The Drake Equation After Sixty Years | Part 1 of 2

Ғылым және технология

Sixty years ago Frank Drake wrote down an equation that has become one of the most famous in astronomy - the Drake Equation. This formula, aiming to estimate the number of alien civilizations communicating within the galaxy, has been celebrated, abused and criticized. Today, we are taking a deep dive into this special equation in a two part special. Written and presented by Prof David Kipping. Thanks to Jason Wright and Nadia Drake for help with this video.

    It looks like a shopping list of things we would like to know. Problem is Scientists are like a person going to the shop with a shopping list whilst hungry. They start picking up the things the thought they wanted but keep finding ever more interesting things they didn’t realise they’d ever really needed 👍 that’s why science is awesome.

    This is one of my favorite stories. As a SSgt in the USAF, I was stationed in South Dakota. The very first troop that got right out of his training was a kid that had lived most of his life in Chicago, followed by Dallas. After he got to our station, I invited him to dinner at my house up in the Black Hills. After dinner, we were standing out on my porch, looking at the stars. I made the comment, "I bet you've never seen stars like that in the big city." His response, "Yeah. I've never seen so many stars. It's a shame it's cloudy though." It was a perfectly clearly night. I was dumbfounded. "What do you mean cloudy?" He responds, "That big wide cloud going across the sky." I realized what he was talking about. "No, bud, those aren't clouds, those are stars. That's the Milky Way." I've never seen someone have their entire universe expanded in such a short amount of time.

    I love channels like this, that blow my mind on a regular basis. When I was a kid, my Grandpa told me that no matter what I do, who I meet or what new things I may try, always try to learn something from it. Be it a person, a place or activity. Learn from it. Even if it doesn't seem to teach something at the time, you will realize later on, that those experiences may help when you least expect it. Because of his influence, I've always made it a point to learn something new every day. Granted, that is much easier these days, thanks to the internet and channels like this. It always amazes me, that despite how much humans learn, it pales in comparison to what isn't known, and may NEVER be known. Or as Grandpa would say through is ultra thick, weathered Scottish brogue: "You learn something new every day, and you still die an idiot." I miss Grandpa. Thanks for all the work that goes into these videos.

It also gives us a pathway to estimate the number of civilizations without directly observing one through statistical methods. It is conceivable that we could one day measure the value of each term with experimentation and measurement.

    I had the opportunity to go to a guest lecture at the U of A with Dr. Drake presenting his equation. Seeing him talk through it in person was surprisingly funny. He builds it up and up and then says at the end, that the answer is... "N". We don't know! That was ~20 years ago and the answer hasn't changed. It's a great thought experiment and the equation itself was well-crafted by a fun, interesting person.

    Prof. Kipping, Thanks for another great video. Your description of the Drake Equation (around 6:36) brought back some memories. A rate (of star formation), multiplied by a series of constants, multiplied by time: dimensional analysis, something I've not done for nearly forty years! But is that why Drake used the rate of star formation in the Milky Way in his equation, rather than the total number of stars. Around 18:37 you observe that the Drake Equation "... splits something we don't know into lots of things that we don't know." But isn't that how science works? You take a big problem, break it up into smaller problems, assign values to each one and combine the results to give an answer to the original problem.

    It is useful as a thought experiment. But it is based on multiple unknown (and currently unknowable) values to such a degree that, factually speaking, it is simply guesswork.

    absolutely amazing. I've always considered the drake equation (one of) humanities great inspirational conundrums. As often in science, previous generations leave unanswered questions for future generations. The drake equation, to me, is a thousand year, multi generational puzzle. Something to spark young minds into the fields of science. Big questions like Fermi's paradox, Drakes equation and Implications of, and moving up the Kardashev Scale, all inspirational goals for humanity to achieve. I believe when we can answer all of these within a reasonable error margin that we will have entered a new age of humanity and hopefully be able to solve most, if not all problems by that point in time. Between the great thinkers (like yourself, Sagan, Fermi & Hawking to name a few) and the people with the will (and the money), ie) Musk, love him or hate him, is inspiring people to find ways to do things previously thought impossible. Maybe one day we can fill in the blanks, But even if when we do, if the answer is a resounding 'no life except on Earth', I'll still hope that there is and we've just missed something as the alternative is just too depressing to know that we've almost screwed it. It's people like you and the community around here and channels like it that restore my faith in humanity in dark times. Thank you!

    I'm no genius but it's clear to me and rarely ever talked about in regards to the evolution of life on Earth. Our moon keeps the earth's poles from wobbling, providing long-term stability. Not only is the earth in the goldilocks zone but our moon is the perfect size at the perfect distance, that is something I don't think The Drake equation accounts for.

    One of the ways to explain the core controversy of the Drake Equation might be to look at it from the point of view of the great theorist of rhetoric, Kenneth Burke (whose work largely dates back to the same time period as the equation), and the notion of "terministic screens". Burke suggests that the way we read something (or for that matter, anything) is constrained and guided by terms and frameworks of knowledge these terms reside in. The two main types of terministic screens that Burke's work focuses on are: scientistic and dramatistic. Scientistic discourse, from Burke's perspective, is grounded in a purely (it as purely as possible) observational mindset - the goal of science being simply to provide a better and more precise description of the world as it is. The universe has a tendency to surprise us with phenomena that any language, any conceptual framework we may have, simply fails at this descriptive task - so, scientists constantly generate new terms, explanatory frameworks, and equations to simply keep up with this discovery. Science strives to make its language interpretable, sure, but the ultimate goal of scientific discourse is to do no more than describe. And if the universe proves itself strange, inexplicable, and irreconcilable with human notions of agency, intelligence, or free will - well, it's not science's job to provide comfort, only to achieve better precision within our limited means and with acknowledgement of the great deal of uncertainty that even our best instruments leave us with. Dramatistic discourse, which most of Burke's work had focused on, is the rhetoric of most of the commonplace world. It may exist in many of the same places as science, and use the same language spoken by the same people - but it differs from scientistic discourse in one fundamental way: where science aims only for description, the grand "drama" that humanity naturally sees itself starring in is always using language (and other communicative means) to determine motives - to give guidance on the "thou shalts" and "thou shalt nots" of the world. Human action, human agency, is only possible when we see ourselves moving through this great cosmic drama, armed with knowledge of what we must, should, can, or cannot do. In this quest, the terministic screen is woven from threads of familiar stories, which allow us to readily slip into the shoes of heroes and follow in their footsteps to take what we generally see as our rightful place center-stage. ...and it's the very nature of humanity to be profoundly frustrated when presented with something that portrays itself as wisdom, yet seems to wrongfully give no guidance on what to do. This, I think, gets at the heart of the issue. Drake and his equation, in the meeting with his colleagues at Green Bank, were placed squarely in the realm of science, behind a terministic screen of scientistic discourse - where their goal was no more than to try and create a better, more precise way of discussing extraterrestrial intelligence; to provide not a guide or a template for "how to do SETI", but merely generate better descriptions of the vast uncertainties of the very questions it poses - from which one could begin to look for observational data to fill in the blanks.The Drake Equation could be said to be a sort of miniature terministic screen - a blank screen, but one configured to accept and work with terms as observations arrive. It makes perfect sense for what it is. Unfortunately, the moment we leave that situation - even science as an institution is not free from human drama; after all, it's done by human scientists, and the funding comes from sources bound up in the arch-drama of politics. And so, the drama that is human society and human action demands reasons, seeks to extract motives and implications for itself and how to act - from something that was not designed to give those answers. And all the press releases simply fan the flames of our frustration with science that tells us of a universe far too big, far too strange, far too uncertain for our individual agency, our individual drama, to matter. Motives are thus invented and ascribed, and familiar mythos injected into a description to turn it into more of a story. And so, the Drake Equation only frustrates more: because it cannot at once make for good science AND good story, and so we end up taking one side or the other, growing only more frustrated with the other side's view. Thank you for inviting science back to the table here in a calm manner, and reminding that while there may not be a story IN the Drake Equation - there is a story ABOUT it that, when one calmly listens to it, can be profoundly satisfying, even without a clear solution forced upon it!

    It’s cool that we are at least finding lots of exoplanets now, none were discovered when Drake equation started. If we can find tons of exoplanets, we can figure out how many of them are in the Goldilocks zone, rocky, containing water, if they have a large moon, if they have a Jupiter like planet protecting it, if the planets star is in an older, mature galaxy. A big question is just how important all those factors really are. But even if all those situations are required, there’s just soooooo many stars it seems almost impossible that advanced life isn’t out there. I think many scientists are mostly talking about the Drake equation pertaining to our galaxy. I realize it’s huge with 400 billion stars. However even if theirs only one or two planets with advanced life in our galaxy, think about how much life exists in the universe! There are as many galaxies in the universe (with billions of stars in each one) than their are stars in our galaxy. That’s a lot of planets. Based on mathematics alone, it just seems impossible we are alone. I honestly think that even if we assume life can only evolve with a planet with all the things we understand as necessary (large moon, Jupiter planet nearby, liquid water, plate tectonics etc…. I think we’d still find plenty of life out there, based on the numbers. That’s of course just my guess. I also wouldn’t be surprised at all if life exists out there that requires totally different things than we do. One of the coolest things to think about is if life exists out there that we wouldn’t recognize as being life. I also have to wonder if the universe is still pretty young for having advanced life (at its peak)? Seems like the older the universe gets, the more “safe” it becomes to allow life to evolve. Even though the universe is 14 billion years old, it’s still a “baby” in comparison to how long it will last. Our milkyway galaxy happens to be a pretty old galaxy, maturing now for billions of years so it’s not super active like many galaxies.

    Once again, progress is obscured by the complications arising from it's presentation. When drama attaches to an idea, more attention is given to the drama, than the idea. Thus, to a degree, an idea can be diminished by maliciously causing drama.
