  • Could it be that aliens are trying to communicate with us right now, but we're just not listening in the right way? They might have chosen a specific frequency, time or method of communication that we just never thought to try. In game theory, two players can co-operate towards a common goal even without communication. The idea is called a Schelling point - today we'll explore what this is and how it affects our search for life in the Universe.

    I'll leave my hot take here. I fell in love with science through listening to Carl Sagan and his calm, inquisitive tone was something I fell asleep to on a lot of nights. I have nothing against Neil DeGrasse Tyson personally, but I think this channel is carrying on Sagan's mantel in a way I appreciate more. All of the videos feel so full of wonder and without judgement. Well done, and thank you.

      Tyson is a brilliant human being, but he’s too closed minded/opinionated on too many subjects for my full respect. On another note, think about the vastness of space, the stars, galaxies, etc. There’s no way it’s just there for us to observe and appreciate in this life. It’s impossible for all of it to be “just there”. There’s so much more waiting for us. Until then, take care and enjoy your time here, and I’ll see you on the other side fellow human 🤙🏻

      Exactly! And there's just no way that it ever was or will be FOR US. The moment we realize that the universe does not have us in mind or anything else in mind, because 'it' is not purposeful, is the moment we can free ourselves from such provinciality and truly enjoy the wondrousness of the cosmos for what it actually is -- "just there."

      Welcome to being a human. You can imagine how people over 1000 years ago felt. The same way we do now. Even with our "technology" we really haven't accomplished that much. No human have left our solar system, let alone our galaxy! I'd imagine that moment if it ever happens to be one of the truly first steps of mankind in our journey to attempt find alien life elsewhere. Maybe we're "lucky" and there are aliens close to us. Maybe we should start by taking care of our planet and each others before we attempt anything else. From an aliens perspective we must be quite a destructive species.

    Fantastic and mind-expanding work, once again. The knowledge and originality of thought you share are a huge gift to the collective. I have idly wondered if it might be possible to beat pulsar signals against each other looking for any interesting patterns (or "messages") in the beat waveform. Going further, perhaps one might try using a separate, offset pulsar (offset in both space and frequency) to provide a reference frequency and then heterodyne with however many pulsars to get some very weird semi-music from the sky.

    Hi Professor, can you do a video on the “veneer of water” problem? One thing I’ve noticed is that the worlds close to the sun have nearly no water at all, but worlds that do have water have way too much. If we had the amount of water relative to Europa, there would be no continents at all, or at least no dry land on the surface. Seems like there’s a “fine tuning” issue for life on earth where we had just the right amount of water. 50% more or less would be disastrous for the development of civilization on this planet.
    Edit: I haven't done the calculations, but I believe if we had something like 50% more water than we do, every single piece of every continent would be underwater. Even Everest would be under the waves. I think even 20% more water would bury most dry land under water. Likewise, if we had 50% less water, it would be difficult for the water cycle to continue and we'd end up with a runaway evaporation event where all the Earth's water would eventually evaporate into space, and life would be impossible. Performing a precise calculation of how much water is required so sustain life on Earth would be great. My hunch is that there's not a lot of margin for error, and we maybe have as little as 20 to as little of 10 percent of margin otherwise either life or civilization would be impossible.

    Interesting video, thanks for putting it out! IMO aliens might be very alien, including in the way they think, so our assumptions of what is meaningful to them might be just ourselves projecting.
    For the rationale on the video for example, initially I thought the first option would be to use means of communication like the internet or classifieds if this was before the internet. Without them, maybe find the exact geographic center of the US, then the exact center of the year and meet there on July 2nd at noon. Or at least go to the least populated town in the US on July 2nd at noon because that makes the most sense. Going into a highly populated area would be dumb and crazy... And then you mentioned New York in the video. Then you mentioned New Year's Eve... It goes to show that even among us we can think so differently as to have polar opposites in rationales. Chances are we will think very differently than aliens too.

    Really interesting concept, I accidentally think about this a lot but didn't know there was a word for it. The thing is I wonder how useful they really are. Stephen Wolfram had this interesting thought that physics itself may look totally different to beings that parse out the structure of reality - even just slightly differently. Their technology stack could be built on completely different things, and different laws of physics. Not just laws we haven't discovered, but ones we couldn't ever recognize from our vantage point in reality. But perhaps even if this is so, it just means we have to go a layer of abstraction deeper to find the appropriate Schelling points.

    I'm a smoothbrain, but just thinking like a caveman, I think a good place to start for Schelling Points in space would be when the largest planet in a given system crosses its inferior conjuction in relation to us. I imagine (just my imagination) these large planets are the most easily observed, and would be the easiest target to potentially hit for signals transmissions. After seeing this video, I speculate our best location for receiving contact from other systems would be around Jupiter. Very cool video!
    edit: this makes a lot of speculation and assumptions, I'm not a scientist or qualified to speak on the matter.

      Putting a radio transmitter around Jupiter is also a good idea because in a previous video we saw how can humans turn Jupiter into a giant satellite dish basically. Easy to transmit, and to receive data, and with jupiters inclination from the ecliptic plane, more systems would be able to detect Jupiter transits around the Sun.

    The existence of Schelling points depends on having the same or at least compatible intentions. So we need a civilization striving for contact with another one. In our own civilization there are at the moment only some groups actively searching for contact - most people are indifferent or even sceptical if it would do us any good. We could assume that in many civilizations at a similar cultural and technological stage there would be similar or even stronger reservations (depending on culture, history, psychology), while civilizations at a lower technological stage would not be able to communicate at all and civilizations at a higher (or radically different) cultural and scientific level would assume radically different Schelling points (if any).
    So it is the old problem of meeting someone with a similar state of mind at a specific time in their and our (cultural) evolution within a distance which allows some kind of communication using our existing technology - and radio waves e.g. became indecipherable noise at a certain distance. If you are very lucky and if you use highly sopisticated equipment, you can perhaps identify it as probably coming from an artificial source, but that is about all of information you can get from it - a lighthouse in space, but not one able to send at least some morse code.

    Are humans 1-sigma in that type of hierarchy? Are we "dumb" relatively based on the requirements? Are we somehow more intelligent than normal?

In terms of intelligence, I think a species would need to reach a point of where they become capable of passing complex knowledge between one another. This way they could sort of manifest this emergent superintelligence that we utilize today.

      @@nawtmyrealnamelol I agree, but communication is one of only 2 requirements for the type of runaway (exponential) technological growth that humanity has undergone. The other is the ability to create new tools from the environment, and requires not only intelligence but also creativity. Even if a species possesses human-level communication ability but is unable to figure out that, if you attach a stone to a stick, you combine the length of the stick and the power of a stone, then all of that information transfer and collective memory that ensues from this communication ability will be of no use.
      The reason that technological progress has been exponential since pretty much the dawn of civilisation is that, as newer tools got created, those newer tools were used to create even better tools, and those were in turn to create yet better tools, etc. Of course, knowledge about how to build the earlier tools would still need to be preserved for the newer tools to be built, so collective memory ─ pretty much only attainable via advanced communication ─ is still necessary, but its role can be compared to that of a catalyst; the actual "reactant" in the phenomenon of technological growth has been our ability to create tools.
      So, it seems like the answer to OC's question is probably the same as the answer to the question of what baseline level of intelligence one would require in order to be able to create new tools from the environment ─ a question that could hypothetically be scientifically answered via testing.

    I think one of the biggest problems were the interaction of two ideas you brought up: Technological Comparability and the Speed of Light
    In order to have a hope of communication, we likely need to have (somewhat) similar levels of technology. Humanity wouldn’t be able to communicate with a civilization more than a century less advanced then us, and we probably couldn’t receive communications from one a few centuries more advanced.
    Yet, if we are using shelling points of specific times and places (say, a gamma ray burst), then because EM Signals travel at lightspeed, it could take thousands of years before it arrives at a planet to receive it. If they were of similar technology when we sent it, they would almost certainly be either extinct by then or have evolved beyond the original modality of communication. And if they originally weren’t sophisticated enough but were once the signal arrived, they would have no idea about the shelling point and wouldn’t know where to look.
    The inability of species to communicate in real time (according to physics as we understand it) is perhaps the biggest obstacle towards actual communication

      @@CoolWorldsLab yes but I thought that we were aiming at speaking to a less or equally advanced civilization

      Mind explaining why communication wouldn't be possible with a civilisation more than a few centuries more advanced than us? Pretty sure a life-seeking civilisation would want to send a signal that all intelligent life-forms could understand ─ not just lifeforms at least as advanced as them, as that would narrow down their search range significantly ─ and so would probably send the most easily decipherable signals ─ ones that we could pick up on.

    Ok I just gotta say this... Bro... It is an absolute pleasure to have you make this content.... I love space.. Universe... And even just the concept of our reality and I've actually been watching you're videos for a while now... But I wish I could have just a sit down and convo about it but I DJ across the country and its like no one cares about our advancements... And more so just the thought of making contact with other species (out of this world).... What if we are the only ones here... But to me... As far as my perspective.... There's no way it's just this world that harbours life! Maybe different perspectives as we call it ... But yeah.... I think it is only a matter of time!

    The probability of finding some civilization around our own technology level, seems to me impossible, given we are just in our first steps as a technological advance civilization, everyone out there should be milenia ahead of us.

    I always imagined we were missing something "simple" to other civilizations; like the Star Trek subspace communication technologies.
    Strange but my sense of humor always imagined our first contact to be us creating a subspace transceiver only to illegally tap into the subspace network of our galaxy's version of the ferengi.
    Our first glimpse of advanced civilizations is a galactic shopping network.

    David Kipping is the only one who is the only PhD that is not afraid to say “we don’t know” for subject matter we don’t know. For that reason I’m willing to pay very close attention to every word, every sentence.
    Almost all the rest simply make stuff up so it’s always hard to determine where known facts end and educated speculation begins.

    I'm keep thinking about relativity. Could you even have an idea of where in time would be a good time to communicate? Doesnt relativity somehow come in the way of communicating in time?.. so to speak.. I'm not an scientist but I love science non the less. Your videos are inspiring so thank you.
