Sun shadow...

khiemtranThe sun is a very long way away. I've known this for a long time, but just this week I had an interesting practical demonstration
I was walking on a path near the Uni on a bright day, and I noticed a shadow approaching mine from one side. I turned my head to see who it was, and there was no-one there. The shadow was from a person walking on a pedestrian bridge above and behind me, a good twenty or thirty metres away (it was hard to tell who it was exactly because the sun was directly behind them). Obviously, twenty or thirty metres counts for nothing when compared with the distance from the sun to the earth, so the person's shadow (I still don't know if it was male or female) was roughly the same size as mine, and it looked exactly as though someone was walking up behind me.
Of course, I think it was a person on the overbridge...
