Since I was a child and thought about going for science, this was one of the things that brought me to it, how can we take the most out of things?

[@Tletna]

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).

[@tahneethompson6012]

yes it is

[@BluesyBor]

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.

[@Ze_eT]

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

[@nicotti]

Depends, are you burning them, splitting/fusing them, or dropping them into black holes?

[@cbarnes2160]

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.

@@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.

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.

Nerd/⁠ᐠ⁠｡⁠ꞈ⁠｡⁠ᐟ⁠\

[@vacuumdiagrams652]

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).

[@mammutmkii7242]

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.

[@AaronSmith1]

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.

[@vacuumdiagrams652]

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.

[@MagnakayViolet]

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.

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.

Black holes can also release energy from mass just from inspiraling in the form of gravitational waves. GW150914 (the first and largest detection of gravitational waves by the LIGO collaboration) had initial black holes of 36 and 29 solar masses. The final black hole was 62 solar masses (with some error bars). Three solar masses worth of energy was radiated in the form of gravitational waves. For the purpose of this video that's ~5% efficiency, so not bad.

jerryf609 I thought you were going to mention cats 😅

[@krischan67]

To be precise, black holes produce so much energy from stuff falling into them because those 42% are the mass equivalent of the kinetic energy gained by it which can be turned into radiation e.g. by fricton. None of the rest mass of the object is converted to energy, assuming it doesn't undergo nuclear reactions in the process (which would not add much to it anyway, as said in the video) or get into an environment that is extreme enough to violate particle conservation laws. Hawking radiation violates particle conservation, for example. Another pretty efficient energy source involving black holes is to extract rotational energy from it. That can be achieved by sending stuff close to it, but not so close that it cannot escape anymore on its own, which can lead to that stuff ending up with a higher sum of kinetic plus potential energy than before... or perhaps it just works wirh photons which can end up witha higher frequency (aka more energy) than before, I'm not sure (there is a video about it somewhere on KZbin). That would be an almost limitless source of energy, as black holes can have stupendously huge amounts of it. For example, the supermassive black hole at M87 (the one we have a picture of) has a rotational energy of about the equivalent of 10 trillion supernova explosions IIRC... and a few people here might know about how huge just a single supernova is, from the following cite from what-if.xkcd.com/73/ "However big you think supernovae are, they're bigger than that. Here's a question to give you a sense of scale: Which of the following would be brighter, in terms of the amount of energy delivered to your retina: - A supernova, seen from as far away as the Sun is from the Earth, or - The detonation of a hydrogen bomb pressed against your eyeball? Applying the physicist rule of thumb suggests that the supernova is brighter. And indeed, it is ... by nine orders of magnitude." Just a single supernova is so huge that some astronomers use a separate energy term for it: The foe. It stands for "ten to the *F*ifty-*O*ne *E*rg" which is the order of magnitude of a supernova, in cgs units which are still common in astronomy.
