Drake Equation: What does it mean if there is alien life and the hotline blings
That can only mean one thing!
Some similar video ruclips.net/video/ZK0CB2Bk_QA/видео.html
You ever go exploring the city or town you live in and inexplicably discover some part of it you've never been to before or even heard of? These parts of towns or cities are always tucked away somewhere dark and gritty and there's usually not many stores or neighborhoods around them. That's how I've always thought of the Milky Way galaxy. It's really the only way I could justify to myself why we haven't been discovered by intelligent life or why we, ourselves, haven't discovered intelligent life. We live in a part of the universe that is like a hidden neighborhood. Maybe we're too far away or getting here from wherever "they" are is too difficult or strenuous.
Of course, I've also heard the notion that intelligent extra terrestrial lifeforms find us to unevolved to bother with. I mean, Jane Goodall went to study chimps and their habits. She didn't go there to involve them in world politics or technology.
So why can we not detect them then?
You're confused on n-sub-e. It's the number of planets _per system_ that might be habitable. Not the total number of planets in the galaxy that might be habitable. And the vast majority of exoplanets discovered so far have been jovian planets, not terrestrial planets, so even the 3400 figure is wrong.
It’s very likely that the number of exoplanets that have been discovered is just a small percentage of the actual number. Conditions have to line up perfectly for us to detect the planets. So far that’s limited the systems to ones with very close orbits. It would be very difficult to discover an earth like planet with an orbit at 1 au with a similar orbital period. For large stars the habitable zone might be 10+ au away.
3400 is probably undercounting significantly.
Maybe aliens just don't feel like going to space, have you thought about that? I know I never visit my neighbours.
That would fall under f_c
Or maybe we are the first intelligent life form in the universe, i doubt that though.

External sciences always lead to the exploitation of the environment and its inhabitants for natural resources the animalistic process of life will occur throughout the cosmos in the material world advancivilizations or more involved in returning to God's head spiritual nature that transcends the material modes of nature from which nature is born from
Wow huge fan.had no idea this was one of your vids. Named my gamertag after the Drake equation I follow your podcast on Spotify. Keep it up my guy.

These are deep lines dude!
Nah lol too much words just put it simple
We are very social animals we live for interaction
Josh! You are a national treasure
No, "exoplanets" are just planets that are found beyond our solar system. They don't have to be capable of supporting life. You should have said, "exoplanets that are in the habitable zone".
yea I caught that as well.
The equation needs a new variable which sets the % chance that such intelligent being would WANT us to receive communications from them, assuming they have the technology to NOT send them our way.
Hello! I'm writing a thing about the drake equation for an assignment, and I was wondering if I could use your explanation of what N = R* x Fp x Ne x Fl x Fi x Fc x L means? I won't use it word for word, I'm just wondering if I could use the words that were on the board behind you when you explained it, while also using some words you said in it. I'm wondering if it's okay, I'll also credit you. It's okay if not :)
The potential life supporting planets could actually be much greater because we're assuming other life forms couldn't evolve unless they had similar conditions to our Earth, but we now know of species that can survive in environments we never though possible, such the Tardigrades which can survive extreme heat and cold, radiation etc, even in space ( also known as water bears, many people have now heard of them since they're becoming popular in science fiction shows and south park etc), there's also life forms surviving in extreme environments such as in super hot and acidic volcanic waters. www.bbc.com/future/story/20170803-in-earths-hottest-place-life-has-been-found-in-pure-acid
ben both equations don't even mention moons , there are more moons than planets , many of these moons are planet sized objects these also could support life , could you imagine a super earth with 2 large moons all supporting life,what an amazing system that would be ).So bearing in mind there's got to be billions more moons than planets ,that's got to bring the chance's of finding life even more favorable odds .
Came here for drake equation that I heard from Big Bang Theory TV Show 😂
😂 sheldons non stop explaining
Came here from TikTok from a comment made about the Drake equation
& it brought me here today from the same episode.
Came here from a NASA article
I came here from lex fridman podcast!
I do have a question, if we do send a radio wave or probe with radio signal how long would it take for it to reach the planet that has most likely developed life forms and if they do encounter it and are able to answer back how long would it take for their message to get back to us?
How many earth life spans will it take for the total time of us getting a message out there and them answering?
well.. radio waves travel at the speed of light. Let’s say there’s alien life on a planet in another galaxy. Andromeda is 2 million light years away. If we sent a signal today, it would take 2 million years for it to reach them. If they respond, it would be another 2 million years until we got the signal back. So that’s 4 million years total. To put that into perspective, modern humans have only been around for about 200,000-300,000 years. In my opinion, there is most certainly other life out in the universe. Purely based on probable statistics. (Look up the Drake Equation) But the reason we likely have not found life is simply because the distance between us and them is incredibly far. There’s a chance we may never find life. Our own sun could expire and humanity could die off completely before we ever received any sort of contact. Or… it could happen tomorrow. But for that to happen, a highly advanced civilization would have to send a signal to us long long ago. In which case, they might even be extinct by now. The universe is huge.

Even if there are definitive numbers to get a result, the question is still unanswered of where.
Thought of a pretty interesting question and solution to it recently. Is the pound a unit of force or mass?
I think it is a unit of force as pounds per square inch is a unit of pressure, which is force / area
'pound' is a measure of weight, so the force produced by a mass in a particular gravitational field.
It's actually a unit of currency,
Professing to be wise, they make themselves fools.
I never wanted know what Josh Clark looked like. But I clicked on a random video and here I am regretting everything.
Such this cool subject deserves much more rock and roll type of science delivery
It’s just crazy that any one single factor of the equation , when tends to zero , (except Ne) , the chances of life on that particular planet is an absolute zero…..great explanation !!!
Getting people to think is always a plus ♥
ok, quick question, why did people dislike this? whats wrong with this video? i found it educating even though i know and can explain drakes equation myself... why would you dislike knowledge?
Woah, this channel is still around? Cool.
Yep! We're just uploading less frequently 'cause we're all working on new projects.
*QUESTION, PLEASE* There's a high school named after Enrico Fermi in Enfield, Connecticut. Does he have a connection to the CT area or were they just tired of using president's names? : )
adam mac Why don't you google the school and find out ?
Aseril.. Simple answer? I'm lazy. : )
Extraterrestrial civilizations are using entanglement communication so that's why they can't hear them out there. They have to figure out why entanglement works first.
drakes equation hugely underestimated the difficulty for life to exist. the formation of primitive cells and lifeforms and dna is actually extremely extremely complicated and difficult combinations of chemicals and transformations even in the scale of universe, which the formula fails to take into consideration of these, its not just a simple vast number thats suitable for life existence, not to mention how rough it is. a lot of people would think thats possible but in reality it isnt, which is why seti running for so long is a complete fail.
"We should have been visited" is the most overstated lack of thought process.
Life evolves to serve itself at the minimum to protect itself. Our milky way and solar system is made to protect us.
And why would life want to visit our planet unless it was trying to harm us?
Intelligent life on Earth didn't start until the day beer was invented.
I am pretty sure Drake knows nothing about his own equation
Ilnik2047 Yes definitely he can’t solve it, but at least he think of an equation that will soon in the future will having results.

I thought the Drake equation was how he makes songs.
Lolll
In science the origin of life is a complete mystery. There is a big difference from a planet or moon being able to sustain life and support biological evolution than any environment producing life that has arose from non-living matter.
It begs the question for one to give a percent of the chance of life being anywhere else when we have no idea what caused life to be here on Earth. What was the percent of chance or odds that Earth would produce life? How can anyone answer this question without knowledge of how life arises at all from non-living matter?
This is the obvious and glaringly flaw of the "Drake Equation". It presupposes some form of "Abiogenesis" as true without any evidence at all. It presupposes life's origin was due to a particular cause and specific environmental conditions without one shred of evidence of support.
I believe your n sub e number is incorrect. It is not the total number of exoplanets, but the number of planets PER star that could have life.
The Drake equation is an incomplete equation. I have a theory worked out that uses the Drake equation but also factors in Cr. C sub r. Chances of our own rediscovery. In my thesis o explain why our chances of rediscovery is much more likely to happen then other extraterrestrial communications.
speaking of, we explore space but know almost nothing about life on this planet... agreed it improves daily, but we are far from being smart in regards of knowing ourselves... point being, we aim nuclear devices at each other...

We are not alone my friends, we're just not ready for whats out there. We do have tools like DMT(thats all around us in nature) that provide small windows inside other realms of our universe. It's truly amazing what out there.
Something I always consider when thinking of any Theoretical issue. If I was to take everything I know and added it to everything that every other Human has ever known from the dawn of time, I would still only have 1/billionth of one percent of the available information...I can not surmise a conclusion on anything with that limited amount of information. =/ As far as ET's go, If someone can Prove they do not exist, we can then prove they do, because its Us.. ;)
This guy cracks me up from the 1st second :D Props
Josh you are the best!
First time I heard about this was when Howard tried to calculate whether he has a chance of finding a girl
Dan Moran same
Dan Moran big bang theory?
vishal Sharma yup
First time I learned about it was today in school
How can an extraterrestrial signal be detected; with the right medium or frequency or decoding?
The Drake Equation needs an update. It’s too dependent on radio wave technology. By doing so it is omitting any civilization that may have skipped right over radio. Radio is an extremely poor method of communicating across interstellar space. Time lag makes any meaningful communication impossible.
Also that variable will continue to change as our technology changes. To narrow our search for extraterrestrial intelligence on whether they can use human types of technologies is being too anthropocentric.
I was thinking, should there also be a part of the equation that factors in the chance of a mass extinction event or events on the host planet that could wipe out any life that has developed? The earth has had many such occurrences and has come close to total extinction of life a few times. Asteroid impacts, volcanism, climate change just being a number of possible causes.

This is a great beginners guide to why the astro sciences are important and interesting. Those who are taken with it and want to go further, try Ward and Brownlee "The Lucky Planet", which takes Drake's Equation and adds all the latest findings from astronomy, astrophysics, astrobiology, astro chemistry, genetics, archaeology and history. The main reason why, despite the thousands of planets found, that we're still alone, is that while the ingredients for life are plentiful, the conditions needed for first, single cellular life, then the huge jump to multicellular life, then the next huge jump to multicellular intelligent life, involves variables that are extremely rare in the universe. Stability over extremely long time periods, very quiet areas of galaxies, particular planetary arrangements and orbits and tilts, very specific planetary types and positioning in their systems, but mainly, a special type of moon at the exactly right distance, of exactly the right size and mass, and in exactly the right orbit.
When you add all the new factors into the Drake Equation, you'll understand why we are alone in this galaxy, and probably the universe.
The Drake equation is the one that estimates the odds of making contact with extraterrestrials by calculating the product of an increasingly restrictive series of fractional values such as those stars with planets, and those planets likely to develop life? N equals R times FP times NE times FL times FI times FC times L?
It cant be Zero because we are here man.
لعميق
The saying that seems to be repeated is if there are intelligent life forms out there then they would have visited us by now. But we are a pretty advanced species, yet we do not live off planet or traverse the solar system or universe. So who is to say there aren't other planets out there with life forms that are on the same or lower level of progression as we are. Conscience yet not zipping around the galaxy yet.
6 upside down its a 9 now
Sharjil 9 god?
LMAO
Hey man
The n_e term is the average number of planets that might support live per star with planets. Stars do not have 3,400 planets on average. en.wikipedia.org/wiki/Drake_equation#Average_number_of_planets_that_might_support_life_per_star_that_has_planets,_ne
drake the typa guy to …wrong drake my bad
hey what did you use to edit this video
How could an intellectual of the magnitude of Fermi come up with such an illogical conclusion as, "we should have been visited by extraterrestrials many times by now." He made some baseless assumptions about a) the age of the universe; b) the number of planets that could exist and sustain life; c) the ability to travel through space; and d) the willingess to do so.
"If you take all these things for granted - which, it kinda makes sense to" is BS. How can you assume any of that?
Every factor in the Drake Equation is fudged. At least he admits that they're all a bunch of random guesses - but then he says, "the logic behind it is all pretty sound." No it's not - not if it's based on illogical assumptions.
The Fermi Paradox & the Drake Equation are really not even worth considering.
Great explanation but please correct your mistake. The ne should be the average number of planets capable of supporting life per star system, not in the entire galaxy.
...........and the average number of moons too
I can't understand f sub i, how to describe that a civilisation is intelligent or not. What are the parameters
Also, on top of that, can anyone explain why exactly why it is the rate of new star formation (R*) is included in the equation, It makes enough sense that I can logically see it needs to be included in the equation but unlike the other parameters I can't actually explain why it is so necessary. Searches online have amounted to nothing unfortunately so would appreciate if someone is able to explain it clearly:)
Very well presented. :)
Maybe also consider those whose Intensification of intelligence offers them creative leave in the form of living on moons, asteroids, planets w/unusual atmosphere and many other possible such as man- created planets and systems of life so far above our physical vision as to 'not be seen' and not considered. Food for thought
Great explanation !! I reckon this should be one of the first equations that kids ae taught around 8 or 10 (if not already) as it brings a great insight into probability maths, science and speculation at the same time opening doors to bigger questions and understanding where else equations can be applied to existence on the smallest or largest scale :)
I learn more from This videos than School.
"If you take all these things for granted, which it kinda makes sense to, we should have been visited by this intelligent life time and time and time again by now. And yet we only have anything approaching definitive evidence that we're alone in the universe."
Adult in the room points out hundreds of years of fairly consistent UFO sightings around the world.
"Noooo!! That doesn't count!! Oh no no!! That's pseudoscience!! Just NOOOOOOOO!!"
Adult in the room realizes that's why we're not ready to meet the aliens.
Thank you
you do a nice job
How come there are different versions on the internet
هيلو صحاب العميق😅😅
The first commercial wireless telegraph started in the 1890s. At this rate, longevity (L) will be about 200 years. So long, humans. It's been fun.
We did the Drake Equation and came up with a number of < 1 for number of planets in the Milky Way which would have intelligent life. Sounds like Earth is quite lucky.
But since we are part of the Milky Way then your calculation must be flawed or we are not yet deemed as intelligent. Which one do you think is most probable?
@@kiwiowl we have achieved a status of intelligence in this galaxy where the chances are small. This is amazing!
Maybe all the cool Aliens are just hanging out at Drake's place and when we're advanced enough we can go there too...I think it's somewhere in the centre of the galaxy, my parents say I'm not old enough to go yet but I'm pretty sure that's where everyone's headed
i like your video and way of explaing stuff
Thank you SO much
Ohhh.. I thought it was
lonely guy + lonely girl = Hotline Bling
The equation includes intelliget life outside our galaxy but we can not interact with a civilization whose signals we can not detect within our galaxy. So N is how many civilizations in the universe could send information we could detect here in the Milky Way.
Wow, this got deep.
maybe drake is an alien
No he is my nigga
Down the street
Liked his honesty, "....random guesses and wild speculation...." Zero times a gazillion, is still zero. Wishful thinking X What if X a guess here X fill-in the blank here X whatever = Life. Sounds to me like the Ancient Aliens TV series. The big bang is another nice one, boom.....all of a sudden, something from nothing. Let me know when it's discovered how to construct a single cell organism, starting only from elementary elements (stardust).
why always we are finding life just like ourselves..they may be somewhat of another kind
When you see a planet that has life, the distance from earth to that planet would probably show that the planet that has life is already without life...
Really bad presentation. Not only uninformative, but poor fundamentals. Equates measurement with pure guesswork. Using 3400 turns the equation into an inequality. The data from Kepler gives f_p ~=1 as a good guess. Rather than focusing on scientific issues, he rambles on.
During the time this video played start to finish 2,107 Millennials snorted a condom.
As humans, we're incapable of the knowledge. Throw the speed of light into the mixture. Then consider the infinite size of the universe. It would be amazing if we could find a thing.
"The square root of sixty-nine is eight something, right? Cause I've been trying to work it out"
the fact that we exist means none of those terms are zero right? otherwise there would be a zero chance of us humans existing in the first place
I've been looking for hours on different videos' comments to see someone crap on the Drake equation because I can't be the only one who thinks it's totally useless and no more than what a child would write in their diary. First of all, if we knew the f sub i or f sub c, we could just throw the whole equation out the window because we already found what we were looking for at that point. For real everyone seems to think it's so cool but geez. Anyone else?
I'm here because I'm from Andromeda & I searching for any Intel fiction/non fiction on off planet mathematics. Just seeing what would pop up.This did.Let's see what I learn...or what relevance this has to my questions..
the Drake Equation is what says all intelligence annihilates itself before it can do anything...
The presenter is unaware of the INTRAVIA HYPOTHESIS which states simply that "Since we have not seen life created, we do not know all the conditions necessary for its occurrence." In addition to planetary conditions (atmosphere, temperature, water, etc), there may be one or more "cosmic" condition(s) necessary which may have existed for only a limited time in a limited space. (The level of background radiation from the Big Bang might such a "cosmic" condition) Thus, it becomes plausible that there was only one planet with the right conditions AT THE RIGHT MOMENT. Put another way, the Drake Equation may be missing a term ... of arbitrarily small value.
The next example: there are countless grains of sand on earth. Really a lot.
Now I take one of them and with a very small laser I print my name and address on it. In the color red. I only do this once.
According to science and probability, there should be at least, I'll name just one number, just like Drake did, at least 10,000 grains of sand with my name and address.
Can I have a Nobel Prize please?
great video on
Coming here from #storypedia
I m here after watching ad astra
The drake I know can't come up with this equation
I use drake equation to find out the chances of finding the one for me
So just to see if I get it... Josh is talking about Drake? hmm ok
The Drake equation is interesting, but the Fermi Paradox is way more interesting.
Drake equation is flawed. "Fl" (fraction of planets that develop life) Is a HUGE assumption- the probability of abiogenesis is on the order of 1/ 10 to 104th power. The entire UNIVERSE is calculated to be 14 billion years old. Not enough time for this to happen.
For example: The problem of formation supermassive black holes- they agree not enough time for conventional star formation and death to have many black holes to merge to the order of million black hole sizes (which is average for a supermassive black hole-some are billions in size). If a conventional physical process and the age of the universe do not allow supermassive black hole formation. Then how does a complex process like the simplest cell that can do protein synthesis, reproduce, or photosynthesis occur at random in the "short" time the universe has existed?
If the universe had infinite time for life to occur, I agree it could happen. But according to the current understanding, there is NOT enough time to life to arise by chance.
Let me make a statement, then ask a question. Life hasn't evolved once on earth. There have been millions or billions of species, or lives, on this planet. A perfect planet for life, since its proven to support all kinds of life, water, land and air species. But of All the species that have come and gone, just on Earth, only one, the HUMAN species, has been successful in developing the ability to meet the f factors in this equation.
Why are we not using our own planet to extrapolate out the probability of species to develop communications that could be heard through the universe?
You'd only need to look at the success rate on Earth. The probabilities are infinitesimal for it to be successful around the Universe. Although, with enough numbers, I'm sure it could be possible. Just wondering. 😁
