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.

As is considering all of the thousands of UAP sightings as the reports of fools or charlatans because interstellar distances are too great. We now know that the US military believes they are real, and has for decades. We also know they have had disinformation campaigns for decades. Science has a nasty habit of disproving previous theories. There is a reasonable chance that current theories also eventually will be proven to be wrong.

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. Edit: I said it's one POSSIBILITY out of millions and billions of other possibilities.

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.

I personally look at it as seperately picking two people anywhere on earth throughout the history of human civilization and expect them to meet eachother - only ridiculously more difficult. What are the odds that they will be born within the right timeframe and distance and with the ability to actually meet? If there is life out there its likely died before us, will live after us or if actually alive now is so far away we will both be gone before we could ever make contact.

Nailed it. Brian Cox has spoken at length about this and it is his favourite theory. There may be numerous other civilisations in the galaxy, but time is so vast, that it would be easy for one to exist for a million years and never see or hear another one. He relates Fermi to Drake and explains why this is a very likely conclusion.

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.

I mean, consider for a second the implications of what you just suggested. 1) In our society, observation without consent is very much a crime. Espionage between nations is very much a necessary evil. If a government agent wants to read your emails, he needs to justify that before the law, and in order to do that, he needs to show credible proof that you harbour hostile intent. You are effectively suggesting that future humanity of yours to do that. Spy on people. For thousands of years. Unsupervised. Without justification. 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. Meanwhile, your future humanity is sitting behind their stealth fields, laughing at him while they wave.

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.

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.

Universe seems old but its only 13.8 billion years old, Earth formed 4.5 billion years ago, single cell organsism appeared 3.5 billion years ago, AND then multicellular animals appearwd 600 Million years ago, then starting with Tesla in 1899 in Colorado Springs upto nowadays we have slowly been really just starting our search finding evidence of alien life. So yeah, we just might be a very early alien life that is looking for others And the amount of other advanced lifeforms could be rare and very spread out. Sucks, but real possibility.

For all we know they are near the same development as us. Barely poking a toe off the planet, or maybe still working a few centuries back in equivalence. Maybe they've already passed us and hit the terminal point for their species lifespan. Just because they are out there doesn't mean they are even trying to move off planet, maybe they don't wanna. Not all peoples are explorers on this planet either. If they are advanced like we seem to be determined to project and the only ones we have encountered so far are rowdy youngsters with a new driver's license. They could be social outcasts for their tendency toward strange 'experiments'. Maybe they don't want to meet us - we are far from united as a race, we kill each other all the time. The 'take me to your leader' trope doesn't fly when there are so very many without a top council or person to go to. Delightful to think about meeting someone from Out There, but I'm not holding my breath until they arrive.

yeah its travel, we need a faster and safer way to travel. We have tech to go to the moon and walk on it, but no one has the bus fare to do it like they did back then. Hence why Mars is off the menu at the moment, i recon if there was a big enough drive like it was to the moon, i recon we would have been there, in the 80s or in the 90s.

@@hellenespirit6009 Moon landing project, i think the US government just threw endless pots of money at NASA. But as soon as they landed on the moon a few times, budget was cut, so no more new moon walks. Also i think there isn't the drive either, like there was for getting on the moon and back. If a government hungry enough to go to mars, and back. I recon we would be there in the next 5 to 10 years.

There was an interesting question posed to one of the researchers at SETI. She was asked: How much of space have we searched for life?" Her answer was: "If you imagine that all of space is equivalent to the oceans here on earth, we have searched about a glass of water. 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?" Now obviously you could argue, throw it under a microscope and likely you'll find micro organisms, but the point is space is gargantuan and we've barely scratched the surface.

The Dark Forest hypothesis propose that an alien civilization will at first search for life on other planets. At some point they become advanced enough to realise to their vulnerability to other alien civilization and as a result becomes Dark.

Whilst an interesting hypothesis, it is ultimately irrelevant. Why? You may ask, simple really; for the planet Earth is the *only* populated planet in existence. And all the studying, all the searching, all the probes being sent out in scanning for evidence of life; Two now in interstellar space. Alas, Tis But an exercise in futility. That said, Thank-you for all the amazing images from Webb, Hubble (particularly Hubble deep field) . This small piece of dark sky when looked at, the astronomers expecting little in return were stunned to learn and see!! Thousands of galaxies!!!!!! So what’s beyond that? What’s beyond these thousands of newly discovered galaxies?? If (and they’re not) were an astronomer using their Hubble or Webb or better, way out there in *newly discovered* ‘Hubble deep field land’ and those telescopes were pointed at a ‘dark patch’ of their relative Sky, what on Earth would those Super mega telescopes wayyy out there observe What would they see? The answer is absurdly simple!!!. *NOTHING but, more and more and more ‘Deep Field* images of just more and more Spiral etc galaxies like our own Milky Way. *Beautiful for sure, but like the rest of the Universe with the exception of our Blue Beautiful Planet; Utterly devoid of life. *So Guys n Gals, get out there look after our world and treat it with the Love, Respect and Reverence Tis due* *I give you this unasked for reality, but give it I Must*

If you look at our own transmissions from Earth over time, they increased as we discovered and started using radio, but now that we're advancing our technology further were getting quieter right? So the duration of our interstellar broadcasts is what, less than 200 years? (accounting for the future too). Is it not simply possible that technology advances so quickly that they're only visible briefly. They done need to be actively hiding, perhaps they're just super efficient.
