Will there forever be stars in the sky? Will humanity roam the cosmos for eternity? What does the future hold for our Universe? This is a journey through space and time, from galactic collisions and hyperactive black holes, on to the death of the last star.

    Oh, and Ri, since my kids were little, we've been listening to all these wonderful Ri talks, and now they are teenagers, and still like them, as do I

    I was asleep and this video appeared on my list and I gave it a Play ... I enjoyed every second and now I can't sleep. I think of everything Mr. Geraint Lewis said ! I learned a lot tonight. Thank you very much !
  • @tappajavittu
    To everyone who enjoyed this lecture and doesn't know about Geraint Lewis' and Luke Barnes' youtube channel Alas Lewis & Barnes, I'd highly recommend it for anyone interested in cosmology, good stuff!
  • @boxelder9167
    This was so encouraging. Finally I got the assurance that I needed that eventually all my enemies will be dead and I won’t have to ever pay taxes again or listen to politicians give non-answers to the people that they were hired to represent. Ahhhh! Peace at last.
  • @Dss-bm3rz
    I can't get enough of these intellectual conversations, it's the one thing that actually stimulates my mind and gets my neurotransmitters pumping. Thank you guys.
  • @brianhubis3988
    This one is so good, my favorite so far. I will actually watch this one more than once.
  • @afterthedrjay
    So glad the audience wasn't interrupting Mr. Lewis' presentation. They were actually listening to him and the concepts he presented. The Douglas Adams line was a great thought provoking ending. I loved this presentation and the speaker.

    not just gorgeous ( a real silver fox!), not just gorgeous AND intelligent, not just gorgeous, intelligent AND a superb communicator - but gorgeous, intelligent, a superb communicator, AND Welsh! A quadruple whammy....what a joy to find this series.

    Why haven't I heard of Lewis before?! This was beautifully clear, nicely constructed and delivered with just the right amount of dry humour. Oh, and I read Black Cloud 50 years ago and hadn't thought about it until last week. Now here it is again. Miraculous.
  • Being an enthusiast since the age of 6 and now watching this, makes me want to leave my digital marketing job and study cosmology full-time. I wish life were that easy.
  • I'm reminded of the Peter Cook line. "Still, there is hope. I hope this will not happen."
  • @davidbrown8303
    I wasn't worried about what I'm what I was going to do ten billion years from now till I watched this show.
  • @SoundsOfSushi
    I wish my college astronomy class was this informative.
  • @davidsavage6227
    So well-spoken and a pleasant conveyance of complicated information, with great graphics.
  • @88pampa
    beautifully communicated, I enjoyed this lecture very much!! Thanks to the RI for putting on these lectures, and thank you to Geraint Lewis for a great talk!
  • outstanding lecture. I have learnt so much from this guy in the last hour than I did all the way through school. wow I actually feel more clever than I did an hour ago :)
  • @sj5669
    One of the most fascinating and stimulating presentations I have seen. It will be survival of the fittest for sure in the end.
