This is a slightly faded memory, from a few years ago now, from the last time I was in the Outer Hebrides. It’s a late night, two in the morning or so, in August. You can hardly make out a thing in the darkness. There’s a crowd of us sat around in deckchairs, in the front yard of the University farmhouse, heads leaning back. We’ve all just returned from the “local” pub, about six miles away, and we’re sitting outside to watch for the Perseids. Out there on the Atlantic coast, the sky seems, strangely, lighter than elsewhere, because of the number of stars scattered across it. The sky is filled with patterns of light, coming from millions of years ago; and leaning back in a deckchair, the age, complexity and size of it all fills me with a slightly dizzy awe.* Every thirty seconds or so, a meteor flashes across the dark sky, and everybody watching smiles.
