@O 99 Correct (that we're aware of, anyway). There are multiple universal constants, though. C, or the universal speed limit, is just the constant that is called for in this equation. We can change the constant. That just changes apples to oranges, so to speak. 😅
Hey, at least Schrodinger proposed putting just a vial of poison in his box to put the cat in a superposition of dead and alive. Einstein suggested a stick of dynamite. He then asked whether you really needed to open the box to learn whether the cat was alive or dead.
A paragraph describing galactic civilizations' main source of energy to be throwing cats into black holes is exactly something that would show up in Hitchhiker's Guide
Now it certainly makes sense! The real problem of everything is Energy and now we know how to make the most energy!! Throwing cats to rotating black holes, of course. The towels are to catch the cats, in case you're wondering.
I never seriously considered it before because it's totally made up, but the idea of Star Trek Romulans using an artificial black hole as a power source on board their spaceships makes a lot of sense after your explanation. Thanks!

Questn, actually, as a macroscopic object, we are 99% energy and 1% matter. The protons and neutrons in our atoms weigh more than the sum of their parts (being the quarks inside them). The quarks alone account for 1% of the mass of the hadron and the rest is energy coming from the kinetic energy of the quarks and the strong force interactions binding them together.
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. Once they found cats, they didn't know about their 9 lives, and threw a cat into a black hole to power their colony. After that, they were completely wiped out, but the solar-system was in the safe zone. You should thank cats for sparing such mere un-cute humans
Today: "Don't play with fire!" Later today: "Don't Play with nuclear fission!" Tomorrow: "Don't play with cold fusion!" 1 week from now: "Don't play with black holes!" 1 month later: "Don't play with antimatter!" Yesterday: "Don't play with anaerobic cellular respiration?"
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.
see, now making the energy isn't hard, but how would you actually harvest that energy? Solar panels? peltier chips? grabbing all the hot plasma and throwing it into a steam generator? perhaps more cats? that would a be a great video to watch. "how to get the energy from black hole accretion disks"

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
@@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 _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.
I read something before and it said the efficiency could reach almost 100% if you drop the object into a black hole very slowly to almost 0 speed. It was mind blowing.
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?"
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
Thank you, and that process doesn't consume any of the mass of the water, it only consumes the gravitational potential energy the water had. I fail to see how extracting energy from things falling toward black holes is any different. If you want to actually consume the mass of stuff falling into the black hole, drop it in and harvest the Hawking radiation as the black hole evaporates.
I think the point was that the energy conversion is more efficient. But, it is different because what you are really extracting is solar energy since the sun had to heat the water to get it up to the top of the hill in the first place. So, ultimately, that's nuclear power.
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.
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!
@@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.
Honest disclosure I don't even have a cat, I just have a dog. I just thought my cat thinks this is fake news was a perfect comment due to our current politics. Also for the record my dog did weigh in and he said squirrels are much more efficient fuel than even cats. But if I am honest he is a bit more than slightly biased.
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.
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.
The solution is to strap two cats back to back and drop them. Since the cat will always land on its feet the cats will hover in the air spinning rapidly. Now you just use that rotational energy to power Norway.

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.
Wow, Norway is powered by cats... I learned something today.
Cats are powerful :-D
DragonOfTheSkies: ohh, _powered_ by cats, not _governed_ by cats. Sorry, my mistake B-)
i think we are all powered by kitties. but kitties theirselves are powered by aliens, explaining their weird behaviour

see, now making the energy isn't hard, but how would you actually harvest that energy? Solar panels? peltier chips? grabbing all the hot plasma and throwing it into a steam generator? perhaps more cats? that would a be a great video to watch.

@@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.

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.
Top 10 Questions Science Can't Explain

No, no and no. Even if the cat have a spacesuit, the cat will be torn apart before it hits the black hole
I read something before and it said the efficiency could reach almost 100% if you drop the object into a black hole very slowly to almost 0 speed. It was mind blowing.
Time to drop everything, but slowly

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.
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?"
It seems Norway suffers a serious power shortage...

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
I think it’s called a Penrose Sphere, for anyone wondering - Kurzgesagt did a video on it also about the biggest bomb in the universe
After 4:58, for some reason, I feel like I know the meaning of life, the universe and everything.
I love how it was subtly suggested that Norway could meet their energy need for a year by burning 10 billion cats.
Andrew Clarke: It is a renewable energy source.
We will take it into consideration
Patrick Shelley 10 billion? Doesn't like very renewable for me
Algorythmis: First, it was a joke. Second, just because you can outpace a resources renewal rate doesn't mean it's not a renewable resource...
You understand that it would it take more energy for the cats to eat and breed then you would gain from burning them right?
I'm Norwegian, and I can confirm that we incinerate 10 billion cats each year to fuel our power grids.
Can confirm, but it's more like 7 billion.
Because they're fat cats.

I like the idea of sacreficing cats to the cosmos to get energy in return
2:42 Actually, falling to the ground is how we convert about 17% of all the electrical energy consumed on the Earth. It's called hydroelectricity.
Thank you, and that process doesn't consume any of the mass of the water, it only consumes the gravitational potential energy the water had. I fail to see how extracting energy from things falling toward black holes is any different.
If you want to actually consume the mass of stuff falling into the black hole, drop it in and harvest the Hawking radiation as the black hole evaporates.
I think the point was that the energy conversion is more efficient. But, it is different because what you are really extracting is solar energy since the sun had to heat the water to get it up to the top of the hill in the first place. So, ultimately, that's nuclear power.
It can fall longer with way higher speeds - and with that, way more radiation in all kinds is happening .. well all die from cancer tho
And if you really think about it, you can trace it all that back to the sun, so it's effectively nuclear fussion.
Pfhorrest that still is decreasing the mass-energy of water by the mass of a cat, relative to a fixed reference frame.
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.
"At that rate, you would need 150 cats to power Norway for a year. (Not bad)"

“You’d only need to throw 17 cats into a black hole to power Norway for a year” is just about one of the most cursed things I’ve ever heard.
Better than 3,4/1 000 000 000 cats needed to power Norway by burning them.
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.
in short: deleting a cat creates a gigantic amount of energy in order to balance the universe
Did you do it? yes. What did it cost? 2.5 cats per year.
@@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
@@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.

Frank Delgrosso Oh...ok. Good! I was kidding. Any man that owns only a cat isn’t a real man. Hence the quotations. I was being sarcastic.
Honest disclosure I don't even have a cat, I just have a dog. I just thought my cat thinks this is fake news was a perfect comment due to our current politics. Also for the record my dog did weigh in and he said squirrels are much more efficient fuel than even cats. But if I am honest he is a bit more than slightly biased.
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.

2:04 thank you for not adding the obligatory line of "Nothing can escape a black hole - NOT EVEN LIGHT"
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...

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.

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.

The solution is to strap two cats back to back and drop them. Since the cat will always land on its feet the cats will hover in the air spinning rapidly. Now you just use that rotational energy to power Norway.
