00:00:01

science program and today's topic is the

00:00:04

telescope on the web.

00:00:07

Please follow

00:00:09

[music]

00:00:17

[music]

00:00:25

before going into the topic. Please

00:00:28

Please look at the picture

00:00:30

above on the board. You can see this. This is a

00:00:34

picture taken in 2005. This is a model

00:00:37

of the telescope.

00:00:40

Observation website. The model lets us see, first of all, the

00:00:42

size is very large.

00:00:45

Its length is 22 meters, its width is

00:00:47

12 meters and its height is also about 12 meters,

00:00:50

meaning it is as big as a tennis court.

00:00:53

Well, if it is that big, people will definitely

00:00:55

have to fold it to make it smaller, which makes them look uncomfortable.

00:00:57

And the spacecraft must also be able to launch,

00:00:59

so this picture is from 2005, 16

00:01:03

years later it hasn't changed at all. It proves

00:01:06

that people have spent a lot of effort

00:01:07

to improve it, then you will see it on

00:01:11

January 25th. December 2021 Then in an

00:01:16

overseas territory of France located in South America,

00:01:19

on the archery base, the

00:01:23

French Arirang 5 rocket launched a telescope. Well,

00:01:29

everything is known from the web and space. December 25

00:01:32

is Christmas and it is the

00:01:36

day that humanity welcomes sentient beings

00:01:39

as well as in the context of the

00:01:41

coronavirus epidemic with images. Yet the

00:01:44

images you see here are The photo tree that

00:01:48

we are flooded with on this December 25

00:01:50

photo of our number of arirang 5 Mong The

00:01:56

telescope and space will also be

00:02:00

added as to why people choose

00:02:01

the showroom Because Euro is it is located near the

00:02:05

road Our equator takes advantage of the

00:02:07

Earth's centrifugal force to increase

00:02:10

its power. At that kilometer from

00:02:14

123, the two lids push the

00:02:17

luggage compartment open and we can

00:02:19

see it. The telescope is about to meet

00:02:21

again and at an altitude of 230 meters, the first thing

00:02:26

is the rocket booster that falls out,

00:02:28

both of these things fall out when the

00:02:30

rocket how much does it cost per kilogram? Why? That

00:02:32

means we were

00:02:34

all scared and at an altitude of

00:02:38

1380 km, the

00:02:42

telescope was launched to

00:02:44

everyone's joy. The picture you see

00:02:46

above is a model. simulation This is a

00:02:49

real image to present, so

00:02:52

we can see that the girl is very good. It keeps

00:02:54

flickering and these are also the

00:02:57

same images that people see from

00:02:59

this moment on it will go far and wide. If

00:03:02

there's any problem, no one can solve it for

00:03:03

us. The horse's eyes are always clear.

00:03:06

From now on, we can monitor

00:03:08

the flow of menstruation clearly like this.

00:03:10

Let's call t. This is the

00:03:13

moment when launch the rocket

00:03:17

arirang 5, then T is the liberation, then on the

00:03:22

12th day, then all the parts

00:03:26

on the tree at the website to calculate the

00:03:28

web game have been opened and so on the

00:03:31

29th day then it will go to point L2 to

00:03:35

track from you can type the word

00:03:38

web game hacking above the net penalty on

00:03:40

YouTube maybe you can see

00:03:42

if the real location with the

00:03:45

real speed is today January 5th

00:03:48

means I'm doing

00:03:50

these programs 11 days after going online,

00:03:53

just a

00:03:54

few minutes ago I checked it and it's

00:03:56

now gone out of the earth, it's

00:04:00

950 thousand km away from the earth, the point is L2 means it will arrive

00:04:05

within 29 days after it launched,

00:04:07

meaning it has

00:04:10

been 11 days since it launched it today, but it has already gone

00:04:14

2/3 of the way, you know that

00:04:17

if that is the case, then luck will be there. The speed of the site

00:04:21

will change over time. When it first

00:04:24

launched from the district,

00:04:26

its speed was about 600 meters per second, but

00:04:29

now it is only 4 km. This will

00:04:31

slow down more and more. On the 29th day, we will

00:04:34

keep the decided L2 point.

00:04:37

We will talk more deeply about when we reach the

00:04:40

point you are two, we will see that it

00:04:42

will rotate for a human Ellipse-shaped irit

00:04:46

at the time it rotates. Turned

00:04:49

on all its devices,

00:04:50

tried it, and six months later,

00:04:54

what does it mean when it goes live? It means that

00:04:56

by July 2022, humanity will

00:05:00

receive the first images of its own

00:05:01

web. sent back from space. Here,

00:05:05

please consider it as an improvement.

00:05:08

When it opens its equipment,

00:05:10

30 minutes later, when it launches, it opens the

00:05:15

solar panels so it can

00:05:18

start. It takes energy to operate.

00:05:20

Three days later, it opens the plates. Let's call it the supporting

00:05:24

plates. The antenna is

00:05:26

under the antenna. It's located here, self-strengthening the center of the first pole

00:05:28

completely so that the

00:05:30

2B plates can be installed. The shields of the

00:05:33

solar panels and then it

00:05:36

will open up what is called the energy field, the

00:05:40

force is this, the

00:05:42

energy head is the wing to help the

00:05:44

spaceships move. It's the

00:05:46

most stable and energy-efficient way

00:05:49

to say that it's a spaceship. You

00:05:53

use solar energy to

00:05:56

transfer data, but

00:05:59

to move, it has to use solar energy.

00:06:01

Its own energy points here,

00:06:04

the taste is the reflective panels

00:06:07

against seeing the body of the sun. It is

00:06:09

slowly opening the seventh day and on

00:06:12

Saturday it opens completely.

00:06:14

What we see here is There are about 5 tons. On the

00:06:17

10th day, the auxiliary ant will

00:06:20

open the auxiliary mirror, which is as big as a plate.

00:06:22

On the 11th day, the two

00:06:26

glasses on both sides will open. We know that

00:06:29

the language is very careful. If it's big and folds up

00:06:31

the sign, then on the 13th day

00:06:35

everything will be considered finished, which means

00:06:38

we will have to wait two more days from the

00:06:40

moment I said to see if everything is done

00:06:44

and if you can take it. The way

00:06:46

the mirror works is like this. The

00:06:48

View It will catch light from the planets,

00:06:53

celestial bodies in the universe and stars, it will

00:06:56

reflect into the secondary voice and it will

00:06:58

reflect back a second time.

00:07:00

the point of the main fairy and then it goes through

00:07:03

many lenses so it goes down like

00:07:05

that part is under the

00:07:07

landscape part to wait here there will be four

00:07:11

lenses four sets sorry four cameras

00:07:13

so it analyze all the light

00:07:16

received before it laughs so that the earth game wakes up you

00:07:19

guys like me it shows up

00:07:22

then the

00:07:24

web people it is on its way to the point

00:07:27

which is very two points rangan L2 is the point away from the

00:07:31

earth

00:07:32

1.5 million km and it lies below the

00:07:36

earth-sun line, the point is

00:07:40

potential energy which is the test score, but the point

00:07:43

is ice is very electric things is the

00:07:45

point defined by Mr. Leggings

00:07:48

who found Olga stops at the

00:07:51

Rogers point. The advantage is that the balance between

00:07:57

two moving objects in

00:08:00

the universe is

00:08:05

5 points in the Earth's solar system tree, and other

00:08:09

scientists have chosen the village point that gl2 because

00:08:13

at this point the orbit is stable

00:08:16

and the conditions for

00:08:18

transmitting all the data to earth are

00:08:21

very good. If this L2 pad

00:08:24

does not rotate, then here it is. To

00:08:27

see clearly, I would like to present it

00:08:30

like that. Imagine you

00:08:32

stand that outside the Universe, the sun is

00:08:34

here, it is yellow and the

00:08:37

earth is blue, then at that point L2. then

00:08:40

Zen web will rotate in an

00:08:43

Elliptical orbit and determine that it is irregular, one side is

00:08:47

800,000 and the other is 600, nearly ten thousand kilometers,

00:08:50

then here is our frontal view

00:08:53

for you to see, but if we cut it

00:08:55

horizontally, then We will see that

00:08:57

its orbit is not

00:09:00

in the same plane, its

00:09:02

shape is distorted, in short,

00:09:04

its orbit is a trajectory in

00:09:06

the space of 3 million.

00:09:07

In this picture, you will see

00:09:10

more clearly. What is this here?

00:09:14

This blue arrow is drawing the

00:09:17

orbit of the earth around the sun and

00:09:20

tangerine. And the blue color here is the light.

00:09:22

here the blue orbit this is it draws

00:09:24

jane whaff's orbit around the

00:09:27

sun then we can say that D1 web

00:09:31

is a geostationary satellite of the earth

00:09:36

called a geostationary satellite which means the

00:09:39

speed Its rotation around the sun

00:09:41

will be equal to its cylindrical rotation speed, it will be equal to the

00:09:43

earth's speed, then what you

00:09:47

see in the yellow orbit circle

00:09:50

here means that it is the orbit

00:09:54

around you. Why does the sun and the earth's axis have to

00:09:57

rotate? It can't be

00:09:59

said to be stationary. There are two reasons:

00:10:01

what I just said is that it is a geostationary satellite,

00:10:04

which means it must ensure that the angle of

00:10:06

rotation and rotation speed are met. Its speed must be equal to the

00:10:08

rotation speed of the earth around the

00:10:09

sun, so it must rotate

00:10:12

to ensure it is safe because we

00:10:15

should not forget that the distance from the earth to

00:10:17

the sun is not always the same.

00:10:19

A bad guy changes sometimes he

00:10:22

uses it. Almost always, that means the

00:10:25

L2 also changes, then the

00:10:27

other one is good, change your position or

00:10:29

change, the one on the web also learns

00:10:32

to rotate. For anything, the speed

00:10:35

is always equal to the earth, the second reason

00:10:37

when spinning.

00:10:40

Don't forget that the distance from the

00:10:43

earth to the w is 1.5 million km, it is

00:10:47

only one percent of the distance. The distance from

00:10:49

the earth to the sun

00:10:50

Yes, if it did not rotate, it would be

00:10:53

temporarily called light. It is covered by the earth's surface and

00:10:56

water, it cannot be recognized as sunlight.

00:10:59

Yes, it must rotate. We

00:11:01

forgot Don't forget that its radius is

00:11:03

88 km, so it has more than enough power to receive

00:11:06

sunlight so it can operate.

00:11:12

it would be like

00:11:15

this if we see through the activity

00:11:17

that it rotates in the same direction

00:11:19

as the earth and see

00:11:22

clearly that its orbit is a clip orbit

00:11:25

then what is special of the website is

00:11:28

like this in the web game, we know

00:11:31

its size is really big

00:11:33

its lens diameter is 6.5 m which

00:11:37

is

00:11:39

very much bigger than the others. Ha heard

00:11:41

Tit give a reward but

00:11:43

its special feature is that it is not a

00:11:45

single block but it is made up of 18

00:11:48

hexagonal shapes made of

00:11:50

beryllium barium which is a special substance

00:11:53

that can withstand hot and cold A and

00:11:56

the special point of 4G is that everyone should note

00:11:59

that its positive and negative side is

00:12:01

131m, which means it is very large and the

00:12:05

sensitivity has been evaluated to be a hundred times greater

00:12:07

than a telescope. Current literature is

00:12:10

still active in space,

00:12:12

according to the analyst Theo has a lot of

00:12:16

chemistry, so with such sensitivity,

00:12:18

if the website was placed on Earth,

00:12:21

the website would be visible.

00:12:23

Take a picture of a butterfly with a mark on its

00:12:25

face. The

00:12:26

second important detail

00:12:29

is the operating budget, the

00:12:31

budget for putting on the website is 10 billion dollars,

00:12:34

but this is not a small and special amount of money.

00:12:36

It has the participation of many countries.

00:12:39

Italy is the largest country in the United States,

00:12:42

but Europe and Canada have also

00:12:45

participated, so the design as well

00:12:47

as the management of the

00:12:49

design time is 315 Oh my God.

00:12:54

Knowing that the land has been there for 30 years, 30 years

00:12:57

means that since steaming was

00:12:59

launched, we have been thinking about

00:13:00

building on web A and the number of staff to

00:13:06

implement it as well as to run it meets 10,000

00:13:08

people. Is there a small number

00:13:10

? Before going into details,

00:13:13

please open and review the last image, which

00:13:15

is the image of the website. Now let

00:13:18

's get into the important parts and talk about

00:13:20

the mission of SIM. My website's mission

00:13:22

seems to be very important. It's really

00:13:24

important. The

00:13:26

first job of the

00:13:28

website is to find the origin of the

00:13:30

universe because I mean it. Answers the

00:13:35

question where we humans come from. The

00:13:38

second mission is to

00:13:40

find extraterrestrial life, which means it

00:13:43

answers the question: Are we the

00:13:45

only creatures in the universe? Or

00:13:47

not paying attention to the taste of the pig

00:13:50

after a terrible explosion, the

00:13:53

dust and gas will now be blown out

00:13:57

and then in motion it will

00:13:59

create galaxies and the

00:14:01

solar system. of today from then

00:14:04

until now it's been 13.8 billion years what

00:14:07

happened we don't know and that's

00:14:10

how the character's first mission is to

00:14:13

do this on the web he

00:14:16

has to use Using a very

00:14:18

large tool called Huong Ma Huong, this

00:14:21

special Huong runs on infrared rays. It is

00:14:24

different from the sad box seen on

00:14:26

Oppo in that its diameter is 2.4 meters and

00:14:30

the diameter is 2.4 meters. Gen W's radius is 6.5 m, it is

00:14:33

3 times larger, its ability to receive waves is

00:14:36

very large, but its characteristics are

00:14:38

infrared rays. Why are its characteristics

00:14:40

infrared because it is compatible with infrared rays?

00:14:43

People can see

00:14:44

things that are very far away, things that happen

00:14:47

to female singers are very long ago, so

00:14:50

people call the website a machine that goes

00:14:53

back in time. Scientists have

00:14:56

calculated that it can Going back

00:14:59

13.5 billion years ago, the universe was

00:15:03

formed in 13.8, which means that people

00:15:06

can know what happened 300 million years later,

00:15:10

it

00:15:13

is a Blank One. For the first time, now

00:15:16

we will go back to the meaning of why

00:15:18

infrared rays

00:15:20

work because of heat

00:15:22

to understand more. Open your eyes to see the

00:15:26

following pictures. The picture on the left is the

00:15:29

picture taken. Now taking the photo on a

00:15:30

platform, whoever is in the woods on the right is the one who

00:15:34

did it. But with infrared

00:15:36

we can see it clearly. If

00:15:37

you're in the same place at the same

00:15:41

time, we'll take a

00:15:43

photo. In the end, we will see

00:15:44

a person standing inside that is

00:15:46

often invisible. And people

00:15:48

regret having used this in

00:15:51

war. However, it is also useful that in

00:15:54

today's time you are the people. During the period when

00:15:56

we were facing the screw

00:15:58

we saw outside the school in the yard at the station,

00:16:01

it was attached to a machine so that people

00:16:03

could measure the temperature of other rows

00:16:05

without being near the horse, it stopped Ms. Here It's

00:16:08

the same way as pigs. However, infrared rays

00:16:11

have another characteristic that

00:16:15

I invite you to follow. You can

00:16:19

look and listen.

00:16:23

Yes.

00:16:25

You

00:16:27

know, how can you not see that it's you?

00:16:31

The sound changes accordingly. time,

00:16:33

this car is near or far from us,

00:16:35

it's interesting, this is called

00:16:38

Doppler effect, doppler effect, I'm talking about

00:16:40

the effect of sound waves, sound waves,

00:16:43

people call them mechanical waves, then ladies and gentlemen,

00:16:46

mechanical waves then it propagates in the light.

00:16:49

Sorry, keep the money in. Talking in

00:16:51

the air, in this picture,

00:16:54

this place is also the moment the car goes out,

00:16:56

we enter, it is getting closer to

00:16:58

us, then it presses the air. Again,

00:17:01

we see that the waves are

00:17:03

compressed.

00:17:04

When we get close to us,

00:17:10

we see that the intensity of

00:17:13

the sound is the intensity of the sound. It's a magnitude

00:17:15

like this. It's very large. We hear

00:17:18

it very loud, but after we pass

00:17:20

this golden point, we see

00:17:22

an event happen. First,

00:17:26

that gate decreases. important

00:17:28

We see the wave expand and then it expands

00:17:31

then people paint it in a different color it has

00:17:33

a reason, it's a little infrared It is

00:17:37

a type of wave but it is a slow electromagnetic wave,

00:17:39

what's wrong with electronic waves?

00:17:42

The important thing about mechanical waves is the degree of

00:17:47

release, the wave length is the

00:17:50

distance measured between the two peaks of the wave,

00:17:53

this wave length determines the

00:17:55

wave length, it determines the sound of the mechanical wave

00:17:58

and the speed. The degree of release will determine the

00:18:00

color of the electronic wave, so here it's about

00:18:05

color. We all know that,

00:18:08

we're in high school, we already know the

00:18:10

experiment, so we use

00:18:11

light to prove it. If we go through a lens

00:18:13

and buy a prism, we will know that it

00:18:16

will separate into many different colors

00:18:17

and what is liberated is

00:18:20

that color, then we will analyze it. But

00:18:23

below, I will explain that color. As I said again, the

00:18:26

country is based on a special basis and the degree of

00:18:29

liberation is the smallest wave length

00:18:32

calculated by Nanomax and you should

00:18:35

remember Nanomax. That is 10 li from - 12, the

00:18:38

smaller it is, the faster it returns. A little bit,

00:18:42

we call it ultraviolet rays, but when it gets

00:18:44

bigger, it feels bigger, then we know

00:18:46

it's infrared rays, maybe infrared rays,

00:18:48

it's a bigger liberating bet, we also understand

00:18:50

what leads to what. Ladies and

00:18:53

gentlemen, I just said that infrared rays

00:18:56

are electronic waves, they will have

00:18:59

a so-called effect

00:19:01

similar to the doppler effect, then through

00:19:04

this image you can see more clearly than the

00:19:06

observers. Help me with this mountain of white hands.

00:19:08

Up here is a

00:19:11

collective life, so move the object to

00:19:13

move when it is far away and then move to commit

00:19:16

suicide near it. Unlike the previous follower

00:19:18

from far away, it will give it a purple color and

00:19:21

now I let it move every time it

00:19:24

moves when we will change

00:19:27

the time it goes away and comes here so

00:19:30

we know it's going towards the infrared

00:19:33

then what if If you look more clearly, you

00:19:37

will see the same thing: when it

00:19:39

stretches, it will be red, when it is

00:19:41

not, we slowly go to the blue shirt

00:19:44

and in the purple water we take

00:19:46

one. Something moves by

00:19:49

moving a bright light. You see it, the

00:19:51

S6 phenomenon and the waveform so that the back

00:19:54

is equal to the first is all, then the back is

00:19:56

long wave, then the red is

00:19:59

equal to the front, it will be 11 purple. This is also

00:20:03

another example, it comes from afar, it comes to us,

00:20:05

it comes to us in white and after being

00:20:08

separated, tries to go away, it will turn

00:20:11

red, then we are missing what

00:20:14

happened 13 billion ago. years it has gone

00:20:17

very radioactive Of course it will become red

00:20:21

according to these principles and to see

00:20:23

it I have to use infrared rays

00:20:27

that's why Duyen web It

00:20:30

has to work and you go To show

00:20:33

you the difference between infrared

00:20:34

or normal light,

00:20:37

we'll observe something like

00:20:39

this. This is a picture that was taken

00:20:41

in 2015 by a telescope at the

00:20:45

Sun. It's still spinning above our heads.

00:20:47

We took a photo at airport 15 and we

00:20:50

can see it quite clearly. But

00:20:53

if we still take this image and

00:20:55

use infrared radiation, it will be the

00:20:57

result. So what will we see?

00:20:59

We will see a lot of details, a

00:21:02

lot of faces of objects that we cannot see with the naked

00:21:04

eye.

00:21:06

These objects are taken as these objects, they are

00:21:09

mixed in the dust they move.

00:21:12

How many years have we been moving in the dust? When we first

00:21:14

moved in the dust, it will see if it heats

00:21:16

up, it will have a temperature and it will

00:21:19

get something, what does it

00:21:22

detect? Let's put two

00:21:25

images next to each other and we will see

00:21:26

the difference with the larger scene,

00:21:28

obviously thanks to infrared

00:21:32

we will see many details and

00:21:34

especially details that happened a long time ago.

00:21:36

However, there is a problem here.

00:21:38

Try to imagine if we

00:21:41

stand and observe the sky, we observe

00:21:45

the sky, but if we stand

00:21:46

between the lights, what we agree with

00:21:49

is the light. of the lamp it will illuminate

00:21:51

our eyes then what is in the

00:21:53

sky are the stars we observe

00:21:54

we will not see clearly because

00:21:56

we are erased by the beautiful scene now if we

00:21:59

turn on the lamp we will Seeing

00:22:01

this more clearly, what can be saved

00:22:03

easily? If we go back to the countryside for a little while

00:22:05

or we go out to sea for

00:22:07

a while, but talk with our tongues. Without this fog, there is

00:22:10

no cloud. If it

00:22:12

rains, we will see more clearly.

00:22:15

Infrared Light also works

00:22:18

on other people. Infrared has

00:22:21

activities and heat on its side, but

00:22:24

it has a heat that comes to it.

00:22:27

Besides that, it is clear that the

00:22:30

quality of the images will be

00:22:32

greatly reduced. For

00:22:35

that reason, we can see that up here there

00:22:38

are photos that are both photosensitive and

00:22:41

scene photos. This material is made of

00:22:43

materials called near-glasses, such as

00:22:45

substances that can block light.

00:22:49

Radiation from the sun is also

00:22:51

stored on this side. We see that this

00:22:55

is a web sunglasses. What can you believe? The side that

00:22:59

shines towards the sun is 85 degrees, which

00:23:02

is almost boiling water. The other side

00:23:05

is - 233 degrees, then you can imagine the

00:23:08

distance

00:23:10

between the telescope and the tree.

00:23:14

Well, it's about I think,

00:23:16

about 34 meters. But the temperature

00:23:20

difference is almost 300, more than 300

00:23:22

degrees. 3 Well, this is the way the

00:23:25

conditions must be said to be very different.

00:23:29

Now we move to what we can call

00:23:33

a cool land. Second, we're looking for

00:23:35

life in outer space. Are we the

00:23:38

only creatures in the universe?

00:23:40

Well, what can we do to live under

00:23:44

human conditions? Earth,

00:23:46

we must meet the conditions for

00:23:47

this, the most important thing is that the place must have water. Let's

00:23:50

not forget that the first creatures

00:23:53

to appear on Earth were located at the

00:23:56

second point, that planet.

00:24:01

there must be an atmosphere integrated with

00:24:04

humans we think there must be oxygen there

00:24:05

must be an Asus Monitor with Carbon dioxide

00:24:08

and other things

00:24:10

and thirdly those planets don't turn

00:24:13

off they will revolve around a

00:24:15

sun of But it has to be filmed at

00:24:17

a sufficient distance. If it's

00:24:20

too close, it will burn up. If it's too far, then

00:24:23

we're right and it's over. Well,

00:24:26

now let's try to observe. This is

00:24:29

our beloved earth. We are

00:24:32

trying to see if there is a planet similar to that. If

00:24:35

a planet

00:24:37

meets those conditions,

00:24:40

first I repeat that it must be a

00:24:43

water sign. So I'll color

00:24:46

it blue. Both must have air,

00:24:50

then ladies and gentlemen, to meet

00:24:54

these two conditions, the planet must have the

00:24:58

correct size, it must have

00:25:01

a corresponding mass, which is the earth.

00:25:04

Why, because suppose It's small like this

00:25:08

but its mass is also small, it

00:25:11

doesn't have enough power to absorb air. Let's

00:25:14

not forget that air is called

00:25:17

air as it has its own weight,

00:25:18

then according to to-ri-xe- Li is an

00:25:22

American physicist. At least in our heads,

00:25:28

just a little bit of 1 square centimeter and 1 square centimeter of water

00:25:31

can withstand a pressure of 76 cm of

00:25:34

mercury and 76 cmhg of dill. about a

00:25:37

kilogram This is a kilogram, that's a square centimeter.

00:25:40

You know, if I put my hand out there,

00:25:42

my hand is the size of 100 square meters,

00:25:45

then my limbs are 100kg and my whole body

00:25:48

is probably the same size. more than 1 ton, then

00:25:51

why don't I become black and beautiful like a

00:25:53

glass because I see in my body I

00:25:56

have forces that also push out, which

00:25:58

double cancels the air speed,

00:26:00

then that's right now. If not If there's too much air,

00:26:04

then it's either lost or it doesn't suck, then if you

00:26:07

run out of air, it'll fly away, then all the

00:26:09

water will evaporate. What happens

00:26:13

then becomes the crystal and then it turns into a disaster,

00:26:15

like we know this point, don't we? There is

00:26:17

air, there is also water and preserves life

00:26:20

and now On the contrary, if

00:26:23

those planets collide when their mass is too large, find the

00:26:27

opposite phenomenon or

00:26:30

because the air has flown away, it will absorb all the air. When all

00:26:31

the air is sucked in, there

00:26:33

is no more air, then the

00:26:37

planet slowly turns into a waste. It's

00:26:39

a love story. You know,

00:26:42

Jupiter is a hundred times larger than Earth,

00:26:43

but we don't live. Yes, it's a

00:26:45

keyboard but we can't go to it,

00:26:46

that's a condition that the website itself

00:26:51

must determine when encountering planets in

00:26:54

outer space. In another detail, when

00:26:57

you say you have to inject hate, the website After

00:27:00

all, it's a piece of glass, so the glass is the

00:27:03

same. It has to be the focal length in

00:27:05

this picture in this very money. This is the exact

00:27:08

picture taken with all the different focal lengths,

00:27:10

so the first one above is the 18mm focal length, which

00:27:13

is a small negative. The last one down here

00:27:16

is the 300mm focal length, but the focal length is big

00:27:19

and we can see the details. The bigger it

00:27:22

gets, the more it's sent, 1000

00:27:25

so we can see the chicken and the dog

00:27:27

first, right? On this website alone.

00:27:31

Its negative is the focal length, it's not

00:27:32

in millimeters, it's in meters, the

00:27:35

focal length at 131 knows it's allowed,

00:27:39

so if we when we look

00:27:41

at a surface, we We

00:27:44

can see this with great clarity.

00:27:47

However, the question I ask is

00:27:49

what do we see with white

00:27:51

infrared? From what we can see

00:27:55

what is called light? They are

00:27:58

rays. bright and attractive, but for the

00:28:01

website it comes up with,

00:28:05

these tigers have to go through something called

00:28:07

suffering analysis, which we,

00:28:10

high school students, know about,

00:28:12

here we are. There is a

00:28:16

spectrum of light that is almost the same.

00:28:18

However, the difference is that every time you

00:28:22

see it, you have

00:28:24

these plans.

00:28:25

The quantity changes and the distance

00:28:27

it changes. The dynamic position changes and

00:28:30

Depending on the location and quantity, one

00:28:33

can determine what kind of

00:28:35

Oxygen Carbon Asus they are and one can

00:28:39

conclude whether life can exist in

00:28:41

those achievements or not,

00:28:43

whatever the program. Our

00:28:46

talk about the word web is given more power.

00:28:50

However, at this point we have a few

00:28:54

questions, is this the best thing to push ourselves? The

00:28:58

question is why do we have to spend money,

00:29:00

humanity costs such a huge amount of 10 billion?

00:29:02

dollars to look for the two goals I

00:29:06

said are very far away, then I would like to

00:29:09

answer like this: research

00:29:11

is necessary, scientific research

00:29:14

is necessary for all humanity,

00:29:16

then we should also Remember that

00:29:20

60 million years ago, there was an event where

00:29:22

a stone named Thach crashed into the

00:29:24

earth and it caused the

00:29:27

extinction of the dinosaurs. What about today's science and

00:29:31

research on the universe? Now I

00:29:34

think that humans If

00:29:37

such a disaster occurs, humans can

00:29:38

avoid it, though humans are doing it

00:29:41

thanks to scientific research that

00:29:44

has avoided the tsunami disaster in the

00:29:45

Indian Ocean. happened more than 10

00:29:47

years ago and with many scientific studies

00:29:50

, we also know that

00:29:51

this is a screwdriver, but through scientific research

00:29:53

we have found drugs

00:29:55

called vaccines to save mankind from

00:29:58

disaster. Hey,

00:29:59

the only thing going like this is that we know that

00:30:02

America, with its financial capacity as well as its

00:30:05

technical ability, is more than capable and can do

00:30:07

it, but they still rely on Europe,

00:30:10

France, Switzerland, and Canada to

00:30:14

help. to make a web page I

00:30:18

think this is a very good thing and eventually

00:30:20

on the web all the image data that

00:30:24

is there will partly be published

00:30:27

publicly on the skin page and

00:30:30

we can go to Let's see if

00:30:32

we can find out where people

00:30:35

like me and you who are passionate

00:30:37

and scientific can find

00:30:39

details that scientists can't get away with

00:30:41

and in the end leave other people's names intact.

00:30:45

If everything works well, the

00:30:48

website will fluctuate for ten years or ten

00:30:52

years. I don't know what will happen, but

00:30:54

I heard that right now

00:30:56

the Americans are preparing for an

00:30:59

absolute apology. The first telescope is called

00:31:02

Long. The third one is called loto. But

00:31:06

that's the story of the future.

00:31:08

Our program is very weak because of the

00:31:11

program and

00:31:13

Today is January 5, 2022.

00:31:16

I would like

00:31:17

to send you best wishes for good health in the

00:31:20

new year. Thank you to

00:31:24

everyone who took the time to

00:31:27

watch and support the channel last year. We invite

00:31:29

everyone to continue to support our science channel.

00:31:31

We still need to press the subscribe button

00:31:33

If you click the bell button and especially advertise

00:31:35

to your friends and your friends.

00:31:38

And now we would like to

00:31:41

respectfully say goodbye to you. Yeah yeah

Description:

Sau 30 năm thiết kế và chế tạo, kính thiên văn James Webb đã được phóng đi vào ngày 25/12/2021 với sứ mạng là tìm ra câu trả lời cho hai câu hỏi mà con người luôn luôn thắc mắc : - chúng ta đến từ đâu ? - chúng ta có phải là sinh vật độc nhất trong vũ trụ hay không ? Với khả năng được đánh giá là phi thường, cộng đồng khoa học của cả nhân loại đang hồi hộp đợi chờ những khám phá của James Webb. Và biết đâu nó sẽ làm đảo lộn mọi kiến thức về không gian mà chúng ta đã có được từ hàng ngàn năm nay. Kênh Youtube Khoa học và Chúng ta được nhà giáo Phạm Minh Hoàng thực hiện với sự giúp đỡ của các thân hữu, bạn bè, đồng nghiệp. Ước vọng của chúng tôi là được chia sẻ, cung cấp những kiến thức về khoa học nói chung và toán học nói riêng dưới một lăng kính hàn lâm nhưng cũng không thiếu những nét bình dân, thân thiết và thậm chí còn có phần hài hước. Rất mong được sự quan tâm theo dõi của quý vị cùng các bạn. Xin mọi người cùng đăng ký để theo dõi cũng như quảng bá đến cho bạn bè. Xin chân thành cảm ơn. Khoa Học & Chúng Ta

A camera icon should appear in the lower right corner of the player to the left of the "Settings" icon. When you click on it, the current frame from the video will be saved to your computer in JPEG format.
