IN THE BEGINNING, ABOUT 13.7 billion years ago, to be reasonably precise, there was a very, very small dot.

Just one thing about that “age of the universe” stuff. There are people who will try to tell you that the Earth is only about 10,000 years old; that humans and dinosaurs were around at more or less the same time, a bit like in the movies Jurassic Park and One Million Years B.C.; and that evolution, the change in the inherited traits of organisms passed from one generation to the next, does not, and never did, happen. Given the evidence, it’s hard not to feel that they’re probably wrong. Many of them also believe that the universe was created in seven days by an old chap with a beard, perhaps with breaks for tea and sandwiches. This may be true but, if it was created in this way, they were very long days: about two billion years long for each, give or take a few million years, which is a lot of sandwiches.

Anyway, to return to the dot, let’s be clear on something, because it’s very important. The building blocks of everything that you can see around you, and a great deal more that you can’t see at all, were blasted from that little dot at a speed so fast that, within a minute, the universe was a million billion miles in size and still expanding, so the dot was responsible for bringing into being planets and asteroids; whales and budgerigars; you, and Julius Caesar, and Elvis Presley.
