wait wait wait . . . isn't our supermassive blackhole THE heart / anchor point of milky way ???
supermasive black holes DO control the structure of galaxies to some extent . and the 2 are connected in more that one way . . so doesn't that make supermassive black holes the central "cores" of galaxies in a way ???
Correct me if I misunderstood what you said, but surfshark hacks databases to search for my passwords and other info right? Again correct me if I'm wrong, but isn't hacking considered a crime? Even if it's hacking criminal computers, it's still unauthorized access, if you kill a murderer, the fact that they are a murderer doesn't change the fact that you committed a crime, if you are going around hacking looking for info, you are just as bad as the criminals with the info to begin with
@@alexnorth2452 e
Is our solar system spinning into the black hole in the middle of our galaxy or is it getting thrown away from the center of the Galaxy?
Black holes are the result of a misapprehension by astronomers about the nature of gasses. mainly that they can NOT self compress under their own gravitation the math that claims that gases can self compress produces an infinite result from a finite set PERIOD! you can class this failure how ever you wish call it a violation of thermodynamics or a failure to adhere to proper unit rules the fact remains that you are producing something from nothing at some point in that model and it is BULLSHIT and you damn well know it.
All those references to "OUR" supermassive black hole were making me feel quite possessive and fond of the old boy. Knowing that it also has indigestion only intensifies the feeling of kinship.
I think it's safer to say that "WE" belong to IT.
@@nodrogdivad Sagittarius A* : Aww, thanks, children! _resumes snarfing matter_
@@Gyrfalcon312 no. You are the least productive species in the entire Milky Way
But it was really your mum
Old girl. It's a She.
The slow build up to the "your mum" joke @21:30 was just sublime, bravo Simon
the one time in the vid I wasn't prepared for it
"Yo momma" joke made me rewind and listen to it a few times. Simon's flow caught me off guard too. Fact boi is a legend.
Had to make sure someone had commented on it too.
I fuckin died
I still think it could be B…
I made up "Yo' momma so fat, if she put on one more pound she'd collapse into a black hole" years ago.
"More like a fat, contented cat napping peacefully in a sunbeam."
That's adorable. And horrifying.
Idk, black holes fit almost every major point of eldritch elder gods except for being sentient/ sapient-- and somehow that utter inability to care about things bc it's not sapient makes the idea of black holes that much more terrifying imo
Pretty much
Karl is such a Chad writing about black holes when they were just a mathematical theory while being accurate and while getting shot at in the trenches.. what a Mad Lad.
Not to mention Penrose! Who just finally received his Nobel prize for his work defining black holes through the math of Einstein's theories.
We may not be able to explore space in this generation, but we will pave the way for space explorers to do so. I wish our descendants the best of luck out there, I wish I could be there with them.
Unless puttin ends the world first haha

His video about Challenger and its crew was pretty good
Lowkey need a separate channel for Simon on Space!

Sounds interesting
Hes done it already :)
Is that where individual socks disappear into for no apparent reason?
@@davedavies8002 where?
One of the most interesting things about studying black holes is finding out just how much we DON'T know about the universe. There are things in space that simply defy the laws of physics & reality as we understand it - LIKE dark matter & where black holes really come from. More alarming is the fact that rogue black holes exist, not tied to any 1 position, but roaming freely through space, grazing on stars, planets, whole galaxies, & anything else they come upon. And we're still not really sure how physics works, or even if it DOES, inside a black hole. Who knows what else is out there that we can't even conceive of?
The universe is so mind boggling
@@ryleecaton1804 Isn't it? There's no way we can even wrap our heads around how BIG it is! I mean, when we look at the stars, we're actually looking back through time, because they're so far away. Billions of them may not even EXIST any more, but their light is just now reaching earth. Thanks for your comment.
The main reason why physics breaks down is because singularities don’t make sense. They defy the Pauli Exclusion Principle which is a quantum mechanical theory, due to relativity. Singularities have no dimensions, just points of mass. Quantum physics hates this. Which is why relativity and quantum mechanics do not work together.
We need a behind the scenes you and your team is just amazing with content I just don’t understand how you do it but thank you 🙏

Photographing the Super Massive Black Hole at the centre of the Milky-way, is equivalent to photographing an object 1cm across at a distance of 28,000 km (approximately). Pretty amazing!
It never fails to warm my heart to know that my favorite constellation Sagittarius has a super massive black hole in it. I love astronomy. It's so fascinating! Was watching another documentary lately and learned that our galaxy has eaten a lot of smaller ones. We apparently have a a sphere of the remnants of them surrounding our galaxy. Space is crazy. I love it!
At the risk of sounding super pedantic(sorry lol) the black hole isn't so much in the constellation as in the _direction of_ the Sagittarius constellation. Though one thing I find super cool is that our solar system is located in the Sagittarius arm of the Milky Way. I don't put any stock in zodiac signs, but I've always liked that I'm a Sagittarius so when I learned the name of our supermassive black hole and our solar system's location I was pretty stoked. Sagittarius is by far the coolest constellation. Also, most large galaxies do sometimes "hit" other, smaller galaxies and often even cannibalize them, taking in their stars and gas; the Milky Way is no exception. Some of these galactic remnants around our galaxy appear as sort of little smudges in the outskirts of the Milky Way. We've also got a few small satellite galaxies like the small and large Magellanic Clouds which are super fascinating in their own right.
@@semaj_5022 I was unaware that we lived in the Sagittarius arm of the Milky Way. That's really neat! I'll be the first to admit that I am not overly knowledgeable about astronomy. I just really enjoy learning about it. I appreciate the correction, thx for sharing =)
@@pyrethorn hey that's totally okay. I don't know a whole lot myself, though I really love learning about the universe and especially our place in it. I'm glad you found the info cool :)
@@semaj_5022 yES, I agree with your first sentence and it was bothering me that he ( or the writers) kept referring to the constellation of Sagittarius as a location. I came to the comments to see if someone else pointed this out.
I was born in December so I love hearing that the Sagittarius constellation is in any way special.
Despite how wildly terrifying our galaxy's supermassive black hole is; I actually like to think of it as the glue that keeps the galaxy together. I find that bizarrely comforting.
Technically they are the glue. Without them, we may not have been here
@@nappssnapps2891 without a spinning blackhole nothing would have rotation, orbits, therefore no gravitational pulls, therefore everything would stand still, lifeless. Is an interesting and scary paradox though.
Considering that there are galaxies with black holes of dozens of BILLIONS sun masses in their center, it's unlikely. Here come the theories about dark matter into play.
Nothing in our galaxy is gravitationally bound to Sgr A*. It could disappear right now and nothing would change within our galaxy, ever. Besides a few stars launched out.
@@nappssnapps2891 This is not true.
Scientists describing science equipmet: "a revolutionary piece of technology, light years ahead of its tme"

As a junkie for space and astronomy stuff I've gotta say this video was incredibly well done. Great job Geographics team!
Do you watch "sea" his videos are amazing!! Seriously impressive :) he only makes one per month but there really good quality and the visuals are great 🖒
@@davedavies8002 Oh yeah! His videos are amazing and so well done. They could air on cable and people would think a whole big budget production team is behind them. "Astrum" is another great channel along the same lines, though he explores a few more varied space topics, but his visuals an narration are crazy good. If you haven't watched him, I strongly recommend it! PBS Spacetime is my other go-to, for more high level astrophysics stuff.
@@semaj_5022 awesome :D thank you for the recoms 🖒
@@davedavies8002 Of course! Hope you enjoy em as much as I do :)
I watch a lot of black hole videos and a lot of “Simon” videos. This is really an exceptional production. A big part of Simon and his staff’s class is making stale topics fresh. This is an oversimplification but you know what I mean. Great job, everyone 😎
stale?
First of all blackholes are never a stale topic and actually thats all I really had to say
Exceptional except for the errors I suppose. Simon states that the Sag A* has a radius of 22 million km and then states that Sag A* would extend to Mercury in our solar system…. Sun to earth is 1.5 million km so the distance to mercury is way less than that. Also nothing except research papers are a product of physics. Physics describes nature so things are a product of nature such as Sag A*. Also all black hole leak and the leaking stuff is Hawking Radiation and overtime they can leak away completely if no new matter is accreted. So given that what Simon is describing is jets of matter shot out the poles of the black hole because of magnetic fields and charged particles.
Anyway he’s just listing facts and reading a script with absolutely no understanding of the topic. So that makes it a crap delivery.
@@bekka4621 idk... my black hole says it's 10 x10^4 Billion years past expiration...is it stale or not? I'm scared to go near it
I love astronomy. So, it goes that Simon will start YET ANOTHER channel. So we need to suggest names. Mine: Stars & Shit That's Cool
He won't. He needs research for this. And the information might not be enough on some planets or stars.
I see Simon so much on UA-cam I feel like I will bump into him in my local supermarket sometimes
Imagine, this is all we've found of our universe while stuck on our little planet. Imagine what we'll discover when we can finally spread among the stars.
may the human race not find any other life form EVER. If there is a small and hyper voracious blackhole that is surely the human race.
The successful deployment of the JWST is the most excited I've been since my son was born. I'm so excited for mid-June when we start to get some images back!
Thank you! You answered the one question I haven't heard explained in any other video or article I've read until now. What the * in Sagittarius A* was there for! Awesome job :)
Loving the "your mom" jokes! Brilliant!
A non-spinning black hole would have an accretion disk as well. The disks arise from the conservation of angular momentum of the matter falling into the black hole. So, as long as the material has angular momentum, it will form an accretion disk for any black hole.
This is one of many reasons why science is so captivating.
I love the way you sneaked in Doctor Who story titles in the chapter headings - e.g. ' The Sun Makers' 'The Armageddon Factor' 'State of Decay' !
This video I found to be of an exceptional quality. I usually like most videos of this channel and its sister channels, but this one I thought was even better. Well done. I wish you good health and much energy to continue doing this work. I appreciate your every effort.
It was terrible. Most of the graphics had nothing to do with what was being said ... just random spacey pictures. And the narration ... every 1st year astronomy student cringed.
@@MrTexasDan Ok "Mr. Texas" I bet you're super educated based on your state's education system...yikes. imagine being from a redneck shithole like Texas and thinking you ever get to talk down to someone about science.
Simon, I’d like to thank you for putting out great content. I listen to The Casual Criminalist religiously when I’m at work. When people ask me what I’m listening to, why I’m so pale and gaunt , I tell them it was the tea I’ve had , or maybe the sandwich at lunch didn’t sit right. Hang in there fact boy. I’ve used up my comma quota for the year in this very comment . Cheers
the radio space telescope located in Green Bank, WV is named for Janksy. it is so sensitive, no wireless devices are allowed within miles of it- no cell, no wifi, no garage door openers, no radio emitting anything. it can even pick up the collars on the local flying squirrels.
Executive: "Don't bring me problems, bring me solutions!"
Science, after it gets done laughing: "You don't want solutions. You want critics to shut up."
Holy hell, cracking a yo momma joke, that made me scream!
Thank you for this video Simon...you put it together so well...very, very interesting...
A different topic for your channel, but very interesting. Excellent show, as usual.
It will be very interesting to see what the JWST finds when it looks in this direction.
While I'm not 100% and could be very wrong, I think the JWST won't do great on this because of the sheer amount of light between us and the center. Its also more tuned for redshifted waves that no other telescope was able to see, meaning its better at super far stuff rather than visible light.
Still extremely powerful, but the wrong tool for this job
Lots of gas blocking the view
@@BaioWithMayo actually the JWST is an infrared telescope so it can peek through alot of the dust and stuff. That's what makes it so special
@@nappssnapps2891 oh thats awesome then! out of curiosity since im not fully educated on this, I did see that it has less visibility for higher frequency light than Hubble, so for things closer wouldnt that make it harder to see/not functional for JWST?
the flip side I guess would be that it can see the light regardless, and IR is better to see more specifics clearly?
Amazing that something so far away has been researched this thoroughly ... love science.
And now I have to listen to Muse's "Supermassive Black Hole" on repeat.
lol , that song was rolling around my head as well
As a Doctor Who fan, I appreciated the in video titles all being classic Doctor Who serial names.
This was one of your best videos... well done.
This episode is so well written and presented!
Another Excellent! Thank You Simon. I love your coverage of Space. Very interesting and Educational.
Nice one. I liked this! Thanks!
Another great video, beard looking majestic as always
Was waiting for Simon to break into song with muse 👌
I'd love a lot more cool scientific stories like this or biology. You could have a bunch of stuff about stars, planets and what not. There is a world where you can make a proper 20 minute capsule on various animals/plants/other.
solid video, i enjoy these
CYG X-1 is shorthand for Cygnus X-ray Source 1, so named for the constellation Cygnus the Swan it lies in the direction of.
And Rush made an awesome two-part song out of it too!
Thanks for this. Been diving heavily into dark matter/energy theories recently.
What have you learned?
Fantastic video. Gotta say, the your mom joke was so good, you should have just mic dropped and walked away right there. well done!
You uploaded that the momment I was reaching the center of milky way in my space game Elite Dangerous. You're a magician lad
Man, this was cool. Simon you should do a video on the Triangulum galaxy
Your Channels are great!
Thank you fact boy! 🙏🏾🙌💯
Wicked! Just subscribed👍🏻
Maybe the reason they’re at the center of most galaxies is that supermassive black holes are wormholes to other galaxies.

Great video
1.) S-2 would not orbit "clouds of dark-matter" in any way similar to its observed behavior.
2.) When we are able to calculate initial collapse phenomena, we will also be then able to back-fill/map most of the history to find its long-lost intervened progress as CMB-projection.
3.) Watch for "amazing" & "never-guessed" (etc.) 'excessive' lensing 'fairly centered along gallactic-arm (expansion-) filaments.., which we actually orbit.
4.) 'Betcha' a quid...
Great vid as usual from the Whistlerverse! Love the astronomy vids (and more) as they feed my curiousity well. (Omnomnomnomnom)
My science side has one pet peeve though - could you please please please say "Hypothesis" rather than "Theory"?
Especially when discussing scientific research or anything scientifically related?
Please?🙏🙏🙏
4:30 I never pass up a chance to use the term "Astrophysical Jets" in conversation, even more so when explaining the Phenomenon of Black holes. I guess Burps/belching works too.
Thank God for Simon!!!
Good video 👍
I love this so much!!!
Nice editing
Mr. Fred Rogers "You can never go down the drain." Sagittarius A "Hold my beer!"
51 Peg, Sag A Star, IC1101, Vela Pulsar always gets my clicks 😂
Maybe do one on the two telephone physicists who discovered the cosmic background radiation field next?
Using Gravitational Waves to study black holes has a limitation - size of hole to be studied is proportional to length of detector, so LIGO & GEO can only study black holes a few tens of the size of the sun. We will need massive solar system sized space based detectors to study the largest black holes. Great video on this by Dr. Becky
Great Vids! keep up the good work!
Please, and I think I speak for everyone, start uploading in 4K!
Just wanted to point out a few things. When we are looking through space we are also looking back through time. The quasars that are seen are black holes that were active because their galaxies were still in their early days of formation, therefore the gas and dust in its proximity had yet to be corralled into the disk shaped spiral galaxies we see today. When a galaxy is forming most begin as just dense pockets of gas and dust but thanks to inertia and the conservation of energy most objects in space (... okay probably all objects in space) begin to rotate. In a galaxies infancy it’s elliptical and many spiral galaxies that collide also tend to form an elliptical galaxy as well (mainly due to the effects of those two galaxies and their gravitational stress they exert on one another). Elliptical galaxies are where there is small amounts of rotation but since they are generally primitive (again elliptical galaxies are very far away, the further we can see, the longer ago that structure existed) the galaxy we see very red light, hence why they look orange (and redshift). In a spiral galaxy that central black hole blasts those super heated x-ray beams and matter at its poles, further compressing the gas in the galaxy into a disk spaced spiral galaxy, starting a swath of new stars to be created, making the spiral look blue and bright because it’s creating very massive stars that have very short lives but emitting very bright blue light and of course many sun like stars but primarily red dwarfs (which is why spirals have so many colors compared to elliptical galaxies). Elliptical galaxies are often called "red and dead" because they lack that star forming pressure those polar jets centralized supermassive black holes create. No jets, no centrally compressed spiral, few new stars, few huge blue super giant stars (they live for a very short amount of time; millions of years instead of billions like our sun, and then of course the trillions of years red-dwarfs will fuse for), more lower mass red-dwarf stars that will exist far longer than their larger siblings... hence why elliptical galaxies are aptly called red-and-dead.
Unsolicited "your mom" joke killed me😂
I hadn't heard about the dark matter speculation. It would be very interesting if Sagittarius A* turns out to be a huge hunk of dark matter!
"or B) your mom."
I died lmao well played.
How can they see or know how does the black hole behave if a given moment travels 26K years to reach us
The internet fact boy is filling my mind with trivia knowledge again.
I agree with ya
18:55 - “only one theorized object was capable of being so dense” …. Simon Whistler 😂
The best compliment I can give Simon especially when he produces such great content is that his videos are very reminiscent of "Hey! VSauce Here!"... To me at least. And if you only knew how many times I binge watched not just Vsauce but also VSauce 2 channels, you'd know just how much of a compliment this comparison actually is...
Excellent spacey stuff.... and a free mum dig!

The "burp" from a Black Hole is known as a Gamma-Ray Burst. It would be absolutely catastrophic if it hit Earth. And we'd be lucky to see it coming.
