Finally! Michael Crichton made similar points some years ago (it would take a fiction writer with a scientific mind to sniff out BS so keenly). The compounding of UNKNOWN variables still make them unknown. That popular scientific personalities talk about the Drake equation and other similar notions with such bias has seriously dumbed down the scientific dialogue in our society. We also talk about modeling in other areas in the same way, as if these equations are not speculative but somehow predictive. Kudos to Dr. Kipping for treating science like a process, not a corruptible worldview.

- @@A_Stereotypical_Guy here is the definition of a scientist in its strictest sense: a person who is studying or has expert knowledge of one or more of the natural or physical sciences. "a research scientist" From this, we can surmise that a scientist need not have a PhD. A person can attain expert knowledge from independent research, without having gone to university and received a PhD. This would accurately describe Bill Nye, whom has devoted a massive portion of his adult life to the study of more than one field of science. He is respected by professors and the greater scientific community. So, a scientist he is, a qualified professor with a doctorate he is not.

- What he wrote in 2003: "More recently we have seen the rise of the so-called 'Rare Earth' theory which suggests that we may, in fact, be all alone. Again, there is no evidence either way." This is an ignorant person's skepticism. He doesn't know anything, so he doubts everything. Equally fallacious, he plays up correct theories that initially weren't accepted... until there was evidence, but he doesn't emphasize that requirement, as Sagan does at 21:30. So he scorns assertions of likelihood when there is evidence (he doesn't know of) and scorns the establishment for dismissing theories that he deems sufficiently backed by evidence when they aren't. I would be embarrassed to have written with such a tone of playground antagonism for that level of audience (see link), while also betraying an inconsistent standard of empirical support. Sure, Africa and South America "fit" together, but there also seems to be a face on Mars. Coincidences happen, so evidence needs to be accumulated--such as similar fossils below the time of continental separation and dissimilar species above. When you take pictures from a closer distance and different angles, the facial symmetry vanishes. This evidence takes time to amass. Extraordinary claims require extraordinary evidence. Or as Feynman tried to teach with his license plate explanation, you can't use the hint that gives you the initial hunch to test that very hunch. Unlikely things happen all the time, so you need to collect _new_ data to see if it supports the hunch. The ubiquity of rare events is why hypothesis testing seems very conservatively structured to the uninitiated. Feynman's UFO discussion with a "layman" distinguishes whether talk of knowns or talk of likelihoods is scientific. Sure, we don't _know_ that we're not being visited by space aliens, but that doesn't make us unscientific to take sides and say it's highly unlikely. We _can_ talk about likelihood, given what we already know. That is in fact allowed, when there's data. Bayesian reasoning _is_ consistent with the scientific method. Or as Feynman put it, from what he knows about the world around him, reports of UFOs have more to do with the known, irrational characteristics of terrestrial intelligence than with the unknown, rational characteristics of extraterrestrial intelligence. As Christopher Hitchens would point out, one of the rules of oratory is that arguments presented without evidence can just as easily be dismissed without evidence. But that's not what's going on in this case. 100B galaxies of 100B stars cooking for 14B years is what Kipping is taking on, as is the Miller-Urey experiment. Slowly evidence is amassing in the astronomical and biochemical fields on both the ease and difficulty of abiogenesis and convergent evolution of technology-wielding intelligence, and the time to cook up the heavier elements that assist life. The trouble is when people make assertions that "we just don't know" as an excuse to dismiss talk of likelihoods, use of Bayesian reasoning, and evidence that already exists. To do so is just indulging in a false equivalency. And it's especially annoying when it's born of their own ignorance of evidence that already exists (an agnosticism of laziness). stephenschneider.stanford.edu/Publications/PDF_Papers/Crichton2003.pdf

- While I agree with your statement, im of the firm belief that what we are "in" is a super-duper advanced holographic simulation (akin to Star Treks "holodeck", but obviously on a much more larger scale, and complexity). With that being said, it could very well be that all that space out there in the universe is a mere "illusion" and doesnt really exist [until/if such a time arises that we are able to physically reach it, then it could very well "pop" into existence, as in the phenomena of manifestation. The phenomena of manifestation is very real for me, insomuch that I witnessed it on at least 3 occasions during my lifetime. Some would say im a kook, while others think im merely misremembering things...and thats ok. I know in my heart the phenomena is real and exists. Lastly, yes it does make your mind do one huge "Whoa !!! WTF ?!?!?!"

- @@Aurochhunter Let's look at our own planet. How many species did we have since the beginning of life on this earth? Billions of life forms and only one was able to use tools, books and fire. So it must be VERY unusual to develop this kind of 'intelligence'. Another factor is the possibility to destroy the own environment or own species with the right tools and weapons. So intelligent life will probably have very short life cycles compared to simple forms (which also have way lower demands to their environment than complex forms of life)

- We're still finding new/undocumented species of life here on Earth. Just because we've not seen it, doesn't mean it does'nt exist, because we have plenty of examples proving that assumption wrong. It was once thought that life could not exist in extreme temperatures. Then we found a wide array if life forms thriving on deep sea hydrothermal vents, in temperatures ranging from 400f to 700f. We've also found life thriving in lakes underneath the Antarctic ice sheets.

- its basic stuff found in the first paragraphs of the first chapter of any decent analysis on the prospects of alien life; and a distraction from the correct best answer we currently have. Astronomers are good at pointing telescopes at stars and looking at spectrographs, but typically bad at logical analysis / reasoning on the prospects of alien civilization. The first law of reasoning for alien civilization is never trust an astronomer's analysis, they have all sorts of screwed up bias and archaic modes of thinking. Astronomers are among the last people to be consulted this on matter. Ok onto the elephant in the room, the biggest myth of our times, which the naive astronomer didn't address, and has never objectively thought about it in his life and never will: 1. The idea that alien civilization would blast out radio communication, loud and clear, hence our satellite dishes should be jammed with alien radio transmissions. This myth was created back in the early days of radio communication around the 1920s when most transmissions were sent uncoded. Thinkers at the time assumed radio comm would remain that way practically forever. Today most radio comm is encoded so that it resembles random noise; but it is digital as apposed to analogue, which distinguishes it from natural background noise. However it is easy to convert a digital radio stream into an analogue stream then add a few pseudo noise fx to make it completely indistinguishable from natural background noise, except for those with the encryption keys. This is how aliens communicate. 2. The myth that we can detect the tiniest signals from the other side of the universe. Actually, our best technology ( Nasa Deep Space Network ) can detect synthetic information from a synthetic source from about at maximum 180AU or one light-day away; it is 6 orders of magnitude smaller than the detection sensitivity we'd need to evesdrop info from the nearest star system. In case you haven't noticed, we can barely detect exo planets directly. If a whole exo planet can't generate enough waves to be detected by our best scopes, its going to be hard to detect an artificial source unless its pointed directly at us, and for us. This leads us onto 3. The idea of convenience that aliens want to communicate with us. In technology they are millions or billions of years ahead of us. It would be like us trying to comm with bacteria in the dirt. What is the purpose? Just to poke the bacteria and do experiments on it. Any discussion about alien civ should address these points. The astronomer's lecture was conspicuously lacking, like a half man lacking half his body and head.
  @plasmaastronaut Жыл бұрын
- 4. The myth that inter stellar aliens comm using spherical wave broadcasts, this one's again from the 1920s. For interstellar space it is more sensible to use rasers ( radio equivalent of laser ) to aim a coherent beam at a target star system. (a) less power useage, (b) much better stealth; no other star system would detect the signal. The chance that we'd sit between 2 alien star systems and be able to intercept their signals is extremely low, and in these cases, aliens can simply divert signals around the solar system. That we might postcept signals after they pass their target star can be stopped by alien engineering, they can adjust their rasers to difuse enough to be too weak to detect past the target star system and also the target star system can send out an neutralizing wave signal to reduce the signal beyound the receiver. Show me the astronomer lecture that mentions these points. protip: u can't because astronomers are dumb.

Great lecture. Dr. Kipping is completely correct. I personally want there to be a Star Trek like universe out there just waiting for us to discover it, but what we've currently observed shows no evidence of that. You can get into as many thought experiments using statistics as you want, but at the end of the day we just don't know. Those thought experiments are important, don't get me wrong, but they prove nothing. This might not be very exciting, but this time we live in is very important.

- @Wikileads No, not necessarily. As Professor Kipping said, we simply don't know, so the possibility that alien civilizations exist is as legitimate as the position that we're alone. But when scientists start proclaiming the galaxy is teeming with alien civilizations when there is zero proof of this, and insult people as arrogant or whatnot for not believing a position for which there is zero proof, then this is anti-scientific behaviour. Not the same as insanity but not appropriate either. I can understand what op meant by finally a sane response. Professor Kipping's analysis is a rare instance of evidence based logic and thoughtful even-handed balance amid a massive myriad of emotional reactions. The scientists who let their wishful thinking propel them to enthusiastically premature conclusion arejust one part of this.

You could still imagine what an external observer of the Universe would think if they found us in such a big Universe. They would still update their probability, based on that observation, and conclude that the probability that there's EXACTLY one civilization is much lower than there being at least a few.

And I don't know who created the creator, dear Mr. Richard Dawkins. but that's ok, we don't even know who created the pyramids and and how they did it. how would I know who created God?

This is exactly what my thinking is. If you have an Earthlike planet, with plenty of the ingredients for life. We simple have zero idea what the probability is for those ingredients to come together as needed for life to start. It could be common (although the SETI program could suggest otherwise) or it could be unimaginably rare. We have no idea! Assuming life is plentiful--especially intelligent life--is simply unfounded. And until we can create life in a lab and/or have a sufficiently large sample size of planets vs planets with life, we won't have any idea.

Hi. Very rational and level headed video. I'd suggest the emergence of multicellular life was billions of years earlier than 700 million years ago. It possibly got started many times, but was destroyed by meteoric bombardment, which was more common further back in time. It may be that m.c. life only gets a solid foothold after the solar system has mainly cleared itself of its interplanetary junk, until then it's "back to square one" (one cell) hundreds of times over the three billion years since life started. Meteoric impact has definitely had a significant part to play, because without the KT event we'd never have displaced the dinosaurs. Cheers, P.R.

- Rather,@@tonoornottono, I contend that it's not simply convenient and subjective consideration - based on ourselves. It's a product of the knowledge that *all* life requires energy. In fact all creative or constructive, or transformative processes we can conceive of, have an energy input of some sort. Where there would be a sentient intention to create something specific, it is reasonable to expect steeplingly requirement for energy.

- My english is not good, but I understand your statement and i wrote just about modern science. Why do some weird humans think the other planets must have inhabitans? Because of the fact of waste spaces without population? The mosts planets don't offer atmospheres for any creature. Wether animals nor any other creature would ever be able exist there and nowhere was found any clue of those possibilities of life. Since time immemorial mean humans this creatures can be find . Either this probably existing creatures are in a save hiding spot and they are laughing about this stupid humans or there just don't exist. How stupid that notion to ignore!? No science found ever creatures beyond earth. The bible says on, God owns all planets and nowhere says bible on about any hint of other creatures in the universe,...like every science says. Excavations don't bring also to light indications of any creature. Not even something about islam . Only about iron age and Jesus time was found. The temples Solomon etc. Satan is lying to us and many killers say in court they weren't forced by Satan to kill somebody. Catholics are not better, because they are lying too. Revelation warns about the pope as he is an antichrist. Jesus' day of birth is unknown and chrismas, eastern aren't mentioned on bible. No problem celebrate this, but that has nothing to do with bible or christians. Islam is also a lie, which Satan uses for distracting humans from Jesus. Other populations beyond the earth or another life before our life now are lies and distractions from Jesus. Exactly that says on the bible. Scientist aren't able to confirm any islamic prove, how Solomons temple residues for example or any other useful things during iron age. Pre-existence can't be proved also. No war was an idea of God, because only humans are blame! Allah doesn't help or he can't help his fans for having a better life. Those nations are ruled by poverty, wars. Otherwise there remains nowhere any Christian among poverty, no matter where he lives. Show me one Christian who lives in danger, in poverty, but I can show you a crazy not existing Allah, who can't change it better for his fans! To believe on other creatures is also a diversion created by Satan, like I mentioned detailed!

The main reason that no alien life is mentioned in the bible, is that the bible was entirely written by humans, starting back in the Iron Age. Human society back then didn't have the technology to investigate distant celestial objects and phenomena.

Wonderful lecture. Thank you, especially, for the green-ball-in-the-urn analogy.

But the green-ball analogy does a nice job of showing this bias for what it is.

Mind you, the increasing detection of exoplanets similar to Earth suggests that we may indeed be average, which is the whole point in this theory. I think he might have to go back on that one.

- @@duke_of_oz But this is not what we are discovering. In fact, out of around 1000 solar systems, we have not found a single star system that resembles our own. Most of them are dominated by gas giants as inner planets which make the formation of earthlike planets impossible. More and more, our solar system with rocky planets in the habitable zone, and the gas, giants, further out, appears to be a one off anomaly. The rare earth hypothesis appears to be more or less confirmed, and life, as we know it here on earth, or indeed, life at all, may be vanishing rare, and in fact unique to earth. This is what Professor Tipping means by the Copernican principle not being valid. Earth is not ordinary and the solar system is not ordinary.

- I'm the same. I can't imagine the probability of life evolving. From what? What created the spark? And, after the spark the evolution is so fast that mere mutations in DNA due to the suns radiation could not possibly have enough time to create the diversity we see. It's just soooooo amazing. Obviously, Darwin could see the evolution of life. But, the big jumps are not explained in my opinion. For example, the mission link.

Most everything here is spot on IMO except for one thing: The existence of extremophiles almost certainly increases the odds of life being elsewhere somewhat. It may be less likely for them to have evolved in extreme environments, but the likelihood that they can thrive there opens up the possibility of them being transported through space by natural forces. In which case, they only need to have evolved once in an ideal environment, and could have easily been deposited on may other worlds since that time. (transpermia) 100% agree though that scientists should be agnostic in the absence of more evidence. We know that transpermia might be a possible mechanism, but it is not known for sure if it could actually work that way. But with that said, if someone who had evidence and for sure knew the answer to "are we alone" were to point a gun at your head and ask for your best guess with the caveat that if you guess wrong, they would pull the trigger, what would your guess be? I know for sure mine would be "no. we are not alone" But if someone asks me if I believe in alien life, my answer is always "I don't know, but it is certainly possible"
