Our wonderful suburban lives are going on, in denial of the vast powers of the universe.  Our comfort zone extends sometimes blocks, or miles from our house.  Feeling safe in the company of other humans, does not erase the fact, that we are on a spinning orb, totally isolated in the universe,  and moving rapidly through the vastness of space.  Reality Check.
