One way or another, this is a deeply misleading Universe. Wherever we look it’s beginning to be extremely alarming and extremely upsetting to our sense of who we are—great, strapping, physical people living in a Universe that exists almost entirely for us—that it just isn’t the case. At this point we are still divining from this all sorts of fundamental principles, recognising the way that gravity works, the way that strong and weak nuclear forces work, recognising the nature of matter, the nature of particles and so on, but having got those fundamentals, we’re still not very good at figuring out how it works, because the maths is really rather tricky. So, we tend to come up with almost a clockwork view of the way it all works, because that’s the best our maths can manage. I don’t mean in any way to disparage Newton, because I guess he was the first person who saw that there were principles at work that were different from anything we actually saw around us. His first law of motion—that something will remain in its position of either rest or motion until some other force works on it—is something that none of us, living in a gravity well, in a gas envelope, had ever seen, because everything we move comes to a halt. It was only through very, very careful watching and observing and measuring and divining the principles underlying what we could all see happening that he came up with the principles that we all know and recognise as being the laws of motion, but nevertheless it is by modern terms, still a somewhat clockwork view of the Universe. As I say, I don’t mean that to sound disparaging in any way at all, because his achievements, as we all know, were absolutely monumental, but it still kind of doesn’t make sense to us.
