Humans have a long "ongoing" history of lies, stealing, violence/wars, military expansion and biochemical warfare. If there's any intelligent space aliens in the universe there's ZERO chance they would trust us. Logically since they know we can't be trusted it means we humans would be classified as a potential threat. This means the best case scenario would be those intelligent space aliens controlling and limiting our expansion in the universe.... and there's many darker more scary scenarios. Any intelligent space life would behave this way out of protecting it's own existence. Knowing the best case scenario means the intelligent space aliens would be limiting and controlling our expansion in the universe.... yet here we are providing them our exact location in the galaxy. It's like cooking cheese hamburgers and steaks in the African jungles for 5 minutes and wondering why no friendly animals have arrived.... Ohhhh they are coming and they won't be friendly.

We are actually getting much less radio noisy due to radio broadcasts becoming an outdated technology (yay the internet and cable TV) and the fact that what there remains of radio telecommunications is increasingly tight beam focused (especially long distance transmissions). Encryption is also doing its part, making any signal look like noise. Our radio noisy phase may soon be over altogether having only lasted a century or two even with just the technology we have today. It is also conceivable that there exists a telecommunications technology that is so much better than radio, landlines and tightbeams (instant, any distance/place, no loss, low power) that any advanced civilization discovers within a millenium or two of its bloom, that using radio would seem like using stone tools.
@talltroll7092
@talltroll7092 5 лет назад
Much depends on whether FTL is possible or not. If it is, then presumably the same basic tech can be used for FTL comms, rendering radio for anything other than planetary transmissions laughably obsolete. If it isn't, then it won't make a huge amount of difference who hears who; we won't be able to drop by and visit each other on any kind of reasonable timescale
@medexamtoolscom
@medexamtoolscom 4 года назад
That thought has merit, but I think it's not going to ultimately prove to be the case. There will always be some niche broadcasting at high power as long as human civilization doesn't fail outright. Why do I think this? Because when TV came along, people didn't shut down radio altogether. When cable TV and then the internet came along, people didn't shut down broadcast altogether. It may constitute a smaller fraction of what is done, but I think a substantial amount of high power broadcasts will be continued as long as civilization as you know it continues.

As usual the answer is just that we don't know how it works. Maybe Earth is a common example. But maybe it's an exception... in a way you wouldn't expect. Maybe most worlds with life are hosts to dozens of advanced civilizations created by different species at any time. Maybe they are all hiveminds that don't really care about life on another planets until it's too late. Maybe most civilizations destroy themselves in an nuclear war in the equivalent of our cold war. All of this, again, because we only have one data point on the graph, and that is Earth, and us humans. From there, we can only speculate AND seek for more data. What you're doing there is the common mistake of assuming that Earth is representative of how live works everywhere in the universe, and that humans are how advanced civilizations always work. It's a similar mistake to the ones made by european explorers who discovered ruins on other continents: they assumed that they had to be built by ancient europeans, because natives weren't advanced enough. They couldn't imagine that different models of civilization could exist, because all they knew was european civilizations.

i always think its wild to assume we're a 'young' technological civilisation, as we have no yardstick to compare ourselves to, and that we've been technically creating 'technology' since the ancestors of humans were smashing walnuts with rocks. and its also wild to assume that aliens will have receivers for our radio and light transmissions and will be actively listening. life could have a huge change of thriving on other planets for all we know, but there's a tiny chance that >the intelligent life is in any way similar to us even conceptually (silicon based life? cloud life?) >the life's intentions are similar to our own ("answering whether or not we're 'alone' in the universe" maybe exploring the stars is a very human concept) ETC. i think the chances of aliens creating anything capable of receiving our messages, or even using radio waves etc as a method of communication are so minuscule when we consider the universe of possibilities. i think among the trillions of stars there exists a creature out there somewhat like us that's listening for our radios and lasers and shit. but i think between them and us there's a trillion other creatures listening for infrared beams or antimatter radio or something. idk what fermi theory thing this is lol like we're trying to bluetooth connect but our nearest sentient life is trying to wifi and the one next to them is trying to connect their ps3 controller. they just cant hear each other. 😔 but eventually our radio bubble will get to that one people that's listening just like us! 🥰
@travelleroftheatlas4680
@travelleroftheatlas4680 5 лет назад
That's an interesting theory and one that I have come to wonder about myself. Is the reason we haven't found life outside of our solar system because we are strictly searching for life in our narrow definition of it? If we opened our minds to the idea that it is possible life exists outside of carbon based lifeforms, maybe we could finally find extraterrestrial species. In regards to the communication barrier, it is entirely possible other civilizations are trying to reach out to see if they are alone, but they aren't getting results because everyone is using a different medium. I found the analogy you used very humourous, btw! Of course, we must also question whether or not it is wise to put ourselves on the galactic radar when we have yet to venture beyond our home world in the effort to colonize another planet. If the first species we meet are conquerors, it would not be very difficult to fight a species that lacks the means to effectively escape their planet's gravitational pull, and our fate as a species would be up in the air. I could be blowing things out of proportion but to expect the first extraterrestrials we meet to be benevolent may be very, *very* naive. That said, we could encounter another species that genuinely just wants to know their cosmic neighbors. Another question, however, is are they already here? It wouldn't be that difficult to surmise that a technologically advanced species intercepted transmissions, decoded them, and is now actively monitoring our species. Some theorize that we have been getting visitors from the stars for generations, and we are only now realizing that folklore and ancient depictions of what our ancestors called gods may in fact be misunderstood contact with extraterrestrials.

Pending that, (and assuming the signal strength is constant between the two setups) does the size of the "anchors" of the interferometer determine the captured resolution of the signal or does the spacing? Lastly, would building one with 3 anchor points instead of 2 be beneficial? PS: shoutout for SETIatHome

Harlan Kempf Yup that's possible, they're already using a space-based telescope for interferometry. ( RadioAstron, 340,000km Orbit). All you need is a precise time reference when you compare the datasets from all telescopes used. From what i understand, the spacial resolution of an earth-mars-bases interferometer would be great, but in order to see faint objects (like TV-transmissions from aliens) you still need a huge collection area.

If our own technological progress is representative of other civilizations, then radio brightness may be just a passing blip. That is due to our radio communications becoming more efficient, using less power, moving toward higher frequencies and narrower beams, and use of digital modulation schemes (spread spectrum) which resemble noise. Additionally, over the air broadcasts are being replaced by wire or fiber delivery methods. Satellite radio and TV broadcasts use only a few hundred watts and are directed into a well defined footprint on Earth's surface, producing only feeble reflections into space. Even the use of planetary radar will become unnecessary as increasing numbers of planetary probes are sent to map and monitor the other planets in our solar system. Edit: this means that unless we transmit persistent, targeted, high power beams designed to be detectable and decodable, another civilization will probably not be able to "see" us. The same applies in reverse: we would only "see" radio signals from another civilization if they deliberately targeted our solar system.
@palomarjack7090

Finally, someone who knows what he is talking about. In my estimation there is only one way to find another civilization and that is their radar leakage. But at some point that will get replaced by something more suitable for travel beyond a planetary systems boundaries. So if they are 1000 ly away and we receive their first "1950s to 1960s" radar leakage they are almost 1000 years ahead of us, or gone from natural or artificial disasters. As for the former, probably have better things to do than repeatedly bumping into our own planet as the History Channel would have you believe.

It doesn't matter how big your telescope is, you'd need one the size of our entire solar system to do any actual detecting.

wouldn't our radio signals be too weak by the time they reach light years away? doesn't the strength of the signal depend on square the distance in diminishing in power?
@BroCactus
@BroCactus 7 лет назад
yes but if they had receivers placed in the right formation they could heavily amplify the signal. Similar to how we use formations of radio telescopes in Chile to see things we couldn't otherwise see

They would be weak, but still exist, and not match natural sources.

That's why the video notes you'd need a radio dish comparable to the moon's orbit. That's big, very, very big.
@garethdean6382
@garethdean6382 7 лет назад
SpyingDutchman There's a difference between *strength* being indistinguishable fro background and being undetectable, as well as just how small the difference from background is. Remember that light also weakens over distance at the same rate as radio, yet we can still see stars many light years away, even galaxies millions f light years away if we have sensitive enough equipment focused for long enough. There is no definite 'cutoff point', especially since in space signals don't scramble of degrade readily.

How does the accelerated expansion of the universe due to dark energy, if in anyway, effect these radio waves either broadcast by us or a hypothetical alien civilization, lets say, in a star system nearest to our own?
