While I walk I often ponder things. There are two photos that recently appeared on the Astronomy Photo of the Day website. The above photo was take by the Hubble Telescope of two galaxies tearing each other apart.
And this photo is of the new CERN cyclotron which will soon tear subatomic particles apart. What amazes me is how come we humans seem to be located right in the middle between the very large and the very small. Anyway, that's one of the things I like to ponder as I walk along.
