"Trust us, Black Holes aren't that scary!"
*Proceeds to play the recorded sounds of an eldritch horror.*
"be the guy who first recorded the sound"
Scientist 1: Guys! Guys! i managed to record a audio black hole, and convert it to it into a range about to be heard by humans"
Scientist 2: Awesome what does it sound like?
Scientist 1: Ummm.... Hell?
which is the form of a black hole, a sphere or a flat hole?
or why does the black hole exert an inward rather than outward centrifugal force on the accretion disk?
@@Ezekiel903 Considering how mass works when compounded and pressured, it'd be a sphere. A hole would be something like a theorized wormhole.
@@Ezekiel903 As for why there's a disc around some blackholes, it has to do with gravity and the rate at which it is spinning. It's why the gas giants have rings, it's why the solar system is going around the sun, it's why the moon goes around the earth. All these objects are spinning at enough of a rate to influence the objects around them, but the gravity from them isn't explicitly strong enough to just outright force them into the same spatially occupied location.
Same goes for blackholes. They spin, creating the mentioned discs in the video.
Mostly harmless. Don’t forget your towel.
Meet you at Milliways, but don't try to order salad. ❤
And let's not forget that the answer is 42.
The earth is the center of the observable universe because, well, that's where the (known) observers are.
Not a strange concept that what you can see is centered on you. The opposite on the other hand would be very strange indeed.
I think it’s like how you can’t see the curve of the earth because of the size difference between us and the earth. Even the size of the observable universe still isn’t large enough for us to be able to discern the true shape of the total universe. More testing is recommended.
It's so strange that the point of view of everything I see just happens to align exactly with the location of my eyeballs... it must be a miracle!
@@davidva8694 There were some tests done using triangles on million light year scales (I dont know exactly how it was accomplished though, the scientific papers are beyond my level of comprehension) and there were no changes, the triangles were perfect 180 degrees. If it had a curve, the triangles would be more or less than that amount.
Haha, that's a great way to think about it! From our perspective here on Earth, it definitely feels central! But is there really a center to the universe at all? That's a question scientists are still grappling with.
Hearing the black hole at the end of the video is amazing.
0:40 - Chapter 1 - Dead stars in the night sky
3:15 - Chapter 2 - The earth is closest to the sun the summer
5:20 - Chapter 3 - The observable universe is the universe
8:45 - Chapter 4 - Black holes are terrifying dangerous
12:50 - Chapter 5 - In space no one can hear you scream
Hey what's up buddy!
Thank you!!!
Hmmm... trillions of souls languishing in hell for all eternity? I just heard space whales....
YES SPACE WHALES!!!
It would make a good extreme metal intro tho 🥳
I heard that galaxy plans to send a probe to Earth looking for humpbacks... 🖖🏻
Where's Admiral Kirk when you need him?
Space whales? According to the Doctor, there's only one left. Cheers....
Anything in the Universe labeled "mostly harmless" reminds me of HHGG.
Don't forget your towel. ❤
@@julianaylor4351Towel Day is coming up, May 25!
"The whole [radius that could be dangerous around a black hole] is only about the size of New Jersey" OK but have you been to New Jersey? That state is scary 💀
If you escape the accretion disk do you wind up with a fake tan to show for it?
@@HeavyTopspin and a STRONG desire to fist pump!
I'd rather end up in a black hole than in New Jersey 😂
@@HeavyTopspin depending on which side of NJ, you could end up in the Hudson which is much.. MUCH worse than a black hole
@@venomenace😆😂🤣
The sound of the black hole is both fascinating and utterly terrifying.
If I were to ever see a black hole, the fear isn't necessarily from the danger is poses to me, but the inability to comprehend it. We are talking about an object so dense, with gravity strong enough to bend space and time. It's just really crazy to try and wrap your head around the idea and presence of such an object. To some degree it might even feel like all the knowledge of the universe is locked away within, unable to be observed.
Granted, it probably only feel like that for a few days, and then I'd probably get over it. Because in reality, stuff like this just tends to be scary till you get used to it. Then the novelty wears off. I mean, even stars when you actually think about them... are pretty crazy and yet everyday we see one right there in the sky. It's so common, that you rarely even think about it.
That's because we see them from so far away.
Imagine looking at something that eclipses your field of view in every direction, and when you look at it, you can even see the back of your own reflection.
Except, there's no time. Only motion and attraction.
If you'll ever get that close to a black hole, the grinding motion itself has already beamed you with so much radiation that you wouldn't probably even notice that you've died.
Time is only human made concept to understand motion.
If you understand neutron stars then the black holes ain't much different.
They're just densely packed objects that spins really fast and also crushes you like a lemon due to gravitational weight.
I'd say they're like one gigantic atom. Can't get any denser than than and that also explains why they can get bigger and has a mass.
I think No Man's Sky did this well, as you can only get so close to Sagittarius A before the background radiation becomes too intense, as you earn that game achievement.
To be fair, our own sun and earth generate gravity strong enough to bend space and time. Orbits are essentially objects moving in a straight line through a curved spacetime. Black holes accomplish the same but on a much more grand scale.
"gravity strong enough to bend space and time."
Bend space-Time is the gravity.
You forgot #6, people think the world is flat
In an infinite Universe any point in that infinite Universe could technically be considered the center.
Also in an infinite universe, there are infinite exact copies of everything.
@@digitalfootballer9032 and infinite copies of every possible variation as well. Although it can be assumed that most variations wouldn't be stable. Usually the systems would collapse into more chaos, until a stable form could be reached.
That also could be true of a finite universe depending on its shape.
@@adamredwine774 People who believe space is finite have the same tone as flat earthers.
@@kamron_thurmond It's literally an open question in cosmology... people who speak outside of their depth of knowledge are why there are flat earthers in the first place.
Never knew the Universe was a "Sideproject"!
1 million subs. Congratulations Simon🎉🎉
This is his most underrated channel, in my opinion.
@@Marykate465Astrographics would like a word. In fact, I'm surprised this wasn't posted there, or at least given a shout out.
In my personal opinion, a Quasar is probably the most terrifying thing in the galaxy, or the known universe.
I can think of a few things on Earth that are scarier than Quasars.
Just a heads up: There's also something called "Seasonal Lag". It takes time for temp changes to effect our atmosphere. This is why the coldest & hottest months are not on the equinox (June & December 21st) when we receive the most light/least light. It's a lag of about 4-8 weeks.
When parents scold their kid for being selfish, the kid needs to remind their parents that they are literally the center of the universe.
Simon. You do what you do extremely well.
I listen you when I go to sleep .. And it's nap time!!
yeah. yawn
Keep it down will ya? 😴💤
I listen you while you're sleeping. Night night!
The vast majority of stars, both in our galaxy and elsewhere, are red dwarfs. Red dwarfs are expected to last TRILLIONS of years. Though obviously with the universe at only 14-ish billion years old, we haven't yet observed any run out of gas yet!
I really enjoyed this video! And the sound from the black hole at the end of the vid was quite eerie.
And to paraphrase George Lucas, “ In space, women don’t need bras.”
Gives me a queasy feeling trying to visualize.
Only until we generate any form of fake gravity. Build a nice spinning-cylinder habitat so that stuff doesn't float around weightlessly and our bones don't decalcify, and we're back to bras again.
The earth is the center of the universe as Jupiter would be if we were there. It’s the observable universe and since we are located on Earth the observable universe is centered on us where we are viewing from. People have trouble understanding that?
So therefore, there is no real center... everything is a matter of perception to us.
Very interesting. Some of this I knew but other parts I definitely did not. Another masterterful episode in my education.
Haha! "It's extremely difficult to crash into a black hole on purpose, let alone by accident,"
"So, how was your weekend?"
Well, I had immense difficulty crashing into my favourite blackhole, and that was actually trying to crash into it intentionally!!'
"That sucks. Well, better luck for next Sunday then!"
Fun fact: The Star Wars galaxies are in the Abell cluster. That's why fighters bank like airplanes and shutting down your engines slows you down.
Star Wars richly detailed galaxy, often referred to simply as “the galaxy.” The galaxy is one of trillions of galaxies in the Star Wars observable universe. It consists of over 400 billion estimated stars and more than 3.2 billion habitable systems. These systems orbit around a supermassive black hole known as the Galactic Centre, which lies at the heart of the galaxy.
The galaxy’s structure includes four major spiral arms that rotate around the Galactic Centre. These arms are:
The Perlemian Trade Route
The Corellian Run
The Hydian Way
The Rimma Trade Route
Norma Cluster (Abell 3627): Located near the center of the Great Attractor, this rich cluster of galaxies lies about 68 megaparsecs 222 million light-years away.
Hercules Cluster (Abell 2151): Situated in the constellation Hercules, this cluster contains around 200 galaxies and is approximately 500 million light-years away.
Massive Galaxy Cluster Conglomerate (formerly Abell 3192): Originally believed to be a single cluster, this conglomerate is located in the constellation Eridanus.
The M.G.C.C is a supermassive structure, which exhibits gravitational lensing effects. The Abell cluster is a fascinating collection of approximately 4,000 galaxy clusters, each containing at least 30 members. These clusters are almost complete up to a redshift of z = 0.2. The catalog was originally compiled by the American astronomer George O. Abell in 1958 using plates from the Palomar Observatory Sky Survey (POSS). I didn't know George Lucas was an astronomer or involved in the POSS, that is interesting..
🙄
@@mrhassell Umm... It's a joke. I don't think Astronomers knew about that cluster when SW came out, much less GL. I was poking at the SW dogfights and in-universe physics, and the "A long time ago, in a galaxy far, far away..." line.
@@taitano12 Idk, from the form of the comment, maybe an AI Bot is trying to strike up a nerdy conversation with you?
Hmmm wrong channel. The universe is the ultimate in megaprojects.
I was expecting this on Astrographics
0:40 The one likely counterexample is the star Betelgeuse, in the constellation Orion, which has been undergoing a number of disturbing (at least to astronomers) distortions and brightness changes that suggest it may not be long for the universe, with some astronomers arguing for its going supernova in mere decades. This would make it the ninth supernova spotted within our galaxy, going back to SN185, recorded by Han dynasty astronomers, with the most recent being SN1604, studied by Johannes Kepler among others.
You just compared a black hole to New Jersey. Bravo!
I was at a sci-fi con where the Science guest of honor was Dr Robert L. Forward. He said that re: us appearing to be the center of the universe, because other galaxies generally appear to be moving AWAY from us (well, except Andromeda which is coming toward us). He said, "Picture a deflated balloon. Take a black magic marker and put dots all over it, then blow up the balloon. The black dots all appear to be moving away from one another! And that's what the galaxies are doing." He was so nice answering all of my questions, lol! (Sorry so long.) RIP, Dr. Forward.
BTW, IMO magnetars are far scarier than black holes. Y'all ought to Google the word, or look it up on UA-cam. They're fascinating. To give an example, a magnetar FIFTY THOUSAND LIGHT YEARS AWAY gave out a "hiccup" and it affected Earth's ionosphere. That's how bad-ass they are.
Kudos to your writers. This science stuff is not easy and they do a very good job.
U always make great videos
There is a video from Anton Petrov posted just today detailing strong evidence that the range of no escape is quite a bit larger than the event horizon.
The plunging region.
Range of no escape. Sounds like my ex 😂
The Howl of the Blackhole is beautiful.
Maybe someone smarter than me can answer a question. So the universe is expanding and accelerating eventually even faster than the speed of light. The light coming from distant galaxies starts red shifting to lower and lower energy levels eventually flat lining when the expansion reaches light speed and light can no longer travel outward. But then the expansion exceeds the speed of light, so does the light shift into a negative spectrum? If so what happens, does it then start to take on mass? Light speed is zero motion through time and maximum motion through space, allowed due to zero mass. So with zero mass faster than light speed does light start to take on mass and increase it's motion in time while decreasing it's motion through space? Maybe that's what dark matter is, just light shifted into a negative spectrum?
I don't believe light can ever redshift to the point it flat-lines or becomes negative. All that redshifting means is that the wavelength of a photon stretches. Theoretically, the wavelengths of photons can keep stretching forever, getting closer and closer to zero but never actually reaching it.
Also, photons that are too far away to ever reach us are traveling slower than ALL of the space between itself and us, but it's still traveling faster than the space between itself and other particles that are closer by. So it is only traveling slower than space relative to us, not relative to space that is close to the particle.
According to one theory of the end of the universe, "The Big Rip," space could eventually expand so quickly that even space close to a photon could begin to expand faster than the photon could travel. If this is the case, no one really knows what would happen. We don't yet have a working theory to combine general relativity (the theory that predicts/describes the expansion of the universe) and quantum mechanics (the theory that predicts/describes particles like photons), so all scientists can do right now is speculate.
Keep in mind I'm not a physicist, just an undergrad with a long-standing special interest in physics, so take this all with a grain of salt. That being said, I hope my answer can help! :)
I distinctly remember in Grade 6 (this was in the 1970's) .. Our grade 5 and 6 (combined classroom) teacher telling us the sun was FARTHER AWAY in Summer (as is the truth, IN CANADA)
But we as students argued that was not right ...and further completely disregarded the lesson and, we all got the question wrong on the test. .. the fact summer occurs in JANUARY on the other side of the world was never discussed!
Some kids even asked their parents to intercede and the parents said it was not worth it, and the teacher was just an idiot. As "everyone knows" the earth is flat .. I mean closer to the sun in Summer.
I myself walked home the day after the test (we had a school bus but it was only a 1.5 mile walk) ... and stopped at the Library in town, and looked up the fact the sun INDEED is FARTHER AWAY in summer, in an older Encyclopaedia Britannica, form the early 1950's
Better not use a black hole for a slingshot manoeuvre! I did this once - with the result of a seven years gap in my UA-cam channel's uploads, due to time passing slower near a black hole.
Speaking of the sounds in space, there's a great channel called V101 Space that profiles the different sounds of our solar system and it's awesome. Also, I find the black holes "being scary" thing kinda silly considering how many people nowadays are talking of how people want to utilize them for different things be it potential habitats, energy production, or interstellar space travel. I think the fear mostly comes from the lack of comprehension we can fathom due to how outlandish they are cosmically compared to what we deal with on our tiny, mundane blue planet.
They are terrifyingly destructive and to fall into a black hole would feel like being stretched apart until disintegration for what feels like eternity due to the time dilation that occurs nearer to the black holes centre. So not great
@@carlstanford7607 You'd have to actively try to get swallowed up by one. Also, time dilation doesn't work that way for you. It's not that you experience time more slowly, it's that it would seem that way to the observer. Eg. if we were traveling at near the speed of light, we wouldn't be moving/experiencing things 99% slower. PBS Spacetime does a great breakdown on how this would work with 1 person being swallowed up and one person at the event horizon, observing. The one falling in would appear to be "standing still" in space.
The universe never ceases to perplex and amaze me.

We are closest to the Sun during the summer, in the southern hemisphere.
THANK YOU for not implying that the observable Universe or any variation of "the Universe" is product of a single "big bang". I'm so fed up with that because it's so rare that anyone talks about the Universe without claiming that to be true. I recently saw something else that implied it so I'm starting to assume that after decades of my own fustration that media and science are finally starting to much more widely acknowledge should have been really obvious the entire time. (And certainly since 1997-ish.)
Realy I like this video so so much like you can imagine its so interestyng
Imagine living in a galaxy where you can constantly hear the black hole at the center of it. Talk about music of the spheres.
The Perseus Galaxy black hole just sounded like a wind storm to me?
So all the scientific evidence points to a universe that is expanding faster than the speed of light. I believe this is yet another reason why faster than light travel could never be allowed by the laws of physics. Because if this were possible, you could actually reach and theoretically overshoot any theoretical "edge" of the universe (if such a thing exists). For this reason alone I can't possibly see how the laws of physics would ever allow it, it would break the whole system.
Edit : It's also quite possible that FTL travel would seriously mess with time, potentially (in theory) sending occupants of an FTL vessel backwards in time, as at C time stops. No need to even get into the problems with causality and potential paradoxes this could cause. If you went backwards in time and were traveling at such speeds the universe would "deflate" from your perspective and where would you even end up? It can't be any more possible than creating a time machine out of a DeLorean 😂
I was wondering if I'd been misconceived but I already knew everything you mentioned thanks to the OG facts boy Simon Whistler! And all his great videos giving us all a better education than we got from school. I hope your empire continues to dominate.

_The lifespan of stars range from 15 million to 20 billion years..._
That's an understatement. The lightest stars may life for trillions of years. Of course, they aren't visible with the naked eye.
I was thinking the same thing, many red dwarves have estimated lifespans in the hundreds of billions to trillions of years.
How is this guy on every other channel?
Persons Galaxy cluster - yeah that “sound” isn’t enough to creep someone out..
Thanks for covering the first point. That meme just keeps circulating even though it isn't true.
Very interesting!
Be warned, existential crisis beyond this point.
Three stars circling the Milky Way’s halo formed 12 to 13 billion years ago. Care for another existential crisis, just for good measure?
It's not really an existential crisis. You're just not as special as your parents LED you to believe
This is one of the least existential crisis inducing side projects I've seen in awhile
@@fathertimegaming17 But we are each the center of the universe. That has to be the first ever participation trophy.
"Dead stars, still burn. Dead still, stars burn"
7:58 - If you want to narrow it down even further, we are each the center of the universe.
What specific evidence are you referring to when speaking about the geocentric model? Very curious about this. Thanks!
Thanks for that ending thought
RE Stars possibly being gone when we see their light, let us dream Simon, let us dream.
10:48 noooo the jazz returns
That little hell graphic at the end is(I'm pretty sure) the same one in the new @4saken song.
Black holes can devour entire galaxies becoming quasars but sure they’re harmless! Probably the craziest thing I’ve heard Simon with huge assumptions, sophistry, relativism, and conflations throughout. Black holes are the destructive engines of the universe however given the scale of space we are fortunate to not having to worry about them.
"...that amorphous blight of nethermost confusion which blasphemes and bubbles at the center of all infinity - the boundless daemon sultan Azathoth, whose name no lips dare speak aloud, and who gnaws hungrily in inconceivable, unlighted chambers beyond time and space amidst the muffled, maddening beating of vile drums and the thin monotonous whine of accursed flutes."
That ending is :chef kiss: lol.
9:58 So staying safe from this sample black hole is as easy as staying out of Jersey!
(No disrespect to Jersey.)
The biggest misconseption is that astronomers and main stream cosmologists actually know what they're talking about !
Yup sounds like an Eldritch horror alright.
2:10 Red dwarfs probably have a lifetime in the trillions of years. And most stars are red dwarfs -- granted, they aren't visible.
The universe is a side project

@@julianaylor4351 it was a joke, based on the name of the channel you are commenting on....
@@captainspaulding5963 Obviously my joke back to you was too subtle. 😁❤️
:o I gave a talk very much like this a few weeks ago at my local observatory! My preamble was basically identical 😅 and a couple of the misconceptions I addressed overlapped with these! Wait, were you there?!
Could you ask your neighbours to turn their damned music down?

Glad I'm not the only one who finds every sound NASA brings to us creepy AF!
Danger from black holes isn't just falling into it, but 1) being captured in its orbit for all eternity, 2) periodic high energy radiation bursts, 3) the Roche limit is huge and will shred any objects into atoms at hundreds of millions of kilometers away, 4) time dilation as you get close will ensure that everything you know or love is long gone before you age and die, and 5) depending which direction you orbit, with or against the black hole spin, frame dragging will slow your orbit each time around, pulling you closer and closer.
Isn't it theorized that if you are caught in the event horizon of a black hole that time will slow to a stop for you? If this is true then wouldn't it also then be impossible to reach the singularity, as if time stops for you then all movement would as well. I am sure there are other factors like being crushed by gravity or cooked by radiation, but if you somehow could shield yourself from that, would it just be a fate that completely froze you in time for eternity? That would be pretty unpleasant to say the least.
I thought your number 1 would be the Big Bang starting with a singularity. Yes, there was a Big Bang and it was a singularity, but it more and more cosmologist believe it was a singularity in time, not a physical point. The analogy I like to use is supercooled water. Many have probably experienced this. Its when you have usually relatively pure water in a glass in the freezer and it's not frozen. But as soon as you disturb it, it freezes almost instantly. The theory is that there was energy everywhere that slowly cooled over time . Then, at that singularity in time, it instantly "froze" everywhere. EVERYWHERE. The expansion of the universe (and there is debate if expansion is really happening) is not due to expansion from a "bang", as often depicted, but that all of space itself is expanding, and there are many theories as to why that is happening.
On point #1, due to relativity, you can argue that anything we observe at the speed of light is in some sense happening "now" - not "N years ago" for a star N light-years away. (Because information cannot be transmitted faster than the speed of light.)
From this point of view, the statement that "some of the stars in the sky might have burned out thousands of years ago" can be refuted by walking outside and looking up - if you can see it, it's still burning. The fact the photons were emitted 1000 light-years away from your retina is irrelevant.
(It's a bit of a simplification to use photons, but it's close enough, and it's a lot easier to observe light than something that ALWAYS travels at EXACTLY c - eg. gravitational waves.)
Judging from the sounds they make I have come to the conclusion that black holes are literal portals to hell itself.
Do you guys have a channel on folklores or myths?
We know so much until we find we know so little
Fun fact: Any work published by an agency of the United States government is in the public domain by law. So you can republish anything NASA produces (on its own, not through a contractor) without even crediting them, although you really should just so that people understand what they're looking at. Or hearing, in this case.
Misconceptions:
1) you can time order distant events, e.g. "Betelgeuse has already exploded"...we can't time order it until we see it. Fact.
2) related: the earth spins once per day (false).
3a) That the entire universe was tiny at the start, no, we only know that the visible U was.
3b) That saying "The Earth is stationary at the center of the universe and stars revolve around us once per (sidereal) day" is wrong. General Relativity disagrees.
Interesting video answered a question that I've had for ages. That is our sun will last 2.5 billion years yet we are taught everything on earth comes from stars, the universe only being 13 billion years old all seemed lucky tight timeline.
Earth is not a typical planet because basically everything about our solar system is not typical.
Which makes a habitable planet all the more of a rarity. ❤️

_...well beyond what we can see,
most likely to infinity._
You're a poet!
"mostly harmless"
haha I see you.
at 7:26, the Earth is rotating the wrong way.
All hail, Father Simon!
Here's some TidBits:
- The Earth Does Not Orbit the Sun. Both the Sun and the Earth Orbit the Solar Systems' Common Gravitational Center...which is very close to the middle of the Sun.
- Daytime gets longer in the Winter and Shorter in the Summer. The longest day of the year is June 21st. This is also the First Day of Summer. So as soon as Summer starts the Daytime will begin to Shorten. The Opposite happens on the First day of Winter, December 21st.
- The Earth's North Magnetic Pole is in the Southern Hemisphere. A Compass has a tiny Magnet which has the North Pole of the Magnet painted to mark where it Points. The Magnets North Pole points Directly towards the Geographic North Pole above Canada. However, with Magnets Opposites Attract. This means the North Pole of the Compass Magnet is Attracted to the Earth's' South Magnetic Pole. And the Magnetic Flux of the Earths Magnetic Field Comes out of the Earth in the Southern Hemisphere and reenters the Earth in the North Pole above Canada. This Flow Direction of the Magnetic Flux causes Solar Storm Particles (CME) to be Trapped in the North of the Earth. And, we get Awesome Northern Lights here in Canada Because of it.
"Daytime gets longer in the Winter and Shorter in the Summer. The longest day of the year is June 21st. This is also the First Day of Summer. So as soon as Summer starts the Daytime will begin to Shorten. The Opposite happens on the First day of Winter, December 21st."
How sure you're about that?
Let's say that you're in middle of a summer in Sydney or anywhere else on the southern hemisphere. What do you expect to see?
@@XtreeM_FaiLEverything is just the opposite in the Southern hemisphere. I'm sure the OP is referring to what happens in the northern hemisphere and is probably where they live.
Think of us being a tiny object, on a table, in a room, in a house, on a planet, in a solar system, in a galaxy, in a universe..... 🤯😎😁
The fascinating thing about the universe are the paradoxes it presents. It's 13.5 or so billion years old yet 93 billion light years in diameter, among the countless other weirdness our theories and discoveries have highlighted. Cheers....
The acceleration of the universe's expansion is a likely explanation for the 13.5b vs 93b disparity. So that really isn't a paradox.
We’re in space, therefore there is sound in space.
Checkmate, scientists.
