I think the ancient Greeks were probably thinking about the STATES of matter with their analogy. Earth - Solid Water - Liquid Air - Gas Fire - Light/Energy For their access of knowledge, that's actually pretty brilliant.
But ancient Indians long long ago, definitely before the Greeks told that there r 5 elements..the 5th one being Space..ie., Dark matter n Dark energy all put together. ..
but is there? I mean there must be something for there to be darkness, darkness is something right? We honestly have no idea what is "outside" of the expanding universe, just like we can't know what was before The Big Bang.
It expands into the space it occupies. If you can think of it as a sphere of boiling matter, bubbling away in space, what bubbles up from the inside rolls around itself back down into itself. So in essence its occupying an infinite space and it just expands and bends its way through itself into the space it occupies. That's how I imagine it anyway.
I would love to mention few things. According to Hindu ancient scriptures, there are 5 elements: the fifth one is SPACE. Way back in ancient India, a scholar, Kanaad, had given the idea of tiny particle or atoms as the basic unit of any material. However, besides the matter content, there is Zero, which was later added in number system by Aryabhatta, another ancient scholar. Intriguingly, today also in India, we worship Shiva, which (and not who) is indescribable and is present throughout, and Shakti (energy), which help shiva in creation. Somehow, Indians could not pursue the research work started by ancient scholars. Having said that, it is good that the knowledge is unfolding now.
you are so right. in fact indian scholars like aryabhatta figured out the distance between earth, moon and the sun way back in time. And scientists today have used certain instruments to figure out that the numbers they gave were actually right. And its so sad to see our people abandoning our culture and values in pursuit of fame.
@@ameesinghamazing3825 doing a little google search doesnt hurt your finger brother. while i value patriotism, but being blind about it is totally not ok. the man who first measured the distance between earth and mon was Aristarchus and he was born around 310 BCE, while Aryabhata was born in 476 CE. this is the fact everybody agrees on.
I'm afraid not aditya. You must take social factors into account on these names. Can you imagine a physicist from Boston saying "daaak aaaats" and confusing everybody? It just won't do!
Why not? It would be sooo epic seeing their faces on a oh serious conference that it could actually get away with it as an opening joke of sorts. It would be awesome o,0,o
"you're living at the right time to see our understanding explode" Yeah well, it would've been great if i was born a few thousand years later, when we can be out exploring all of this stuff that we can only now dream about...
because there are a lot of things to actually learn, and this is just science porn. learn quantum mechanics first, because string theory is pretty much an attempt to explain that.
+Hiba Mary okay so youre saying instead of teaching high schoolers about things they can actually experience and would be intuitive to them ( like basic chem in labs and newtonian physics) which they already find hard enough and is at least likely to be useful for them later in life, we should teach them theoretical hypotheses that require understanding of other theories that require understanding of some of the relatively newest and hardest to grasp laws of the universe (general relativity and quantum mechanics)?
its probably worth saying that physicists speculate that the reason quantum mechanics is not introduced into the high school curriculum is because the difficulty of making a visual model for it. There are a few, however it does not really express the subject without a fair amount of subjectivity. In the past we do introduce stuff like this into the school curriculum, like electro magnetism. Still, once this is in the school curriculum you would probably find THAT boring because it isn't as mystical.
Till school day I used to think there's only biggest thing in this universe "The universe" But then I got to know TED-Ed and then I came to know there something much more bigger than the universe.......awesome....thanks TED-Ed for telling us such great things🥰💖💖💖💖
When I try to think of how I live in the right time, and in the right place to witness and cotribute to all this beautiful train of thought, at some point, by brain starts to hurt. The idea that, of all the possible times and places I could have lived, destiny chose this time and place for me, is just too hard for me to grasp. That's where the whys start invading my mind, and refuse to let any becauses enter.
Your thought itself could be wrong that you live in the right time and right place. Why should there be a right time and right place. Why should you matter so much to yourself when you are just a drop in this ocean of limitless time that will exist long after you are gone
Light is an agent that lets you see some of the matter that exists. There must be other agents that let you see some other matter that exists. Perhaps that other agent is the key to another parallel universe.
The adjectives and adverbs TED Ed uses to describe such complex things and phenomena is just overwhelming. The idea of atom being elegant.The motion of galaxies being graceful.
What we cannot see , can exist. Science is based on OBSERVATION. Does this mean science is LIMITED by its own definition such that it excludes the part of nature that is not VISIBLE or OBSERVABLE? For this instance, what is not visible is observable.
We try to make it visible, for example, radio waves, we cannot see them, but we can see how it acts, the better question is, why science rellays on light?
Quantum PhyZ Of course scientists try to make things visible that are invisible. Other invisible stuff according to theory is Dark Matter and Energy. For these, they say what is invisible is still science. But when it comes to religion, why do they not try to make it visible?
Cosmo John Because of evidence. You need evidence, before doing anything else. They have evidence of dark matter and dark energy, due the expansion of the universe, becoming faster and faster. The anti-matter particles for example. Had been found, and some people say it can be included as part of dark matter. In the case of the religion, there isn't enough evidence to support it in terms of science, but this doesn't mean, there is scientists using science to prove religion. Actually one of the great scientists of the XX century, tried to use science to prove religion. And many scientists such as Einstein believed on God. Einstein was even claimed by many as "fanboy" for the religion he supported ( aka, jews, don't know nothing about religion names, or things like that ).
+Quantum PhyZ You are right, Religion lacks evidence. But what if i say God exists in the 6th dimension and science is essentially on the 4th dinension and thats why scientists cannot 'see' the evidence for God? string theory touches on the multidimensions upto 10th. so, how can we conclude god does not exist even though in our human dimension , there is no evidence of him?
Cosmo John The string theory, the quantum fold, etc. Multidimensional theory, consists in using multiple dimensions, to make the maths easier to deal with, and to remove the anomalies that it has. Those 10 dimensions that we created to explain what happens at that level, is to explain the actions and movements on the string case. It is no longer a spacial thing to use. We need to convert it to 10 dimensions, to see its movement and actions, with this said, if we saw god movement in one of those dimensions, it would had been seen. Maybe we will find evidence of God, but not until we define theories and laws, at quantum level, that quite precises and demonstrates how it works. So the search for God is still to far away to us.
To note: The classical greek elements weren't 'wrong'. They just weren't describing proper ELEMENTS. They were describing the four states of matter: Solid. Liquid. Gas. Plasma.
Similarly, he says they were "wrong" about atoms being indivisible because modern atoms arent They weren't talking about modern atoms and had no understanding of them. What we call atoms were only given the name long after the Greeks, that naming being wrong proves nothing about the idea of a base particle that can't be cut.
The universe is full of mystery and enigma, and the fact that scientist can openly admit when something is there but can't seem to explain it yet they know for sure it exist is a testament to all humanity and it's entirety.
Maybe dark matter is a part of the electromagnetic spectrum that's invisible to us? Further away from gamma rays, real far away. Idk, it's mind boggling

“As far as we know, you’re a member of the only species in the universe able even to begin to grasp its wonders.” Pretty bold assessment to assume humans are the only species capable of doing that, when the probability is almost 100% that there is an exact copy of you somewhere else in the universe.
its amazing that ,we human beings are so insignificant in this vast universe, but also significant enough to have minds that wants to explore the wonders of the galaxy.

"all the particles we know today are just different harmanics on the string"... Does anyone else think about "the Music of the Ainur" when they hear that?
+Nathan Schreffler you are wrong my friend go and check out the facts/read The Grad Design by Stephen my Bae Hawking. Hundreds have been found (and i think this was like 20 years ago) and billions in our galaxy alone are estimated to exist, nothing special in our universe, altough considering the 10^500 different universes M-Theory predicts and how extremely narrow the conditions for life is we could say we live ina pretty special universe haha :)....I personally belive the reason that we havn't yet found intelligent life like ours yet is a logical and simple one. All the evidence points towards an earth that is about 4,5 billion years, and all the evidence points towards an universe that's about 13,7 billion years. Considering we are carbon-based lifeforms and that carbon can only be created in the centre of stars when they die in a process called resonans, carbon can only have "entered" our solarsystem when a supernova exploded billions of years ago, and that supernova had to have existed/been born shortly after the big bang considering the amount of time it had to have lived b4 it died,i'd say its logical to assume we are one of the very first forms of very intelligent lifeforms in the universe considering the more or less 4 billion years it took from single celled bacteria>us. So I think your statement would be proven utterly wrong in another few billion years when (i hope) we got a PEACEFULL starwars like galaxy.
+Danny Brown Pretty sure he was referring to the fact that our planet is the only planet where we know life exists. Even though there are plenty of other planets that could harbor life, we don't know if they actually do.
we are the only planet on which we met the existing life. we are NOT the only planet we know with the conditions to support life & we are 10000000% sure that we are NOT the only planet with life on it. we are no special snowflake!
+Apokakryptische Landmine I don't think you know how percentages work. Forget that you have to many zeros, I'll assume you mean 100%. my first question is, how can you be that sure that life exists on other planets when we don't even know how life began on this planet? I assume you know that at one point this planet had no life. how can life come from no life? This is not, possible naturally, only supernaturally. That's why Jesus's resurrection is the ultimate proof that he was God's son. life coming from no life shows that God's must have had his hand in the resurrection. you say there is lots of life in the universe. Then my second question for you is, how did that life come about naturally, since at one point there was no life at all in the universe?
***** I don't have much time right now so I'll read the rest of your comment later and take time to formulate an answer. About the too many zeros: is this the first time ever you're confronted with an exaggeration or are you pretending to be an idiot?
Interesting but the ending caught me off gaurd. I'm positive we ,humans are not the only ones who have thoufht of this theory. The univerese is expanding greatly so you said so odds are there are "species" or "Aliens" etc with similar knowledge if not more advanced.
Combine: 1. cosmological constant 2. schrodinger solution 3. Planck E= h f= h n 4. n = number of superpositions And you get dark matter n^2 h^2 / ( 8 m L^2) = h n m = 0.3313 10^18 10^-34 = 0.3313 10^-16 kg ( all superpositions). 1 particle = 0.331 10^-16 / ( 0.4 10^18) = 0.828 10^-34 kg = 46 eV If you count only the positive wave function amplitudes: n = 10^9 then dark matter = WIMP m = 46 GeV
Why do they think dark matter is matter? All they know is that spacetime is too warped for the amount of visible matter. It is quite possible that matter is not the only thing that bends space time to created gravity. It is quite possibile something else is causing dimples in spacetime (creating gravity pockets) and matter just falls into them naturally. If that is the case then dark matter particles will never be found because dark matter are just "dimples" in spacetime where matter collects. If space is a fabric the dark energy would push space apart creating wrinkles and pockets on the surface of the fabric where matter would collect...more needs to known about space. Looking for a particle may be fruitless.
WyZe It was just not dimples in space because of which they came up with dark matter theory ! Perhaps listen to video carefully again....it was proved that Galaxy had more mass then the possibly could weigh ! So there must be another matter lying between them holding it together...! Thats why its Matter ! And also other spatial events which arent mentioned in this video like event of two galaxy colliding together but passes unharmed etc etc
Nice analysis. I totally agree with your line of thinking. Too much gravity is not necessarily missing matter. Gravity may imply the existence of mass and matter, but sometimes it doesn't - it is just too much warping of space-time. It is the very riddle of dark matter. Thank you.
@@Germanywithtripti101 We don't know if dark matter has mass. What we know is that space-time seems to be reacting as if there is more than just visual matter present. We are assuming, since we know matter bends space-time, that this must be occurring because of some invisible excess matter but what if matter as we know it is not the only thing that bends space-time? if space time is a "fabric" this may be a feature of space iteslf... I mean no one knows but its fun to think about
well when the greeks said earth fire wind and water they didn't mean it conventionally. Earth was everything solid in existance, wind was all the gas, fire was the heat that gets produced by various nuclear reactions, water was well a common source of life and the first thing you search in a planet before you can determine wether it has life or not plus the cooling factor of everything which creates solidity. So in a sense they weren't THAT far from the truth. I still believe there is much more to it though
What if the universe is still expanding because it isnt done accelerating yet? After an explosion there is a moment of acceleration. What if that moment isnt finished for the big bang. Im not a physicist so idk, but what if? lol
the big bang is a huge amount of energy being converted into pairs of matter and anti-matter, and since no more anti-matter is observed, there is no more energy feeding into the expansion of the universe
It could be logical, though not probable. If everything was still accelerating it would probably be spreading out. Dark matter keeps everything together and in place.
Gravity causes the vertices of cubic planets to collapse into a shape where every point on the surface is roughly the same distance away from the center, aka a sphere
Atom comes from the Greek word άτομο. It is a combination (ά-τομο) of a deductive "α" and the word "τέμνω" which means "divide", which literally translates to "undivided". We may named Hydrogen and oxygen ets as atoms, but they really are not atoms, since they can be further divided into smaller molecules.
This is a good video! and for all the people who make this about religion, please open up your mind and heart and Think more deeply about this. If you are wise enough, you'll find out that this concept does NOT contradict any religion's fundamentals. I am a muslim and I know for a fact that the Quran encourages us to explore the World and comtemplate everything around us.It's just beautiful!
i m ex-muslim and i can assure you that Koran is b.s 1. universe was made in 6 days 2. sun and moon orbits the earth 3.muhammad went to space on winged worse 4.sun rises and sets in muddy pool wikiislam.net/wiki/Scientific_Errors_in_the_Quran sorry but religion and science can not get along
Hanane Allali ...how about you try and open up your mind,instead ... at least for once in your life ? Religions are creations of primitive man ... and they only represent the failed attempts of those primitive people to explain how to world works. The quran is no different ... it's not a path to TRUTH but only a refuge for ignorant and gulible people that are, nevertheless, desperate to find certainty in a world governed by uncertainty.
all the video is saying is already in Vedas..... Greeks came to know these after a long time after Vedas.even now if we consider Vedas, they are still thousands of years advanced than the modern day science.
So if the universe is accelerating outwards then eventually it will reach the speed of light right? So then what happens if there's people still alive on a planet somewhere and they simply jump with the direction of the universe? Technically they would break light-speed, so... yeah. Anyone care to prove me wrong? Please?
Well... Mass cannot reach the speed of light. In order to gain speed, more and more energy is needed. There will be a point in which there won't be enough energy to make mass travel faster, so it has a limit, and that limit is far away from nearing lightspeed.
Nothing travels faster than light THROUGH space, space itself can travel as fast as it wants and yes eventually the edges of the universe would be moving faster than the speed of light but that is completely possible because when the person jumps they're moving slow through space, it's the space itself that's moving at light speed
Johndoe717 There is something faster than the speed of light its called dark energy...but as you said yeah nothing is faster than the speed of light because dark energy is beyond human comprehension..but we might not know it will be discovered and defined
i fear if scientist know how to control dark matter, then they will control dark force. soon our scientist will become dart vader and turn to dark side
0:55 5th Century BC. Come on! Indial religious texts that have been dated back to 1200 BC already had the idea of the ATOM and called them PARAMAANU (परमाणु). Will the world ever recognise the contribution of the Indians?
good question, i dont know the answer but i will guess for fun and say they meant you can sense gasses but you cant sense dark matter or dark energy. i would think they can see the gas atoms in some form or shape
We have tools to interact to gases ...but dark matter and energy might be out of our human capabilities to interact with ...just like the 4th dimension...
Continue. . . In a gravity based universe you run into anomalies like stars traveling too fast on the outskirts of galaxies. To correct this anomaly cosmologist just created out of thin air this infamous Dark Matter. Just like religion you can't see or detect it but trust us it's there. We are a relatively young civilization, there is much to be learned.
Dark matter cannot only correctly predict the rotational curves of galaxies, it also forms gravity lenses that can be directly observed. In the collisions of galaxies it is even possible to observe galaxies without dark matter and dark matter that does not form the gravity well of a galaxy. Furthermore: the large scale structure of the universe and the amount of anisotropy in the cosmological microwave background (and the distribution of inhomogeneities in it) are by far best explained by dark matter. The only reason why someone would believe that science just assumes something to be true could be, because that person does not have the first clue about it. If you have a scientific idea and publish it, you can be damn sure that everybody will be trying to disprove it. And if you cannot provide any proper evidence, you are done for. Sorry dude, I think you are mixing up your version of science with the one that is actually praticed in reality.
It was Indians not Greek who first talked about 5 basic elements of life (panch tatv) and again it was India which gave the first concept of Atoms(paramanu) and molecules(Anu). Our Vedic literature explains these phenomenons well before Greeks would have ever imagined about it. The western scientific philosophy usually starts from greeks however, the origin of all initial curiosity over the universe was India.
I love that the one thing we know is that we don't know it all
yeah!

@@ameesinghamazing3825 doing a little google search doesnt hurt your finger brother. while i value patriotism, but being blind about it is totally not ok. the man who first measured the distance between earth and mon was Aristarchus and he was born around 310 BCE, while Aryabhata was born in 476 CE. this is the fact everybody agrees on.

Why didn't we study all this in high school?!! X-(
+Canned Snacks I can't see them be
because there are a lot of things to actually learn, and this is just science porn. learn quantum mechanics first, because string theory is pretty much an attempt to explain that.
+Hiba Mary okay so youre saying instead of teaching high schoolers about things they can actually experience and would be intuitive to them ( like basic chem in labs and newtonian physics) which they already find hard enough and is at least likely to be useful for them later in life, we should teach them theoretical hypotheses that require understanding of other theories that require understanding of some of the relatively newest and hardest to grasp laws of the universe (general relativity and quantum mechanics)?
its probably worth saying that physicists speculate that the reason quantum mechanics is not introduced into the high school curriculum is because the difficulty of making a visual model for it. There are a few, however it does not really express the subject without a fair amount of subjectivity.
In the past we do introduce stuff like this into the school curriculum, like electro magnetism. Still, once this is in the school curriculum you would probably find THAT boring because it isn't as mystical.

When I try to think of how I live in the right time, and in the right place to witness and cotribute to all this beautiful train of thought, at some point, by brain starts to hurt. The idea that, of all the possible times and places I could have lived, destiny chose this time and place for me, is just too hard for me to grasp. That's where the whys start invading my mind, and refuse to let any becauses enter.
Your thought itself could be wrong that you live in the right time and right place. Why should there be a right time and right place. Why should you matter so much to yourself when you are just a drop in this ocean of limitless time that will exist long after you are gone

Light is an agent that lets you see some of the matter that exists. There must be other agents that let you see some other matter that exists. Perhaps that other agent is the key to another parallel universe.
TopTribute Bands yeah
+Andrew Gunner I mean, we can technically see dark matter with gravity
we can't see it, we can only assume it exists.
+Andrew Gunner
I can't see gravity either but I am pretty sure it exists.
Henry School gravity is not matter.
When studying dark matter/energy I always get super excited, but get a little depressed at the same time.
The adjectives and adverbs TED Ed uses to describe such complex things and phenomena is just overwhelming. The idea of atom being elegant.The motion of galaxies being graceful.
u r too much into grammar, man!
Love it. Elegant and easy-to-grasp explanation.
What we cannot see , can exist. Science is based on OBSERVATION. Does this mean science is LIMITED by its own definition such that it excludes the part of nature that is not VISIBLE or OBSERVABLE? For this instance, what is not visible is observable.
We try to make it visible, for example, radio waves, we cannot see them, but we can see how it acts, the better question is, why science rellays on light?
Quantum PhyZ
Of course scientists try to make things visible that are invisible. Other invisible stuff according to theory is Dark Matter and Energy. For these, they say what is invisible is still science.
But when it comes to religion, why do they not try to make it visible?
Cosmo John Because of evidence. You need evidence, before doing anything else. They have evidence of dark matter and dark energy, due the expansion of the universe, becoming faster and faster. The anti-matter particles for example. Had been found, and some people say it can be included as part of dark matter. In the case of the religion, there isn't enough evidence to support it in terms of science, but this doesn't mean, there is scientists using science to prove religion. Actually one of the great scientists of the XX century, tried to use science to prove religion. And many scientists such as Einstein believed on God. Einstein was even claimed by many as "fanboy" for the religion he supported ( aka, jews, don't know nothing about religion names, or things like that ).
+Quantum PhyZ You are right, Religion lacks evidence. But what if i say God exists in the 6th dimension and science is essentially on the 4th dinension and thats why scientists cannot 'see' the evidence for God? string theory touches on the multidimensions upto 10th. so, how can we conclude god does not exist even though in our human dimension , there is no evidence of him?
Cosmo John The string theory, the quantum fold, etc. Multidimensional theory, consists in using multiple dimensions, to make the maths easier to deal with, and to remove the anomalies that it has. Those 10 dimensions that we created to explain what happens at that level, is to explain the actions and movements on the string case. It is no longer a spacial thing to use. We need to convert it to 10 dimensions, to see its movement and actions, with this said, if we saw god movement in one of those dimensions, it would had been seen. Maybe we will find evidence of God, but not until we define theories and laws, at quantum level, that quite precises and demonstrates how it works. So the search for God is still to far away to us.
I love how the animation shows atoms as a nuclei with a shifting electron cloud. That's the way !
Only the cloud is grossly undersized compared to the nucleus.

To note: The classical greek elements weren't 'wrong'.
They just weren't describing proper ELEMENTS.
They were describing the four states of matter:
Solid. Liquid. Gas. Plasma.
shepard1707 There is also the 5th important element which is Sex.
Similarly, he says they were "wrong" about atoms being indivisible because modern atoms arent They weren't talking about modern atoms and had no understanding of them. What we call atoms were only given the name long after the Greeks, that naming being wrong proves nothing about the idea of a base particle that can't be cut.
The universe is full of mystery and enigma, and the fact that scientist can openly admit when something is there but can't seem to explain it yet they know for sure it exist is a testament to all humanity and it's entirety.

*The Dark Universe, made of Dark Matter and Dark Energy*

“As far as we know, you’re a member of the only species in the universe able even to begin to grasp its wonders.”
Pretty bold assessment to assume humans are the only species capable of doing that, when the probability is almost 100% that there is an exact copy of you somewhere else in the universe.
As far as we know...
its amazing that ,we human beings are so insignificant in this vast universe, but also significant enough to have minds that wants to explore the wonders of the galaxy.
“Does all this make you feel small?”

We are the universe admiring itself, it’s so beautiful and technically we came from it, that it needed to realise how beautiful it was
That was phenomenal! The ending gave me incredible goosebumps!

Thank u.
I believe more and more there is no such thing as the physical world only. Science will never go through that barrier.
I’m studying for my astronomy final right now and having fun wow this is new.
We're on an ordinary planet? How about the only planet that supports life a far as we know. Send pretty special to me.
+Nathan Schreffler you are wrong my friend go and check out the facts/read The Grad Design by Stephen my Bae Hawking. Hundreds have been found (and i think this was like 20 years ago) and billions in our galaxy alone are estimated to exist, nothing special in our universe, altough considering the 10^500 different universes M-Theory predicts and how extremely narrow the conditions for life is we could say we live ina pretty special universe haha :)....I personally belive the reason that we havn't yet found intelligent life like ours yet is a logical and simple one. All the evidence points towards an earth that is about 4,5 billion years, and all the evidence points towards an universe that's about 13,7 billion years. Considering we are carbon-based lifeforms and that carbon can only be created in the centre of stars when they die in a process called resonans, carbon can only have "entered" our solarsystem when a supernova exploded billions of years ago, and that supernova had to have existed/been born shortly after the big bang considering the amount of time it had to have lived b4 it died,i'd say its logical to assume we are one of the very first forms of very intelligent lifeforms in the universe considering the more or less 4 billion years it took from single celled bacteria>us. So I think your statement would be proven utterly wrong in another few billion years when (i hope) we got a PEACEFULL starwars like galaxy.
+Danny Brown Pretty sure he was referring to the fact that our planet is the only planet where we know life exists. Even though there are plenty of other planets that could harbor life, we don't know if they actually do.
we are the only planet on which we met the existing life. we are NOT the only planet we know with the conditions to support life & we are 10000000% sure that we are NOT the only planet with life on it. we are no special snowflake!
+Apokakryptische Landmine I don't think you know how percentages work. Forget that you have to many zeros, I'll assume you mean 100%. my first question is, how can you be that sure that life exists on other planets when we don't even know how life began on this planet? I assume you know that at one point this planet had no life. how can life come from no life? This is not, possible naturally, only supernaturally. That's why Jesus's resurrection is the ultimate proof that he was God's son. life coming from no life shows that God's must have had his hand in the resurrection. you say there is lots of life in the universe. Then my second question for you is, how did that life come about naturally, since at one point there was no life at all in the universe?
***** I don't have much time right now so I'll read the rest of your comment later and take time to formulate an answer. About the too many zeros: is this the first time ever you're confronted with an exaggeration or are you pretending to be an idiot?
Interesting but the ending caught me off gaurd. I'm positive we ,humans are not the only ones who have thoufht of this theory. The univerese is expanding greatly so you said so odds are there are "species" or "Aliens" etc with similar knowledge if not more advanced.
I feel like I’m living in a time when scientists thought the earth was flat for where we are in space science
TED eds videos are my 5 mins of escape from my messed up life.
Combine:
1. cosmological constant
2. schrodinger solution
3. Planck E= h f= h n
4. n = number of superpositions
And you get dark matter
n^2 h^2 / ( 8 m L^2) = h n
m = 0.3313 10^18 10^-34 = 0.3313 10^-16 kg ( all superpositions).
1 particle = 0.331 10^-16 / ( 0.4 10^18) = 0.828 10^-34 kg = 46 eV
If you count only the positive wave function amplitudes: n = 10^9
then dark matter = WIMP
m = 46 GeV
Law of Attraction overload!!

The day we understand dark energy and how it affects light time travel will be a walk in the park
Schools: meh lets still say mitochandria is the powerhouse of the cell
Why do they think dark matter is matter? All they know is that spacetime is too warped for the amount of visible matter. It is quite possible that matter is not the only thing that bends space time to created gravity. It is quite possibile something else is causing dimples in spacetime (creating gravity pockets) and matter just falls into them naturally. If that is the case then dark matter particles will never be found because dark matter are just "dimples" in spacetime where matter collects. If space is a fabric the dark energy would push space apart creating wrinkles and pockets on the surface of the fabric where matter would collect...more needs to known about space. Looking for a particle may be fruitless.
WyZe because it has mass....anything has mass is matter
WyZe It was just not dimples in space because of which they came up with dark matter theory ! Perhaps listen to video carefully again....it was proved that Galaxy had more mass then the possibly could weigh ! So there must be another matter lying between them holding it together...! Thats why its Matter !
And also other spatial events which arent mentioned in this video like event of two galaxy colliding together but passes unharmed etc etc
Nice analysis. I totally agree with your line of thinking. Too much gravity is not necessarily missing matter. Gravity may imply the existence of mass and matter, but sometimes it doesn't - it is just too much warping of space-time. It is the very riddle of dark matter. Thank you.
@@Germanywithtripti101 We don't know if dark matter has mass. What we know is that space-time seems to be reacting as if there is more than just visual matter present. We are assuming, since we know matter bends space-time, that this must be occurring because of some invisible excess matter but what if matter as we know it is not the only thing that bends space-time? if space time is a "fabric" this may be a feature of space iteslf... I mean no one knows but its fun to think about
@@STAYYZ No we are not assuming, Dark Matter mass is scientifically proven. Go and search more.
this video is so ahead of its time it’s unreal
Let's take a minute to appreciate this narrators voice, timing and articulation damn
3:24 i can see fried chickens, so many of them.
well when the greeks said earth fire wind and water they didn't mean it conventionally. Earth was everything solid in existance, wind was all the gas, fire was the heat that gets produced by various nuclear reactions, water was well a common source of life and the first thing you search in a planet before you can determine wether it has life or not plus the cooling factor of everything which creates solidity. So in a sense they weren't THAT far from the truth. I still believe there is much more to it though
0:38 Dry like my jokes...
Hahaha get it?
1:24 there, there... That's how you really represent an atom. Great work. Most of videos show it as a planetary model.
I'm not a scientist but the best part of this video for me was 4:42 when I realised he's about to talk about String Theory.
What if the universe is still expanding because it isnt done accelerating yet? After an explosion there is a moment of acceleration. What if that moment isnt finished for the big bang. Im not a physicist so idk, but what if? lol
the big bang is a huge amount of energy being converted into pairs of matter and anti-matter, and since no more anti-matter is observed, there is no more energy feeding into the expansion of the universe
It could be logical, though not probable. If everything was still accelerating it would probably be spreading out. Dark matter keeps everything together and in place.

Atom comes from the Greek word άτομο. It is a combination (ά-τομο) of a deductive "α" and the word "τέμνω" which means "divide", which literally translates to "undivided". We may named Hydrogen and oxygen ets as atoms, but they really are not atoms, since they can be further divided into smaller molecules.

Religions are creations of primitive man ... and they only represent the failed attempts of those primitive people to explain how to world works.

Five basic elements...from ancient india
So if the universe is accelerating outwards then eventually it will reach the speed of light right? So then what happens if there's people still alive on a planet somewhere and they simply jump with the direction of the universe? Technically they would break light-speed, so... yeah. Anyone care to prove me wrong? Please?
Well... Mass cannot reach the speed of light.
In order to gain speed, more and more energy is needed. There will be a point in which there won't be enough energy to make mass travel faster, so it has a limit, and that limit is far away from nearing lightspeed.
Aarón Ramses Flores López k thnx
Aarón Ramses Flores López there are several items that could break the light barrier. Which is way faster than the speed of light.
Nothing travels faster than light THROUGH space, space itself can travel as fast as it wants and yes eventually the edges of the universe would be moving faster than the speed of light but that is completely possible because when the person jumps they're moving slow through space, it's the space itself that's moving at light speed
Johndoe717 There is something faster than the speed of light its called dark energy...but as you said yeah nothing is faster than the speed of light because dark energy is beyond human comprehension..but we might not know it will be discovered and defined
i fear if scientist know how to control dark matter, then they will control dark force. soon our scientist will become dart vader and turn to dark side

Continue. . .
In a gravity based universe you run into anomalies like stars traveling too fast on the outskirts of galaxies. To correct this anomaly cosmologist just created out of thin air this infamous Dark Matter. Just like religion you can't see or detect it but trust us it's there. We are a relatively young civilization, there is much to be learned.
Dark matter cannot only correctly predict the rotational curves of galaxies, it also forms gravity lenses that can be directly observed. In the collisions of galaxies it is even possible to observe galaxies without dark matter and dark matter that does not form the gravity well of a galaxy. Furthermore: the large scale structure of the universe and the amount of anisotropy in the cosmological microwave background (and the distribution of inhomogeneities in it) are by far best explained by dark matter. The only reason why someone would believe that science just assumes something to be true could be, because that person does not have the first clue about it. If you have a scientific idea and publish it, you can be damn sure that everybody will be trying to disprove it. And if you cannot provide any proper evidence, you are done for. Sorry dude, I think you are mixing up your version of science with the one that is actually praticed in reality.

It was Indians not Greek who first talked about 5 basic elements of life (panch tatv) and again it was India which gave the first concept of Atoms(paramanu) and molecules(Anu). Our Vedic literature explains these phenomenons well before Greeks would have ever imagined about it. The western scientific philosophy usually starts from greeks however, the origin of all initial curiosity over the universe was India.
