@@junholee4961 but the point is that nobody *thinks* of it as converting mass into energy, much as they don't for chemical reactions. The mass lost is too insignificant.

I think it might be in reference to a famous 1960 paper titled: "The unreasonable effectiveness of Mathematics in the Natural Sciences" but it's just a guess.
The math is way off in this video. Everybody knows that cats have 9 lives, so each cat can convert 9 times and thus all these numbers should be divided or multiplied by 9 depending upon which direction we're doing the conversions. Remember folks: reduce cat overpopulation, reuse cats up to 9 times and recycle their litter too (it smells bad, might as well burn it away at the same time).
Why burn the litter if you could just throw it into the black hole? It's more efficient and doesn't smell as bad. Besides cats can't have 9 lives because it would mean there's like 378% efficiency in their case, which obviously violates the 2nd law of thermodynamics.
Because of that, Cats can generate more energy than an Gamma-Ray-Burst, and would thereby make almost the entire Universe collapse. That is why alien live has ceased to exist.

I _think_ yes, but asymptotically far into the future for any frame of reference further outwards than the cat's. So if you want to actually see the cat land, you have to throw yourself in at the latest with the cat, if not just ahead of the cat.
With a small enough black hole, you can convert 100% of the infalling mass to energy. Small ones are "hot" and have significant Hawking radiation. So you get one that's the right size to produce the power you want and then throw in mass periodically to keep it from getting smaller. If you stop feeding it, it shrinks, gets hotter and radiates faster and eventually blows up. But keeping it in balance is pretty easy if you are talking power needs along the lines of Norway or the world. Trickier if you want really gigantic power production from a smaller black hole.
Black Hole Studios I like how you said "I know that's not that much" because you probably used to learn the imperial system in school but you're also proud of yourself and think it makes you look smarter because you know the metric system. :D
Humans spend so much time trying to define what elements they associate with humanity. If aliens see humans, humanity's associated element would be spinning turbines.
I prefer weed jokes as opposed to ones that get me started on thinking about the meaning of life, leading to me realising how pathetic my existence is.
So the question to the answer of life, the universe and everything might just be - "What percentage of mass is converted into energy as it orbits a black hole which is spinning as such speed that its innermost possible orbit coincides with its event horizon?"
Even at 10 cats per Norway per year, that's awesome! And cats are a renewable energy source; so, we'd be set for at least a couple hundred million years!
@@Alexander99602 Google Penrose process. You can literally extract energy from a black hole on the expense of its rotation. Basically, you'd have to throw a cat into the region called ergosphere (which is the region where things cannot stay stationary anymore) with the right amount of speed and in certain direction. End product is the cat (unfortunately to be more precise, a part of the cat) emerging out with more kinetic energy than she initially had.
I wish my math teacher would explain things with examples like how to power Norway with cats instead of just boring stuff directly from the textbook that was made specifically to cover only the curriculum on the test at the end of the course, not made so we actually retain any of the information. I'm way more likely to remember this than some of the boring things in my algebra 2 class, and I probably don't even understand this very well compared to algebra 2 which is really easy. I'm so glad people make educational stuff on youtube.
There's an even better solution to this with rotating black holes. You can directly harvest the rotational energy of the black hole through superradiance of lasers. Surround it in a reflective surface - or more likely arrange wave guides in specific patterns, and superradiant scattering will dump huge amounts of energy into the laser drawn from the rotational energy of the black hole
GetYours this annoys me. You realise that the timestamp won't work because it sends you to the beginning of the second, and anyone who watches the video would know where it was so they can go look.
The first couple of minutes of this video are very good. I appreciate the good analogies which explain clearly how much of an object's mass is lost in a typical reaction. Unfortunately, the rest is almost completely wrong. This is because when an object falls into a black hole, the radiated energy comes from its gravitational potential energy, _not_ from its mass. The mass doesn't change in such a process. The main mistake being made here is to ignore the black hole itself as a component in the reaction: there is indeed some conversion of "mass into energy", but it's not the mass of the cat, but the mass of the _combined black hole and cat system._ For a rotating black hole, you're actually extracting energy from the black hole's rotation (see: Penrose process). I at first thought that this video would make the case that black holes convert mass to energy completely because they eventually evaporate if you wait a _really_ long time. This would be a better case to make in this context, though you also have to take into account the thermodynamic efficiency in extracting such energy (Hawking radiation is thermal).
I thought the same. Of course you could argue that since energy is mass, the radiated energy comes from the object's mass (not sure how to view potential energy, though). However, in this case, the video's topic of "conversion" doesn't make any sense, really. And yeah, hawking radiation hasn't been mentioned for some reason.
If I understand you correctly, I wouldn't say "the rest is almost completely wrong". I think the video is just focusing on the conversion efficiency and not getting into the details of how this type of mass/energy conversion is somewhat different than the previous examples they cite. Yes you're right: In this case the mass is being converted to energy by an "outside" assist (the black hole), but there is still a mass-to-energy conversion happening in the overall process.
The language of "mass to energy conversion" is a bit sketchy at the best of times because, strictly speaking, it's category error. Nothing gets "converted" into energy because energy is conserved, rather, it's energy that used to be associated with rest mass that gets converted to kinetic energy of some particles or fields, typically photons. Here it is much worse because it gives the impression that the body gets lighter as it falls down the black hole. On the contrary: if you went alongside the object and measured its mass at various points along the infalling trajectory, you'd make the same measurement regardless of where you are. Getting this right requires handing the black hole as part of the system.
Either you're thinking too hard about the subject or Minutephysics was wrong to make such a short video about a topic with so many variables without going super in-depth. But I usually perceive their objective as: let's get people 'curious' about physics without sounding like a textbook; albeit, that leaves room for error as physics is pretty complex and short videos don't always do it justice. So I will agree that mistakes were made by their focus on making the subject entertaining rather than being unarguable. It's hard to have it both ways.
I really think that there was a typo in the Chemical Reaction's section: I.e., [5e-10 (Released Energy in Grams) / 5e+3 (Cat’s Weight in Grams)] × 100 = 1e-11% (not 1e-9%); and it’d take (after removing the percentage) 1e13 (ten trillion, not ten billion) cats to power Norway with chemical reactions for a year. P.S. If one is to use the percentage’s perspective (i.e., in the Nuclear Reaction’s section, 150 cats were supposedly needed (which is 100/0.7 = 142.9 cats)), the Chemical Reaction’s section shall then be needing a hundred billion, also not ten billion, cats.
Except gas cloud G2 that amazingly went right through and past our super massive Schwarzschild Singularity in 2013 with no effect.... Riddle me that one, BatMan.
+ch .kuhn Ohh, I can riddle this. Astronomical object G2 was not a gas cloud but a binary pair of stars in an 300 year elliptical orbit around the black hole. The observed behaviour was not them crossing the event horizon but rather the two stars colliding with each other and merging together (with each other, not the black hole) at periapsis (closest approach to the object being orbited, in this case the black hole). Even if it had been gas, it didn't pass through the black hole, it passed (relatively) close by. It appears you've fallen victim of the old media cliché of publishing the lie on the front page, then burying the retraction on page 10.
I appreciate the first halfway cogent reply Ive received on this vid for being a skeptic of un-verifiable black hole theory, however your assertion Ive somehow been duped here is a bit rude and bordering on another ad hom attack...I'll give you the benifit of the doubt here... I did a quick google search to try and find something to substantiate your assertions.... Could not locate anything....Can you provide a citation or a link to your assertion?
Also...psydo-science by definition is a science that cannot be wrong....No matter how may times predictions are provably incorrect....Which is about a 100% clip for black hole theorist, there's always a reason why there was a 'miscalculation'....ALWAYS. I happy enough to say we have no idea whats there. We don't.
2:40 Now granted, we don't fall to the ground to create energy, but as a person from Norway, I can report that we get most of our electricity from stuff doing this; or rather water falling down through hydro-electric power plants.
I had no idea the event horizon would be further in in the spinning black hole. I thought the size depended on mass only and had wondered if it possibly was because space couldn't hold more information in that volume.
@@jaywu4804 well energy cannot be destroyed nor. created, only converted (I think) light requires energy, heating stuff also requires energy. That's why lamps require electricity
@@woahdude5553 I hope you are sarcastic, because if not you understood nothing. Mass is just a gathering of different energy forms. Energy cannot be destroyed nor created; you get the illusion that mass "creates" energy or can be "converted" into energy, but it cannot. To make it easyer let's compare each form of energy as a defined vegetable and mass as a salad. It feels as if the salad is its own thing, but it is not. The salad gets its properties from the veggies inside. Let's transpose what you are saying in the example: what you are saying is that you can make vegetables appear from thin air or magically transform all the salad into a melon. But the correct way to interprete it is to say that you pick some vegetables from the salad (different energy forms), and rearrange the atoms in the veggies into some other vegetable, thus noting is created and nothing is lost. The reverse applies.
Two things, 1) So in the future, humanity could theoretically cover it's power demands only through Black Hole Burrials, the most badass way to be burried. 2) This doesn't even account for if we figure out how to harness Hawking Radiation, then the numbers will probably go up.
Hawking radiation is not very hard to harness. The problem is that it is so stupidly low power that harnessing the fallen cat energy back would take trillions of years. And the bigger the blackhole the slower it takes to harness. But it is pretty good for the end of time projects when no star remains civilizations could still live on extremely low power regime for trillions of trillions of years. Though they will need to figure out how to reduce energy consumption of the whole civilization to the level of like a single lightbulb.

You're asking the right questions, my friend!
I _think_ yes, but asymptotically far into the future for any frame of reference further outwards than the cat's. So if you want to actually see the cat land, you have to throw yourself in at the latest with the cat, if not just ahead of the cat.

With a small enough black hole, you can convert 100% of the infalling mass to energy. Small ones are "hot" and have significant Hawking radiation. So you get one that's the right size to produce the power you want and then throw in mass periodically to keep it from getting smaller. If you stop feeding it, it shrinks, gets hotter and radiates faster and eventually blows up. But keeping it in balance is pretty easy if you are talking power needs along the lines of Norway or the world. Trickier if you want really gigantic power production from a smaller black hole.
That’s actually really smart.
*A N T I C A T*

You blinked?
We have normality!
So the question to the answer of life, the universe and everything might just be -
"What percentage of mass is converted into energy as it orbits a black hole which is spinning as such speed that its innermost possible orbit coincides with its event horizon?"
There is only one way to know how efficient an energy source is: How many cats will it take to power Norway for a year?
Even at 10 cats per Norway per year, that's awesome! And cats are a renewable energy source; so, we'd be set for at least a couple hundred million years!
We will call this unit of measurement, Cats per Norway per Year.

@@Alexander99602 Google Penrose process. You can literally extract energy from a black hole on the expense of its rotation. Basically, you'd have to throw a cat into the region called ergosphere (which is the region where things cannot stay stationary anymore) with the right amount of speed and in certain direction. End product is the cat (unfortunately to be more precise, a part of the cat) emerging out with more kinetic energy than she initially had.
@@dariobarisic3502 guess we found a good ideea how to gain energy... Too bad we can't use it for now

I wish my math teacher would explain things with examples like how to power Norway with cats instead of just boring stuff directly from the textbook that was made specifically to cover only the curriculum on the test at the end of the course, not made so we actually retain any of the information. I'm way more likely to remember this than some of the boring things in my algebra 2 class, and I probably don't even understand this very well compared to algebra 2 which is really easy. I'm so glad people make educational stuff on youtube.

There's an even better solution to this with rotating black holes. You can directly harvest the rotational energy of the black hole through superradiance of lasers. Surround it in a reflective surface - or more likely arrange wave guides in specific patterns, and superradiant scattering will dump huge amounts of energy into the laser drawn from the rotational energy of the black hole
Indeed, but cat is much funnier than lambda

PFFT THIS COMMENT HAS 42 LIKES. PERFECTION
GetYours this annoys me. You realise that the timestamp won't work because it sends you to the beginning of the second, and anyone who watches the video would know where it was so they can go look.
The first couple of minutes of this video are very good. I appreciate the good analogies which explain clearly how much of an object's mass is lost in a typical reaction. Unfortunately, the rest is almost completely wrong. This is because when an object falls into a black hole, the radiated energy comes from its gravitational potential energy, _not_ from its mass. The mass doesn't change in such a process. The main mistake being made here is to ignore the black hole itself as a component in the reaction: there is indeed some conversion of "mass into energy", but it's not the mass of the cat, but the mass of the _combined black hole and cat system._ For a rotating black hole, you're actually extracting energy from the black hole's rotation (see: Penrose process).
I at first thought that this video would make the case that black holes convert mass to energy completely because they eventually evaporate if you wait a _really_ long time. This would be a better case to make in this context, though you also have to take into account the thermodynamic efficiency in extracting such energy (Hawking radiation is thermal).
I thought the same. Of course you could argue that since energy is mass, the radiated energy comes from the object's mass (not sure how to view potential energy, though). However, in this case, the video's topic of "conversion" doesn't make any sense, really. And yeah, hawking radiation hasn't been mentioned for some reason.
If I understand you correctly, I wouldn't say "the rest is almost completely wrong". I think the video is just focusing on the conversion efficiency and not getting into the details of how this type of mass/energy conversion is somewhat different than the previous examples they cite. Yes you're right: In this case the mass is being converted to energy by an "outside" assist (the black hole), but there is still a mass-to-energy conversion happening in the overall process.
The language of "mass to energy conversion" is a bit sketchy at the best of times because, strictly speaking, it's category error. Nothing gets "converted" into energy because energy is conserved, rather, it's energy that used to be associated with rest mass that gets converted to kinetic energy of some particles or fields, typically photons. Here it is much worse because it gives the impression that the body gets lighter as it falls down the black hole. On the contrary: if you went alongside the object and measured its mass at various points along the infalling trajectory, you'd make the same measurement regardless of where you are. Getting this right requires handing the black hole as part of the system.
Either you're thinking too hard about the subject or Minutephysics was wrong to make such a short video about a topic with so many variables without going super in-depth. But I usually perceive their objective as: let's get people 'curious' about physics without sounding like a textbook; albeit, that leaves room for error as physics is pretty complex and short videos don't always do it justice. So I will agree that mistakes were made by their focus on making the subject entertaining rather than being unarguable. It's hard to have it both ways.
It's a particular case , cats bend spacetime

No rway! It can't be!
B-b-but, weren't they supposed to be thrown around the black holes' event horizon? You're doing it wrong!
I really think that there was a typo in the Chemical Reaction's section:
I.e., [5e-10 (Released Energy in Grams) / 5e+3 (Cat’s Weight in Grams)] × 100 = 1e-11% (not 1e-9%); and it’d take (after removing the percentage) 1e13 (ten trillion, not ten billion) cats to power Norway with chemical reactions for a year.
P.S. If one is to use the percentage’s perspective (i.e., in the Nuclear Reaction’s section, 150 cats were supposedly needed (which is 100/0.7 = 142.9 cats)), the Chemical Reaction’s section shall then be needing a hundred billion, also not ten billion, cats.

+ch .kuhn
Ohh, I can riddle this. Astronomical object G2 was not a gas cloud but a binary pair of stars in an 300 year elliptical orbit around the black hole. The observed behaviour was not them crossing the event horizon but rather the two stars colliding with each other and merging together (with each other, not the black hole) at periapsis (closest approach to the object being orbited, in this case the black hole).
Even if it had been gas, it didn't pass through the black hole, it passed (relatively) close by.
It appears you've fallen victim of the old media cliché of publishing the lie on the front page, then burying the retraction on page 10.
I appreciate the first halfway cogent reply Ive received on this vid for being a skeptic of un-verifiable black hole theory, however your assertion Ive somehow been duped here is a bit rude and bordering on another ad hom attack...I'll give you the benifit of the doubt here...

@@MythOverseer energy can be destroyed and created..... how do you think anything in this video works?
@@woahdude5553 I hope you are sarcastic, because if not you understood nothing. Mass is just a gathering of different energy forms. Energy cannot be destroyed nor created; you get the illusion that mass "creates" energy or can be "converted" into energy, but it cannot.
To make it easyer let's compare each form of energy as a defined vegetable and mass as a salad. It feels as if the salad is its own thing, but it is not. The salad gets its properties from the veggies inside. Let's transpose what you are saying in the example: what you are saying is that you can make vegetables appear from thin air or magically transform all the salad into a melon. But the correct way to interprete it is to say that you pick some vegetables from the salad (different energy forms), and rearrange the atoms in the veggies into some other vegetable, thus noting is created and nothing is lost. The reverse applies.

2) This doesn't even account for if we figure out how to harness Hawking Radiation, then the numbers will probably go up.
Hawking radiation is not very hard to harness. The problem is that it is so stupidly low power that harnessing the fallen cat energy back would take trillions of years. And the bigger the blackhole the slower it takes to harness. But it is pretty good for the end of time projects when no star remains civilizations could still live on extremely low power regime for trillions of trillions of years. Though they will need to figure out how to reduce energy consumption of the whole civilization to the level of like a single lightbulb.
