Q & A

  • What significant discovery did Edwin Hubble make about the universe?

    -Edwin Hubble discovered that the universe is expanding, which suggested that it must have had a beginning.

  • What is the Big Bang Theory and how does it explain the origin of the universe?

    -The Big Bang Theory posits that the universe began as an infinitely small, dense, and hot point known as a singularity, which expanded in an outburst of energy and matter, creating everything we see now.

  • What was Alan Guth's contribution to the understanding of the universe's origin?

    -Alan Guth proposed the theory of inflation, suggesting that there was a force before the Big Bang that accelerated its expansion, distributing matter evenly and instantly in space.

  • How does the distribution of matter in the universe relate to the Big Bang Theory?

    -According to the Big Bang Theory, the distribution of matter should be uneven, but Guth's inflation theory explains why it appears even and proportional.

  • What is the concept of Cosmic Singularity?

    -Cosmic Singularity refers to the state of the universe before the Big Bang, where it was infinitely small, dense, and hot.

  • What is Martin Bojowald's view on the origin of the universe?

    -Martin Bojowald suggests that the universe was not born from a singularity out of nowhere but is part of a cyclical process where each universe's beginning is the end of the previous one.

  • What is the concept of quantum time as opposed to classical time?

    -Quantum time is not continuous like classical time; it is composed of small segments with short pauses, similar to the second hand of a clock.

  • What is the cyclic model of the universe proposed by Bojowald?

    -Bojowald's cyclic model suggests that our universe is not the first and not the last, with millions of similar universes existing before and after us in a cycle of rebirths.

  • What is the ekpyrotic model of the universe proposed by Neil Turok and Paul Steinhardt?

    -The ekpyrotic model proposes that our universe is one of an infinite number of parallel universes, all located within a 'brane' or membrane, and that they originate through brane collisions.

  • How do brane collisions relate to the creation of universes according to Turok and Steinhardt?

    -In the ekpyrotic model, brane collisions create two big bangs and two parallel universes, which then move away from each other, continuing their existence until they collide again, creating new universes.

  • What are the implications of the ekpyrotic model for the understanding of dark energy?

    -The ekpyrotic model suggests that the mysterious energy that accelerated the Big Bang could be explained by the collision of our universe with another, providing a potential explanation for dark energy.

🌌 The Birth of the Universe and the Big Bang Theory

This paragraph discusses the origins of the universe, starting with the pivotal contributions of Edwin Hubble. Hubble's observations from Mount Wilson in California revealed that distant gas clouds were actually other galaxies, suggesting the universe is vast and expanding. This expansion implied a beginning, leading to the development of the Big Bang Theory. The theory describes the universe's birth from a singularity, an infinitely small, dense, and hot state that eventually exploded, creating time, space, and matter. The paragraph also touches on the formation of cosmic particles and the evolution into stars and galaxies approximately 12 to 14 billion years ago.

05:00

🔍 Theories Beyond the Big Bang

The second paragraph delves into alternative theories to the Big Bang. Alan Guth's inflation theory addresses inconsistencies in the distribution of matter post-Big Bang, proposing a force that evenly distributed matter in space before the explosion. Martin Bojowald's theory suggests that the universe's birth and death are cyclical, with our universe being neither the first nor the last. Neil Turok and Paul Steinhardt propose that our universe is one of many, existing within a 'brane' or membrane, and that universes are born from collisions between these branes. These theories, while complex and not yet proven, challenge our understanding of the cosmos and its origins.

Keywords

💡Universe

The universe refers to the totality of space, matter, time, energy, and all the phenomena that exist within it. In the video, the universe is portrayed as having a birth and potential previous states, which is the central theme of the discussion. The script explores how Edwin Hubble's observations led to the understanding that the universe is expanding, suggesting it had a beginning.

💡Edwin Hubble

Edwin Hubble was an American astronomer who provided substantial evidence for the expansion of the universe. The script mentions him as a pivotal figure whose observations of galaxies moving away from each other led to the Big Bang Theory. His work is foundational to modern cosmology.

💡Big Bang Theory

The Big Bang Theory is the prevailing cosmological model that suggests the universe began as a singularity and expanded from an extremely hot and dense state. The script describes this theory as a comprehensive explanation of the origin of the universe, although it also points out some of its perceived flaws.

💡Cosmic Singularity

Cosmic Singularity refers to the state of the universe before the Big Bang, where it was infinitely small, dense, and hot. The script uses the concept to illustrate the conditions that led to the Big Bang and to question what could have existed before this state.

💡Inflation

Inflation is a theory proposed by Alan Guth that suggests a rapid exponential expansion of the universe during a very early stage of its development. The script explains how this theory addresses inconsistencies in the distribution of matter in the universe post-Big Bang.

💡Quantum Time

Quantum Time, as discussed in the script, refers to the concept that time may not flow continuously but instead is made up of discrete segments. This idea is used to challenge the traditional understanding of time and to propose that the universe may cycle through Big Bangs and contractions.

💡Cyclic Universe Theory

The Cyclic Universe Theory suggests that the universe undergoes endless cycles of expansion and contraction. The script uses this theory to propose that our universe is not the first and that there have been and will be many others, each with its own Big Bang.

💡String Theory

String Theory is a theoretical framework in which the point-like particles of particle physics are replaced by one-dimensional objects called strings. The script mentions this theory in the context of explaining the nature of parallel universes and the structure of the universe.

💡M-Theory

M-Theory is a theoretical physics model that unifies the five consistent versions of superstring theory. The script refers to M-Theory as a basis for the concept that our universe might be one of many within a higher-dimensional space.

💡Multiverse

The Multiverse is a hypothetical group of multiple universes, including the one we inhabit. The script discusses the idea that our universe might be just one of an infinite number of universes, each possibly with different physical laws and properties.

💡Cosmological Constant

The Cosmological Constant, introduced by Albert Einstein, is a term in the Einstein field equations of general relativity that represents the energy density of empty space, or vacuum. The script mentions it in relation to the mysterious energy that may have accelerated the Big Bang.

Highlights

Edwin Hubble discovered that galaxies are moving away from each other, implying the universe is expanding.

The Big Bang Theory suggests the universe began from a singularity, a small, dense, and hot state.

Alan Guth proposed the Inflation Theory to explain the even distribution of matter in the universe.

Inflation Theory posits a force that accelerated the Big Bang, distributing matter evenly and instantly.

Martin Bojowald suggests that our universe is not the first and that there have been countless others.

Bojowald's theory implies a cyclical universe where each Big Bang is the end of the previous universe.

Neil Turok and Paul Steinhardt propose a multiverse theory where our universe is part of a cycle of rebirths.

The multiverse theory suggests our universe is located inside a brane, a kind of elastic surface.

Universes in this theory can collide, creating two Big Bangs and two parallel universes.

The idea of brane collisions could explain the mysterious energy that accelerated the Big Bang.

The multiverse theory is based on string theory and M Theory, which are central to quantum mechanics.

Turok and Steinhardt's theory requires thinking in 11 dimensions, challenging the limits of the human mind.

The struggle and fear of change are barriers to accepting new scientific theories, such as the Earth being round or the Big Bang.

Currently, there is no evidence to definitively support any of the three major theories about the universe's origin.

The search for the truth about the universe's origin is ongoing, with the hope of finding definitive evidence in the future.

Theories about the universe's origin are crucial for understanding our existence and the nature of reality.

play00:03

how was our universe born and if this

play00:06

seems hard to answer then how about this

play00:09

what was before our

play00:11

universe while scientists are looking

play00:13

for the answer to the most difficult

play00:15

question in history let's find out what

play00:17

they've come up with so

play00:22

far in the 20th century we've shed the

play00:25

light on this mystery all thanks to this

play00:27

man Edwin Hubble

play00:30

one day on Mount Wilson in Southern

play00:32

California he aimed his telescope at the

play00:35

sky and found out that these random

play00:37

clouds of gas flying everywhere are

play00:39

actually other galaxies and there are a

play00:43

lot of them and also he learned

play00:45

something else something that changed

play00:47

the world forever they're

play00:51

moving so what you may ask well it meant

play00:55

one very important thing the universe is

play00:57

expanding and if it's expanding then it

play01:00

probably had a beginning somewhere right

play01:03

now all we have to do is run time

play01:06

backwards and see where the beginning

play01:09

was it took the scientists many more

play01:12

years to come up with a full-fledged

play01:13

Theory The Big Bang Theory and here it

play01:17

is nothing has ever been anywhere

play01:20

because neither when nor where existed

play01:23

do you get it but actually no there was

play01:27

one thing it was the so-called CA mic

play01:30

Singularity a state of our universe in

play01:33

which it was incredibly small dense and

play01:36

very hot imagine if our universe was

play01:39

compressed into a small

play01:42

ball the pressure and temperature inside

play01:45

would be enormous at some point it

play01:47

became impossible to withstand them and

play01:50

here comes the Big Bang it was an

play01:53

outburst of energy and matter that

play01:56

created everything we see now time and

play01:59

space

play02:00

basic physical forces it also scattered

play02:03

quirks

play02:04

everywhere these corks tiny particles

play02:07

that make up our world were all boiling

play02:10

in an incredibly hot Cosmic

play02:12

broth when it cooled down gravity began

play02:16

to attract them to each other they

play02:18

gathered into atoms then molecules and

play02:20

then into the first objects into the

play02:23

world stars and all this happened just

play02:26

some 12 to 14 billion years ago

play02:30

all right now we know how our universe

play02:33

was created but what was before

play02:36

that Alan Harvey Guth an American

play02:39

theoretical physicist and cosmologist

play02:42

has devoted his whole life to solving

play02:44

this mystery after learning about the

play02:47

Big Bang Theory Guth found some flaws in

play02:49

it for example the distribution of

play02:52

matter was very even although it

play02:54

shouldn't have

play02:56

been let's hang a balloon filled with

play02:58

paint to the ceiling and lay a white

play03:01

canvas on the floor if we drop the

play03:03

balloon down it will burst and we'll see

play03:06

absolute Chaos on the canvas a bunch of

play03:09

spots scattered everywhere randomly

play03:12

neither is like the

play03:13

other but that's not really what the

play03:16

universe looked like instead of throwing

play03:18

a colored ball from the ceiling let's

play03:20

draw a small red dot on the

play03:23

canvas now let's expand it a little more

play03:27

and more and capture this all on frame

play03:30

by frame shooting we'll see a circle

play03:32

gradually growing in all

play03:35

directions that's the reality the early

play03:38

Universe was very even and proportional

play03:41

that was guth's Discovery the theory of

play03:44

inflation here's what it says even

play03:47

before the Big Bang there was some kind

play03:49

of force that could give the bang a

play03:52

strong acceleration something that was

play03:54

able to distribute everything in space

play03:57

instantly and evenly

play03:59

guth's theory was a success and now most

play04:02

scientists rely on it for most of them

play04:05

this idea of the birth of the universe

play04:07

is quite enough for most but not for

play04:12

all Martin bojowald is a German

play04:14

professor of physics and in his opinion

play04:17

the universe was born quite differently

play04:20

remember when we talked about Cosmic

play04:22

Singularity the state of the universe in

play04:24

which it was small infinitely dense and

play04:27

super hot according according to

play04:30

Martin's Theory The Singularity couldn't

play04:32

just appear out of nowhere this is

play04:34

nonsense but then where did it come

play04:37

from let's look at a pendulum on an old

play04:40

clock the pendulum rotates back and

play04:43

forth its movement is smooth continuous

play04:46

and non-stop this is how we usually see

play04:49

time it flows and never

play04:52

stops but Quantum time ho ho Quantum

play04:56

time doesn't work that way it's more

play04:58

like the second hand of a clock

play05:00

it consists of small segments and makes

play05:02

short pauses and just like with the

play05:05

second hand of a clock the beginning of

play05:08

one segment of time is always the end of

play05:10

another see what I'm getting at let's go

play05:13

back to balloons again according to the

play05:16

Big Bang Theory Once Upon a Time our

play05:18

universe began to expand inflate like a

play05:21

balloon but sooner or later it will blow

play05:24

away back the universe will start

play05:27

shrinking and return to the state of

play05:29

Cosmic

play05:30

Singularity and then guess what the big

play05:34

bang too nothing appears out of nowhere

play05:37

and disappears into nowhere according to

play05:40

boj wald's Theory the beginning of each

play05:42

universe is the end of the previous one

play05:46

our universe is not at all the first and

play05:48

not the last millions of similar

play05:51

universes existed before us and will

play05:53

exist after

play05:55

us this Theory although it sounds very

play05:58

logical is far far from complete

play06:00

unfortunately we don't have enough

play06:02

knowledge to find all the evidence for

play06:04

it so for now all this is just a

play06:08

hypothesis but some people come up with

play06:10

even stranger ideas scientists promote

play06:13

such unusual theories that no one could

play06:15

even think

play06:17

of Neil Turk a South African physicist

play06:21

and his colleague Paul steinhardt an

play06:23

American theoretical physicist look for

play06:25

answers far beyond our

play06:28

universe they say that yes our universe

play06:31

isn't the first one there have been and

play06:33

will be an infinite number of them and

play06:36

not only will there be endless Big Bangs

play06:39

our universe is just one of an infinite

play06:41

number of others and all of us are stuck

play06:44

in a cycle of endless rebirths of

play06:47

parallel worlds this sounds incredible

play06:50

and frightening at the same time but how

play06:52

does it

play06:54

work according to this Theory our

play06:56

universe is located inside a so-called

play06:59

brain as in membrane in other words

play07:02

we're stuck in some kind of elastic

play07:04

surface that's capable of Contracting

play07:07

stretching oscillating and so on like

play07:10

pieces of fabric on a rope these

play07:12

parallel universes are located near each

play07:14

other each one has a neighbor we're not

play07:17

the

play07:18

exception another universe may be an

play07:21

inch from ours but we can't see it

play07:23

that's because there's a tiny space

play07:25

between us and this tiny space contains

play07:28

the fourth dimension

play07:30

how do these universes originate through

play07:32

brain Collision these brains are getting

play07:35

closer to each other very very slowly

play07:38

until one day they finally Collide their

play07:42

Collision creates two big bangs and two

play07:45

parallel

play07:46

universes then they're moving away from

play07:49

each other the created worlds continue

play07:51

to live we're currently at this stage

play07:54

but when they disappear the brains

play07:56

Collide again and this will lead to the

play07:58

birth of a new

play08:00

universe remember the inflation Theory

play08:03

there was a mysterious energy that

play08:05

pushed and accelerated the Big Bang well

play08:07

if we did Collide With Another Universe

play08:10

that would explain

play08:11

everything of course everything

play08:13

described here is a great simplification

play08:16

when you hear that our world is some

play08:18

piece of fabric on a rob it sounds like

play08:20

complete nonsense but this idea is based

play08:23

on string theory and M Theory two giants

play08:26

of quantum mechanics if they turn note

play08:29

to be true they could explain almost

play08:32

everything in our

play08:35

universe creating a theory is an

play08:37

incredibly huge process Turk and

play08:39

steinhardt made a huge amount of

play08:41

calculations and swept away many many

play08:44

non-working

play08:46

theories also to work this out they have

play08:49

to overcome the limits of the human mind

play08:51

and think in 11 Dimensions at once

play08:54

unfortunately this crazy and elegant

play08:57

idea was laughed at

play09:00

turro and steinhardt say that scientists

play09:02

are regular people just like everyone

play09:04

else they're also afraid of change and

play09:07

the unknown and it's really scary to

play09:09

question everything we once believed in

play09:13

many years ago people didn't believe

play09:14

that the Earth was round then they were

play09:17

outraged by The Big Bang Theory we can't

play09:19

make discoveries without struggle and

play09:22

fear that's why Turk and steinhardt

play09:25

don't plan to give up so easily after

play09:27

all the evidence that we have now only

play09:29

says that each of the three theories is

play09:32

equally possible so which answer is

play09:34

correct we may never know at least not

play09:37

at this stage of human development

play09:39

unfortunately as long as we have no

play09:41

evidence we can only theorize but maybe

play09:45

one day we'll find something that will

play09:46

open our eyes once and for all maybe one

play09:49

day we'll solve the mystery of how our

play09:51

universe came to be

play10:00

that's it for today so hey if you
