How vast is this universe? Where exactly did we and you come from?
Are we alone in this entire universe?
Or is there any other creature here, perhaps something like a sorcerer?
After such tremendous progress in science, how well do we really know this cosmos?
What secret is buried in the Aver Expanding Universe?
Today, in this video, we will try to find answers to these curiosity-filled questions.
Sometimes life's dramas seem so huge.
The flight was missed, a fight broke out, they failed in Exim.
It feels as if the entire world has turned upside down.
But when we zoom out, we see that this entire drama
A plant named Aarth, which is about the size of a small blood clot
And she is floating in that vast universe.
They talk in such a way as Carl Sagan does in his book Cosmos.
Things that force you to think
As Carl Sagan said, the universe is so vast
that even imagining it is difficult
And this is precisely why scientists have sought to harness it.
A single unit has been extracted, called a "laiter."
The distance that light travels in one year
Light is the fastest thing in the world.
It travels three hundred thousand kilometers in just one second.
Yes, three hundred thousand, that is, within one second.
It can spin around with this world.
How far do you think this light travels in a whole year?
I'll tell you ten trillion kilometers
When astronomers say that a star is ten light-years away from us
This means that the light coming from this star
It takes ten years to reach us.
Whenever we see him, we don't consider him in the presidency.
They are looking at his past.
That star looks ten years older than us.
The fun here doesn't end—it's just beginning.
And as for these stars, are they really stars or not?
There are approximately one billion galaxies.
And each galaxy contains approximately a hundred billion stars and plants.
They are ten power twenty-two plants.
You add twenty zeros after a single digit.
An inheritance is also a plant among so many plants.
That's precisely why Karl Seeman says that when you feel like brother
The whole world should revolve around my arawn.
Keep it steady and zoom out.
For thousands of years, humans have gazed toward Aswan
He kept being amazed.
I was continually amazed.
Moreover, he has also tried to understand it.
Nearly two thousand years ago
In Igbo, there lived a Greek mystic.
Airtos Phynis
He was the director at the Library of Alexandria.
He read it somewhere.
The city of Sain, today's Aswan
Exactly twelve o'clock at noon there
If there is a tree planted on the earth
It doesn't cast any shadow at all.
But it is the city of Alexandria.
If there is a wooden stick lying on the ground there
I become its shadow.
This point was not understood by Eirtos Tens.
He began to think
If you are an heir and the flat is yours
A shadow of a stick is forming somewhere.
Why shouldn't his shadow be formed elsewhere?
It has become clear to me from this.
that the inheritance in question is
It's not a flat.
She is a bit clumsy.
How many people are there?
And when he put on the goggles
I finally understood it.
every 800 kilometers
Rafli is the heir to the throne.
What's changing with the English here
It is 7.2 degrees.
It has become clear to me from this.
That if that is indeed the case
Then, to completely fill the entire circle
Mits karni padegi
Then the inheritance will be fully settled.
And he came.
Forty thousand kilometers
Think about it
A man had a walking stick.
And with the help of its shadow
Two thousand years ago today
Tell us this
That which is our heritage
What is its circumference?
And also tell this
That's not a flat.
Before telescopes and compasses
When the stars looked at the sky
They were trying to understand it.
When our ancestors looked at the stars
You reached that point
They used to estimate it from time to time.
Which season is coming?
Which fruit will ripen next?
When do the animals need to start migration?
This was all possible because of that.
because they have stars
And the circulation of the plants
We had tried to predict it.
And they also walk in a pattern.
When they saw that
Following a pattern
Then it seems that heritage itself is the center of the universe.
That's exactly what the saint said.
Ptolemy in the second century
He had said, "It has already been settled."
That inheritance is the center itself.
This is the universe.
Check above if you're not sure.
The stars that are coming are the same ones that are leaving.
Following a pattern
And upon looking, it seems exactly like that.
No one has ever bothered to touch upon his words up to now.
Absolutely accepted.
But then in 1543
A saint came from Poland.
Nicolaus Copernicus
He said, "No, brother, no, it's not like that."
We don't need to emphasize it too much.
This universe is around us
Ryolof is not doing it.
Indeed, we and all the other plants remaining
They are circling around the age of Aron.
This was a very major revolution within science.
Because humans are no longer the center.
Became part of a large system
Sixty years later
A German saint, Johannes
Kepler has already proven it and shown it clearly.
Brother, this entire sphere
Circles are turning, listening to it
They are not circling around.
Rather, they are forming an ellipse.
The first form of
Kepler also explained that
And what about this sound?
Who has any magnetic force
Due to which all these plants
They are attracting his attention.
And it was precisely that thing which was Newton's
He gave us the theory of gravity by going ahead.
Originally, the Romans who were
They went to the Venice Plant
The gods of romance believed it.
And on March, he was the God of War.
You thought so, but the truth is different.
Exactly, they say, the universe is separate.
Where is the toilet?
You go to Vince's.
Because Venus is so close to it
And the temperature there is also
Stays up to 480 degrees Celsius
Those who are called are also chosen.
They are made of sulfide acids.
Through its entire atmosphere
96% is carbon dioxide.
All of this combined makes a greenhouse.
They create a greenhouse effect, like Venus.
Completely hot pressure
And Romans had it
The guard of Romans was established.
Which romantic trip would you like to go on, brother?
If you look at Venus again in March
It's a bit cold.
It's also interesting.
He is the one closest to inheritance.
That's why Elon Musk is also saying they go there.
They call it a colony, and a little bit from inheritance.
That's why there are ice caps there.
And a day is also twenty-four hours long.
That is why people believe.
that if anywhere Alan will be
You could be there in March.
At the end of the 1980s
An American astronomer
When I looked at Mars through the telescope
When he saw it, he felt
There are water canals on Mars.
He became a martyr.
He began to think: if the canal
He was my brother; he had fallen from Canal Road.
says if there are canals
There will also be intelligent life in this matter.
Aliens could also be there.
That was when, later on, the high-altitude satellite
Then I realized there was nothing like that at all.
They were not water canals but rather
Optical illusion was a thick old one.
Who was looking through the telescope?
He thought this canal road was going there.
But the words are marching.
Those who live on Mars, they're a popular one.
Today we clearly know what Mars is.
It is a frozen dessert.
Where the temperaturas range from zero to
They go up to a hundred degrees.
There isn't any water at all on the surface.
But ice caps are certainly necessary.
It means the water that is there has gathered.
If we somehow manage to melt this ice
Let's make some oxygen.
And if we build a shelter, perhaps we ourselves will become the shelter.
March
Brother, there's also a movie based on this concept.
March is very beautiful; just take a look.
When we look at these billions of galaxies
And they look at the trails of planets
A question surely arises in our hearts.
Are we alone?
Or else in this universe
Is there any other life?
It would not be wrong to think that.
That there is also life elsewhere
But if they are aliens, how would they appear?
Who is Green Clover's wife?
They have very big eyes.
Carl Sagan says it's not necessarily so.
as if the aliens were looking at them
He says, "Take an example of your heritage."
How many varieties are there in life here?
From bacteria to worms
From the plant to the yogurts
They are made in various different ways.
How did we ever come to imagine aliens like this?
He says that if any plant has
The conditions are completely different.
because gravity there is different as well
The winds are different too.
The temperature is also different.
The crutches that will be produced there
They will be completely different as well.
Then Carl Sagan gives the example of Jupiter.
What if life existed on Jupiter—how would it be?
The entire planet of Jupiter
There isn't even any land in it.
It is a gas-powered plant.
If life existed there, I would think
You too would be gas.
There are large bubbles of gas.
There are gas bubbles spread out over kilometers.
They can cook their own food.
Like photo synthesizers
Just as plants grow on our heritage
If I were an alien
How will they talk to us?
First of all, there won't be any face-to-face meetings.
There are much higher chances of that happening.
if they are aliens
You might be able to via radio waves.
Send a message please
Because Radio Waves is such a method
The one through whom you can send your message very quickly
They can extend over a very long distance.
What Carl Sagan is saying
If there is such an intelligent life
He will surely know it.
Those bullets that are still on them
But if they send any message
What should I send?
Carl Sagan is saying
that he might send such a message
Like a prime number
2, 3, 5, 7, 11
Prime number because
What is Mithra is one and the same throughout the entire universe.
It could become a language like that.
They will also understand it.
We will also understand it.
And it will be clear from the prime number.
I remembered after sending the message
We have delivered our message.
Yes, the 1990s
NASA sent two spacecraft.
Voyager 1 and Voyager 2 in space
This is no ordinary one.
It's not a spacecraft, it's not a machine.
Rather, this is a cultural ambassador.
These two spacecraft are
Launched in Ninety-Seven Seventy-Seven
That is their purpose.
that they may go far away from here
And tell us what is inside this chest?
These spacecraft are still alive.
And the human sent into space
The farthest thing
These are the only two spacecraft.
A backup system is also installed inside Voyager.
that if one part fails
It becomes the second reply.
plutonium inside for the power source
The source of nuclear energy has also been added.
It is slowly descending.
The funny thing is that in those spacecraft
There are also wine records.
They weren't wine recorders, those old-fashioned ones from bygone days.
In which they kept the needle
They are also present in that spacecraft.
And those that are vinyl records
In sixty languages
Greetings are here
That item, if obtained by any alien
When you run the disk
In sixty different languages of inheritance
It will give him a hello.
In addition to that, on these discs
Music from around the world is also there
Nature also has its sounds.
Wind, electricity, water
The beauty of humans
DA's sketch along with it
He has also read it in those spacecraft.
A map of the entire solar system is also kept by them.
ever met an alien
You will see what he will say
Alright, what is this? Where did this come from?
Carl Sagan's "Pale Blue Dot"
I designed it myself.
He said that if anyone is intelligent
When life happens, don't let it turn out this way
so that he may come to know us only through bad things
Brother, wars are fought here.
Here, blood becomes a mess.
They're nuclear-attacking each other.
That's why the first explorer we have is
It has been given to the alien as a gift of beautiful things.
We often see it, and then we realize.
Brother, this scientist was also European.
He was also European.
Let me tell you that science did not originate in Europe.
rather, Westin philosophy and
The true origin of early science
It has become the Inshant Grez.
In the colony
The colony's name was Ionia.
The region of Ionia is today's modern...
Who were the people in Ionia in Turkish?
They used to trade a lot.
The countries that were near them
Egypt and Babylon
The people there used to pray to various gods.
We thought that
Ejepsen says our God does this for us.
They do it, the guys from Biblawn are saying
Our God does it, they do it
We thought that Bhagat is everyone's God.
They're doing something strange.
Or are there some laws of nature?
The thought that was there
That was very revolutionary.
It was intense scientific thinking.
They said, "Brother, behind every single thing"
They are our God.
It's something entirely different.
Understand it in this era.
The birth of early science occurred.
In those days, there was a flautist.
Democritus
Democritus came up with an outstanding idea.
He said that whatever things there are in the world
Whatever things exist in the universe
Tiny invisible particles
The one to whom he gave the name of Atomos
He said that if there is an apple.
When we cut it
You are actually this atom's
They are passing through empty space.
Because even the smallest atom cannot be cut.
He said this in 430 BCE.
And two thousand years later
This thing really turned out to be true.
Yes, sir, an atom is indeed something.
However, not all people appreciated this approach.
Pitha Gurs
After that, the plate.
Then there was Aristotle, who was
These were the flow sensors.
The theory they had
It was completely different from how the universe was seen before.
They regarded the universe as a divine entity.
And they thought they were perfect.
They said this should not be conducted as an experiment.
That is a big mistake.
The universe is absolutely perfect.
Leave it as it is and think.
They thought science was merely something to ponder.
We had money, didn't we? What should we do?
But that alone is not enough.
Carl Sagan said that their influence was so great
that he had stopped science in its tracks
And then, when the custody came
He also reformulated the same thing.
that the universe is absolutely perfect
There is no room for questioning in this.
For this reason, science was further suppressed.
For a thousand years, people were afraid to experiment.
Then, was it hundreds of feet?
The Renaissance in Europe
When a person regains that same enthusiasm once again
who did not want to believe in everything blindly
The question I wanted to ask
I wanted to experiment.
Ninety hundred such as these
A young scientist
It completely changed the way we understand this universe.
He was the man.
Albert Einstein
Through your own thought experiment
It completely changed the way we understand the physics of the universe.
It was also a thought experiment by Albert Einstein.
What happens in a Thor experiment?
You only think about it in your mind.
That is why they are called thought experiments.
This is exactly what Aristotle and Plato were saying.
Go ahead and conduct such an experiment, okay?
The thing that Albert Einstein did
He has truly gone all out.
One of its famous and well-known samples
Thor's experiment is underway.
What it says is that
Think
That you are going in a car
The one whose speed is 100 kilometers per hour.
And from this car, you throw a single hair.
When I was young
The speed of the vehicle will be checked.
You will become that.
Arrive at the kilometer mark of one hundred.
Because it's at twenty kilometers up
What was the speed of the ball?
Then, what was the speed of your car?
Arrived at 10 kilometers.
She will become plus in it.
That's easy, isn't it?
It's beginning to make sense.
But Einstein says
that thing
It's fine in Bal's case.
But something is not right in Light's case.
You're thinking about going in the car.
R at 10 kilometers
And you turned on the car's headlight.
The light is trolling.
three hundred thousand kilometers per second
And then the car's what?
The speed is 20 kilometers per hour.
Technically, he is in it.
It should be added.
But Einstein says
No, that's not how it works.
At the speed of light
Your car's speed
It doesn't work.
She remains the same.
The speed of light never changes.
It is a constant.
If it does not change
Something is changing, that's for sure.
And he is the one.
Time and Space
They are not faxes.
They are a band.
Sensitivity to speed and gravity
Inside it now
I won't go any further.
It will become complete.
But that was it.
Theory of Relativity
What a wonderful talent indeed.
Thinking and pondering while sitting down
You've made such a big discovery.
for whom he has it
No need even for a laboratory.
Why, that will be the case.
What was I thinking?
If it's going to be like that, then let it not be so.
He just said something like that.
You've said something very important.
For several centuries, people had
To carry out experiments
Almost considered it a sin already
Then in the hundreds of feet
When people started asking questions
Why
How?
And what if
This question regarding this proposal
It seemed as if
Humanity has risen from the depths of despair.
It was the very same period when
Galileo Galilei
Lingnan Tower in Pisa
What did they experiment with?
in which he
Two different sizes
agents
A stone
And a feeder
A wikium built
When thrown
You two as well
At the same speed
Come down here
Fell to the ground
Who from him
Concluded this result
that if there is no fraction
Wikiom is
To Abjants
Whatever kind they may be
Whatever their weight may be
At the same speed
They fall down below
And then came Isaac Newton
He said that
Yes
That is precisely what we call gravity.
Everything to one another
Attracts
All of this
The thought of these ions
The ionine thought that
She used to say
that we had
I just can't believe it.
We'll see.
To learn
To experiment
To test
Then you must believe.
That's exactly what I was thinking
You know, right?
Science
And she is a strong girl.
And that very thought
What do you mean by scientific thinking?
Because of this way of thinking
A human being
Bridges have been built over the streams.
In the air
Has learned to fly
And finally, him
Space Tech has also reached there.
For thousands of years
These stars
They only existed in fairy tales.
During the cold wave
Soviet Union
and the United States of
Space Rice is lagging.
Each other
Caught up in the cycle of showing off
What did they do?
It has progressed in space.
He is very talented.
The rockets that came first
They used to go to the market.
People have started leaving one by one.
And even in space
Ninety-five seven in
Rishian's first satellite
Sputnik launch
Then in Ninety-sixty-one
The first human to go to space
He was also a rishi.
Yuri Gagarin
and in the 1960s
Then he went toward the United States.
Neil Armstrong
The first man who ever
Placed a foot on the moon
And its famous line
How could they possibly forget?
When he took the first step
He was keeping it on the moon.
You said that to me.
For humanity
Humanity has now advanced this far.
A question comes now.
What good does it do to know all this?
Why do they do it?
This is space exploration.
They say this about Carl Sagan
Brother
Pure Science Numbers
Mathematics
And it's not a formula either.
Moreover, science provides a theory as well.
He says
When we have so much waste
They look at the universe
Let's try to understand it.
You make us realize
that our problems are
How small they are
Our wars
Our geo-politics
Our Ego
Everything small
A blue marble is rolling.
whose name might also be
Nobody even knows about Ellie.
You're realizing this
One of them makes us humble.
We are not the center of this universe.
Yet alongside it
It also makes us aware of this fact.
They are specifically for this purpose.
Because as far as we know
where inheritance alone is that place
Where life has been found
This is the very place.
Where humans have written
Thought so
I have had a dream
They say this about Carl Sagan
Not only information is obtained from science
Moreover, a way of thinking is also provided.
Aynenz has given us
He has taught me how to ask questions.
Not sure about spending
Einstein gave us
Has taught me to imagine
Not taught to remember
I was not taught to retaliate.
Every discovery
From gravity onwards
Radio Verus to
That's exactly why it is.
Because no one had
Began asking questions
Carl Sagan says
that
He does not have all the answers.
But one
Neuwerendinge
Sarchipor Troz
It is necessary.
And if scientists
Even if something turns out to be wrong
He doesn't consider it bad.
Carl Sagan says
who we
The universe right now
Who are you able to see?
That's his.
It's a very small part.
The rest are vegetables
Dark matter
And dark energy
It has been built by him.
What is invisible?
We can't seem to see it at all.
All that we are able to see right now
It's only five percent.
Ninety-five percent
You are the one.
What we cannot even see
This is such an example.
As if
A human being
All the way from Lati
The day the world began to turn upside down
Until March's Ruors
One thing has remained constant.
And there she is.
Espionage
Curiosity
And it is this very thing that distinguishes humans
and leads toward exploration
Carl Sagan says
that we
They are part of the universe itself.
The one who is the universe
She is trying to understand herself.
We are all literally
They are made of Star Dust.
You too, sometimes
You were a part of a star
I too was once a part of a star.
These are the items inside our body.
Never
They were made in a star.
Technically, when you
Looking at the sky
And
You are looking at the stars
You are his too.
It is a part.
You're welcome.
One part of your own
Who are you looking at?
This is the heart of humanity.
Connects to this universe
You only
of this very large universe
Small
It is not an ordinary share.
We are that part.
What can be thought of
And it is precisely this thing
This little one
Blue Marble Co.
Special beauties are there
Carl Sagan says
that
Yes
You are also the result of those very stars.
Whoever burns someday
You died once
When you look at the sky at night
And let another broken star pass by
Understood.
This universe is yours
She is sending a message.
And she's saying also
