Kurz does mention in the first 3 seconds that these stars might have existed so it's probably safe to say this video is only talking about if they did exist what they might have acted like and not implying that they were real.
No shit.
He saw that at 3:20.
To be clear I love the DJ videos, getting a little extra information is amazing. I just think sometimes things are called out for implying an idea is a known fact when it's more of an assumption that is being taken as fact to discuss the topic.
Sorry if that came off as rude. I'm just a casual nerd with maybe not the best social skills.
@@ryanbruhn554 nope, you are right, kurzgesagt made an entire fricking video stating that their videos should be taken with a grain of salt, can be theoretical and are heavily compressed because the topics are just too complex for explaining in one video
my favourite part of this video is how it shows how much is left to be discovered out in space. We've made a lot of theories that are backed by the math, but it will be exciting for us and our descendants to prove or disprove these theories. Science still has a long way to go to understand even an inkling of the vast immensity that is our universe. Things are clearly not gonna get boring for scientists in the future.
Agreed.
not descendants, but ascendants...😉🙂
literally everytime Kurgz says "maybe" and "possibly" and "if they exist" you always try to correct him with "to be clear, this is theoretical and he acts like they exist but we just dont know" .....
kurgs states literally in every video that these arent absolutely true, he makes that explicitly clear, so its funny to me that you correct him every video on something he already states
^random ass youtube user beefing with a guy wanting to show his professional knowledge and research volume 12
@@impazie im not beefing with Dylan, only pointing out that he keeps claiming kurgz isnt clarifying that these things are only theories and not true when kurgs literally says that every single video and dylan just seems to skip over it
Ikr it's so funny. But you have to think that many people might no catch that and still think that it's real. So just for better clarification I appreciate him doing it lol
@@Kidwaizer i dont mind if hes just adding more clarification but he always claims that kurgs is acting like these are facts and isnt actually letting people know its just a theory and may be wrong, when kurgs explicitly says that every video and dylan just keeps missing it
@@XiaoYueMao You have to realize that people in a few states will take his videos as fact, not understand what those words mean, and take his word as gospel. I heard him state maybe, possibly, etc..., and I thought it was a decent 'theory', but also, the secondary clarification was nice as well, just in case I missed something as well.
So cool to imagine a star so powerful it can survive the blast of a supernova AND the force of a black hole... from the inside.
to angy to die
I noticed in the chat that someone pointed out that the soundtrack in the Black Hole Star video is similar to the soundtrack in the Largest Black Hole video.
That's because they used the same OST, remixing some of the parts to fit the visuals of the video better.
I can't really blame them for reusing the theme, since that theme is the best Kurzgesagt OST in my honest opinion.
maybe it’s just for run time, but i’d like to hear the tangents that you cut out. this is all very intriguing to me, and i just enjoy listening to someone know what they’re talking about
From what I've seen on his streams, he pauses a lot not just to talk but look up stuff to show or prove something to us, sometimes he just gets distracted and starts watching something else, most times still related to the original video tho ^^
imagine if it turns out just like Agario. There was just more, easily accessible and bigger stuff around to eat back then and it was all within a small radius so they ate more of the time than they looked for stuff to eat so got big faster and there were no special "cells"
I found they actually reused the same soundtrack they used from their “largest blackhole” video in this one.
The theme song just amplified that one video alot better.
Yup, that theme is fire, those 2 guys at epic mountain did an amazing job, i listen to it every day XD
Exactly, it's such a great theme
There are a few places where currently understood physics start to fall apart - the early universe and the event horizon of a black hole. I'm not saying either break the laws of physics, just that they are some of the biggest examples of how our understanding of physics is incomplete. A video that incorporates two of these places where our understanding is incomplete is a real head-scratcher.
8:48 Who's to say there aren't faces on stars? We wouldn't be able to see them you know. Can't look straight at them and never know what direction they're looking.
Again, he doesn't say it's true, he says it may have been. It's just theory. In the other hand so many physics talk about big bang like it happened for sure, although it's also just a theory. Fascinating!
Its always annoying when people say "they may not have existed its just a theory" and then the video progresses and the person in the video says exactly that.
@@Skyte100 Whats even worse is, when the video ALREADY said that it "may have been". And THEN comes the tagent about "its all theoretical" :D
The passion you show when talking about this stuff is awesome! :)
Every super cool video I see you break the magic by saying: “let’s remember this is theoretical”
That's the reality
"No more super saiyan references, I'm starting to sound too much like a geek"
-Physics guy who makes videos talking about physics.
I never thought I'd hear someone call kurzgesagt "kurzgedaddy"
the kurzgedaddy had me from the start periodtt sassy physics guy
I'm never going to forget, "Black holes are just like pandas."
The theme is from Epic mountain studios
Their theme for this needs to be put to a movie trailer.
Stop interjecting to correct so often! They've clarified enough that quasi-stars are hypothetical.
Could you tell us about some of those more boring possible explanations for supermassive blackholes?
Oh he meant that when they actually do find out the reason for supermassive black holes in future that the reason will probably be more boring than quasi stars. But one was briefly explained where the early universe was more tightly packed together so black holes were closer to each other and merging with each other quicker.
Imagine the radiation pressure needed to hold up a 10 million solar mass star 😮
i watched the blackholestar vid less thenhour after it came out and then went to see ur reaction to before u made it.. 😂 got too excited that i forgot u cant react to it the moment the vid comes out.. lmao
Ngl I've seen your channel recommended to me before (probably because I watch others like Astrum and Dr Becky) and I'm kinda mad it took me so long to check it out. Love your vibes and the obvious passion you have for your own research and the general fields of astronomical science overall
“Black Hole Sun” Soundgarden
Never in a million billion years would I ever have compared a black hole to a panda. Bravo, good sir!
Very obnoxious commentary, constantly pointing out "it's theoretical!" in between the explanation because you "feel" like it's not being said properly. It's when someone makes an assumption too quickly before taking in the full amount on information provided. It might've been better to pause and go over more information in greater intervals instead of pausing mid explanation to tell us useless points. The random sudden transition to advertisement mid explanation as well immediately disconnected me from the video. Breaking people out of focus for badly placed advertisements is silly. The sheer narcissism of being a "physicist" and acting like the creators of the video you're commentating on doesn't know what they're talking about is very silly. They constantly point out the difference between theoretical and proven, however almost everything presented in their videos are largely theoretical which they persistently point out, they also include the exploration of other possible theories related to the topic or question at hand.
I also noticed the constant head nods as though you're a judge checking on every single word or sentence said, their extreme analytical persona presented would be perfectly fine if you were extremely knowledgeable on the subject. The problem is that it comes off as extremely bad for anyone, and for a physicist, you may not know everything said or pointed out in the video better than the analytical team that spent months to get every sentence and fact right in their video. This is the narcissism of those who throw around their qualifications as though they're an authority of truth and act like it in their voice, posture and mannerisms.
🤣 You understand you're on RUclips right?
@@DylanJDance You're not used to seeing a passionate take on a video? Is it because everyone uses a platform one way, therefore I should abide by social contract? Are you just trying to ratio me without considering the criticism?
Mate, if you had the time to respond, you also had the time to read something just over 200 words.
I saw the video when it was released and was really interested in these dark matter halo's. I haven't heard of those.
In 3:20 Kurgz says "if they existed" and you say "now its better", but since the start of the video Kurgz said "may existed".
You constantly try to "correct" Kurgz, but they always set clear that is all theoritical.
Thats not cool man.
Quasi stars make a lot of sense to me, at least as a contributing explanation for the relatively flat geometry of spiral galaxies, with exception to elliptical galaxies which I are believed to be formed by galactic collisions/mergers. Further, wouldn't the object left behind after a Quasi-star has died be a Quasar?
This is speculation, as I’m not a physicist, but here’s what I understand:
The biggest ones probably still have loads of gases from their discs, allowing quasars to form; but the majority would slowly lose theirs as large sections get thrown away by other objects coming nearby, slowly consumed until there’s nothing left, or just not having enough to form a particularly long-lasting or powerful accretion disc to begin with. Quasars need really big black holes, so some Quasi-Stars wouldn’t be big enough to birth a quasar on their own. It’ll instead be accreting, spewing out gas lobes for a while, then die down because it had consumed all that’s there and become practically invisible. Enough Quasi-Stars merge together, though, and you might get Ultramassive black holes at the heart of quasars. Many will become Supermassive instead, like our home galaxy’s Sagittarius A*. It’s worth noting the positions of these at the heart of dark matter halos makes them already central in galaxies and galaxy-forming bodies, helping reinforce our theories of Supermassive and Ultramassive block holes at the centres of most galaxies.
20:12 "This theme could be in a movie..." you mean like Interstellar? The movie whose music it is clearly referencing?
16:00 why doesnt it make sense, Ive never seen people just assuming, that there were already giant black holes formed with the big bang. i dont see it being impossible, that with the big bang or in the first moments after it, already giant super massive black holes formed, and these then later were the seeds for galaxies to form around.
It's not nonsense, this is a possible solution or piece of the puzzle. These would be called primordial black holes.
I look at space like I do the ocean it's scary but also beautiful
2:09 "This is directly my shit." I hope he says that at his hooding ceremony hahaha.
To say that you know is a strong word
I have a few questions about quasi stars. If they did exist would fusion happen in the other layers. Second is what colour would the star be? Blue? or a wavelength we can't see
Was confused about the "no anime discussion" edit. Had it a few minutes too early!
"music in the background is the next level", ironic that it's the same music used in a video about Black Hole's size comparison)
If these stars formed, I suspect they would have been the main type of star. An entire galaxy of these? Seems pretty easy to get supermassive super quick.
Just got Qal... You're awesome and I Love your work!
"How this all happened so quickly, we don't know"...maybe it was like gears where the strongest one is the smallest and the highest ones (closer to our own time) and more spread out but weaker?
Hey dylan im curious what you think of my hypothesis of dark matter.
Basically i think the effect of dark matter is actually caused by the stars and other matter rubbing spacetime so much at really high velocities that the matter begins to warp spacetime in the same way a piece of paper wrinkles up when you scribble on it really fast.
And because spacetime develops these bumps and dips time distorts the matter which passes through these regions of space time and affects the mass of the matter within. It is the reverse idea of gravitational time dilation. I call it temporal mass dilation.
The main problem i see with this theory is the bumps which supposedly decrease the mass of matter. If this idea is correct then the mass should more or less even out across the board anyway. The way i might explain the abundance of excess mass would be that because the black hole at the center is so massive it attempts to keep spacetime taught and cuts off the peaks of the wrinkles while the troughs remain ever entrenched in the gravitational well.
An entirely other hypothesis is the idea stars and other objects orbiting the black hole have the potential to sort of carve out gravitational grooves in spacetime.
Either of these would also explain why dwarf galaxies collide and cause the matter to leave behind its dark matter. Its because that matter had been ripped away from that region of space.
Kurzgadaddy is crazy 😂😂😂
"Black holes are giant pandas" - Dylan J. Dance
Is there a universal equivalent of water going straight into a sink on the equator. What I'm trying to say is, is there equator for the universe. Like their is a equator for the earth.
Nice video also I'm glad someone mentions how godly the music is
Okay ...... Black holes are pandas ..... I tried that and got so many kicks that you cannot even imagine 😂
Very nice video!
Could you also react to strange stars pls? This video was super intersting but also confusing. 😅
When you said it was theoretical I am just here going: HES GONNA SAY IT WAIT A BIT YOU IMPAITIENT HUMAN BEING! No offense lol its just that he was literally gonna say it 10 seconds later.
Einstein himself was skeptical of black hole existence, despite his field equations predicted them. That is a scientific theory, not only explain things, but has predictions. Remember, anyone that says "I am certain of X!" , doesn't do science, walks on ego.
Surprised he didn't rip them a new one for "these scenarios that will never exist again."
I'm curious what your opinion is of membrane theory for dark matter. I apparently independently came to membrane theory by listening to physicists talk about cosmological crises and would love someone who is actually working on this stuff to prove me wrong.
My idea of it basically revolves around the concept that gravity as we see it may be just that the gravitational force we can percieve in our frame of reference within the universe and actually gravity is about as strong as the other fundamental forces but is tempered in a way by the effects of dark matter and interactions either between universes, outside of the universe or in extra dimensions we cant percieve. So in effect the interactions of gravity on higher dimensions creates negative gravity wells that form dark matter halos as if the base of mountains collecting sediment which locks in gravitational objects into semi ordered structures. Also imo it provides some reasoning for the stable plateau energy state of the universe as it appears now, that this tempered gravity essentially acts as an anchor preventing the universe from continuing its phase decay of course unless the fundamental physics alter again like after the big bang.
Now of course a lot of this is essentially non falsifiable, we cant really peer into alternate universes or higher dimensions so feel free to dismiss these aspects. But to me it does sound like a solid explanation for how hard it is to actually percieve dark matter, that it isnt actually within your universe but is more akin to a gravitational shadow effecting it from the edges. (Edges in this case overlapping because space time isnt a box lol)
the expasion speed was higher at the beginings....just like an explosion ,the speed of particles/shrapnel is decreasing
Kurgesztadt and Dylan both liking dragon ball just proves that intelligent people like anime hahaha.
oh my god your videos have become so much better
Raccoons are Trash Pandas, Black Holes are Space Pandas.
Got it! :D
Stop correcting kurz when he's clearly implying not that they do exist but they possibly/might have existed...
So was this Black Hole Star theorized to explain the really HUGE black holes that we have in the universe?
Proud to be named after your cat!!!
Dylan! With the expansion of the universe still going on, is Earth experiencing the same effect of slowly being pushed away from the sun? Or is the gravity of the sun strong enough to "cancel" the effect?
Their problem is assuming a singularity as the beginning of the universe rather than an existing structure that emitted a very dense, but not infinitely dense, material soup. Curvature is local and the cosmological principle is false.
Bro Turned Into A Science teacher
He is
A physicist
Would love to see you reacting to videos from the channel "entire history of the universe" specifically the "beyond the edge" video
Check out Epic Mountain for the music Kurzgesagt uses. The Largest Black Hole theme they used in this video and the Black Hole Size Comparison Video is on their channel and all other songs as well. Would really recommend listening to those.
🤣 guy just goes over the whole video before even seeing it
I’m so glad I watched the vid first before seeing this coz it made it all the better
My only suggestion is making the video full screen and your camera/chat in a little box in the corners. Other than that I liked the video.
Goku would easily survive the heat of an black hole accretion disc and be able to escape it without issue.
Kurzgesagt didn't add UY Scuti it the comparison
Sad..
Aren’t anyone gonna talk abt him looking like Pewds in the thumbnail?
I agree with you. Im just a science junkiw. But the universe is simple yet extremely complicated all at once, so it like to let ya down sometimes. But if Quasi-Stars did exist then DAMN where they amazingly scary lol.
Gravitational waves also travel at the speed of light. So we are blind anyway.
Its not a death star because there is nothing to kill.
Did a physicist use the word nerd?
Americans are different being smart is not an insult in any other country maybe that's why they depend on importing smart people who contribute titanic proportions of skill wealth and taxes
what is difference between BH and neuyton star?
The music in this episode was so epically extra compared to the tone of the narration.
nice guitar
11:36 are people doing vs debates on celestial bodies lol?
15:46 nice
NGC 8550 BLACK HOLE IS 50 BILLION SOLAR MASSES
I think Dylan need to watch the videos and talk afterwards because kurg explains things later on in the vid and by then Dylan has already made a conclusion and false accusation to a kurg vid so Dylan if you see this just watch the vid and explain after or at least talk a little bit during kurgs intro
You could say a Black hole star could enter in the top ten.....anime betrayals! I'm out!
Black holes contain black energy and matter ..the energy and matter needed for the light to shine.. light and darkness need each other to exist and develop, Just thinking, without black holes stars wouldn't exist, for instance, nothing would exist, we came from black holes , same energy mind lives, is like death, a tranformation of energy and matter
but can it beat goku tho
Fun fact: The music in this video has played before this video. It is also the theme in kurzgesagt‘s The Largest Black Hole in the Universe - Size Comparison video too
That's very, very obvious though. Even the thumbnail are both similar.
Lol fine I won't start an anime discussion 🤣
Danm man i love this dude but the pauses ar deiving me crazy
Kurzgidaddy 🤔ayo Dylan
I don't want to be rude but why you using my name I've seen the video too
6dday slate
Kurzgedaddy omg
lol, Kamehamehaaaa
11:35 what
My bad, editing error, belonges at the blackscreen a minute later. The blackscreen should get cut out in some hours.
I will start an anime discussion. Goku could beat that black hole star.
ALWAYS GO FULL NERD
pls react to styropyro
yes it is a reaction video but he still got too excited and kept ruining the pacing of his video and Kurzgesagt video as well. also just noticed but Dylan didn't mention Kurzgesagt in the description or title. linking the original video or channel is the least you could do in a reaction video. immediate dislike
subscription earnt , mate
Yooo i just watched original video few minutes ago, might as well see your reaction too :)
4th! Hi dylan, good work
💀
