with me that there are things that are life and
things that are not true
for example this beach tomb
when it’s hot and have a visa
marine take something really being a
bacteria lives in the ocean floor to
Hundreds of degrees with sulfur comfort
burning without light without oxygen
also life a little extreme what
I recognize but of life
however research without funds and
indirect aids
that’s not life but because we’re interested
so marked by that we all have it
very clear what is good and what is
saw clear let’s one thing is to understand
will leave it please plus a survey that
raised your hand and tell me what
you think this is alive, not scary
well very well many people the saga now
that what you think this is alive and
much dialogue the room now a sponge
for those who thought that this is
I live a human virus I see a lot
physical in the room and now what
you think that this is alive, not that I have
life but the clay is alive
it seems that we are less – in agreement
with the virus
with them we have doubted and it is normal
because it’s not clear but why not
so much interested in this definition of life
marked the boundary between the living and the
inert to answer a question
which is actually a path that
we started thousands of years ago and it’s that
question is
we come but we are able to imagine
where do we come from until 1600 and from
anton van leeuwenhoek to be invented and
look for your fantastic microscope
we were unable to imagine what the
microscopic life
we did not know how it was we could
imagine we were linked by the little person
tiny little girl very tiny
we can not imagine the way it would have
in his saying and that he also moved
then it turned out that those little animals
ass was not as small as I could
be alive but we lack imagination
It’s hard to imagine how that life could be
also the little ones so small
despite that simply they are alive
the 1930s passed
the emptiness of English william balfour
He described that viruses should be more
small that the cell smaller than
you could see around here at that time
by the most powerful microscopes but
larger than water molecules
a series of filters one more filter
big one that gave the cells a hundred more
small that gave the infective capacity
and the water however went through so much
the viruses must be something like
a simple little molecules more
Great than water but much more
small than a cell and yet
be alive and be able to transmit
diseases who could imagine something
so simple, despite that, so powerful
and it is that we lack imagination we missed
imagination to imagine life
simple the lack of imagination makes
a little
we think that life on earth
it was also something very limited that
I will give only in a few
zero tolerance margins and we know
that there are bacteria that are capable of
live hundreds of degrees the funds
oceans the yellowstone lagoons
we also know that there are products that
are able to live at very low
temperature and that endures a lot
even pressure and organisms that are
able to live in the plants
nuclear cooling towers
the nuclear power plant are capable of
hold on there just barely discovered
these bugs the most well-known dangers
how to do your own is able to
to live without water for a very long time
that there is no lack of imagination
it turns out that we are very difficult
imagine a life that is not like the
our a life that is not based on
carbon much less a life that does not
have
of course it costs us a lot
imagine that kind of life
but why is it so hard for us to imagine
that life is why this
problem of actually all of life in
the universe we only have one point
only one that we have on earth is a
problem that we only have that point and
we are an isolated point or if
belongs to a set that belongs to
a set we do not know if it is part of
an ascending set defend treaties
no idea what life’s graphic is like
in the universe we do not even know
look, we do not even know where
comes life here on earth life
could arise in the clay
it may be that the pyrite bases
ocean bottoms be the laboratory that
nowadays he continues to give chemical molecules
that gives rise to complexity
we should stop looking for this one and start
to look for brown mucus in March
not only do we have the problem of that
only point in the graph but that
it also turns out that all that life there
on earth it has an origin like
who calls him luca the last ancestor
common to all in relation to vrsaljko
manifest that origin as well as knowing
that there is only this point that
we know, there is not one
reflection and that is to look for the
definition of life only on earth is
a blunder because we do not have
enough data
we have to look outside let’s look
outside you have to vote because I do not know if you
you have big universe of the fuck
we can not search the whole universe what
I feel it would be very easy but we can not
to fall in any case yes we have to
bring looks out of thanks
because it does not make much sense there’s no
many scenarios for life
good at 95% of energy and matter
that the dark matter tour but not the
we know we are not nature nor
we even know international with her
as above to look for live sayings
so let’s have one of the
galaxies in galaxies
there are billions of galaxies by
within the galaxies
if we go to the center of the galaxy they are
very energy zones areas that are
releases such an amount of energy that
it seems unlikely that there could be
life or at least keep it
for a long time
yet we know they are there the
the longest stars in the universe
but let’s go very the periphery is little
metallic there is little material with which
make planets
there are some of course but it seems that
there is little trial for life so we
we are very close and very far from that
center in the habitability zone for
the practice within each of those
galaxies
there are hundreds of billions of
stars and around most of
those stars
it seems that today we have quite clear
that there are planets
some of those planets are in what
it’s called the habitation zone wake
that zone of habitability celap is
define because on its surface it can
have liquid water because water in the
chis universe
a lot but almost everything is frozen
or in the form of a loop and we are very close
of his star
it turns out that the wind of the star
barreda atmosphere and leaves the planet
unprotected but goes very far are
planets very cold and therefore quite
liquid water complicated and therefore
in that area of habitability that where
is the earth there may be liquid water
on its surface
but be careful because that habitability zone
is changing and depends on the star
Thousands of years ago, a billion years ago
the land is outside the zone of
habitability of the sun and between 4,500
millions of years will be out again
yes a civilization and look at the
inland from 4,500 million years
probably meets the
surprise for them us not that
there was never life thinking in 2016
found next time it sounds all true
next time orbits the star more
close to our next centauri sun and
the orbit in its habitability zone
but maybe it’s a little less known
this one rapex system is a star
ultra of nothing very cold that has a
system of seven planets around
which five have a size
intermediate between the earth and Mars and
three of them are in their area
habitability
I’m thinking that that is far away
that will not arrive because we want it
study but it serves this but good
we can study it in the distance
for example we can life markers
biomarkers because of those planets
when a planet passes in front of its
star the light of the rhythm of his star
Mary is modified to modify
analyze the spectrum and know what kind of
gases and at what concentration is that
atmosphere and so we can know if there
a lot of carbon dioxide and
water and CO2 and oxygen although it is not
necessary we can study it but not
we are arriving we do not see it here mouth
we are looking for things that we already know
things that we already know we are looking for
where there is light but we do not look a little
beyond or a little bit higher
I propose by pure utility to look for the
site of the type of music in our
own solar system
for example outside the area of
habitability need this thinking
in March truth of planets like the
earth billions of years ago the
inland of my determined years
I’m not going to prepare other things a little bit
more exotic like to go a little more outside
little more outside let’s visit some
of the satellites of the planets that
they are outside our house that are in
the distance does not exist a single
that’s the closed side has a
surface is covered in a 99 by
a hundred for the ice and you will see that pointed
it’s like torn is marked
nobody has given you that the seriousness of
saturn breaks and the breaking of red
friction generates heat
that heat could melt the
water could have life but it does not
we need to go to the detail because if
well the plumes that the bottom
that’s steam that ‘s going out to
the surface are literally geysers
of water steam is coming out
It also has organic matter
just below the surface there is a
large ocean of liquid water
we are outside the area of
habitability
this appointment has a very dense atmosphere
1.5 times that of the earth and has a
heap of methane in its atmosphere
we know that methane in the land of
the microorganisms of the prices of the
silver could there be cows there created
microorganisms we already know that that is the
methane comes from a biological origin but
once and for all
geological but we know there are bacteria
that you can eat that goal
so there could be life that I’m
eating and feeding goal is not
europe orbit around jupiter europe
It is about the size of
Our moon has characteristics that a
I’m interested enough to have
atmosphere has water has activity
seismic remembers some planet and that
although a little more exotic I
you remember from the movie of 500 quite
extreme has a very high temperature
its surface because the severity of
Jupiter makes it very active
It has a lot of volcanic activity
literally it is more friendly phosphorus and
Sulfur me reminds me of the
earth millions of years ago
As you can see, there is a lot of stage for
life even outside the area of
habitability
the universe is huge
we live in line you have with
measurable where there are thousands of millions
of galaxies the farm and thousands of
millions of stars and the star
there could be planets some of
them in the habitability zone or
even outside that area of
habitability we find a scenario for
life
He added that we are able to imagine
they invite reflection at the end not
there is so much space so much planet has
life to be much truth
frank drake the director of the institute
seti imagined moment an equation that
they calculated a possibility that there
life but that they are formed
civilizations from that life and
according to your calculations and being quite
pessimist said that they should not have
contacted already about 10 civilizations
every year and only on our site in
our galaxy with two missing goals
a small detail that did not take into account
how much time of a civilization
if you have it in mind for ten years what
that it brought about 80 miles
but loves something happens at the rate
we are going to give you our planet
that we have here more than a million
years
probably if someone comes here
within 345 million years it reaches
the conclusion that life is like a
virus that kills planets and dislocation
habitable and in the end we find life
what happens that means we find
life and departure very similar to ours
which implies we are looking for the same
point but in a different area of the
point we have the same origin and health
very different from us than the universe
is designed so that there is life we are
something exotic within the exotic that is
ordinary matter really very
little we are something quite common in the
universe we do not know and then the other
ask much less world much more
worldly and it’s worth looking for that life
it’s worth looking to invest and spend
a lot of money on those things that never
let’s get to see if it’s worth it
it’s worth it because the important thing is not
it is the goal what is important is the way it is
the path we started millions of years ago
years
That road asks what we do not start
to do thousands of years ago
the important thing is not the goal what
important is the path and all the
questions that we are answering the
way to looking for ourselves
to look for the definition of life hours
