Its kinda cute how she is constantly confusing worm holes with black holes. She seems to believe the "hole" its literal and it opens portal to another place in the universe. No, Peko. It sucks, bends and destroy everything. That is why its a "hole" . You should know better being, you know, from a distant Peko-planet...
Not really on the sucking thing, as long as you're far away your safe. Kinda like planets, the sun etc as long as you're on a safe distance it ok, but once you get too near, gravity will take over I just want to clear that out, forgive me if it kinda sound complacent
If anything we dont know if black holes could be a portal to an infinitely different universe. Theres a popular theory suggesting that if you got sucked in faster than the speed of light and somehow managed to survive for an infinite amount of time and somehow got past the event horizon (yes a lot of conditions for this to work) you'd end up getting "shot" out of a "white" hole. A white hole is just a black hole but it spits things out faster than the speed of light. Now how this works I dont know jack shit about, but its a popular theory so
@@TonkarzOfSolSystem Also I believe wormholes are theoretically created when a white hole and a black hole collide with each other. Heard that in a documentary, it was quite interesting.
Physicist here. Interesting ideas, all of them, but they are over-exagerations used to try add some meaning to "dificult" to grasp concepts. As far as all evidence, and our current understanding goes, a black hole is a superdense mass with such a high gravitational pull that it actually attracts, bend, and pulls light. Now, for a long time, light was used as a refference for a lot of measurements, because it was thought to be a constant. Now we know it """is not""" (please notice the triple quotation marks) light is simultaneously a constant, AND a variable, depending on diferent "observation" frameworks: if we measure it on our current fourdimensional space, it is a constant, and behaves as such. If, however we treat time as a separate frame, we notice light starts doing some very abnormal stuff. Now, when talking about black holes, if you use light to measure distances, sizes, speeds etc, like with every other celestial body, you start getting weird feedback, because light (and arguably time itself, when observed as a simple non relativistic frame) is/are getting simultaneously affected, and not-affected, leading to those "time extending to infinite for traveler, but for observer is static" paradoxes. Wormholes are a whole different thing, if any is interested i could try to explain
I remembered when they announced they would try to make the first man-made black hole and no one really knew what was going to happen. There was real fear of the Earth just going "swoOOOP" right into it.
@@Lewisiaisoutofcontext As far as we can "tell," the subatomic blackholes we'd produce would evaporate faster than they could get near any matter. Now, gravity is still a big mystery to us because it's so weak and hard to measure. Maybe the Large Hadron Collider already produced micro black holes and they're so weak and short lived, they're undetectable.
As you cross the event horizon of smaller black holes you’ll be spaghettified, but the super massive ones (such as at the center of the Milky Way) you wouldn’t even realize you’d crossed the boundary, but you could still never get out.
I really hope if someone does a collab with her and they know about black holes to teach in a fun way. The fact she even watched something like that is good.
I'm screaming "schwarzschild radius", "hawking radiation", and "special relativity" at the top of my lungs, watching Pekora speak about these subjects can't be good for my health
This topic comes from a very... interesting topic in itself. > Talks about rabbit ears, if you work hard enough it'll grow > some commenters saying it grew out down below > Gets nasty and starts talking about some videos of people farting and possibly relieving themselves of a heavy burden in their pants, unsure if its real or prank > Comments complain of stinky conversation > Pekora asks for topic > Comment says Universe > Talks about Black Hole and asks someone to go into it just to see what will happen
This video is pain lol I could only imagine how much more painful it would've been if I had caught this stream live. Because I can't read or write Japanese, I can't correct her misunderstandings on black holes lol
I believe that there is a theory that A rotating Black hole: a Kerr-black hole, which had a ring singularity, no centre. Thus if we avoid the singularity, we can time travel, If Pekora discovered that then.....
1:58 "observation? like they threw a camera at it?" i would love to read that paper; "we threw a camera at a black hole and here's what we learned..." XD
Heres the thing pekora, we actually cant see the black hole with our eyes because light cant escape from it!! I bet you 2 dollars that pekora gonna be like "hah? Ofcourse we can see them, theres picture of it bakatare!"
No, this is an obsolete theory. See Hawking Radiation - black holes are their own source of light. I've typed it up the long version in response to Master3530's comment elsewhere to this video.
So for those wondering about Black Holes, these are an amateur's thoughts on the video. Take what I say here with a grain of salt, I'm skipping some technical stuff to, I hope, give you a good visualization. 0:10 "Apparently, if you enter a Black Hole you won't be able to get out." True, in fact, you'll reach the point of no return 'long' before you reach the Black Hole. Now this is often explained that the 'gravity is so great, even light cannot escape', but I always felt that didn't really explain why. So, mass distorts space(-time) and we call that distortion gravity. Black Holes are super massive things squeezed in a really small volume, so the distortion and thus gravity is about as extreme as it can get. So why can't you get out? Well imagine a dot with a small arrow sticking out in *every possible direction* and when that dot passes by a planet, every arrow is slightly bent towards that planet. Now imagine the Black Hole, the arrows don't bend slightly, but a lot. Really a lot. And as the dot gets closer and closer, at some point (this is the 'Event Horizon') every arrow, despite starting in a different direction, points deeper towards the Black Hole. There's *no physical direction* that you can take, that doesn't lead deeper into the Black Hole. That's why you can't get out. 0:25 "A person going towards a black hole, may seem like he's going on forever." Also mostly true. We 'see' things because there's radiation coming from objects that hit our detectors. Easiest; light hits an object, gets reflected, and detected by our eyes. Or flames produce, among other things, light that hits our eyes. So to see a person going into a black hole something needs to hit the person and then get reflected towards us, or the person has to emit it's own 'something'. BUT as previously discussed, past the Event Horizon, nothing can escape. So we actually stop seeing the person. What we're seeing is an 'after image' caused by light that didn't directly reflect towards us, but first spend some time circling the Black Hole just outside the Event Horizon. The longer one waits, the less of that light exists and escapes towards us. So we'd observe that person falling towards the Black Hole untill at some point the person stops and slowly fades. 0:43 "Why do Black Holes exist?" Stars 'burn' by fusing elements in their core into heavier elements. First hydrogen into helium and later those heavier elements in even heavier elements. Until iron, this element is essentially too stable to fuse through normal stellar means. But the difference in size of each element isn't that big, so the difference in 'weight' (i.e. *why* is it heavier) is because it's denser. So at the end of it's solar life a star has a much denser core that the pressure of the fusion radiation can no longer win against and the core collapses. This releases so much energy that the outer layers are blown away in an explosion several times the size of the solar system called a Supernova. A star that started with 10 times the mass of our sun (in fact, it's theorized only 3 times is needed) would go Supernova and end up a Black Hole with an Event Horizon of ~30 km in radius. 0:48 "Has none entered in a Black Hole yet?" In 2020 the star system HR 6819 was reasoned to contain a Black Hole and the closest one to Earth. While the findings of that particular study are contested by 2 others, 1 that argues there's no Black Hole at all, assuming it does contain a Black Hole. It's about 1120 light years (10 596 020 000 000 000 km) from Earth. That means even at the speed of light it'd take 1120 years to get there. For comparison Voyager 1 (launched in 1977 and the furthest man made object from Earth) is a mere 22 843 564 287 km or 21 light _hours_ away from Earth. So no; noone has been to a Black Hole yet- they're too far away. 0:53 "But are Black Holes really pitch dark?" Since nothing can escape the Event Horizon that surrounds a Black Hole and thus they themselves emit literally nothing even could be observed from the outside; yes they are pitch dark. 0:56 "Those who enter a black hole, do they exist in the same realm as us?" Easy answer; yes but in the most extreme conditions possible in the universe. Difficult answer; like how my physics teacher said when I wondered aloud of matter is merely condensed energy "let's not yet go there for the next couple of years...". 1:13 "Eh? But you can see a Black Hole..." Technically you can't. But we can infer it's existence and quite a lot of properties by how the universe around it behaves. 1:18 "People get bent?" This is referred to as Spaghettification. Basically once you go past the Event Horizon the gravity becomes even more extreme, so extreme that the gravity you experience at your feet and head are so significantly different that you'd be stretched (also your left will be pushed to the right and your right will be pushed to the left) and destroy your body. 1:37 "But how do you guys know that?" This is where the wonderful practice of inferrence (among others) comes in. You see, we've been using mathematics (advanced mathematics, but mathematics nonetheless) to describe the universe quite accurately. And because of that we can infer things from what we see. If you look at a lake and there are big circular ripples going from the center to the shore then someone probably dropped a fairly big rock in the middle, even if you didn't see it and can't find the rock while snorkling. So too did we use mathematics to predict the existence of Black Holes before we found them. And when we found a black hole, we couldn't see it, but we could see everything around it behaving as if there was a Black Hole around. If you want to do some work of your own search in your preferred search engine for images for "Milky Way Black Hole gif". Chances are at least one or two of them are about how we first discovered the Black Hole at the center of the Milky Way galaxy; by looking at other stars. 1:48 "You have to experience it first-hand to know about it right?" Well, not first-hand. Else how do you know what you know about Black Holes Pekora? You saw it in a video so that's, at best, second-hand. But it's not entire untrue either. There's a lot we don't know exactly because we haven't been there. Mathematical models are nice in easy circumstances, but when it concerns Black Holes or the Big Bang, the conditions are so extreme that a lot of our maths breaks down. 2:28 "I wonder if you can make a Black Hole?" In theory; totally. You just need to get something dense enough, compact something smaller than it's Schwarzschild radius. The 'easiest' way to do that is with particle accelerators. Years ago, people who didn't know what they were talking about, were afraid that CERNs LHC would produce Black Holes and destroy the Earth. Scientists who actually knew what they were talking about were like "It'd be pretty cool if we managed to create Black Holes." But instead of taking that as a sign that there would be no danger, morons took that to mean that apparently scientists crave death, want others to die, and worship satan. A lot of people imagine that Black Holes are these giant vacuum cleaners or other wise attract things and destroy everything, but the simple truth is that the attraction part comes from gravity, which is governed by mass. So if I had 2 electrons, smashed them together and created a Black Hole, I'd have a Black Hole with the massive attraction of... 2 electrons. Gravity wise, nothing would've changed. Plus, without going into details, due to the unique nature of Event Horizons Black Holes actually slowly evaporate anmd the smaller they are the quicker they evaporate. A Black Hole the mass of electrons would exist for such a short time that there's actually no shorter time possible! Still, even the LHC didn't make a Black Hole (as far as we can tell anyway). So practically; no you can't make a Black Hole. Note: You don't need to capitalize Black Hole or practically anything I capitalized. I just did that to make important terms more recognizable. All things considered, Pekora and chat got a lot right about Black Holes and the difference was mostly in details that even science journalists might skip. Though I do believe them to be important to know.
Her curiosity is admirable. But even experts have more questions than answers regarding the science about black holes. So, we are all *basically still* on the same boat, Pekora.
@@Purpletrident Space does have quite a bit of matter in it, usually around a few million atoms per m³. You'd need to compress that matter a lot and depending on the size you want your black hole to be you'd need a lot of space to pull matter from, but space is GIGANTIC, so technically you could make black holes from "space air".
She just hit the elementary kid phase of knowing too much stuff about black holes Also she has gone from normal to war criminal to super villain in the span of a year
Actually no, they're not so dark because of Hawking Radiation. Light can't escape so any photons that come from a star and reach the black hole never gets out. But the black hole is itself a source of photons - virtual photon/anti-photon pairs spontaneously form and destruct in the vacuum. When this happens on the event horizon, one photon gets sucked into the black hole, its partner must become real and is on a trajectory outward. The energy cost to make that virtual photon real is 'paid' by the black hole.
When photons and anti-photons exist, anti-photons absorbed back to the blackhole while the virtual photon become real and escape from blackhole through hawking radiation. Since anti-photons carry negative energies, it will reduce blackhole mass gradually until the blackhole evaporate completely.
Little did we know, in 5 years Pekora quit Hololive to pursue a doctorate in physics and invents a way to make stable mini-blackholes that would swallow earth and end humanity.
It's funny the way she thinks about Black Hole like it's some kind of big ravine where she can throw anything in there safely as long as you she keeps her distance.

Theres a popular theory suggesting that if you got sucked in faster than the speed of light and somehow managed to survive for an infinite amount of time and somehow got past the event horizon (yes a lot of conditions for this to work) you'd end up getting "shot" out of a "white" hole. A white hole is just a black hole but it spits things out faster than the speed of light. Now how this works I dont know jack shit about, but its a popular theory so
Wormholes are black holes in the sense that they form the some way. However wormholes are entirely theoretical and yet to be observed.
@@TonkarzOfSolSystem Also I believe wormholes are theoretically created when a white hole and a black hole collide with each other. Heard that in a documentary, it was quite interesting.
Physicist here. Interesting ideas, all of them, but they are over-exagerations used to try add some meaning to "dificult" to grasp concepts. As far as all evidence, and our current understanding goes, a black hole is a superdense mass with such a high gravitational pull that it actually attracts, bend, and pulls light. Now, for a long time, light was used as a refference for a lot of measurements, because it was thought to be a constant. Now we know it """is not""" (please notice the triple quotation marks) light is simultaneously a constant, AND a variable, depending on diferent "observation" frameworks: if we measure it on our current fourdimensional space, it is a constant, and behaves as such. If, however we treat time as a separate frame, we notice light starts doing some very abnormal stuff. Now, when talking about black holes, if you use light to measure distances, sizes, speeds etc, like with every other celestial body, you start getting weird feedback, because light (and arguably time itself, when observed as a simple non relativistic frame) is/are getting simultaneously affected, and not-affected, leading to those "time extending to infinite for traveler, but for observer is static" paradoxes. Wormholes are a whole different thing, if any is interested i could try to explain
"Hey guys v-sauce peko here,today we gonna talk about black hole and how to create them"
Cursed
"Apparently if you enter a Black Hole, you can't come out."
What bothers me is how she doesn't realize the Pekora rabbit hole IS a black hole
"I wanna make a tiny black hole"
This seriously reminds me of how the universe is endangered whenever Haruhi is feeling bored
Man... Nousagis can literally keep up on Pekora's tangents
Well, if they can keep up with shit like animal and human cloning with her, why not black hole?
The Nousagi alliance is vast. No matter what academic tangent she goes off on, there will be experts who can elaborate.
My head hurts when she said using space air and meteorite to make black hole.
She’s asking too many questions, we can’t tell her
Well. People are able to make artificial black holes but their destruction power are so weak that people don't have to worry about it
Yes it is you need a bigger facility to make a quantum collider correct me pls.
I remembered when they announced they would try to make the first man-made black hole and no one really knew what was going to happen. There was real fear of the Earth just going "swoOOOP" right into it.
@@reinjocastaneda8759 To be honest, I only get the gist of how it works. I could only answer, probably.
@@Lewisiaisoutofcontext As far as we can "tell," the subatomic blackholes we'd produce would evaporate faster than they could get near any matter. Now, gravity is still a big mystery to us because it's so weak and hard to measure. Maybe the Large Hadron Collider already produced micro black holes and they're so weak and short lived, they're undetectable.
We made one that only works on sound in a lab.
Scientists: There must be dark matters filling the empty space
Pekora: *s p a c e a i r*
the frustration of wanting to explain something to someone and realized u can't
As you cross the event horizon of smaller black holes you’ll be spaghettified, but the super massive ones (such as at the center of the Milky Way) you wouldn’t even realize you’d crossed the boundary, but you could still never get out.
Even though most of this seems like common knowledge, it's interesting to get her perspective and first-time thoughts on black holes.
And now she's about to commit crimes on a galactic level
I really hope if someone does a collab with her and they know about black holes to teach in a fun way. The fact she even watched something like that is good.
she's like a kid who has learned an interesting word, got fascinated and couldnt stop uttering it 🤣🤣
chat: people get bent
pekora: ooooohhhh
me: oh no..
Pekora seems to think a black hole is something you can get in your backyard to do tiktok challenges with.
Inside a black hole is an alternate universe where Pekora has green hair...they must never meet
You can definitely tell that she’s a great vtuber, and not a physicist; she’s cute as always.
I'm screaming "schwarzschild radius", "hawking radiation", and "special relativity" at the top of my lungs, watching Pekora speak about these subjects can't be good for my health
I love when Pekora gets into these type of conversations
This topic comes from a very... interesting topic in itself.
> Talks about rabbit ears, if you work hard enough it'll grow
> some commenters saying it grew out down below
> Gets nasty and starts talking about some videos of people farting and possibly relieving themselves of a heavy burden in their pants, unsure if its real or prank
> Comments complain of stinky conversation
> Pekora asks for topic
> Comment says Universe
> Talks about Black Hole and asks someone to go into it just to see what will happen
She forgot that she can create a singularity by removing one of the carrots on her hair.
This has been Exploring the Universe with Usada Pekora.
man I love whenever she gets on these topics
I love how Pekora is always curious about stuff
pekora: i want to creat a blackhole!
This video is pain lol I could only imagine how much more painful it would've been if I had caught this stream live. Because I can't read or write Japanese, I can't correct her misunderstandings on black holes lol
Pekora is not only laughter and war crimes, she's also a science curious bunny
It's always an adventure when Pekora randomly goes all in on some oddly specific but random topic
It's always a treat when pekora talks about the earth or space. It also makes me lose about as many brain cells as an hour of aqua's flute bgm does.
I believe that there is a theory that A rotating Black hole: a Kerr-black hole, which had a ring singularity, no centre. Thus if we avoid the singularity, we can time travel,
If Pekora discovered that then.....
*Amelia Watson has entered the chat*
Olivia has entered the chat
I love when she goes on these sort of scientific or philosophical rambles
pekora development, from a flat earther now a sciences nerd
You know, now I am curious too. This is a very interesting question-
In following news: Local rabbit discovers Extra-Over Technology and develops a functional Black Hole Engine
From war criminal to potential universe destroyer, Pekora continues to evolve each day as we speak
1:58 "observation? like they threw a camera at it?" i would love to read that paper; "we threw a camera at a black hole and here's what we learned..." XD
Heres the thing pekora, we actually cant see the black hole with our eyes because light cant escape from it!!
I bet you 2 dollars that pekora gonna be like "hah? Ofcourse we can see them, theres picture of it bakatare!"
No, this is an obsolete theory. See Hawking Radiation - black holes are their own source of light. I've typed it up the long version in response to Master3530's comment elsewhere to this video.
@@Psieye ohhhhh
Thank you for telling me that
Oh god, she's planning to develop a weapon that creates blackholes
twitter.com/Schverika1/status/1403129602663489540
Got you covered. It's even named after her dead pet: "The End"
You can't make a black hole, but you can make a rabbit hole, which pulls most, if not all of us already, Pekora.
Again with Pekora and her mindblowing knowledge from Pekoland.
Pekora: I wanna make a black hole.
Me: *Thinking about the greatest war crime on entire solar system* Sasuga Pekora sama.
Pekora, not content with her war crimes, upgrades to physics-based crimes
So for those wondering about Black Holes, these are an amateur's thoughts on the video. Take what I say here with a grain of salt, I'm skipping some technical stuff to, I hope, give you a good visualization.
0:10 "Apparently, if you enter a Black Hole you won't be able to get out."
True, in fact, you'll reach the point of no return 'long' before you reach the Black Hole.
Now this is often explained that the 'gravity is so great, even light cannot escape', but I always felt that didn't really explain why.
So, mass distorts space(-time) and we call that distortion gravity. Black Holes are super massive things squeezed in a really small volume, so the distortion and thus gravity is about as extreme as it can get. So why can't you get out? Well imagine a dot with a small arrow sticking out in *every possible direction* and when that dot passes by a planet, every arrow is slightly bent towards that planet. Now imagine the Black Hole, the arrows don't bend slightly, but a lot. Really a lot. And as the dot gets closer and closer, at some point (this is the 'Event Horizon') every arrow, despite starting in a different direction, points deeper towards the Black Hole. There's *no physical direction* that you can take, that doesn't lead deeper into the Black Hole. That's why you can't get out.
0:25 "A person going towards a black hole, may seem like he's going on forever."
Also mostly true. We 'see' things because there's radiation coming from objects that hit our detectors. Easiest; light hits an object, gets reflected, and detected by our eyes. Or flames produce, among other things, light that hits our eyes. So to see a person going into a black hole something needs to hit the person and then get reflected towards us, or the person has to emit it's own 'something'. BUT as previously discussed, past the Event Horizon, nothing can escape. So we actually stop seeing the person. What we're seeing is an 'after image' caused by light that didn't directly reflect towards us, but first spend some time circling the Black Hole just outside the Event Horizon. The longer one waits, the less of that light exists and escapes towards us. So we'd observe that person falling towards the Black Hole untill at some point the person stops and slowly fades.
0:43 "Why do Black Holes exist?"
Stars 'burn' by fusing elements in their core into heavier elements. First hydrogen into helium and later those heavier elements in even heavier elements. Until iron, this element is essentially too stable to fuse through normal stellar means. But the difference in size of each element isn't that big, so the difference in 'weight' (i.e. *why* is it heavier) is because it's denser. So at the end of it's solar life a star has a much denser core that the pressure of the fusion radiation can no longer win against and the core collapses. This releases so much energy that the outer layers are blown away in an explosion several times the size of the solar system called a Supernova. A star that started with 10 times the mass of our sun (in fact, it's theorized only 3 times is needed) would go Supernova and end up a Black Hole with an Event Horizon of ~30 km in radius.
0:48 "Has none entered in a Black Hole yet?"
In 2020 the star system HR 6819 was reasoned to contain a Black Hole and the closest one to Earth. While the findings of that particular study are contested by 2 others, 1 that argues there's no Black Hole at all, assuming it does contain a Black Hole. It's about 1120 light years (10 596 020 000 000 000 km) from Earth. That means even at the speed of light it'd take 1120 years to get there. For comparison Voyager 1 (launched in 1977 and the furthest man made object from Earth) is a mere 22 843 564 287 km or 21 light _hours_ away from Earth. So no; noone has been to a Black Hole yet- they're too far away.
0:53 "But are Black Holes really pitch dark?"
Since nothing can escape the Event Horizon that surrounds a Black Hole and thus they themselves emit literally nothing even could be observed from the outside; yes they are pitch dark.
0:56 "Those who enter a black hole, do they exist in the same realm as us?"
Easy answer; yes but in the most extreme conditions possible in the universe. Difficult answer; like how my physics teacher said when I wondered aloud of matter is merely condensed energy "let's not yet go there for the next couple of years...".
1:13 "Eh? But you can see a Black Hole..."
Technically you can't. But we can infer it's existence and quite a lot of properties by how the universe around it behaves.
1:18 "People get bent?"
This is referred to as Spaghettification. Basically once you go past the Event Horizon the gravity becomes even more extreme, so extreme that the gravity you experience at your feet and head are so significantly different that you'd be stretched (also your left will be pushed to the right and your right will be pushed to the left) and destroy your body.
1:37 "But how do you guys know that?"
This is where the wonderful practice of inferrence (among others) comes in. You see, we've been using mathematics (advanced mathematics, but mathematics nonetheless) to describe the universe quite accurately. And because of that we can infer things from what we see. If you look at a lake and there are big circular ripples going from the center to the shore then someone probably dropped a fairly big rock in the middle, even if you didn't see it and can't find the rock while snorkling. So too did we use mathematics to predict the existence of Black Holes before we found them. And when we found a black hole, we couldn't see it, but we could see everything around it behaving as if there was a Black Hole around. If you want to do some work of your own search in your preferred search engine for images for "Milky Way Black Hole gif". Chances are at least one or two of them are about how we first discovered the Black Hole at the center of the Milky Way galaxy; by looking at other stars.
1:48 "You have to experience it first-hand to know about it right?"
Well, not first-hand. Else how do you know what you know about Black Holes Pekora? You saw it in a video so that's, at best, second-hand.
But it's not entire untrue either. There's a lot we don't know exactly because we haven't been there. Mathematical models are nice in easy circumstances, but when it concerns Black Holes or the Big Bang, the conditions are so extreme that a lot of our maths breaks down.
2:28 "I wonder if you can make a Black Hole?"
In theory; totally. You just need to get something dense enough, compact something smaller than it's Schwarzschild radius. The 'easiest' way to do that is with particle accelerators. Years ago, people who didn't know what they were talking about, were afraid that CERNs LHC would produce Black Holes and destroy the Earth. Scientists who actually knew what they were talking about were like "It'd be pretty cool if we managed to create Black Holes." But instead of taking that as a sign that there would be no danger, morons took that to mean that apparently scientists crave death, want others to die, and worship satan.
A lot of people imagine that Black Holes are these giant vacuum cleaners or other wise attract things and destroy everything, but the simple truth is that the attraction part comes from gravity, which is governed by mass. So if I had 2 electrons, smashed them together and created a Black Hole, I'd have a Black Hole with the massive attraction of... 2 electrons. Gravity wise, nothing would've changed. Plus, without going into details, due to the unique nature of Event Horizons Black Holes actually slowly evaporate anmd the smaller they are the quicker they evaporate. A Black Hole the mass of electrons would exist for such a short time that there's actually no shorter time possible!
Still, even the LHC didn't make a Black Hole (as far as we can tell anyway). So practically; no you can't make a Black Hole.
Note: You don't need to capitalize Black Hole or practically anything I capitalized. I just did that to make important terms more recognizable.
All things considered, Pekora and chat got a lot right about Black Holes and the difference was mostly in details that even science journalists might skip. Though I do believe them to be important to know.
Always love this Karl Pilkington session of her chit-chat.
Nah, she's not as strongly opinionated. Pekora is more of a Katy Perry.
Her curiosity is admirable. But even experts have more questions than answers regarding the science about black holes. So, we are all *basically still* on the same boat, Pekora.
I wonder if there exists "space air" to build a black hole. Anyway, why all that interest all of a sudden?
Any ”air” that is thrown into space would chunk together into a sphere due to gravity. How do you think Gas Giants work?
Space is a vacuum so you can't exactly grab some air in space
@@Purpletrident Space does have quite a bit of matter in it, usually around a few million atoms per m³. You'd need to compress that matter a lot and depending on the size you want your black hole to be you'd need a lot of space to pull matter from, but space is GIGANTIC, so technically you could make black holes from "space air".
She just hit the elementary kid phase of knowing too much stuff about black holes
Also she has gone from normal to war criminal to super villain in the span of a year
From civil war criminal, Pekora advancing to become Universe Villain.
YABE.
The first thing that pops to my head when this rabbit talks about black hole is "somebody stop her!!! She'll destroy humanity!!!"
That crazy space air. You can perform unbelievable miracles with that stuff!
The peko is finally curious about life and science! Ah, what a development.
"Are they really pitch black?" Yes, that's the point, even light can't escape its gravity.
Actually no, they're not so dark because of Hawking Radiation. Light can't escape so any photons that come from a star and reach the black hole never gets out. But the black hole is itself a source of photons - virtual photon/anti-photon pairs spontaneously form and destruct in the vacuum. When this happens on the event horizon, one photon gets sucked into the black hole, its partner must become real and is on a trajectory outward. The energy cost to make that virtual photon real is 'paid' by the black hole.
When photons and anti-photons exist, anti-photons absorbed back to the blackhole while the virtual photon become real and escape from blackhole through hawking radiation.
Since anti-photons carry negative energies, it will reduce blackhole mass gradually until the blackhole evaporate completely.
Little did we know, in 5 years Pekora quit Hololive to pursue a doctorate in physics and invents a way to make stable mini-blackholes that would swallow earth and end humanity.
I slap myself whenever Pekora starting to talk about science stuff www its entartaining and hilarious at the same time
being an astronomy enthusiast really gives you a hard facepalm seeing her questions 😂
It's funny the way she thinks about Black Hole like it's some kind of big ravine where she can throw anything in there safely as long as you she keeps her distance.
This rabbit is too naiive to know the dangers of a black hole
Pekora: talking about blackhole
me: pull the carrot on Pekora's braid
pekora: learns about horrifying space entities that could destroy the universe
also pekora: "can you make a black hole?"
i wonder if they could get permissions for universe sandbox, i'd love to see pekora think up so many ways to destroy
Pekora next project : ultimate weapon mini black hole
whoever give her an idea of blackhole is a threat of humanity.
"If the Earth is destroyed, will we go to Mars?"
All humanity, *NEVER* mention this rabbit ways to destroy the Earth anymore. She will actually try it
Pekora's mind is also a mystery of the universe.
I love when she talks about these kind of things lol
You know, I used to wonder how the average score for Choco's quiz was 7 points. Now I'm surprised it was that high. These girls really didn't pay attention to anything in school
