Very common question I’m seeing here, and indeed honestly a very common question students have in my classes about statistics, is what if one of the oldest civilizations applied this reasoning - wouldn’t they get a totally different and wrong answer? Yes they would, but that’s how statistics works! Not everyone is guaranteed to be right every time. The oldest civilizations in this scenario would be the rarest and thus although they would arrive at the wrong answer, the majority of the sample would arrive at the correct answer. Think of it like this - if you state there’s a 90% chance of an event occurring, you will predict the wrong answer 10% of the time. That’s not a failure of statistics, it’s intrinsic to how it works as everything has uncertainty. All we can do in statistics is make *probabilistic* statements e.g. this is the most likely outcome, or this happens 90% of the time. Challenging to explain this in a single comment, it takes students a long time to grasp this concept usually but I hope that helps!

He said, “grab a cup of tea” so I paused the video and did just that! This channel is vital for great ideas.

Since I was a kid, I've found astronomy and the possibility of life outside of our solar system to be fascinating. From an auto mechanic in southern Indiana, I thank you for your content. I am making my way through your library, and just cannot get enough, it keeps my dreams of the stars alive.

The "Dark Forest" theory could be a reason we haven't heard from anyone...Maybe everyone stays quite because they fear the other "hunters in the forest"...It's safe to say in order to become the dominate species on a planet one would have to be a super predator like us. I'm not saying aliens will be the war mongering invaders we see in movies, but they might also not be like the trope of the highly evolved above using violence type either. They may be just like us, an interesting mix of beautiful dreams and horrible nightmares.

Among all the crappy channels, you stand out as something very different. no ufos , and ancient alien nonsense. Thank you for intelligent content

Legend has it he's still out there liking comments.

"Hunter-gatherer society floating a message to us down the river on a piece of wood" Isn't that similar to what we attemped to do with the Voyager probe?

A bit of an odd consequence of this approach, is that the older we get, the older we should assume other civilizations should be on average. I guess that makes sense, since if we are observing our own civilization survive for longer and longer periods, it would be the safest bet (but of course, only a bet) to guess that other civilizations would be tend to survive for that kind of timespan. Here's hoping for a long-lived humanity, so other aliens out there can enjoy similarly long lives!

We may sit in the middle of a graveyard of incomprehensible scale, the only intelligent beings alive at this time. There may have been thousands of intelligent civilizations before us, and billions to follow, but in the vastness of time, each makes its journey from cradle to grave in complete isolation.

Aliens probably lock their doors when they fly near Earth.

The most obvious reason we haven’t contacted another civilization should be obvious - the universe is unimaginably large, and our understanding of physics only allows us to reach a fraction of a fraction of our cosmic neighbors let alone the Milky Way let alone the rest of the universe

I'm working my way through your library. This was amazing, and has started conversations with people around me that have not even considered these questions. Thank you for your time and effort.

worth mentioning regarding the lifetime of civilizations on Earth: the end of a civilization didn't always mean the death of a group of people; sometimes it just meant the same group of people scattered or were under new management. Maybe the data ought to be revised to account for actual extinctions of groups of people

Narrator : Sit back, have A cup of tea with me. Me : LETS DO THIS... *While having a beer & smoking a joint*

I know that Cool Worlds would rather be studying a catalog of discovered exo-moons, but the time being put into this channel is a great gift to all of us viewers. Thanks for the awesome content.

This content is truly amazing. Having a professor/researcher making videos explaining the incredible complexities of our universe is truly astounding. Whenever he speaks, it's like a cascade of knowledge so well-worded and passionately delivered which is admirably poetic. Honestly, this is an honor. I'm quite passionate for astronomy and this is incredible to me. Probably the greatest channel on KZfaq.

This channel is amazing. I randomly found this channel one day ago and I am hooked. Your ability to merge the technical aspect of science with the romance and beauty of the universe. Well done!

Absolutely loved hearing Carl Sagan's voice again. As a young boy, he sparked a true love of astronomy, and the philosophical pondering of many deep ideas. Hearing his voice again, really brings me back in time....

Searching for alien civilizations via radio is like a drunk looking for his keys under the streetlamp. It's where we can see.

There is also another variable to consider with the longer-lived civilizations. If they lived long enough to create the technology to transcend the planetary boundaries and spread to other planets, then they would no longer be susceptible to the vagaries of a planetary catastrophe. Thus, the longer a civilization exists, the more it has the potential to continue existing after that point. That would mean that some of the red dots would never fade out and push the probability of a civilization being older even higher..

I've just found your channel and watched 4 videos in a row. Thought provoking, informative, non-judgemental ... by any standard, you have a winner. And a new subscriber. Thanks for sharing your knowledge, keen insight and interesting presentations.

The effect of time causing older civilizations to be more common could be even more extreme when you phrase the question specifically as "which type of civilization are we most likely to find" because older civilizations also are most likely to have spread out among the stars to multiple planets and star systems. Obviously, if they have more territory, we're more likely to run across them (or vice-versa).

What a refreshing documentary on this subject!

If any aliens are intelligent enough to detect or reach us, they're also intelligent enough to NOT visit us due to the risk of contamination.

At first I thought that you are one of those people that like to hear themselves speak. But then I actually watched your videos about aliens. I think you are inspiring a lot of people , like me, that look up and wonder “how the hell are we alone?”. Thank you sir.

Wondering about the T-shirt? We now have a TeeSpring store! (For some the KZfaq integration is having some hiccups but should be on soon). Link is teespring.com/stores/cool-worlds-store

This is what my math teacher expects me to do when she says find x.

This is extremely smart content that you’ve put into easy to understand terms. You have a talent for explaining this stuff. That’s a good sign that you really know what you are talking about. Thanks for making these videos!

When Rishi said "you were right I was wrong" is the understatement of the century

I’ve been following this channel for about a year and this dude are so underrated. You should have millions of subscribers. Share people.

I could fall asleep 😴 listening to this man. Not because he is boring because he is very good at presenting vivid imagery through his explanations. Plus his voice is soothing .

Every time I find a quirk in your analysis, your next words acknowledge it and you provide an explanation to support the reasoning. Absolutely the best analysis on the subject I’ve had the pleasure to view. The next analysis should focus on proximity to those civilizations based on the galactic distribution of sun-like stars in our galactic neighbourhood. JWST will provide a minimum value and we can extrapolate based on volumetric or at the very least rule out minimum distances based on our discoveries.

Just an aside... I find these videos refreshing, enlightening, at times beautiful. Obviously thought provoking. Appreciate you Cool Worlds

It took a little long to get there, but I’m so glad to finally see a temporal view to other civilizations. I’ve always thought the question of IF there is intelligent life was the wrong question. We should be asking WHEN is the intelligent life, and what is the chance any life could survive long enough to be able to find another life form or be found.

If only I had a teacher that explained how interestingly statistics and Mathematics can be applied to space and the unknown… thanks for an awesome video.

Excellent work. My mind is firing on overdrive with new ideas and thoughts related to this. Thank you for the video and please keep up the good work. I will do my best to support for future work.

He said grab a cup of tea, "Explains the powerful truth behind Temporal Bias" one bottle of spirit later & a DMT trip and it turns out that i was already watching this 100 years ago...

"You get the idea...you lived through 2020" lmao

Very, very intersting indeed, as I've become accustomed to from this wonderful channel. Mixing this with another fundamental question of today: listening to the worries from many specialists in the field, there should be a good chance that many of the older civilizations around are thoroughly dominated/controled by AI. Or are even nothing but AI anymore. Now since we only have theories about how a civilization like that would look and operate, I suppose we can't predict very much about its lifetime. But it's very interesting to think about it.

This channel is brain food. I've always sucked at and been intimidated by mathematics but here I get the "gist" of what is discussed. This channel is one of my favourites, thanks.

I think the concept of a Prime Directive (in some form) makes sense for an older civilization to take. The idea of non-interference seems inevitable to me, not because I fantasize about them being morally anthropomorphic, but because the act of not making contact creates less risk potential for drama, war, manipulation, boringness etc... If 'they' are likely to be far more advanced, then their indifference to us and their disinterest in us is somewhat expected. We may even be able to see their worlds, and happen upon some of their ships up close and still be 'cold shouldered' and never communicated with. They might not care unless we were interfering with their interests. I once jotted down an idea for a sci fi story plot. The idea was that a genuinely alien species came from a near-by star say 10-15 lightyears away. This star-faring species was very much hominid looking in appearance, in that they were bipedal, breathed the same gases and tolerated similar gravity/air pressure. They also made audible sounds to communicate, basically a pretty anthropomorphic species. They came to our system and basically started loitering around our moon and even taking up space on two continents in remote areas albeit in small numbers and lightweight ships. Their weapons were not catastrophic but they were continuously being violent. Our attempts to communicate with them and to understand them kept meeting with massacres and human leaders were trying to figure out what to do, considering that the alien's technology was several millennia ahead of humanity and the aliens were showing no signs of wanting to share tech, trade, or even study us. Out of nowhere, a ton more of them show up and begin obliterating satellites, 1st world air bases/missile installations and also killing the inhabitants of a few small South American cities/villages with toxic gas in an effort to annex that geography for themselves. But this is where it gets interesting. Another alien species, completely non-anthropomorphic in appearance and supremely more advanced than both humans and those invaders from Tau Ceti, comes in from Titan (moon of Saturn) and they start whipping the invading aliens butts. The non-anthropomorphic aliens are terrifying in appearance but are protecting humanity. They stand about 9-12 feet tall and are bipedal but they certainly arent anything like a mammal. Their heads resemble an eagle because they have dark beady eyes that dart around and a large ominous beak. They dont speak or make noise beyond the sounds of their devices and tech-suits. They have feather-like skin but mostly theyre covered by the bioengineered suits they wear. Normally you cant make out their face/head because they not only wear helmets but they all have personalized force-fields around them. Later it is found that the force field which distorts light, also disrupts spacetime. The field around their person dilates gravity/time among other things like noble gases, airpressure and temperature. The field enables them to move abruptly and even disappear. Its apparent they like it COLD and must be quite comfortable in conditions that are absolutely inhospitable to humans, "deep cold well below the line" as Ash would say. These Bird Aliens as I call them, wipe out the invading aliens completely. They literally smoke every last one of them in a matter of days. But not only that, they commandeer ALL the invaders' Gen Ships/space vessels/shuttle craft and hand them over to humans as an obvious leg up. We're talking about 6 LARGE Gen ships in orbit, 3 dozen mid-size starships capable of planetary re-entry and a few hundred smaller craft including some land assault vehicles. All the invaders are deceased and all their tech essentially gift wrapped for human reverse engineering. Towards the end, the super Bird Aliens leave as fast as they arrived. Except a dozen of them on one of their ships stays for a few months in northern Russia. The world's best scientists and xeno biologists make slight progress in trying to communicate with the _Berds_ but ultimately not much can be learned because they are so far evolved and superior. The Berds' own offerings, presentations and gestures dont make much sense to us. It is learned though, that they dwell on Titan but are not native to this system although theyve been in the Sol system since well before homo Ergaster roamed Earth 3 million years ago. They presented a crud diagram of Earth when the continents were shifted in the past. We deduced some of their symbols to be an Earth Calendar but the days were off compared to our modern timekeeping. It became evident that they had intervened once (perhaps more) in human affairs following the eruption of a volcano 80,000 years prior on the island of Sumatra. (TOBA ERUPTION). Although its not exactly known from the data we translated, its looks like the Berds relocated some surviving humans during that ancient crisis. Its not known whether they uplifted our genetics at any point but arguments on the topic never seem to end. And then like that, they were gone. The closing of the book reveals an astronomer reviewing James Webb Telescope data, watching a large Berd fleet appearing to leave Titan headed further out towards Neptune but we lost sight of them. No one saw any flashes or evidence of spacetime disruption (as if a wormhole or some fanciful FTL tech was being used) ... they just disappeared. Many Nations are now conglomerating on a mission to explore Titan.

Ok I’m sorry but the people grinding wheat in the beginning. Grinding the whole tassel?! That’s not how you process wheat! Ok mini rant over, probably not your fault, proceed. 😆

This man, has one of the most layered and probing minds, of my life time. An incredible orator.

I could listen to this mans voice forever…. Not only is he giving the most interesting information. His voice is so calming and joyful to listen to I am hooked the minute he starts talking. I fall asleep listening to all his videos … every night. I can’t get enough. Please keep uploading content.

This was very pleasant to watch. The narrator's voice is nice. Good job on the production overall. I subscribed

"You're still half savage, but there is hope. We will contact you when we are ready", A "Metrone", Star Trek 1966. The concepts of empathy, mercy, forgiveness, compassion are an ethereal hazy thought processes we find being "right", noble, correct....but we don't know them fully. It may be that we are fully known by more advanced species, but a specific "hands-off" policy may be in place, so we are not aware of their presence.

You make an excellent point in the end. I'd imagine the first encounters we as humans would make would be far beyond exciting, no matter the age or advancement of the other civilization(or basic animals). As time goes we'll probably start ignoring the "less" interesting ones because there is no gain for us, might not be any worthwhile resources or we just don't want to interfere(which seems more common to us modern humans). As time goes I think we'll eventually end up more toward the latter where we keep our distance as we advance. It would perhaps be safe to assume that older civilizations would be the same way, to avoid detection/contact until whatever it is contacts you directly in some way.

This is the best thing I've seen on KZfaq in a very long time. I have a question though... Do you also have to consider the amount of time it takes for light to travel from other civilisations? For example, if we could see all of the older civilisations in our galaxy and beyond, we'd be looking at a snap shot of the past. Therefore, by the time we'd obversed the civilisation, it would either be older or it might have died out.

11:52 "You get it, you lived through 2020." Best line of the vid!

I rarely comment on videos but I loved this one! from my point of view: older civilizations would only observe us without interact.

I don’t comment much on KZfaq but I just wanted to let you know how much I appreciate your videos and how much I love your channel. Thank you!

When asking a complex question with variable unknowns, I find it helpful to bring the question in to something simple and known. Q. "how should we meet and communicate with groups encountered for the first time?" A. "slowly, cautiously, respectfully until information can be exchanged and a common ground can be found to establish trust, ensuring safety and benefit from both sides."

I would simply like to say thank you for taking the time to make such fascinating and entertaining videos. Wonderful stuff!

I'm happy that you acknowledged the Indus Valley civilization, almost everybody seems to overlook it!

Being someone very interested in sound, there is a documentary here on youtube asking the question: "how would we recognize an alien signal?" A "dolphin scientist" had experiments saying there are patterns of most to least used sound in every language on Earth. He tested to see if the pattern appeared in dolphin sounds: it did. maybe could work for alien transmissions. Doesn't show you what they are saying, only that it really is a language.

I quote the simple phrase of yours which marked me years ago and made me love your channel: "We simply don't know".

“You get the point, you’ve lived through 2020.” I like this guy, a lot. He’s sharp, and keeps my interest. Subscribed!

One assumption made in this discussion seems to be that technological advancement of civilizations depends on the age of the civilization. I realize that this point doesn’t invalidate the math in this, but I feel like it does play a part in how we envision older/younger civilizations and it certainly would affect our ability to detect them. It’s possible that some intelligent species develop on planets that don’t have the resources (fossil fuels) to become an industrial civilization or to develop the technology to destroy themselves. We could be surrounded by low-tech/no-tech civilizations that are similar to pre-industrial human civilizations but are much, much older than us. This is one of my preferred solutions to the Fermi paradox. We seem to assume that fossil fuels are abundant in the galaxy, but their availability depends on certain conditions occurring and the timing of those events being just right.

I feel Chaos theory is the missing link for the Theory of everything, funny how you look deep into chaos theory and you start to notice that randomness and all the chaos seems with enough time to become fluid and logical. Would love to see a video with those thoughts. keep up the good work!

They're everywhere. Thousands, possibly millions of advanced species in our galaxy, and most are probably at least somewhat aware of us, if they're not already visiting.

I have a next door neighbour that is an elderly spinster and she reminds me of early alien civilisations. Greetings from Italy.

I believe they would rather leave us be until we "grow up" some more.

It is such a wild and surreal thing to think about something as simple and plausible as intelligent life on another planet. Like all we are and ever have been, the things that define who and what we are as a civilization exist here on a tiny rock in but a few short moments on cosmic scale and to think that somewhere there is another one, or hundreds or thousands of civilizations that have their own unique history, their own wars, discoveries triumphs and downfalls is insane to think about.

Imagine we find a nearby civilization which is hundreds of years behind us.. Imagine all the horrors we would put them through just in the name of "studying or creating relations "

There’s nothing better than seeing a new Cool Worlds video being released.

Love the editing of this one! Thanks for the inspiring content you give us so often. Your channel is one of my favorites.

Good video analysis, thank you. This analysis assumes none of the civilizations would be interacting each other. As soon as this happens then what could be the results of that for the younger civilizations? Would they live longer due to higher technological help? I assume civilizations not interacting each other they are as good as consider themselves alone in the universe, which then in kind voids the interest of the initial question ‘are we alone in the universe?’.

Even if a race of aliens are so advanced that we seem boring to them, there will still be some alien nerds watching us because they still must publish or perish. So the results of their research may be published in small papers with low circulation numbers.

Wow! Where have you been all my KZfaq life lol?! Only found your channel today and so glad I did! All the videos are beautifully presented and very clearly and easily explained so a big thanks from me 😊😊

There's a lot of data here to support cyclicle societies here on earth. Very interesting!

I think one thing you may have left out that would bias the distribution even further to the red / older civilizations is that at a certain point, a civilization would become so technologically advanced (and possibly dispersed) that it would become very survivable. In other words, if a civilization can persist for long enough, then it is almost guaranteed to persist 100s of times longer still. So maybe something more resembling a lopsided U-shaped curve.

When people say that more advanced civilizations would have no interest in us, I don't think that is a factor of the age of state of technological advancement. I think the biggest factor would be their familiarity with other forms of life in the universe not originating on their own planet. Just for example, I think we'll continue to be fascinated for a long time by every new iteration of life that we discover in the universe, whether it be microscopic life or a civilization. I think that until we get to the point of understanding the nature of life, every new opportunity to study lifeforms that formed in different conditions will be of the utmost interest. I think that if we discovered a truly isolated stone age tribe on earth, I think we would be fascinated by it, although I would hope we would observe it from a distance so as not to interfere.

“ORGANIC CIVILISATIONS RISE, EVOLVE, ADVANCE AND AT THE APEX OF THEIR GLORY, THEY ARE EXTINGUISHED.” - Sovereign

I love how you go into detail regarding the question of distribution. One objection though: I would hope that technological progress will over long enough times decrease the frequency of extinction level events that can’t be dealt with. If that is correct, then neither animal species nor civilizations we‘ve seen so far are good models. We’re not even a type I civ yet.

The graph might change a lot if you take into account that a civilization's lifespan will likely get close to infinity if they are able to make use of Artificial Superintelligence for its own benefit.

I have just discovered this KZfaq page. The probabilities for that were great to begin with due to my interest in astrophysics. Still, I love it and will watch all the videos when I can. Thank you for this.

The mind-blowing thing about all this is that while it's most likey that humanity is somewhere in the middle there's also the chance that we're the outlier and are the very young or very old civilization.

I just subscribed to the channel - you make astronomy really palatable for curious minds! Thank you and keep up the good work!

It’s incredibly rare for complex life to have the right components to even allow it to exist that I honestly wouldn’t be shocked if we truly are alone in the universe

My thought is this, most civilizations must be on a similar level to us, some more or less advanced. But none the less looking or just now thinking about who else is out there.

You are my favourite narrator Professor Kipping. What a wonderful calming voice you have.

Can we just take a moment and appreciate how he can put amazing background music. I love your voice your channel all the way from Ethiopia.

That question always has me picturing different scenarios that would play out if we arrived at our new home world and found it inhabited by a hunter gatherer species. Would we be like the humans out of Avatar or would we be like Star Trek and leave them to develop without interference?

As you've mentioned yourself, I've always perceived that we must live in a rather young universe. This contributes to my overall hypothesis that while an entire WAVE of intelligent species came before us, they were the first(and only a handful of those species are still around, because time is like that...), and we are the very first of a whole NEW wave of I-life. E.T.s would have ample reason, then, to observe closely, but attempt to avoid too much interference: if you don't muck around in the experiment, you get pure science to learn from. I really don't think it's even arrogant or human-centric, etc. that I consider us to be a pretty damn interesting species. Look at the things we do. Doesn't matter the subject or situation, just have an objective look at humans. We're entertaining, at the barest.

Always so inspiring, so intriguing and so mind expanding! Civilizations and their longevity. When I hear David narrating I literally can feel my brain activating and thinking. Now concerning the ages of civilizations, extraterrestrial civilizations, I think that we project our human experience a bit too much on those extraterrestrial civilizations. Who says that they actually reside in civilizations? Perhaps they have a completely different take on that. Plus, concerning technological developments, perhaps they just don't need technology or use technology to thrive and expand. Anyway, I always enjoy listening to David indescribable much. Thank you!

Love your calming vibe as you present mind boggling themes and concepts.

Thing is, I clicked on my first Cool Worlds video thinking I'd found something sort of more like 'haha look at this cool planet it's so weird' and instead I found existential crisis after existential crisis.... And I love it.

Wouldn’t longer lived civilizations also find ways to survive like deflecting asteroids, harnessing fusion, space travel, etc?

I rarely watch videos over 10 min on KZfaq, except for this channel! Amazing content!

"If a civilization has a short lifetime, then it will leave behind less evidence of it's existence." Solution to the Fermi Paradox right there.

The memories or echos we seem to carry with us throughout our life cycles. Our soul memories and our generational memories as well. The visionary dreams we've had and or Visions in General. Our insights, our compassion, our big hearts, our natural blondness, our views about the world herself and our interactions with others are pretty friendly as well. Just wanted to share with you, that I've traced my family lineage back to 9000 bc and possibly older than that, but I've been super drawn to Lumeria and Atlantis and seem to know a hell of a lot about those ancient civilizations. I've known more that I have thought and the stuff I've found in Edgar Cayce's work and with 3 seperate sources that I spend a ton of time reviewing, we have cognitive abilities that only the more advanced races have. We may be blocked and have to unlock certain keys to gain more power and abilities, but I think I have most of the story figured out. It's pretty mind blowing. And free feeling when you understand the hell we've been through and have survived through We used to live hundreds of years, and remember our existences. These elites have set up a memory wiping type of veil upon soul integration into the developing fetus. But doesn't always work. In some pre ancient texts, there were mentions of how certain rulers would live for hundreds of years, sometimes thousands of years, because they were being reborn through reincarnation and could pick up where they left off, the spiritual and soul memories, that's how certain races/beings became so advanced, they were being able to evolve their spirits, minds, and DNA with each lifetime they would spend as a physical being. But something happened when the invasive races came from Sirius B and the Alpha Centauri constellations. The reptiloids and the drakinoids that began their destructivness after realizing how advanced our races on earth had been. We were capable of projecting our consciousness into other things and be able to animate those things, or objects or what have you. It was the same way with Crystal technology, like, the master teachers could upload their teachings onto crystals that they would pass over to their adepts(students) where the adepts could download the information via etherical energies and they were basically called 'Source-ers' not sorcerers, there's a difference in how this energy is interacted with, which are my next deep dives... I am going to start searching for clues on 'how to' do these things, the information about this stuff is readily available to study, but, the techniques on 'how to' do it, is still a mystery. I'm sure there's lots of 'how to' data on the deep web. But I'm not about to delve into that. I've traced our lineage back as far as 9000bc, before I lost the trail, but, it could possibly be much older than that. The Lumerian and Atlantean civilizations were 10500bc when things hit the fan. If I am correct I believe it goes back to the original clans, such as: Hyperborea, Tartaria, Thule, Crystal City, etc. We seem to know a shit load about the old world and like the astronaut Walley Shira and Pirate Shira, who sailed up and down the Western Shores of the Pacific Ocean, the explorer, Daniel Boone, the old time king of rock and roll, Elvis, Ruler of Scotland, Bloody Mary, former President, Abraham Lincoln, and former President, John F. Kennedy. Lots of Royalty and Leadership heritages. Both Abe, and Jfk were going to change things for the better, if not been assassinated, the world would probably be a much nicer place... Jfk wanted to expose things and their agendas, then pow! Gunshots ring out and they end up dying, but both men lived for a short few days after taking a bullet. Apparently, if you ever get a job with either government, military or provinces, it is illegal to talk about anything found under the waters in the hot zone, which is the Gulf of Mexico, you know why the ocean is always gone after major hurricanes? Its because Atlantis is rising. I found a new channel on youtube that covers a lot of Atlantis and Edgar Cayce' works in all his psychic readings, visions from Atlantis and Lumeria, and Egypt. He talks of these 'things' that are also called Automatons. Or basically, the scientists that were working with the genetics splicing and mixing with animals and other species, they were creating abominations or monstrosities which were like clones and cyborgish creations. The Belial and Luciferian races seen the original Atlanteans abilities, and technical advancements, seeing them project their conscious into their own avatars or 'things', Edgar Cayce called them things, which is really weird, cuz i call them 'things' alot as well. But im no Edgar Cayce... lol. He actually remembered all his past lives and who he was in each one, what gender he was and remembered his role in Atlantis, he was a high priest and if we take data points from the CDT-Plates, and compare them to Edgars readings, the story begins to fall into place way more. And he left a message behind before he died in the 1930's that humans need to reconnect to the spiritual evolutionary process and because, if we dont, our world timeline will become completely controlled by the Ai and the Elites. The stuff that's going on right now dudes and dudettes??? Well, for starters, Nueralink, by Elon Musk, just kicked off and is being rolled out since last week. I know, scary. Arizona is getting some weird happenings as well, like, it is now illegal to record the police here, that is completely encroaching upon our rights. Although it is still an open carry state. The state of Arizona has conix containers at the gaps in the border and refuse to remove them, but i think its more of a way to try and trap us in to not being able to escape whatever is to come. I am not a 'doom and gloomer' any more or less than the next person, but I have been paying a little bit more attention to things like I used to in the previous moments of my life.....

A couple of things - yes, I would leave the primitive society alone. At least, up till now, our interaction with less developed societies has not gone well for them. Perhaps, as we grow and mature, we might be able to find ways to be beneficial to a less advanced species, but I've always liked Roddenberry's prime directive. Also, on the other hand, you mentioned species who are much more technologically advanced than we might not be interested in us - but, considering a sample size of one :) us, maybe they'd still be curious, as well as perhaps find value in living representatives of a point in their past, now long forgotten.

I am not a physics students but I develop some real appreciation of statistics by watching your videos

Ever since I stumbled across a copy of "Cosmos" on my parents bookshelf when I was a kid, Carl Sagan has been one of the most inspiring modern thinkers!

Should there be an effect based on the rising lethality of technology over time? Weapons - stones, swords, guns, planes, missiles, nuclear, AI. In the beginning, the same species comes back but later a single mistake wipes them out instantly? Would that trim the tail?

One of the coolest channels I've seen in quite a while, I love the format of your videos.

That interstellar music should be used every time in your videos. It makes it sound so epic and interesting!!

I just love and appreciate your videos so much. They are always so well done! Thank you

That clip of Picard from the next generation brought back the nostalgia. Made me tear up. What an incredible show

It's pretty obvious that if there are any other technological civilisations, they are almost certainly massively ahead of us. Humans have only existed for a relative blip of time and and we've only been advanced enough to conceive of other technological societies for an even shorter blip. Odds are, any civilisation that is already extent, will have been for a very long time in our terms, even if it's a very short period of time in cosmic terms. In cosmic terms, any civilisation that got going before us will, by the odds, have got going countless millions or even billions of years ahead of us. The odds of another life-bearing planet happening to produce a technological civilisation within a few hundred thousands years of our own, is incredibly improbable. But a gap of even 10,000 years, which is just completely off the scale for improbability, implies the potential for massive technological deltas. On the other hand, you can make a pretty decent argument that there's a good chance there's no other intelligent life in our galaxy and possibly the universe. We know it took a few billion years for life to evolve from its origins to conscious intelligence on earth. Should it turn out that process happened a little more quickly here than the odds generally dictate, then factor in the need for a generation or two of stars before complex chemistry is possible, you quickly arrive at the realisation that it's very possible that we might well have got there first. This is obviously by no means certain. If, on the other hand, intelligent life took longer than the 'norm' to emerge on Earth, then you would arrive at the opposite conclusion - that we're late to the party. Personally, I think the huge lag on Earth between simple and complex life is a fairly strong indication that it takes a very long time for intelligent life to emerge and that the most likely scenario is that we rank somewhere among the earlier emerging civilisations.
