuse me. Thanks for sharing and interpreting.
I’m thrilled I could help! 👍
I can listen to Becky for hours, so facinating hearing the news, always too short. Safe travels Becky.
Not only that but just fun to watch, too. She is so animated that you could, as I have done with some Sponge Bob cartoons, just turn off the sound and be just as entertained!
She's an odd duck. How does one make repeated Taylor Swift jokes... then talk for several minutes about gamma radiation without a single Hulk joke? And don't even get me started on JWST catching new images of Uranus...
The comfortable, cosy setting of your home is perfect for your Night Sky News.. but.. I dunno.. that bright, sunny setting was so lovely!! The echo-ish sound too made it feel more like we're sitting with you in that apartment.
No need to change what works, of course.. plus sunny days in England don't exist, right?? But it wouldn't be a bad thing if you ever decided to do the occasional video in similar settings to this one! 😊
The images of Uranus are wonderful!! Our immediate neighbors are certainly beautiful!! I always think - we don't even know what we don't know. It's so exciting to see something new - the apparently ejected object is fascinating!!
I'm less frightened of removing the supermassive black hole from our galaxy than I am of someone who can.
Darth Vader would probably figure out how to do it.
Damn!!!! Good point
It's almost surely a purely natural phenomenon - the forces required here are titanic, far beyond that of even a theoretical hyper-advanced civilization.
@@jacksonayres6326your theory is limited
Holy shit i didn't realise gamma ray bursts could emit THAT MUCH ENERGY! Woah. That's unimaginably energetic
Crazy right?! 🤯🤯🤯
@@DrBecky Black Hole: "Now for my next trick ..."
@@DrBecky Hi Becky! I was wondering if the planet could be destroy if one from our own galaxy would aim at us. Thanks
I heard if a quasar went off in a distant galaxy and it just happened to be lined up with earth, all life could be wiped out and we wouldn't even realise it. Extremely unlikely to happen, far more likely we'll get hit by a big rock before then, but it's hard to fathom how big the universe is at some point the numbers are too big to comprehend.
It's pretty amazing though.
Truly the BOAT.
I went outside at 3am this morning because Andromeda was directly in my line of sight. Couldn't see a thing, even with all the street lights off. Join me in my fight against light polution.
Hear hear!!!
I appreciate your stance. Light pollution is a problem, but this time of year is not the time to be looking for Andromeda. Unless you live in a isolated rural town in northern Scandinavia, it just won't rise high enough.
Sorry, that time is past. If you want dark you will have to travel. No way are people going to go without lights and 8 billion people fill the land.
@@RS-ls7mm You don't have to 'do without lights', just deploy them better.
I've been losing that battle one neighbor at a time for years.
Hey you're in Toronto!!! You are an honorary Canadian now! That's how it works, it's that simple!!! 🙌
You're really good at this. Sometimes, I'm not in much of an intellectual mood, and although I'm a long-time subscriber, I won't feel like taking in too much technical info at the that moment. But I'll put it in my watch queue and inevitably, I'll get caught up in what you're explaining. It's not just what you're explaining, it's the way you come across- light-hearted but a technical expert and professional in your field. I've enjoyed your channel for a long time and I'm grateful you make time even during your travels to keep up with your regular features like Night Sky News.
This means the world to me, thank you for sharing 🤗
Thank you for continuing the legendary work of Jack Horkheimer, the star of the PBS series Star Gazer.
Hearing you use the same phrases and similar presentation styles instantly brought me back to my youth when I would record PBS on my vcr just hoping to catch a Star Gazer episode.
Keep Looking Up 💫
The BOAT GRB is a fascinating discovery. It's amazing how much we can learn about the universe from studying gamma-ray bursts.
It should be called the GOAT GRB.
They need so much more datur, though.
ive sused it gamma ray burts are space ships (light/warp/paradox prevention) kinda of sonic boom but with faster then light travel.
so like if you made a loud sound and then travelled faster then sound in the direction of the sound wave
the sonic boom would eliminate the wave as it travelled so you wouldnt be able to hear it.
the same type of thing happens with light but instead of a sonic boom you get a gamma ray burst.
so you cant see where your going to be , or your self after you leave.
big guess but makes sense to me
Nice to see you on this side of the Atlantic (and just across lake Ontario from me!) Great video, as always!!
Dr Becky, you're like the new version of Sky at Night (I loved that show when I was a kid), because you've got another level of passion on top of Patrick Moore's restraint. I love watching science communications even though I don't have the mind to be able to fully focus on it, so I admire people who are so passionate about the things that affect us all. I'll get back to designing interfaces that enable the rest of us to use the discoveries of science.
Good news, the echo isn't terribly distracting 🙂 On the BOAT GRB, it's interesting to see they realized that the sensor peaked out and reconstruct the full intensity.
Becky, you can reduce echo with blankets or towels hung or laid out just outside the frame. You can probably also rent acoustic panels.
They might have been more concerned that the sensor broke.
@@zen1647 For a one time hotel room recording is it really worth it? Content matters more to me than audio perfection.
What echo?
I agree with this. I definitely heard it at first, but this was mainly because Becky almost always presents from her home and I'm used to that acoustic with her vids. After a few minutes of being focused on what she was explaining, I didn't hear the different acoustic effect any longer. The human brain will adjust visual, audio and olfactory inputs to a new norm when necessary. No need to bend over backwards in a hotel room with blankets and such. Sometimes, you just gotta roll with what you got.
Becky i look on CZcams all the time for content like this i have for years and finally i find you in 2023 my brain has ignited its theoretical part again, thank you so much,.
❤
Excellent coverage as always!
Just one glitch I spotted - in describing the way a lunar eclipse looks, it isn't the Earth's atmosphere that makes the edge of the Earth's shadow at the Moon "fuzzy;" it's that the Sun is an extended (i.e., not a point) source of light, being about half a degree in apparent diameter.
Speaking of eclipses, we're 12 lunations (just under a year) away from the second "Great American (Solar) Eclipse," on Apr 8, 2024. Although I'm not much of an eclipse chaser, I'm already starting to get excited!
And BTW, welcome to N. America (Toronto & Huntsville, home of Marshall Space Flight Center)!
Fred
Yep. The red coloration comes from Earth's atmosphere, but the partial shadow area is just where the Sun's disk isn't fully covered.
@@BenAlternate-zf9nr As seen from the Moon. Exactly.
RE: Uranus. You said one side experiences summer for half of its orbit and the other side experiences winter for the other half. Actually each side experiences summer for one half of the orbit and winter for the other (just like earths poles do).
Wow these ejected black holes are so cool!! The turbulence of them plowing through the intragallactic medium is causing star formation even! Reminds me of Merrifield talking about galactic spiral arms ramming gas together to cause star formation. Loved having Becky talk about this but would also love to hear what Mike has to say!
Makes you wonder how many stellar mass black holes are hurtling through intergalactic space and how frequently they enter the milky way.
Makes you wonder, I prefer to focus on more terrestial matters.😝
I've always been fascinated by space and Dr. Becky has allowed me to notice more amazing things in the night sky with these videos. Love the Swift cutaways btw!
Don't worry about UV coming through your hotel window. Ordinary float glass (a.k.a. green glass) is very good at blocking UV. At 300nm, you can expect 1/8th inch glass to block around 99.9% of light. It will still block 99% down to 260nm. (And if you're wondering, I did just measure it on my photospectrometer.)
Great to know, I am a victim of skin cancer so information like this is well handy. I did have to look up spectrometer, but I am guessing I would not be the only one.
@@martynspooner5822 nope. You're the only one.
UV-C dangerous wavelength is 260nm
only problem is if that isn't glass but a glass lookalike like perspex (PMMA)
@@graymalkinHaim I don't know the regulations where she is at, so take this with a grain of salt, but I suspect it is laminated glass, meaning a minimum of 1/4 inch total glass plus the polymer sandwiched between the glass plates. However, it is possible PMMA satisfies local regulations, so it is possible that the window isn't glass as I assumed. Even if the window is PMMA or some other polymer, I would expect it to have UV inhibitors in the polymer, if not to protect the polymer itself (I know PMMA is better than vinyl, but I don't remember if it is completely immune to UV damage), then to protect what is behind the window.
Regardless, it is a fair point you made regarding my assumption that the window was glass.
With the runaway black hole, it’s kind of like Beyblade on the most epic scale imaginable! 😮
😅😅😅😅
I like the way you think.
thx dr. becky for allowing us to keep up with the recent news!
the crazy part is, that black hole was still only traveling 1.19% the speed of light, which don't get me wrong, very fast. but for such a dramatic event it really puts in perspective the difference orders of magnitude present
In a galaxy far, far away
Something strange happened one day
A black hole that once sat at its core
Was suddenly kicked out, leaving everyone in awe
The galaxy was in a state of confusion
As they watched the black hole's ejection
It was a rare and wondrous sight
A cosmic event that filled them with delight
The black hole spun and twirled away
Into the vastness of space it did stray
Leaving behind a galaxy in wonder
A new beginning, a cosmic thunder
The stars shone brighter than ever before
And the planets danced in a cosmic uproar
The black hole's absence brought a new light
To a galaxy that was once cloaked in night
So let us gaze upon the stars tonight
And marvel at the beauty of this sight
For even in the depths of space
There's always something new to embrace.
Chat gpt 😂
Wonderful!
To give you an idea of how bright the GRB is ... we're still detecting it. Like today, six months later. Usually, Swift can only detect GRB afterglows for hours to days. Maybe weeks.
It's so enjoyable watching someone so passionate.
that’s just what I need right now. I was thinking earlier this evening that you might post a night sky news video tonight. And I just looked at my phone and I got a notification. Im so excited. I studied the entire day for my final exam. My head needs some free time haha. (a random German says thank you;))
Good luck with your final exam! You’ve got this 💪
@@DrBecky thanks!!!☺️❤️
Becky, you manage to bring the perfect mix every time IMHO: Clearly sensible utter enthusiasm for the matter, serious knowledge, tons of work put into it, a gift for transporting it to the public in a very enchanting way, humor - you name it. Thank you for all of this and much more. Be safe, keep going, live long and prosper.
Love seeing you in natural light Dr. Becky you look amazing!
👍👍
So good to see Dr Becky, Dr Katie, Dr Matt, all of my favourite science media personalities, together in the same photo. Probably others there who’s names I would recognise, but not faces
I see Derek from Veritasium is there, alongside his wife, Raquel Nuno. I also recognize Randall Munroe. It's a real who's who of astrophysics.
Thanks Dr. Becky, glad you were able to make this episode.
Thank you for another informative and interesting look into the universe. I'm currently studying 1st year Astronomy and I appreciate how you're tying in what you're presenting with what I'm learning ie electrons moving between states and ejecting photons. It's great to see real life examples of classroom presentations.
Wow, cool af, I love Uranus and supermassive black holes. My science school teacher gave me detention for admitting this. I wish I could show her this video to explain these are things to love.
Btw, your passion for science is amazing.
The idea that a gamma ray burst lasting milliseconds can put out more energy than the sun over 6+ billion yrs is just crazy and mind blowing... It's just WOW, huh, OMG, WOW....
When a random event like this occurs, how do instruments, such as Hubble and JWST, get assigned to have a look at it? Since their time is scheduled in advance, who decides to change the schedule? How is it even requested?
How is it commanded? You can’t just say point it there….or can you? Are the command put through a simulator first? How’s the commutation done? We need to know
Excellent video Dr. Becky! This week's space news is very interesting. I loved the references to 1997's Titanic when you were talking about Uranus' year and your reference to Taylor Swift's Anti Hero when you were discussing the B.O.A.T. GRB!
Thank you for coming to TO and on a nice Week. I hope every moment goes great and you have a safe trip back home. I love your knowlege and also the relaxing style that you tell us of the astro news.
I am slowly getting your book read. I am on ch.4 why black holes are black.
Slow down, my heads still not got over Jupiter's red spot not being dust.
The NH3 & C2H2 experiment was fascinating
Nice presentation - loved every minute of it! Such an exciting age of discovery, thank you for being our guide!
The difference between the umbra and penumbra in Earth's shadow is best thought of if you imagine yourself standing on the Moon looking back at Earth. If you see a total eclipse of the Sun you are in the umbra. You are also seeing all of the sunrises and sunsets on the Earth in the red ring around the Earth caused by the Earth's atmosphere (which also causes the Blood Moon). On the other hand, if the Earth blocks only a portion of the Sun you are seeing a partial total solar eclipse and you are in the penumbra of Earth's shadow.
Satuuuurnnn I've missseed you!!!!
Milky way season very soon! Just last week I got the chance to finally image the saggitarius milky way area, with lagoon, triffid, swan and eagle nebulae and I was blown away with just a short 8 minutes of integration! I started in summer of last year but now that I have 1 year in the hobby I am so much more prepared to take on the summer!
wow, best episode ever - lots of science! You, Dr Becky, are sounding like a real physicist -with the enthusiasm for the wonder of the cosmos only increasing as decades of achievements and setbacks, leaps big and small, and plenty of dead ends, too, focus the spirt.
That is said with no intention of offending or patronizing, rather meant to send love and respect your way. I've seen it first hand in several scientist, all of whom are gentle, courageous, lovers of learning who have unparalleled humility and place the education of others and the transferring of the flame to the next generations on equal footing with their personal interests and projects. People like Carl Sagan, Stanley Miller, Bill Borucki, Chris McKay and so many many others. Even people like Sagan of whom there is much documentation and we think we know who they are or were, I can attest that they did twice as much work than any one person knows; constant rational analysis for decades while spreading wonder and encouragement to others, truly in awe of the universe and of humanity as well. True, some people can be difficult to appreciate (looking at you, administrative chemists) and don't deserve our affection or professional respect, but their significance as another amazing human existence must be honored.
Yeah, so wild that out of everything I learned of physics and biology, spectroscope and planetary simulations, that message of humility is the greatest gift of all.
fast moving rogue super massive black holes could be slightly problematic. granted at only 0.5% of c you'd see it coming from quite a distance. A galaxy weight black hole could make a mess of things.
If it's moving that quickly, I don't think it'd stick around long enough to cause any large-scale gravitational distortion. Probably just capture or eject a few stars along its path and maybe throw out some intense radiation from the accretion.
@@BenAlternate-zf9nr 0.005c would be 900 years from alpha centauri to here which is a considerable amount of time for a multibillion sun mass black hole to mess things up. I don't think you quite appreciate the scope of how antisocial such a thing is :)
Maybe the supermassive Black hole wasn’t ejected, maybe it left the galaxy because it needed space 😊
My favorite astronomy news source. ❤️🔥
12:30 "Gamma rays, the most energetic form of light with the highest wavelength are given off."
ITYM "highest frequency"
How does a super massive black hole get ejected, when it is literally the centre of its galaxy and everything orbit's around it !!!!!
By ANOTHER supermassive black hole 🤯
@@DrBecky Ah right, now I get it lol .
I'm not sure why, but my first thought was that some hyper-advanced civilization was lobbing this black hole at an enemy galaxy! Anyway, great video Dr. Becky, love your work!
Of course this is the answer. No reasonable person could argue against a relativistic kinetic black hole kill missile. They'll never see it coming. 😉
Oh my god! What did the other civilization do to make them THAT angry?
"use the force Luke"
Luke messes up and ejects the black hole away from the galaxy
"Luke maybe you shouldn't use the force anymore"
Good choice for the sponsorship. Actually looks useful, unlike the rest of the scams and junk youtube pushes.
"sometimes I use words and I think I know what they mean... but I don't know" so relatable LOL
I'm from West Java and today a partial solar eclipse was happened and I'm mad because it's been cloudy all day 😩
Boooo clouds!
😢
Dr. Becky has the ability to explain complex matters in a way that even I, who have no training in astrophysics, can understand. That is quite an achievement.
You have SO MUCH personality!
We love you Becky.😊
Dr. Becky! Elucidate? To throw light upon. Right up your alley. And you do it so well! Thanks!
Years ago I would watch Jack Horkheimer, with his saying "Keep Looking Up!" Thank you Dr Becky
I love your videos Dr. Becky. Mostly I love how you explain your videos and where we can find the studies, thanks so much
It is amazing how much more we can see now. Thank you for this.
I wasn’t expecting the singing at the end. You have a good ear and set of pipes.
The GRB was pointed straight at us and this is the reason it was so bright here. Just be glad that it came from so far away that we are toast now.
I'll never get tired of your channel Dr Becky. I've been a big fan of yours since your appearances on sixty symbols channel long time ago. Thank you for keeping us informed so well! You rock!
Thank you Dr Becky for another great episode. I have listened to A Brief History of Blackholes and highly recommended it.
It’s wonderful to you see out in the lovely sunshine; I hope you’re enjoying Toronto!
According to most space science channels ive watched, this image is more likely to be a super flat galaxy than an ejected black hole
It would be great if you could have another video where you read through the paper about that runaway SMBH, showing us how do you read papers, what are you focusing on, how do you collect the learnings, etc.
28:55 - elucidate - to make lucid. Lucid: clear. Ergo, elucidate: to make clear. Seems legitimate for the sentence you were in. :)
Yay, words! I found my Compact Edition of the OED yesterday. I mean, that’s a harder go-to than the phone, but it’s sooooo nice. :)
Thanks Dr Smethurst. Amazing stuff. Really enjoying your book also. 👍
At the end when you say that according to our current understanding, you can remove the black hole in the milky way.
I did thought for a moment that you'd say "but please don't test that until we've observed more cases" 😂
This is why we are all special. love the channel. pure inspiration.
Wonderful! Your breathlessness is also wonderful. Do stop and take a breath. :) Best wishes!
You're going to Huntsville? It would be the coolest collab to see you and SmarterEveryDay connect on anything/everything about space!
Hi Becky you got to be the most exciting girl that I had ever found in CZcams. Your are the coolest one and I like all your videos. They are all so interesting and informative. Keep on posting new videos.
Thanks for these- definitely subscribing for more. And, I hope you enjoyed your trip to Huntsville!
Love your channel❤. Thank you for sharing.
Super exciting episode here. Great work. Lots of extraordinary developments. ❤
Thank you so much for showing the outtakes at the end. It’s refreshing to have that transparency. You got a quick sub out of me plus I look forward to new content and checking out the back log.
You are my new favorite channel. Great video!
Really appreciating the long-form Dr B! Excellent as always 👍
Well done Dr Becky.
I really appreciate these videos. I rarely have time to look through all of the information available.
JWST is such a marvel of engineering. What I find more awesome are the people who designed, built, and use it! They're the brightest stars in our galaxy as far as I'm concerned.
Thank you so much Dr. Becky 🇳🇵🙏
Thank you for the hard work you put into your research.
Welcome to Canada! Thanks for all the amazing space work!
Thank you Dr. Becky. You are my go to for astronomical understanding . You present things with explacations that help us lay folk understand what is happening.
I wasn't watching at the start, just listening, and I had NO idea you were in a different location. audio was on point!
Welcome to Canada Dr. Becky!
I can't believe I missed out on a bunch of awesome people visiting the Perimeter Institute! I see that you enjoyed the record setting April heat while you were here lol.
Fantastic episode, your explination of the way the scientists eliminate all the options to come to their conclusions is fascinating, great to see the workings behind the curtains so to speak. And your clear passion for black holes is inspiring.
Welcome to Toronto Dr. Becky!
I don't usually watch the ads the whole way through, but that actually sounds like a really useful tablet!
Excellent as usual, Dr. Anxiously awaiting your next video. 😄
Thanks for another fascinating look into our universe!
Welcome to Toronto Dr Becky. Would love a video about things in the city that you liked. Hope you loved it here .
Dr B, keep going! I love your clips.
Thank you for showing those of us in the Southern Hemisphere love! 😍😛
Much the most interesting for me is the headline feature of black hole ejection. Really well explained, thank you.
