    Is anyone else watching this? It's a four part series with Brian Greene. Tonight I was watching the "Quantum Leap" ep. Most of it was way over my head, but it is fascinating.

    Someone else was telling me about it but I don't get PBS in my area (OTA only). Do you know what the 4 parts are titled so I can try to find them elsewhere?

    Yes.

    "What is Space?"

    "The Illusion of Time"

    "Quantum Leap"

    "Universe or Multiverse"

    I've always enjoyed Brian Greene's presentations. He tries to make the material accessible to those of us who aren't theoretical physicists. :)

    I have read the book ... which is one my all time favorites. Video adaptation of it here is a bit clumsy and has far too many unnecessary graphics/props, and a lot of content is glossed over (possibly due to necessity). It is still pretty compelling though, and Greene has done an excellent job with layman portrayal of concepts that are easier to describe using math.

    The book is a highly recommended read for anyone fascinated in this topic.

    I've been watching all of them. Mind blown. :)

    I'll have to put the book on my wishlist.

    I would recommend his first book, The Elegant Universe, also a Nova series. It doesn't have same thematic thread (exploration of what Space is) but a interesting even if slightly outdated overview of string theory and theory of relativity. Its a good primer which helps with second book.

    And they are available as Kindle editions!

    I wonder how it would work as a Kindle edition - Greene marks many of his concepts that need more 'sciency' description with a number. You can then get science content linked to that number from a large appendix at the end of the book. Some of it is pretty interesting too. Does Kindle allow for cross-referencing?

    I love these shows. Even though I don't fully 'get' the math or science behind it, I love this stuff. I'm reading the universe/multiverse one (The Hidden Reality: Parallel Universes and the Deep Laws of the Cosmos) now on Kindle.

    I think I read in it or somewhere else, current theory is that there are ~ 10^500 universes. Within each of those, there are ~ 150 billion galaxies, and within each of those galaxies there are some large number stars (Milky Way: 200-400 billion) and possibly planets orbiting a large number of those.

    I'm going to take a WAG and say 25% of those stars have planets orbiting them, so after some admittedly bad assumptions and math:

    (10^500)universes * (150 billion)galaxies/universe * (200 billion)stars/galaxy * (.25)

    = (3*10^522)*(.25)

    = .75x10^522

    = 7.5x10^521 planets

    another guess: 1% of those are capable of supporting life

    = 7.5x10^519 life-supporting planets exist.

    Hopefully, someone way better at math can check my work. Everyone is free to challenge my assumptions. :)

    Also, there's the Drake Equation.

    N = R* fp ne fl fi fc L :)

    He only considers the number of intelligent civilizations in the Milky Way, though. About 10,000. (In this Universe).

    I have the first 3 recorded but haven't watched them. I did watch about 10 minutes of the first one back when it aired and I know I'm going to love it all.

    We're counting parallel universes? Wouldn't we only care about life in our own universe seeing as how we don't have access to any of the others?

    Also, since there are only something like 2.5 x 10^89 elementary particles (neutrinos, quarks and the like) in the known universe, which is a number vastly smaller than your number of planets that can sustain life, I think your math can't be right.

    You can also stream the episodes online, from Nova's web site.

    I've been watching these. Fascinating stuff. Some of the concepts are hard to grasp.

    I can only imagine what would happen if you took some LSD and tried to watch this. :eek:

    The Chuck Lorre vanity card for Two and a Half Men gave a shout out to the series (Greene did have a cameo on Big Bang Theory).
