Sonyme Posted August 17, 2022 Share Posted August 17, 2022 I recently watched the two part series, Secrets of size, hosted by Jim Al-Khalili. The first episode discussed the very smallest things, atoms and their components and the second the universe at the very largest scales. Being a V.A.A. ( Very Amateur Astronomer ), I am left feeling a little confused. Jim describes a phenomenon known as a Supercluster and in particular one with the name Laniakea meaning immense heaven in Hawaiian of which we are apparently part of. In the simplest terms, all of the galaxies in our corner of the universe appear to be heading toward Laniakea. Now being a fan of Mr Brian Cox and the many space related programs he has produced, I'm sure I heard him say that everything in the universe will be so far away from everything else that if we were fortunate to survive the death of our star, etc, etc, we would look out into the heavens and see nothing but a black starless sky. Now, if Jim is correct, that would not be the case and perhaps we would ultimately be heading toward a 'big crunch' as I would imagine the forces involved in something as enormous as a Supercluster might eventually lead to a coming together much like the one that will happen when the Milky Way meets Andromeda....but on a completely different scale. If I haven't sent you to sleep, I'd be interested in your views, even if you think I'm missing the point! Gary Quote Link to comment Share on other sites More sharing options...
