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
@@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
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.
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).
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.❤
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!
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! 😊
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.
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!!
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!
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.
@@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.
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.
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
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.
@@JamesJordanson 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.
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!
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
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
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.
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.
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.
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!
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....
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.
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.
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
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 :)
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.
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!
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.
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.
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. :)
So my daughter walked into the room as I started watching this video. Next thing I know, she gets this wicked smile on her face, and starts playing "Supermassive Black Hole" by Muse. I'm kinda proud to be honest.
Great video as always, but a slight misspeak . You refer to gamma rays as having the "highest wavelength" (around 12:37) but I think you mean highest frequency (i.e. shortest wavelength).
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.
Hit the wrong button, but I was trying to say that you and Neal share the same childlike excitement and enthusiasm for the Stars (astrophysics) and you help the rest of us to keep looking up this is he does. Is there any chance you could do something NDG?
Halton Arp showed this phenomena a long time ago. He even has a catalogue of space images showing quasars being ejected from galaxies. Look up his book called "Seeing Red".
Becky, I heard that you may be coming to Huntsville, Alabama, shortly, and I'd like very much to come hear your lecture. I live in Birmingham, just south of Huntsville, and it would be a rare opportunity to see you. I hope you get this note before I miss you. Thanks, and have a great day!
Ahhhh, I am so upset right now! I live in Waterloo and I didn't know you were coming! I had final exams this week so I probably wouldn't have been able to meet you anyway though :(
Wait! Huntsville, Alabama!? That's where I am! I hate that I missed that you were here! I hope you got to meet up with Destin, from Smarter Everyday. He's from here as well. Man, I would have loved to get an autograph in my copy of your book! Anyways, I hope you enjoyed our little sliver of the planet. Hopefully they showed you the good places to eat!
It's reverb. Echo was originally added to music using a long pipe with a speaker in one end an a microphone in the other, the distance between the mic and speaker determined the delay time. To get regenerated echo the output of the pipe was fed back into the speaker repeatedly until it faded. Reverb was achieved by recording in any room with hard surfaces allowing the sound to bounce off the walls and floors. Starting in the late 1970's effects were added digitally. Even today most reverb selections allow choices such as "cathedral" or "small room".
Sorry if this has already been mentioned but the "previous video on the effect of removing the Milky Wy’s supermassive black hole - " has no link in the description. Awesome video though! Its amazing that the ejected black holes spawned star formation in their wake. Would these regions be considered new dwarf galaxies or part of the original? Space is awe inspiring.
Hi Becky you got to be the most exciting girl that I had ever found in RU-vid. Your are the coolest one and I like all your videos. They are all so interesting and informative. Keep on posting new videos.
Hi Dr Becky, I think that I have been ejected by a massive Black Hole or------- been visiting another Universe because I've had my Laptop hacked twice -- yes twice! By some scabby scammers and am only now getting things back to normal! So it;s good to be back watching your YT issues. I just love the idea of Black Holes being ejected by a Galaxy ie. Spat out ("You're not welcome here any more"!)!🌌
Maybe it didn't like the other two black holes and exited the galaxy? If, as Dr. Becky states, there was a third black hole that came in, that third black hole might have interrupted the other two: "Now, children, play nice or it's no new accreted matter for either of you!" Who knows, maybe black holes do think, on a cosmically large scale we can't even see.
Questions, can JWST can see tru the galaxy and see the other side of it??? And it will have new observations of previous black holes to get new data on them???
I was in Türkiye on the 23rd and we were out in the middle of nowhere so the stars looked fabulous. I pointed out Venus and the toenail moon to the other people on the tour... and that's how I found out which of them also watch your channel!
The ejected black hole got me thinking about something. I'm aware a number of galaxies have been found recently with no dark matter. Do you happen to know if they lack a super massive black hole at their core?
Wow, I'd love to see you in Huntsville. My father worked there back in the 60's. Let us know if you'll be speaking at an event that the public could attend.
Did not enjoy reading The Three Body Problem but it was a horrifying glimpse at what life might look like clinging on by fingernails in an unstable system.
I'm curious what you think about the new image of the M87 black hole. Some online comments were criticizing it, but it seemed reliable to me, which is why I'm curious for expert opinions.
