Looking into the trees in Pond Wood, it isn't possible to see beyond. There are trees in every direction. This made me think of Olber's Paradox. This says that if the Universe is infinite, there should be a star in every direction and therefore the sky should be white. The sky is black so the Universe cannot be infinite. These days I think that is taken to mean it is finite in time because the distance we can see is determined by long the light has had to travel.
