00:00hello everyone this is your first lesson

00:03under earth and life science subject

00:05ninosas in your eye which is about the

00:06origin of the universe

00:10from the tiniest particle punta sapiena

00:13i'm going to show you here some pictures

00:15because we need first to define

00:18this is earth and we live on this rocky

00:20planet and this is part of the solar

00:22system together with seven more planets

00:25we call it solar from the latin word sol

00:27meaning sun and the solar system it is

00:29part of the milky way galaxy together

00:32with 200 million stars and the

00:34milky way galaxy it is one of more than

00:37a 125 billion galaxies that make up what

00:40yes the visible universe ortonata

00:46according to our definition right here

00:48the universe is the whole cosmic system

00:50of matter and energy of which earth and

00:52therefore human races apart so as in

00:55everything from the atomic level up to

00:57the biggest stars in galaxies yes

00:59parchin and universe

01:01union creation myth that is number one

01:04and number two is scientific theory

01:07origin of the universe

01:10let us start with creation myth

01:12according to the definition it is a

01:14symbolic narrative when we say narrative

01:17and when we say symbolic then that story

01:20stands for something else and that

01:22something else is the beginning of the

01:24world as understood by a culture so it

01:26is something that concerns the existence

01:29of the universe as understood by a

01:31culture or we can say that as understood

01:33by a particular religion so alibaba is a

01:36genesis the creation of the entire

01:38cosmos took place in six days the

01:41biblical creation tells that god created

01:44now in creation myth cannot consider

01:48when we say sacred banal

01:51participation on supernatural forces

01:56spiritual being a god a transcendental

02:01considering a secret now

02:06so number one all creation myths are

02:08ideological of course etiological

02:12etiology it is the study of causation or

02:14the origination of something so on

02:18what might have caused the creation of

02:20the universe by a supernatural force or

02:22forces perhaps an obeying intention and

02:26and it is also philosophical and

02:28theological in the way it is elaborated

02:31because an existential philosophy of

02:33life that's among adherence and of

02:36note that theology it is the study of

02:39god and lastly it it assumes a spiritual

02:44is that there is someone or something

02:46or can be many of them that has or have

02:49the dominion or rule over the material

02:52world yes meron material world

02:54in the experience by our senses and

02:56there is also this spiritual world kung

02:58sandi dwell human experience okay and

03:02before we end up the discussion about

03:03creation myth i have this question to

03:23okay so what do you think about it

03:26so let us proceed at the next part which

03:28is about scientific theories about the

03:30origin of the universe let us start with

03:33the theory that is most accepted by the

03:35scientific community about the origin of

03:37the universe which is about the big bang

03:39theory it was proposed by alexander

03:41friedman essential mathematician and

03:43physicist at the george

03:48there was nothing and nowhere but due to

03:50random fluctuation in an empty void

03:53there was a great expansion can you

03:55imagine that there was nothing and

04:14it takes no time random if everything is

04:16created from the random flaw from random

04:28i think it is just good to ponder on

04:29this small thing and put a spice of you

04:32know philosophy now going back so

04:34remember that this is not an explosion

04:43but in the again it was an expansion

04:47the vacant sending space time and matrix

05:10they are moving further apart so if the

05:13universe is expanding

05:20by theory and after millions of years by

05:23human hydrogen gas they clamp together

05:27and that's a great pressure in gravity

05:29because in the work nigerian gravity is

05:31among the fundamental forces of nature

05:38four fundamental forces of nature they

05:40form among stars in galaxies so ayun

05:43allaman di natin and masters are mostly

05:47okay so we go back to the beginning

06:02it stopped working now what if the big

06:04bang is the end of the previous universe

06:07and after the big bang creation universe

06:10then perform only into singularity

06:16universe in international cyclic modern

06:18universe young bigbang and existed being

06:22shifting periods destruction and

06:28and we are done with the expanding

06:30universe theory now proceed into another

06:33alternative theory and origin of the

06:35universe it was proposed by thomas gould

06:38fred hoyle and hermann bonding on

06:40midnight 20th century so the theory

06:42proposed that the universe is unchanging

06:44in time and uniform in space

06:56is that steady theory i agree that the

06:59universe is expanding the answer is yes

07:02now how come now universally expanding

07:05peril and i'm unchanging the say i is a

07:08perfect cosmological principle okay so

07:10the universe is homogeneous and

07:12isotropic in space and time the same as

07:16it always has and always will and

07:19the universe appears to be just the same

07:21so it appears to look the same in a

07:25okay so a magrilla lamuna tigers a given

07:28definition zomai mas definitions

07:33it also views continuous creation of

07:35matter at the same rate that old ones

07:38become unobservable so dito nasa hoping

07:40observe young universe belong expanding

07:45recessional velocity

07:47among astronomical objects

07:50expansional universe now

07:55expansion new amount of matter

07:57in a given region of space

08:05uh universe i am changing

08:10isotropic continuous creation of matter

08:13at eins theory will are in creation at

08:16destructional universe so it does not

08:18predict the future okay it

08:53which contradicts the evidences okay

08:57let us proceed to the inflation theory

08:59it was proposed in 1980s by andreas

09:02allen guth paul steinhardt and andre

09:05lien the inflation theory proposed a

09:07period of exponential expansion of the

09:10universe prior to the more gradual big

09:12bang theory uh inflation theory is

09:15actually a extension on its standard big

09:17bank theory it was uh able to solve the

09:20limitations of big bang theory in the

09:22ninja challenge don't say standard b by

09:24theory because i'm a genuine flatness

09:26problem which is a geometry in the

09:28universe and your horizon problem the

09:30halden say uniformity now cosmic

09:32microwave background the tradition pero

09:49proposed in 1960s by jen by john

09:51schwartz so indeed the assembly of

09:54particle type is replaced by a

09:56one-dimensional fundamental building

09:58block called stream ethereum is

10:00replacements of fundamental building

10:14fundamental building block where we can

10:16still think of a string as particles in

10:19a larger scale for strings to be

10:21recognized as just particles

10:26properties like you must okay again

10:28we can still think of a string as

10:31particle sparrow not a larger scale

10:34and there is only one type of string but

10:36this string can vibrate into different

10:38ways and interact with other strings so

10:41starting illustration we have here

10:43graphite which is made of carbon atom

10:53chemistry okay and then proton at

10:55neutron a deeper union fundamental

11:03made of strings just like ordinary

11:06strings but a lot of physics are going

11:08on there okay it only is 330 i might aim

11:11it on a connect on general relativity in

11:13einstein which is studying the world of

11:16the very large engine quantum mechanics

11:19studying the world of the very small

11:28it will be a breakthrough sufficient

11:31and that's all for our lesson the origin

11:35i hope you learn and thank you so much
