The Drake equation should really be a probability function of time equation because there are probabilities associated with most of the parameters and the inevitable Extinction given enough time with many Astro physics Extinction phenomena possible to characterize as a function of time
I disagree Simon finding out we are not alone is very important and a stunning breakthrough and yes it would have a spotlight in our news cycle for a while. But just like rocket launches of the past that were mainstream news and covered by every news outlet they have faded from our public consciousness. Elon Musk’s reusable rockets were astonishing but now they are passing news. The first few weeks or months of news of the new intelligence in our galaxy would be huge news, then someone would start a Tic Toc trend of peeling potatoes with a cement trowel or snorting tide pods through a straw, and a terrorist attack later and we would slowly move on as a civilization. Yes the science community would be very concerned and a new generation of scientists would work diligently on it but the fickle public would lose interest.
Part of the problem with hearing or seeing signs of intelligent life is they may be gone by the time we respond. As an example, Sagittarius A is 25,640 light years away from us. A lot can happen in 51,280+ years.
One day we are going to find out that simon is actually being held in a studio/prison cell; forced at gunpoint to narrate the scripts for all these different channels that his captors profit off.
You should consider making an episode on the semiconductor value chain. Perhaps the most mega of all projects ever done. Certainly the most advanced and expensive.
Very timely topic as well given the CHIPS act. I know we can't expect the whole endeavor to start churning out chips overnight, but what exactly **IS** the timeline for when we can expect results?
My gosh you do these videos well. I always learn new information from you on topics that I have followed for years. I am grateful for your work. My best to you.
We should study patterns we simply haven't thought of; using large data sets and dynamical systems theory. We're obviously missing a lot of things but there is plenty we don't know that we don't know.
From being the brunt of jokes & one of the most fringe areas in science to having dozens, soon hundreds, of telescopes across the world dedicated to search for extra terrestrial life. Yes, we have Drake & Hawking to thank for this most recent investment in SETI... but how many astronomers, astrophysicists, astrobiologists & other planetary scientists were inspired by Carl Sagan? His dedication & enthusiasm, from books like Contact to his work on Voyager, was contagious. All 3 are sorely missed but their legacies will live on.
I feel that there’s one thing about SETI which doesn’t get said often enough, which is a shame because it’s a good answer to detractors of the idea. It is this: We aren’t really looking for alien signals. That is impossible, because we do not know what such signals look like, having no examples of them. Rather, we are looking for things which have no natural explanation; and when we find such things, we science the hell out of them to figure out what could cause it which is NOT aliens. In this way, we make all kinds of new and interesting discoveries, and advance our knowledge of the natural universe. Even if we somehow knew in advance that we would NEVER find aliens, that kind of exploration is still worth something, because it helps us identify that which we have yet to fully understand.
Forgot to say, the background looks better since the blue light the shines on the bricks was toned-down. After watching this my kids want to watch ET again. Another great watch, thanks.....

Regarding listening for alien radio signals, what about the inverse square path loss? Over a path length of many light years the loss would be so enormous that any alien radio signal would be well below the noise floor.
@@beeemm5707With focused radio beams using parabolic dishes the inverse square law still applies dear chap. Focused radio beams using dish antennas improves the effective radiated power of the transmitter and the sensitivity of the receiver but the inverse square law still applies.
I got to visit the Green Bank Telescope as part of a school trip. It was pretty crazy. Wifi isn't allowed within I'm pretty sure its like 10 miles, because it will make it so the telescope just can't see anything. There was like one room in the facility that had internet and that was in a faraday cage, even though it was all ethernet. Its also the largest mobile structure in the world iirc.
I think about this all the time. Back in the 70s while I was in school I would often look out the window and wonder if we're alone and where does the Universe end.
I remember in the 90s, SETI setup a screen saver one could download and your own computer would check parts of signals downloaded for anything suspicious. I recently tried to find that screen saver to try and find Xenomorphs, but it’s now called BOINC.
I believe there's intelligent life out there, possibly because the idea of there NOT being something else out there in that infinity is more terrifying. I may be a solitary person and choose to be alone on this small planet, but for some reason, I don't want to be alone in the universe.
i like megaproject videos that are not focused on the war machine, but rather the better, more engaging endeavors of humanity. please more of these and less of those ;)
Glad to hear scientists are trying to think of different ways extraterrestrials might be broadcasting. It's honestly a bit dumb to assume beings lightyears away have developed technology even remotely similar to our own.
When you're talking about lasers, doesn't that all require it to be pointed directly at us or being very poorly aimed or it something on its way? Presumably interstellar dust and such wouldn't scatter that much. What am I missing?
One of the problems of looking for lasers is that they tend to be very directed. Sure, there is attenuation, and even if it was aimed at a receiver, some would leak around the edges, but we'd still need to be in a very precise location to even detect a laser. And there is no reason to believe any alien civilization would be intentionally aiming at us. Even if they were doing what we are, looking for other life out there, they may have tried to communicate with us hundreds or thousands of years ago, got no response, and moved on to other targets. There are a lot of factors that need to be just right for us to find any signal, but especially so for lasers. We need to be sensitive enough to detect it, at the right time to detect it, and at the right place to detect it. I'm definitely not saying we shouldn't be trying, but I'm also not going to hold my breath. Near future searches for those industrial byproducts is probably a much better option.
Our own emissions can only be detected from 100-150 light years away from Earth, because radar emissions only travel at the speed of light, which is pedestrian like in the grand scheme of things. If there is any extra-terrestrial life listening, they'd have to be within 100-150 light years of us to detect our emissions. Also, our transmitting and listening is also assuming that aliens are transmitting and listening specifically to radio emissions like we do too. We could be trying to listen to transmissions that we can't detect because we're too technologically primitive.
Another SETI project that is being worked on is PANOSETI. Which is an optical system with 48 telescopes that is currently being developed and already have a few prototypes operational in the field with hopes to build two observatories at Lick Observatory this coming spring. The team is also working with VERITAS. The ultimate goal of the project is all sky all the time. So we can look for very rapid light pulses, covering the entire sky, all the time.
Has there been another movie made about a telescope? Plenty of movies have telescopes in them but off hand I can't think of another movie that's actually about the telescope.
@@EllieMaes-Grandad Arecibo, it was only a bit part for the dish though. The Parks Radio Telescope has it's own movie, it's called "The Dish". Worth watching if you haven't seen it. Just to brag (something I don't get to do very often) a few years ago I was lucky enough to see a screening of The Dish under the stars at the dish.
Basically the simplest answer to the Drake equation is that nothing can travel faster than light. The equations show there should be many planets with intelligent life, but we can’t see them. Meaning they can’t travel here quick enough for it to be worth it, the light and signals from Earth won’t reach them anytime soon for them to detect. The older galaxies that could have intelligent life are extremely far from Earth, even the closest galaxies like Wolf-Lundmark-Melotte galaxy is the 30th closest in the universe to us. It’s 3,064,500 light years away. The first discernible signals from earth were between 80-125 years ago depending on how strong the signal would have to be. Meaning they won’t even potentially hear from us for another 3,064, 300 years if you round up. It’s just an enormous (just the observable part) universe especially it physics doesn’t allow for light speed travel.
What about our own galaxy which has 400bn stars in a 50,000 light yr radius? There could be hundreds of goldilocks planets within 100 light years of us. There may even be one orbiting Alpha C which is only 4.2 ly away.
It is too bad that they couldn't have somehow incorporated a listening device of some sort on our new Webb Telescope that will be visiting more stars and galaxies than Drake ever guessed were out there.
Yeah, a species hits the jackpot, technology sprouts, they create a huge mess and their planet shits itself, they go extinct. Bummer, man, but maybe that's how it goes.
I study philosophy in the university, and I can say that "the first contact" wouldn't be fundamental shift for ethics or philosophy over all. It would be major event, but not at all fundamental one. That what it would mean for analytical ethical studies would be just more work to be done. For normative ethics the impact would be modest one, utilitarian and deontological ethics (major paradigmas in normative ethical studies) are not constructed so that you can adapt those only to humans and humanity. Because the point is not the "content" of theories, but logical, phenomenological and metaphysical structures behind that content. Many philosophical thought-experiments already use as an theorethical method hyptheses about twin earths and other civilizations, so though this is theorethical guessing it has already taken into account the logical outcome that it is highly unlikely that humanity could be the only civilization and the only moral agents in this existence.
I hate to tell you guys this, but if you are trying to build radio telescopes here in SA you'd better build the power supply system as well because we certainly don't have the capacity to power them. Oh, and don't let anyone in the government get involved, or it'll cost you millions and never get built.
My first reaction to reading your title: "Only multi-million? What is this, a center for ants? How can we be expected to teach children to learn how to read... if they can't even fit inside the building?"
"If you're fond of googling mind blowing speculative space stuff, while probably stoned" bahahahaha! Guilty as charged! Now where did i put my potato chips??
The fact is that the immense distances between galaxies makes this near impossible. The Milky Way is 100,000 light-years in diameter so a radio wave would take 100,000 years to get here from the other side. It's never going to be possible to communicate with other beings unless they're extremely close to us.
Never say never. Only 150 years ago we thought it impossible to fly. If we survive long enough, we will invent currently inconceivable methods of communication and travel.
The idea not crazy ? Advanced alien civilizations would be using radio waves, technology that would give out signals. Maybe one day humanity will pick up a signal but i still think alien civilizations wouldn't openly contacted humanity because of competition. Good chance they would watch humanity.
If we’re looking for messages being sent through the hydrogen line frequency and also not broadcasting on it in order to eliminate some interference, who’s to say an alien race isn’t doing the same thing? Both looking for something that neither is producing. 😆
something that arthur c clarke pointed out in his book "imperial earth",is that any attempts by SETI are usually looking in the wrong place....because they are looking at the part of the spectrum they can see with those arrays,and any signal would be a very long wave indeed....just from the red shift alone. they would need an array several AU in diameter to see the length of the waves from any possible targets. this lets out any visible light targets. theres always a chance,but that chance would be pretty small.
@@MrTexasDan a red shift is also known as the doppler effect....the farther something is away from us,the longer the wavelength in the electromagnetic spectrum gets...it "shifts" towards the red end of the spectrum. get far enough away,those wavelengths get so long,you need a very long antenna to hear them....like i said,an antenna several AUs long. this is no different than the sound of a car driving away from you shifts downwards in tone as it moves away...except now you are talking light years away... any wave in the visible light section of the spectrum would be in the ultra low frequencies of the infrared.
@@markwelker95 HI Mark. Redshift counts for intergalactic distances, but inside our MilkyWay galaxy, things are not flying apart. We are all traveling happily together orbiting the center of the galaxy on a nice gentle trip to ... devastating destructive collision with the Andromeda galaxy in 5 billion years. Until then, it's all good. Redshift's not a thing at this scale.
@@MrTexasDan red shift is more than intergalactic....as an example,currently our farthest away spacecraft we have ever launched would be voyager 1....it was launched 45 years ago,and is currently about 81 AUs away....about 22 light hours...not even a light day,nevermind a light year....and the deep space array talking to it has to account for a red shift in the signal....at least 6 months out of the year,while we head around the sun farther away from it...they also have to account for a blue shift the other 6 months.... and it just made it to what they consider interstellar space. even the closest star to us is 4 light years away....and im sure that you would have to account for a red shift if you wanted to talk to any aliens there.
@@markwelker95 Sure, there are minor red and blue shifts in any local system. Even the velocity of the Earth around the sun would be considered minor and periodic. Voyager is red shifted because we propelled it away from us. But your original post spoke of taking into account redshift, which implies cosmological redshift ... the result of the big bang. Far away objects move away from us. In this case "far away" is even greater than intergalactic for even the Local Group of galaxies are gravitationally bound.
08:55 - Oh why did you discredit us for having filthy piano keys Simon? You're British 🇬🇧 too mate! That stereotype has long since be debunked! We actually have better teeth than most Americans! 😂😂
Thing is...... one of two things is true. There is no "superior" faster than light comms method, if so there is almost 0% chance to find a signal. Any signal would be "lost" in all the background radio. There is at least one "superior" faster than light comms method, if so there is 0% chance to find a signal. We don't have the tech. As such, any money spent on this would be better spent on finding new comms methods or "looking" for artificial physical objects. There's also the "prime directive" type of thing, until we reach a certain level of tech why bother with us.
If you wear a dark shirt on camera you should try and wear a dark lining in your jacket, especially with how well and how frequently you communicate with body language and gesticulation
I have lately begun to think about future long distance communication being done by pared paricles or some such quantum thing. And then I doubt we can hear anything from that. But looking at other tell tales seems really doable still. Then yet again, looking at the TINY timescale we have been around comparing with a planets life bearing time, do not give me much hope of seeing anything soon. Or perhaps at all during our lifetime. Ai do get smarter and faster all the time, so perhaps they will find something and recognise what that telltale is, and then tell us. Perhaps it simply is another ai that also has been tasked with the same job, that is left with its thankless job running since who knows when. Not that we could talk, I doubt anything is close enough for that. Unless there are something like quantum strings or something one could tap into and use.
Assuming convergent evolution processes will exist in other life systems, as it does/has across our systems/history, things gravitate towards a physical equiliblium; such as predator/prey and long period physical adaptions. This, under steady-state or very slow changes in environmental conditions, provides little or no opportunity to develop 'human' levels of brain and consequent environmental manipulation. For humans to develop (or exist at all) has required numerous mass extinctions of the dominant species AND numerous lesser threatening changes (ice-ages etc) that forced us to evolve different abilities and strategies. If these 'incentives/opportunities' don't happen often enough the dominant species maintains a physical status-quo, if they happen too often there isn't time for ours (or similar) characteristics to develop in a species. How does that fit into the Drake equation?.
in the universe, sure. but beyond our galaxy (or at most our local group) is too far to detect. the question is whether life is common enough to be detectable in our own galaxy.
This is great stuff! I really hope we hear something that proves the existence of extra terrestrial life in my lifetime. I can just imagine how that knowledge would terrify the world though.
anytime i hear the mention of 'the great filter' i am reminded of something else i watched a while back. not sure if it was you simon or one of the other historical youtubers i follow but someone once described humanity as 'humanity is a species with amnesia'. that we barely understand our past from 2000 years ago, let alone 200,000yrs. it makes me think that if such a great filter exists, perhaps humanity has hit that filter and faltered a few times.
The difficult part is keeping an open mind as to what intelligent life is. Because we only have one example (us) there is, naturally, a bias towards looking for something in our own image. Okay we have to start somewhere. Because of this I suspect intelligent alien life is as likely to be found by accident as by design.
@@mikesomerset6338 This channel isn't one to get facts from. It's entertaining, but it gets its info from easy to find sources, and their fact checking isn't much. And Simon's researchers don't know much about actual science. No, they aren't going to get technology we don't have that lets them violate the laws of the universe that we do know about. The only non physical things that anyone is sending into space is electromagnetic radiation.

3:20-3:25 called me out that's why im usually here lmao
I like how he's just got a black globe.
I study philosophy in the university, and I can say that "the first contact" wouldn't be fundamental shift for ethics or philosophy over all. It would be major event, but not at all fundamental one.
That what it would mean for analytical ethical studies would be just more work to be done. For normative ethics the impact would be modest one, utilitarian and deontological ethics (major paradigmas in normative ethical studies) are not constructed so that you can adapt those only to humans and humanity. Because the point is not the "content" of theories, but logical, phenomenological and metaphysical structures behind that content.
Many philosophical thought-experiments already use as an theorethical method hyptheses about twin earths and other civilizations, so though this is theorethical guessing it has already taken into account the logical outcome that it is highly unlikely that humanity could be the only civilization and the only moral agents in this existence.
Hey factboy, please do a video on bagger 288
Nobody will speak to us. If I was an alien, I wouldn't.
Yet you are still here
I hate to tell you guys this, but if you are trying to build radio telescopes here in SA you'd better build the power supply system as well because we certainly don't have the capacity to power them. Oh, and don't let anyone in the government get involved, or it'll cost you millions and never get built.
Maybe the aliens are ignoring and avoiding contacting us.
They're assumed to be intelligent life, so they know what they're doing . . . !
My first reaction to reading your title: "Only multi-million? What is this, a center for ants? How can we be expected to teach children to learn how to read... if they can't even fit inside the building?"
3:19 I feel called out.
whats the background music, calm piano, atmospheric, while he's talking about drake equation in first half
I'm not stoned, but I feel the Drake equation would be a lot more fun to contemplate if I was!
"If you're fond of googling mind blowing speculative space stuff, while probably stoned" bahahahaha! Guilty as charged! Now where did i put my potato chips??
Coughs, Simon, how did you know?
If you do hear something from out there, it most probably be hundreds of thousands of years old.
Hottake: we'll never find another intelligent species. The solution to the Fermi Paradox is that the Great Filter is intelligence.
I have decided people name projects based on the Acronym they want instead of something logical.
The fact is that the immense distances between galaxies makes this near impossible. The Milky Way is 100,000 light-years in diameter so a radio wave would take 100,000 years to get here from the other side. It's never going to be possible to communicate with other beings unless they're extremely close to us.
Never say never. Only 150 years ago we thought it impossible to fly. If we survive long enough, we will invent currently inconceivable methods of communication and travel.
The idea not crazy ? Advanced alien civilizations would be using radio waves, technology that would give out signals. Maybe one day humanity will pick up a signal but i still think alien civilizations wouldn't openly contacted humanity because of competition. Good chance they would watch humanity.
@12:43 Did we lose France or something?
Go to Essex they own the pubs
Hello Simon
If we’re looking for messages being sent through the hydrogen line frequency and also not broadcasting on it in order to eliminate some interference, who’s to say an alien race isn’t doing the same thing? Both looking for something that neither is producing. 😆
something that arthur c clarke pointed out in his book "imperial earth",is that any attempts by SETI are usually looking in the wrong place....because they are looking at the part of the spectrum they can see with those arrays,and any signal would be a very long wave indeed....just from the red shift alone.
they would need an array several AU in diameter to see the length of the waves from any possible targets.
this lets out any visible light targets. theres always a chance,but that chance would be pretty small.
They're looking in our galaxy. What redshift?
@@MrTexasDan a red shift is also known as the doppler effect....the farther something is away from us,the longer the wavelength in the electromagnetic spectrum gets...it "shifts" towards the red end of the spectrum.
get far enough away,those wavelengths get so long,you need a very long antenna to hear them....like i said,an antenna several AUs long.
this is no different than the sound of a car driving away from you shifts downwards in tone as it moves away...except now you are talking light years away...
any wave in the visible light section of the spectrum would be in the ultra low frequencies of the infrared.
@@markwelker95 HI Mark. Redshift counts for intergalactic distances, but inside our MilkyWay galaxy, things are not flying apart. We are all traveling happily together orbiting the center of the galaxy on a nice gentle trip to ... devastating destructive collision with the Andromeda galaxy in 5 billion years. Until then, it's all good. Redshift's not a thing at this scale.
@@MrTexasDan red shift is more than intergalactic....as an example,currently our farthest away spacecraft we have ever launched would be voyager 1....it was launched 45 years ago,and is currently about 81 AUs away....about 22 light hours...not even a light day,nevermind a light year....and the deep space array talking to it has to account for a red shift in the signal....at least 6 months out of the year,while we head around the sun farther away from it...they also have to account for a blue shift the other 6 months....
and it just made it to what they consider interstellar space.
even the closest star to us is 4 light years away....and im sure that you would have to account for a red shift if you wanted to talk to any aliens there.
@@markwelker95 Sure, there are minor red and blue shifts in any local system. Even the velocity of the Earth around the sun would be considered minor and periodic. Voyager is red shifted because we propelled it away from us.
But your original post spoke of taking into account redshift, which implies cosmological redshift ... the result of the big bang. Far away objects move away from us. In this case "far away" is even greater than intergalactic for even the Local Group of galaxies are gravitationally bound.
Was that an FLCL reference?
Some things we’ll never know? There’s things about our own planet we’ll never know
08:55 - Oh why did you discredit us for having filthy piano keys Simon?
You're British 🇬🇧 too mate!
That stereotype has long since be debunked! We actually have better teeth than most Americans! 😂😂
Thing is...... one of two things is true.
There is no "superior" faster than light comms method, if so there is almost 0% chance to find a signal. Any signal would be "lost" in all the background radio.
There is at least one "superior" faster than light comms method, if so there is 0% chance to find a signal. We don't have the tech.
As such, any money spent on this would be better spent on finding new comms methods or "looking" for artificial physical objects.
There's also the "prime directive" type of thing, until we reach a certain level of tech why bother with us.
The hydrogen line is so likely to be broadcasted on that we are not at all? What if the universe was quit only because everyone is only listening?
If you wear a dark shirt on camera you should try and wear a dark lining in your jacket, especially with how well and how frequently you communicate with body language and gesticulation
I have lately begun to think about future long distance communication being done by pared paricles or some such quantum thing. And then I doubt we can hear anything from that. But looking at other tell tales seems really doable still.
Then yet again, looking at the TINY timescale we have been around comparing with a planets life bearing time, do not give me much hope of seeing anything soon. Or perhaps at all during our lifetime. Ai do get smarter and faster all the time, so perhaps they will find something and recognise what that telltale is, and then tell us. Perhaps it simply is another ai that also has been tasked with the same job, that is left with its thankless job running since who knows when. Not that we could talk, I doubt anything is close enough for that. Unless there are something like quantum strings or something one could tap into and use.
Assuming convergent evolution processes will exist in other life systems, as it does/has across our systems/history, things gravitate towards a physical equiliblium; such as predator/prey and long period physical adaptions. This, under steady-state or very slow changes in environmental conditions, provides little or no opportunity to develop 'human' levels of brain and consequent environmental manipulation. For humans to develop (or exist at all) has required numerous mass extinctions of the dominant species AND numerous lesser threatening changes (ice-ages etc) that forced us to evolve different abilities and strategies. If these 'incentives/opportunities' don't happen often enough the dominant species maintains a physical status-quo, if they happen too often there isn't time for ours (or similar) characteristics to develop in a species. How does that fit into the Drake equation?.
I refuse to believe that humanity is the only intelligent life in the universe. It's too big, there are too many rolls of the dice for that.
in the universe, sure. but beyond our galaxy (or at most our local group) is too far to detect. the question is whether life is common enough to be detectable in our own galaxy.
This is great stuff! I really hope we hear something that proves the existence of extra terrestrial life in my lifetime. I can just imagine how that knowledge would terrify the world though.
anytime i hear the mention of 'the great filter' i am reminded of something else i watched a while back. not sure if it was you simon or one of the other historical youtubers i follow but someone once described humanity as 'humanity is a species with amnesia'. that we barely understand our past from 2000 years ago, let alone 200,000yrs. it makes me think that if such a great filter exists, perhaps humanity has hit that filter and faltered a few times.
I wonder if Simon knows that he made an anime reference at 4:26
No one says Fooly Cooley by accident 😂 FLCL forever lol. Homie’s personal life is probably more lit than his 15 channels
@@willc3900 He doesnt watch anime though, is where I was going with it, Im assuming the script writer included that
Well done Simon but please leave the red nick reference to us in the USA.
Can you do something on the importance of the Huffman Tree in determining if a signal is noise or a message?
Damn. How did Simon know I’m always stoned when watching space vids…
Whatever happened to SETI and the computing time that I donated to that project? What did Jodi Foster do with it?
The difficult part is keeping an open mind as to what intelligent life is. Because we only have one example (us) there is, naturally, a bias towards looking for something in our own image. Okay we have to start somewhere. Because of this I suspect intelligent alien life is as likely to be found by accident as by design.
No open mind needed.
We're trying to detect them from a distance. That means they'll have to send electromagnetic signals into space.
@@lordgarion514 the video pointed out that aliens could be using a technology we haven't got to yet.
@@mikesomerset6338
This channel isn't one to get facts from.
It's entertaining, but it gets its info from easy to find sources, and their fact checking isn't much.
And Simon's researchers don't know much about actual science.
No, they aren't going to get technology we don't have that lets them violate the laws of the universe that we do know about.
The only non physical things that anyone is sending into space is electromagnetic radiation.
