Brian Cox - Alien Life & The Dark Forest Hypothesis

The renowned physicist and science communicator, Brian Cox delves into the topic of alien life and in particular, the question about intelligent alien civilization.
With his trademark enthusiasm and engaging style, Brian Cox explores the possibility of extraterrestrial life and why we haven't found any.
The video starts with a brief overview of what Brian Cox & astronomers call: "The Great Silence". Cox then goes on to explain the Fermi Paradox and the Dark Forest Hypothesis, which suggest that intelligent life may be intentionally avoiding contact with other civilizations to avoid being destroyed.
Cox uses his expertise in physics and astronomy to explain how alien life may be closer than we think. Like on the surface of the red planet, Mars. He discusses the potential for life to exist in other planets because there are at least 20 billion other earth like planets in our galaxy alone.
Throughout the video, Cox provides easy-to-understand explanations, making complex scientific concepts accessible to a broad audience.
Whether you're a science enthusiast or simply curious about the possibility of life beyond Earth, Brian Cox's insights and knowledge are sure to captivate and inform. Don't miss out on this thought-provoking and entertaining exploration of the universe and our place within it.

Given how long it can take for complex life to form, another possibility is that alien civilisations could be about as old as our own. In this case, we both only started looking out into space very recently. It's like placing 2 people on the opposite side of an empty earth for 2 minutes and asking them why they haven't found each other yet.

Nailed it. Brian Cox has spoken at length about this and it is his favourite theory.

The extremely stable conditions is overstated by some researchers, but not by all. We have received apocalyptic meteorites several times in prehistoric histpry and, according to some theories about the great extinctions, direct hits of gamma rays, that erased the atmospheric layers for several years. But life has shown that is very plastic, where a few microorganisms can survive at the bottom of a sea, life comes back and re adapts. A paradox about life is that it requires unstable conditions to generate the primordial elements.

[@Alexander_Kale]

The problem with the Dark Forest is that hiding would not save you. Imagine that there WAS a genocidal species out there. They would inevitably come to the conclusion that some species would try to hide from them, and they would then try and find ways to kill the ones that do. WHat is the easiest way to do this? Massive overkill. YOu have an incredibly powerfull energy source in the form of your sun. By weaponizing just a small part of it, you can absolutely kill every living thing in the galaxy without ever leaving your own solar system. If you repfer a more direct approach, send out fleets of probes equipped with nuclear bombs. Or just sent probe droids, like the ones from the second star wars movie, and tell them to report back. If one of them doesn't report back, send a kill fleet. In other words, you can rest easy. If there WAS a genocidal alien race out there, we would already be dead. The very fact that we are still alive means that we are save.

[@chromatic2006]

What is really terrifying is understanding why an advanced civilization would see a lesser developed civilization as a threat. It's because that lesser one might, upon being contacted, devote all of their resources to 'catching up". And scientific discovery is not a universal constant. It is possible that the lesser one gets really lucky, and is able to leapfrog ahead in science and technology. The greater civilization can't take the chance, they have to make a decision to eliminate now. Here we are on Earth, broadcasting our signal out freely.

The authors contend that simple, single-cell life, such as bacteria, is likely quit common in the universe, but more complex multi-cellular life may be exceedingly rare and so-called "intelligent life" (whatever that means) would be rarer still. Excellent, thought-provoking book for those interested in the subject. Spoiler alert: Don't hold your breath waiting for that signal from outer space.

Without asking for consent. 2) Imagine the knowledge and power such a future humanity holds. They would have incredible understanding of biology and physics. For all intends and purposes, if they are capable of interstellar travel, they can produce infinite amounts of energy. Would you really consider it ethical for such a species to sit back and watch as their objects of study engage in bloody wars for limited ressources? WOuld you consider it ethical and good for such a species to watch as their subjects struggle to deal with climate change, when you could give them access to unlimited, cheap, clean energy? Would you consider it ethical for such a species to sit by and watch as those people in their ant farm die in the thousands to diseases that you would consider preventable, when you could very easily mass produce cures for any and all of them? 3) Finally, imagine the cosmic joke. SOmeone on that planet looks up into the sky, wondering if they are alone. If there are other species out there, somewhere across the ocean of space.

[@bobdownie.2806]

A major rule in the discovery process is that we find something unexpected. Which is not surprising given just how little we have yet discovered. This of course doesn’t mean that I expect that the unexpected will come in the form of alien life, it means that anything unexpected is just so because it is alien to us. If we look at life from the perspective of biology we may be missing a broader reality of what in fact does constitute life. It may turn out to be that our bodies (by which I herein include our brains/minds) function for our own purposes…our own ends and therefore we do not see that which is beyond our own little world that our body is functioning for. Aliens could be all around us and we don’t see them….this is not so far fetched if you consider how magic tricks fool us. Alternatively you could consider the capacities of different species to have an awareness of things (E.G) a mole’s eyesight, a bats echolocation etc…..it’s extremely stupid to think our own ability to sense the universe is unlimited, despite technological aides. Again, I recall a certain species was believed to be extinct in Australia, until the so called experts asked the local indigenous peoples about these and were led to them in abundance. The bottom line is that humans are very limited in both intelligence and their awareness of the universe when compared with the immensity of what is out there……we will never know everything, this can only ever be arrogance……which is a fear response to that which is greater and more powerful than you.

So if you were to scoop a glass of water out of the ocean and you didn't find any fish, would you say that there was no life in the ocean?"

So I saw a couple of things that would make it hard for us to detect an alien Species. If an alien species is less developed then us, they would not be able to send our radio waves that are telescopes can detect. Plus the further the signal the harder it would be to detect, not that it degrades, but it becomes a thinner and thinner signal. Which is why one would need a far bigger receiver. If an Alien race was at our level it would still be hard to detect because the bigger telescopes receiver needed to detect those signals let a lone give them meaning. The other thing is modern technology does not use as much broad spectrum communication. We now use short range radio waves (cell phone, wi-fi, Bluetooth, and NFC), we also use a lot of medium to carry information such as: Twisted-pair, coax, copper, and fiberoptic cables. They're not just sent in a wife range like radio waves that are limited limited to the speed of light. If an Alien species were more advanced than us and they do eventually become space faring or even travelling casually through their own solar system they would need something faster than light to maintain proper communication. This makes me think that they have developed a far more advanced version of quantum entanglement. Example: If particle A vibrates than the entangled particle b would vibrate. the best part is there is 0 medium to detect because no matter the distant its instantaneous. Which would mean they can't be detected. I mean I would like to hope that other intelligent species in the universe would not be living in constant fear of other races. I can't imagine thousands of species that were gifted with self awareness or beyond would think in the ignorant, arrogant, selfish, fearful way we do as a species.

It's an interesting concept. Problem is, there is so much volcanic activity on the Earth on any given day, any Roman smelting of lead and silver would be virtually impossible to detect.

Because those tribes that tried could not completely elimiate the compention and sometimes ended up in stalemate.

[@robwhythe793]

One aspect I never hear discussed on this topic is the possible level of alien life's scientific advancement. We have been using radio for no more than the past 150 years. Before that, there would have been no technological signals being emanated from Earth that could have been detected by alien life elsewhere. And radio suffers from the problems caused by being limited to the speed of light. That affects us on Earth only by a second or so, as the time delay via a geostationary satellite, but as we explore our solar system that delay extends to minutes, hours, days as distance increases. Suppose an advanced alien civilisation finds a way to communicate in a way that avoids that delay: They would immediately drop radio and never use it again. How long will it take us to find such a way - hundreds, thousands, millions of years? Compared with the time Earth has existed, that's a mere blink of an eye. If alien life began elsewhere in our galaxy a million years before us, think how much further advanced they might be? They might be travelling past us in ships we cannot detect, or talking about us using communication systems we cannot even conceive. To expect them to be using technology similar to our own, or to be communicating using methods we could listen to is such a limited viewpoint. The sort of viewpoint that could suggest we could stop an alien invasion using a computer virus. No, think more of the enormous difference between us and aliens that Arthur Clarke envisaged in 2001 or Childhood's End, where the alien life form is truly incomprehensible to us.

Just a few questions (I can't answer them, but maybe someone else can?) 1. Would we necessarily be able to recognise an alien life form if we met it? What I mean is would it have to be observable to us in a physical sense, or could it even stand next to us without us knowing and not be detectable by our equipment? 2. Even if it were only a couple of light years away, would it necessarily be able to contact us or even want to? So, if it for instance was on a par with say a cow or a dog it wouldn't be trying to contact us. Then again if it was so advanced that it saw us as comparable to the primitive life forms of its own planet, would it even bother? 3. Could an advanced life form exist inside our own planet? I don't mean 'Hollow Earth Theory' more like hollow areas. 4. Does the universe have to be how we observe it, or could it be an illusion of some kind?

Technically fire is a living breathing entity so I think yep we probably passed life by at some point

[@Trusteft]

1. Yes, if we met it. If it's part of the physical world yes we would in some way be able to observe it. Yes it could stand next to us without us knowing it was there. 2. Yes or no, it depends, there are humans who want to contact aliens and there are humans who don't want aliens. That is just among one species. So more species who knows how they see the possibility of contact with other species, probably there is a variety of approaches depending on the species. If it saw us as a primitive life and wouldn't bother, should we bother? 3. No. Physically impossible. 4. Yes the universe has to be how we observe it, unless proven otherwise. If proven otherwise then the universe is how we would then observe it based on our updated knowledge of it. If you are asking if the universe is a construct, a virtual world or something like that, then my answer is probably not. Unless we find proof to the opposite.

1. We are specifically searching for life similar to that on Earth because that’s the only thing we are certain we would even recognize as life. There may be other life in the universe that is so unlike ours that we would not be able to tell. So yes, it absolutely could be undetectable and unrecognizable. 2. I think it would probably depend. And I think that could potentially be a big reason we haven’t found anything yet. Just because humans share connection and curiosity does not mean another intelligent life form would. There could be many reasons why a civilization would not want to interact with us or be found at all! 3. Not advanced, but undiscovered for sure. The majority of the deep sea has not been explored, and I imagine that there is plenty of life down there that has never been seen before. However I don’t think it would be possible for something more advanced than us to live so close and be undetected. 4. I don’t really have the answer to this question! I guess it would have to be how we observe it, but at the same time, there is so much we don’t know about the universe. Our observable part of the universe is so small. We do know that the laws of physics must apply the same way throughout the universe, but things like black holes are still partly unexplainable. I don’t normally comment on KZbin videos but I’m really interested in this stuff and I hope I was able to help!

The universe is so insanly incomprehensively large that we simply haven't been looking for long enough. Maybe life is really that rare...scary thought.

It’s our limited technology that prevents us from understanding how to find or understand why we have not found other life

[@The1stDukeDroklar]

Bull. Given the vast time the galaxy has been here, any advanced alien specie would most likely be millions if not billions of years older. It would only take about 1-2 million years to colonize every planet in the galaxy at sub-light speeds. IF there actually were other alien civs in the milky way, you wouldn't have to ask where are the aliens... you wouldn't be able to swing a stick without hitting an alien.

[@Westrait]

@LucYfYre Arch of TwiLight True also since the singularity hypothesis, of big bang there should be older Civilizations since time and space is going in a linear fashion still we don't see anything ...with our scopes or satellites...not one hint ...Intelligent life seems rare if you try and match up our solar system with the many others it would all have to be a exact identical orbital alignment , size of planets moon, and Sun anything off would throw any hopes of any life...We were almost wiped out ourselves during the age of Dinosaurs. Asteroids and metoers seem to be the culprit for non intelligent life and million other things with evolution,temperature,chemical reactions ,planetary alignment,etc

[@The1stDukeDroklar]

@@Westrait Yes. Not only does earth possess a multitude of things that seem to be pretty rare, but as you pointed out, even here life has been very tenuous to put it mildly. IIRC there's been 5 global mass extinction events that we're aware of. All of these things are "filters" to the possibility of life, let alone life that survives long enough, in the right conditions, to develop technology. Even on earth which is pretty primed for life, intelligence of human level appears to be a freak occurrence since we're the only species that has evolved it out of the countless species that have existed over billions of years. Given all these things, odds are we are the progenitor species of this galaxy. If that turns out to be true, it places a heavy responsibility upon mankind to not go extinct. In that case, it would not just be the fate of humanity at stake, but of all future life within the galaxy that we would spread as long as we survive.

[@Defalto]

The “WOW” signal reminds me of how we distract cats with a laser pointer. Some primordial space gods out there are maybe just toying with our instinct to curiosity, the breadth and depth of their knowledge and technology completely unfathomable to us, the equivalent of a pet cat to its owner. Pretty terrifying.

[@romino23]

Finding alien life is like finding life in Stok-on-Trent, we hope it is out there but finding it is a challenge.

Saying "finding intelligent life" maybe would've made that dig funny. As it stands you failed. Quite ironic
