the dreams coming through, making money. having a sun when not feels injunction stops september 19th on d. w. the. the ancient pyramids of the maya, what time piece is made of stone. the massive temples except the movements of the sun forming a precise the calendar. this method of american civilization was very advanced in astronomy. how did the my i know so much that to me, coming out from the dw science, i welcome to you tomorrow today since time immemorial, the night sky has fascinated humanity. even today we still look up whats in our quest to understand the origin or future of our world. technological progress has

changed our understanding of the things we see. the sky is no longer the stick on and yet we still influenced by the discoveries of ancient civilizations. like the maya of central america, they left a unique legacy in the shape of this mysterious document compiled by maya and astronomers. what could it still kind of today? the sophisticated hieroglyphics reveal the accumulated knowledge of the maya. when will the next solar eclipse take place? when will venus appear as a moaning star? experts around the world are still in or if the ticket is calculations of the maya basic. so imagine it's amazing that they were able to produce these calculations thousands of years ago. they say, why did they do this? how could they do it if they did? they have computers. it does scopes the uh, my end the day. so until 1492 by north the maya. well,

way ahead of the europeans in mathematics and, and it's going to be 14 hours. it's not clear how the document made its way to your whether it was looted by the coloring, us full cost of unofficial gift. but still the subject of research. what's clear is that the document ended up and dressed in germany. and it still here today, stored at the sexton states under university library. it's one of just for authentic my encoder sees known to us worldwide researches like carlos by john, joy had helped us understand the document known as the address didn't codex deciphering it has a change. the way we see my and coaches. and courtney said that as an authentic, the dress code x has greatly enriched our understanding of my and mythology religion. astronomy on hard mcclintic. it's funds $39.00 pages written on both

sides. the 3 and a half meter long document served as a pocketbook for religious rituals left on the ceiling. okay, today we assume that the tables on the clips is we used to give warning about when a sign up. more lunar eclipse was due. the people were very afraid of these events . this event even goes with the measles really about religion. knowing the proper time to make an offering to the gods, it might have to do with the cure of a disease. a safe, healthy birth to a good problem to the maya were obsessed with calculating on and pointing the right time to do things. they were able to calculate a precise date way in advance and was a full time. a big advantage for them was that they recognize the importance of a 0 and a new account via because to 0, which we can see here very nicely from the sign in here in red between the black

digits. thoughts enables us to calculate long periods of time on the location in con, very long periods of time, even up to our modern day. one example, the total solar eclipse of $8202.00 full could have been predicted just using the dressed in codex. which a very regulatory revealing scientific interest by a desire to be the goal it's, they were terribly motivated to find out the path of toe to ality. the geometry of eclipses a discuss. so the messa american coaches have to have scientific goals. they allow them to see i in order to have a reliable kind of dressed in code x coming to shows how science and religion went hand in hand. not something we see happening much today. but we can all relate to that desire to understand what's happening around us and to compare the end result

is that people develop their own understanding of their lives on the cost models. yet, building to the support from this interest in knowing about the past shouldn't just be driven by curiosity. but a vital need, the better we understand the past, the most solid, the foundation will be the building all future and understanding all present you guys. and then the same, so studying and h and document on looking at secrets can help with our own understanding of the universe. even today. the question is enough timely. what do we see when we study the skies? which will say, what do we capable of seeing? would we be able to recognize extra terrestrial life if we run into it? why is it that we've never encountered alien life forms, even though there are undoubtedly enough planets that could support an extraterrestrial civilization? could it just be down to a room limit tysons the

p c. so that's the way i see it. if we encounter intelligent extraterrestrial life in whatever form, it could be an opportunity, it might not end well, but included as kind of that. but i know it's vision has been described in this book. that sounds incredible for snaked on. i probably ain't 16. 65 succession them were out fishing by hiring somebody when they suddenly saw ships in the sky above them firing at each other. as evening approached, a dock disc appeared above the sky line. it was the city of chicago and to the to the dentist. underneath this is an advanced, pretty expensive camera. we don't have the final events in it yet, but this one's enough for our tests that covers

a large part of the sky. get them to the fact, obviously a little bit. so for you, cuz maybe they just drank too much or smoke some things. cuz of course, it could also been something like a mirage. i need to speak and those days, such a normally is often seen as miraculous designs from gone scripts, your window size, especially small. it's within studies. extraordinary celeste and events throughout history to try to understand what they were fucking guy on is looking to the unusual in the skies today. to know of him on a place called hatch. donovan in norway. the number of lights were seen repeatedly during the 1980s. they couldn't be a good land, it's still not completely over him on roughly once a month. they were citing some this guy so so here we'd have a better chance of detecting something to, to the gym. what could and cook, these lights actually come from intelligence extra terrestrial beings to assist me if we don't know, she's like,

cancer related. ours is. we have to work with an open mind collecting data evaluated scientifically and then see what comes out of middle school. in 2021, the us intelligence services published a report on a series of aerial phenomena that couldn't be explained is what if one says they were recorded by various parties using various instruments as a human i in for read and read art sizes, they were also seen by pilots, but still they can't be explained. and so i think these cases are worth investigate . i don't listen to them. but actually a task less money, we tend to explain the things we can't understand by assuming there's an intentionality that is beyond what we're able to imagine him 16th. there was no different than the 17th century of document to people believe that anomalies in the sky stem from a higher intelligence. if so,

we're not extra terrestrials but gone into it against just outside of this chapel court. but the alien life isn't thought improbable. according to the so called drake equation, all galaxy alone ought to be teeming with life, with a 100000000000 stones and the milky way of like turn it on even intelligent life phones all probable. in 1950 physicist on rico, sammy aust, why haven't we encountered anything once they re explode by nasa? scientists is not of a great filter that brings disaster to each civilization before it can make contact with other it's the nuclear. we'll artificial intelligence, climate change pandemic. it would seem there's no shortage of options where all progress could lead to all destruction. that's hard to i think there's very use on like i use some civilizations would undoubtedly overcome the filter and then make

contact with the others on done in contact with them. and then ultimately will humana, to be one that survives we don't know if i get, it's not here this. the question is, of course, if there is another intelligent life form, is it close enough to us in terms of evolutionary history? so we can still present it as intelligent in the chipmunks living 20000000 years before our time for which we defended pharmacists. we would not have recognized those as a special anomaly. and it's, well, when it's inside of it, it's gone. this to us we would have been like the equivalent of a tree, a crow linden, a flower, or a cloudy inconveniences. unit balm, typically, i mean depending on where it does high ste. yeah. so to these life forms already be the reason which is not recognizing them with current technology, which we've decided is from new. yes, it's quite possible that because of our limitations, we're not able to pick up on communications and or even movement because we're not

going to position to be able to search by that one's pull, tattooing scuse, and so forth. and thinking about getting this done as soon as can i please help me if i sign with some of the costs. it could also be something where terms like technology just don't apply for like or category like intelligence. as we understand it, that doesn't apply to all the others, guns, and these are all very specific and even criteria for our observations, bottoms for some of which have only a mode in the last century or 2 that's 5 on the job in installing some sense. for the audience story and it's clear that we just can't help, but interpret old anomalies according to current thinking and understanding. in fact, we often don't even realize how limited our knowledge actually is. hack on kyle, at least once to do old, he comes to push back a covent invitations in. what we're able to upset is he's setting out of service stations where recordings can be made in parallel using a wide variety of instruments. even possible,

changes in the gravity needs to be measured off of 2024. he's even able to monitor activity with his own satellite type of guns because the us side. no, no, no, that is a relatively and interesting for various reasons. this is an lungs on the movement is low, it's lean here. yeah. it doesn't make any funny jumps. it doesn't zigzag my, it's not displaying magically celebration. so it's kind of goes to be spill anything it's, it's probably an airplane. what percentage? but what would happen if we did discover aliens one day? why not? so we're going to say coronado and the cost of secularization in the western world . philosophers went to great lenses to free the world of a higher intelligence. pricings, we mounted to you at the top of the chain. the higher intelligence was pushed aside as religious nonsense to god was declared to be dead besides, i think it's a little of a sudden that higher intelligence would be back in feel like that. the students you

it would change humanity and in many ways. yeah, it would produce so many new questions that we'd have to answer. and of course it's possible that the slide forms are simply waiting for us to revolve it as a human race and would only contact us kind of a thing. we're ready to tell them this is the right on what like they do to us with a in slave and exploits us. maybe not. maybe it will be the aliens who save us from our own destructive drive and help humanity survives the great filter. one can only hype this alien life forms came to us. the 1st thing they encounter is all the satellites will, between all planets around $10000.00 active satellites. accommodate positions around us. not to mention the many defunct ones. one view it from gemini had a question about that of what happens to space satellites when

they're doing commissions. the satellites need small amounts of fuel to align themselves and maintain their position. when that fuel runs low satellites are d commissioned. how they're disposed of depends on their orbit satellite circle the earth at various altitudes depending on what rules are designed for environmental satellites. for example, more but a few 100 kilometers above the ground in low earth orbit. navigation satellites are much further away there at an altitude of around 20 to 24000 kilometers in medium earth orbit. satellites were telecommunications, broadcasting, and weather forecasting. our for addition from the air in what's known as geo stationary orbit. their position above the equator and are always focused on just

one part of the years. after their mission, the satellites are blasted into a graveyard orbit. it's located around 300 kilometers above the g o stationary orbit. this area is now densely populated. once a satellite is reached, the graveyard orbit, the control center must empty its tanks and drain the batteries to prevent an uncontrolled explosion through the fuel igniting. for example. satellites and low earth orbit are brought down in a controlled way and disposed of in the earth's atmosphere. be increasing frictional heat causes them to largely burn up with the remaining debris falling into the sea. satellites may also be damaged by media rights or space drunk and have their lives ben short. they can no longer be controlled. researchers are now hoping to recover them using risk q satellites. they'll either grab hold of the defense spacecraft or capture it with

a net. the aim is to bring them down in a controlled manner. the european space agency asia is now preparing for its 1st disposal mission. to clear space one let us read. why do you have a science question for us? send it in as a video, text or voice mail. if we on switch on the shows, we'll send you a little surprised as a thank you to go on. just ask in june 2024 attorney's pretend from the mean. it was the 1st time that the space probably had collected well, can soil samples from the fall side to, to me and brought them back to us. so now i'm to go in detailed analysis. when it comes to lead new exploration, china is leading the way from

this we always see the moon from the same side. this has to do with its rotation. the us apollo emissions in the 19 sixties and seventies landed on the side facing via they left with hundreds of chinos of moving on to study. china has already managed to land on the fall side of the moon twice. and it's telling me 6 mission has now even managed to take soil samples. a huge success landing on the fall side of the moon is especially complicated of the moon. the obvious fix that has been various landings on this side of the main. so the side that faces it does come on for, for you can be track from this practically in real time as a delay in the signal of one second. also, they might know if you lands on the fall side of the moon, you don't have direct connection missed so you have to send such

a light that would cause a radio bridge if you like that you'll break it and so everything gets more complicated. not typical at the beginning of june, the chinese prove less the moon bringing the lunar samples back to the scientist one to analyze how the 2 sides of the moon defy the cross. the sheet is i biggest difference is that there's more love on this is the oh is side of the mean, me alive off the oldest like a full kind of lava that was admitted millions of years ago. it involves to comment is the lava and all that comes out. it own it says it is i to about means the samples from this side. so i read it simply need active noise. the over fixes such as the moon on the fall side is different. probably of the song loss from the a very much original samples of the lunar surface. it this morning we don't, china wants to explode the moon, not just we've proved, but also with us to notes at the end of this decade aging times to alonda crew on

the moon on set up a research station alongside the us. china has become the new leader in space expiration. russia postpone and behind. the district technology that the chinese have developed is based on russians or knology from the 1970s by the but they've advanced it to such a degree that it no longer has anything to do with russian technology. it's in fact just the chinese now monk profession, space technology. not completely independent that i can for these who will put a crew back on the moon, 1st china, all the us with the awesome is program. the americans are planning to get national spark on the moon. before the chinese do, and this is where the european space agency isa comes in. unimportant module of the optimist. a ryan space cross comes and here it, it will help pilot a ryan. the europeans are working closely with the us on the program. but

a so say what with china on the current chinese 6 mission producing one of the instruments on board. the luna approved the green square monk's exposition. the instruments have successfully measured negative ions on the moon. however, it seems unlikely that you still will continue working with china, especially given the success of staging chinese emissions. as in pull the items they work is more preparing for the chinese landing a crew on the new one that puts china in competition with the american on this. i guess the americans also want to land on the moon in the next few years. now the easter has joined forces with the americans for landing on the moon. i think that's why the us is saying, did you say if you want to do moon landings with us, then stopped working with china. what done to that machine? that was china's goal and all this, while the american see the moon more as

a stop on the way to miles little responsibilities. china has other interest vehicle including you to educate young people uninspired. then when i'm secondly taken to promote technology, and if you look at the find your on it states, clearly we need new technologies on space. travel is a driver of technology to us and to motivate young people. and that's why they're doing that. it's really expensive, luna programs, you know, they want to cover them in which satellite you find lots of communication, satellites, moon observations, on landings, more robust one feet and more than one chinese 6 is just one. stepping stone on china. is jenny to the moon? only a few decades ago that the fastball kits were launched into space a short while later on the most. so i put some for to cruise they could come back on homes. monkeys sitting in american rock hits, small monkeys,

but not as small as a great type species, but once populated itself in germany. as a recent fossil discovery were, feels less than one centimeter in size. this tiny little tooth belonged to a great 8. it lived here 11600000000 years ago in fox and in germany southern outgoing region. since 2011 researchers had been uncovering ancient remains here, like this vertebra from a prehistoric angelo. during their 1st excavation, they found to fossilize chief and didn't meet cap from a great deep. but because the finds were so small, the experts assumed they were from a small old world, the monkey diesel. off on the boxes, the monkey species we expected. we knew they lived here at that time height, so we thought that's what we found it out of yet. but when they found parts of the

skeleton of another great ape in the same place in 2017, they began to have doubts. because this one was clearly agree dates. daniel, the school can mosey, was significantly larger. the find drew global attention because the large primate could already walk upright at this thinking back center for human evolution, the researchers then examined to their earlier find more closely the small teeth than me. cap revealed the animal 8 leaves and weighed just 10 kilos. that makes it the smallest great shape known to date as well. so i just thought it wasn't so easy to prove that these 3 objects came from a great time for the new cap. was an easier because i had atomic lee very similar to modern great games yet to tell you what we had to do. very detailed examining sions of the teeth so that other experts would believe that this is a great a,

that's a small as an old world, the monkey in klein. i type stuff. but it's not just the size that makes this fine . so special. discovering fossils from 2 different species, upgrade 8 living at the same time in the same place in europe. this is a 1st this is vicky. if we don't use something special kits and cannot mostly use it the 1st time we are fossil everything that is to gradient sweet shoes go existed . we would never really expect you to find them in this region who because since you're comb for heck is active because 11600000 years ago. but the southern germany is thought to have been covered with mixed forests, which wouldn't have been ideal for great, a mystery that further discoveries may eventually solve. and that wraps up all johnny into the past. the future, even going to the mean and back. whether it's pre historic gates aliens,

or the ancient maya civilization, there's always more we can learn about how well i'm the galaxy. thanks for watching and see you next time the the
