What a hunger in Dr Becky's eyes when she thinks she may get a pet blackhole 😂
Imagine how awesome it would be to have a real black hole so close to us so we could study it :O :O :O
I KNOW 😱😱
Dark Horizon mission 2050?
Donald Trump is a huge dark vortex sucking in Democracy like a Black Hole. Close enough?
@@VA7SL Why bring a shrill, boorish specimen of the lower internet phyla into this?
Adymn Sani, what? no more on the edge than some of the commentators
I could listen to Dr. Becky all day. Passionate delivery. Makes the complicated simple! 100% love her videos! Fantastic work Doc.
Stop everything, guys! Mercury is in Gatorade!
=:oD
Oh, I wish I had a telescoop. I'd be able to get ice cream without leaving my computer chair!
As a Dutchman, I find that hilarious...
@@martijnvanweele6204 Haha, so that's how you spell that word, eh? :D
@@mytube001 Yup XD
@@mytube001 Indeed we spell telescope that way :D
best space joke i heard ALL DAY!
Dr. Becky, I just wanted to say that your energy that you exhibit in your videos is contagious. Always enjoy watching, even the bloopers and the after comments. Keep up the great work.
My friend shows your videos to her 6th grade class without watching first, and tomorrow, those kids are gonna go bonkers at "bullshit." I love it.
I definitely said “bullshirt” for all my fellow Good Place fans
Dibs on rights to use it as a power production reactor!
So I can look forward to 'what does a black hole taste like?' in a few decades then? 🤣
Yeah don't bring it to Earth
using it's hawking radiation, you could probably power your laptop but overall, it would suck.
Im a fan Cody!!
That's beginning to sounds some First Order stuff right there...
Discovered you on JMG’s Event Horizon channel and you were awesome! Subbed immediately and now you’re a favorite. Thanks for the great content!
Same here!
Clearly, everybody in the same boat as you need to subscribe to the Sixty Symbols channel because that is where all of us who have been following this channel from the start came from. Dr.Becky came to everybody's attention when she scored the outreach fellowship over there. Sixty Symbols and the chemistry channel Periodic Videos were the nucleus of the whole enterprise that came out of Nottingham University under Brady Haran and team.

A great episode!!! One of the best ever!!
G
Love your videos Dr. Becky
Very informative and interesting.
Great work!
My favourite bit of that paper is that their diagram of the black hole is actual size.
Other than that I really love that they present something actually testable. It's not just an idea, it is a plan.
Saturn is my favorite planet as well- I discovered it Easter Morning 2016- with two of my little miniature poodle puppies playing under my feet and the legs of my telescope. It was a great accomplishment for me as I have no formal training whatsoever in astronomy- sort of a "hunt and peck" astronomer. My first observation of Saturn was in 2013 when I was at the Lowell observatory in Flagstaff Az. I told the astronomer there I didn't think I could ever do this- he said sure you can!! I just found M41 the other morning. Thanks for the great videos!!!
I really like the length of the video, and appreciate all the work that goes into research and organising it to make it understandable for us. Hope to see you witu your own series on tv in the future. We need more science, and meaning. Scientists should be more visible in society. Some great images and graphics here.
Great episode, wonderful stuff.🤩
Lovely to see your enthusiasm, cant wait the next wednesday
Great video! We've also been in a new (well, different) house for a month or so and are still surrounded by unopened boxes, so the "clothes in suitcases" bit at the end was also fun to see. Good luck with it all. I shall think of black holes while I'm trying to sort out the stuff in the garage: a nearby one to chuck stuff in would be quite handy.
"the solar system's pet black hole." You made me laugh!
Do not try to pet it.
LOL.
Love the new "Breaking news" music segues!
You are my favorite youtube online astrophysicist.
DrBecky, you are a fabulous presenter. Highly energetic, easy to listen to, and explaining science that makes sense to the non-degreed - like me. Thank you.
Nice channel doc, keep it up!
Very cool video. Thanks Dr. Becky!
I watch your show for a few reasons. First and foremost, you are a brilliant scientist. I don't understand everything you're talking about (my degree is in computer science, not astrophysics) but I add to my layman's understanding of the universe thanks to you. Second, you have insights and the ability to make them understandable to those of us who don't have advanced physics degrees. And, third, I love your sense of humor! Keep up the great work.
I'm not going to use the timestamps, but I really appreciate that you do that. Other people on CZcams don't and it drives me nuts when they end up talking about a topic I don't care about and want to get to the one I do care about.
Same here. I think having time-stamps removes most of the frustration viewers feel in not knowing when the video gets to their particular "good part"; with the time-stamp, it's like, okay it's coming about that many minutes in, so I don't have to wonder or fret; just listen for a bit to some intro "almost as good parts".
Alex Ornelas wherevare these timestamps?
Timestamps are in the description.
You must really hate the gamer nexus news videos. At least he posts the topics on the left, and each story gets a blue progress bar to show how far into the story he goes. But, yeah, would be nice if more provided time stamps.
@@jackielinde7568 nah that would be fine. I'm specifically talking about some of the "true" horror youtubers that would mix paranormal in with things that could actually be real, but they don't include any good way to know how far to skip to get to the next story that isn't paranormal.
Love your passion. Keep it up.
Hi from Montreal and thanks for mentioning our awesome planetarium!
Hard to miss: it’s right next to Olympic Stadium. 😎⭐️🍁❤️
Hey! Good job!!! My 13 yo daughter is finally getting interested in those stars! That's what got me interested at about 7, and even though I'm not an astrophysicist, there's nothing more suited to get the brain working than thinking about the vastness of space! :) Thank you!!!
Excellent video and subject matter! Especially the Primordial Black Hole theory. It makes sense and answers so many questions. Plus, it would be pretty cool to have one close enough to study! I wonder how far would one have to remain from the event horizon and still be able to study it close enough to get all we can about it?
P.S. I love watching the "bloopers" after the video. I have to admit that most scientists are rather bland. You are not! I love your enthusiasm! Rock On, Dr. Becky!
Your eyes look fantastic from this angle / lighting
Your fanbase might be small, but we really love you. The way you show your feelings and biases makes you more credible and easier to trust. I wish you where my little sister.
Very interesting. I like it straightforward with it as basically explained as possible.
Such enthusiasm for space. Very cool.
You are Awesome, thank you for your content
I love your videos. You're incredibly knowledgeable yet you make it accessible to the laymen like me. Not to mention that you are incredibly cute and very passionate about your subjects which make you a delight to watch.
I was reading an article regarding this planet 9 theory, clicked on your video first as I have bookmarked one more video of yours regarding how we calculate speed of light, I must say great job on this video given the complexities you have to explain. Thanks a lot. Love from India 🇮🇳
I love the "on the fly" corrections!!!! I follow physics very close but I didn't make the connection between the two studies. You are awesome.
You made me look up "pipped at the post". Darn you, Dr. Becky, for making me learn something while I'm learning something!
6:22 I met Dr Mather in Hawaii 3 years ago. we sat on a bench by the sea discussing Webb and the stars for an hour.
"Moony McSaturnface" LMAO!
At that point i fell in love with her. :D
I love your enthusiasm, and how you feel about astrology.
i also love to hear you ue four letter words!
I hate autofill
Great! As soon as I heard the primordial black hole idea, I was hoping you'd cover it.
I don't understand why this hypothesis is being given so much attention.
The old adage in medicine is "when you hear hooves, think horse, not zebra".
In this case, it is more likely that there is a massive, distant low-albedo planet out there than a tiny black hole.
Yes, it's an exciting idea, but so are out of body experiences which actually turn out to be hypnagogic sleep paralysis.
Again, when you hear hooves, think horse, not zebra!
As Dr. Becky mentioned, the odds of the gravitational source being a primordial black hole or a captured planet work out to be essentially the same. A captured planet may be more horsey, but that doesn't mean the answer can't be stripey.
If nothing else, a primordial black hole should be easier to "look" for with current available technology. (But I doubt Dr. Becky will be boarding a spaceship with her "I (heart) black holes" flag to visit it in this lifetime.)
Forgot to add: And a PBH would be explain the gravitational microlensing.
Your enthusiasm is very contagious Dr Becky. I really wanted to study astronomy and cosmology but unfortunately the University I attended cancelled that course for various economic reasons, they do however still have and use their observatory that has a beautiful 26 inch telescope and thankfully Sydney ( Australia) does not have real bad light pollution. for now most of my star gazing is done with a pair of 25x100 binoculars and since I do a lot of remote travel I get sky's that have no light or even much atmospheric pollution, when you can read a newspaper by star light you know you have a great sky. It even gives me a slight vertigo at times.
I also think that planet 9 could be some sort of black hole, it just makes sense but I think it will be a long time before anyone actually finds it and I think it will be by accident when a space ship slams into it... oops.
Thank you again!
Gotta love how enthusiastic Dr. Becky is when talking about the primordial solar system, um I meant the primordial universe, I think? Great video as usual................ :)
I was absolutely thinking Moony McMoonface and then you went out and said Moony McSaturnface and I died
Some exciting stuff!!
Fred
Thank you for keeping it real finally someone no afraid to tell you like it is thank you for all of the great videos you’re making this journey of learning about astrophysics etc so much easier and much more fun, space on. Also u might want to explain to the viewers that BH aren’t really that dangerous that the gravity is no different from planet mass BH to planets just a thought because I know I always thought they ate up everything lol.
It does seem rather odd that any old space rock gets moon status due to a quirk of its location, but we're so precious about what counts as a planet because we don't want there to be too many of them.
Very interesting and informative!
Your mentioning the Mercury transit reminded me to check for ISS transits of the sun near me, and there's one passing right over me on October 29th! I'll definitely have to try and get a shot of it.
I love how every video is like sitting down and having a conversation with a friend. A smart friend, ok, a smarter friend than I have, but still.
as an isaac arthur fan, i can't help but imagine how a planetary mass black hole could spur development of the outer outer system. it could be a huge source of energy, eventually we could even build a shell around it and turn it into an artificial planet.
"MUSE" and "supermassive black hole" in the same segment, nice!
Awesome video keep doing that. You've got the right "i-dear" lol
Damk becky, you're breaking my poor head with all this info
Thanks for the explanation. This really is an interesting idea. when people think of black holes they imagine all consuming monsters and that in our own solar system.. well that could sound a bit scary. But i like the term 'our own pet black hole' sounds kind of cute :-)
Moony Mac Saturn face, Dr Becky you are a laugh riot. You made my day.
"What if Planet 10 Is a Primordial Black Hole?" - Me, the Pluto fan.
In that case it would have to be more like planet 15 or 16
🤜🏼👍🏾👍🏻👍🏼👍🏻👍 👉🏼
Didn't it get its planet status back?
@Carlos Saraiva I thought it was because it's unknown AND supposed to be 10 times the mass of Earth (plus the 10th planet as a "bonus").
@Carlos Saraiva Gotcha. I agree wrt names.
You made me laugh 😂 good video!😀
Totally off topic, but I was wondering what watch you wear?
I loved it when you called 'bullshit' lol...casual astrophysics.
That was extremely informative, well done . Never knew that black holes had a size limit and spat stuff back out, thought they just got bigger and bigger with all that extra mass and thought the universe would all be eaten up by a bigger and bigger one [not this week though] and that would be the means of the next Big Bang [not holding my breath for that though] a Higgs Boson? Mind boggling it seems that Planet 9/ Black Hole is 46,500,000,000 miles from the sun!!! That is quite a long walk!! Have worked out how to confirm whether it is a Black Hole or not, send Wallace and Grommit in their space ship, for that seems to go anywhere instantly.
That intro, subscribed in 2 sec.
I had already heard about this paper, but this explanation was WAY better and more detailed. Dr. Becky really is the best!
Also, come on, there's 80+ moons. At least ONE of them can be Moony McSaturnFace.
Oh My Universe! love it!
"Solar System's Pet Black Hole!" 😅
Sun : ThugLife
Black hole: Left the chat.
Thanks! You got 11 🌟 out of 10 for this.
Hey Becky - two things that confuse me about this. If they detected unaccounted for gravity lensing, then finding the object should not really be a problem should it? They know where the event occurred with high accuracy due to measuring the lensing event so wouldnt it be pretty straight forward from there? Look in different wavelengths at that spot and you would find it?
With the black hole idea - Shouldnt we be able to detect the x-rays being released from the accretion of matter around it? Even if only small amount of matter was being accelerated and then emitting x-rays that should be visible, being fairly close in cosmological terms. What am i missing?
You wonder why we haven’t observed and found a baseball sized object 500AU from the Sun?
That was sooooo good. Clickbait worth clicking. Thanks, Becky.
description of horoscopes.. clicked like !
Hey, I have bought a binocular with 10-22x50, what can I watch with them ? Would you kindly let me know?
Could I use a pinhole viewer? IE: a biggish box with a pinhole and a sheet of white paper on the opposite inside surface of the box ?
Will it have enough detail to image mercury ?
Protons per teaspoon is my new favorite unit of measure.
Nice analogy of the race track and even better expletive!! Lol
A few days ago I was taking my rescue dog Rosie for a walk to take a wee at night and I looked up and spotted a large orange light in the sky. I also rushed out of the house yrs earlier after listening a British broadcast news that a orbiting satellite was carefully being brought in to burn up in our atmosphere. I just got out the house in time to this pass over and it was streaking and glittering and was an amazing sight. I told my mum but couldn't get her to leave Corry so I ducked outside on my own and just saw it there on my own thinking I hope millions see this event because it's history. Can't wait for The James Webb telescope to come online because this one is stunning and reveal so much science about so many question we lover of science will surely offer us. The delay is because you can't fix like the famous Hubble Trouble had because it is a lot further away. We wait with baited breath. I don't know what the orange light was but it remained there for a long period of time. It sure weren't the moon. I watched the eclipse of the moon and it turned into a beautiful tangible red colour. Another amazing sight that I will never forget. It looked like I could literally touch it. Strange but real.
You have such a talent for science communication.
Thank you :)
Dr. Becky, you don't know how many times I've lost my keys because I was too busy watching Mercury going into retrograde instead of paying attention to what I was doing.
Also, pretty sure the newspaper article was either satire or irony. Also, it sounds like a story that The Onion would publish.
23:40 I saw a suitcase in reflection 😂💼
8:58 I had the video playing in the background when I heard this bit. Instantly two thoughts occured.
First: Oh this has been done before with sub-optimal results.
Second: I have the perfect name... only for Dr. Becky to specifically shut my perfect name down... back to the drawing board.
Wonder if a reasonably proximate black hole would help with the halo drive...a bit?
I'm glad that it has stopped raining here in Northampton for a couple of days, as it is now possible for me to look at my favourite bits of the night sky when I get up in the morning (very early - about 3.15 a.m, but 4:15 a.m in Ollish time, which is the time that we, the Ollish, go by). I like seeing Cassiopeia, the Pleiades and Orion's belt particularly. It took me a while when I was in New Zealand many years ago to notice that the horsehead nebula was above instead of below where it appears here.
Looking forward to the suspected extrasolar comet in early December - dunno if it'll be easy to see without a telescope, but am looking forward to more spectral analysis of it.
It would also be awesome if the terrascope would one day be testable...in the meanwhile, looking forward to the James Webb telescope getting deployed. They can take their time with that, on account of the difficulty of servicing it where it will be deployed, and also the difficulty of deploying it.
I can also assert that I first heard of your wonderful channel on John Michael Godier's Event Horizon show.
*_...also, if the mass hole is in retrograde orbit, then its time-of-passing-effect is reduced ergo its mass may be 25× greater than your/their estimate; I called it, 'Pluton', in 1984..._*
#WeatherRantOn What would I need a telescope with a solar filter for? There hasn’t been a cloudless sky since the effing heatwave in July! #WeatherRantOff Thanks for another great episode again, Becky. I learned stuff again! 👍🎉
talking about black holes, the white shirt tho ... can't focus :p as always exelent video keep the good work !
Nice work! Any ideas about the distribution of primordial black holes in the galaxy?
Hawking Radiation Idea makes any still existing a question assuming Hawking radiation exists.
Happy new wardrobe day!
Thank you for the discussion on the possible primordial black hole! At 14:50 you state that Neptune's orbit is very elliptical (a high eccentricity). My books state the opposite, that Neptune's eccentricity (0.011) is about the same as Earth's (0.016). Were you thinking of Pluto and conflating the two? Nevertheless, this was a great video!
Those eyes. Wow
If it is a primordial black hole, Hawking's suggestion of using small black holes to solve our power problems becomes possible radically sooner. It's bigger than what he suggested which might complicate things but likely not as complicated as creating your own from scratch.
When you used your plant to illustrate the size of the (proposed) primordial black hole, are you saying that it is actually SUCKulents in space?
made my day :D
dad jokes 101. lmao
"Drop in any time: Bring your friends." - Pennywise
Could you post something on the MUSE technology
Dr. Becky - A serious question:
What do optical telescopes use in their sensors? I'd assume that the standard RGB sensors we think of in cameras would destroy too much of the intermediate wavelengths to be useful, so how do they capture the full spectrum of all the incoming light for every "pixel" in the image?
Images are made with CCDs. Filters are used to look at specific bands of color. Images made with several different filters can be combined to get "full color". Spectrographs split the light up so that different colors go to different locations on the detector; the color information comes from the intensities at the different locations.
How could anyone timestamp Dr. Becky?! It's all about the stuff BETWEEN the timestamps that make her the best! Loving the longer videos also.
Merci
So I guess my idea of naming the moons after The Beatles is off the cards. Fantastic episode.
Now i want a pet black hole too! :D
CZcams is a nightmare for notifications. I only just heard about your Exoplanet video.
@dr becky....Is it possible to have a moon around a moon?
