Movement & Change: Constant!
The Earth is not at rest. It orbits the Sun, which in turn orbits the center of the Milky Way Galaxy, which in turn moves within the Local Group of Galaxies - a collection of about fifty four galaxies in our “neighborhood” (that is, within about ten million light-years of Earth). The Local Group itself is “falling” toward the Virgo Cluster of Galaxies, a set of over one thousand galaxies about fifty million lights years away in the direction of the constellation of Virgo, and whose gravity pulls the Milky Way. http://goo.gl/0ujfi
Things move, and things change. We see it here, as well as out there. We can never say that we know “the way things have always been”, let alone “the way things always will be”. New data with new challenges means necessary adaptation, and lessons from history can only ever be partially applied.
