they asked him
looking at the starry sky how
far these are those stars that
we see at night or the moon they asked
how far is it or how big is it
the moon or the sun’s day they asked
sometime how far is the sun or
what is the actual size of the sun
they are questions that are quite difficult
to respond
we know that we live on a planet that
along with seven other planets more shape
our solar system
our solar system in turn belongs
to a galaxy our sun is a
star and is one more than another 400 thousand
millions of stars that there are in the
Galaxy as 400 billion
stars and in turn our galaxy is
one more than another 100 billion
galaxies in the universe and already as well
it says a lot of numbers and it’s already
difficult to understand these numbers so
large is very difficult to size what
our is not full of these
gigantic amounts and it is very difficult
of understanding we only provoke them
with our with our neighborhood
cosmic
let’s just stay with our
solar system and we will try to
size and understand the distances and
the sizes of our solar system
and what better for this is used a
scale and how a scale is making a
scale is to take an object from which
let’s know its real size more or less and
replace it in this case for a
body of the solar system and have by
example if I tell you the statue of the
freedom
he who does not know her surely a
image
a movie or on television and he knows
I’m talking about a large river object
big compared to the stature of
a human being I do not tell you that the
Liberty stature is a monument that
is in new york on an island and has
more or less 93 meters high
let’s start here and let’s realize that
we put the sun there in new york in that
island where is the statue of the
freedom and of that size to find
the earth we are going to have to move away 10
kilometers of the island where is the
freedom statue and more or less so that
Meet New York to see what 10
miles
we are located or less in the central park
let’s do this with another city let’s
Europe surely some of you
abhisit europe and if they were in europe
You have probably visited Rome and
yes they were in Rome the destination
bound is the coliseum the same the
Coliseum is an oval that more or less than
Largest diameter is 150 meters
right now let’s put in alone and in the
roma and we start from there
size of the coliseum and now we’re going to
find that the earth is going to be
further and to meet with
our planet
we’re going to have to go 16 kilometers from
distance that will take us to the
outskirts of rome
will take us to the city of frascati
and since we are in Europe
let’s do one last exercise I imagine
also that those who were in
Europe must have visited Paris and if
they had in paris
surely they know the eiffel tower or the
Date tower is bigger than the others
two that we saw previously already has 324
meters high to oneself
imagine the sun placed there in the
Paris center the size of the tower
eiffel draw the earth will be very
far away the earth will be at 34
kilometers away in france this
takes us to the city led course and does not
they ask
Where will Pluto be where the
solar system where are the confines of
our solar system with use of size
of the eiffel tower and located in the
center of paris fruits no longer even
is in France to find soon what
we are going to have to go and look for a thousand 360
kilometers away in spain
more or less in the city of Seville there
there will be a little ball
‘I would be prudhomme so I want them
say that I want to show with this that
solar system is not all crowded everything
Together as well in the first image
it’s not solar system is very extensive
the distances between planets
they are colossal are unimaginable
it’s all too far far away but
what do you think if this exercise of
scales that we did in other cities already
We have here and we do it at sea
silver
we make more local and we explore our
Solar system
the sea of silver for those
surely they are not marplatenses
discount that mar del plata is a
coastal city that has if we measure it
in a straight line along the coast more or less
17 kilometers and if we measure it from the
Coast inward
I say the coast to the west has
about 10 kilometers
I mean roughly the urban area
would those measures
we are going to use those measures for our
scale and we will do as we did with
the other cities and we’re going to take a
historic monument to boot from there
and put soleil and if I have them
I ask you where it is used to
moses the marplatenses every four years
when Argentina won a match in the
world where we met where
we’re doing pretty well
we used to meet in the
Monument of San Martin and Miter Rubicam
for those who are not from Mar del Plata
He commented that the monument of San Martin
it has a more or less height that goes
from the cord to the head of
general sanz
It is 14 meters high and is located
in the micro center of our city
if there is in the corner of luro and miter
well let’s imagine there let’s imagine the sun
there and that size the size of
monument of san martin and from
there we start with the scale and we are going to
realize that the first planet
mercury the smallest planet is going to
be the size of a golf ball and
will be 600 meters away from the
Monument of San Martin
Little boy imagine a golf ball
next to the monument of san martín the
second planet venus
– it will be further away until a
kilometer and it’s going to be more or less than
size of an apple but what’s important
it is the land where the earth will be
and what size will the land be with
a sun of 14 meters high
the moment of his death in our
land is going to be only the
size of a grapefruit
imagine a grapefruit next to the monument
de san martín is very tiny very
tiny compared to the sun and where it goes
to be up to a mile and a half or 15
blocks
if they want yes if we take from uribism and
we go down the avenue luro
these 15 blocks are going to reach us
corner of Luro and pampa where there is
the ferroautomotor imagine in the struggle
a grapefruit
good that land turning around the
monument of san martín but yesterday not
she is alone because we are at night
when we go out and look at the sky
moon and we think it is not taken
because it ‘s big and it’s close
I will not tell you that on our scale the moon
It is the size of a walnut and is located
4 meters grapefruit and here are two
Important points to keep in mind
the first point is that that distance
vigon the earth moon distance is the
greater distance than until now
turned to a man I say man
as a species throughout its history
he went further from the earth
those four meters that there is of the grapefruit to
the nut or what’s going to be pretty
difficult that in the near future
let’s get to explore other
planets of the solar system said so
articulated not the planets of the system
solar because imagine if it cost us
I work to travel those four meters that
there’s earth to the moon we’re going to
cost a lot more work to travel
the hundreds of meters that separate us from
the planets closest to the system
solar and the second point that does not mean
it is no less important than
first is that already knowing that the size
of the moon equals one is no longer
we are ready for when you are
unbearable girlfriends
they ask us to give them the moon
well we know that between Antonio narro
is that we are going to be fulfilling your
order
that yes in advance with ending the one
we are working in a house can be
one trick the door in the face and we
We are going to be without a girlfriend
possibly but good, let’s continue
with this walk through the solar system
the next planet that comes on Mars
sure we left the monument of san
martín or tuesday goes up to two
kilometers to be the size
of a tennis ball smaller than the
land between Mars and Jupiter is the
asteroid belt that our
scale and if we continue along the avenue luro
It will be located between the avenue
Champagne and arturo avenue there
imagine there are going to be hundreds of thousands of
very small particles swarming
around the monument very small I say
imagine ten times smaller than
the grains that make up the sand more than
30,000 would of those those would be the
asteroids after jupiter
the gas giant the biggest planet
of our solar system
this one that leaves little ones to all
other planets in our face is going to be
a ball of one and a half meters and goes to
be located you remember when you
I counted that sea of silver from the coast
for inside it has ten kilometers of
more or less good urban center but
untill there
in the limit to 9 and a half kilometers there
where the avenue luro ends and it begins
Route 226
good imagine a ball of a meter and
medium is Jupiter and from there
that the distances are going to be every time
bigger and they’re almost going to double and
to find the next planet
saturn the planet of the rings
we’re going to have to travel more and we’re going to
have we saw 14 kilometers from
distance
thus starting from the monument to the general
san martín a hot and miter 14
kilometers distance will take us more
or less at the entrance of the Laguna de los
parents
there will be Saturn and what size
of saturn or so make a ball
95 centimeters high so that it
give an idea the equivalent of the wheel
of a truck or a collective
so imagine the wheel of a
collective at the door of the lagoon
Saturn’s parents and the last of
planet that we are left only in tuna or
that are very similar to each other in
sizes and since we’re talking about
wheels I will tell you that they are the size of the
wheel a car were going to be located
neptune 29 kilometers away
I say following the route 226 no
natural 45 kilometers away
and all this back do not ask
where do they end solar system where is
pluton that beyond that is no longer a
planet does not matter how equal success
because it will give us an idea of which
are the confines of our system
solar with a sun the size of
monument of san martin put the gold and
miter brute is going to be very small pluton
spend nothing more than the size of a
coin
imagine a coin next to the
monument of san martin and where is it going to
be located to be located at 65
kilometers of distance
there at the entrance to the city of
balcarce imagine a coin in the
ground for that python spinning around
from the monument of san martín to heat and
miter
and so we could continue we could continue
placing the stars
close is that at night when we left
we look and ask ourselves where are they
those little dots of light where the cross is
from the south
the three marias but we are going to give
mind that the distances are so
great so colossal that it’s the same
surface of the earth I would stay
girl to continue with this scale and
place the stars in the back line
the planets
so good that I wanted to tell you only
with all this
those starry nights that night of
summer we went outside to look at the
stars and how beautiful we fall into
head
remember first you can give him the
moon to his girlfriend because they give him a new
and ready
but do not forget do not forget that
we only live in a grapefruit lost in the
immensity of space
thank you very much
[Applause]
