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.

    Aliens: "Greetings! We send this message in an attitude of peacefulness." Us: "Your able to communicate in English?" Aliens: "You're"
  • Just because we haven't found them, doesn't mean they haven't found us.
  • @Greenishprint
    The way we search for Aliens, not even knowing they are friendly, is absolutely terrifying..
  • @chrishernandez8504
    The fact that we have looked at what is equivalent to a cup of water from the Pacific sea of space and some people throw up their hands like "well we looked in this cup of water of space and found no intelligent life so intelligent life isn't possible " is one of the most insane proposition in science
  • @arron911
    It's wild to think that even if a signal was sent at the speed of light from an advanced civilisation a million light years a way, by the time we receive it, that same civilisation could have been extinct for hundreds of thousands of years.
  • @sagan1976
    The way the Dark Forest is presented in Lin Cixiu's books is amazing.
  • @KennethEvans-uf7hc
    "it could be that we're the only island of meaning in an ocean of 400 billion suns." I love how scientists and science can be so effortlessly poetic and beautiful without trying.
  • @deis.w
    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.
  • Vast distances, the limited speed of light, extremely specific stable conditions, and our own lack of ability to reach/message even nearby stars, all easily explain the Fermi paradox for me.
  • @jmlaw8888
    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.

    I think it's pretty damn special to live in a universe on a planet at a time when Brian Cox is alive to share his knowledge and enthusiasm. šŸ„°

  • @troubadour723
    To think how unique we might be in the galaxy and yet how self-destructive we are is extremely depressing.
  • @dennishrmn1
    I don't think there's anyway possible that we are alone. The size of the universe is inconceivable, in the amount of planets orbiting suns seems almost endless.
  • @sandrewss92
    Brian Cox could put you in a youtube coma for hours listening to him he's fantastic at simplifying science for us.
  • @EFCDKZ
    The dark forest theory is funny to me. I can just imagine other civilisations wondering why we want to be found so much and are just shaking their heads at us knowing weā€™re gonna get extinguished šŸ˜‚
  • @Chimera_166
    Brian is so enthusiastic and over the top happy when it comes to these things
  • @Samurai78420
    I could listen to this guy for hours. Love it.
  • @romino23
    01:34 It took humans nearly 4 billion yrs to become who they are, that's the third of the age of the universe... mind blown.
  • The absolutely mind-blowing concepts presented so succinctly for mere mortals like me by Dr. Brian Cox and Co. are so very much appreciated. Cheers from Melbourne šŸ‡¦šŸ‡ŗ
