Alien Faces In Our Universe - Documentary [1080p] Extraterrestrial Life


    Description

    Extraterrestrial life:
    Our cosmic horizons have grown enormously over the last century, but there is a definite limit to the size of the observable universe. It contains all the things from which light has been able to reach us since the Big Bang, about 14 billion years ago. But the new realisation is that the observable universe may not be all of reality. There may be more beyond the horizon, just as there’s more beyond the horizon when you’re observing the ocean from a boat.

    What’s more, the galaxies are likely to go on and on beyond this horizon, but more interestingly, there is a possibility that our Big Bang was not the only one. There may have been others, spawning other universes, disconnected from ours and therefore not observable, and possibly even governed by different physical laws. Physical reality on this vast scale could therefore be much more varied and interesting than what we can observe.

    The universe we can observe is governed by the same laws everywhere. We can observe a distant galaxy and see that the atoms emitting the light are just the same as the ones in the lab. But there may be physical domains that are governed by completely different laws. Some may have no gravity, or not allow for nuclear physics. Ours may not even be a typical domain.

    Even in our own universe, there are only so many ways you can assemble the same atoms, so if it is large enough it is possible that there is another Earth, even another avatar you. If this were the case, however, the universe would have to be bigger than the observable one by a number which to write down would require all the atoms in the universe. Rest assured, if there’s another you, they are a very, very long way away. They might even be making the same mistakes.
    So how likely is alien life in this vast expanse?

    We know now that planets exist around many, even most, stars. We know that in our Milky Way galaxy there are likely millions of planets that are in many ways like the Earth, with liquid water. The question then is whether life has developed on them – and we can’t yet answer that.

    Although we know how via Darwinian selection a complex biosphere evolved on Earth around 4 billion years ago, we don’t yet understand the actual origin of life – the transition from complex chemistry to the first metabolising, replicating structures. The good news is that we will have a better idea of how that happened within the next ten or 20 years and crucially, how likely it was to happen. This will give us a better understanding of how likely it is to happen elsewhere. In that time, we will also have technologies that will allow us to better search for alien life.
