Did The Past Really Happen? | Karan Ahuja | TEDxYouth@HCIS


good morning everyone and today I’m here

good morning everyone and today I’m here to talk about the topic did the past

to talk about the topic did the past

to talk about the topic did the past really happen so I just like to start of

really happen so I just like to start of

really happen so I just like to start of this talk with what we know about the

this talk with what we know about the

this talk with what we know about the past so can someone named me the two

past so can someone named me the two

past so can someone named me the two buildings shown here are the lady there

buildings shown here are the lady there

buildings shown here are the lady there okay can someone else name me the other

okay can someone else name me the other

okay can someone else name me the other building yes okay correct

building yes okay correct

building yes okay correct so um there are some history phonetics

so um there are some history phonetics

so um there are some history phonetics in this audience but does anyone know

in this audience but does anyone know

in this audience but does anyone know when the Leaning Tower of Pisa was built

when the Leaning Tower of Pisa was built

when the Leaning Tower of Pisa was built okay never mind it was actually its

okay never mind it was actually its

okay never mind it was actually its construction site in one one seven zero

construction site in one one seven zero

construction site in one one seven zero and it astonishingly only side to lean

and it astonishingly only side to lean

and it astonishingly only side to lean in one and seventy five do to one side

in one and seventy five do to one side

in one and seventy five do to one side of the tower sinking in soft sand so

of the tower sinking in soft sand so

of the tower sinking in soft sand so this was just to get the presentation

this was just to get the presentation

this was just to get the presentation flowing the question that can be asked

flowing the question that can be asked

flowing the question that can be asked about this is how do we know it was

about this is how do we know it was

about this is how do we know it was built in one on seven zero inside

built in one on seven zero inside

built in one on seven zero inside leaning on one one seven five well is

leaning on one one seven five well is

leaning on one one seven five well is there a way of proving this one could

there a way of proving this one could

there a way of proving this one could argue that some books or some reliable

argue that some books or some reliable

argue that some books or some reliable sources mentioned there was created

sources mentioned there was created

sources mentioned there was created during this period however how do we

during this period however how do we

during this period however how do we know that those books or those websites

know that those books or those websites

know that those books or those websites are not lying one cannot simply put a

are not lying one cannot simply put a

are not lying one cannot simply put a gun to the author’s head and ask him

gun to the author’s head and ask him

gun to the author’s head and ask him whether he’s one of the very good

whether he’s one of the very good

whether he’s one of the very good examples of the idea that I’m trying to

examples of the idea that I’m trying to

examples of the idea that I’m trying to bring bring across here is a book 1984

bring bring across here is a book 1984

bring bring across here is a book 1984 so for people who haven’t read it

so for people who haven’t read it

so for people who haven’t read it basically in it the government

basically in it the government

basically in it the government manipulates history in a way that suits

manipulates history in a way that suits

manipulates history in a way that suits them so how do we know that the

them so how do we know that the

them so how do we know that the government or anyone rather hasn’t

government or anyone rather hasn’t

government or anyone rather hasn’t manipulated with history in a way that

manipulated with history in a way that

manipulated with history in a way that suits them oh yeah and the Leaning Tower

suits them oh yeah and the Leaning Tower

suits them oh yeah and the Leaning Tower of Pisa was actually built in one on 73

of Pisa was actually built in one on 73

of Pisa was actually built in one on 73 and side leaning and one on 7/8 see how

and side leaning and one on 7/8 see how

and side leaning and one on 7/8 see how easily I lied to you but you believe me

easily I lied to you but you believe me

easily I lied to you but you believe me this clearly proves the point that I’m

this clearly proves the point that I’m

this clearly proves the point that I’m trying to establish here which is that

trying to establish here which is that

trying to establish here which is that how do we know that the that anyone has

how do we know that the that anyone has

how do we know that the that anyone has been manipulated with history and

been manipulated with history and

been manipulated with history and presented to it to us but a bigger

presented to it to us but a bigger

presented to it to us but a bigger question that can be asked about all

question that can be asked about all

question that can be asked about all this is that how do we know that all

this is that how do we know that all

this is that how do we know that all this happy

this happy

this happy and not in a specific way but at all how

and not in a specific way but at all how

and not in a specific way but at all how do we know that all this ever existed or

do we know that all this ever existed or

do we know that all this ever existed or ever happen unfortunately we haven’t

ever happen unfortunately we haven’t

ever happen unfortunately we haven’t invented time machines yet otherwise we

invented time machines yet otherwise we

invented time machines yet otherwise we could have gone and seen for ourselves

could have gone and seen for ourselves

could have gone and seen for ourselves so now how do we tackle this problem

so now how do we tackle this problem

so now how do we tackle this problem with only the resources that we have

with only the resources that we have

with only the resources that we have before I answer this question let’s talk

before I answer this question let’s talk

before I answer this question let’s talk a bit about our future generations so

a bit about our future generations so

a bit about our future generations so yes now there will be the one suffering

yes now there will be the one suffering

yes now there will be the one suffering and wandering in thousand years whether

and wandering in thousand years whether

and wandering in thousand years whether how did they know that a great man

how did they know that a great man

how did they know that a great man really gave a speech on this stage on 7

really gave a speech on this stage on 7

really gave a speech on this stage on 7 April 2017 well they wouldn’t be able to

April 2017 well they wouldn’t be able to

April 2017 well they wouldn’t be able to answer this question

answer this question

answer this question unless obviously if there created time

unless obviously if there created time

unless obviously if there created time machines but no matter how advanced they

machines but no matter how advanced they

machines but no matter how advanced they are or look like this or this

are or look like this or this

are or look like this or this alternatively they won’t be able to

alternatively they won’t be able to

alternatively they won’t be able to answer this question so future

answer this question so future

answer this question so future generations will definitely know less

generations will definitely know less

generations will definitely know less than us about one thing which is right

than us about one thing which is right

than us about one thing which is right now right here today no matter Hamid

now right here today no matter Hamid

now right here today no matter Hamid they try they will not know exactly what

they try they will not know exactly what

they try they will not know exactly what we know about today they won’t know the

we know about today they won’t know the

we know about today they won’t know the actual purpose behind our beliefs one

actual purpose behind our beliefs one

actual purpose behind our beliefs one example of this is the Indian belief of

example of this is the Indian belief of

example of this is the Indian belief of throwing coins in the river the actual

throwing coins in the river the actual

throwing coins in the river the actual purpose of this in the early times was

purpose of this in the early times was

purpose of this in the early times was to purify the water because the coins

to purify the water because the coins

to purify the water because the coins were made of copper the copper caused

were made of copper the copper caused

were made of copper the copper caused the dirty water to stay down so that the

the dirty water to stay down so that the

the dirty water to stay down so that the clean water could be active from above

clean water could be active from above

clean water could be active from above but now the practice still goes on but

but now the practice still goes on but

but now the practice still goes on but the coins are not made of copper anymore

the coins are not made of copper anymore

the coins are not made of copper anymore the practice is still being followed but

the practice is still being followed but

the practice is still being followed but the cause has been lost over the period

the cause has been lost over the period

the cause has been lost over the period of time okay that example was a bit

of time okay that example was a bit

of time okay that example was a bit off-topic but how do we know that the

off-topic but how do we know that the

off-topic but how do we know that the universe wasn’t created last Thursday or

universe wasn’t created last Thursday or

universe wasn’t created last Thursday or even today morning or maybe to be very

even today morning or maybe to be very

even today morning or maybe to be very extreme even a minute ago so I’ll be

extreme even a minute ago so I’ll be

extreme even a minute ago so I’ll be talking about one of the examples of

talking about one of the examples of

talking about one of the examples of this is the argument last Thursday ISM

this is the argument last Thursday ISM

this is the argument last Thursday ISM so last cells ISM states that Laster ISM

so last cells ISM states that Laster ISM

so last cells ISM states that Laster ISM is the idea that the universe was

is the idea that the universe was

is the idea that the universe was created last Thursday but with the

created last Thursday but with the

created last Thursday but with the physical appearance of being billions of

physical appearance of being billions of

physical appearance of being billions of years old

years old

years old under laster’s ISM books fossils light

under laster’s ISM books fossils light

under laster’s ISM books fossils light already on the way from distances and

already on the way from distances and

already on the way from distances and literally everything including a

literally everything including a

literally everything including a memories of the time before last

memories of the time before last

memories of the time before last Thursday were all formed at the time of

Thursday were all formed at the time of

Thursday were all formed at the time of the creation in a state said that they

the creation in a state said that they

the creation in a state said that they appear much older ok let me just

appear much older ok let me just

appear much older ok let me just summarize this for you so that you can

summarize this for you so that you can

summarize this for you so that you can digest this all in quickly so basically

digest this all in quickly so basically

digest this all in quickly so basically the theory argues that the universe is

the theory argues that the universe is

the theory argues that the universe is created last Thursday and all our

created last Thursday and all our

created last Thursday and all our memories just popped into existence ok

memories just popped into existence ok

memories just popped into existence ok so all these structures possibly came

so all these structures possibly came

so all these structures possibly came about last Thursday and it’s just that

about last Thursday and it’s just that

about last Thursday and it’s just that our memories are in such a way that we

our memories are in such a way that we

our memories are in such a way that we think that these were created in years

think that these were created in years

think that these were created in years such as 1 173 this idea was put across

such as 1 173 this idea was put across

such as 1 173 this idea was put across by mr. Bertrand Russell is there anyone

by mr. Bertrand Russell is there anyone

by mr. Bertrand Russell is there anyone in this room that can prove this theory

in this room that can prove this theory

in this room that can prove this theory to be wrong no see this story might not

to be wrong no see this story might not

to be wrong no see this story might not actually be true maybe the universe was

actually be true maybe the universe was

actually be true maybe the universe was really created billions of years ago

really created billions of years ago

really created billions of years ago it’s just that the theory can’t be

it’s just that the theory can’t be

it’s just that the theory can’t be proved wrong and is in falsifiable now

proved wrong and is in falsifiable now

proved wrong and is in falsifiable now let’s go back to our future generations

let’s go back to our future generations

let’s go back to our future generations for a bit so just to recap future

for a bit so just to recap future

for a bit so just to recap future generations will know more than us in

generations will know more than us in

generations will know more than us in the field of science and other subjects

the field of science and other subjects

the field of science and other subjects will not know more than us about today

will not know more than us about today

will not know more than us about today future generations won’t be able to

future generations won’t be able to

future generations won’t be able to experience this feeling that we are

experience this feeling that we are

experience this feeling that we are feeling today which is of excitement

feeling today which is of excitement

feeling today which is of excitement obviously so is there another way that

obviously so is there another way that

obviously so is there another way that future generations will be able to prove

future generations will be able to prove

future generations will be able to prove eye existence yes there is and it’s

eye existence yes there is and it’s

eye existence yes there is and it’s called energy more specifically entropy

called energy more specifically entropy

called energy more specifically entropy so what is entropy entropy is the total

so what is entropy entropy is the total

so what is entropy entropy is the total amount of energy present in the universe

amount of energy present in the universe

amount of energy present in the universe that can’t be converted to any other

that can’t be converted to any other

that can’t be converted to any other form of energy basically in simple

form of energy basically in simple

form of energy basically in simple layman terms use less energy so why is

layman terms use less energy so why is

layman terms use less energy so why is this energy useless because it can’t be

this energy useless because it can’t be

this energy useless because it can’t be converted to any other form of energy

converted to any other form of energy

converted to any other form of energy therefore it can’t be used so the second

therefore it can’t be used so the second

therefore it can’t be used so the second law of thermodynamics states that

law of thermodynamics states that

law of thermodynamics states that entropy always increases with time

entropy always increases with time

entropy always increases with time therefore future generations and us too

therefore future generations and us too

therefore future generations and us too honestly can make use of this law to

honestly can make use of this law to

honestly can make use of this law to prove the past existence because if the

prove the past existence because if the

prove the past existence because if the past do not exists no entropy should be

past do not exists no entropy should be

past do not exists no entropy should be present because entropy increases by a

present because entropy increases by a

present because entropy increases by a small amount every time an energy

small amount every time an energy

small amount every time an energy transformation takes place an increasing

transformation takes place an increasing

transformation takes place an increasing amount of entropy will lead to the

amount of entropy will lead to the

amount of entropy will lead to the death of the universe the heat death of

death of the universe the heat death of

death of the universe the heat death of the universe would be at the point that

the universe would be at the point that

the universe would be at the point that no work could be done because all the

no work could be done because all the

no work could be done because all the energy has become entropy and has

energy has become entropy and has

energy has become entropy and has basically become useless so lazy people

basically become useless so lazy people

basically become useless so lazy people actually in some way considerate and try

actually in some way considerate and try

actually in some way considerate and try to postpone the heat death of the

to postpone the heat death of the

to postpone the heat death of the universe because they make less energy

universe because they make less energy

universe because they make less energy transformations because they do less

transformations because they do less

transformations because they do less work so whenever someone asks you why

work so whenever someone asks you why

work so whenever someone asks you why you say lazy again you know the answer

you say lazy again you know the answer

you say lazy again you know the answer you’re just trying to postpone the heat

you’re just trying to postpone the heat

you’re just trying to postpone the heat death of the universe so without time

death of the universe so without time

death of the universe so without time machines actually proving the past

machines actually proving the past

machines actually proving the past without time machines can only be done

without time machines can only be done

without time machines can only be done through the use of entropy now you might

through the use of entropy now you might

through the use of entropy now you might be wondering how in the world did he get

be wondering how in the world did he get

be wondering how in the world did he get from did the past really happen to the

from did the past really happen to the

from did the past really happen to the heat death of the universe well I’m

heat death of the universe well I’m

heat death of the universe well I’m still trying to figure that out myself

still trying to figure that out myself

still trying to figure that out myself thank you for listening

thank you for listening

thank you for listening [Applause]
