well guys, I would like to start
Today’s lecture
talking a little about a story one
history that already occurs there are 13 points 7
billions of years
in this story I and each one of you
we participate as actors in
with various natural processes in our
environment here on earth but at the
time but we are also mere
spectators
observing several processes also
occurring in the interstellar medium occurring
this vastness of the cosmos around us
this duality seems intrinsic to us
human beings not only that but also
another feature that
attention that curiosity
maybe we all have
intrinsically the curiosity and
curiosity was what motivated me
from childhood to being a scientist I
basically did not know if I would be physical
mathematician or astronomer
but I was sure that I wanted to be
scientist and in this history of being
curiosity scientist
I stared at the stars and spoke
chancer that exists somewhere
other person some other living being who
Are you thinking the same thing as me?
if there is a possibility of life in
other planet than the one I
I’m living well, this child has grown
today becomes the scientist works with
astrobiology astrobiology
ironically when I’m going to talk to
My friends, they speak today, you tax.
work with astrobiology you should
be looking for some kind of
little green man out there people
astrobiology is not to seek a little man
green and I do not even make contacts with this type
to be when I spoke to my parents
I would work with astrobiology and
they say you may have been misrepresented
due to watch movies very much
star trek star wars saifi movies more
astrobiology is not
linked to star wars mec
society itself knows then that the
astrobiology would have much to do with
astrology
hey is all about astrobiology is the
study of life is the influence of the stars
in our life
We, too, have no astrobiology.
nothing to do with astrology
in fact astrobiology is precisely
which I can summarize in three drawings
which is an area that worries and tries
understand issues related to the origin
the evolution and distribution of the
life in the universe through a
conception and a cosmic vision of
this process of evolutionary existence and
possibility of us finding lives
in another place without being here on earth as well
talking about astrobiology surveys
can be worked from a
multidisciplinary way to astrobiology
a multidisciplinary area
so we can work relationship one
research related to exoplanets that
are planets orbiting other stars
without being our sun
We can do research. We’ll try.
has adequate environmental conditions
for the existence of life as per
example if there is liquid water in
surface
if on any planet if there is
water surface water
it’s a great possibility that we
to find life on these planets beyond
of this we generally seek such a life
as we know it here on earth and
some time ago we went
surprised as living beings of
a form a little different from us who
are called extremophiles the bacteria
extremities and conditions that are
completely new clues for us
so they can survive in
conditions that have a high radiation rate
high temperature temperature
very low temperatures
that is all that would be harmful
for life as we know it
for us humans they live and
they survive quietly
another point I would like to talk about
on astrobiology is the research that I
I work with meteorites
I do meteorite analysis between the
meteorites that work is a meteorite
a meteorite nw at 69 63 and in the
my research on uerj
along with the staff of the laboratory eta
collaborating with the staff of the
df rj from coppe we did a picture of
micro- image that the image that you
are now seeing friend tomography
a non-destructive technique ie we
we did not need to destroy
the meteorite it remains intact with
all your information
and it was this
structure that we find that
unlike what usually people
found in meteorites
it has a very peculiar structure one
training that is sometimes even confused
with several things we could do
analogy with what we know here
in the land
this brings information related to
possibility of existence of life in
Mars or even the possibility of
to find out what kind of evidence
of water on Mars but before speaking
about life
obviously we need to talk about the
existence of something else because if you
want to know about the origin of life or how
she developed life distribution
in the universe as calcei would not speak
if you want to make an apple pie
you need to make the
universe is created and how the
universe came to be well
the event we call the beginning of the
universe is the big ben with the passing of
time after the big ben in small
particles were created as electrons
neutrons which, when passing from the
time they were also joining
informing the first atoms as the
hydrogen atoms and helium atoms and
with that time passed and the
first generations of galaxies
were formed more clearly the cycle of
The life of these stars comes to an end
at some point and when it happens
we have what there is
people can see through this image is
injection of material in the
interstellar
this material is composed of several
types of acts as carbon atoms
hydrogen atoms oxygen nitrogen
phosphorus and these atoms that are forged
inside the cauldrons of these
stars are the same acts that make up
living matter atoms that make up
molecules and cells of living beings
so I could say that we are
dust of the stars we are originally we are
made of dust from the stars because they are
the same acts done on the stars
and when I talk about it, this is
connected to the so-called core syntheses
outer peace die
they are already not only this material with
of this material other stars are
existence and also the possibility of
outer planets have going
in future, having conditions or
not to shelter life then life can
come what draws attention not
necessarily life is that this
life will also be a smart life
are completely different things
so when I talk about possibility
existence and if there is so much
chemical abundance of the universe is
recycling at all times
Obviously we can not afford to
ask how at the time that I was
child will be that with so much condition of
existence of life will be that we
we are really alone in the universe
but the question remains where is everything
world that until now we have not detected beings
intelligent and have the technology to
be detected or contacted
with them many different explanations
we can give one of them for example here
can there really be civilizations
developed with technology for people
to detect and also communicate
but perhaps civilizations are only
into the universe in such a way as to be
so small a proportion that it would be
to detect a needle in a cosmic haystack
there is also another possibility of
that the life time of these civilizations
with so advanced technology can be
extremely short
sometimes we do not have the possibility
send a man to mars and return with
safe life they leave send
any kind of living being out of the
solar system
yet we are already destroying us
little by little to the people doing with
that several species are extinct
We are clearing several forests.
increasing global warming
quickly and not only this
we are also creating diverse
types of armaments that could
simply extinguish all our
humanity and also several other
species
then based on the parameters of nodes
same here on earth may be that before
even we have a technology
sufficient to be able to detect or
communicate with other intelligent beings
we can also do as we
to destroy
well before that but also has a
third case that would be a bit more
optimistic, civilizations can
have simply transcended all
this barrier not only only barriers
religious policies and others but also
barriers in technological development
in such a way that technology would be so
advanced that we even trying to find
information and detect these
civilizations we do not have technology
sufficient to detect or receive
this informations
our technology could simply
extremely primitive in relation to
these submissions of information that they
are perhaps also sending people
can think of a more realistic or way
or more pessimistic who has nothing
for us to look for we are
looking for something that does not exist
we are the only beings in the universe
we will be alone we have soy in the
of the universe well independent of us
we are the only ones or there are several
civilizations in the interstellar medium by
universe with a huge amount of
civilization
I would like to draw your attention to
this place
although we have evolved the whole
our technology so we
we can detect several
planets
the land is the only place we have to
certainty that shelters life
all the people you know all
the information that you
from prehistory to the days of
Current anything you’ve ever heard of
the whole story of the universe that
we know where living things
began to exist and to exchange
information is here
so I would like to say that despite
we have all this apparatus feel we
we were able to find several others
planets with the conditions of
possible environment in which we could
find life or even in the future
we find planets that are the
places that we could have
Entirely interesting for us
we survived and we still did not live
enough technology to get out of the
earth and inhabit the planet like panties
I would say there are several planets that
may even have conditions for life
there are conditions for us to
Let ‘s fight, but we do not have
still technology or maybe
in the future we could house these
planets not so soon maybe we
could visit but could not
because of this I would like to call the
attention that although we found
various planets of the solar system and
outside the solar system
the land remains one place
not only that it shelters life but that we
we can live
the land is our home, thank you personally
[Applause]
