Hi Alex, If electrcomagnetic radiation is the most pure elemental form of energy in the universe and all matter can be converted into this form of energy by imparting enough energy into it, wouldn't it stand to reason that everything that falls into a black hole inevitably becomes electromagnetic radiation? Therefore the inside of a blackhole would be nothing but light.
If you consider that a photon doesn't experience time or space implying that from the photon's perspective it arrives at it's destination the instant it departs it's source or travels no distance in no time. To me this means that the inside of a black hole has virtually no size or space, just a Planc length single photon with an energy approaching infinity.
Or is there a point at which even light breaks down?
I always thought stars in a galaxy spin around a super massive black hole due to the extremely high mass of such black hole (just like planets spin around a star) until I found out, that the percentage of the mass of a black hole is VERY small (m
could you talk about radiotelescopes ?
Thanks just signed up...
The mass of SMBHs in incomprehensible to me. Given the great distances between stars, even the ones in dense regions, surely a billion stars couldn't all coalesce in one place? Was it just a bunch of gas that would have become a billion stars, and fed the SMBH instead?
I don’t know about black holes being the most dense objects, I met this one person that was so dense not even logic could escape.
I laughed way too hard at this 😂
@@emmanueludi-ken9382 I think I met his cousin in a bar once. I heard a very good bit of advice once. I forget who said it tho... "Never argue with an idiot lest you become one too, for arguing with an idiot." I never forgot those words.
@@billd.iniowa2263 "never argue with a fool. He will take you down to his level and beat you with experience" 😂
I’ve been working on it, but my density levels skyrocket when a woman is trying to flirt with me
They could have been a logic white hole, of high _negative_ density, so that they repelled logic.
This guy sounds like he's smiling whilst talking
I know I would.
Sounds like he about to laugh
How could he not? You can tell he absolutely loves all things outer space.
You nailed it on the head. Spot on.
Every new video this comment appears haha
I’ve immersed myself so much into all things astronomy lately that the more I learn the more it’s starting to feel as though we live in a fictitious universe. Things are so ridiculous it’s as though it’s being conjured up by some grandma telling a bedtime story.
I really understand where you're coming from, this has been blowing my mind for the past 10 years. It's an insane reality, the vastness of the universe, the way things work on a cosmic scale and quantum scales... It's mind blowing. And I don't mean mind blowing in a normal "woah dude, you blew my mind" kind of way... I mean it in a way that is altering my whole mental make up, the way I think about everything and live my life in general. Whatever this is, this world, this universe, this reality... It's very very strange. Not enough people realize this, most don't even think about it. We're on a giant rock that created its own life over the course of millions of years and somehow we have come to the point of self actualization and consciousness... All while being hurdled through an ever expanding universe at 100's of thousands of mph's. At the same time there are nearly infinite, GARGANTUANLY ENORMOUS events happening all around us (on a cosmic scale), stars exploding, neutron stars merging, supernovae exploding, GIANT SCARY ASS THINGS (blackholes) eating everything in its path and we literally know almost nothing about these things. Black holes are insane to think about... I have a feeling they aren't what we think they are. Not saying they are some kind of mystical thing, but I think the universe still holds many secrets and that reality is much much much stranger than we think.
This life literally doesn't feel real at times. Look around you and try to think about the things we see day to day and the people around you. We are literally sacks of meat with this thing on the top of our body that has all of these mechanisms so we can evaluate and respond to our surroundings. The human face is so strange if you think about as if you were seeing it for the first time. We are these things that do things to get more things and then we ultimately lose everything and no one knows what happens once we're gone. We're this little buzzing beehive in a universe so vast its incomprehensible. Just a lone little dot, a speck of sand secluded in our own little pocket of the universe. It's terrifying, invigorating, and absolutely insane if you think about it deeply enough.
@@GuitarDiddlerJP15 Richard Feynman - "To every man is given the key to the gates of heaven. The same key opens the gates of hell. And so it is with science."
@@GuitarDiddlerJP15 I love the excitement that oozes through your writing. I share your feelings of astonishment at the profound strangeness of the predicament we find ourselves in. Reality is absolutely insane and the fact that there is anything at all already breaks my brain. How some people can waddle through life never questioning it all, is beyond me. The Universe definitely still has many strange, paradigm shifting surprises to show us. I'm so grateful to be alive and conscious, capable of experiencing even a tiny slice of the magnificence of being.
@@karltanner3953 it's nice to know there are people that think in a similar way about these things! I don't know many, if any people in person that share my level of interest about them. It's sad! All I want to do is talk about this stuff every day and I'm very limited on who I can converse with because I start to lose their interest. It's quite an amazing life and I can't wait to see what the future holds. The James webb telescope is the next step for our civilization! I'm so excited to see what comes from this experiment!
"Why Aren't There Quasars Close to Us?" Another reason might be that if we were anywhere near one, life couldn't exist on this planet.
This was the thought that immediately came to my mind.
Was about to say, because we are here...
That seems an unlikely outcome, seeing as how "close to us" in this context simply means finding one in a nearby _galaxy._ Even a quasar in the Andromeda Galaxy wouldn't wipe out or prevent life on Earth unless by really unlucky chance its polar jets happened to be pointed exactly this way.
@@scotte4765 Sure about that?
thats not a reason that THEY arent near us.

Astrum deserves millions of subscribers. This content is solid.
Very cool. Sometimes when you have a surprising result from data, you need to rethink how you're interpreting your data. Accounting for differences in how it was collected or where it's from can make all the difference.
Thank you for this excellent video!
Amazing! Been watching your channel for almost it whole existence. Deffenitly one of my favorites. Sparked tons of curiosity of how scientists can even know so much. Thanks for all the good content!
Dude, this was an INCREDIBLE video! Thank you so much!
If someone from those distant galaxies looks our direction now, do they perhaps see a quasar that existed long ago where we are?
There my be a QSO here once again when the MIlky Way Galaxy merges with Amdromeda, but no human will be left to see it. :(
@@photonjones5908 humans could be alive at that point if we’re advanced enough
@@frostyvr9805 Well never say never but I am pretty certain that anything we would consider to be human will be long, long gone. You are talking about an interval of tiime greater than the entire existance of living things on Earth, including room for at least five mass-extinctions events. Human advancement as we think of it is probably not sustainable anyway, The real question is, will there be ANY life on this planet in another 3-4 billion years, I think ithat is possible, that is, if any life survives US. The winds of change prevail.

Very informative video! Black holes are so cool
wonderful video, thanks for sharing learned so much
I’ve always been curious about space, thank you so much for uploading these videos!!
Yeah. I like to say, space is really cool until it gets really hot
I love your videos! Thanks for making them!
Thanks for the subtitles!
The music choice is on point as always!
Hey, I remember you made a community post about how we felt about you changing titles/thumbnails, and I have a solution. You should just include a section in the description of the original title so we can search them by memory
Love these vids in 4K! Looks amazing on a 55" 4K TV.
I cant stop loving your videos
that was the smoothest transition to a sponsorship i have ever seen
ikr like I didn't even know I was watching a sponsorship until the code
I wouldn't know because I use SponsorBlock lol
Yeah that was creepy right ?!
This is one of the few channels where you can preemptively like a video. Always great content. 👍
Great video! I'm fascinated by Quasars!
Me after reading title:
Hmm, I wonder why.
Video: "Black holes-"
Me: I heard everything that I needed to hear.
WOO HOO! Astrum is back!
Great video as always! When are the rest of the Apollo episodes coming?
Every time I watch something like this, it fills me with existential terror. Lovecraft wrote of people going mad from understanding the true nature of the universe. Trying to imagine a black hole with mass on a galactic scale, or trying to really appreciate how far away it is...
It unsettles me. I just can't easily cope with it.
There are a lot of pieces of information that have made me quake.
Knowing that space has no end, we are but a speck smaller than sand in the greater picture...
Knowing an asteroid could again cause an extinction event and we have no way to stop it...
Knowing in a billion years or so, our own sun will be too hot for life on this planet...
Knowing that with the right microscope, as you zoom in smaller and smaller, it starts to look like a universe...and maybe our galaxy is just a dust mote on someone's floor.
All this type of thinking makes it hard to go to work, pay bills or care about 'the economy'. It's so made up.
Don't watch these videos then
I've never understood the perspective that astronomical concepts are frightening to so many people. One of my favorite things about astronomy is how soothing and un-frightening everything about it actually is because it's so far removed from our everyday life that it's unlikely to ever affect us.
@@ewqdsacxz765 It's just the sheer immensity of scale. The idea of a black hole bigger than the solar system is just insane toe. And distances grow so large so fast that numbers are almost meaningless. Sure, we can do the math and get accurate distances, but even truly appreciating the distance to the sun is difficult forost people. Let alone distant galaxies.
Excellent as usual !
It could be that a fundamental mistake persists in our calculation of mass and distance, despite consistencies, such that objects far far away are estimated to have an exaggerated distance and exaggerated mass.
This is my assumption as well.
I love these videos so much I wish I could have a new one every night
Because they haven't had the time to reflect on themselves.
aha aha ahahaha
Thanks for your great video’s! I do think the background music was kinda distracting (starting at 4:14). Never noticed that with your other vids. Anyway, keep up your great work!
It's funny, for me it had the opposite effect. It really helped me to submerge
It's amazing how often space channels keep describing the basics of blackholes
Favorite channel no cap
Great video. I wasn't aware of this.
Love your videos
Had 2 pause this twice coz I thought a car alarm was going off outside my house. I then realised that it wasnt. Which was pleasing. And finally I realised that it must have been on Astrums end when recording. And finally I'm left hoping it wasn't his car alarm. What an emotional rollercoaster that was.....
Great explaintion
Our universe = yep, I knew it'd be a great place to stay for awhile!
The animation at 6:50 was gnarly 🤘🏻
perfect timing for a drop
I think you need to clarify we see more from further away. One reason is that we only see a quasar if we are within its emission cone and as we all know the cross section of a cone gets bigger the further you are from its apex. That means that it is really good we don't see any nearby quasars. Being in the cone of a nearby quasar would vaporize the surface of out plant and everything on it.
so it's like anthropic principle? they are not in our neighborhood, because if they were, we would be fucked up and we couldn't exist to observe.
Very interesting. Thanks.
I knew the universe was smaller and had more gases but yeah, this makes sense once it's explained.
It can be older than 2.8 billion years old as the universe is also expanding. So while it may take 10 billion years to reach us, some of that delay will be caused by the constant expansion of the universe. Great video as always!
Has it ever been theorized that black holes really aren’t black holes but that they have just reached a point where light cannot escape and that we really cannot study them to grasp what they are?
Nope
They are the universe's way of being nostalgic for the simpler times.
But seriously, going by the math, black holes are some of the brightest things in the universe, but only after you go past the Schwarzchild Radius, and I don't recommend that.
Dude, the black hole thumb nail was the best one in my option. Anyways, keep up the great work.
Imagine being in the Galaxy where ton 618 resides and no matter what planet you are on, you all see the giant bright ass black hole illuminating everything..
Quasars and Blazars are some of the coolest things in the universe!
Is there any atomic nuclei fusion on quasars' accretion disks? If so, what kind of elements would be formed there?
I give this video a 10/10. I smaaashed that like button.
You have done well
Your videos should be on CuriosityStream.
Sometimes when I stargaze and contemplate the universe, I feel a sense of dangling out, hanging from my feet peering into the vastness of space all around me.
climb up into a tree
it's bloody great 🙂
It's the chicken and egg problem which came first: Galaxies or black holes. Probably black holes because the supermassive black holes attracted all that material around it which is orbiting the black hole at a superfast velocity to the point where all that mass is flattened out into a galactic disc.
I also like to ask a question, "do you want a quasar next to your planet?"
damn. he changed the title.
Even better, would our solar system survive in our section of our galaxy if our galaxy was a Quasar?
Go watch what if
@@SomeRandom6uy Yep. a practise of inconsistency.
Thanks for helping me fall asleep
So, I had a strange question.
Would Hawking Radation be in effect at the very moment of the black hole's creation?
If we calculate the dissapation of the black hole from the time of creation, would that explain why the older quasars are now smaller? they have shrunk even though they are consuming and still gaining mass?
Yes, hawking radiation is in effect always, as long as the universe's rules don't change.
No, hawking radiation takes *much* more longer than the current age of the universe to dissipate, at least for large enough objects.
Say, the mass of our sun and larger
Awesome 👍
Great 😍
"You are looking at galaxies that are billions of years old.."
"But even the Event Horizon Telescope takes AGES to image a black hole."
It took a few hours 🤣
Question
Do supermasive black holes at the center of galxies evaporate faster overtime ? Bilions of years instead of trilions
I am asking beacause black holes in the farthest galaxies seem more massive than those closer.
The age of quasar may be coming to an end, though when Andromeda collides in 4-5 billion years, the galaxy may shine bright, one last time.
I love this area of TH-cam!

Awesome video as always! Im also making videos about space and astronomy!
6:29 universe becomes more chaotic the more it spreads out.
what i find interesting is that they say (nothing is faster then light and loght cant escape black holes) yet thoretical everything needs a certain velocity to escape gravity of planets and orbits. but still they also say that some black holes spew out material in a super jet. so how can material escape, when nothing can go faster then light . somehow it must be faster to escape the gravity of the hole or it would just get sucked back in as it spewa out.
How come I never hear scientist acknowledge that when we see other planetary systems in other galaxies, that these were images in the distant past? If our planets have moved around different distances through out time, wouldn't it also make sense that those we see in other worlds, planets that were not in a goldilock zone, may have moved as well? I have not heard this talked about.
If you ever see videos from the Hubble TH-cam channel, they often talk about how far in the past these stars and planets are. Redshifting is a good way to understand just how far away something actually is.
The most distant exoplanet discovered is SWEEPS-11 at 27,710ly away. There is a possible detection from the Andromeda galaxy, but otherwise every exoplanet we know of is basically in our cosmic backyard.
Because the planets we’re currently seeing are all (relatively) close to us. And they’re all located within the Milky Way.
Just wait til they launch the James Webb Space Telescope… it’s happening! They’re launching in December. It’s so powerful that we’re actually going to be able to see these exoplanets in detail! It’s an exciting time to be alive!
Amazing video..!! Thank You Astrum for share..!! I have a question, if you kindly response. What is the difference between a Quasar and a Black Hole ?-
A black hole emits no light, while quasars can emit light a trillion times brighter than that of our Sun.
@@1878reddevil Thank You..!!
Don't worry,
the Age of Man will come to an end long before the Age of Quasars enters its final moments.
OwO
HERESY!!!!
When will the Age of Orcs begin?
Makes sense and adds a whole new aspect to it all, thanks
I love science and one of my favourite things is the question of how old things are. What if we were wrong? What if we are less than 1b years old? What if we have mistaken something with the speed of light? I love the idea that we dont actually know. Shows us how much more and how much further we have to go to even begin to try to understand the universe.
I'm allowed to ask this question because all we "know" is based upon theories and while they are logical theories... they are theories based on their predecessors theories based on their predecessors theories and thus the world could be the nerdiest game of Chinese whispers ever.
It's fun to speculate and as I said, I love science and I love the questions that dare question the reality we know.
Also to be clear on the speed of light:
We make lasers, LEDs, we measure and use ionising radiation like X-rays, we use microwaves for communicating over large distances, we measure spectrography of distant objects or to identify the elements in a substance, we observe distant objects or measure light using cameras and light sensitive diodes. We measure and observe the release of energy from electrons as they get excited, we see energetic events give out light in a measurable and predictable way. We can see with our eyes, plants photosynthesize.
All of this works and works together in a unified, consistent way because of the relationship between the wavelength, frequency and speed of light. If we're wrong about that, none of this stuff works. No lasers, no observations as we see them, no ionising radiation, no spectrographs, no red-shift, no cameras.
I hope you can appreciate that things like this are so fundamental and distributed throughout all of science and known so clearly and thoroughly through many disciplines that really you can't treat it as if it's some isolate bit of mental logic that someone's passed down or it's some special case that we might be wrong about. If that one thing is wrong, nothing works. Our understanding of light and its properties is based on experimentation and observations rather than a speculative idea. The stuff I listed above works *because* light has those properties.
The way you described science above, is sort of how we'd describe religion or philosophy. Like you notice a specific thing about the world and speculate about it in isolation, a 'special case' way of building your ideas. Science works the opposite way. If an observation is made in science and said to reveal something about the way the universe works, it also has to match up with every single other observation and theory across every discipline and be proven via experimentation. As soon as you find a case in which it doesn't work, that's it. It's chucked out. This is how we know we're right about some things and others are still up for grabs.
@@purklefluff the framework is built on theories, new theories must fit in the built framework, what if our framework is only a small part of a bigger one? we won't know, we assume what we see or measure is true, but is that all that there is to it? will the framework bend if certain conditions are met? have we missed fundamentals that would change how we view things? yes, we found properties of "light" and can built technology around these but this is just a facet of it. Theories that built the framework can be overthrown, if so everything that is built upon them as well, sometimes we took shortcuts and just included it because it worked while it may not fit in the framework after further discoveries or we were to bent on being "right"
@@Sharlidar scientific method takes care of it, if there is something wrong with a theory the community will take care of it itself. Science is a self correcting body, after all these theories are different from the usual ones, they are tested, and revised every now and then, their derivation are taught in schools which increases the chances of finding an error if a student or a teacher ever notices something. It may look that fragile to an outsider but its rightfully not, and if it was its still not a thing to care about because most of the error will be very small, the fact that we are using a device to communicate already ressures that scientist aren’t as delusion as we might suspect and our methods work ,things would still work just the explanation will be ever so slightly different.
Exciting time
Do you like reading science fiction novels? If you do I suggest picking up a book called The three body problem by Cixin Liu. Without spoilers it's about an alien race that can warp our perception of reality and all we understand about physics. 😉👍
Hey can you make a video on how large our universe is i tried reaserching about it but all of it says about the "observable universe" but thats what we can observe what is the actually size? do we even know about it?
Hooray!
I was wondering where parts 4 and 5 in this playlist came from, given that parts 1-3 were made after this video
The big bang is only an horizon on an infinite curve from our perspective... It's pretty straight forward! ;P
Question: A some point during a stars collapse won't the mass of the event horizon exceed that of the mass remaining inside the star thereby pulling it to the event horizon?
No, the event that creates the singularity catapults rapidly fusing heavy matter away from the core in a shockwave that blows the entire star apart in the same way it does for neutron stars and white dwarfs, effectively robbing the new singularity of the ability to feed on most of the star it came from
When we watch these videos, we feel that our earth is not even a dot in the universe ;but when we return to our earth , we get bewildered by the vastness of Mother Earth !
All things to scale. When presented with the sheer immensity of the universe, that can really be an ego-shattering moment.
Considering how little we have actually property measured gravity in the far greater amount of time we have theorized gravity isn't instantaneous.
It would explain why black holes that are much farther away could be so massive. You are detecting it's active forces in the present.
I realize the implications so forgive me if I'm missing a vital piece of information. From what I could gather we have never tested if gravity is instantaneous or restricted like light. The gravitational waves from recent high mass mergers didn't specify a second observation post that could perform such a task.
James Maxwell (brilliant guy) back in the 1860's calculated gravity's speed: It's moving at the speed of light.
And we have done that experiment with the LIGO arrays. One of the arrays is in Washington and the other is in Louisiana. The gravity waves observed from two merging black holes hit those arrays at different times, and the waves were moving as fast as light.
0:18 3:41 How come were always told nothing can escape a blackhole, not even light, and yet we often see these streams coming out of them?
You need to read Stephen Hawking's book, A BRIEF HISTORY OF TIME. He explains that very clearly.
What we're seeing is the black hole's magnetic fields violently stirring the surrounding gas around the poles of the black hole. If there is no gas remaining, or if the black hole isn't spinning fast enough to generate strong magnetic fields, we don't see those jets.
Another way to think of this is that this is sort of a black hole's "Northern and Southern Lights".
When a black hole fills up this is what happens
This is genuinely interesting but I actually fell asleep twice while watching this 😭😭
Your video title had me worried for a moment...I thought that all the quasars were going to be turned off next week like the old Iridium satellites!
Tiny nitpick, black holes are not necessarily the densest objects we know. In fact the more massive the black hole, the less dense it is. The largest black holes are less dense than air
I have a question. Is it possible that primordial black holes were formed in patches that had more material in it when the Higgs field established itself. Would this make space seem more smooth and spread out since all that was left was material that wasn't made into a black hole and then as expansion continued it just spread out?
Theoretical question: Ok, so in theory, the time frame near the surface of a black hole is moving much slower than ours on earth, due to a massive difference in gravity. Massive gravity = massive time dilation. But doesn't that mean that a black hole is "living" very slowly in relation to us? (really in relation to anything not another black hole). Whatever is happening in/on a black hole, it should be near infinitely slower, including aging.
To us, from our perspective living in a 1g time frame, our sun will live for maybe 14 billion years total, but in that 14 billion of our years, a black hole should only "age" a fraction of that. Shouldn't they outlive everything else in the universe? If you could look from earth at somebody standing on a black hole, they would seem to be motionless as their time dilation is severely slowed, and if they would look at us on earth, we would moving in fast forward. A black hole (or observers on one) should in theory see the entire universe live and die in mere seconds, save for other black holes with massive time dilation.
Why do we never see anybody discussing this stuff, include the idea of time dilation of black holes as it relates to it's "age" ?
While your question kinda has me shook. I believe the way black holes are aged is in regards to how we perceive time from earth. Regardless of how much time is passing, has passed or will pass in a black hole and how it is perceived to pass... time from our perspective on earth will be the same.
It's not a perfect measure, it's the only measure that best suits our understanding at this time
It's a cruel cosmic joke that I was given this ABSOLUTE fascination of the universe, but will never get a chance at seeing the incredible objects out there. When I see pictures of far off galaxies, I don't feel amazement, instead I feel a deep pain inside of me. 😢
This is going to sound insane, but all the recent discoveries in our universe is probably the only thing keeping me alive today.
I’m glad you’re alive. Hang in there
You and me both, bud. Take care.
very good
This is the strangest cover of a Muse song ever.
"Black Holes are the densest objects in the universe." Pretty sure that title belongs to Harem protagonists.
Yeah but like, we dont know what that is because we have a life

I never know what I’m looking at with pictures of these huge elliptical galaxies.
It just looks like a headlight through fog.
Where does the Galaxy start or end, and what’s just glare?
It makes it hard to get a sense of scale, even when you see them on images comparing Galaxy size.
Looks like IC1101, which spans 6 million light years in diameter
@@JCBucketDude Um.
“I can’t tell what I’m looking at” is sort of a colloquialism in English.
It doesn’t mean “I cannot identify this specific thing”.
It’s more, “I can’t make sense of this”.
One might say it when staring blankly at a set of complicated instructions for putting something together, say, or at some messy, indistinct mass.
In other words, I was *not* saying that I couldn’t tell which Galaxy was pictured.
@@joearnold6881 good for you 😄
@@JCBucketDude sorry. I thought maybe you didn’t understand what I meant, since you answered a question I wasn’t asking.
Lots of people speak English as a second language :)
If, when looking at the universe, we are seeing into the past, then is it possible to know the actual position of those observed objects right at this moment?
i hate how most of the world thinks about space as a side hobby when it’s really our reality and matter infinitely more then what we worry about on earth. i wonder where we’d be by now if everyone was passionate abt the universe
I am sure we will learn more as the technology advances as the years go by
One of my favorite days of the week is when I get a notification that Astrum just gave us a new video! 👍🏻💯 Wished there was 1 everyday!! 🤞🏻🌎🌞🌚🌝✨🪐🌙
If the largest of the supermassive blackholes are also the farthest. And what we see of them is actually what they were billions of years old.
Then could they be very very dim and less harmful now in the real time? Also is there a way possible to know the current nature of very distant objects of the universe?
thanks, yeah..
i was just wondering what are they doing now?? 🙂
This video gave me existential dread lol.
