Whoever came up with the title of this video needs a raise.
Fool🤣
It's a physics-nerd joke. Regardless of the topic, I would have said, "Why dark energy didn't matter at the moment of the Big Bang."
😂😂 clever pun
must be very bright

This video is AMAZING! That’s why I love the Economist, such a broad and amazing variety of science and technology beyond politics and economics. I wish they had made this video an hour! Excellent!!!
holy fkn shill-bot Batman!
👍
What? This was so dumbed-down! I presume, by your enthusiasm, that it made you think you understood something about black holes? If so, I am actually happy for you - but the fact is, you can't understand anything meaningful about advanced physics without studying it. A youtube video explaining it to you in baby-talk is just conning you into some Dunning Kruger.
So, what does "The Economist" suggest? Should we invest in black holes?
No, it’ll be a black hole for your money.
Yes, your time horizon need to be infinite though
Thanks to "The Economist" for educating us through such kinda videos
Right? That was my first thought too XD
Not the channel i’d expect this from lol
Indeed, thank you!
For some reason people don't know that Einstein repeatedly said that singularities are not possible. In the 1939 journal "Annals of Mathematics" he wrote "The essential result of this investigation is a clear understanding as to why the "Schwarzchild singularities" (Schwarzchild was the first to raise the issue of General relativity predicting singularities) do not exist in physical reality. Although the theory given here treats only clusters whose particles move along circular paths it does seem to be subject to reasonable doubt that more general cases will have analogous results. The "Schwarzchild singularities" do not appear for the reason that matter cannot be concentrated arbitrarily. And this is due to the fact that otherwise the constituting particles would reach the velocity of light."
General relativity does not predict singularities when you factor in dilation. If you look at a common relativity graph with velocity on the horizontal line and dilation on the vertical, the phenomenon is clear, even mass that exists at 75% light speed is partially dilated.
There is no place in the universe where mass is more concentrated than at the center of a galaxy. 99.8% of the mass in our solar system is in the sun. 99.9% of the mass in an atom is in the nucleus. If these norms are true for galaxies than we can infer that there is 100's of trillions of solar masses at the center of common spiral galaxies. There is no way to know through observation there is far too much interference, dilation and gravitational lensing. High mass means high momentum. If we attribute a radius to these numbers than we can calculate that relativistic velocities exist in these regions.
The mass at the center of our own galaxy is dilated. In some sublime way that mass is all around us because as the graph shows we are still connected to it.
The greatest mystery in science is the abnormally high rotation rates of stars in spiral galaxies (the reason for the theory of dark matter). It was recently discovered that low mass galaxies (like NGC 1052-DF2) have normal star rotation rates. This is what relativity would predict because there is an insufficient quantity of mass to achieve relativistic velocities. This is virtual proof that dilation is the governing phenomenon at galactic centers.
A simple way to prove this would be to calculate the star rotation rates of a large number of galaxies. This would show that all the medium and high mass galaxies would have star rotation rates that defy the known laws of physics and all the low mass galaxies would have normal star rotation rates. Some galaxies can appear to be low mass but can have high mass at the center.
WOW that was some nice writing there I had to pause the video, I actually enjoyed it more .Thanks man !!!🙋🙋🙋🙋
@@IrelandsTrueKing Thanks
@@shawns0762 after reading what you've wrote, I think they wrongly named it black ⚫ hole, I think it's a very important body in universe, something like the "recycling" From matter become energy and to keep galaxy moving and recycled, also always actively release radiation
@@Cleeon The shape of a galaxy is common in nature. From atoms to our solar system, the overwhelming majority of the mass is in the center. The same must be true for galaxies. Where there is mass there is energy. The night sky should be lit up from the galactic center but it isn't.
The modern explanation for this is because gravitational forces there are so strong that not even light can escape, even though the mass of the photon is zero. Einstein's answer would be because the mass there is dilated relative to an Earthbound observer.
This was the accepted explanation until television and movies popularized black holes in the 1960's. Belief in them gradually came to be despite the fact that Einstein said that they cannot exist and there was no evidence.
The modern idea that there is some way to take a "picture" of the galactic center is absurd. The interference alone, dilation alone or gravitational lensing alone would make that virtually impossible. As per relativity, an observer would have to exist at or near it's momentum.
"Why they matter"
I see what you did there
Black holes matter
Interesting, informative and relatable - well done
Brilliant! Complex information distilled very well. Only thing is that sometimes the narrator's voice was muffled when the background sound was dropped in.
Economist is one of the best channel in yt at least to me......from science to politics their videos are amazing
Excellent piece loved it 😊
Forget blackholes. There's nothing important about them
Thank you for this very informative video .
Wow so impressed by this video! 👏
I’ve always like astronomy and the cosmos since the first grade way before getting into economics and finance as a young adult. This is probably why I like Star Wars a lot especially the astrography aspects of the series!
Excellent - clear and succinct
Always fascinating!
Gradually, life's becoming a sci fi movie for real
Thanks for this. Great stuff
Thank you for this
I would volunteer for NASA to be the first man to go through the black hole, live or die am prepared to further more our knowledge about the black holes .
Do you know how much knowledge we can learn from you going through a black hole? :Zero.
@@rocquecaceres9221 don't be so Pessimistic .
Bring me back a souvenir
Great video
Phenomenal video. Fascinating subject matter and complex ideas but outlined in a lucid and straightforward way that nonetheless isn't explicitly dumbed down.
Economist explaining us about BLACKHOLES. Cool!
Funny pun in the title : "matter" means not only "to be important" but it is also the material substance that constitutes the universe.
Lol why telling the other meaning of matter.
Also its a play on the black lives matter terrorist group
Another 'stellar' educational video from The Economist! By far the best, knowledge-packed and pleasant to watch videos out there..well done!
brilliant.
as usual
Because if there's a hole, there's a goal.
Now here’s a perfect answer to your titled question @TheEconomist
😖🥳
The blackhole is way too old I would love to try it if it was below 18 y-
If, as explained in the video, nothing can escape the gravitation field of a black hole, then what explains the gradual emission of radiation from the black hole?
I thinking about the same as you, even some energy jet launched from it
With great holes, comes great responsibility
Nice video
I love to learn about the universe.
Its incredible.❤
This is just insane!!
Nice to see some News that matters and isn’t “sensationalism”
As economists, we maybe have to concern "the black hole" on the earth, which is the human greed which has caused endless problems, conflicts and even devastating wars. The black hole mentioned in the program we may have nether been able to touch nor even explain it completely?
that black hole has also spewed inventions and scientific advancements, maybe for selfish purposes for nonetheless important. we are not perfect by any means, but we are at least not flawed enough that we can't make progress.
Interesting and informative. Plus uses clips from my favourite shows and movies 😂
We need to understand that being at the top of the pyramid of creation means that everything we do trickles down the structure, from top to bottom. When it reaches the bottom, the inanimate level of reality, from which everything grows, it changes it. If we ooze ill-will, it creates negative changes throughout the system, which manifest in increasingly extreme climatic and geological events.
In other words, when human relationships go out of balance, everything goes out of balance. When our relations become extreme, everything becomes extreme; when we become violent, everything becomes violent. Each summer, the ramifications of the linkage between our relations and our world become more extreme, until we acknowledge that everything that exists, exists in a connected, hierarchical system and that whoever is at the top determines the state of the rest of the system.
It is not as if previously, we were better people than we are today. It is simply that there were fewer people, and therefore fewer elements that exude ill will.
Also, relationships between people in the past were less toxic than they are today. While there are fewer wars today than ever, the levels of suspicion and alienation between people are skyrocketing, to the point where people can no longer trust their own family members. As a result, wars between countries are rarer than ever, but divorce rates, domestic violence, and violence in the community, are at an all-time high.
Even the internet, which we invented purportedly in order to connect people, is being used to abuse, deceive, and exploit people. The world-wide-web proves that everything we create, we use against others. When there is such a negative element in a system, and that element is at the top of the system, how can the entire system not go awry?
Therefore, if we want the weather to cool, the sea-level to drop, and the storms to subside, we must cool the fire and calm the storms between us. Mutual concern, mutual responsibility, or at least the knowledge that we are dependent on each other, are necessary in order to restore balance in our world at all levels, from the ground we walk on to the hatred in our hearts.
Interesting comment, thanks for posting
"Time and Tide wait for no man"... nature doesn't care about humans.
King Kanute famously ordered the tide to retreat....Unfortunately for Kanute the tide came in and drowned him.
Being kind to your friends doesn't stop a Category 5 hurricane from being unkind to you.
Take cover!
Extremely doubtful. The world and universe existed in chaotic and natural states long before humans came.
But let's talk about how they affect the political-economic situation in the world
wrong channel
Waddya think this is, The Economist??
Scary sound.
Nice
From The fact that we have a huge universe to the fact that we are perfectly made, makes me wonder why someone would say I was made by a Big Bang and not a designer
It's both. The Big Bang is the awakening to a world created by you the designer.
Dark matter Is the container of the information lost on the spaghettification process and this information further radiates outwards.....while gravity could be the electromagnetic copy of the matter giving off the gravity...Dark matter can be looked at as the wall upon which gravity is projected and manifested....very close to being in separable like an infinite inverting process from one state back to the next....the Hawkins radiation can very well be the new programmables that can be harnessed and channelled to create new states of matter ...much like metamorphosis....the Hawkins radiation demonstrates that black holes actually breaths...by taking in and giving out...there is inside the black hole a third state where matter goes to - to become radiation...this state I believe is the state of dark matter....to fully comprehend and index the components of dark matter I think we need to create devices that work on the whole light spectrum.....to fully understand the deeper mysteries of the universe....
donut on the moon: great album.
I like listening to the calm voices of The Economist
I vouch that Alok is saying everything true.
The singularity of a black hole is not infinitely small and dimensionless. It does have a size and shape: spherical and made of coherent energy.
They are not a native scientific publication, and are searching for views plus simple descriptions.
It's crucial to provide evidence indicating fuzzball nature of blackhole to validate string theory and the theory of quantum gravity or the AdS/CFT correspondence .
The evidence regarding the nature of blackhole is imprinted on its gravitational waves . We need to employ sensitive enough detectors to figure it out.
These scientists are so inquisitive and peaceful doing their research in the quest of knowing the unknown, not preaching or killing people in the name of Allah or Koran.
What about kkk
@@deepsavannah9723 Kkk is now a bunch of people getting together to scream at each other 😂😂😂
Is Black hole causing the inflation we are experiencing right now? Will also cause recession?
Curiouser still, it's a bit jarring to actually see someone you've only listened to on podcasts for such a long time. Hello, Alok Jha, I can finally put a face to that voice.
Gravity is actually relative absence of the energy conducting ether.
I want one!
Could Black Holes be how Galaxies end?
Because they allow for 8 million types of expansion of the universe. The 8 million types are further classified as shock wave expansion. Convoluted expansion. Spiral category. Surface extension. Spring effect expansion and symmetrical expansion. Usually symmetrical expansion is the most observable. Point expansion is critical for the creation of other universe types. Horse shoe expansion is critical in holding the different part universes.
No matter what I learn I simply cannot imagine black holes destroying that which enters, as described by science. That seems to be in opposition to the apparent order of the universe. Celestial bodies, specifically those that are not orbiting a star, contribute either “ingredients” or interactions that seemingly serve to organize and consolidate the universe.
If a black hole is sorta like a drainage hole, I want to be jettisoned into one immediately. I volunteer. Send me please. Lol
Have fun turning into spaghetti lol
Didn’t Penington recently solve the information paradox?
Where does the matter go? It is simple, there is no matter left, the matter become energy, it is that simple. A ray of energetic light! That lights is scattered across the universe.
If the Economist knows as much about finance as it appears to about black holes, then we all may as well subscribe to the Beano.
I think Blackhole is kind of gravity overflow as the only way to leak the secret of this universe.
Black hole looks like the end but also the beginning of a galaxy, looks like all galaxies have the same shape like they have stopped spinning around like a dead block hole
Blackholes are gateways to different universes.
Sand consists of hard, cubic, crystalline particles if you look at sand one piece at the time. But in bulk, sand is soft and squishy and moves like a fluid. There is no specific dividing point between sand as hard particles and sand as a fluid. So what's the big deal with the dichotomy between GR and QM?
Black Hole is a Wonderful Matter ✨
black holes are the glue that hold everything together, like a spoke of the wheel and in this case a galaxy and whatnot.
All holes matter
Black holes hold galaxys to its center - similar to Sun holds our planetry system to their respective orbits
Can not be infinite density for physics we know because would be limited by Plank length
But does our physics still hold there ?
Balancing

Galaxies

Possible
I thought my mom just traveled through black hole to another parallel universe. Hopefully she is doing well there.
maybe universes are like water drops, expanding out till theyre gone and then eventually falling into water again
Yush
Why we didn't point out James web telescope towards the center of our galaxy to take a clear picture of it's black hole?
Seems like destruction and transformation to frequencies
Incorrect animation of the event horizon. It's not some ring around the black hole, it is the "black surface" of the hole. Where nothing, not even light escapes once crossed.
Space is the desktop, Earth is a program, we are NPCs, and black holes are the recycle bin to keep the desktop clean, this is a simulation. When you don't know the answers, just make them up, it's fun.
Best comment ever😂
Maybe the only way to leak the secret of the black holes, is the economists in the stockmarkets.
Sound in universe?
Are all galaxies rotating around black holes?
Mate might be possible that the blackhole which is in the middle our our galaxy is causing out galaxy orbiting around itself
Not to be "that guy" but doesnt light move about 1 million times faster than sound? So theoretically what we are hearing from the area is millions of years older than what we are seeing from there if done at the same time.....am I wrong with this thought process? if so please enlighten me on how....
And I have another theory for black holes that's is part of brain univeristy and we live in organism have brain so when we experiment thats can conect and we can think more more and many ideas to creativity and make theory.
👏👏👏

I relate to this on a spiritual level, I won’t explain why
You feel it in your stomach?
Do you believe in horoscopes lol
Drain holes of the universe.
They are a wormhole to quickly travel from one point to another point of space.
They bend space.
source: trust me, bro
Economic blackhole
The particle exist and not exist at the same time.
The Ancient Egyptians knew about them already
MORE...
Black holes and space are black and do unique things to light I feel they are both intrinsically related.
It’s clear where the mass of matter goes. But the big question is where the information of the matter goes. This is particles quantum numbers like quark flavours, lepton number, baryon number , quantum spin …. These are bits of information that could be lost in a black hole, which we call the “information paradox”.
They aren't lost.
Einstein believed nature would not allow blackholes.
Galaxies

Panoroma
My takeaway is to max out my gold and platinum credit cards before leaving planet Earth
Om
Today I woke up thinking 🤔 black hole are the only thing we in the the 3er dimension can see or feel from the 4th dimension. What u guys think...
No
They are an important aspect in establishing the global 21st century religion.
Hmmmm 🤔
Black hole sound like a lion roaring
We are humans ,we want to find out more about black holes , because we have intelligence.
