3:30 am
you know i'm not so sure about that whether there is a resemblance i'll let you decide that's how about the news that this christmas day i'm back with the top of a. small
3:31 am
room good i'm. stupid to eat. into. the so the for so. los angeles the city of luxury and fame but also an alarming number of people living in the streets. the simple fact in l.a. is there's just not enough shelter even if people on the streets right now decided to come in there's nowhere to come in it's business. this man's blown his own
3:32 am
response of the problem and constructed dozens of tiny homes for people in need of shelter when you have nothing and nowhere to go. you know having something like this may as well be a castle but do the authorities accept such true lucian. the house on a city parking space is not a solution. to someone that wanted to ring the site otherwise it will be a free for all there a better alternative to end the homelessness crisis. but whole existence to do something to. put themselves on the line to get accepted or rejected. so when you want to be president. or somehow want to. have to be right to be for us this is what before three of them can't be good get.
3:33 am
interested in the water. there soon. in two thousand and sixteen the panama papers show the world with a tax haven the secrets to trailing and united states dollars passed through most. in the amount of time that we've been in panama papers exposure that's what it shows a lot of money it really is. journalism it's an act of journalism looking at things that people want to keep secret and asking why would they want to keep these things secret. millions of most fonseca don't humans were examining. all the people we basically have tried to get an advantage out of this sort of newspaper. and probably other politician which was. other politicians the media
3:34 am
would point to find their targets such as the kings of morocco in saudi arabia the president of argentina several prime ministers. and russian president vladimir putin the coolest. oh my god i've had so i have sued so many newspapers for defamation some things don't just happen by chance it was very striking there were no more americans until this special but a lot of people from the brics countries specially brazil russia and china that this special project reveals what was missed in the media coverage. the panama chronicles. all see we have a great see we need to strengthen before the free flow and you're better than a legend to keep it so it's at the back.
3:35 am
in one thousand nine hundred two that must qualify for the european championships at the very last moment no one believed in last what we won and i'm hoping to. bring some of that winning spirit to the r.c.t. . recently i've had a lot of practice so i can guarantee you that peter schmeichel will be on the best fall since my last will call him the less. than zero zero zero zero zero. zero zero left left left more or less ok stuff that's really good. that.
3:36 am
i. feel. welcome to sophie and i'm so sweet shevardnadze space is endless was the myriads of stars out there chances are that we're not the only ones alive and it's a vast expanse but even if that's true should humans really be actively searching for extraterrestrial life. well a bit of downfall of our civilization or the opening of a new rider iraq will talk about that today with dr douglas back to president of messy messaging extraterrestrial intelligence organization.
3:37 am
surrounded by dust and radiation earth looks slowly hung up in the middle of lifeless space yet with dozens. billions of earth like planets potentially out there humans are determined to find extraterrestrial life. how likely are we to garner a response to messages will be mounted to space. aliens to get our signals to say they will be a danger to earth and could first contact the opening of a new era for the planet or the beginning of a. dr douglas come to the show great to have you on our program so your organization matches focus on sending out signals aimed specifically at aliens and you say that extra terrestrials need to know where ready to communicate but are we really ready to communicate i mean look at us we can hardly communicate with each other. it's true communication is one of the big challenges but it is also
3:38 am
a defining feature of our species that we are the intelligent creatures who love to talk with one another so our work in many is a natural extension of that desire to communicate but instead of talking with other human beings we're reaching out to life in the universe your colleague from they search for extraterrestrial intelligence is huge sas shostak predicts that we will find intelligent alien life within the next twenty years you said that it will happen by approximately twenty thirty five watts in this next twenty years exactly well one of the things that we see in our research is the need for computing power we gather tremendous amounts of data from space and we sift through all of that cosmic static looking for radio signals that stand out as distinctly artificial and that requires tremendous computing the great advantage that we're having right now
3:39 am
is increases of technology so as we look at the advances of computing power you know you can get a personal computer that's twice as powerful as the one you bought a year and a half ago for the same price when that accelerates over the course of year after year after year that gives us a huge advantage today as searches are over a trillion times more powerful than the first search conducted in one nine hundred sixty and we can continue to see that acceleration so within the next twenty years we will have looked at maybe a million stars that's a reasonable number to look at in order to actually find a signal if they're out there trying to make contact could be that we still haven't found any aliens up because technology holding us back but simply that other life forms don't want their presence to be known i mean we've been looking at the possibility of not being alone in the universe for a long time why have fun allianz in time i mean if they're out there we could have found them already know. you are raising the question that the a talian physicist
3:40 am
in rico for me asked in one thousand nine hundred fifty when he said where are they and so it's become known as the fermi paradox well one possibility as you say is that other civilizations are out there but they're not talking so maybe everyone is waiting for the other civilization to take the initiative and that's why mattie sends intentional messages just in case other worlds there are scientists searching for signals but they're waiting for someone else to say hello. you know they were a renowned. physicist stephen hawking has warned us about mating allianz and comparing it to christopher columbus meeting the native americans which as we know didn't turn out so well why don't you believe him and why should we ignore professor hawking's views what we shouldn't ignore his views whenever anyone is brilliant as stephen hawking says watch out be careful you have to take it
3:41 am
seriously but what he really has not taken into account is that the aliens that we're afraid of the ones that can travel between the stars could already pick up our t.v. and radio signals that we have been sending out the past seventy or eighty years so there is no increased danger of an alien invasion by sending intentional signals to let the extra terrestrials know that we want to make contact now seti scientists who actually don't like you sending signals to ellen say that an initiating contact isn't science but rather diplomacy to using good doing it is what they majority of people actually want. well i think that in fact sending signals to other worlds and listening for response is a much more traditional type of science than simply observing astronomers are in an unusual position among scientists because they can do experiments usually you go to your laboratory you make some changes you see what happens but astronomers and seti
3:42 am
scientists have to passively wait for signals to come in see if they detect them we're actually doing what's called a true experiment where we send a signal and then wait for a response back now it's true that there are seventy scientists who have said this is a very long term project most said the scientists want to focus on a search that could pay off tonight but in addition to those seti strategies which our organization also does we also have observatories in panama in the united states that were looking for signals from extraterrestrial but in addition to this potentially short term payoff of detecting the signal we're also making a long term investment by sending the signal and then waiting for a reply that could come in many years from now present nasa has voyager it with just recently fired up its thrusters for the first time in thirty seven years floating outside the solar system with
3:43 am
a bunch of cultural messages it brought to extra terrestrials is what you were doing more dangerous than that. no it really isn't more dangerous but the voyager recording is an excellent example of how we want to make contact with another civilization so this golden record has greetings in fifty five languages it has music from around the world and it has a scientific tutorial along with over one hundred pictures of life on earth so it's an attempt to give a snapshot of earth to another world there's one big problem though of the voyager recording that it travels so slowly so that it's going to be seventy thousand years before the spacecraft comes even close to another star but by sending radio signals the travel at the speed of light we can reach the nearest star in just over four years so there is a tremendous time advantage of sending in electromagnetic signals whether they be
3:44 am
radio signals or laser pulses as opposed to trying to make contact by a spacecraft so how do you make sure that extra terrestrials will interpret our signals as an invitation to communicate rather than a challenge. well the most important thing about sending the message out is simply being clear and any civilization that has been through this process know that there's going to be some ambiguity so we can expect a certain amount of reservation on the part of the extraterrestrial is that they will see what patterns we're sending and try to make sense of them and so that's why we start our messages the first messages we've sent by a focus on simple mathematical and scientific principles to make it as unambiguous as possible that we're talking about what we and the extra terrestrials have in common an understanding of our physical universe all right so he's you are saying that our radio interview signals are ready in space could there be like ellie is watching jerry springer reruns out there somewhere right now awake way to years
3:45 am
away i mean if they base their understanding of us on our t.v. man i mean we're in deep trouble exactly i couldn't agree with you more that in fact we do expect if there is a civilization just a tiny bit more advanced than we are that they can already pick up jerry springer or any other sitcoms interview shows the nightly news they see what we're doing to our planet you know it isn't really a very pretty picture and so in addition to sending in this chaotic messages that we use to communicate with one another we want to send a clear.
