Q & A

What is the definition of the universe according to the script?

The universe is defined as the whole cosmic system of matter and energy, which includes Earth and everything from the atomic level up to the biggest stars in galaxies.

What is a creation myth and how does it relate to the origin of the universe?

A creation myth is a symbolic narrative that stands for something else, specifically the beginning of the world as understood by a culture or religion. It concerns the existence of the universe and often involves supernatural forces or beings.

What are the characteristics of creation myths mentioned in the script?

Creation myths are ideological, etiological, philosophical, and theological. They assume a spiritual world and involve the study of causation or the origination of the universe by supernatural forces.

What is the Big Bang Theory and who proposed it?

The Big Bang Theory is the most accepted scientific explanation for the origin of the universe. It was proposed by Alexander Friedmann and suggests that the universe began from nothing due to random fluctuations in an empty void, leading to a great expansion.

How does the script describe the nature of the universe's expansion according to the Big Bang Theory?

The script describes the universe's expansion as an expansion of space-time and matter in all directions, rather than an explosion into something.

What is the Steady State Theory and who proposed it?

The Steady State Theory was proposed by Thomas Gold, Fred Hoyle, and Hermann Bondi. It suggests that the universe is unchanging in time and uniform in space, with a continuous creation of matter at the same rate that old matter becomes unobservable.

What is the difference between the Steady State Theory and the Big Bang Theory?

The Steady State Theory posits a universe that is unchanging and uniform, with continuous creation of matter, while the Big Bang Theory suggests a universe that began from a single point and has been expanding ever since.

What is the Inflation Theory and how does it relate to the Big Bang Theory?

The Inflation Theory, proposed in the 1980s, is an extension of the Big Bang Theory. It suggests a period of exponential expansion of the universe prior to the more gradual expansion described by the Big Bang Theory, solving some of its limitations.

What are the limitations of the Big Bang Theory that the Inflation Theory addresses?

The Inflation Theory addresses the flatness problem and the horizon problem of the Big Bang Theory, which relate to the uniformity and geometry of the universe.

What is String Theory and how does it differ from the standard model of particle physics?

String Theory is a theoretical framework that replaces the fundamental building blocks of particles with one-dimensional strings that can vibrate in different ways. It attempts to unify the very large scale of general relativity with the very small scale of quantum mechanics.

What is the significance of the Cosmic Microwave Background (CMB) mentioned in the script?

The Cosmic Microwave Background is the thermal radiation left over from the early universe, providing evidence for the Big Bang Theory and offering insights into the uniformity and history of the universe.

Keywords

💡Universe

The term 'universe' refers to the whole cosmic system of matter and energy, encompassing everything from the smallest particles to the largest galaxies. In the context of the video, it is the overarching theme as the lesson explores the origin of the universe. The script mentions the universe as a part of the observable universe, which includes billions of galaxies like the Milky Way, where Earth is located.

💡Creation Myth

A 'creation myth' is a symbolic narrative that explains the origin of the world as understood by a culture or religion. It is ideological and etiological, often involving supernatural forces. In the video, creation myths are contrasted with scientific theories, with examples such as the Biblical creation story where God creates the universe in six days.

💡Big Bang Theory

The 'Big Bang Theory' is the leading scientific explanation for the origin of the universe, proposing that it began from an extremely hot and dense state and expanded rapidly. The video script describes it as a great expansion from nothing, challenging listeners to ponder the concept of creation from random fluctuations.

💡Observable Universe

The 'observable universe' is the part of the universe that can be observed from Earth, limited by the speed of light. The script uses this term to describe the vast expanse of the universe that includes over 125 billion galaxies, highlighting the scale of cosmic structures.

💡Steady State Theory

The 'steady state theory' is an alternative to the Big Bang Theory, suggesting that the universe has no beginning or end and is unchanging in time. The video mentions this theory as one that was proposed to explain the universe's expansion without invoking a beginning, though it has been largely superseded by evidence supporting the Big Bang.

💡Inflation Theory

The 'inflation theory' is an extension of the Big Bang Theory, proposing a period of exponential expansion in the early universe. This theory addresses some of the issues of the standard Big Bang model, such as the flatness and horizon problems. The script introduces inflation as a refinement to the understanding of the universe's origins.

💡Cosmological Principle

The 'cosmological principle' posits that the universe is homogeneous and isotropic on large scales, meaning it looks the same in all directions and at all times. The video discusses this principle in relation to the steady state theory, suggesting that the universe appears uniform and unchanging.

💡Fundamental Forces

In the context of the video, 'fundamental forces' refer to the four basic forces that govern the interactions of particles and objects in the universe: gravity, electromagnetism, and the strong and weak nuclear forces. These forces are integral to understanding the formation of stars and galaxies from hydrogen gas, as mentioned in the script.

💡String Theory

String theory is a theoretical framework in which the point-like particles of particle physics are replaced by one-dimensional strings. The video script touches on this theory as a way to potentially unify general relativity and quantum mechanics, suggesting that strings vibrate in different ways to manifest as particles with various properties.

💡Cyclic Universe

A 'cyclic universe' is a concept where the universe undergoes endless cycles of expansion and contraction. The video script briefly mentions this idea in the context of the Big Bang possibly being the end of a previous universe, hinting at a cyclic model of creation and destruction.

💡Cosmic Microwave Background

The 'cosmic microwave background' (CMB) is the thermal radiation left from the early universe, considered a key piece of evidence supporting the Big Bang Theory. The script refers to the CMB as a uniform radiation that is consistent with the idea of the universe's uniformity and supports the inflation theory.

Transcripts

hello everyone this is your first lesson

under earth and life science subject

ninosas in your eye which is about the

origin of the universe

from the tiniest particle punta sapiena

i'm going to show you here some pictures

because we need first to define

unbinding universe

this is earth and we live on this rocky

planet and this is part of the solar

system together with seven more planets

we call it solar from the latin word sol

meaning sun and the solar system it is

part of the milky way galaxy together

with 200 million stars and the

milky way galaxy it is one of more than

a 125 billion galaxies that make up what

yes the visible universe ortonata

observable universe

according to our definition right here

the universe is the whole cosmic system

of matter and energy of which earth and

therefore human races apart so as in

everything from the atomic level up to

the biggest stars in galaxies yes

parchin and universe

union creation myth that is number one

and number two is scientific theory

origin of the universe

let us start with creation myth

according to the definition it is a

symbolic narrative when we say narrative

story

and when we say symbolic then that story

stands for something else and that

something else is the beginning of the

world as understood by a culture so it

is something that concerns the existence

of the universe as understood by a

culture or we can say that as understood

by a particular religion so alibaba is a

genesis the creation of the entire

cosmos took place in six days the

biblical creation tells that god created

the universe

now in creation myth cannot consider

when we say sacred banal

participation on supernatural forces

spiritual being a god a transcendental

being

considering a secret now

characteristics

so number one all creation myths are

ideological of course etiological

etiology it is the study of causation or

the origination of something so on

original universe

what might have caused the creation of

the universe by a supernatural force or

forces perhaps an obeying intention and

supernatural being

and it is also philosophical and

theological in the way it is elaborated

because an existential philosophy of

life that's among adherence and of

course theological

note that theology it is the study of

god and lastly it it assumes a spiritual

world

is that there is someone or something

or can be many of them that has or have

the dominion or rule over the material

world yes meron material world

in the experience by our senses and

there is also this spiritual world kung

sandi dwell human experience okay and

before we end up the discussion about

creation myth i have this question to

you um

okay so what do you think about it

so let us proceed at the next part which

is about scientific theories about the

origin of the universe let us start with

the theory that is most accepted by the

scientific community about the origin of

the universe which is about the big bang

theory it was proposed by alexander

friedman essential mathematician and

physicist at the george

there was nothing and nowhere but due to

random fluctuation in an empty void

there was a great expansion can you

imagine that there was nothing and

nowhere accost

it takes no time random if everything is

created from the random flaw from random

fluctuations

i think it is just good to ponder on

this small thing and put a spice of you

know philosophy now going back so

remember that this is not an explosion

but an expansion

has

but in the again it was an expansion

the vacant sending space time and matrix

in all directions

they are moving further apart so if the

universe is expanding

into something

by theory and after millions of years by

human hydrogen gas they clamp together

and that's a great pressure in gravity

because in the work nigerian gravity is

among the fundamental forces of nature

kasama young

weak strong

electromagnetic

four fundamental forces of nature they

form among stars in galaxies so ayun

allaman di natin and masters are mostly

hydrogen

okay so we go back to the beginning

big

it stopped working now what if the big

bang is the end of the previous universe

and after the big bang creation universe

then perform only into singularity

form

universe in international cyclic modern

universe young bigbang and existed being

shifting periods destruction and

creation

universe all right

and we are done with the expanding

universe theory now proceed into another

alternative theory and origin of the

universe it was proposed by thomas gould

fred hoyle and hermann bonding on

midnight 20th century so the theory

proposed that the universe is unchanging

in time and uniform in space

is that steady theory i agree that the

universe is expanding the answer is yes

now how come now universally expanding

peril and i'm unchanging the say i is a

perfect cosmological principle okay so

the universe is homogeneous and

isotropic in space and time the same as

it always has and always will and

the universe appears to be just the same

so it appears to look the same in a

larger scale

okay so a magrilla lamuna tigers a given

definition zomai mas definitions

it also views continuous creation of

matter at the same rate that old ones

become unobservable so dito nasa hoping

observe young universe belong expanding

and unchanging

recessional velocity

among astronomical objects

expansional universe now

theory

expansion new amount of matter

in a given region of space

theory

uh universe i am changing

constant universe

isotropic continuous creation of matter

at eins theory will are in creation at

destructional universe so it does not

predict the future okay it

is among evidences

[Music]

which contradicts the evidences okay

let us proceed to the inflation theory

it was proposed in 1980s by andreas

albrecht

allen guth paul steinhardt and andre

lien the inflation theory proposed a

period of exponential expansion of the

universe prior to the more gradual big

bang theory uh inflation theory is

actually a extension on its standard big

bank theory it was uh able to solve the

limitations of big bang theory in the

ninja challenge don't say standard b by

theory because i'm a genuine flatness

problem which is a geometry in the

universe and your horizon problem the

halden say uniformity now cosmic

microwave background the tradition pero

hindi nabuna

proposed in 1960s by jen by john

schwartz so indeed the assembly of

particle type is replaced by a

one-dimensional fundamental building

block called stream ethereum is

replacements of fundamental building

blackmail

fundamental building block where we can

still think of a string as particles in

a larger scale for strings to be

recognized as just particles

particles

properties like you must okay again

we can still think of a string as

particle sparrow not a larger scale

natalya

and there is only one type of string but

this string can vibrate into different

ways and interact with other strings so

starting illustration we have here

graphite which is made of carbon atom

carbon atoms

chemistry okay and then proton at

neutron a deeper union fundamental

uh

made of strings just like ordinary

strings but a lot of physics are going

on there okay it only is 330 i might aim

it on a connect on general relativity in

einstein which is studying the world of

the very large engine quantum mechanics

studying the world of the very small

incompatible pakis

unifying

well

it will be a breakthrough sufficient

science

and that's all for our lesson the origin

of the universe

i hope you learn and thank you so much

you
