The curious incident of the dog in the night-time

«I looked at the sky a lot. I like looking up at the sky in the garden at night. In summer I sometimes come outside at night with my torch and my planisphere, which is two circles of plastic with a pin through the middle. And on the bottom is a map of the sky and on top is an aperture which is an opening shaped in a parabola and you turn it round to see a map of the sky that you can see on that day of the year form the latitude 51.5º North which is the latitude that Swindon is on, because the largest bit of the sky is always on the other side of the earth.

And when you look at the sky you know you are looking at stars which are hundreds and thousands of light years away from you. And some of the stars don’t even exist any more because their light has taken so long to get to us that they are already dead, or they have exploded and collapsed into red dwarfs. And that makes you seem very small, and if you have difficult things in your life it is nice to think that they are what is called negligible which means that they are so small you don’t have to take them into account when you are calculating something.»
