  • We now know of thousands of planets orbiting other stars. But we know of only planet that hosts life - the Earth.
    Most scientists think that life elsewhere in the Universe is likely to exist, but so far there is no evidence that extra-terrestrials exist or that they have visited us. However, we can search for signs of life on distant planets and we are even using radio telescopes to look for messages sent to us by extra-terrestrial civilisations. In this talk Tim will discuss the latest science behind the search for alien life.
    Tim is a Professor of Astrophysics and an Associate Director of Jodrell Bank Centre for Astrophysics at The University of Manchester.
    Tim’s research concentrates on the study of exploding stars using telescopes around the world and in space, working across the spectrum from radio waves to X-rays.
    Tim is passionate about astrophysics and its power to inspire. Well known for his regular contributions to science on TV and radio, he is Jodrell Bank’s host for the hugely popular BBC TV Stargazing Live series and has a monthly space discussion programme on BBC Radio 5 Live.

    In 2014, jointly with Professor Teresa Anderson, he was awarded the Kelvin Medal of the Institute of Physics for innovative public engagement, and in 2016 he was elected as President of the UK’s Society for Popular Astronomy.
    This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at ted.com/tedx

      "It is the only substance that WE know about"
      Only substance that we know about? I'm pretty sure water is not the only substance we know :)
      Other than that, every substance stable enough and present in our galaxy would also be present on Earth. Earth is not an isolated system. Matter from our entire galaxy is constantly bombarding Earth in the form of dust and little rocks. When large enough comet hits a planet, some of the matter of that planet is ejected into space. There's not a substance in our galaxy that hasn't been shared across its entirety. Every planet contains some trace amount of matter from every other planet in our galaxy.
      Is that like a news flash for you or what?

      If we are not alone in the universe it is only terrifying if that being, God, is not loving.

    • @CatholicK5357
      @CatholicK5357 5 років тому +9

      @Clout Lord That would only make sense if we were 'alone' in the universe. My statement was based on the presumption that we are not alone, meaning that God does exist and is either good or bad. I have reason to believe He is good. Though I do agree that the concept of God not existing would be quite terrifying, which is certainly something that kept me up at night as a child.

    • @CatholicK5357
      @CatholicK5357 5 років тому +5

      @Clout Lord As I said, my statement was on the presumption that we are not alone in the universe. If you want to base an argument on the opposite assumption then that is your affair. I do not believe personally that it is possible to have no God, but my belief itself is not enough to remove impossibility. It is either impossible or not regardless of me.
      Good and bad are only human concepts in the subjective sense, meaning that we as humans, with often clouded judgement, change our minds out of convenience, needs, and wants, as to what is good or bad. Someone will justify murder to themselves if it benefits them and suddenly it is a good - or even on a societal level. However, good and bad in the objective sense is certainly not a human construct because it goes beyond our blindness. Objective morality has only come to us by means of religion, which the religious believe to be sent by God himself. Considering how self-denying all of God's laws are, if we are talking about the Christian faith, it would seem unlikely to me to be a human construct. No one in the right mind would deny themselves pleasure (if on a surface level seems to harm no one) unless they were told it was wrong by something beyond themselves, and unless they thought there were consequences not only in this life but in the next.
      An example of this would be fasting. Many religious have fasted rigorously, not for health benefits, but to deny their own flesh in order to become holy. There is no way that humans, who love pleasure, would ever come up with such a thing unless necessary for health reasons (other than a small percentage of crazies). And the argument that all religious are insane does not quite work either for obvious reasons that I hope need not be explained.
      Maybe He's in another galaxy? You clearly no nothing of the concept of God, who is beyond time and the material universe. Why do skeptics always mock faith? That is a rhetorical question by the way. If you wish not to believe then that is your choice. But there is no need to mock me with such a ridiculous premise of God. If God were inside space and time then He would not be God obviously, at least not the Christian one.

      Any intelligent being that has developed the technology to travel the immense distances between habitable bodies in space--and nonliving drones with the ability to interact with and learn about interstellar or intergalactic space during the voyage would probably be what is traveling those distances--would most likely not be impressed with the human race. Humans might be given about as much respect as humans do to bacteria.

      "It needed to be said again." True. Also, 40 years ago the chorus was 'give us the technology and we will find the evidence.' Well, we are developing the technology, so it is valid to ask 'where is the evidence?' Absence of evidence is not evidence of absence, but maybe it hints at it.

      The Drake Equation only calculates how many civilisations we should be able to detect. I've seen and heard several figures thrown around, someone even suggested that even with the lowest possible "settings" the equation came out with around 10,000 civilisations out there in our Galaxy alone.
      With all that possible life you would think we would be able to hear something and yet our heavens are silent.
      So we are left with a few possibilities:
      A) We are indeed alone in the universe.
      B) We are the first civilisation to reach our current stage of development - A very scary thought!
      C) Other Civilisations have developed different methods or more direct ways of transmitting information.
      D) Other civilisations know something we don't and have adopted radio silence in an effort to hide their existence.

For discussions sake, lets also assume they are in similar types of galaxies and locations within that arm of their galaxy and orbiting sun like stars like our own, etc. Most of them would likely be expanding away from us also as the universe itself expands. My question would be, how long would it take for us to detect a signal coming from their planet if we knew where exactly to look?

    • @skytrainii8933
      @skytrainii8933 7 років тому +3

      John, let me make one small yet very significant change to your first statement. The Drake Equation only calculates how many civilisations we should be able to detect if all the assumptions the terms represented are true and correct. As we learn more and more about our local solar system and our local view of the universe, we necessarily make changes to the values of the term and even the terms themselves. As we view more and more exoplanets, we will have to make changes to the equation.
      Right now, however, the equation does not represent our current evidence and observations. In other words, the equation says one thing and we have nothing. But we must keep looking because what we find will point to the truth; whatever that truth may be.

      Narrow band of time to develop technologically from Stone Age to where we find ourselves today. So Stone Age lasted 3m years until 4000 years ago when we started working with metal. Electricity hasn’t been around for very long. Flying has only been around for 100 years and 60 years after it was invented, we were walking in the moon. It’s exponential. We also exponentially develop weapons to use against each other. One exponential curve will negate the other. If good tech wins, our technological development will accelerate. If the bad technology wins, our civilisation will become the myths carved into stone for future civilisations to discover. Other worlds would have a similar path. They’d only need to be 300 years further along the good exponential curve to be so far advanced we’d call them aliens.

    @nathanielberkeley-biggs2855 5 років тому

    This is so simple to work out?
    1: The numbers of inhabited planets out there is so huge it is beyond our comprehension. It is into hundreds of quadrillions.
    2: Given that humans in terms of design are just a logical response to environment, it is likely that every ‘Earth twin’ will follow a similar process and give rise to similar life forms and the same evolutionary pattern. So there are zillions of ‘human types’ out there.
    3: Given that ‘human type’ or other ‘types’ are so common the numbers make it virtually impossible to visit each one? And why would anyone want to? When they are all pretty much the same?
    4: distance is so great that even 100 quadrillion (15 zeros) advanced civilisations scattered across the universe would seem to each other ‘where is everyone’
    5: the percentage of advanced civilisations that have solved intergalactic travel is going to be so tiny compared to the number of inhabited planets, and with inhabited planets being pretty much the same in many cases, it’s going to be unlikely that anyone will ever be visited, and most inhabited planets are likely to be of little interest.
    6: if you are a galaxy hopping advanced civilisation, then you are only going to be interested in species that are highly unusual or different, and as our planet isn’t particularly unusual, then it’s hardly goi g to give rise to any life forms that billions of similar planets have not also produced. Truth is, we don’t hear from anyone because we are not particularly special and we haven’t heard anyone else yet because we have only just started to listen.
    To us life seems rare, that’s because of the distances involved and the scale of the universe as well as our technology limitations. But to another species that has mastered travel life is going to be incredibly common because they can see the whole. So why would we imagine for a second that with access to everything that we would stand out in any way and be of interest as our civilisations is just one ant among trillions of ants. An advanced civilisation’s perspective is going to be completely different to ours.
    This is entirely my own theory. If we want to answer this question then we have to first consider whether we have the answer now (already being visited) , or.......we listen and look harder, or we make ourselves more interesting than the other trillions of unremarkable planets with bipeds walking around on them in different stages of development so widely scattered across our universe.
    Looking for Earth type planets and focussing on water and oxygen and habitable zones is entirely sensible as we know to some extent what life designs such planets produce through environmental response and evolution. If we were entirely an ocean planet for example we wouldn’t have legs, and we know that if something flies then it needs to follow the laws of symmetry and aerodynamics. Design is a universal principle, and at least we can predict what sort of life this sort of planet produces.

Life is easy to come by on earth. There's a bias that abiogenesis is inevitable because that's what happened on earth. In fact abiogenesis is so statistically unlikely that even this vast universe isn't nearly big enough for it to have beaten the odds for it happening twice in one universe.

    The simple way to get a mental scale as to the immense distances for interstellar travel is this:
    The earth's circumference is just under 28000km, so light can travel around the planets circumference more than six times in a single second. It takes approximately 8 minutes to get to the sun at that speed, but at that speed it would take 3 YEARS to reach the very nearest star, Alpha Centauri. Some of the most distant galaxies that we can possibly see are between 60 to 150 MILLION YEARS AWAY AT THAT SPEED, ON TOP OF WHICH IF THE EXPANDING UNIVERSE THEORY IS CORRECT IT'S GETTING BIGGER EVERY SECOND.
    The human brain simply doesn't have the capacity to fully appreciate exactly how big the universe(s) is/are, especially seeing how the latest science supports multiple universe/dimension theory. The fact that D-wave quantum computers actually exist and work right now basically prove that theory correct.

    We could do this by implementing a protocol including confining our
    interactions with them on a- one subject at a time basis (No more than a
    few individuals at a time) Further we would want to quickly disable
    them (Employing A quick an effective way to physically paralyze them
    while not effecting their ability to think and respond to our request.)
    And 2 : To maintain our non interference policy ; We would want to use a
    drug or other method to blank out their memory of our interaction with
    them; as this would prevent any individual "Trauma" and further avoid A
    possibly negative interaction (Unpredictable consequences)with the
    society as a whole.

    I'm personally not so interested in whether or not there are extraterrestrials, but there is definitely compelling evidence of aerial technology that has been witnessed and filmed that significantly defies any known aircraft that we have. I've witnessed myself on a few occasions these and they had no wings or any characteristics of any aircraft I've ever seen. One sighting I had was a very irregular shape and was rolling around in all directions, all the while going at a terrific speed

    Doesn't this guy have an Internet connection at home?
    Jees, put your textbooks away and do some research! It's the 21st century buddy, and the Aliens are here! You even carry some of their genetic material. 😂

    Every time I see a human being I see an alien cuz people treat each other like they're from another world
