Parallel Worlds


Parallel Worlds by Michio Kaku is a fascinating look at the the world of quantum physics and its place in cosmology. Although some of it went over my head (I ‘read’ this as an audiobook, so it was easier to loose concentration), I loved the explanation of quantum theory (particularly the stuff on observers) and the later chapters on anthropic theory (the fact that life doesn’t just exist in the Goldilocks zone of our solar system – Jupiter is just the right size apparently and in the Goldilocks zone of our galaxy, but we are in a myriad of narrowly defined ‘just rights’, some people believe this is proof of a designer, others see it as proof of a multiverse, that is if there are an infinite number of universes, then probability says that of course there will be a universe where the conditions are ‘just right’ for life and of course we are in that universe because we are observing it). The book will also be useful for next time Girl Lacer gets a dreamy look on her face and goes “But what came before the Big Bang?”, I’ll be able tell her possibly another universe or maybe it was made by an intelligent civilisation in another dying universe as a means of escape (as discussed in later chapters). The aforementioned later chapters look at how a future, advanced civilisation could escape our dying universe into one of the other parallel universes, forget your conventional sci fi, the possibilities are far more impressive! And it goes to show that whilst at the moment, it might be easy to wonder what the point of theoretical physics is, there is so much we still don’t know and it’s going to take a long time of finding out and as well as possibly providing an exit strategy out of our dying universe, who knows what benefits we can’t even dream about, could be found out. Kaku spends some time towards the end of the book talking about the categories of civilisations, we’re a 0.7 civilisation apparently but, as Kaku writes, we could make the leap to a type 1 civilisation within our grandchildren’s life times, or we could destroy ourselves. Watch Kaku summarise his ideas about the transition to a type 1 civilisation here, although don’t watch if you’re Nigel Farage, it might offend your itty bitty sensibilities.>

    1. I read Parallel Worlds for similar reasons, I haven’t heard of Brian Greene but I’ve just had a quick google and he looks good, will definitely check him out. I’m currently reading Max Tegmark, which is quite good to.

      1. Brian Greene has a new website call World science U full of videos about physics and space. I think its easier to understand when I watch rather than read.

      2. Ooh thanks for the tip, will definitely check that out. I’m finding Max Tegmark’s Our Mathematical Universe a bit over my head at times, Parallel Worlds was definitely more useful.
