the n she disappears without the trees. secret type queen has been accused of due floating victims on the top 10 list, the cartel leaders in murder is a financial thriller about the world's most wanted woman. crypto queen stops december 30th on dw radio telescopes, and house to listening to what's going on in the states. they search for signals that originate many light years from us. with the help and international research team has now discovered a new form of gravitational ways. it's certainly in recent years that we've been able to imagine such waves directly that and coming up on tomorrow today. welcome to the dw science show.
11:31 am
we have detected gravitational waves. we did. it was in february 2016 of the research and succeeded in detecting a gravitational way for the 1st time produced by something that was long considered impossible. in 2023 research is that the mustang institute for radio astronomy, the chief, something no less spectacular. for the 1st time they discovered not showed, but very long gravitational ways to measure them. they needed a device that is larger than the much larger forces into many is a research instrument is essentially the size of the milky way uh, when we look at light source described across the galaxy that are hundreds to thousands of light years away from these light sources that we called pulse are just, and we try to use our method to register the fluctuations and the distances to these and close our engine, it puts out and then to it gets to them the size of the milky way compared lots to
11:32 am
a tunnel. several kilometers long, which was low enough to detect the 1st limitation of waves in 2015. this total was compressed and stretched by less than the diameter of an atomic nicholas and the whole process lost it just a few seconds. short rotational waves created when 2 black holes over each other and finally, much only for a few seconds saw the resulting gravitational waves powerful enough to be registered on this. but back in the 19 ninety's, michelle tom and his colleagues set out to discover a completely different type of gravitational way, the gravitational long way. it was anything but such and that they would find it. but they had a legend re telescope to assist them. the f of book radio 10 escape in germany's western eiffel region, measuring a 100 meters across its been in operation for decades. updated continually on active and searching for gravitational long waives the physical therapist by the
11:33 am
telescope and apples. america has provided the longest data set and worldwide in this experiment it happens that most if we've been recording data since 1995 and monthly and weekly intervals, and that has never been interrupted. and so it forms the backbone of this experiment, at least at the european level. if not world wide sites have been shred for the actual stake. radio telescope looks best special stars, cold poll phones that emit radio light waves at regular intervals like a lighthouse for a long rotational wave passage between the stalls and the telescope. over many years, the distance between us and the style changes delaying the lightweight. so rifle on it, that's how the long gravitational waves were discovered. that created when to super massive black coals over to each other, the mass is billions of times greater than a sun. the spots in this interview, the black holes that we look at have orbital periods of 10 or 20 years. so in order
11:34 am
to be sure that what you're seeing really is such a system, you have to absorb it for a long time and angular type. we call it detection in slow motion with i. e. our signal builds up slowly and becomes more and more significant. all right. and you have to be patient to come and look long enough until you are sufficiently convinced and that the signal you're seeing is really real. that's why when will happen something. now this one is the toughest, isn't for you all is the essence. but i'm kinda, it's powerful but not sufficient. tony. so a whole net lists of radio telescopes was organized across here at this network is now listening in on the black coal smoke talk, so to speak have nice as a medicine. so i like to compare it to a cocktail tardy and tom is to so you have couples talking to each other all over the place, the, the white homes. and then there's that general home of conversation throughout the room and comes in a group is quoting a couple of years ago, and we started hearing something from pa, yeah. now we know that systematic,
11:35 am
we see that there are people talking with the we can't get distinguish all the snippets of conversation stuff by law. it is in but hopefully in a few years time will be able to discern some of the conversations and pion come i got a bunch question and things question. in addition to the esl spec, telescope is the most important part of the european network, studying gravitational weights. similar experiments are underway on other confidence. in june 2023. they all and failed the results with a buying the long waves where identified now that being studied we knows that the universe is expanding. but how is that happening? that's one of the questions that the new european space telescope euclid aims to onsite launched in july 2023. its task is to create a 3 d map of i'll come from off cape canaveral on july 1st
11:36 am
2023. a textbook launch of a space, x rocket, caring the you could tell the scope into space. the points at which euclid was to begin its precision measurements was one and a half 1000000 kilometers away. that's 3 times further than the moon. steve separation from the 1.2 ton telescope pieces away from the earth and the sun shield protects it from the heat of the sun's rays. keeping the telescope cool, and protected from bright light helps to obtain sharper images. the primary mirror measures 1.2 meters across and allows euclid to look at galaxies, up to 10000000000 light years away. it will be studying dark matter and dark energy, which influence galaxies under causing the universe to expand ever faster. dark matter is invisible, but can be observed by its gravitational effect on galaxies. you can,
11:37 am
it is very special because this camera will have such as precise accuracy in terms of how we understand the way the camera. what is it will actually be able to measure the shape of the galaxy? i'm, we know the gravity. i just need to store the sites of galaxies. and so we'll be able to understand how my affects galaxies and expansion. euclid will take several 100000 images. precisely, mapping out around a 3rd of the cosmos. the cheaper the telescope looks into space, the further it can see back into the past. so the photos are not only a current snapshot, but also the document how large structures in the universe developed, including galaxies and galaxy clusters, as well as the vast filaments of dark matter that draw them together. their dynamics will provide information about the dark side of the universe. euclid is
11:38 am
tasked with answering 5 questions. how is dark matter distributed throughout the universe? how did the expanding universe evolve over time? what does that tell us about the characteristics of dark energy? has proportions of dark energy changed over time? how does the universe is large scale structures form more than 3 and a half 1000 people from 21 countries are working on the euclid project. the european space agency or essay is over seeing it. the 1400000000 your own mission should give us a better understanding of the universe. the quality of new clips. first images has been impressive. the photos still won't tell us what dark matter actually is. but knowing how it's distributed in space will provide an important basis for further research into what is probably the greatest mystery of the universe. hundreds of scientists now
11:39 am
eagerly await you clicked insights into the cosmos. it will then take years to analyze the data and now of it to you, do you have a science question? send it to us as a video, text or voice mail. if we answer your question on the show, we'll send a small gift as a thank you. this week's question comes from daniel fernando. as in colombia, can you see this dogs when the surface of the moon on a clear night air on is the sky is liquid with countless stones. but if we were in a big city, we only see a few because our surroundings are too bright. it's the same when there's
11:40 am
a full moon on its light out shines everything else if we're in a job paste, on the other hand, we see many stones twinkling. that twinkling is caused by the is i see when the starlight passes through the atmosphere, it hits names of different temperatures and is diffracted. the moon has no atmosphere. that means the night to the sun shines on him to the surface, illuminating it bright be. but areas in shadow remain extreme. the dog, historical footage of minds missions to the moon, show the apollo, asking also against the backdrop of a black sky, a sky without stars. that raise questions about whether the estimate what should really be to them in or whether the whole thing was staged much
11:41 am
later that could be a space proved also showed up black sky. it's simply because the earth and the assistance of the moon is so bright. the cameras couldn't pick up stones just like in the city with most of the stars and no longer visible. the in 1972 as to what's on the apollo 16 mission photographs, the earth and this guy from the moon, in ultra violet light. the images are listed with bright, don't saw stars, so they can be seen from the mean. and you actually have an unobstructed view of them. just like on the international space station, which floats above the s, it must be it. so for that reason, the stars don't to pay to twinkle like they do down here on the will we always have in us from which we can gaze at the sky,
11:42 am
given the mold and $12000.00 nuclear weapons that still exist worldwide. it's a legitimate question. we haven't even managed to achieve a hope to meet the weapons testing. we can monitor this easily, thanks to a well like network of measuring stations that register every kind of test we visit one such listening in germany. the facility is located close to germany's border with the check republic and austria. lar serrano from the institute for geosciences and hanover, comes here once a year to do maintenance work station was built in the 1980s to monitor the soviet union, nuclear weapons tests these days. the focus is on countries like north korea and china. this is a steam, is it in the x, these systems can i don't, if i explosions very accurately pinpointing their location and measuring their
11:43 am
strength. wisconsin, his theme of this thoughtful, diagnosed with sex, noise is detected and a den, a fide every an authorized test since 1996. and you can see it in the surroundings is very and forest shops like this one, conceal size, monitors. opening the chef is strictly forbidden, under normal circumstances, but today these devices are switched off ready for maintenance as they are located at a depth of 5 meters on granite rocks where they can detect even the smallest tremors into horizontal directions and vertically messing yeah, within we have $26.00 sized monitors here, measuring tremors in the earth, and the 5 then we saw of an earthquake or explosion occurs somewhere in the world is what it will limit vibrations to. and if those vibrations are strong enough, they'll be picked up here that the last nuclear weapons tested north korea released
11:44 am
vast amounts of energy. just like in an earthquake. the tremors travelled quickly through the earth's core and more slowly along the surface. after just 11 minutes, the alarm sounded here in hand over at the german government's 1st quake center. this is where the signal is from the measuring stations and the variance, forest, and elsewhere are recorded. the strength of the tremors and their precise location can be pinpointed exactly when they start, because if we had a powerful size more logical event right now, we would see something like what we have here indicating perhaps weaker events. so we have a horizontal line here and what this means that all the stations registered a lot of energy at the same time. it's back to the measuring station and the variance, forrest state of the art in for sound systems are also located in the surrounding woods. they verified the size make measurements with additional readings. these
11:45 am
instruments are well hidden, so lar serrano has trouble finding them look upon their so well camouflage. to come on. you can only see the individual measuring points once you're standing right in front of them. 100 some it's vivian. so even we who know where they are, can't just spot them in passing. as each one comprises $96.00 steel tubes lying on the ground and pointing in every conceivable direction, they can detect the smallest changes in air pressure, such as those caused by nuclear weapons test. this is open an eye lesson using these inlet. we measure the air pressure at this point here, this, this air pressure say don't then pass us through the stainless steel pipe system. we're measuring low frequency sound here. so that's in for sound waves that humans can here with frequencies of 4 hertz or less, sometimes for up to minutes at
11:46 am
a time. a vision for sound waves, because they have such a low frequency can travel over a very, very long distances. so tens of thousands of kilometers the solitude and tranquillity of this border region make it an ideal locations for the measurements . they take place around the clock. underground tests are registered just like earthquakes. seismic events are recorded and analyzed by over 300 such measuring stations worldwide. and it's not i constructed. so if an event takes place, we have for 5, or even 10 or 12 of these measuring stations that have picked it up and bail showed the direction it came from. so we can locate where the cross can pinpoint the location precisely no test the. the last underground nuclear weapons test carried out by north korea in 2017 triggered a quick, measuring 6.4. on the richter scale in the past 25 years, only the united states,
11:47 am
india, pakistan and north korea have carried out such tests. in theory, they're banned by an international treaty, but it's never come into force. still. lar serrano believes it's important to monitor these activities and make every tests public existence theme. uh this system makes our world safer food. when placed about it's making a significant contribution towards one day having a world free of nuclear weapons, diabetic. and, and even if you say the cold war, which used to be your motivation is over. it's of course still an important color of global security policy. yeah. especially in today's world that globe binds the sides pretty take and it could become even more important if some countries, once again, start testing nuclear weapons. due to note that access to quantum computers is, is as restricted as the trade in weapons,
11:48 am
great new material. this is to ensure that quantum computers don't fall into the wrong hands because the technology is set to be able to crack all encryption codes worldwide, should it finally function is intended. that's one reason why many countries are investing billions to finance the development of this technology with china leading the way by 2020 to aging, had some $15.00 us dollars into quantum computing. other industrialized nations, our olson investing heavily. but how did these machines actually look at says loans, quantum computers look more like a non refrigerated barrel, not exactly spectacular. the secret lies within a quantum computer has to be kept incredibly cold. print superconducting components to work that code quantum date so cubits the show. they need cooling system,
11:49 am
laser pulses on control technology. a computer like this will probably never. grayson office desk, but it's cubits can do way, mold and conventional. but normally these computers are kept under lock and key ibm research center in switzerland. we get to have a sneak peak at one's name authorization, other k. now. so this is a quantum computer. that's that the moment it's cut, it doesn't have a processor on it right now that you want me to input and then that will be loaded from below. to then is the actual quantum processor ask us mix, see what you see here, and see what is the refrigerator capable of cooling down to what we call absolute 0 toyota, which is minus 275 degrees celsius. stop and say the seals and foss, new tubing. this helps to shield the processes from outside influences. to understand of quantum computers. what you have to do is deep into the world of the smallest particles,
11:50 am
the item. it's the world of quantum mechanics. a strange will nice, disturbing wells. that's fascinating to here. everything is constantly in motion overlapping on, often in several places at once. it's hard to growth quite literally because as soon as you try to measure something here, the quantum states dissolve. so you 1st have to learn how they work. in the past, we will only familiar with conventional bids, which are electrical circuits with transistors that can either be 041. this digital well can be wired logically. what each circuit is processed in sequence one off to the other very quickly, but always one off to the other. in the quantum computer bits become cubits. they can be manipulated by a microwave or laser pulses,
11:51 am
thus described many most states of and just one or see right. in the so called superposition, the cubit and can be one on 0. but the same time an old states between the it's rather like a spinning coins. as long as it's spinning the decision is open only when you measure this the cubic use one of the 2 conventional states. unacceptable will help illustrate what this means in practice. a computer results to find the most direct cost in a complex system. a conventional computer works to old possible pulse, one of to the other. the more complex the task, the longer it takes, a quantum computer with its connected cubits, can try out all the possible path symbols heinously, and still find the best route much more quickly. but it says i can the so now you've learned about 2 important properties of the quantum computer. technically at
11:52 am
1st, the superposition law that you can be in 2 states at the same time on coffee. but the other thing is with it. and if you have more cubits, and this leads to an extreme increase in the number of possibilities that you can look at simultaneously, i'm going into the cloth. this is called quantum parallelism going to be on. and that makes the quantum computer is very powerful and very fast. i'm off this now, what are the possibilities of this quantum parallelism iris standing? so one cubic in superposition can describe 2 states simultaneously, a 0 on a one with 2 cubits. that increases to full state the combinations 0 and 00110 on 11. each additional cubic doubles the number of possible civil, tiny states. so with 3 cubits the 8 combinations. with full
11:53 am
it's 16. it increases exponentially. a system with 10 cubits can already make use of 1024 states. symbols heinously with 20 cubits. that number rises to over 1000000 with 33 cubits. you could execute operations on most states, and they're all people on this. with a $166.00 cubits it's mold and all the items on s, on with the $279.00 cubits. you could work symbols, heinously. what about as many states, etc. thought to be items in the entire universe, 971 step to invite intel in an unimaginable number with a to 7 digits. so quantum have a lot of them, makes extremely complex computing possible. but what could quantum computers best be useful? stuff? i'm good or a specialist in quantum algorithms says that's suitable for highly complex
11:54 am
simulations with almost and this possibilities by speed of the examples could include carbon seek restrictions. so is this extends to the development of synthetic fuels for state are we don't know how to make them more energy efficient estimating. so the examples often relate to energy efficiency. and this kind of that concludes the development of new catalysts, or a better understanding of chemical processes than all other examples include the development of new drugs that work better and maybe can have a more targeted effect and fewer side effects, for example, that in the long term that's a possible application that could have a huge impact on society to this claim. and i was off because that tough problem taking the example of medicine. imagine every person receiving their own personal medication tailored to the illness. and to them, quantum computers could calculate what that would need to look like. for agriculture, quantum computers could make farming green us by helping to optimize the production
11:55 am
of ammonia making the production of fertilizer more sustainable. and in the just fix, initial experiments are already underway. in the extremely busy, potent los angeles, quantum like systems have optimize the handling of containments. that's helping to save a lot of money on results is so phone. quantum can be to austin evans and see. but that potential is huge. we imagine about science and technology. that's like dw signs is now i'm take time. what do we do for fun? why do gravitational ways that that is when the people begin getting high and laughing gas out? the drums boogie to the beads. and what's the perfect kid football find?
11:56 am
find the on says gets most c w science. oh, new tick, tock, channel. and that's safe for today. thanks for watching tomorrow or to date. the dw sign to see you next time the, the, the
11:57 am

11:59 am
tracing the see the history of every day. ok. and that's something right around the world. kind of cool. so taking the juicy of stories with a little mystery of drama along the way. but no need to talk about i just said subscribed already listen to process and will take you along to the right side the
