Transcription

  • For thousands of years mankind has questioned the existence of extraterrestrial life in our universe
  • Sooner or later. We're going to see some kind of signs of extraterrestrial life. We need to prepare
  • The chances that aliens exist in some form is highly probable
  • I think it's entirely likely that there's intelligent life somewhere in the universe
  • Today astronomers are already sending messages into space
  • But what if these messages are perceived as threats and aliens believe humans aren't the enemy?
  • If they arrived as conquerors it could be the end of planet Earth as we know it is an invasion
  • Is an invasion inevitable?
  • It would be like Godzilla meeting Bambi
  • Think is almost a hundred percent chance that there are alien forms of life in the universe other than our own
  • If extraterrestrials exist they would come from the far edges of the universe
  • They're fast spacecrafts may already be enroute to our world and there is no way to know when they will arrive
  • Many think that this scenario is possible including researcher Nick Pope who has worked with the British Ministry of Defence
  • to investigate UFO sightings
  • There's no reason why intelligent extraterrestrials couldn't already have started their journey it could be a
  • Year's time it could be a month. It could be a week. They could arrive later today
  • There's no way to determine whether they would come in peace or what their intentions would be
  • Extraterrestrial contact with our planet would change life as we know it
  • Nothing would ever be the same
  • Did you go ah ah so please if the arrival of extraterrestrials could mean extinction for the human race
  • It's impossible to know exactly what would happen but scientist Ben Bohr thinks it comes down to two basic principles
  • Came here, they would be coming because they were curious or because they were unfriendly
  • Our earth is just a mere speck in a massive universe
  • Statistically scientists believe that this may mean that there could be millions of other civilizations like ours out there
  • The Earth orbits the Sun just like seven other planets
  • But our son is not unique
  • It is only one of more than 100 other billion bright stars in our galaxy
  • the Milky Way
  • And even the Milky Way is just one of a trillion more galaxies
  • The universe is a very big place, and if you're talking
  • something on the order of a trillion
  • galaxies
  • each with half a trillion stars
  • It seems like a fairly silly notion to imagine that we're alone in the cosmos
  • Some scientists believe there's only a matter of time before aliens finally reach earth
  • They might be closer than ever before
  • If there is life intelligent life other civilizations in our small part of the galaxy we will find them in
  • In just half a dozen years or so
  • Does life exist in space the answer might lie within Earth's closest neighbor the planet Mars
  • Located over 34 million miles from Earth researchers speculate that Mars is a planet that could support
  • extraterrestrial life in this infinite universe the chances are that the same chemical
  • Processes that gave rise to life will have arisen many many times
  • Elsewhere one place that we might find life is within our own solar system
  • There are suggestions for example that there's microbial life on Mars
  • In 2003 ISA sent the Mars Express probe to the Red Planet
  • Its mission find water the basic substance of life on Earth
  • The images from the Mars camera showed something remarkable deep valleys that cut through the Mars Rock at one point in time
  • Water must have blowed here
  • and in some Mars craters scientists abound frozen water
  • There are even entire glaciers capping the poles of Mars, but that's not all
  • We see images of riverbeds even the image of an ocean so we do know that Mars was once
  • Tropical it was once lush
  • Scientists have been able to retrace the entire history of Mars
  • Four billion years ago a gigantic sea covered 1/3 of the planet this water would have been enough to support
  • microorganisms except suddenly the climate changed
  • For some reason was lost its atmosphere and cooled down and water
  • evaporated or became frozen within the surface soil
  • It may have had life in the past
  • But if just a small amount of liquid water is still present there is still hope for life on Mars
  • a
  • Recent promising sign strange grooves on the slopes of Mars
  • These features can occur when water liquefies in the soil and rock slides back over it
  • Hiding under the barren surface of this planet there might still be liquid water water that could mean life
  • Except on Mars temperatures can drop as low as minus
  • 121 degrees Fahrenheit with no atmospheric protection
  • Dangerous cosmic rays can directly strike the planet's surface is it even possible for life to survive in these conditions
  • To discover
  • Extraterrestrial life to find out that we're not alone in the cosmos. It would be one of the biggest if not the single biggest
  • discovery of all time
  • Extraterrestrial arrival would be a sudden and shocking event
  • No one would be ready our
  • Vulnerable planet could be attacked by hostile invaders
  • If there was an alien spacecraft
  • coming into our solar system
  • We may only have a few days or weeks warning. They are very hard to see
  • To answer the age-old question of existence of life on Mars
  • Scientists take a deeper look at a continent on Earth that can mimic Mars. Icy climate
  • Antarctica
  • Researchers from the German Aerospace Center are looking for extremely feel like organisms microorganisms that can handle the harshest cold
  • They find
  • cyanobacteria micro fungi and lichens
  • Tiny creatures that can still survive at temperatures as low as negative 58 degrees
  • It's team Afyon organism and Saigonese extremophile ik or ghen isms clearly show us that life can exist in the most unbelievable places
  • We find life in the most extreme locations on our planet, so why shouldn't organisms also exist on Mars
  • Which is also an ice cold desert?
  • At his lab in Berlin
  • jean-pierre devera needs to test whether these organisms from Antarctica can cope with even more extreme conditions
  • He has designed a special Mars simulation chamber to put the mosses and bacteria to the test
  • This is our Mars chamber. We've made it as close as possible to the condition of Mars these temperatures
  • Go extremely low negative 58 to negative 103 degrees Fahrenheit
  • To match the paper-thin atmosphere on Mars the pressure is dropped to 6 millibars air on earth contains less than
  • 1% carbon dioxide the air in this chamber is almost
  • 96 percent carbon dioxide under these conditions most earthly creatures would immediately
  • Perish but the extremal philic organisms from antarctica survived
  • So far what I've discovered in the Mars chamber has been very surprising
  • even under the Mars conditions the fungi could form proteins and
  • Bacteria still produced methane these algae and lichen could still be able to carry out
  • Photosynthesis even under Mars conditions for this reason we want to take the next step we need to do these same tests in space
  • To assist with this study the International Space Station is called into action for this unique experiment with a risky setup outside
  • The astronauts assemble an experimental lab on the external surface of the space station several hundred samples
  • Including the bacteria fungi and mosses will be exposed to cosmic radiation orbiting the earth for over a year
  • If these organisms can survive in space they may also have managed to survive on Mars
  • Leave mouth-to-mouth control life can exist on Mars based on the experiments. We've done
  • It's clear that today's Mars is a viable planet I believe we need to seriously look for life on Mars
  • Proving simple life exists on Mars would tremendously fuel the greater discussion about intelligent life
  • Ours will be the generation that makes this
  • literally
  • Game-changing discovery that alters everything we know about ourselves and our place in the cosmos
  • But others in the cosmos may be trying to find our world
  • Chuckles catfish was ultra fun
  • There is no way to anticipate where they would land their arrival would shock humans
  • Muskan assistant
  • They friendly or not who knows I would hope they're friendly and that first contact would be in a friendly fashion
  • Humans need to find proof of extraterrestrial existence before they make contact
  • March 14th 2016
  • At the Russian Space Station in Baikonur, they are launching another new project to find out even more about Mars
  • ExoMars is a joint project of the European Space Agency ISA and the Russian space agency
  • Roscosmos
  • The mission is monitored via Isis control center in Darmstadt flight director Michelle doonie makes sure that the probe stays on course
  • You know that ExoMars mission is to find traces of life on Mars
  • That could be life that used to exist or maybe even still exist today
  • Since on earth
  • Methane is mostly produced by living things the trace gas orbiter is designed to detect methane and then find the source of the gas
  • well
  • a methane on Mars might be generated by volcanoes
  • We believe that those volcanoes are now extinct so it could be produced by minerals, or it could be created by living organisms
  • In the next phase of the mission a Rover will land on Mars
  • Since cosmic radiation makes the surface itself to hostile for life-forms
  • The rover will search for life in the ground protected from lethal radiation under the surface microbes could still be alive
  • This is the first time in history that a Mars rover will drilled two meters deep into the planet
  • If you own the home for fund a prohormone Dunois the deeper we drill the further we can go back in history
  • Increasing the chances that we will find life
  • Look how we dispose
  • The soil samples are examined immediately at the site a special set of instruments onboard the rover
  • analyzes the drill cores for traces of life
  • But even after all this effort there is still a chance that Mars may actually be a dead planet
  • There are still other potentially habitable worlds the two moons orbiting Saturn Titan and Enceladus
  • Could hold wife in the ice that covers them
  • Gas giant Jupiter also has its own ice modes
  • Ganymede and Europa underneath their ice crusts. They may have oceans of liquid salt water, which could be teeming with life
  • Phoenixon I think on our next I'd candidates are still in our solar system
  • We definitely want to look for life on the ice moons
  • One of these moons is very active and we can tell that it is spurting out ocean material. That's exactly what we want to see
  • Something's coming out of the ocean there could be life in that material
  • Future missions could finally reveal if there is life in our solar system
  • Unless highly developed
  • extraterrestrials discover us first scientists believe they could reach our planet a
  • Species that had evolved four million years longer than as the certainiy have the capabilities to send a starship here
  • Could these visitors be dangerous
  • What comes up doesn't get a coach was not popped on demo day
  • This fast
  • That's good, you're very busy
  • What would son should advanced species want from us
  • If aliens decided to conquer our earth would we even stand a chance?
  • If they arrived as conquerors it could be the end of planet Earth as we know it
  • If
  • Extraterrestrials arrive, they will have travelled a great distance from a planet that is very far from our solar system
  • How do we identify where they will come from?
  • One man is getting closer to the answer
  • Swiss astronomer Michelle my or is on his way to an observatory in France
  • It was here in 1995 that he made a breakthrough discovery
  • Luverne UEC we have come here to the observatory of Hawker Falls to measure as many stars as possible in the clear sky
  • In just his first week mayor was able to pinpoint
  • 142 stars and there something very peculiar about one of them star 51 pegasi seemed to be moving a
  • Small strange wobble that made him think that it could have a planet in its orbit
  • Looking at them from Earth most stars appear to have a steady even speed
  • So we have noticed that 51 pegasi we actually changed its speed in a very specific way
  • Mayor has a theory the gravitational pull of this star holds unto a planet
  • But the planet itself is tugging back causing the star to also make the small movement
  • Astronomers call this a change in the radial velocity
  • Which causes a shift in the way the light of the star reaches us back on earth as it moves forward?
  • It is seen as bluish as it moves back. It is perceived as red
  • May or checks these tiny deviations in the light spectrum with his spectrograph
  • Mer is positive
  • 51 pegasi must have a planet
  • This was our proof that there was a planet orbiting the star
  • For the first time ever an
  • Exoplanet has been identified a planet outside our solar system the newly discovered planet is located in the constellation
  • Pegasus 50 light-years away from Earth and it's been given a name 51 pegasi B
  • The idea upon EF this was the first time that we found a star other than our Sun that actually has a planet
  • the discovery of 51 pegasi B is a major milestone in space exploration
  • We now know for certain that exoplanets exist outside our solar system
  • The discovery also is another reason. Why many scientists are convinced?
  • extraterrestrials exist including well known theoretical physicist Michio Kaku I
  • Think is near a hundred percent that we will find intelligent life in the universe
  • To any planets have the potential to support not just simple life forms with the development of whole civilizations
  • Could there be a second earth a planet exists with the same characteristics as our own
  • Three two engine start one zero and liftoff of the Delta 2 rocket with Kepler
  • In 2009 the Kepler telescope was launched into space
  • The telescope's main task fly through space to search for new exoplanets
  • Kepler has spotted over 2,000 exoplanets and the telescope keeps making new discoveries every day
  • The satellite has given us a census of the Milky Way galaxy
  • We know that between fifty to a hundred percent of the stars you see at night have
  • Planets going around them and so the chances that we're the only
  • Planet with intelligent life. I think is very close to zero
  • To this day almost 4000 exoplanets have been discovered
  • Like Corot 7b
  • 490 light-years away this planet likely is primarily made up of hot lava
  • At first glance planet HD one eight nine seven three three B
  • Actually looks like earth, but it has it's blue color for another reason not water
  • But hazardous glass particles in the atmosphere with brutal winds of five thousand miles per hour
  • It may even rain molten glass on this planet
  • 55 Cancri E. May actually possess a diamond core the surface is a scorching
  • 3,600 degrees Fahrenheit and the atmosphere of this exoplanet
  • Contains high amounts of a toxic proceeded life as we know when on earth could not exist here
  • 2.0. I think that's what we'll be looking at
  • Alien invaders may come from a place much like a second earth
  • Then why would they need to come to ours
  • If they truly come to wage war humans would have no hope
  • Military experts believe that facing aliens in combat would be devastating
  • If an alien civilization has the ability to cross interstellar space to reach earth, they undoubtedly have advanced technology
  • If their civilizations are more advanced than our own how can we prepare for contact?
  • Another scientist is also scouring the skies to find a planet where life is possible
  • Hiker hour is an astrophysicist at the German Aerospace Center
  • The big goal we have is to find planets that are similar to our earth habitable ones where we might be able to find life
  • Hiker or knows the key is to find planets with a solid surface and water the two attributes that seem to go hand-in-hand
  • with the existence of intelligent life
  • If I push the earth closer to the Sun it would get hotter
  • Some oceans would evaporate, and then we would have a planet that was not inhabitable
  • And if I push the earth farther away from the Sun
  • It would be so cold that the water would freeze and we would just have an ice planet our planet wouldn't be habitable then either
  • So there's a specific ideal distance from the Sun
  • We call this area the habitable zone
  • This habitable zone is the only place where life can develop but for them to happen the planet also needs an atmosphere
  • Like the thin gas layer
  • Which also surrounds our earth protecting life from the lethal UV radiation emanating from stars including our own Sun?
  • The atmosphere is
  • Also crucial of course because we breathe and we need the oxygen from our atmosphere to live so a planet must also have the right
  • kind of atmosphere
  • She uses a trick to quickly find habitable planets
  • Wherever a planet flies past its star at this precise moment the star darkened slightly
  • Using the strategy researchers like hiker hour now have detected more than 30 planets in the habitable zone
  • That could be full of life
  • One planet looks particularly promising to researchers
  • kepler-452b a planet 1,400 light-years away in the constellation
  • Cygnus, this planet is amazingly similar to earth its star has a similar size and temperature to our Sun
  • For a round trip around the star it takes
  • 385 days
  • Just a little longer than our Earth's orbit and the distance to the star is just right
  • Closer to finding a world very much like our own
  • I think it's only a matter of time now, and I think it could be
  • staggering ly close a
  • New European telescope has the means to finally find this second earth
  • This advanced device is called the European extremely large telescope e-elt
  • For short by 2024 the telescope will be stationed in the Chilean desert. It will be the largest of its kind in the world
  • at the Assembly Hall of the European Southern Observatory
  • Technicians test the parts that will later become the telescope's main mirror
  • So what do we have here is the very first prototype of the primary mirror of the ELT?
  • So we need a very large mirror, which is impossible to build today in a monolithic piece
  • Close to 800 individual hexagonal mirrors will be put together to create the telescope's 40 metre massive mirror
  • Up to now we've been building telescope up to 8 to 10 meters
  • But now we have a technology to build something which is extremely large
  • 40 meter in diameter is as big as the Alliance Arena nearly, and it's enormous
  • The scientists hope that the telescopes power will finally prove that there is life on an exoplanet
  • They want to use the telescope to examine the planet's atmosphere
  • As soon as the planet moves in front of its star using the color
  • Scientists can determine. What kinds of molecules it contains
  • The ultimate proof is to identify some specific
  • Markers some ozone for example some specific elements in the atmosphere of this planet that can only be produced
  • By life by plants by by little creatures in in in the in the ecosystem
  • With the new telescope researchers are aiming to find proof of life within the next 30 years
  • So Stefan our lifetime so in the next decade will be able with ELT to really understand
  • If there is life potential life or not
  • Is it possible that
  • extraterrestrials are already also watching us are they planning a visit and
  • for what purpose
  • Sooner or later we're going to see some kind of signs of extraterrestrial life
  • We need to prepare
  • An
  • Extraterrestrial attack would be the greatest catastrophe in human history
  • So that fabulous custom fucking
  • Its life out there like on earth
  • It probably shares some of those
  • Characteristics at life on earth has is there any way to predict what the invaders will look like some researchers believe that
  • Aliens might be extremely similar to us
  • I think there's a great chance that some
  • Extraterrestrials would look exactly like us so for example eyes are very useful
  • Legs are very useful for mobility those things may be present elsewhere in the universe so I would not rule out
  • some
  • extraterrestrials being indistinguishable from human beings
  • Different environmental conditions
  • Could mean that life from other planets would look drastically different
  • These organisms would need to endure extreme heat or extreme cold
  • If they came from a planet with stronger gravitational forces
  • Extraterrestrials may have adapted and developed massive muscle to fight against gravity's pull
  • Small compact creatures would have the advantage on this type of planet or a planet with less gravity
  • Aliens would need much less muscle to move around their planet could be populated by thin giants
  • All life on Earth is made up of carbon and water, but in another world
  • It's possible that life developed from entirely different chemical elements
  • On Saturn's moon for example
  • There may be no liquid water, but there are still other building blocks. That could be combined to form life
  • so creatures on Titan could use ethane or
  • Methane as a liquid instead of water
  • Then the building block would probably be silicon instead of carbon and those creatures
  • might breathe in hydrogen instead of oxygen so
  • Life could be very a lien on that world
  • There's also the possibility that the visitors will not be actually alive
  • Aliens could potentially send their own intelligent machines into space
  • We actually meet them in person
  • They may already have bioengineering and artificial intelligence
  • So don't be shocked to find that they're part robotic and part biological
  • Many scientists think that it's entirely plausible that aliens have developed advanced spacecraft capable of reaching earth
  • Yes, it's very possible to do interstellar travel
  • it just takes a lot of effort and a lot of money to develop such a spacecraft universe a
  • Journey through the stars is already within reach
  • Russian millionaire Yuri Milner has invested 100 million dollars into the u.s.
  • breakthrough iniciatives project and others are on board including
  • astronaut Frank Drake and even star physicist Stephen Hawking
  • Search for life beyond Earth it is important to us to know if we are alone in the dark
  • The plan is to visit our neighboring star system, Alpha Centauri
  • only 4.2 light-years away from Earth
  • Scientists have discovered that in this system the red dwarf star Proxima Centauri is orbited by an earth-like planet
  • Proxima B sits perfectly in the habitable zone making the planet a prime candidate for harboring extraterrestrial life
  • But it would take an unmanned probe 32,000 years to reach Proxima be
  • Milder and Hawking believe we need a mini probe
  • which will be able to make the journey in only 20 years if
  • The probe weighed only a few grams it could be equipped with a sail
  • Extremely powerful lasers on earth would then be aimed at the sail and in just 10 minutes
  • The probe would be pushed by the lasers and a quarter of the speed of light
  • For the first time in human history
  • We can do more than just gaze at the stars. We can actually reach them
  • traveling at a speed of
  • 45,000 miles per second it would only take the ultra light spaceship 20 gears to reach Alpha Centauri
  • If sentient life is based upon expansion and based upon exploration
  • Then it's entirely likely that other sentient species are also engaging in interstellar exploration
  • Advanced civilizations could have developed entirely different technology some researchers believe that the most progressive
  • Aliens can tamp the energy of entire stars to create wormholes that they then use to travel through space and time
  • We have come from
  • horse-and-cart to stealth fighter and space rock yet in 200 years
  • Now imagine a civilization with a million year head start
  • Which is not difficult to conceive of in a universe 14 billion years old?
  • So let's not rule out the fact that if there are civilizations out there. They may come knocking on our door
  • Invasion by a higher tech civilization
  • Poses a serious threat to the human race in an attack we would barely stand a chance
  • Humans would need to find shelter and safety as soon as possible
  • If this crisis would come to fruition everyone would be caught off guard
  • But I think it's important to consider the possibility of interstellar species approaching the earth that might be hostile and
  • Consider what resources we might have at our disposal
  • To allow us to defend ourselves
  • and
  • Time may be running out
  • Aliens may already be heading towards their target earth
  • But some alien hunters are more optimistic
  • One of the most famous hunters believes that aliens will be peaceful Seth
  • Shostak has devoted fifty years of his life to SETI research the search for extraterrestrial intelligence
  • The American astronomer is convinced that his body of work will pay off
  • There like a trillion so that's a million million planets just in our galaxy
  • It's like you bought a trillion lottery tickets
  • You know a couple of them are gonna be winners, so it just strikes me is inevitable that there is other intelligent life out there
  • Someday we may be able to actually communicate with
  • Extraterrestrial civilizations, but are they already trying to get in touch with us
  • to find out SETI researchers
  • Use radio telescopes like the Allen telescope array in California
  • These telescopes can receive acoustic radio signals from deep within the universe
  • We point them in the direction of nearby stars, which we think might have planets which might have life
  • Which might have intelligent life?
  • And we just look for signals that are coming from those directions
  • Signals at one spot on the radio dial that would tell us hey, you know I don't know what they're saying
  • I don't know what they look like but they've built a radio transmitter and
  • Once upon a time a signal just like this one reached Earth
  • 1977 the Big Ear radio telescope of the Ohio State University as its antennas aimed directly into space
  • using these antennas the telescope could capture every radio wave lying in its orbit and
  • Suddenly it received a strange signal from space
  • Astrophysicist Jerry Amon was working on the big-eared telescope. He could hardly believe it when he analyzed the recorded data
  • In those days all the data were just printed out as numbers on a big printer
  • And he would just go through it and look to see if there was anything interesting that it happened that night before one morning
  • He finds a big signal and he gets so excited about any rights Wow
  • Next to it
  • This wow a no came from the constellation Sagittarius?
  • 200 light-years away from Earth
  • with a 30-fold standard deviation the signal was strong enough to be heard over the background noise of the universe and
  • May have been sent out by another civilization
  • But the WoW signal was never detected again
  • To this day it is unclear if it is a result of something natural or if it was caused by something else
  • If extraterrestrials are sending signals to us. What would happen if they personally paid us a visit
  • People would respond in many many different ways some people would literally I panic in the streets
  • Chaos and violence would strike the cities of earth our world as we know it would collapse
  • Just go
  • Beer shock panic anger it's entirely likely that humans would be terrified
  • At the SETI Institute in California Seth Shostak and his colleagues are still looking for recent signals
  • the astronomers evaluate data from radio telescopes all over the world
  • To date they have not found any evidence proving that
  • extraterrestrials exist therefore many scientists criticize SETI search methods
  • We look for radio signals from
  • Intelligent planets, but that's looking at the wrong frequency
  • Why should they use old fashioned radio to communicate?
  • The alien hunters have not given up to finally get in touch with
  • extraterrestrials some SETI researchers
  • Think that we should play a more active role in
  • Communication instead of listening to distant signals our own messages should be sent into space
  • if you send to some nearby stars
  • So they're not terribly far away 10 light years 20 light years then maybe you get a response while you're still life and it can
  • Enjoy a response
  • It would not be the first time that astronomers have sent a message to aliens
  • In
  • 1977 the Voyager 1 probe made its way into space
  • Since then. It is reliably sent back data in images from our solar system
  • Precious cargo is stored onboard
  • the Golden Record a
  • copper disc that holds music images in sounds from the earth
  • Greetings recorded in 55 different languages a way to kindly introduce ourselves to foreign civilizations
  • Konichiwa ohgenkee deskah
  • hola saludos
  • in
  • 2012 Voyager 1 became the first probe to leave our solar system
  • It is flown further into space than any man-made object ever before
  • This cosmic message in a bottle will travel even deeper into interstellar space
  • By 2025 the probe will run out of its energy supply and continue into the cosmos
  • uncontrolled
  • With the aliens have refined these spacecraft
  • I don't think so they're about the size of a Volkswagen Beetle
  • Right and they're dark and and their transmitters won't be working then so how you ever gonna find these guys
  • It's like you know looking for a don't know a little bit of flotsam on the Pacific Ocean you're probably never gonna find it
  • Acoustic signals are already being sent out into space
  • The most famous signal was the Arecibo message in
  • 1974 the message created by astronomer Frank Drake used binary code to provide information about human biology
  • The population on earth and tell the recipient exactly where the signal originated so far
  • We haven't received a reply from aliens
  • Seth Shostak thinks we need to be thinking bigger in fact
  • He wants to offer big data to the aliens the more information. They receive the better
  • They will understand us. I would send the Internet actually we just send everything on the Internet
  • I mean if you walk down to the beach
  • And you find a message in a bottle and it's one sentence you may never figure out what that message was about
  • But if it was you know a thousand books
  • Well you might you might a lot more
  • But others think that these well-meaning messages would make us in calculon
  • enemy aliens might leverage these communication efforts into a full-scale attack I
  • Think it's a rather silly idea to send out
  • powerful beamed messages
  • Indicating our presence who knows what's out there in our galaxy. It's like being a
  • four-year-old in the middle of a dark forest
  • Does she
  • explore and learn
  • The situation or does she go running screaming through the forest saying
  • monsters hello
  • Everybody I'm here
  • Critics say that stopping these messages is the only way to prevent a human catastrophe
  • Before proceeding there needs to be a greater scientific discourse
  • About what these messages should contain and who is allowed to send them I?
  • Think we should hold discussions
  • serious
  • scientific
  • Investigations and discussions of the pros and cons before we be messages into space
  • Early projects like Yuri Milner's are already underway for the best message. That could be sent to
  • extraterrestrials a
  • Reward of 1 million dollars is up for grabs
  • Though we previously also warned against sending messages Stephen Hawking now supports the endeavor
  • It's time to open our eyes our ears and our minds to the cosmos
  • if
  • extraterrestrials received our signals long ago
  • Now it's too late for us to hide
  • Any society that could do that any society that could come here and threaten you
  • They've got bigger antennas than we do they can already pick up our television our airport radars all sorts of stuff
  • So we're already telling them. We're here
  • Pandora's Box might already be open
  • At this very moment aliens could be enroute to earth
  • And Stonebridge muffled he would you own advocate and I'm not five time thus militares an alarm, but I trust in Verizon
  • Does not met
  • And honest
  • Isn't fast as you have
  • If there are more intelligent more powerful and therefore more dangerous civilizations out there
  • We should be very careful about
  • Contacting them
  • These fears are not unfounded in the history of mankind when a new country or continent is discovered

  • Say this could be our new home would universal war with
  • extraterrestrial life be plausible solely for our resources
  • But so many planets out there orbiting stars that will have water and carbon and all the elements that are on earth
  • There's no reason to come to a planet filled with life
  • Our planet is home to 7 billion people
  • to aliens the most interesting resources on Earth might actually be its inhabitants
  • If they are warlike it would be like

  • the first objective would actually just be survival the second priority would be the capture of enemy technology and
  • Reverse-engineer them it may be possible for us to produce them in significant quantities even
  • If aliens haven't planned to deadly invasion it could still turn into war if we get in their way
  • And even if the aliens don't wanna conquer us
  • Even if the aliens don't want to eat us eat at the aliens don't want to plunder our natural resources
  • We might get in the way because maybe they have different intentions toward us
  • Humans would have no way to escape
  • If an enemy arrives that has such a massive disparity in their technological capabilities that you have no means of
  • Potentially fighting back then perhaps your best opportunity to survives to accept the changing nature of your civilization
  • They came here with friendship
  • As explorers that's great we would hold out the hand of friendship ourselves if they came as conquerors
