This video is about how efficient various reactions are at converting mass to energy (as we know from the Einstein mass-energy equivalence of E=mc^2). Antimatter is very efficient but it is not naturally-occurring. Chemical reactions like fire or explosions are very inefficient. Nuclear fission and nuclear fusion are better, but not amazing on an absolute scale. Non-rotating black holes (Schwarzschild) and rotating (Kerr) are by far the most efficient, due to their accretion disks and very small radius of their innermost stable circular orbits.

C is universal constant. It just so happens to be the speed of light.
@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. 😅

Mistake in your calculations. Cats have 9 lives. So, you only need 1/9 of a cat to power Norway for a year.

This is the law of equivalent exchange
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.

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 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.

I'm guessing that the chemical energy released in reactions was itself stored as the mass of chemical bonds themselves, which when broken are converted into energy.
Endothermic reactions presumably result in more mass stored in the reactants, that mass coming from the ambient heat of the room

What is the mechanism? Where was this mass/energy relative to the EH before merger? I can't find discussions of this anywhere, not in scientific papers, internet presentations or UA-cam. Thanks.

The object I threw into the black hole is crashing into stuff as it orbits / spirals in... but the stuff around the black hole is also necessarily orbiting / spiraling in, too. So the crashing doesn't have as much oomph. It's not like my object is crashing into stationary stuff. I could throw it against the tide of the accretion disk-then there'd be more violent crashing-but that goes against the thing he was saying about rotating black holes.

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.

Assuming that we some day create a processes that can capture energy from matter, anti-matter annihilation and turn it into anti-matter con be done at more than 50% efficiency so long as we keep feeding in matter we sustain this cycle and use the energy not used to create more antimatter as profit to power things or create even more anti-matter. So long as this process is scalable you could in theory start from a single anti-quark (bit small, anti-hydrogen would be better) and keep feeding in mass and scaling your anti-matter production until you are producing sufficient power. This will obviously take a huge amount of mass, just a fun thought though.

@@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
Instructions unclear, powered Sweden instead
Awesome drawings 😁
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 UA-cam). 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.

is the loss of mass from the reaction of hydrogen and oxygen an actual quantity that was measured or a result of using E=mc^2 to backwards compute the mass from the change in enthalpy?
from my understanding, no mass is lost in a chemical reaction but rather chemical energy in the form of energy levels of electrons and chemical bonds is being converted to heat energy and vice versa
Another benefit of using neutron stars over black holes is that in principle you can build structures on their surface, within the photon sphere. This is significant because it means the energy is greatly blue shifted. So you actually can in principle break 100% efficiency. I don't know that you want to since the surface of a neutron star being bombarded with cats is going to be a very hellish place with high gravity and relativistic debris, but you could.
If we throw cats in black-hole do they land on their feet?
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.

You guys are right about black holes. They are made of the most efficient reaction in the universe. They are made of quark plasma. It is this plasma that is the reaction that is the point of E=mc2. This is the reaction that the matter in the cat would have to be broken down to in order to get maximum energy. Quark plasma uses the power between the quarks as opposed to the power between atoms like fusion. While fusion requires massive amounts of electricity to create, quark plasma, once shocked into existence, uses the dark matter of space as a catalyst as it flows through us causing gravity. Quark plasma is so broken down that the absolute zero dark matter of space actually deters it from reconnecting even though the dark matter is what eventually puts it back together. Dark matter is extremely pressurized electron neutrinos.
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.
DavidKlausen - I heard Norway was leading the way on the much more efficient and socially acceptable squirrel incineration.
Inchido what
They dont mainly make browncheese with goat milk
They mostly use normal cow milk

Me: There's No Rway a cat can produce so much energy!
My Cat: Yeah! just throw a dog.
Ress lol
Kenya not do the puns?
But they're so cozy and warm.
Actually there is an even better way to generate energy with a cat. Just stick a toast with jam at the back of the cat and throw it at some height.
My cat has 5Kg of anti energy. Therefor the net result would be zero.
4:38 Wasn't the event horizon of a rotating black hole squished at the poles, making it larger?
@2:31 mass should remain constant no? lost mass exists in the form of other particles(like oxidised compounds formed due to heat generated on its surface), heat is due to friction and other energy conversions(kinetic to heat)?
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?"
1 year later: Do not play with cats!
Or how about, “Don’t play with yourself!”
What do you mean by not playing with one's self? ;-)
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).
yes it is
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
I use a cat with buttered toast strapped to its back to levitate my flying car.
How many lives do politicians have? They seem to be rather weighty, so there's an energysource just waiting for us . . .
E = mc²: " I'm the most well known equation in he world "
1 + 1 = 2: "I'm about to end this mans whole carrier"
the problem from there is now converting the heat into a usable energy. so in reality through all these means you still need to go through one more set of efficiency, a steam turbine. So putting into practice the most efficient turbine (36 to 42%) combined with the most efficient black hole would still need at least 5.95 cats to power Norway for a year.
Instructions unclear. I threw a black hole into a cat to power Norway.
Well I threw Norway into a cat to power a black hole, totally normal.
@@ansh6370 I threw a black hole into Norway to power a cat.
This is the best comment string ever also I tried throwing a Norway into a cat to power a black hole but the cat just spit it up as a hair ball
Black hole threw me into cat to power Norway
Norway through a black hole into me to power cat

Someone who knows what Galaxy on Fire was? wew
@@Derpy-qg9hn pretty incredible, but me too! I found the campaign pretty fun back in the day, played through all of it on my Mac back in 2011
nega matter
Oh my, i love that game
I was gonna say that I feel bad for the cat that has to be chopped in half for this to work, but honestly, getting chopped in half is a much less painful way to die than being spaghettified in a black hole.
The guitar effect is so good
