Vtuber Learns To NOT Meddle with Black Holes | Channie Reacts to Kurzgesagt-In a Nutshell

[@rexosuitmk2577]

A banana, under normal circumstances, cannot make a black hole. But if someone somehow made a machine that could crush a banana to an incredibly small volume (probably smaller than an electron), then the resulting crush will form a blackhole.

[@VV.O.l.D.]

everything has mass and everything with mass (so literary everything), CAN be a black hole if condensed enough, but it would be basically impossible

[@C3R133RUZ]

In regards to black holes, NASA has quoted "Almost every large galaxy, including our Milky Way, has a supermassive black hole at its center....Binaries have revealed around 50 suspected or confirmed stellar-mass black holes in the Milky Way, but scientists think there may be as many as 100 million in our galaxy alone.".

[@ChanniePlus]

holy, that's A LOT. Thank you for the info!

Should have coded in Python

[@The-Real-Sanga]

@@kejrr-c2lnah they should try scratch trust

[@dashoob504]

Black holes are just a string god forgot to give a value too so it's null, waiting to break the universe the moment it's called

[@louisrobitaille5810]

1:40 A black hole does get bigger whenever it consumes stuff, but it's something we don't fully understand yet as supermassive black holes break our models. They shouldn't exist yet according to our current best models.

[@MySerpentine]

An event horizon isn't a physical object, it can't crack. It's just the point of no return: either you can return from the area around a singularity or you can't.

[@Circle9ru]

11:12 there can't be a crack in event horizon. event horizon is NOT the surface. that black sphere you see(or most likely not see) is just an area nothing can escape from. you can't land on it or touch it, its not solid, not liquid, not even gasseous or plasma, its just a place nothing comes from. its basically as if you draw a line and said "beyond this line is my territory", the event horizon is not the line, its that exact place betwin one side of the line and another. i don't know what analogy is best here, imagine non-physical border, like a border betwin two countries but in the sky, there's nothing there, but the sky still devided to yours and theirs in that place. you can't crack empty space, at least modern physics don't know about it.

[@ChanniePlus]

that example actually helped a lot, thank you for explaining!

[@themathgod9567]

in our observable universe there is 10 to power of 17 black holes that we can see that is 1 followed by 17 zeros or one hundred quadrillion

[@whothefrickareyou8106]

1:33 You could watch their video about black holes "What if you fell into a black hole"

[@aasishwarsaravana5748]

Love Vtubers racting to Kurzgesagt! Super knowledgeable and high quality videos!

[@HiroSuiOfc]

12:18 idk if someone already told you about but every galaxy has at least 1 black hole that is in the center of the galaxy, thats why its like a espiral

[@9308323]

Untrue. Most large galaxies are _believed_ to have them, but there are examples of galaxies which we believe don't, like M33.

[@zero3762]

As far as i know the event houzon isn't a physical thing. It's more of a visual thing. Also in the center of every galaxy is a supermassive black hole that holds the galaxy together and many normal ones as well. Of course correct me if i'm wrong.

[@louisrobitaille5810]

It's not the supermassive black hole that holds the galaxy together, it's the dark matter 😅. Also every galaxy has a supermassive black hole 😛. You're right about the event horizon though, it's just the point where the gravity is strong enough to prevent light from escaping 👀.

[@arnabbiswasalsodeep]

"Stellar engine" and "terraforming venus" would be my next suggestion, "nuke the moon" and "moon falling to earth" would be by next pair of suggestions. "largest star" & "largest black hole" are good to watch in series

[@ChanniePlus]

thank you for the suggestions, I will note them down!

[@Zagaroth]

If you compress anything small enough relative to its mass, it turns into black hole. Bannanna was just them throwing in something silly to make that point. :) Also, a charge of "zero" is a valid value for a black hole, as is any other value. Something like an electron only has one valid value for a charge. If you like this stuff, PBS Spacetime might be a good channel for you to watch. It's not done in as fun a style, but they are trying just as hard to communicate this type of information. :) An event horizon is sort of a yes/no thing. It's either there or not. Regarding the number of black holes in the Universe: Infinite. For the Galaxy: unknown, but a lot, and a really big one in the center.

[@ChanniePlus]

thank you for taking from your time to answer my questions, I appreciate it! ^.^

[@louisrobitaille5810]

As far as we know, nothing is infinite in the universe. Sure, there might be a LOT of black holes, but not infinitely many.

[@Zagaroth]

@louisrobitaille5810 to the best we can measure, the universe is completely flat. This implies an infinite universe. In an infinite universe, there is an infinite number of anything that occurs regularly.

[@louisrobitaille5810]

11:17 Event horizons are just the point at which the gravity is strong enough to prevent light (and therefore literally anything else) from escaping. That's why it appears black. It's not something that can be interacted with. If you were to fall into a black hole, you couldn't tell when you did and nobody from the outside could tell either. They'd just see your body stop in place, then slowly disappear as if you were evaporating.

[@Zazu1337]

The Problem with the hawking radiation is that even the CMB is stronger then the Hawking radiation. So _aCtUaLLy_ black holes decay slower then they grow even if no mass is around for them to feed on. Arstrophysics is wierd... xD (CMB = Cosmic microwave background)

[@ChanniePlus]

oooh I see, also thank you for the CMB explanation I was gonna ask what it was xD

[@rexosuitmk2577]

4:08 For particle charges, don't think of them as multiplying. In multiplication, - times - gives a +, - and + gives -, and + and + gives plus. For this circumstance, charges are added, not multiplied. So, +1 plus -1 (since the charges are equal) would give 0, a neutral number neither negative nor positive. A neutral charge is, technically, a charge. It just equals 0.

[@Denzao-D]

There are black holes everywhere. Not counting our super massive black hole in the middle. We discover new black holes everywhere all the time. Some are pretty close to us. Everything in space is massive. Time, for example. According to the cosmic calendar(to better understand how small we are), we humans here are like 30 seconds old in this calendar. Today, right now, the time is 11:59pm and 59 seconds on the 31st of december. Big bang happened close to midnight the 1st january, We are nothing compared to the universe. We are just some bacteria who were lucky to be allowed to exist. So in that meaning a black hole for us is quite far away but in space distance they are very close and they move fast

[@ManfredDudesonVonGuy]

1:33 "Does a black hole get bigger the more it consumes?" Both! It depends on what you mean by "black hole". If you mean the area in space where the gravity is too strong for light to escape, then yes, more mass or energy entering makes the black hole larger. However, if you mean the thing *causing* that area of space, that would be the singularity at the center*. A singularity is a point of infinite density and since density is mass divided by the space that mass takes up (mass/volume), the only way to achieve infinite density is to have 0 volume (calculus gets rid of the divide by zero problem). In that sense, no matter how much stuff you shove into a singularity, it will never grow, by definition. *oh he got to it nvm

[@KodFrostwrath]

11:40 philosophical Channie moment xD

[@ChanniePlus]

So real xD

[@louisrobitaille5810]

13:20 Now you understand just how young the universe is, despite being ~13,8 billion years old 😂.

[@grindersongear759]

Technically anything and everything can become a black hole if put under the correct conditions which usually involves condensing and compressing it down to astronomically small level it can't possibly contain its own Mass and breaks physics in the process However to say this is nearly impossible to do is a bit of an understatement and as far as I'm aware us humans have never been really able to replicate this and really the only things capable of doing this are the things that turn into black holes normally

[@Techno_Idioto]

All it takes is to crush something down to below its Schwarzchild Radius and you'll get a black hole....or if you compress enough energy into one spot, you can also create a black hole known as a Kugelblitz.

[@thexlonewolf671]

The thing I find really crazy about black holes isn't the fact that space and time switch jobs inside a black hole, the properties of the singularity, or even the fact that they have theoretically infinite energy due to having infinite gravity. It's the fact that the existence of black holes implies infinite parallel universes. Veritasium's "Something strange happens when you follow Einstein's math" video has more details, but the short version is that black holes rotate, which causes the singularity to act more like a portal to a white hole, a black hole's theoretical opposite, where no matter what happens, if you are inside it, you have to be ejected. It's a really interesting idea.

D: we miss you too

[@ChanniePlus]

T^T

[@aahilhossain-my7xl]

Hey great idea to react to these type of videos, many people love Kurzgesagt (especially reaction videos), also if I remember right you should have no legal issues as Kurzgesagt loves these types of videos aslong as you give credit. I am not a usual viewer of your channel but you popped up even with such a low view count. I really wish you luck on your endeavors, the fact I got recommended this video means that the youtube algorithm is not working against you. Even when things get tough don't give up cuz handwork always pays of and don't forget to have fun while doing it. I prb won't get any of your videos recommended again anytime soon but I still want to wish you luck on your journey if your reading this.

[@Oliver-hg4tu]

I feel bad for your fingers if i did that they would hurt but thanks for the info

[@ChanniePlus]

thank you so much for the encouragement! ^.^

[@FlavioSantos-uw1mr]

General Relativity is not exactly my area, but trying to explain it simply, an event horizon represents a place where information cannot reach you,for example when you move a horizon "forms" behind you only VERY far away, how close it gets is proportional to your speed, but they are not physical barriers that can be touched, You could fall into one and not notice the passage on the horizon, as long as you didn't hit a wall of fire and energy on the other side of what fell there before you. So no, you can't have cracks in it, but they can have other shapes that aren't spherical, in fact in most cases their structures are quite complex.

[@ChanniePlus]

ooh that's so interesting! Thank you for the simple explanation!

[@nzqarc]

We do have a black hole in our galaxy, in fact, it's in the center of our galaxy like how the sun is in the center of our solar system. Every galaxy has a black hole at it's center. Our black hole is named Sagittarius A*

[@louisrobitaille5810]

4:06 Charges are numbers. +1 + -1 = 0. A "+" alone makes no sense (in this context). There’re 3 types of charge: positive (+x) negative (-x) and neutral (0).

yo!!! can you react to kurzgesagt world war of the ants, pls

[@twilink5810]

Beautiful avatar

[@Koko_clair]

Singularity beautiful name isnt it?

[@RealILOVEPIE]

hangon wouldn't a white hole be it's antipartical?

[@demian_csomic_winters9484]

I wonder if black hole gets too big and breaks apart could that be an explanation cause of so big bang assuming big bangs are real as to have happened?
