they travel the surface of some planet
they fly in its waters and its skies sail
but it's not a safari in the
planet earth but of an expedition
of astronomical proportions when the
humans we discover that we are not alone
how will our brothers and sisters be
cosmic to answer this question
to several astronomers and astrologers
recognized prestige have applied the
principles of evolution and physics
to five types of worlds that
we probably discover in the cosmos
these are the creatures that could
inhabit the
Music?
prepare for a safari
intergalactic and look at the eyes to
these extraterrestrial creatures
the universe extraterrestrial creatures the
Variables
Music?
an intergalactic sanctuary of thousands of
millions of galaxies and billions of
Stars
it could be no more than an aggregate
lifeless territory of outbursts of
gamma rays stars in combustion and
black holes
or there is life beyond the earth in
this cosmic paradise will seek us
extraterrestrial creatures pondering
the big question we are alone
scientists are still looking for
first signs of life beyond
our planet but many are
convinced that they are out there
waiting for us to find them
but what will be its appearance
with an interesting combination of
Earth science logic and theory
of evolution
graphic artists can give life to
some of these creatures
extraterrestrials and to face us
Face these creations
aliens we embark on a
imaginary safari through the
unexplored corners of the universe like
would a tourist in a zoo
intergalactic
Music?
our first stop will be the planet
hypothetical with him
Music?
but he is a strange planet
first of all it does not orbit around
a star like our sun but
around a little red dwarf one
movie star and they can have a
size five or six times smaller than the
of our sun
therefore the living area will be
much closer to your star
Music?
this habitable zone is a piece
essential of the puzzle that supposes
understand the evolution of life in
any other planet
the habitable zone of a solar system
that distance from the star where the
water can exist in liquid form in
the surface
this requires enough energy
thermal of the star so that there
liquid water and stay well the water
liquid is one of the elements
basic for life to emerge
Music?
but January in the habitable zone is
so close to the bright sphere of
gases in combustion that the severity of
its star makes the orbit of heron
the asynchronous pse the same thing that happens
between the earth and the moon from which
we only see one face of its surface in
every moment
this would mean that in a half of
hison he would be constantly daytime
and the other would be immersed in the
darkness in between opened a zone of
about 300 kilometers wide between
north pole and the south pole where
I would live in a constant twilight
mezzo that makes us wonder where
life would be found on that planet
the truth is that there would be life in all
parts but on the dark side they would be
adapted ways of life to live in
the darkness and on the illuminated side
we would find locations adapted for
live only on the site and in this
twilight zone we would find
creatures adapted to live in both
areas that can wander through both
sides of this world would control
really your own destiny with respect
where to go where to marry
in the coat photosynthetic organism
probably lichen in an environment
marine a red alga or a bacterium
gifted absorb infrared light get
energy from it and create food in
earth would be something similar to unican
Because it's cold
some musicians adapted to that environment
and there could be organisms that
feed them is lichen
represents January on the basis of a
very long food chain all
plays a vital role for the
survival of plant life up
the largest and most complex creatures
an example of a creature from the USA where
uses this lichen as a source of
food is the insect known as ey

the iphones are small and
strange creatures of the earth
we call metamorphosis the curious
ability of a creature to change
one way or another it always happens with
the butterflies the caterpillars that we see in
our gardens form a chrysalis
and months later they emerge as a butterfly
changhua paragraph to iphones
they also do it but in a very
strange they are like eels with suitcases to
each side of corpses sainz in a
particular moment they approach some
vegetable form of life and closes on
themselves forming a shell when
that shell opens up now something comes up that
we have never seen before
absorbs hydrogen from water
separating it from the oxygen inflate a
small bubble and they go away from the
water
the breeze makes them ascend to a
great height
scatters them across the planet towards
twilight zone and it falls as if they were
paratroopers
when the six men hit the ground
immediately build a burrow
where they usually live
but at the same time that there are
they dig to the ground in search of food
they are also hunted from above by
one of the next links in the
food chain
the nickname pin is one of the most
interesting about this world are some
small and strange creatures whose
eyes encompass all their surroundings so
can perceive any movement
behind them the twilight zone of heron
he would be a dark and cold place
due to the low light it receives from its
star and the players and also their
6 portions
they will have developed big eyes like
owls and other nocturnal creatures
here on earth but most of
the creatures of Leonel have developed
another interesting adaptation with the
orbit around a class star
m
most of the light emitted by the
class stars m is infrared a
light that is really heat what
we feel when we open the oven
Music?
that's what these creatures would see on
heat that the bodies give off in the
the world that surrounds it
they wanted something very different from what
we see ourselves perceiving signs of
heat on the dark side of the planet
gives one great advantage one of the
older links in the chain
US food on it

by their sense their movements and the
way they act together they look like
the jackals of the plains of africa
they move emanated they are hunters
predators creatures be and
unpleasant that surround the nicknames
to hunt them and feed on them
they have a strange ability
besides seeing the things he sought
with normal normal eyes
on that planet he has a second pair of
smaller eyes that allow them
perceive signs of heat from the
creatures that live in the dark zone
in which it is always tonight
these are just some of the creatures
that could live on a planet like
it was him but at least for now they are not
more than products of our
imagination
Music?
we scientists can imagine the
life in other places but we do have
examples we have a reference point
and it is the planet earth
therefore study life in the
Earth provides us with information
very valuable that we can use to
look for life in other places we can
study a variety of
ecosystems and observe the challenges that
pose see what those
challenges of the living beings that live
in them and how we can apply those
early extraterrestrial life
to understand how they can be applied
these principles we must continue
our imaginary safari
intergalactic we leave the surface of
eronel and we travel a distance of 300
22 light years through the cosmos to a
new solar system and the planet
hypothetical ag 143
Music?
AG 143 is bigger than Earth
much larger than the earth and in a
beautiful ring system to your
around but the most important thing is that
it is a gigantic dry desert
with a gravitational field three times
more powerful than we feel here
on earth a human being who passed
approximately 80 kilos on earth
would weigh about 240 kilos on the
beam surface that 143 certainly its
life forms are well adapted to
it but as of life aguilar del
astrophysics center of the university
from harvard
I think the best way to foresee
adaptations of complex ways of life
extraterrestrial is to observe the variety
of creatures that have evolved to
avoid the various ecosystems of
our own world
Music?
we meet at the zoo
North Carolina because of all the
zoos of the country this one is very special
tie is big and wide and its environments
simulate the different environments that
we find on our planet is a
wonderful example of the variety of
life forms of our planet
Music?
Aguilar believes that among the variety of
earthly life forms the creatures
that support a structure
extremely heavy on the model
perfect to understand evolution
in attachment 143 when we talk about an animal
adapted to a heavy environment a world
more serious
this is what we have to study we can
see some legs that can hold a
huge body of course they would have to
be further down closer to the ground
but it is a perfect example of what
we would see they would be lower creatures and
compact will be as heavy as this one and
adapted to a planet with a serious
much more intense
Music?
although life forms of aje 143
they have certain characteristics
comparable to those of creatures of the
earth does not look like anything we can
find on our planet
Music?
and if one day a space probe
profoundly detected life outside of
our solar system
what an extraterrestrial would look like
to better understand these creatures of
other worlds and how could there be
evolved
Scientists believe that we must first
understand some basic concepts
about the physical environment where it could
originate life
when observing planets that orbit
distant stars
the scientists start from two
factors the first one is the distance that
separates it
that determines how much energy
will determine whether or not there will be liquid water
second its mass the size of the
planet that determines its severity and what
type of organisms could harbor
when we think about biology
evolutionary we tend to imagine a
nature of red teeth and
claws Darwinian competition between
organisms species and others but
we forget that it is the physical environment what
that really shape life
the intensity of gravity the
temperature pressure composition
of the atmosphere if there is
atmosphere and all that
the laws of physics do not vary
when we travel through space
therefore understand how
the creatures on earth evolved
has allowed scientists to imagine
what forms of life could appear in
other worlds like the hypothetical planet
make that 143 ag 143 orbit around
a bright star of class f
only 10% of the surface of this
world is covered by water and the
scarce liquid h2o that falls in the form of
rain accumulates in bags under the
sand the environment cast 143 is hot
arid and the sun shines very intensely
it is a class star f
It is brighter than our sun and its
ultraviolet emissions would be very
intense therefore the organisms
they will have to be protected from some
way either by the atmosphere or by
your own means
these protections can adopt the
shell shape or other type of
thick covers that absorb the
intense ultraviolet radiation but the
creatures of aje 143 would develop
also other physical characteristics
exclusive of this world is really
interesting to imagine how it could be
life on a planet with more serious
with respect to microbes could not
make a big difference
the differences could start at
notice for example in the ways of
lives that live on the ground and have
to stand up
damn gravity can not even get up
Music?
however another consequence of a
severe severity could result in a
unusual fan of creatures in the
anje surface 143
or more exactly a little bit above
the surface the atmosphere of the earth
it consists of 79% nitrogen a 20
percent oxygen and 1 percent
of other gases that stays in its
place because of the attraction
gravity of the earth but in a
planet as aje 143 greater gravity
would cause a much more atmosphere
Perfect dense to lift the flight
it could also assume a proportion
much greater oxygen
we believe that a couple of hundred ago
millions of years the earth lived a
period in which the concentration of
oxygen was greater for a while and
what the fossils show us are
giant insects to the huge
giant flying organisms
if we think about it, they had more
oxygen for your metabolism more
energy to do things would be like
use an oxygen bottle and notice
that you have more energy
that's how those organisms would have felt
with a denser atmosphere and a
higher oxygen concentration
iag 143 titles would be
full of great flying creatures
that could stay in flight all the
time you need to be an example
it could be the sargal
this creature lived most of
your life plowing through the atmosphere in search
of the few water bags that
they dot the planet when they go out
find one of these bags not only
would descend to drink but also
to hunt any creature that
I could have reached this oasis
a creature like the mobile amx to
first sight we could confuse a
mobile and with a starfish has
some arms bones with which
they move through the desert
the curious thing about these arms is that
They have long tentacles that
probes the sand in search of valuable
water bags that could hide and
more curious even if it is strange
creature finds a large bag of
water begins to collect the water as if
I was taking it out of a uaw bag and
increases in size more and more
storing the water as a
hair
adapt to locate and store the
Water is crucial for survival
be in the middle of a desert to hundreds
of kilometers of any kind of
Liquid
would be a death sentence for almost
any creature on earth
the same thing would happen to living beings
on the hypothetical planet AG 143
that's why the cops live mainly
near water tanks to not
get away too much from this valuable
resource
the cops are the creatures most
strange of aje 143 are low and robust
a mouth resting on three legs on a
platform that has scales under it
they move on the sand sliding
the viper of the desert and the strange
ability to chemically detect if
your company is near or not in the kazan
around the banks of streams and
small lakes and if they discover their
prey they decide suddenly they stay
motionless and camouflage resulting almost
invisible wait for some
hapless creature comes out slowly
of the water and suddenly I have found
your dinner
the way the cops move
slipping through the surface
like a snake on the grass is
another evolutionary characteristic caused
by the intense gravity of the planet
slide on scales instead of
lifting the legs would be a lot
easier to any creature
also offers a stealth advantage
about their prey
you may have never heard I denied a
Felix but the food chain
continues on ax 143 and nothing is to
except in these pools lurks a
Silent but lethal creature chosen
students during our examination of the
food chain in aje 143 we have
seen the challenges that must overcome
the creatures of a world with a shortage of
water on its surface and a seriousness
greater than that of the earth
but what would happen if the conditions
of the planet were the opposite
would happen on a planet with a
amount of water suitable for
development of life but also with
a much smaller gravitational force
the answer could be just over
our heads in the heavens of the
land
in our intergalactic safari we have
seen as reputable astrobiologists
they use current terrestrial science
to raise hypotheses about the
size the shape and behavior of
the creatures of an imaginary world with
a severity much greater than that of the
land
Music?
but what would happen if the severity
was much weaker to find out
we will leave behind the intense gravity
of ax 143 to direct us to another
planet located 89 light years away from
remotely
gpc in 925 gpc 925 is smaller than
the earth 50 percent
approximately.
although it has many similarities with
her but being smaller her
Sever
It is also less
Music?
the star around which it orbits is
colder than our sun and because of
that's a combination of icy areas
and photosynthetic green plants that
appear between some bodies of water are
it would look a lot like the northern part of
our planet to the northern taiga of
Canada and Greenland
Music?
the environment of the gps 925 would be very
homogenous in this world not
we would find deserts and very few
mountains would be a cooler world and
better preserved than our own
planet but equally beautiful this
world would generate more life forms
large and elegant
I look two meters imagine what would be
my height in a world with half or a
third of severity or what aspect
would have a redwood in a world with
less serious
these gravitational effects would give
place to different characteristics in
the beings that inhabit the surface
also in a world like boss in 925
great part of the beings that inhabit 100
on their surface they would not do it in the
own surface
Music?
we meet in him daily in these
trees inhabit the descendants of
The dinosaurs
this is what the dinosaurs left
when they disappeared these birds have
evolved to fly your bones
holes can join and close the pens
these birds were destined to govern
the heavens but with a gravity less
intense we would see that they have reached
govern the planet because of the scarce
gravity in it would be very easy to fly
on the ground numerous agencies have
flown in different ways
the bats extend the membranes
who possess the fingers to create the
flying squirrels spread their fur
so I can plan
but not all dgpc creatures 925 are
similar to others on earth what
flirting are the creatures of the air more
strange that we can imagine
imagine similar floating sacks
to lungs swollen with
Very long tentacles that
dragged across the field and advanced
floating on the landscape and its heat
interior would raise the temperature of the
air inflating your sacks would look like
It's jellyfish that float in the air and
just like jellyfish and karim ziani
they would catch anything that ran
on the floor before them see the
needs up and down the wind
as a group of psychedelic jellyfish
surpasses our imagination and without
But here they are very common here
even life on the surface
would go beyond the limits of science
as we know it
to get an idea of this world
think about the tax laws seem long
heaps that you leave six eight or ten
meters in the air a large number of
them with a bulb at its end this
way subdued by the wind but most
surprising is that they are not plants are
animals with roots that stand up and
slowly travel the surface of the
planet and they return to fix themselves to the ground
while they are rocking in the wind they await the
step of any creatures
when one appears its top
it shoots like a frisbee and it
dig into the side of the creature
the supa is in its shell in its
hair and gets caught immediately
when they move and reach an area
new they alight and begin to cross over
new is simply part of their
seeds through these little discs
that they throw through the air
every time they notice that something is coming in
this planet and plants and herbs that
they do similar things but there is nothing
of that size and size sacha next
and the idea of plants that look
animals and animals that look like plants
make this world a very place
weird and that happens
creatures like the kings taxi the leagues
they would enjoy an adequate amount
of water in chief in 925
but what would happen in a world where
there would be even more water
Music?
much more specifically on a planet without
solid ground some an aquatic world
Music?
Music?
since we embarked on our
intergalactic safari
we have seen the amazing life cycle
of the ceipoms or january in the strange
aspect of the polis sell 143 kilos
float in boss 925 all the
hypothetical life forms of these
imaginary worlds has been created by
scientists based on our
knowledge about the development of
life on earth
Music?
but how would these originate
creatures in these strange and distant
planets the requirements that we consider
necessary to originate life is based on
the life that we know chemistry that
as we believe leads to the origin and
evolution of life is the chemistry of
carbon in aqueous solutions or
aquatic so water is needed
liquid carbon and nitrogen nobody
you need some kind of energy because
life even microbes need
food some kind of metabolism
that's why a source of
energy sunlight works
pretty good but it's not the only one
even on earth
for hundreds of years the
scientists believed that sunlight
it was the only source of energy for the
life
Music?
but in the last new decades
discoveries showed that they were
wrong
Music?
it was once believed that servants
temperatures that the water reaches
around hydrothermal vents
from the bottom of the sea were incompatible with
of life.
but scientists have discovered
recently that the areas around
these fumaroles are perfectly
adequate to house a flourishing
underwater community instead of the sun
these creatures receive their energy from
heat the gases and minerals that
expel these sources
These mates life forms are known
as extremophiles the existence of
extremophiles expands the limits of what
what we think and what we know what
can organisms do
in other words if we look at the
different environments that we find
here in the earth
there are extremely cold and
extremely hot to acids and
alkaline almost anything that
we can imagine and we find life in
almost all of them the fact that there is
life on earth is largely due
to our position in the solar system
scientists used to believe that
only life could arise on a planet
within the habitability zone there
too close to the sun because the water to
boil and gymnastics far away because it
would freeze just what is necessary to
dispose of a liquid ocean in the
that could form be of today we know
that that conception is wrong
today we believe that even in the moons
frosts of planets like jupiter is
possible that life comes
europe is a moon of jupiter that is
ice cover but under the ice
there seems to be a gigantic ocean
maybe stable for billions
of years that contains liquid water
that caused a stir among the
physical as there may be liquid water
so far from the sun
hence the concept of flexion of
dizzy mary's bending of europe
is caused by the immense size
immense gravitational force of jupiter
that cause the movement of ice in
its moon which generates heat
when the lower layers and isolated
they get warm enough
the ice melts creating oceans
if we add organic compounds
that is believed to exist in Europe
we get a slightly altered recipe
but very feasible to create life
this brings us to our next
stop in our intergalactic safari
we leave behind the silos of ax 143 and
its creatures to travel 72 light years
even a hypothetical gas giant
called had a plan urgently e is
surrounded by eight moons usually not
we would lose time congeniar g
it's a gas giant and we do not think that
there can be life in these worlds the
world that we are interested in is your moon have
Hervás is approximately twice as
big that mercury is a very world
similar to europe the moon that orbits in
around jupiter a match
imagine a planet is covered in 12
euros and a large ice area
amount of ice that covers all this
planet lacks soil on which
walking from the oceans could be
full of life
given the constant attraction of her
the G
most likely they have boiled
I have an intense geothermal activity
that could be a source of energy
crucial to the origin of life
Music?
near the surface of anievas a
small amount of light could
filtrate to the water through the
thinner ice layers some
creatures could have developed
eyes
this could mean an advantage but
It also makes them vulnerable to certain
defense techniques
here is a cunning expert in evasions
He loves voice for us light is only
light but think of him he loves voice a
small creature almost gelatinous that
nothing innocent by the water if it approaches
something that considers a threat
throws a bright flash of light
bright around him with that
deny any creature that comes near
and slips away that looks a lot like the
cloud of ink from a squid an octopus
soon it is surrounded by bright lights that
they look like fireworks you hear
uses light as a mechanism of
external protection genes
but the creatures that live in the
oceans to much greater depth
would develop other methods of
survival is the case of the fwa lina
the dens look like a cross between a
Very rare spider and a very crab
strange but they have a capacity
peculiar do not perceive your world through
of the eyes but not through the
ears most perceive it through a
electric field that generate around
of their bodies can extend this
field to perceive everything that moves
around you perceive what you
surrounds how this field affects
Electric
the most interesting thing is that once you
they have looked at something they consider a
prey wait until each
more time
and suddenly flash
Music?
they give off a big electric shock
that stuns his prey throws a
tentacle and the trapa to collect the
house using electricity after
see the enormous challenges that these
creatures would have to overcome in a
aquatic world
we still have one last factor left
Explore.
when the inhabitants of the earth
discover life in the cosmos or some
way of life have decided to show themselves by
end to the human race could not be treated
of a biological entity
instead of blood and carbon meat
it could be made of steel and silicon
Music?
a machine
Music?
as we get closer to our
last stop the hypothetical planet
galileo we discovered three great
craters on its surface
the collision of an asteroid with a
planet capable of harboring life would be
catastrophic but galileo is different
when we get closer we see tiny
mechanical creatures hovering over their
surface although so far our
trip has studied an imaginary corner
of the universe full of creatures
biological of all shapes and sizes
some scientists believe that a world
extraterrestrial could be a land of
synthetic machines such as gaia leo
the doctor seth shostak of the institute
seti whose mission is to search
extraterrestrial intelligences
I think when we discover life more
beyond the earth our relative
cosmic could be steel and silicon
instead of flesh and bone
the extraterrestrials that have reached
the ability to build a radio
transmitter and emit so we can
listen to those probably have given
also the next step and that step
it could be the development of machines
thinking
scientists say that for
better understand the origin of a planet
full of this type of machines not
we have more to study evolution
of intelligence here on earth
specifically artificial intelligence
we could say that intelligence
artificial is the science that allows
make babies from scratch instead
to use the traditional system
science and engineering try
conform a mind through the
understanding of its operation
we have not yet achieved
we have not built thinking machines
but the people who work in this
field
they think it's likely to happen inside
of twenty fifty or a hundred years to
means it is possible that within hundreds
or maybe thousands of years
we are combining them with our
machines we must realize that
in the next centuries the machines
they could become smarter
that we always exist the danger
that our creations do not
lock in zoos throw us away
peanuts and make us dance like
we have made bears dance
in both
but instead of merging with the
machines humans we could
become machines someday and
once the processors surpass the
human brain capabilities
the most sophisticated programs could
grant these beings an insurmountable
Advantage over us
if there were artificial intelligences
directing and thinking brains a
million times faster than the
human brain
theoretically they could perform the
thoughts of 10,000 years in three
days and a half to reach similar
achievement would require huge amounts of
Energy (%

then other gadgets called

an almost unlimited amount of energy

think that the earth only uses one
small fraction of the energy of the

if the sun was headquarters this size
the earth would be the size of a

percentage of the sun's energy for
Harnessing your energy could
build a hypothetical structure
called tyson sphere around the
sun or any other close one
Tyson's sphere is a gigantic wait
that is built around a star
to absorb all your energy
this way you can absorb all the
that it emits without suffering damages during the
process when the energy has been
fully seized the fishermen are
fishermen could dismantle the sphere
and push towards the next battery

if the scientists are right
this rebellion of the machines could
even happen on one more planet
close to ours

scientific advances that broadens the
limits of what we know not only from
ourselves but also of life
in the universa out there there is a world
new
or maybe many waiting for us
