    Have we answers to what the Proximal Centuri "Wow" is ?That area has my vote aswell.

    We will make contact with our future selves, when we figure out this whole time travel thing. And definitely killing baby Hitler.

    If we ever make contact with travelers from another world, they most likely will live in all 3. They will easily commute from our local group across the galaxy in a flash and bound across the vast expanse of the universe at will. Traversing ♾@>>C means they won’t be from around here. Yet you say how is this possible? We are all made from two simple constituents.1. We are composed from the 10x“^80” atoms in the universe 2. We are also a spark generated from before time. This is all. We will never be more than the combination of these two simple constituents. We, nor anyone else will ever be able to traverse the vast expanse of the universe lugging around heavy atoms, nor can we or anyone else generate the power needed to compress and stretch space so that a starship can blast around in our 4 dimensional physical realm with such zeal. But I can imagine the spark that we are all made from can easily run, jump, and play amongst the galaxies once it learns how. And once you learn how, you have little need nor want, to participate in the journey of a being who has yet to find that treasure itself. If we meet them, it will be because they made a grave error in judgment. Bravo for the question David, the remarkable existence we find ourselves in, is fascinating to ponder.https://youtu.be/A8LRxIANzQs

    What a great attitude, I think I got adversity + grit = perseverance; Independence + collaboration = progress. At some point though, perseverance + progress should = ETOH, with a spritz?

    I say A if we are including any forms of life. There has to be a high chance of bacteria and microorganisms on Mars or Venus. Amd how do we prove these aren't "intelligent" if we do find them. If we are talking about intelligence life capable of space travel, my answer is intergalactic getting to the next galaxy would mean they already had contact with us if they had thay capability to travel between galaxies...

    Logic would dictate to hear from somewhere closer to us simply because of the time it would take to make contact. But then again I'm bad at science.

    One request: Please have a look at the article linked here. https://thenextweb.com/neural/2021/01/15/scientists-figured-out-how-to-turn-black-holes-into-power-sources/I'd absolutely love to see you explain the concepts behind this. Ever since Hawking proposed his theory of Blackholes having hair, I've dreamt of planet sized space ships being powered by the enormous energies of controlled black holes.

    I vote A, because I think if it's a 50/50 proposition that either we are alone vs. a plethora of sentient aliens, if we do see evidence of extraterrestrial civilizations, it will be close. Otherwise, nothing will be available to detect.

    So happy I found your channel. Your content is exceptional, and it's nice to find a channel that stays away from all the noise going on in the world. Anyway, you've expanded my mind and I really appreciate the effort you put in to this. Peace.

    We would likely contact a civilisation from within our own galaxy. This is because if there are others out there then every galaxy should have intelligent life if our galaxy has another civilisation. I can never wrap my head around the fact we may be alone even though I understand the Abiogenesis argument. It just feels wrong because of the shear possibilities we are presented with. If we are here then others must of been here to my mind. I also think we will find life in our own solar system deep in the oceans below the Ice.

    Hello there I am not an undergraduate or or senior graduate ,in an just an enthusiast on space,time ,universe etc.I recently came across a video from the 1st lander/rover that went to mars and they did a 'life test which came up as positive (nutrients in water and the water bubbles to show microbial life ) ..NASA dismissed this but never dis an other test like it since or even on the new rover that's on its way there. Given there are seasonal plumes of methane on Mars would it be foolish to say that there is microbial life on Mars ?And could be go further and say there has been a 2nd genesis? Or has meteorites shared the same genepool?...which I suppose comes.down to wether they are left or right strung on the DNA.strand.In short...isntjere life on mars and WHY is NASA not denying it ..

  • RainbowConnection manota

    David I would like to make a request. If possible could you do a video on the subject of Dark Matter and Dark Energy. I know that you-tube videos abound on this subject matter but your talent for presenting scientific information in an understandable format is extremely good. The current theory on this is that these items are place holders for things we can-not fully explain or understand. I am just sorry I came across your channel a little bit late and hit the subscribe button.

    Good luck with the new channel. If we ever make contact with a non-Earth civilizations, I have faith that the source will come from (B). We should have already made contact, if they were (A) (ignore the pyramids) and the signals will be too weak for civilizations from (C) to be the first contact. In fact, we are well into the range where they may have detected our faint electromagnetic radiations (radio, etc) and have sent a reply that is in transit. If I were as bold and smart as Elon Musk, I might state that we will, almost certainly, receive alien civilization contact by 2050 or so - if the simulation allows. :-)

    Extragalactic would be cool, but due to the vast distances I think it's most likely to happen intragalactically.

  • Brixy Brixhamite

    There is always option - d) messages sent from another universe (specifically a neighbouring membrane universe). If that was to be detected I can only think of one way such a message can be encoded - embedded in a gravity wave signal (theoretically gravity waves may be the only way to send a signal between universes, but the advantage might be that the signal could come from very nearby.Theoretical physicist Nima Arkani-Hamed seems to support the possibility that gravity may be able to pass between universes this way;https://www.scientificamerican.com/article/watch-live-today-quantum-mechanics-and-the-fabric-of-our-universe/LIGO is good for detecting very powerful events at a distance, but for detecting gravity waves from another universe we might need something closer to a gravity wave microscope (rather than a gravity wave telescope). The reason for this is if the object is from a neighbouring membrane universe then the distance between might be comparatively small.If gravity can pass between membranes then perhaps there may even be intelligent beings on a neighbouring planet Earth who embed a signal in gravity waves.

    B.The reasons are:1. The time scale involved in traveling between planets at relativistic speeds is so great even with nearby solar systems. It takes so much of one's lifetime, or requires sleeper ships, so it seems likely that few would find the will or need to attempt it (not to mention potential time dilation). Thus,2. It would require superluminal speeds to make it worthwhile. But assuming that our neighbors had already mastered that technology, I suspect that,3. They would have already visited because we would be a logical first step for them. And, since, they haven't,4. It seems likely that any aliens who have developed superluminal travel capability would be somewhere outside of our general neighborhood and simply haven't gotten around to us yet. But,5. If they were from outside of our galaxy, it seems likely that they would still be exploring their own galaxy for many centuries before they explored ours. And thus, playing the odds, I think intragalactic aliens with superluminal drive make the most sense for our first visitors.

    In response, I think intergalactic. Our local galactic neighborhood would surely have produced some signals or signs that we could detect. Extra galactic. Wow, the distances are just too mind blowing to comprehend. Any species capable of traveling such distances would be so far advanced, I just could not see them bothering with us. Such a species communicating with us, would be like us trying to have a conversation with a fish about the positives and negatives of the internet. Such an advanced species might find us quaint to study, but would probably feel the same level of remorse over our extinction as we feel over the extinction of the Dodo. Unfortunate, but shit happens... Oh, by the way, we've got a cool looking stuffed Human in our museum. Look at its weird hair and freaky primitive eyes. Move along now.

    If a means within a hundred light-yearsthen I say we have barely had enough time to look at a very small percentage of anything close to us and that's only the stuff we know of

    We will find intelligent life in other parallel realities, but we will have some issues with common reference points, and hence we will assume that they are only anomalies.I think it makes sense to let them find us, much cheaper. What could go wrong?

    You are doing an extraordinary advertising for science and critical thinking. As the president for the Association humaniste du Québec and secretary of Humanist Canada, I want to thank you. I am a retired engineer (electronic physics) and your videos are illuminating my older years. I was always convinced one day we would visit the end of the Galaxy. I thought it would take 1 million years (back of the envelope). But thanks to you, it may very well take much, much less. I think you are the Constantin Tsiolkovski of our time.
